Operation
Tires and wheels
̈ Install the valve cap.
̈ Repeat this procedure for each tire.
Checking tire inflation pressure elec-
tronically with the Advanced Tire Pres-
sure Monitoring System (Advanced
TPMS)*, (standard on U.S. vehicles)
The TPMS only functions on wheels that
are equipped with the proper electronic
sensors. It monitors the tire inflation pres-
sure, as selected by the driver, in all four
tires. A warning is issued to alert you to a
decrease in pressure in one or more of the
tires.
Tire inflation pressure inquiries are made
using the multifunction display. The
present inflation pressures are displayed
only after a few minutes of travel time.
̈ Switch on the ignition (୴ page 344).
̈ Press ( or & to select the menu
“Service”.
̈ Press $ or % to select “Tire
pressure”.
̈ Press #.

If you have overfilled the tire, release tire in-
flation pressure by pushing the metal stem of the
valve with e.g. a tip of a pen. Then recheck the
tire inflation pressure with the tire gauge.

The Advanced Tire Pressure Monitoring
System (Advanced TPMS) is equipped with a
combination low tire pressure/TPMS malfunc-
tion telltale in the instrument cluster
(
୴ page 608). Depending on how the telltale illu-
minates, it indicates a low tire inflation pressure
condition or a malfunction in the TPMS system it-
self:
ț If the telltale illuminates continuously, one
or more of your tires is significantly under-in-
flated. There is no malfunction in the TPMS.
ț USA only:
If the telltale flashes for 60 seconds and
then stays illuminated, the TPMS system it-
self is not operating properly.

Possible differences between the readings
of a tire inflation pressure gauge of an air hose,
e.g. gas station equipment, and the vehicle’s
control system can occur. Usually the readings
issued by the control system are more precise.
