SUPPLEMENTAL RESTRAINT SYSTEM (SRS) —
AIR BAGS
Air Bag System Components
Your vehicle may be equipped with the following air bag system components:
• Occupant Restraint Controller (ORC)
• Air Bag Warning Light
• Steering Wheel and Column
• Instrument Panel
• Knee Impact Bolsters
• Advanced Front Air Bags
• Supplemental Side Air Bags
• Front and Side Impact Sensors
• Seat Belt Pretenioners
• Seat Belt Buckle Switch
• Seat Track Position Sensors
Advanced Front Air Bags
• This vehicle has Advanced Front Air Bags for both the driver and front passenger
as a supplement to the seat belt restraint systems. The Advanced Front Air Bags
will not deploy in every type of collision.
• Advanced Front Air Bags are designed to provide additional protection by
supplementing the seat belts. Advanced Front Air Bags are not expected to reduce
the risk of injury in rear, side, or rollover collisions.
• The Advanced 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 collisions, and also are needed
to help keep you in position, away from an inflating air bag.
• The air bags must be ready to inflate for your protection in a collision. The
Occupant Restraint Controller (ORC) monitors the internal circuits and intercon-
necting wiring associated with air bag system electrical components.
GETTING STARTED
14

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 malfunction
indicator 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 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.
NOTE:
Tire pressures change by approximately 1 psi (7 kPa) per 12° F (7° C) of air
temperature change. Keep this in mind when checking tire pressure inside a garage,
especially in the Winter. Example: If garage temperature is 68°F (20°C), and the
outside temperature is 32°F (0°C), then the cold tire inflation pressure should be
increased by 3 psi (21 kPa), which equals 1 psi (7 kPa) for every 12°F (7°C) for this
outside temperature condition.
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 operation or sensor damage may result when using
replacement equipment that is not of the same size, type, and/or style. Aftermar-
ket 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.
- Brake Warning Light
This light monitors various brake functions, including brake fluid level and parking
brake application. If the brake light turns on, it may indicate that the parking brake
is applied, that the brake fluid level is low, or that there is a problem with the
anti-lock brake system reservoir.
If the light remains on when the parking brake has been disengaged, and the fluid
level is at the full mark on the master cylinder reservoir, it indicates a possible brake
hydraulic system malfunction or that a problem with the Brake Booster has been
detected by the Anti-Lock Brake System (ABS)/Electronic Stability Control (ESC)
system. In this case, the light will remain on until the condition has been corrected.
If the problem is related to the brake booster, the ABS pump will run when applying
the brake, and a brake pedal pulsation may be felt during each stop.
The dual brake system provides a reserve braking capacity in the event of a failure to
a portion of the hydraulic system. A leak in either half of the dual brake system is
indicated by the Brake Warning Light, which will turn on when the brake fluid level
in the master cylinder has dropped below a specified level. The light will remain on
until the cause is corrected.
