Schedule Service

A burning smell from the car, but not overheating, often points to an electrical short, a fluid leak contacting hot surfaces, or clutch slip in manual vehicles. The absence of overheating doesn’t mean everything is fine — it just means the engine coolant system isn’t the source.

If you’ve needed to use a spare tire, you’ve probably found yourself wondering how long you can drive on your spare tire. A standard compact spare is designed for short-term use, typically no more than 50 to 70 miles.

To replace the battery in your Cadillac’s key fob, follow this process:

1. Locate the release button that frees the internal key. Press to open and the mechanical key should slide out.
2. You should see a small seam where the key fob opens. Use the tip of the key to insert into the slot and gently twist.
3. Remove the old battery.
4. Insert the new battery with the positive side facing up.
5. Snap the key fob back together

Most car batteries will last anywhere from 3 to 5 years, depending on climate and driving habits.

The quickest way is the online scheduler at the top of this page. Choose your vehicle, pick the services you need, and select a date and time that fits your week. If you’re not sure what your Cadillac needs, just describe what you’re noticing in the notes and our service advisors will take it from there when you arrive.

A little preparation helps us get you back on the road faster. We recommend bringing:

• Your key fob, plus your wheel lock key if your vehicle has locking lug nuts.
• A short description of any noises, smells, vibrations, or warning lights, including when they happen.
• Any recall notice you’ve received in the mail.
• Printed or saved service offers you’d like applied to your visit.

Most gas-powered Cadillac models use an oil life monitoring system that calculates when your oil needs changing based on how and where you drive, so there’s no single mileage number that fits every owner. When your Driver Information Center shows a low oil life percentage or a “Change Oil Soon” message, it’s time to book an oil change. Your owner’s manual lists the recommended schedule for your specific model.

Yes. A warning light is your vehicle’s way of telling you something needs attention. As a general rule, a red light means pull over safely and address it right away, while a yellow or amber light means have it checked soon. A flashing check engine light should be treated as urgent. Our guide to Cadillac dashboard symbols explains the most common lights, and our technicians can run a diagnostic to pinpoint the exact cause.

Nobody knows your Cadillac better than a Cadillac Certified Service team. Our technicians work on these vehicles every day, use factory diagnostic equipment built for Cadillac systems, and install genuine parts designed for your specific model. That matters more than ever with today’s advanced driver assistance features, connected technology, and electric powertrains.

They skip oil changes, but EVs still need routine care. Tire rotations are especially important because electric vehicles are heavier and deliver instant torque, which can wear tires faster. Brake inspections, cabin air filter replacement, coolant checks for the battery thermal system, and software updates are all part of keeping a Cadillac EV running at its best. When you schedule, select your EV and our team will recommend the right services for its mileage.

Watch for squealing or grinding when you stop, a brake pedal that feels soft or sinks toward the floor, vibration through the pedal or steering wheel, or your vehicle pulling to one side while braking. Any of these means it’s time for a brake inspection. Catching worn pads early can save you from a more expensive rotor replacement later.

Follow the rotation interval in your owner’s manual, and many drivers find it easiest to rotate at the same time as an oil change. Replace tires when tread gets low, when you see cracks, bulges, or uneven wear, or when your tires are getting up there in age even if the tread looks fine. Our tire center can measure your tread and help you find the right fit using our Tire Finder.

Cold weather is tough on batteries, tires, and fluids, so fall is the ideal time for a checkup. Before the first real freeze, we suggest:

• A battery test, since cold temperatures reduce starting power.
• A tire inspection, and a look at winter tires if you drive a lot in snow.
• Fresh wiper blades and winter-rated washer fluid.
• A coolant and antifreeze check.

Unexpected repairs don’t always line up with your budget. Our Service Now, Pay-Over-Time program lets you take care of your vehicle now and spread out the cost. Visit the program page for details on how it works and how to apply.
