Safety information
WARNING
The display of the target pressures is not
a substitute for the tire inflation pressure de‐
tails on the vehicle. Incorrect entries in the tire
settings can lead to incorrect target tire infla‐
tion pressure values. In this case, it cannot be
guaranteed that the notification of a loss of tire
inflation pressure will be reliable. There is a risk
of injury and risk of damage to property. En‐
sure that the tire sizes of the mounted tires are
entered correctly and match the details on the
tires and on the vehicle.◀
Functional requirements
The following conditions must be met for the
system; otherwise, reliable flagging of a loss of
tire inflation pressure is not assured:
▷ Every time a tire or wheel is changed, the
correct details on the mounted tires must
be entered in the tire settings, refer to
page 282.
▷ For tires with special approval:
▷ After a tire or wheel replacement, a re‐
set was performed with the correct tire
inflation pressure.
▷ After the tire inflation pressure was ad‐
justed to a new value, a reset was per‐
formed.
▷ Wheels with TPM wheel electronics.
Tire settings
General information
The tire sizes of the mounted tires can be
gathered from the tire inflation pressure details
on the vehicle, refer to page 268, or directly on
the tires.
The tire details do not need to be re-entered
when the tire inflation pressure is corrected.
For summer and winter tires, the tire details
entered last are stored. After a tire or wheel re‐
placement, the settings of the tire sets used
last can be selected.
