they may vary depending on driving style or
weather conditions.
Carry out reset
Reset the system after each adjustment of the
tire inflation pressure and after every tire or
wheel change.
1. Start the engine - do not drive off.
2.
Press button.
3. "Vehicle Info"
4. "Vehicle status"
5. "Tire Pressure Monitor (TPM)"
6. To reset the tire pressure: "Perform reset"
7. Drive away.
"Resetting…" is displayed.
After driving faster than 19 mph/30 km/h for a
short period, the set tire inflation pressures are
accepted as reference values. The resetting
process is completed automatically while driv‐
ing.
You may interrupt this trip at any time. When
you continue the reset resumes automatically.
Low tire pressure message
The yellow warning lamp lights up. A
Check Control message is displayed.
▷ There is a flat tire or a major loss in
tire inflation pressure.
▷ A reset of the system was not carried out
after a wheel was changed. The system
therefore issues a warning based on the tire
pressures before the last reset.
1. Reduce your speed and stop cautiously.
Avoid sudden braking and steering maneu‐
vers.
2. Check whether the vehicle is fitted with
regular tires or run-flat tires.
Run-flat tires, refer to page 184, are la‐
beled with a circular symbol containing the
letters RSC marked on the tire's sidewall.
Do not continue driving without run-flat
tires
Do not continue driving if the vehicle is not
equipped with run-flat tires; continued driving
may result in serious accidents.◀
A low tire inflation pressure might turn on DSC
Dynamic Stability Control.
Actions in the event of a flat tire
Normal tires
1. Identify the damaged tire.
Do this by checking the air pressure in all
four tires.
The tire pressure gauge of the Mobility Sys‐
tem, refer to page 185, can be used for this
purpose.
If the tire inflation pressure in all four tires is
correct, the Tire Pressure Monitor may not
have been initialized. In this case, initialize
the system.
If an identification is not possible, please
contact the service center.
2.
Fix the flat tire using the Mobility System,
refer to page 185.
Use of tire sealant, e.g., the Mobility System,
may damage the TPM wheel electronics. In this
case, have the electronics checked at the next
opportunity and have them replaced if needed.
Run-flat tires
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
If continuing to drive with a damaged tire:
1.
Avoid sudden braking and steering maneu‐
vers.
2. Do not exceed a speed of 50 mph/80 km/h.
