Important safetynotes
The tire pressure warning system does not
warn you of an incorrectly set tire pressure.

pressure (Y page 271).

replace the need to regularly checkthe tire
pressure. An even loss of pressure on several
tires at the same time cannot be detected by
the tire pressure loss warning system.
The tire pressure monitor is not able to warn
you of asudden loss of pressure, e.g. if the
tire is penetrated by aforeign object. In the
event of asudden loss of pressure, bring the
vehicle to ahalt by brakingcarefully. Avoid
abrupt steering movements.
