9. Read the instructions provided with your child safety
seat or booster seat to make sure that you are using it
properly.
10. All occupants should wear their lap and shoulder
belts properly.
11. Position the driver seat and passenger seat as far
away from the instrument panel as practical to allow the
airbags room to inflate. Note that the power adjustable
pedals allow for more driver’s seat adjustment options.
Refer to “Adjustable Pedals” in Section 3 of this manual
for details.

How the Airbag System Works
•
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 “Airbag System Components,” except the
steering wheel and column and the knee bolsters.
•The ORC turns on the Airbag Warning
Light and Passenger Airbag Disable (PAD)
Indicator Light for six to eight seconds as a
self-check when the ignition is first turned
ON. After the self-check, the Airbag Warning Light
will turn off and the PAD Indicator Light will function
normally (Refer to “Passenger Airbag Disable (PAD)
Indicator Light” in this section). If the ORC detects a
malfunction in any part of the system, it turns on the
Airbag Warning Light either momentarily or continu-
ously. A single chime will sound if the light comes on
again after initial start up.
46 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system is not
operating properly. The TPMS malfunction indicator is
combined with the low tire pressure telltale.
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 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 onyour vehicle to ensure that the replacement or alternate
tires and wheels allow the TPMS to continue to function
properly.
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.
106 UNDERSTANDING YOUR INSTRUMENT PANEL

Rotate the tires “side-to-side” as shown in the diagram.
These effects can be reduced by timely rotation of tires.
The benefits of rotation are especially worthwhile with
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.Refer to the “Maintenance Schedules” in Section 8 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.
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.
168 STARTING AND OPERATING

TIRE PRESSURE MONITOR SYSTEM (TPMS)
Low Tire Indicator
If tire pressure falls below 23 psi (159 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
18 psi (124 kpa), the Low Tire Pressure Telltale will
illuminate, 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.

WARNING!
Do not exceed 55 mph (88 km/h) if the LOW Tire
indicator is activated. Vehicle handling and braking
may be reduced. You could have an accident and be
severely or fatally injured.
