How The Airbag System Works
²
TheOccupant Restraint Controller (ORC)determines
if a frontal collision is severe enough to require the
airbags to inflate. The airbag inflators are designed to
provide different rates of inflation. Based on the level
of collision severity, the ORC determines the proper
rate of inflation. The ORC may modify the rate of
passenger airbag inflation or prevent passenger airbag
deployment based on input from the Occupant Clas-
sification System (OCS). The ORC will not detect roll
over or rear impacts. Furthermore, the airbags are not
on and will not inflate if the key is in the OFF/LOCK
position, in the ACC position, or not in the ignition.
The ORC also monitors the readiness of the electronic
parts of the system whenever the ignition switch is in
the ON/RUN position. These include all of the items
listed under ªAirbag System Componentsº except the
steering wheel and column and the knee bolsters.

upon subsequent vehicle start-ups as long as the mal-
function exists. When the malfunction indicator is illumi-
nated, 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 malfunc-
tion 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. (See page 166 for more information.)CAUTION!
The Tire Pressure Monitor System (TPMS) has been
optimized for the original equipment tires and
wheels. The TPMS pressures have been established
for the tire size equipped on your vehicle. Undesir-
able 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 damage. Do not use aftermarket tire sealants
or balance beads if your vehicle is equipped with the
TPMS, as damage to the sensors may result.

aggressive tread designs such as those on all season type
tires. Rotation will increase tread life, help to maintain
mud, snow, and wet traction levels, and contribute to a
smooth, quiet ride.
Follow the ªMaintenance Schedulesº in Section 8 of this
manual for the recommended tire rotation frequency for
your type of driving. Remember, more frequent rotation is
permissible if desired. Also, correct for anything causing
rapid or unusual wear prior to performing the tire rotation.
Tire Rotation
Rotate the tires ªside-to-sideº as shown in the diagram.
NOTE:Each wheel on your vehicle contains a tire
pressure sensor. The Tire Pressure Monitor System
(TPMS) learns the location of each sensor though system
programming. Although not required, the manufacturer
recommends reprogramming the TPMS after rotating the
tires so that the system can relearn each sensor 's location.
See your authorized dealer for system reprogramming.

TIRE PRESSURE MONITOR SYSTEM (TPMS)
Low Tire Indicator
If tire pressure falls below 20 psi (138 kpa), the Low Tire
Pressure Telltale in the Message Center will illuminate, a
chime will sound, and the words LOW TIRE will flash
slowly in the Liquid Crystal Display (LCD) panel in the
bottom of the speedometer. If tire pressure falls below 14
psi (97 kpa), the Low Tire Pressure Telltale will illumi-
nate, a chime will sound, and the words FLAT TIRE will
flash rapidly in the display. You should obtain immediate
service if the low tire indicator is activated.
NOTE:Each wheel on your vehicle contains a tire
pressure sensor. The TPMS learns the location of each
sensor though system programming. Although not re-
quired, the manufacturer recommends reprogramming
the TPMS after rotating the tires so that the system can
relearn each sensor 's location. See your authorized dealer
for system reprogramming.
