Your Toyota hybrid vehicle uses a traditional gasoline engine with an electric motor to provide eco-friendly, economical power. A hybrid battery drives the motor. Regular Toyota hybrid battery maintenance extends your vehicle's lifespan and ensures you enjoy peak performance every time. Smooth Driving Jerky driving can take its toll on the battery. Every time you accelerate or brake, the electric motor requires power, which has to come from the battery. Smooth driving means the ongoing power demand is lower, which reduces the risk of premature wear. more Avoid Extreme Temperatures Batteries don't respond well to extreme temperatures. Regular exposure to both hot and cold temperatures can lower the battery's overall lifespan. You can minimize the effects of the weather by taking steps to protect your Toyota in both the summer and winter. You can opt to park in the shade, use a cover, or leave your car in a garage where possible to shield it from the worst effects. Take Longer Trips Short trips can drain the battery and don't provide the opportunity for it to recharge. Regenerative technology allows your battery to recharge as you drive but it requires a longer trip for maximum efficiency. Combine shorter trips when possible and drive longer distances periodically to keep your battery in prime condition. Don't Charge to the Max It may sound strange, but a full charge of 100 percent can be harmful to your battery. Over time, repeated full charges can reduce a battery's lifespan. You may be able to limit the charge with your battery management system, but if not, you can monitor it manually. The charge should be kept at around 80%, ideally. Never Allow the Battery to Drain Completely A dead battery is just as harmful as one that has been charged to 100 percent. You can protect the life of your battery with a charge of 20% or above. Drive Your Car Regularly Logic may suggest that resting your car for extended periods may help it last even longer, but the reverse is true. The health of your battery decreases when it is stationary, even for short periods. If the battery drains completely and your car sits idle, the lifespan will be adversely affected. Run your car for at least 20–30 minutes every week or two to protect the hybrid battery. Arrange Regular Maintenance The precision engineering on your Toyota means that every system is designed to work in perfect balance. If there's a problem with one component, it can affect the performance of your car. When your car isn't at its best, the battery may be under more stress with greater power requirements. Keeping your tires, brakes, and other systems well-maintained protects your battery too. If your Toyota is due for maintenance, we can help.

When you're ready to buy a new vehicle, car financing is often the biggest challenge. Fortunately, your Toyota dealer has a dedicated finance team that can walk you through all of your options so you can find a financing plan that works with your budget and car ownership goals. Financing Options for Service at Coughlin Toyota In general, your financing options for a new or used vehicle will be an auto loan or a car lease. If you're tight on cash and prefer to trade your vehicle for a newer model, then leasing might be ideal for you. When you lease a car, you usually have a low monthly payment. The trade-off is that you may have to comply with yearly mileage limits and you may have end-of-lease fees for wear and tear. Buying a vehicle, on the other hand, is a long-term plan for drivers who want to eventually own the vehicle. When you buy a car, you will typically need to have a downpayment, such as 10 to 20% of the vehicle's value. Your monthly auto loan payments may be marginally higher with this financing option, but you will also have more freedom in how many miles you can drive and any customizations you may want to make. more Can You Buy a Car Even If You Lease? If you start off leasing your vehicle but decide you want to own your car in the future, you can discuss end-of-lease options with your dealership. End-of-lease payments can include extending your lease or buying out your lease by paying the residual value of the vehicle. Can You Get Car Financing Even With Poor Credit? When you get vehicle financing through your dealership, a history of bad credit isn't an obstacle. While banks and credit unions may turn down your finance application because of a low credit rating, your local dealership is willing to work with you to find a competitive loan for your unique credit situation. That said, you can expect your interest rate to be higher if you have poor credit. If you want to reduce your interest rate even if you have a poor credit history, there are several things you can do. Making credit card payments on time, relying on cash more than your credit cards, and cleaning up your credit report by challenging errors or closing down old accounts you don't use anymore are all ways you can improve your credit score. It may take a few months for your credit score to reflect these changes. Whether you buy or lease your vehicle, your local dealership has plenty of flexible options for you to explore. Get in touch with Coughlin Toyota in Heath, OH to talk to a finance advisor today.

