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:

3Maximum tire inflation pressure

Warning
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.

You will not exceed the tire’s load carrying

Never exceed the maximum tire inflation
pressure. Follow recommended tire infla-
