Gas props support the liftgate in the open position.
However, because the gas pressure drops with tempera-
ture, it may be necessary to assist the props when
opening the liftgate in cold weather.
OCCUPANT RESTRAINTS
Some of the most important safety features in your
vehicle are the restraint systems:
•Three-point lap and shoulder belts for all seating
positions
•Advanced Front Airbags for driver and front passenger
•Supplemental Active Head Restraints (AHR) located
on top of the front seats (integrated into the head
restraint) — if equipped
•Supplemental Side Airbag Inflatable Curtains (SABIC)
that span the front, second, and third row seating for
the driver and passengers seated next to a window —
if equipped
•Supplemental Seat-Mounted Side Airbags (SAB) — if
equipped
•An energy-absorbing steering column and steering
wheel
•Knee bolsters/blockers for front seat occupants
•Front seat belts incorporate pretensioners to enhance
occupant protection by managing occupant energy
during an impact event — if equipped
If you will be carrying children too small for adult-sized
seat belts, the seat belts or the Lower Anchors and Tether
for CHildren (LATCH) feature can be used to hold infant
and child restraint systems. For more information on
LATCH, see Lower Anchors and Tether for CHildren
(LATCH).
52 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

WARNING!
Ignoring the Airbag Warning Light in your instru-
ment panel could mean you won’t have the airbags to
protect you in a collision. If the light does not come
on, stays on after you start the vehicle, or if it comes
on as you drive, have an authorized dealer service the
airbag system immediately.
Driver and Passenger Airbag Inflator Units
The Driver and Passenger Airbag Inflator Units are
located in the center of the steering wheel and the right
side of the instrument panel. When the ORC detects a
collision requiring the Advanced Front Airbags, it signals
the inflator units. A large quantity of non-toxic gas is
generated to inflate the Advanced Front Airbags. Differ-
ent airbag inflation rates are possible, based on the
collision type and severity. The steering wheel hub trim
cover and the upper right side of the instrument panelseparate and fold out of the way as the airbags inflate to
their full size. The airbags fully inflate in about 50 to 70
milliseconds. This is about half of the time it takes to
blink your eyes. The airbags then quickly deflate while
helping to restrain the driver and front passenger.
The Advanced Front Airbag gas is vented through the
vent holes in the sides of the airbag. In this way, the
airbags do not interfere with your control of the vehicle.
Supplemental Seat-Mounted Side Airbag Inflator
Units — If Equipped
The Side Impact (SRS) Seat-Mounted Side Airbags are
designed to activate only in certain side collisions.
The ORC determines if a side collision requires the side
airbags to inflate based on the severity and type of
collision.
Based on the severity and type of collision, the side
airbag inflator on the crash side of the vehicle may be

system detects a malfunction, the telltale will flash for
approximately one minute and then remain continuously
illuminated. This sequence will continue upon subse-
quent vehicle start-ups as long as the malfunction exists.
When the malfunction indicator is illuminated, the sys-
tem may not be able to detect or signal low tire pressure
as intended. TPMS malfunctions may occur for a variety
of reasons, 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
warning have been established for the tire size
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. Do not use tire sealant from a can, or
balance beads if your vehicle is equipped with a
TPMS, as damage to the sensors may result.

UNDERSTANDING YOUR INSTRUMENT PANEL 235

WARNING!
•The Anti-Lock Brake System contains sophisti-
cated electronic equipment that may be suscep-
tible to interference caused by improperly in-
stalled, or high output radio transmitting
equipment. This interference can cause possible
loss of anti-lock braking capability. Installation of
such equipment should be performed by qualified
professionals.
•Pumping of the Anti-Lock Brakes will diminish
their effectiveness and may lead to an accident.
Pumping makes the stopping distance longer. Just
press firmly on your brake pedal when you need
to slow down or stop.(Continued)
WARNING! (Continued)
•The Anti-Lock Brake System cannot prevent acci-
dents, including those resulting from excessive
speed in turns, following another vehicle too
closely, or hydroplaning. Only a safe, attentive,
and skillful driver can prevent accidents.
•The capabilities of an ABS-equipped vehicle must
never be exploited in a reckless or dangerous
manner, which could jeopardize the user ’s safety
or the safety of others.
All vehicle wheels and tires must be the same size and
type, and tires must be properly inflated to produce
accurate signals for the computer.
346 STARTING AND OPERATING

