Safety information
Warning
The display of the target pressures is not a
substitute for the tire inflation pressure details
on the vehicle. Incorrect entries in the tire set‐
tings can lead to incorrect target tire inflation
pressure values. In this case, it cannot be guar‐
anteed that the notification of a loss of tire infla‐
tion pressure will be reliable. There is a risk of
injury and risk of damage to property. Ensure
that the tire sizes of the mounted tires are dis‐
played 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:
▷ After each tire or wheel change, the system
detects and updates the mounted tires and
displays them after a short trip on the Control
Display.
Enter the information about the mounted
tires in the tire settings when the system
does not automatically detect the tires.
▷ For tires with special approval:
▷ After a tire or wheel replacement, a reset
was performed with the correct tire infla‐
tion 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 information about the mounted tires can be
entered in the tire settings if the system does not
automatically detect the tires.
The tire sizes of the mounted tires can be gath‐
ered from the tire inflation pressure details on the
vehicle, refer to page
252 , 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 en‐
tered last are stored. After a tire or wheel re‐
placement, the settings of the tire sets used last
can be selected.
