are possible, based on the collision type and severity. 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 air bags fully
inflate in about 50 to 70 milliseconds. This is about half of
the time it takes to blink your eyes. The air bags then
quickly deflate while helping to restrain the driver and
front passenger.
The Advanced Front Air Bag gas is vented through the
vent holes in the sides of the air bag. In this way, the air
bags do not interfere with your control of the vehicle.
Supplemental Driver Side Knee Air Bag Inflator
Unit
The Supplemental Driver Side Knee Air Bag unit is
located in the instrument panel trim beneath the steering
column. When the ORC detects a collision requiring the
air bag, it signals the inflator units. A large quantity of
non-toxic gas is generated to inflate the SupplementalDriver Side Knee Air Bag. The trim cover separates and
folds out of the way allowing the air bag to inflate to the
full size. The air bag fully inflates in about 15 to 20
milliseconds. The Supplemental Driver Side Knee Air
Bag gas is vented through small vent holes in the side of
the air bag.
Supplemental Seat-Mounted Side Air Bag (SAB)
Inflator Units
The Supplemental Seat-Mounted Side Air Bags (SAB) are
designed to activate only in certain side collisions.
The ORC determines if a side collision requires the side
air bags to inflate, based on the severity and type of
collision.
Based on the severity and type of collision, the side air
bag inflator on the crash side of the vehicle may be
triggered, releasing a quantity of non-toxic gas. The
inflating SAB exits through the seat seam into the space
between the occupant and the door. The SAB fully inflate

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 49

WARNING! (Continued)
•Never put floor mats or other floor coverings on
top of already installed floor mats. Additional
floor mats and other coverings will reduce the size
of the pedal area and interfere with the pedals.
•Check mounting of mats on a regular basis. Al-
ways properly reinstall and secure floor mats that
have been removed for cleaning.
•Always make sure that objects cannot fall into the
driver footwell while the vehicle is moving. Ob-
jects can become trapped under the brake pedal
and accelerator pedal causing a loss of vehicle
control.
•If required, mounting posts must be properly
installed, if not equipped from the factory.(Continued)
WARNING! (Continued)
Failure to properly follow floor mat installation or
mounting can cause interference with the brake
pedal and accelerator pedal operation causing loss of
control of the vehicle.
Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread or sidewall. Inspect the tread for cuts
and cracks. Inspect sidewalls for cuts, cracks and bulges.
Check the wheel bolts for tightness. Check the tires
(including spare) for proper cold inflation pressure.

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.
16. Automatic Gearbox Failure This light will illuminate when there is an
automatic transmission fault. 17. Oil Pressure Warning Light
This light indicates low engine oil pressure. The
light should turn on momentarily when the engine
is started. If the light turns on while driving, stop the
vehicle and shut off the engine as soon as possible. A
chime will sound for four minutes when this light turns
on.
Do not operate the vehicle until the cause is corrected.
This light does not indicate how much oil is in the engine.
The engine oil level must be checked under the hood.
18. Malfunction Indicator Light (MIL) The Malfunction Indicator Light (MIL) is part of
an onboard diagnostic system, called OBDII, that
monitors engine and automatic transmission con-
trol systems. The light will illuminate when the key is in
the ON/RUN position before engine start. If the bulb
does not come on when turning the key from OFF/LOCK
to ON/RUN, have the condition checked promptly.

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 other 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.
TIRE CHAINS
Use only compact chains, or other traction aids that meet
SAE type “Class S” specifications. Chains must be the
proper size for the vehicle, as recommended by the chain
manufacturer.
NOTE:Do not use tire chains on a compact spare tire.

STARTING AND OPERATING 253

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 26 psi (179 kPa). This tire
pressure 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
warnings have been established for the tire size
equipped on your vehicle. Undesirable system
operation or sensor damage may result when us-
ing replacement equipment that is not of the same
size, type, and/or style. Aftermarket wheels can
cause sensor damage. Do not use aftermarket tire
sealants or balance beads if your vehicle is
equipped with a TPMS, as damage to the sensors
may result.
•After inspecting or adjusting the tire pressure,
always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the valve
stem, which could damage the Tire Pressure Moni-
toring Sensor.