While out on the road, the condition of a car's brakes can sometimes mean the difference between life and death. For safety-conscious drivers, brakes are possibly the most important car part to maintain with care and diligence. Bearing this in mind, here's an outline of proper brake maintenance, including when to visit your local Toyota dealer for brake repairs or servicing. Book Biannual Brake Servicing at Your Toyota Dealer As with motor oil changes and tire rotations, brake servicing should be carried out at least twice a year. For thorough brake maintenance, the technician needs to raise your vehicle to remove the wheels and each brake component. With an expert eye, they can then inspect each rotor disc, brake pad, caliper, and brake line for signs of excessive wear or leaking brake fluid. They'll also check the brake fluid levels and top it up if required. more How Brake-Heavy Are Your Driving Condition? Some drivers put their vehicle's brakes through more usage than usual. If your daily driving conditions mean your foot is on the brake pedal a great deal, you might need to have your brakes serviced more frequently than most. Some examples of brake-heavy conditions are towing heavy trailers, carrying heavy loads, stopping and starting in busy urban traffic, and driving along mountainous roads with long downhill stretches. Do You Have Brake-Heavy Driving Habits? Some people have a brake-heavy driving style and tend to use the brake pedal excessively. These drivers often accelerate too much and then brake more to compensate rather than taking their foot off the gas and allowing gravity to slow their car down. If you find yourself riding the brakes a little too much, your brake pads and rotors are likely to need replacing more frequently. When you take your car in for regular brake servicing, the technician can let you know how much wear and tear you typically put your brakes, through. Watch Out for Signs That You Need Brake Repair The other side of the coin with brake maintenance is prompt responsiveness to signs of brake trouble. If you ever notice your brakes emitting a high-pitched squealing sound, for example, one of your brake pads may need replacing. Grinding noises might indicate the same issue, albeit more urgently. Other indications of brake problems include vibrations from damaged rotor discs and any unexpected loss of stopping power. And if your brakes ever feel spongy underfoot or you notice a puddle of light yellow transparent fluid under your car, you might have a brake fluid leak, which would need to be found and fixed immediately. Have your car's brakes serviced today at Coughlin Toyota in Heath, OH. At our welcoming full-service dealership, you can expect an outstanding customer experience, whatever your vehicle purchasing or servicing needs might be.

Maintenance To Get at the Toyota Dealer Oil and Filter Swaps Changing your oil and filter regularly keeps your car healthy. Depending on how you drive and what model you have, you'll want to do this every 5,000 to 7,500 miles to keep your engine happy. Tire TLC Tires feeling a little deflated? Keeping them pumped to the right pressure not only saves on gas but makes for a smoother ride. And don't forget about rotating them every so often to get more mileage out of each set. Brake Checks Your brakes are pretty darn important, so giving them a once-over regularly ensures you can always stop on a dime. This includes checking pads, rotors, and fluid to keep everything responsive. Fluids Galore Your Toyota's got a thirst for various fluids to keep cool and run smoothly. From coolant to transmission fluid, keeping them topped up and fresh is key to a happy car. Battery Business No one likes being left stranded. A quick check of your battery's health and keeping those terminals clean can save you from surprise start-up woes. Air Filter Refresh Your Toyota appreciates clean air as much as you do.

Schedule Regular Oil Changes Sticking to the schedule of oil changes recommended for your model is one of the most important things you can do to maintain your vehicle. Changing your oil keeps the moving parts of your engine lubricated and running smoothly. When your vehicle is in for an oil change, we'll also check other fluid levels, rotate your tires, check to make sure all of your lights are working, and inspect other important systems. Oil changes are usually brief service appointments that can be completed in less than an hour, but they're a great way for us to check in on the overall condition of your vehicle. 3. Check Your Tires Keeping your tires properly inflated and in good condition is another important step that supports the long-term maintenance of your vehicle.

It also maximizes fuel efficiency and minimizes wear on vehicular systems like the brakes and suspension. 4.

Regularly Check and Replace Your Air Filters Regularly checking and replacing your vehicle's air filters helps prevent dirt and dust from getting into the engine.

Your Toyota is designed to be reliable, carrying you from point A to point B without a fuss. Like all vehicles, it relies on a trusty battery to start and run smoothly every day. So when the time comes to get a new car battery from the Toyota dealer, it's important to understand the process. Car Battery Basics A car battery provides the electrical current your Toyota needs to start the engine. It also powers the car's electronics when the engine isn't running. Typically, a car battery lasts between 3 to 5 years, but this can vary based on your climate and driving habits. It's a good practice to have your battery checked regularly once it hits the three-year mark. more Signs You May Need a New Car Battery Before a battery fails, it often shows some warning signs. Your check engine light might flicker on, and some modern Toyotas also have a battery light on the dashboard that signals when there's a battery or charging system issue. Here are some other signs that it's time to consider a replacement. Slow Engine Crank When your car's battery is failing, you might notice that the engine turns over more slowly than usual when you try to start it. Trouble Starting If you're having trouble getting your car to start, especially on cold mornings, it could mean your battery is on its way out. Swollen Battery Case A battery case can swell due to excessive heat exposure. This means your battery isn't working normally and can actually be a hazard, so if your case is swollen, the battery should be replaced immediately. Corrosion on the Battery Terminals If you see a white, powdery substance on your battery, that's corrosion. It can be a sign that your battery is getting too old and damaged and is not working properly. Frequent Jump Starts Have you needed to jump-start your car frequently? That's a clear sign that your battery is failing and is unable to hold a charge. Get a New Battery at Your Toyota Dealer At the dealership, you'll find batteries specifically designed for your vehicle model. Dealerships can also handle the installation and ensure that everything is working correctly with your car's computer system, making a trip to the dealer the best choice when it's time to replace your battery. Maintaining Your New Battery After installing your new battery, keep it in tip-top shape with simple maintenance. Keep the terminals clean to avoid corrosion, and if you don't drive your Toyota often, consider a battery maintainer to keep the battery fully charged. Getting a new battery for your Toyota can help it run smoothly and correctly for a long time to come, providing you with the reliable performance you've come to expect.

