equipped with the Advanced Tire Pres-
sure Monitoring System.
iUSA only:
The Tire Pressure Monitoring System
(TPMS) is equipped with a combina-
tion low tire pressure/TPMS mal-
function telltale in the instrument
cluster (
\2
page 20). Depending on
how the telltale illuminates, it indi-
cates a low tire pressure condition or
a malfunction in the TPMS system it-
self:
If the telltale illuminates continuous-
ly, one or more of your tires is signif-
icantly underinflated. There is no
malfunction in the TPMS.

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 warning is issued to alert
you to a decrease in pressure in one or
more of the tires.
Tire pressure inquiries are made using
the multifunction display. The present
inflation pressures are displayed only af-
ter a few minutes’ travel time.

Press the
j
or
k
button until
the current inflation pressures for
each tire appear in the multifunction
display. If the telltale flashes for 60 seconds
and then stays illuminated, the TPMS
system itself is not operating proper-
ly.
iCanada only:
The Tire Pressure Monitoring System
(TPMS) is equipped with a low tire
pressure telltale in the instrument
cluster (
\2
page 20). If the telltale il-
luminates, one or more of your tires
is significantly underinflated.
iPossible differences between the
readings of a tire pressure gauge of
an air hose, e.g. gas station equip-
ment, and the vehicle’s control sys-
tem can occur. Usually the readings
issued by the control system are
more precise.

Warning
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.
iIf a spare wheel without wheel sen-
sors is mounted, the system may still
indicate the tire inflation pressure of
the removed wheel for some min-
utes. If this happens, keep in mind
that the indicated value where the
spare wheel is mounted does not re-
flect the actual spare tire inflation
pressure.

Warning
G
The TPMS does not warn you against in-
correctly selected tire inflation pressure
and does not warn you when the tire pres-
sure is not properly selected for the re-
spective vehicle load. It warns you only
when the pressure of one or more tires
decreases significantly below the refer-
ence inflation pressure which was stored
at the time of calibration of the TPMS af-
ter you inflated the tires.Always ensure that you recalibrate the
TPMS after you have inflated the tires to
the recommended cold inflation pressure.
Continued
Warning (Continued)
G
Always adjust the tire inflation pressure
according to the tire and loading informa-
tion 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 being overheated.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.
Continued
Warning (Continued)
G
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 ob-
ject). In this case bring the vehicle to a
halt by carefully 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 rec-
ommended 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 inflation pressure for those
tires).
Continued
Warning (Continued)
G
As an added safety feature, your vehicle
has been equipped with a Tire Pressure
Monitoring System (TPMS) that illumi-
nates a low tire pressure telltale when one
or more of your tires is significantly under-
inflated. Accordingly, when the low tire
pressure telltale illuminates, you should
stop and check your tires as soon as pos-
sible, and inflate them to the proper pres-
sure. Driving on a significantly
underinflated tire causes the tire to over-
heat and can lead to tire failure.
Continued
Warning (Continued)
G
Underinflation also reduces fuel efficiency
and tire tread life, and may affect the ve-
hicle’s handling and stopping ability.
Please note that the TPMS is not a substi-
tute for proper tire maintenance, and it is
the driver’s responsibility to maintain cor-
rect tire pressure, even if underinflation
has not reached the level to trigger illumi-
nation of the TPMS low tire pressure tell-
tale.

Reactivating the Advanced TPMSThe 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 in-
flation pressures.
\1
Make sure the tire inflation pressure
of all four tires is correct, using the
tire and loading information placard
1
or the tire inflation pressure placard
located on the driver’s door B-pillar
(
\2
page 362).
Warning!
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.
1. For vehicles with a gross weight capacity less
than 10 000 lbs (4 536 kg) (USA only).
iReactivate the TPMS after adjusting
the tire inflation pressure to the infla-
tion pressure recommended for the
vehicle operating condition. Tire in-
flation pressure should only be adju-
sted on cold tires. Observe the
recommended tire inflation pressure
on the tire and loading information
placard
1 or on the tire inflation pres-
sure placard on the driver’s door B-
pillar (\2
page 362).

Potential problems associated with
underinflated and overinflated tiresProper tire inflation pressure is essential
to the safe and satisfactory operation of
your vehicle. The following three primary
areas are affected by improper tire infla-
tion pressure:

1. Safety 2. Economy
Improper inflation pressures can cause
uneven wear patterns to develop across
the tire tread. These abnormal wear pat-
terns will reduce tread life resulting in a
need for earlier tire replacement. Under-
inflation also increases tire rolling resis-
tance 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, ad-
versely affect handling and fuel economy,
and are more likely to fail from being over-
heated.
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. Al-
ways drive with each tire inflated to the
recommended cold tire inflation pres-
sure.

3. Ride comfort and vehicle stabilityProper tire inflation contributes to a
comfortable ride. Overinflation produces
a jarring and uncomfortable ride.
Besides the tire name (sales designa-
tion) and manufacturer's name, a num-
ber of markings can be found on a tire.
Below are some explanations regarding
the markings on your vehicle’s tires:

G
Do not overload the tires by exceeding the
specified load limit as indicated on the
tire and loading information placard on
the driver’s door B-pillar. Overloading the
tires can overheat them, possibly causing
a blowout. Overloading the tires can also
result in handling or steering problems, or
brake failure.Never overload them.The vehicle maximum load on the tire
must not exceed the load carrying capac-
ity of the tire on your vehicle.
