Operation
Tires and wheels
USA only: When the malfunction indicator is
illuminated, the system may not be able to
detect or signal low tire pressure as
intended.
USA only: Advanced TPMS malfunctions
may occur for a variety of reasons, including
the installation of replacement or alternate
tires or wheels on the vehicle that prevent
the Advanced TPMS from functioning prop-
erly. Always check the Advanced TPMS mal-
function telltale after replacing one or more
tires or wheels on your vehicle to ensure
that the replacement or alternate tires and
wheels allow the Advanced TPMS to contin-
ue to function properly.
i
Operating radio transmission equipment
(e.g. wireless headsets, two-way radios) in or
near the vehicle could cause the Advanced
TPMS to malfunction.

Tire inflation pressure warnings
If the system detects a significant loss of
tire inflation pressure in one or more than
one tire, a message appears in the multi-
function display.
Example illustration
The respective tire is indicated by a red
rectangle. In addition, a warning signal
sounds.
Restarting Advanced TPMS
The TPMS usually recognizes new refer-
ence values automatically, for example
when you have
adjusted the tire inflation pressure
changed wheels or tires
mounted new wheels or tires
Warning!
It is the driver's responsibility to calibrate
the TPMS on the recommended cold infla-
tion pressure. Underinflated tires affect the
ability to steer or brake the vehicle. You
might lose control over the vehicle.
