proper pressure. Driving on a significantly under-
inflated tire causes the tire to overheat and can lead to
tire failure. Under-inflation also reduces fuel effi-
ciency 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 maintenance, and it is the driver ’s respon-
sibility to maintain correct tire pressure, even if
under-inflation 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 indi-
cator is combined with the low tire pressure telltale.
When the system detects a malfunction, the telltale
will flash for approximately one minute and then
remain continuously illuminated. This sequence will
continue upon subsequent vehicle start-ups as long
as the malfunction exists. When the malfunctionindicator is illuminated, the system may not be able
to detect or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of rea-
sons, including the installation of 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.
CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and

equipped on your vehicle. Undesirable system opera-
tion or sensor damage may result when using re-
placement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Using aftermarket tire sealants may
cause the Tire Pressure Monitoring System (TPMS)
sensor to become inoperable. After using an after-
market tire sealant it is recommended that you take
your vehicle to an authorized dealership to have your
sensor function checked.
•What To Do
Do not drive your vehicle with one or more tires
deflated because the driveability of the car could be
compromised. Stop the car and avoid braking and
sharp turns. Contact your authorized dealer as soon
as possible. ESC System
•What Does It MeanIntervention ESC System: The light will start
to flash as soon as the tires lose traction and
the ESC system becomes active. If the “ESC
Activation/Malfunction Indicator Light” be-
gins to flash during acceleration, ease up on
the accelerator and apply as little throttle as
possible. Be sure to adapt your speed and driving to the
prevailing road conditions.
Failure ESC System: If the light remains permanently
on after four second of the engine running, there may
be a failure in ESC system.
System Failure Hill Start Assist: The warning light comes
on to indicate a failure of the system Hill Start Assist.
• What To Do
Please contact your authorized dealer as soon as
possible.

some collisions, air bags won’t deploy at all. Al-
ways wear your seat belts even though you have air
bags.
Advanced Front Air Bag Operation
Advanced Front Air Bags are designed to provide addi-
tional protection by supplementing the seat belts. Ad-
vanced Front Air Bags are not expected to reduce the risk
of injury in rear, side, or rollover collisions. The Ad-
vanced Front Air Bags will not deploy in all frontal
collisions, including some that may produce substantial
vehicle damage — for example, some pole collisions,
truck underrides, and angle offset collisions.
On the other hand, depending on the type and location of
impact, Advanced Front Air Bags may deploy in crashes
with little vehicle front-end damage but that produce a
severe initial deceleration. Because air bag sensors measure vehicle deceleration
over time, vehicle speed and damage by themselves are
not good indicators of whether or not an air bag should
have deployed.
Seat belts are necessary for your protection in all colli-
sions, and also are needed to help keep you in position,
away from an inflating air bag.
When the ORC detects a collision requiring the Ad-
vanced Front Air Bags, it signals the inflator units. A large
quantity of non-toxic gas is generated to inflate the
Advanced Front Air Bags.
The steering wheel hub trim cover and the upper right
side of the instrument panel separate and fold out of the
way as the air bags inflate to their full size. The Advanced
Front Air Bags fully inflate in less time than it takes to
blink your eyes. The air bags then quickly deflate while
helping to restrain the driver and front passenger.

Additionally, on dry pavement under heavy throttle
input (where one may have no wheel spin), torque will be
sent to the rear in a pre-emptive effort to improve vehicle
launch and performance characteristics.
CAUTION!
All wheels must have the same size and type tires.
Unequal tire sizes must not be used. Unequal tire
size may cause failure of the power transfer unit.

306 STARTING AND OPERATING

The TPMS will continue to warn the driver of low tire
pressure as long as the condition exists, and will not turn
off until the tire pressure is at or above the recommended
cold tire pressure on the placard. Once the low tire
pressure warning (Tire Pressure Monitoring Telltale
Light) illuminates, you must increase the tire pressure to
the recommended cold tire pressure in order for the Tire
Pressure Monitoring Telltale Light to turn off. The system
will automatically update and the Tire Pressure Monitor-
ing Telltale Light will turn off once the system receives
the updated tire pressures. The vehicle may need to be
driven for up to 20 minutes above 15 mph (24 km/h) in
order for the TPMS to receive this information.
For example, your vehicle may have a recommended
cold (parked for more than three hours) tire pressure of
30 psi (207 kPa). If the ambient temperature is 68° F (20°
C) and the measured tire pressure is 27 psi (186 kPa), a
temperature drop to 20° F (-7° C) will decrease the tire
pressure to approximately 23 psi (159 kPa). This tirepressure is sufficiently low enough to turn on the Tire
Pressure Monitoring Telltale Light. Driving the vehicle
may cause the tire pressure to rise to approximately 27
psi (186 kPa), but the Tire Pressure Monitoring Telltale
Light will still be on. In this situation, the Tire Pressure
Monitoring Telltale Light will turn off only after the tires
are inflated to the vehicle’s recommended cold tire pres-
sure value.
CAUTION!

The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and

wear and correct cold tire inflation pressures. The manu-
facturer strongly recommends that you use tires equiva-
lent to the originals in size, quality and performance
when replacement is needed. Refer to the paragraph on
“Tread Wear Indicator”. Refer to the Tire and Loading
Information placard or the Vehicle Certification Label for
the size designation of your tire. The Load Index and
Speed Symbol for your tire will be found on the original
equipment tire sidewall. See the Tire Sizing Chart ex-
ample found in the “Tire Safety Information” section of
this manual for more information relating to the Load
Index and Speed Symbol of a tire.
It is recommended to replace the two front tires or two
rear tires as a pair. Replacing just one tire can seriously
affect your vehicle’s handling. If you ever replace a
wheel, make sure that the wheel’s specifications match
those of the original wheels.It is recommended you contact your authorized tire
dealer or original equipment dealer with any questions
you may have on tire specifications or capability. Failure
to use equivalent replacement tires may adversely affect
the safety, handling, and ride of your vehicle.
WARNING!
•
Do not use a tire, wheel size or rating other than
that specified for your vehicle. Some combinations
of unapproved tires and wheels may change sus-
pension dimensions and performance characteris-
tics, resulting in changes to steering, handling, and
braking of your vehicle. This can cause unpredict-
able handling and stress to steering and suspen-
sion components. You could lose control and have
a collision resulting in serious injury or death. Use
only the tire and wheel sizes with load ratings
approved for your vehicle.

STORING THE VEHICLE
If the vehicle should remain stationary for more than a
month, observe the following precautions:
•Park your vehicle in a covered, dry and possibly airy
location the windows open slightly;
• Check that the Electric Park Brake is not engaged.
• Disconnect the negative (-) terminal from the battery
post and be sure that the battery is fully charged.
During storage check battery charge quarterly.
• If you do not disconnect the battery from the electrical
system, check the battery charge every thirty days.
