If you have overfilled the tire, release tire
inflation 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.
X
Install the valve cap.

Repeat this procedure for each tire.
Tire Pressure Monitoring System
(TPMS), (USA only)
i
The Tire Pressure Monitoring System
(TPMS) is equipped with a combination low
tire pressure/TPMS malfunction telltale in
the instrument cluster. Depending on how
the telltale illuminates, it indicates a low
tire pressure condition or a malfunction in
the TPMS system itself:
R
If the telltale illuminates continuously,
one or more of your tires is significantly
underinflated. There is no malfunction in
the TPMS.
R
If the telltale flashes for 60 seconds and
then stays illuminated, the TPMS system
itself is not operating properly.
i
This device complies with Part 15 of the
FCC Rules. Operation is subject to the fol-
lowing two conditions:
1. This device may not cause harmful
interference, and
2. this device must accept any interfer-
ence received, including interference
that may cause undesired.
Any unauthorized modification to this
device could void the user’s authority to
operate the equipment.
The TPMS 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 warn-
ing is issued to alert you to a decrease in
pressure in one or more of the tires.
G
Warning!
The TPMS does not indicate a warning for
wrongly selected inflation pressures.
Always adjust tire inflation pressure
according to the Tire and Loading Informa-
tion placard or, if available, on the supple-
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.
G
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, and
inflate them to the proper pressure. Driving
on a significantly underinflated tire causes
