After driving faster than 19 mph/30 km/h for a
short period, the tire inflation pressures set are
accepted as reference values. The reset is
completed automatically during driving.
After a successfully completed Reset, the
wheels on the Control Display are shown in
green and "Tire Pressure Monitor (TPM)
active" is displayed.
The trip can be interrupted at any time. If you
drive away again, the reset resumes automati‐
cally.
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.
▷
No reset was performed for the system.
The system therefore issues a warning
based on the tire inflation 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
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 necessary.
Actions in the event of a flat tire
