display dashes (- -) in place of the pressure value to
indicate which sensor is not being received.
If the ignition switch is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault no
longer exists, the TPM Telltale Light will no longer flash,
and theService Tire Pressure System message will no
longer display, and a pressure value will display in place of
the dashes. A system fault can occur due to any of the
following:
• Signal interference due to electronic devices or driving
next to facilities emitting the same radio frequencies as
the TPM sensors.
• Installing aftermarket window tinting that contains ma-
terials that may block radio wave signals.
• Accumulation of snow or ice around the wheels or
wheel housings.
• Using tire chains on the vehicle.
• Using wheels/tires not equipped with TPM sensors. Vehicles With Compact Spare
1. The compact spare tire or non-matching full size does
not have a tire pressure monitoring sensor. Therefore,
the TPMS will not monitor the pressure in the compact
spare tire.
2. If you install the compact or non-matching full size spare tire in place of a road tire that has a pressure below
the low-pressure warning limit, upon the next ignition
key cycle, the “TPMS Telltale Light” will remain on and
a chime will sound. In addition, the graphic in the
instrument cluster will still display a different color
pressure value and an Inflate to XXmessage.
3. After driving the vehicle for up to 20 minutes above 15 mph (24 km/h), the “TPMS Telltale Light” will flash
on and off for 75 seconds and then remain on solid. In
addition, the instrument cluster will display a “Service
Tire Pressure System” message for five seconds and then
display dashes (- -) in place of the pressure value.
4. For each subsequent ignition key cycle, a chime will sound, the “TPMS Telltale Light” will flash on and off
for 75 seconds and then remain on solid, and the
instrument cluster will display a “Service Tire Pressure
164 SAFETY

System” message for five seconds and then display
dashes (- -) in place of the pressure value.
5. Once you repair or replace the original road tire and reinstall it on the vehicle in place of the compact spare or
non-matching full size, the TPMS will update automati-
cally. In addition, the “TPMS Telltale Light” will turn off
and the graphic in the instrument cluster will display a
new pressure value instead of dashes (- -), as long as no
tire pressure is below the low-pressure warning limit in
any of the four active road tires. The vehicle may need to
be driven for up to 20 minutes above 15 mph (24 km/h)
in order for the TPMS to receive this information.
TPMS Deactivation — If Equipped
The TPMS can be deactivated if replacing all four wheel
and tire assemblies (road tires) with wheel and tire assem-
blies that do not have TPMS Sensors, such as when
installing winter wheel and tire assemblies on your vehicle.
To deactivate the TPMS, first replace all four wheel and tire
assemblies (road tires) with tires not equipped with Tire
Pressure Monitoring (TPM) Sensors. Then, drive the ve-
hicle for 20 minutes above 15 mph (24 km/h). The TPMS will chime, the Tire Pressure Monitoring System Warning
Light will flash on and off for 75 seconds and then remain
on. The instrument cluster will display the “Service Tire
Pressure System” message and then display dashes (--) in
place of the pressure values.
Beginning with the next ignition cycle, the TPMS will no
longer chime or display the “Service Tire Pressure System”
message in the instrument cluster but dashes (--) will
remain in place of the pressure values.
To reactivate the TPMS, replace all four wheel and tire
assemblies (road tires) with tires equipped with TPM
sensors. Then, drive the vehicle for up to 20 minutes above
15 mph (24 km/h). The TPMS will chime, the Tire Pressure
Monitoring System Warning Light will flash on and off for
75 seconds and then turn off. The instrument cluster will
display the “Service Tire Pressure System” message and
then display pressure values in place of the dashes. On the
next ignition cycle the
Service Tire Pressure System
message will no longer be displayed as long as no system
fault exists.

