Tire Pressure Monitoring Low Pressure Warning

Should this occur, you should stop as soon as
possible and inflate the tires with low pres -
sure (those in a different color in the instru -
ment cluster graphic) to the vehicle’s
recommended cold placard pressure value.
Once the system receives the updated tire
pressures, the system will automatically
update, the pressure values in the graphic
display in the instrument cluster will return
to their original color, and the TPMS Warning
Light will turn off. NOTE:
When filling warm tires, the tire pressure
may need to be increased up to an additional
4 psi (28 kPa) above the recommended cold
placard pressure in order to turn the TPMS
Warning Light off.

The vehicle may need to be driven for up to
10 minutes above 15 mph (24 km/h) in order for
the TPMS to receive this information.
Service TPMS Warning
When a system fault is detected, the TPMS
Warning Light will flash on and off for 75
seconds and then remain on solid. The
system fault will also sound a chime. In addi
-
tion, the instrument cluster will display a
"SERVICE TIRE PRESSURE SYSTEM"
message for a minimum of five seconds and
then display dashes (--) in place of the pres -
sure value to indicate which sensor is not
being received. If the ignition is cycled, this sequence will
repeat, providing the system fault still exists.
If the system fault no longer exists, the
TPMS Warning Light will no longer flash, and
the “SERVICE TIRE PRESSURE SYSTEM”
message will no longer display, and a pres
-
sure value will display in place of the dashes.
A system fault can occur due to any of the
following:
Jamming due to electronic devices or
driving next to facilities emitting the same
radio frequencies as the TPMS sensors
Installing some form of aftermarket
window tinting that affects radio wave
signals
Lots of snow or ice around the wheels or
wheel housings
Using tire chains on the vehicle
Using wheels/tires not equipped with
TPMS sensors

3. If a child from 2 to 12 years old (not in arear-facing child restraint) must ride in
the front passenger seat, move the seat
as far back as possible and use the
proper child restraint. Refer to “Child
Restraints” in this section for further
information.
4. Never allow children to slide the shoulder belt behind them or under their arm.
5. You should read the instructions provided with your child restraint to make
sure that you are using it properly.
6. All occupants should always wear their lap and shoulder belts properly.
7. The driver and front passenger seats should be moved back as far as practical
to allow the front air bags room to inflate.
8. Do not lean against the door or window. If your vehicle has side air bags, and
deployment occurs, the side air bags will
inflate forcefully into the space between
occupants and the door and occupants
could be injured. 9. If the air bag system in this vehicle needs
to be modified to accommodate a
disabled person, refer to the “Customer
Assistance” section for customer service
contact information.
Seat Belt Systems
Buckle up even though you are an excellent
driver, even on short trips. Someone on the
road may be a poor driver and could cause a
collision that includes you. This can happen
far away from home or on your own street.
Research has shown that seat belts save
lives, and they can reduce the seriousness of
injuries in a collision. Some of the worst inju -
ries happen when people are thrown from the
vehicle. Seat belts reduce the possibility of
ejection and the risk of injury caused by
striking the inside of the vehicle. Everyone in
a motor vehicle should be belted at all times.
WARNING!

NEVER use a rearward facing child restraint
on a seat protected by an ACTIVE AIRBAG in
front of it, DEATH or SERIOUS INJURY to
the CHILD can occur.

It is advisable to always carry children in
a child restraint system on the rear seat,
which is the most protected position in
the event of a collision.
Should it be necessary to carry a child on
the passenger side front seat in a
rear-facing child restraint system, the
passenger side front air bag must be
deactivated. Always make sure the
airbag deactivation indicator light is illu -
minated when using a child restraint
system. The passenger seat must also be
positioned backward as far as possible to
avoid the child restraint system from
coming into contact with the dashboard.
A deploying passenger front air bag can
cause death or serious injury to a child
12 years or younger, including a child in
a rear-facing child restraint.

The SABs (if equipped with SABs) may help
to reduce the risk of occupant injury during
certain side impacts, in addition to the injury
reduction potential provided by the seat
belts and body structure.
When the SAB deploys, it opens the seam on
the outboard side of the seatback’s trim
cover. The inflating SAB deploys through the
seat seam into the space between the occu-
pant and the door. The SAB moves at a very
high speed and with such a high force that it
could injure occupants if they are not seated
properly, or if items are positioned in the
area where the SAB inflates. Children are at
an even greater risk of injury from a
deploying air bag. Side Impacts

The Side Air Bags are designed to activate in
certain side impacts. The Occupant Restraint
Controller (ORC) determines whether the
deployment of the Side Air Bags in a particular
impact event is appropriate, based on the
severity and type of collision. The side impact
sensors aid the ORC in determining the appro-
priate response to impact events. The system is
calibrated to deploy the Side Air Bags on the
impact side of the vehicle during impacts that
require Side Air Bag occupant protection. In
side impacts, the Side Air Bags deploy inde-
pendently; a left side impact deploys the left
Side Air Bags only and a right-side impact
deploys the right Side Air Bags only. Vehicle
damage by itself is not a good indicator of
whether or not Side Air Bags should have
deployed.

