Mercedes FAQs
How do I get the radio code for my car?
Take a look at the owner’s manual, sometimes the code is written on a small business card, or the front or back of the manual. You can also contact the carmaker with the Vehicle Identification Number (VIN) that is visible through the front windshield. Of course, we can always help you with this, or any type of car software or hardware issue. As the premier European auto service shop in Seattle—that’s just what we do!
I see an “Anti-theft protection active” message on my COMAND screen. What do I do?
The “Anti-theft protection active” message tells you that your COMAND unit is not detecting your internal vehicle network. Fortunately, this doesn’t mean that your anti-theft alarm isn’t working. One solution is to press down and hold the COMAND power button for about ten seconds which resets connectivity. If this doesn’t work, try restarting your vehicle. If neither of these work, contact us online or call 206-527-8828.
How do I set up my Bluetooth?
- Press the phone button on your steering wheel to access the pairing menu and select the phone option from the home menu.
- Make sure that your mobile device’s Bluetooth® and the device list is visible during the pairing process.
- Select “Connect a New device”, then “Start Search on System” on your infotainment screen.
- Choose the desired mobile device from the device list. A code then displays on the infotainment screen and your device.
- If the codes match, confirm the code on your mobile device.
Why is my tire pressure warning light coming on occasionally?
Properly functioning tires will lose air over time, up to 1-2 psi per month, so it could be normal air loss or a leaking tire. Tires also lose 1-2 psi of pressure for every 10-degree drop in ambient temperature. Parking outside after being in a warm garage can therefore drop pressure and cause the light to temporarily illuminate. We recommend that you check your tires with a high-quality gauge once per month and bring them in to be rotated regularly.
What kind of diesel should I use?
Check your owner’s manual. Depending on the model year, Mercedes-Benz diesel engines require the use of either diesel grades 1–D and 2-D, or ultra-low sulfur diesel fuel (15 ppm sulfur maximum). Older diesel vehicles can use the new Ultra Low Sulfur Diesel Fuels (ULSDF). By the way, MBUSA does currently approve of any fuel additives for its diesel vehicles.
How do I find out if my vehicle has been issued a recall notice?
You should receive a letter if there is a recall on your car. If your address has changed or you otherwise suspect you have not been contacted, we can look it up by VIN or you can contact the carmaker.
What grade of gasoline should I use?
All cars require premium unleaded that is 91 octane or higher. Check your owner’s manual or contact us online or give us a call at 206-527-8828 if you have further questions.
What pressure should I run my tires at?
The tire pressure label located on the inside of the fuel filler door gives you normal and maximum load levels. These settings optimize ride-quality, fuel economy, and tire lifespan. The tire pressure label on the right side of the driver door jamb shows maximum allowable pressure for the model. Tire pressure labels located on the outside of the tires displays maximum tire pressure for that particular tire.
Where is the best place for a road, bridge, or other transponder?
Because many Mercedes vehicles have infrared reflecting windshields, there are only certain areas that are permeable by the radio waves sent out and received by transponders. These are located at the top of the windshield to the left or right of the rearview mirror and along the bottom in the center. Check your owner’s manual if your transponder is not transponding or give us a call to find out what type of glass you have and where to put your transponder.
