Operation
Tires and wheels
Checking tire inflation pressure
electronically
The tire inflation pressure monitor only
functions on wheels that are equipped with
the proper electronic sensors. It monitors
the tire inflation pressure, as selected by
the driver, in all four tires. A warning is is-
sued 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
(
୴ page 117). The present inflation pres-
sures are displayed only after a few min-
utes travel time.
̈ Switch on the ignition ( ୴ page 40).
̈ Make sure you are viewing the stan-
dard display menu (
୴ page 117).
̈ Press k button until the current in-
flation pressures for each tire appear in
the tachometer display field.

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

You can select the unit of measure
(bar/psi) used for the tire inflation
pressure by changing the setting in the
control system (
୴ page 136).
Warning!
G
When the tire inflation pressure monitoring
system warning light is lit, one or more of
your tires is significantly under-inflated. You
should stop and check your tires as soon as
possible, and inflate them to the proper tire
inflation pressure as indicated on the vehi-
cle’s tire information placard. Driving on a
significantly under-inflated tire causes the
tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency
and tire tread life, and may affect the vehi-
cle’s handling and stopping ability. Each tire,
including the spare, should be checked
monthly when cold and set to the recom-
mended tire inflation pressure as specified
in the vehicle placard and owner’s manual. ୴୴