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
an accident resulting in serious injury or death.
Use only the tire and wheel sizes with load ratings
approved for your vehicle.
•Never use a tire with a smaller load index or
capacity, than what was originally equipped on
your vehicle. Using a tire with a smaller load index
could result in tire overloading and failure. You
could lose control and have an accident.(Continued)
WARNING! (Continued)
•Failure to equip your vehicle with tires having
adequate speed capability can result in sudden tire
failure and loss of vehicle control.
CAUTION!
Replacing original tires with tires of a different size
may result in false speedometer and odometer read-
ings.
SNOW TIRES
Some areas of the country require the use of snow tires
during Winter. Standard tires are of the all-season type
and satisfy this requirement as indicated by the M+S
designation on the tire sidewall.
368 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 recommended
cold tire placard pressure. Once the low tire pressure
warning has been illuminated, the tire pressure must be
increased to the recommended cold tire placard pressure
in order for the “TPMS Warning Lamp” to be turned off.
The system will automatically update and the “TPMS
Warning Lamp” will extinguish once the updated tire
pressures have been received. The vehicle may need to be
driven for up to 20 minutes above 15 mph (25 km/h) to
receive this information.
For example, your vehicle may have a recommended
cold (parked for more than three hours) tire pressure of
35 psi (241 kPa). If the ambient temperature is 68°F (20°C)
and the measured tire pressure is 30 psi (207 kPa), a
temperature drop to 20°F (-7°C) will decrease the tire
pressure to approximately 26 psi (179 kPa). This tire
pressure is sufficiently low enough to turn on the “TPMSWarning Light.” Driving the vehicle may cause the tire
pressure to rise to approximately 30 psi (207 kPa), but the
“TPMS Warning Light” will still be on. In this situation,
the “TPMS Warning Light” will turn off only after the
tires have been inflated to the vehicle’s recommended
cold tire pressure value.
CAUTION!
•The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures have
been established for the tire size equipped on your
vehicle. Undesirable system operation or sensor
damage may result when using replacement
equipment that is not of the same size, type, and/or
style. Aftermarket wheels can cause sensor dam-
age. Do not use aftermarket sealants or balance
beads if your vehicle is equipped with a TPMS, as
damage to the sensors may result.

•Month, Day and Hour of Manufacture (MDH)
The bar code allows a computer scanner to read the
Vehicle Identification Number (VIN).
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your vehicle.
This includes driver, passengers, and cargo. The total
load must be limited so that you do not exceed the
GVWR.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum capacity of the front and rear
axles. Distribute the load over the front and rear axles
evenly. Make sure that you do not exceed either front or
rear GAWR.
WARNING!
Because the front wheels drive and steer the vehicle,
it is important that you do not exceed the maximum
front or rear GAWR. A dangerous driving condition
can result if either rating is exceeded. You could lose
control of the vehicle and have an accident.
Tire Size
The tire size on the Vehicle Certification Label represents
the actual tire size on your vehicle. Replacement tires
must be equal to the load capacity of this tire size.
390 STARTING AND OPERATING

Rim Size
This is the rim size that is appropriate for the tire size
listed.
Inflation Pressure
This is the cold tire inflation pressure for your vehicle, for
all loading conditions up to full GAWR.
Curb Weight
The curb weight of a vehicle is defined as the total weight
of the vehicle with all fluids, including vehicle fuel, at full
capacity conditions, and with no occupants or cargo
loaded into the vehicle. The front and rear curb weight
values are determined by weighing your vehicle on a
commercial scale before any occupants or cargo are
added.
Overloading
The load carrying components (axle, springs, tires,
wheels, etc.) of your vehicle will provide satisfactory
service as long as you do not exceed the GVWR and front
and rear GAWR.
The best way to figure out the total weight of your
vehicle is to weigh it when it is fully loaded and ready for
operation. Weigh it on a commercial scale to ensure that
it is not over the GVWR.
Figure out the weight on the front and rear of the vehicle
separately. It is important that you distribute the load
evenly over the front and rear axles.
Overloading can cause potential safety hazards and
shorten useful service life. Heavier axles or suspension
components do not necessarily increase the vehicle’s
GVWR.

10. Lower the vehicle by turning the jack screw to the
left.
11. Finish tightening the lug nuts. Push down on the
wrench while tightening for increased leverage. Alternate
lug nuts until each nut has been tightened twice. The
correct wheel nut tightness is 95 ft lbs (130 N·m). If in
doubt about the correct tightness, have them checked
with a torque wrench by your authorized dealer or at a
service station.
12. Lower the jack to its fully-closed position.
WARNING!
A loose tire or jack thrown forward in a collision or
hard stop could endanger the occupants of the ve-
hicle. Always stow the jack parts and the spare tire in
the places provided. Have the deflated (flat) tire
repaired or replaced immediately.13. Place the deflated (flat) tire and compact spare tire
cover assembly. in the rear cargo area.
Do not stow the
deflated tire in the spare tire location. Have the full-
sized tire repaired or replaced, as soon as possible.
14. Stow the cable and wheel spacer before driving the
vehicle. Reassemble the winch handle extensions to form
a “T” and fit the winch “T” handle over the drive nut.
Rotate the nut to the right until the winch mechanism
clicks at least three times.
15. Stow the jack, jack handle and winch handle tools.
16. Check the compact spare tire pressure as soon as
possible. Correct the tire pressure, as required.Wheel Nuts
All wheel nuts should be tightened occasionally, to
eliminate the possibility of wheel studs being sheared or
the bolt holes in the wheels becoming elongated. This is
especially important during the first few hundred miles