The Side Air Bags will not deploy in all side
collisions, including some collisions at
certain angles, or some side collisions that
do not impact the area of the passenger
compartment. The Side Air Bags may deploy
during angled or offset frontal collisions
where the front air bags deploy.Side Air Bags are a supplement to the seat
belt restraint system. Side Air Bags deploy in
less time than it takes to blink your eyes.
WARNING!
Do not use accessory seat covers or place
objects between you and the Side Air
Bags; the performance could be adversely
affected and/or objects could be pushed
into you, causing serious injury.
WARNING!
Occupants, including children, who are
up against or very close to Side Air Bags
can be seriously injured or killed. Occu
-
pants, including children, should never
lean on or sleep against the door, side
windows, or area where the side air bags
inflate, even if they are in an infant or
child restraint.

Seat belts (and child restraints where
appropriate) are necessary for your protec -
tion in all collisions. They also help keep
you in position, away from an inflating Side
Air Bag. To get the best protection from the
Side Air Bags, occupants must wear their
seat belts properly and sit upright with
their backs against the seats. Children
must be properly restrained in a child
restraint or booster seat that is appropriate
for the size of the child.

NOTE:
Air bag covers may not be obvious in the inte-
rior trim, but they will open during air bag
deployment.
Air Bag System Components
NOTE:
The Occupant Restraint Controller (ORC)
monitors the internal circuits and intercon -
necting wiring associated with electrical Air
Bag System Components listed below:
Occupant Restraint Controller (ORC)
Air Bag Warning Light
Steering Wheel and Column
Instrument Panel
Knee Impact Bolsters
Driver and Front Passenger Air Bags
Seat Belt Buckle Switch
Supplemental Side Air Bags
Front and Side Impact Sensors
Seat Belt Pretensioners
Seat Track Position Sensors
If A Deployment Occurs
The front air bags are designed to deflate
immediately after deployment.
NOTE:
Front and/or side air bags will not deploy in
all collisions. This does not mean something
is wrong with the air bag system.
If you do have a collision which deploys the
air bags, any or all of the following may
occur:
The air bag material may sometimes cause
abrasions and/or skin reddening to the
occupants as the air bags deploy and
unfold. The abrasions are similar to fric-
tion rope burns or those you might get
sliding along a carpet or gymnasium floor.
They are not caused by contact with chem -
icals. They are not permanent and
normally heal quickly. However, if you
haven’t healed significantly within a few
days, or if you have any blistering, see your
doctor immediately.
WARNING!
Side Air Bags need room to inflate. Do
not lean against the door or window. Sit
upright in the center of the seat.
Being too close to the Side Air Bags
during deployment could cause you to be
severely injured or killed.
Relying on the Side Air Bags alone could
lead to more severe injuries in a colli -
sion. The Side Air Bags work with your
seat belt to restrain you properly. In
some collisions, Side Air Bags won’t
deploy at all. Always wear your seat belt
even though you have Side Air Bags.

SAFETY TIPS
Transporting Passengers
NEVER TRANSPORT PASSENGERS IN THE
CARGO AREA.
Exhaust Gas The best protection against carbon monoxide
entry into the vehicle body is a properly
maintained engine exhaust system.
Whenever a change is noticed in the sound of
the exhaust system, when exhaust fumes can
be detected inside the vehicle, or when the
underside or rear of the vehicle is damaged,
have a competent mechanic inspect the
complete exhaust system and adjacent body
areas for broken, damaged, deteriorated, or
mispositioned parts. Open seams or loose
connections could permit exhaust fumes to
seep into the passenger compartment. In
addition, inspect the exhaust system each
time the vehicle is raised for lubrication or oil
change. Replace as required.
WARNING!
Do not leave children or animals inside
parked vehicles in hot weather. Interior
heat build-up may cause serious injury or
death.
It is extremely dangerous to ride in a
cargo area, inside or outside of a vehicle.
In a collision, people riding in these
areas are more likely to be seriously
injured or killed.
Do not allow people to ride in any area of
your vehicle that is not equipped with
seats and seat belts.
Be sure everyone in your vehicle is in a
seat and using a seat belt properly.
WARNING!
Exhaust gases can injure or kill. They
contain carbon monoxide (CO), which is
colorless and odorless. Breathing it can
make you unconscious and can eventually
poison you. To avoid breathing (CO), follow
these safety tips:

