Always adjust the tire inflation pressure ac-
cording to the tire and loading information
placard on the driver’s door B-pillar.
Underinflated tires wear excessively and/or
unevenly, adversely affect handling and fuel
economy, and are more likely to fail from be-
ing overheated.
Overinflated tires can adversely affect han-
dling and ride comfort, wear unevenly, in-
crease stopping distance, and result in
sudden deflation (blowout) because they are
more likely to become punctured or dam-
aged by road debris, potholes etc.
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
G
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recom-
mended by the vehicle manufacturer on the
vehicle placard or the tire inflation pressure
label. (If your vehicle has tires of a different
size than the size indicated on the vehicle
placard or 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 Monitor-
ing System (TPMS) that illuminates a low tire
pressure telltale when one or more of your
tires is significantly underinflated. Accord-
ingly, when the low tire pressure telltale illu-
minates, you should stop and check your
tires as soon as possible, and inflate them to
the proper pressure. Driving on a significant-
ly underinflated tire causes the tire to over-
heat 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 driv-
er’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.
USA only:
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-
function exists. When the malfunction
indicator is illuminated, the system may not
be able to detect or signal low tire pressure
as intended.

Reactivating Advanced TPMS
The TPMS must be reactivated when you
have adjusted the tire inflation pressure to
a new level (e.g. because of different load
or driving conditions). The TPMS is then
recalibrated to the current tire inflation
pressures.\1Using the tire and loading information
placard on the driver’s door B-pillar
(\2page 206), make sure the tire infla-
tion pressure of all four tires is correct.
\1Press buttonè orÿ on the mul-
tifunction steering wheel repeatedly
until the standard display menu ap-
pears in the multifunction display
(\2page 93).
TPMS malfunctions may occur for a variety
of reasons, including the installation of in-
compatible replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction telltale after replacing
one or more tires or wheels on your vehicle
to ensure that the replacement or alternate
tires and wheels allow the TPMS to continue
to function properly.iIf a condition causing the TPMS to mal-
function develops, it may take up to 10
minutes for the system to signal a mal-
function using the TPMS telltale flash-
ing and illumination sequence.
The telltale extinguishes after driving a
few minutes if the malfunction has
been corrected.
iOperating radio transmission equip-
ment (e.g. wireless headsets, two-way
radios) in or near the vehicle could
cause the TPMS to malfunctionWarning!
G
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.
iReactivate the TPMS after adjusting
the tire inflation pressure to the infla-
tion pressure recommended for the ve-
hicle operating condition. Tire pressure
should only be adjusted on cold tires.
Observe the recommended tire infla-
tion pressure on the tire and loading in-
formation placard on the driver’s door
B-pillar (\2page 206).

Potential problems associated with un-
derinflated and overinflated tires
Proper tire inflation pressure is essential to
the safe and satisfactory operation of your
vehicle. Three primary areas are affected
by improper tire inflation pressure:
1. Safety
2. Economy
Improper inflation pressures can cause un-
even wear patterns to develop across the
tire tread. These abnormal wear patterns
will reduce tread life resulting in a need for
earlier tire replacement. Underinflation
also increases tire rolling resistance and
results in higher fuel consumption.
Warning
G
Follow recommended tire inflation pres-
sures.
Do not underinflate tires. Underinflated tires
wear excessively and/or unevenly, adverse-
ly affect handling and fuel economy, and are
more likely to fail from being overheated.
Do not overinflate tires. Overinflated tires
can adversely affect handling and ride com-
fort, wear unevenly, increase stopping dis-
tance, and result in sudden deflation
(blowout) because they are more likely to
become punctured or damaged by road de-
bris, potholes etc.Warning
G
Improperly inflated tires are dangerous and
can cause accidents.
Unequal tire inflation pressures can cause
steering problems. You could lose control of
your vehicle.
Unequal tire inflation pressures from one
side of the vehicle to the other can cause
the vehicle to drift to the right or left. Always
drive with each tire inflated to the recom-
mended cold tire inflation pressure.

3. Ride comfort and vehicle stability
Proper tire inflation contributes to a com-
fortable ride. Overinflation produces a jar-
ring and uncomfortable ride.
Besides the tire name (sales designation)
and manufacturer's name, a number of
markings can be found on a tire.
Below are some explanations regarding
the markings on your vehicle’s tires:

For more information on tire load rating,
refer to "Tire size designation, load and
speed rating" (\2page 222).
For information on calculating total and
cargo load capacities, refer to "Tire and
loading information" (\2page 205). 1Maximum permissible tire inflation
pressure
This is the maximum permissible tire infla-
tion pressure for the tire.Always follow the recommended tire infla-
tion pressure (\2page 210) for proper tire
inflation.Warning
G
Do not overload the tires by exceeding the
specified load limit as indicated on the tire
and loading information placard on the driv-
er’s door B-pillar. Overloading the tires can
overheat them, possibly causing a blowout.
Overloading the tires can also result in han-
dling or steering problems, or brake failure.
Never overload them.
The vehicle maximum load on the tire must
not exceed the load carrying capacity of the
tire on your vehicle.
You will not exceed the tire’s load carrying
capacity if you adhere to the loading condi-
tions, tire size and cold tire inflation pres-
sures specified on the tire and loading
information placard.
