Normal tires
1. Identify the damaged tire.
Check the tire inflation pressure in all four tires, for instance using the tire pressure gage of a flat tire kit.
For tires with special approval: if the tire inflation pressure in all four tires is correct, the TPM may not have been reset. In this case, perform the reset.
If tire damage cannot be found, contact a dealer's service center or another qualified service center or repair shop.
2. Repair the flat tire, e.g., with a flat tire kit or by changing the wheel.
Use of sealant, for instance from the flat tire kit, may damage the TPM wheel electronics. Have the electronics replaced at the next opportunity.
Run-flat tires
Safety information
Warning
Your vehicle handles differently with a run-flat tire with no or low inflation pressure; for instance, your lane stability when braking is reduced, braking distances are longer and the self-steering properties will change. There is a risk of accident. Drive moderately and do not exceed a speed of 50 mph/80 km/h.
Maximum speed
You may continue driving with a damaged tire at speeds up to 50 mph/80 km/h.
Continued driving with a flat tire
Follow the following when continuing to drive with a damaged tire:
1. Avoid sudden braking and steering maneuvers.
2. Do not exceed a speed of 50 mph/80 km/h.
3. Check the tire inflation pressure in all four tires at the next opportunity.
Possible driving range with a depressurized tire
The distance for which it may be possible to drive safely varies depending on how the vehicle is loaded and used, e.g., speed, road conditions, external temperature. The driving range may be less but may also be more if an economical driving style is used.
If the vehicle is loaded with an average weight and used under favorable conditions, the distance for which it may be safe to drive may be up to 50 miles/80 km.
Vehicle handling with damaged tires
Vehicles driven with a damaged tire will handle differently, potentially leading to conditions such as the following:
Modify your driving style. Avoid abrupt steering maneuvers or driving over obstacles, for instance curbs or potholes.
Final tire failure
Vibrations or loud noises while driving can indicate the final failure of a tire.
Reduce speed and stop; otherwise, pieces of the tire could come loose and cause an accident.
Do not continue driving. Contact a dealer's service center or another qualified service center or repair shop.
System limits
Temperature
The tire inflation pressure depends on the tire's temperature.
Driving or exposure to the sun will increase the tire's temperature, thus increasing the tire inflation pressure.
The tire inflation pressure is reduced when the tire temperature falls again.
These circumstances may cause a warning when temperatures fall very sharply.
Following a temperature-related warning, the target pressures are displayed on the Control Display again after a short distance.
Sudden tire pressure loss
The system cannot indicate sudden serious tire damage caused by external circumstances.
Failure performing a reset
Tires with special approval: the system will not function correctly if a reset was not performed, for example a flat tire may be indicated although the tire inflation pressures are correct.
