For Canadian models: additional
information
The status display additionally shows the cur‐
rent tire inflation pressures and tire tempera‐
tures.
When correcting the tire inflation pressures,
note the following:
The tire pressure increases as the tire temper‐
ature increases.
Therefore, only correct the tire inflation pres‐
sure when the tire is at the ambient temperature.
Compare the displayed tire temperature with
the external temperature in the instrument clus‐
ter.
Resetting the system
Reset the system after each correction of the
tire inflation pressure and after every tire or
wheel change.
1.
"Vehicle Info"
2.
"Vehicle status"
3.
"Reset"
4.
Start the engine - do not drive away.
5.
Reset the tire pressure using "Reset".
6.
Drive away.
The tires are shown in gray and "Resetting
TPM..." is displayed.
After driving for a few minutes, the set tire infla‐
tion pressures are applied as set values. The re‐
setting process is completed automatically dur‐
ing driving. The tires are shown in green and
"TPM active" is shown on the Control Display.
The trip can be interrupted at any time. If you
drive away again, the process resumes auto‐
matically.
If a flat tire is detected during a reset, all tires are
displayed in yellow.
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.
▷
The system was not reset after a wheel
change and thus warns based on the infla‐
tion pressures initialized last.
1.
Reduce your speed and stop cautiously.
Avoid sudden braking and steering maneu‐
vers.
2.
Check whether the vehicle is fitted with reg‐
ular tires* or run-flat tires*.
Run-flat tires, refer to page
with a circular symbol containing the letters
RSC marked on the tire sidewall.
When a low inflation pressure is indicated, DSC
Dynamic Stability Control is switched on if nec‐
essary.
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.
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.
Rectify the flat tire.
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 re‐
placed if necessary.
Run-flat tires*
You can continue driving with a damaged tire at
speeds up to 50 mph/80 km/h.
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.◀
