All wheels are yellow
▷ A flat tire or major drop in inflation pressure
in several tires.
▷ The system was not reset after a wheel
change and thus issues a warning based on
the inflation pressures initialized last.
▷ A flat tire in one or more tires while the sys‐
tem is being reset.
Wheels, gray
The system cannot detect a flat tire.
Reasons for this may be:
▷ TPM is being reset.
▷ Disturbance by systems or devices with the
same radio frequency.
▷ Malfunction.
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. Start the initialization with "Reset".
6. Drive away.
The tires are shown in gray and "Resetting
TPM..." is displayed.
After driving a few minutes, the set inflation
pressures in the tires are accepted as the target
values to be monitored. The resetting process is
completed automatically as you drive. On the
Control Display, the tires are shown in green
and "Status: TPM active" is displayed again.
The trip can be interrupted at any time. If you
drive away again, the process resumes auto‐
matically.
If a flat tire is detected while the system is re‐
setting, all tires on the Control Display are dis‐
played in yellow. The message "Low tire!" is
shown.
Low tire pressure message
The warning lamps come on in yellow
and red. A message is displayed on the
onboard monitor. In addition, a signal
sounds.
▷ There is a flat tire or substantial loss of infla‐
tion pressure on the indicated wheel.
▷ The system was not reset after a wheel
change and thus issues warnings based on
the inflation 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
regular tires or run-flat tires.
Run-flat tires, refer to page 219, are la‐
beled with a circular symbol containing the
letters RSC marked on the tire 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.◀
When a low inflation pressure is indicated, DSC
Dynamic Stability Control is switched on if nec‐
essary.
