system
The tire pressure loss warning system warns the driver by means of display messages when there
is a severe tire pressure loss.
Systemlimits
The system may be impaired or may not function particularly in the following situations:
= incorrectly set tire pressure
= sudden pressure loss caused, for example,
by a foreign object penetrating the tire
= steady pressure loss in several tires
The system has a restricted or delayed function
particularly in the following situations:
= poor ground conditions, e.g. snow or gravel
= driving with snow chains
=when adopting a very sporty driving style
with high cornering speeds or sudden accel

After you have driven for a few minutes, the
tire pressure loss warning system monitors the set tire pressures of all the tires.