It's important to prioritize your safety on the road, and keeping your Toyota's headlights in good working condition is crucial. The last thing you need at night or in inclement weather conditions is not being able to see the road ahead. Look out for the following warning signs and get new headlights from Coughlin Toyota as soon as possible to avoid being left in the dark. 1. Your Headlights Are Dim Headlights could grow dimmer for various reasons, from dirty and scratched covers blocking the light to a weak battery or bulbs turning yellow with age. Inspect the headlight covers for damage or dirt and replace the bulbs. If your headlights still aren't as bright as they once were, it could be due to an internal problem, such as a wiring issue. Have your Toyota technician examine the headlights to determine what is causing the problem. more 2. Your Headlights Are Flickering If your headlights are flickering, this could indicate a worn or damaged bulb filament or a weak battery. Ignoring this warning sign can lead to bulb failure and leave you stranded in the dark while driving at night or in bad weather. Even if you have replaced the bulb and the flickering persists, there may be a bad connection. Don't put off this issue any longer – have your Toyota technician inspect your headlights and make necessary repairs for your safety. 3. Your High Beams Aren't Working Properly When the high beams are not functioning correctly, even if the low beams are working fine, it could be due to a blown fuse, faulty wiring, or a burned-out bulb. Change the bulb and check the fuses, and if the high beams are still not working properly, it's best to ask your Toyota technician to take a look. 4. A Headlight Bulb Is Out If one of your headlights is not working, chances are high that the bulb has burned out. Keep in mind that the other bulb may also be on the verge of failure because headlights are usually replaced in pairs to ensure the light is evenly distributed to increase visibility. When one bulb stops working, the other is soon to follow. 5. Your Headlights Won't Come On When your headlights fail to turn on, it could be due to a faulty headlight bulb or wiring issues with the headlight assembly. Generally, changing the headlight bulb solves this problem. If the issue still persists after replacing the bulb, ask your Toyota technician to examine the wiring, as it may require replacement. A small investment in your car's maintenance can go a long way in keeping you safe on the road. Call Coughlin Toyota today to schedule a maintenance service and headlight inspection and ensure your Toyota is in tip-top condition.

The engine is the most complex and expensive part of your Toyota. This means that any engine problems need to be checked and fixed ASAP, as a problem in the engine will grow steadily worse and could potentially cause long-term engine damage. Fortunately, this doesn't have to happen, as your Toyota dealership can fix any engine problem for you. These are a few of the problems that we can repair. Oil Leaks Oil is continually pumped through your engine and both cleans and protects the engine as it works. Many engine components depend on friction to work effectively, and this friction could lead to damage. Engine oil coats these components with a protective film to prevent friction damage. The fast-moving oil also helps to reduce the heat generated by many engine components. The most common cause of an oil leak is worn or damaged seals. An oil leak will cause the engine temperature to rise as the oil's cooling effect is steadily lost. In addition, many engine components will be damaged by friction. We can easily trace an oil leak and repair it: then we'll refill your engine with fresh oil. more Damaged Sensors Sensors act as the eyes and ears of your Toyota's computer. These sensors continually feed information to the computer, which allows the computer to make decisions. Sensors can become damaged due to problems in the engine, and they can also fail due to age or electrical supply issues. Failed sensors will transmit little or no information to your computer. The lack of information caused by a damaged sensor will lead to additional problems or damage. A failed oxygen sensor, for example, won't supply your computer with the correct percentage of air in the engine. Air is vital for your engine, as efficient combustion requires a precise air-fuel ratio. Insufficient air in the engine can damage the spark plugs, ignition coils, and the catalytic converter. Our technicians will identify any failed sensors and replace them. Check Engine Light Your dash panel has numerous warning lights that give you an early heads-up if a system has a problem. The most important of these warning lights is the check engine light which lights up in response to any issue affecting your engine. Unlike most other warning lights like the ABS or the low oil light, the check engine light doesn't identify the specific cause of the problem. If your engine light illuminates, we advise visiting our service department ASAP. Our technicians will connect your car's computer to our diagnostic system, and they will quickly identify the source of trouble. Once we know what's wrong, we will fix the problem. Problems in an engine are usually easy and inexpensive to repair if they're detected when they first start. Call us today at Coughlin Toyota.

