Wheels and tires
Tire pressure monitor
Principle
The Tire Pressure Monitor monitors the tire
pressure and issues a warning if the tire pres-
sure has dropped.
General information
Sensors in the tire valves measure the tire in-
flation pressure and tire temperature.
Depending on the tire entered or detected, the
system automatically compares the specified
nominal pressures with the current tire pres-
sures.
If tires are being used that are not specified
in the tire inflation pressure details on the ve-
hicle such as tires with special approval, the
system needs to be actively reset. The system
will then take over the actual tire inflation pres-
sures as the target pressures.
When operating the system, also note the in-
formation found in the Tire inflation pressure
chapter.
Additional information:
Tire inflation pressure, refer to page 292.
Safety information
Warning
Incorrect entries in the tire settings can lead
to incorrect target tire inflation pressure val-
ues. In this case, it cannot be guaranteed that
the notification of a tire pressure loss will be
reliable. There is a risk of injury and risk of
damage to property. Make sure that the sizes
of your mounted tires are displayed correctly
and match the information on the tires and
the tire inflation pressure specifications on
the vehicle.