Do not run the engine in a closed garage or in
confined areas any longer than needed to
move your vehicle in or out of the area.
If you are required to drive with the trunk/lift-
gate/rear doors open, make sure that all
windows are closed and the climate control
BLOWER switch is set at high speed. DO NOT
use the recirculation mode.

If it is necessary to sit in a parked vehicle
with the engine running, adjust your
heating or cooling controls to force
outside air into the vehicle. Set the
blower at high speed.

transmission will automatically select
PARK and the engine will turn off,
however the ignition will remain in the
ACC mode (NOT the OFF mode). Never
leave a vehicle out of the PARK position,
or it could roll.

4. If the gear selector is in NEUTRAL, and the vehicle speed is below 5 mph (8 km/h),
pushing the ENGINE START/STOP button
once will turn the engine off. The ignition
will remain in the ACC mode.

5. If the vehicle speed is above 5 mph (8 km/h), the ENGINE START/STOP
button must be held for two seconds (or
three short pushes in a row) to turn the
engine off. The ignition will remain in the
ACC mode (NOT the OFF mode) if the
engine is turned off when the transmis -
sion is not in PARK.
WARNING!
When exiting the vehicle, always remove
the key fob from the ignition and lock
your vehicle.
Never leave children alone in a vehicle,
or with access to an unlocked vehicle.
Allowing children to be in a vehicle unat -
tended is dangerous for a number of
reasons. A child or others could be seri -
ously or fatally injured. Children should
be warned not to touch the parking
brake, brake pedal or the gear selector.
Do not leave the key fob in or near the
vehicle, or in a location accessible to

(Continued)
Ignition Park Interlock
This vehicle is equipped with an Ignition
Park Interlock which requires the transmis-
sion to be in PARK before the ignition can be
turned to the OFF mode. This helps the
driver avoid inadvertently leaving the vehicle
without placing the transmission in PARK.
This system also locks the transmission in
PARK whenever the ignition is in the OFF
mode. NOTE:
The transmission is NOT locked in PARK
when the ignition is in the ACC mode (even
though the engine will be off). Ensure that
the transmission is in PARK, and the ignition
is
OFF (not in ACC mode) before exiting the
vehicle.
Brake/Transmission Shift Interlock
System
This vehicle is equipped with a Brake Trans -
mission Shift Interlock system (BTSI) that
holds the transmission gear selector in PARK
unless the brakes are applied. To shift the
transmission out of PARK, the engine must
be running and the brake pedal must be
pressed. The brake pedal must also be
pressed to shift from NEUTRAL into DRIVE
or REVERSE when the vehicle is stopped or
moving at low speeds.
It is dangerous to shift out of PARK or
NEUTRAL if the engine speed is higher
than idle speed. If your foot is not firmly
pressing the brake pedal, the vehicle
could accelerate quickly forward or in
reverse. You could lose control of the
vehicle and hit someone or something.
Only shift into gear when the engine is
idling normally and your foot is firmly
pressing the brake pedal.
Unintended movement of a vehicle could
injure those in or near the vehicle. As
with all vehicles, you should never exit a
vehicle while the engine is running.
Before exiting a vehicle, always come to
a complete stop, then apply the parking
brake, shift the transmission into PARK,
and turn the ignition OFF. When the igni -
tion is in the OFF mode, the transmis-
sion is locked in PARK, securing the
vehicle against unwanted movement.
When exiting the vehicle, always make
sure the ignition is in the OFF mode,
remove the key fob from the vehicle, and
lock the vehicle.
WARNING! (Continued)
Never leave children alone in a vehicle,
or with access to an unlocked vehicle.
Allowing children to be in a vehicle unat -
tended is dangerous for a number of
reasons. A child or others could be seri -
ously or fatally injured. Children should
be warned not to touch the parking
brake, brake pedal or the transmission
gear selector.
Do not leave the key fob in or near the
vehicle (or in a location accessible to
children), and do not leave the ignition
in the ACC or ON/RUN mode. A child
could operate power windows, other
controls, or move the vehicle.
