mental tire inflation pressure information
on the inside of the fuel filler flap.
The TPMS is not able to issue a warning due
to a sudden dramatic loss of pressure (e.g.
tire blowout caused by a foreign object). In
this case bring the vehicle to a halt by care-
fully applying the brakes and avoiding
abrupt steering maneuvers.

Warning!
Each tire, including the spare (if provided),
should be checked every other week when
cold and inflated to the inflation pressure
recommended by the vehicle manufacturer
on the Tire and Loading Information placard
on the driver’s door B-pillar or, if available,
the tire inflation pressure label on the inside
of the fuel filler flap. If your vehicle has tires
of a different size than the size indicated on
the Tire and Loading Information placard or,
if available, the tire inflation pressure label,
you should determine the proper tire infla-
tion pressure for those tires.
As an added safety feature, your vehicle has
been equipped with a tire pressure moni-
toring system (TPMS) that illuminates a low
tire pressure telltale when one or more of
your tires are significantly underinflated.
Accordingly, when the low tire pressure
telltale illuminates, you should stop and
check your tires as soon as possible. Driv-
ing on a significantly underinflated tire
causes the tire to overheat and can lead to
tire failure.
Underinflation also reduces fuel efficiency
and tire tread life, and may affect the vehi-
cle’s handling and stopping ability. Please
note that the TPMS is not a substitute for
proper tire maintenance, and it is the
driver’s responsibility to maintain correct
tire pressure, even if underinflation has not
reached the level to trigger illumination of
the TPMS low tire pressure telltale.
Tire pressure inquiries are made using the
multifunction display. The present inflation
pressures are displayed only after a few
minutes’ travel time.

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

Press button è or ÿ on the multi-
function steering wheel repeatedly until the
standard display appears in the multifunc-
tion display (Y page 129).
X
Press button j or k until the current
inflation pressures for each tire appear in
the multifunction display.

When the vehicle has been parked for lon-
ger than 20 minutes, the message appears
in the multifunction display.
G
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.

With a spare wheel mounted, the system
may still indicate the tire inflation pressure
of the removed road wheel for some
minutes. If this happens, keep in mind that
