Keep your GLS550 running newer, longer. Schedule an engine tune-up as soon as you notice your engine running differently. Make your appointment today.
Is it tune-up time? If you usually wait until your car has an issue to take it in for service, now is the time to work on that habit, especially if you drive a 2018 Mercedes-Benz GLS550. Regular engine tune-ups can optimize your GLS550’s power on the road. Tune-ups give your engine a boost in efficiency, which can lead to lower emission levels and better fuel economy. When you get routine engine tune-ups based on Mercedes-Benz's recommendations, you can rest assured you’re investing in your GLS550’s long-term engine performance.
Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Mercedes-Benz GLS550 engine tune-up services. The first is the standard Firestone Tune-Up. It includes a complete visual inspection of engine components, installation of new spark plugs, and a lifetime warranty on parts*. A second service option replaces the air and fuel filter in your GLS550. The third tune-up option is a fuel system cleaning service, which is a three-step process that removes varnish, dirt, and carbon deposits on your GLS550's fuel injectors, throttle body, and throttle plate. This goes a long way in boosting your fuel system’s overall performance. Consider this when choosing a tune-up service for your GLS550: your vehicle’s maintenance record and mileage can determine which service is best. A one-size-fits-all engine tune-up procedure doesn’t necessarily exist. Talk to a technician about your driving style, mileage, and service history to learn more about your vehicle's specific needs.
Schedule your next 2018 GLS550 engine tune-up service at Firestone Complete Auto Care. Consult your vehicle’s recommended service schedule from Mercedes-Benz, or make a service appointment if you notice any of these symptoms from your engine: stalling or shaky idling when you’re stopped, diminished fuel economy, engine knocking, or an illuminated check engine light.