Enhanced Seat Belt Use Reminder System (BeltAlert)
Driver and Passenger BeltAlert (if equipped)
BeltAlert is a feature intended to remind the driver
and outboard front seat passenger (if equipped with
outboard front passenger seat BeltAlert) to buckle their
seat belts. The Belt Alert feature is active whenever the
ignition switch is in the START or ON/RUN position.
Initial Indication
If the driver is unbuckled when the ignition switch is first
in the START or ON/RUN position, a chime will signal for
a few seconds. If the driver or outboard front seat passen-
ger (if equipped with outboard front passenger seat
BeltAlert) is unbuckled when the ignition switch is first in
the START or ON/RUN position the Seat Belt Reminder
Light will turn on and remain on until both outboard front
seat belts are buckled. The outboard front passenger seat
BeltAlert is not active when an outboard front passenger
seat is unoccupied.
BeltAlert Warning Sequence
The BeltAlert warning sequence is activated when the
vehicle is moving above a specified vehicle speed range
and the driver or outboard front seat passenger is unbuck-
led (if equipped with outboard front passenger seat BeltAlert) (the outboard front passenger seat BeltAlert is
not active when the outboard front passenger seat is
unoccupied). The BeltAlert warning sequence starts by
blinking the Seat Belt Reminder Light and sounding an
intermittent chime. Once the BeltAlert warning sequence
has completed, the Seat Belt Reminder Light will remain on
until the seat belts are buckled. The BeltAlert warning
sequence may repeat based on vehicle speed until the
driver and occupied outboard front seat passenger seat
belts are buckled. The driver should instruct all occupants
to buckle their seat belts.
Change of Status
If the driver or outboard front seat passenger (if equipped
with outboard front passenger seat BeltAlert) unbuckles
their seat belt while the vehicle is traveling, the BeltAlert
warning sequence will begin until the seat belts are buck-
led again.
The outboard front passenger seat BeltAlert is not active
when the outboard front passenger seat is unoccupied.
BeltAlert may be triggered when an animal or other items
are placed on the outboard front passenger seat or when
the seat is folded flat (if equipped). It is recommended that
pets be restrained in the rear seat (if equipped) in pet
harnesses or pet carriers that are secured by seat belts, and
cargo is properly stowed.
168 SAFETY

The air bag system must be ready to protect you in a
collision. The Occupant Restraint Controller (ORC) moni-
tors the internal circuits and interconnecting wiring asso-
ciated with the electrical Air Bag System Components.
Your vehicle may be equipped with the following Air Bag
System Components:
Air Bag System Components
•Occupant Restraint Controller (ORC)
• Air Bag Warning Light
•Steering Wheel and Column
• Instrument Panel
• Knee Impact Bolsters
• Driver and Front Passenger Air Bags
• Seat Belt Buckle Switch
• Supplemental Side Air Bags
• Supplemental Knee Air Bags
• Front and Side Impact Sensors
• Seat Belt Pretensioners
• Seat Track Position Sensors
Air Bag Warning Light
The ORC monitors the readiness of the electronic parts of
the air bag system whenever the ignition switch
is in the START or ON/RUN position. If the
ignition switch is in the OFF position or in the
ACC position, the air bag system is not on and
the air bags will not inflate.
The ORC contains a backup power supply system that may
deploy the air bag system even if the battery loses power or
it becomes disconnected prior to deployment.
The ORC turns on the Air Bag Warning Light in the
instrument panel for approximately four to eight seconds
for a self-check when the ignition switch is first in the
ON/RUN position. After the self-check, the Air Bag Warn-
ing Light will turn off. If the ORC detects a malfunction in
any part of the system, it turns on the Air Bag Warning
Light, either momentarily or continuously. A single chime
will sound to alert you if the light comes on again after
initial startup.
The ORC also includes diagnostics that will illuminate the
instrument panel Air Bag Warning Light if a malfunction is
detected that could affect the air bag system. The diagnos-
tics also record the nature of the malfunction. While the air
178 SAFETY

bag system is designed to be maintenance free, if any of the
following occurs, have an authorized dealer service the air
bag system immediately.
•The Air Bag Warning Light does not come on during the
four to eight seconds when the ignition switch is first in
the ON/RUN position.
• The Air Bag Warning Light remains on after the four to
eight-second interval.
• The Air Bag Warning Light comes on intermittently or
remains on while driving.
NOTE: If the speedometer, tachometer, or any engine
related gauges are not working, the Occupant Restraint
Controller (ORC) may also be disabled. In this condition
the air bags may not be ready to inflate for your protection.
Have an authorized dealer service the air bag system
immediately.WARNING!
Ignoring the Air Bag Warning Light in your instrument
panel could mean you won’t have the air bag system to
protect you in a collision. If the light does not come on
as a bulb check when the ignition is first turned on,
stays on after you start the vehicle, or if it comes on as
you drive, have an authorized dealer service the air bag
system immediately.
Redundant Air Bag Warning Light
If a fault with the Air Bag Warning Light is detected, which could affect the Supplemental Restraint System
(SRS), the Redundant Air Bag Warning Light will
illuminate on the instrument panel. The Redun-
dant Air Bag Warning Light will stay on until the
fault is cleared. In addition, a single chime will sound to
alert you that the Redundant Air Bag Warning Light has
come on and a fault has been detected. If the Redundant
Air Bag Warning Light comes on intermittently or remains
on while driving have an authorized dealer service the
vehicle immediately.
