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.
X Repeat this procedure for each tire.
Tire Pressure Monitoring System
(TPMS)* Your vehicle may be equipped with a
Tire
Pressure Monitoring System (TPMS).
It monitors the tire inflation pressure in
all four tires. A warning is issued to alert
you to a decrease in pressure in one or more
of the tires.
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.
The TPMS only functions on wheels that are
equipped with the proper electronic sen-
sors. 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 Infor-
mation placard on the driver’s door B‑pil-
lar.
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 carefully applying the brakes and avoiding
abrupt steering maneuvers.
G
WARNING
Each tire should be checked monthly when
cold and inflated to the inflation pressure
recommended by the vehicle manufacturer
on the Tire and Loading Information plac-
ard. If your vehicle has tires of a different
size than the size indicated on the Tire and
Loading Information placard, you should
determine the proper tire inflation pres-
sure 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 is 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. Driv-
ing on a significantly underinflated tire
causes the tire to overheat and can lead to
tire failure.
Underinflation also increases energy con-
sumption, reduces tire tread life, and may
affect the vehicle’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.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS malfunction indicator is com-
bined with the low tire pressure telltale.
When the system detects a malfunction, the
telltale will flash for approximately
1 minute and then remain continuously
illuminated.
This sequence will continue upon subse-
quent vehicle start-ups as long as the mal- Tires and wheels

The combination low tire pressure/TPMS
malfunction telltale in the instrument
cluster (Y page 23) flashes for approx-
imately 5 seconds and then goes out.
After driving a few minutes the system
verifies that the current tire inflation
pressures are within the system’s speci-
fied range. Afterwards the current tire
inflation pressures are accepted as refer-
ence pressures and then monitored. Maximum tire inflation pressure
G
WARNING
Never exceed the max. tire inflation pres-
sure. Follow recommended tire inflation
pressures.
Do not underinflate tires. Underinflated
tires wear excessively and/or unevenly,
adversely affect handling and energy con-
sumption, and are more likely to fail from
being overheated.
Do not overinflate tires. Overinflated
tires can adversely affect handling and
ride comfort, wear unevenly, increase
stopping distance, and result in sudden
deflation (blowout) because they are more
likely to become punctured or damaged by
road debris, potholes etc. i
For illustration purposes only. Actual
data on tires are specific to each vehicle
and may vary from data shown in above
illustration.
This is the maximum permissible tire
inflation pressure 0043for the tire.
Always follow the recommended tire infla-
tion pressure (Y page 128) for proper tire
inflation. Loading the vehicle
Two labels on your vehicle show how much
weight it may properly carry.
1) The Tire and Loading Information plac- ard can be found on the driver’s door
B‑pillar. This placard tells you impor-
tant information about the number of
people that can be in the vehicle and
the total weight that can be carried in
the vehicle. It also contains informa-
tion on the proper size and recom-
mended tire inflation pressures for the
original equipment tires on your vehi-
cle.
2) The certification label, also found on the driver’s door B‑pillar, tells you
about the gross weight capacity of your
vehicle, called the Gross Vehicle
Weight Rating (GVWR). The GVWR
includes the weight of the vehicle, all
occupants, automotive fluids and
cargo. The certification label also
tells you about the front and rear axle
weight capacity, called the Gross Axle Tires and wheels

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 the tire to overheat and can lead to tire failure.
Underinflation also reduces fuel efficiency and tire tread life, and may affect the vehicle’s
handling and stopping ability. Please note that the TPMS is not a substitute for proper tire
