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.

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.

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.

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.
