Safety information
Warning
Incorrect entries in the tire settings can lead to
incorrect target tire inflation pressure values. In
this case, it cannot be guaranteed that the noti‐
fication of a loss of tire inflation pressure will be
reliable. There is a risk of injury and risk of dam‐
age to property. Ensure that the tire sizes of the
mounted tires are displayed correctly and
match the details on the tires and on the vehi‐
cle.
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.
▷ The Tire Pressure Monitor does not activate
until after driving for a few minutes:
▷ After a tire or wheel replacement.
▷ After a reset, for tires with special appro‐
val.
▷ After changing the tire setting.
▷ 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 wheel electronics.
