Using the ABS sensors, the t ire pressure mon i-
toring system compa res the t ire tread circum-
fe rence and vibration characteristics of the in-
dividual tires. If the pressure decreases in one
or mo re tires, th is is indicated in the instru -
ment cluster with a
ti]
warn ing symbol and a
message ¢

The driver message in the
disp lay goes out after S seconds. The driver
message can be displayed again by pressing
the

button. If only one tire is affected,
the display will indicate its position .
The t ire pressure monitoring system must be
reset via radio or MMI* each t ime the pres-
sures are adjusted (e.g . when switching be-
tween partia l and full load pressure) or after
changing or replacing a t ire on your vehicle

the instrument cluster display, one or
more of your t ires is sign ificant ly unde r-
inflated . Reduce you r speed immediately
and avoid any hard steer ing or braking
maneuvers. Stop as soon as possib le and
check the tires and their pressu res. In-
f late the tire pressure to the prope r pres-
sure as indicated on the vehicle's tire
pressure label
¢ page
226. Driving on a
sign ificantly under-inflated tire causes
the t ire to overheat and can lead to tire
fa ilure. Under-inflation also is likely to
impair the vehicle's handling and stop-
ping ability .
- The drive r is responsib le for maintaini ng
the correct tire pressures . You must
check the tire pressures regu larly.
