How to Reset a Run Flat Indicator on a Mercedes-Benz

Run Flat Indicator


Do you have run-flat tires installed on your Mercedes-Benz vehicle? If so, then you may experience the activation of the run flat indicator, which alerts you to a loss of pressure in one of your tires. This tire pressure loss warning for Mercedes-Benz allows you the opportunity to get to a nearby mechanic or gas station in the Oakville area to inflate the tire. Do you know how to reset a run flat indicator on a Mercedes-Benz, if it doesn’t automatically do so after tire pressure is addressed? Find out in this guide from Mercedes-Benz Burlington.


How to Reset Run Flat Indicator on Newer Models

  • Drive at or above 21 km/h to reset the sensor for 10 minutes. Doing this alone can cause your sensor to reset the next time you turn on the car.
  • Keep your vehicle off, turn the key to the “On” position, but don’t start the car. Next, hold the TPMS reset button and wait until the tire pressure light blinks three times, then release it. 
  • Now start your car and wait 20 minutes for the sensor to refresh. The tire pressure monitor reset button is usually located beneath the steering wheel. If you have trouble locating it, you can check your owner’s manual. 
  • Inflate all tires (including the spare tire as it can also have a sensor) to 3 PSI over their recommended amount, then completely deflate them. After they’ve been deflated, inflate them to their recommended pressure.
  • Keeping your vehicle off, disconnect the positive battery cable with a wrench. Next, start the car and honk the horn for about three seconds. Doing so will release any charge stored in your vehicle. You can then reconnect the battery.

How to Reset Tire Pressure Loss Warning on Older Cars

The tire pressure loss warning is emitted via the run flat indicator, which appears on the multifunction display of your Mercedes-Benz. Here is how to reset the tire pressure loss warning if you have already adjusted the tire pressure or installed new tires after a flat tire.

  1. Before you begin, ensure that all four tires have the correct tire pressure.
  2. With your key in position 2 in the ignition, use the steering wheel controls to select the Serv. menu, followed by Tire Pressure. Press OK.
  3. At this point, the run flat indicator active restart should appear in the multifunction display. Press OK to confirm the restart.
  4. A message should appear confirming that your tire pressure is now okay, to which you should select yes and press OK.
  5. You will now see a run flat indicator restarted message in the multifunction display. The tire pressure loss warning for Mercedes-Benz will continue to monitor the set tire pressures of all four tires.

Benefits of Run Flat Indicator

Run-flat tires are beneficial in that they allow you to continue to drive slowly when tire pressure is low, permitting minimal movement from the depleted tire as long as it isn’t damaged. Though they aren’t a surefire way to avoid tire blowouts, run-flat tires can help in getting you somewhere that you can address the tire pressure loss warning. Of course, there is no substitute for proper tire care, so make sure to keep up with regular tire rotations, check tire pressure on a consistent basis, and monitor tire tread depth.