When you're driving, you need to be able to control your speed at any time. If your brakes aren't working as well as they should, this can make any journey a nerve-wracking experience. Fortunately, when you need a brake repair in Heath, OH, Your Toyota dealer can fix the problem for you. These are some of the signs of brake issues: Soft Brake Pedal When you step on the brake pedal, you expect to feel resistance. As your press harder on the pedal, the resistance increases. The resistance is caused by the pressurized brake fluid. Your braking system is pressurized as this provides the force to slow and stop a vehicle weighing approximately 4,000lbs that is moving at speed. If you feel a slight resistance from the pedal, this is known as a soft pedal, and it's a sign of a problem. A lack of pressure means that you could have a brake fluid leak, or there might be an air bubble in the braking system. Both of these situations reduce the system pressure. Our technicians will find the cause of the problem and fix it for you. more Hard Brake Pedal This is the opposite situation of a soft pedal. In this case, when you step on the pedal, it will barely move, regardless of how much pressure you exert. This problem is due to damage to the brake pedal booster. As we've seen, your brakes are pressurized to stop the weight of your car. The brake pedal booster uses a vacuum system to generate 10x normal human strength. If your booster has been damaged, the vacuum system is compromised. Without the vacuum, the booster won't work, and your brake pedal will barely move. We can examine the booster and replace it to fix this problem. Your Car Takes Longer To Stop When you hit the brakes, you expect your braking system to respond almost immediately and stop your car. If your car is taking longer to stop than it should, this is a sign of a braking problem. Delayed braking is dangerous, as any delay can mean the difference between preventing an accident and becoming part of an accident. One of the possible causes of this delay is worn brake pads. Brake pads have a friction material covering that's 1/2" thick. This material generates friction against the rotors that bring your car to a stop. The material gradually wears off, and your braking response becomes slightly longer. Other possible causes include damaged calipers, a brake fluid leak, or a damaged master cylinder. Our technicians will investigate and repair the problem. Worn or damaged brakes can place you in danger. If your brakes aren't working as well as they should, call us immediately at Coughlin Toyota.

The alternator is a mini generator that provides electricity for your car. On average, your alternator will last eight years before it needs to be replaced. When the alternator starts to wear out, you see signs it's failing. As your Toyota dealer, we can provide an alternator repair. We'd also like you to know some signs that your alternator could be failing. Check Battery Light The battery-shaped light on your dash lights up if a problem is detected in your car's electrical system. This light is connected to sensors attached to your alternator, battery, and other parts of the electrical system. These sensors monitor their attached components for signs of trouble and inform the computer if something is going wrong. One of the problems that can trigger this light is a failing alternator. An alternator usually produces 14.5 volts. If all your electrical systems are running and the battery is recharging, the alternator should still produce at least 13 volts of power. If the alternator has worn down and produces less than 12.5 volts, this will trigger the warning light. Our technicians will test your alternator, and we can replace a failed alternator very quickly. more Dim Lights Dim lights could mean that your headlight bulbs are due for replacement or you have a failing alternator. Headlight bulbs have a relatively short lifespan, but if you've replaced them recently, the alternator could be the problem. As an alternator gets older, its ability to generate power starts to fail. This is a gradual process, but it's irreversible. Eventually, the alternator reaches the point that it can't supply all of your car's electrical needs. Your computer will have to assign the limited available power. It does this by supplying many components with just enough power to switch on. Our technicians will need to test your alternator to determine if it's the cause of the problem. If the alternator is failing, we'll replace it. Grinding Noises Harsh grinding noises when your engine is running can mean your alternator is failing. Your alternator sits on two bearings, one in the front and one at the back. These bearings allow your alternator to spin as the alternator pulley turns. The spinning of the alternator generates electricity. The grinding noise could be from a cracked or broken alternator bearing. The front bearing takes more strain than the rear bearing due to the movement of the alternator belt. If the bearing fails, this will cause damage to the alternator itself. We can replace a damaged alternator bearing if that's the problem, and the harsh sounds will disappear. If your alternator shows signs of strain, call us at Coughlin Toyota.
