What should I do after hitting a pothole in my Mercedes-Benz GL350?

Check your car for pothole damage! If you’ve recently hit a pothole (or even if you don’t remember hitting one… they can be sneaky!) check your tire treads, tire sidewalls, and wheels for damage. Potholes can also knock your car out of alignment, so have your alignment checked if you suspect you’ve driven over a rough patch of road lately.

When should I use high mileage oil in my Mercedes-Benz GL350?

If your Mercedes-Benz GL350 has ticked past 75,000 miles, consider switching to high mileage oil at your next oil change to give your engine what it needs to go another 75,000 (or more!). High mileage oil: make it a high priority!

Can Mercedes-Benz dashboard warning lights wait?

Don't ignore dashboard warning lights! Bring your Mercedes-Benz GL350 in for a diagnostic code scan as soon as a dashboard warning light flashes on, whether it's your check engine or battery light. Dashboard lights alert you to trouble under the hood.

Scheduled Maintenance for Your 2013 Mercedes-Benz GL350

What is the maintenance schedule for the 2013 Mercedes-Benz GL350?

Here’s Why 2013 Mercedes-Benz GL350 Scheduled Maintenance Matters

When it comes to your Mercedes-Benz GL350, how you treat your car makes all the difference in its performance. If you put in the effort to keep up with proper maintenance, your GL350 has a good chance of hitting 200,000 miles or more. So, you want to care for your car, but you’re not sure when to get certain services. Instead of waiting for an issue to arise with your GL350, you can stay ahead of problems before they even begin. Rely on the recommended maintenance schedule that’s been created just for your 2013 Mercedes-Benz GL350!

Mercedes-Benz knows your vehicle inside and out (they made it, after all!), so they’ve designed this schedule with your car’s unique needs in mind. Scheduled maintenance services can vary depending on driving conditions, climate, and other factors; in most cases, though, recommended maintenance will consist of services like oil changes, tire rotations, brake pad replacement, filter changes, and fluid checks and exchanges. Staying on track with routine service appointments can help your GL350 perform better, keep you safer on the road, and prevent common 2013 Mercedes-Benz GL350 problems.

Essential Maintenance to Keep Your Mercedes-Benz GL350 Running Newer, Longer

Head to your nearest Firestone Complete Auto Care in your 2013 Mercedes-Benz GL350 for factory-recommended routine maintenance and our technicians will jump right in with a Courtesy Check. The Courtesy Check helps us see what we’re working with under the hood, and allows us to alert you to any potential problems before they worsen. Each Courtesy Check includes a free battery test and an inspection of your GL350's windshield wiper blades, head and tail lights, filters, fluid levels, tires, and alignment.

Maybe it's time to find a new auto battery for your 2013 Mercedes-Benz GL350. Batteries generally need to be replaced every three to five years. Yours may need to be replaced sooner depending on your driving habits and climate. Taking short trips or exposing your car to extreme temperatures (like in the dead of winter or heat of summer) could reduce the life expectancy of your Mercedes-Benz GL350 battery. Sure, you could wait until your battery is completely dead, but it’s a much wiser decision to replace it before you need to. If you keep driving on a battery that can't hold a charge, you run the risk of being stranded when your battery finally gives out (and no one can predict where that might be!). Your Mercedes-Benz GL350 could quickly go from being a trusty ride to a source of stress in a matter of minutes.

Ensuring you always have a well-charged battery can help your car’s overall performance, and regularly scheduled oil changes can help your 2013 Mercedes-Benz GL350's engine run smoother. To learn how often Mercedes-Benz recommends you have the oil changed in your 2013 GL350, check out the information table at the beginning of this page. Don’t forget, though, that weather conditions in your area or your personal driving habits can affect this interval. A Firestone Complete Auto Care technician will be happy to help you determine the best oil change frequency for your car’s needs. We'll also help you understand what type of oil to use for your 2013 Mercedes-Benz GL350.

Maintaining your Mercedes-Benz GL350 steering and suspension system can improve ride comfort and help you maintain control of your vehicle. That's important if you plan on taking the road less traveled! Bring your car to Firestone Complete Auto Care, where our technicians can check your car’s steering components and, if necessary, perform Mercedes-Benz GL350 suspension and steering services. These might include wheel alignment, power steering fluid flushes and replenishments, ball joint lubrication, wheel bearing replacement, and strut replacement. Components within your Mercedes-Benz GL350's steering system require regular maintenance.

If you skip recommended Mercedes-Benz GL350 services, you could be feeling the heat on the road – literally! A malfunctioning A/C system or overheating engine can wreak havoc on your car. Don’t sweat it, though! Our technicians can take care of those issues, too. At Firestone Complete Auto Care, we have what it takes to provide top-notch service for your Mercedes-Benz GL350 engine heating and cooling systems, as well as your air conditioning. Is it time to replace the radiator in your Mercedes-Benz GL350? We’ve got your back. Is your A/C blowing hot air? We'll fix it. Firestone Complete Auto Care is your one-stop shop for 2013 Mercedes-Benz GL350 maintenance and repairs.

Don’t wait until something goes wrong with your car. Visit your nearest location for proactive maintenance today.
