will flash on and off for 75 seconds and then remain on
solid. For each subsequent ignition key cycle, a chime
will sound and the “Tire Pressure Monitoring Telltale
Light” will flash on and off for 75 seconds and then
remain on solid. Once you repair or replace the original
road tire, and reinstall it on the vehicle in place of the
spare tire, the TPMS will update automatically and the
“Tire Pressure Monitoring Telltale Light” will turn OFF,
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.
Premium System — If Equipped
The Tire Pressure Monitor System (TPMS) uses wireless
technology with wheel rim-mounted electronic sensors to
monitor tire pressure levels. Sensors, mounted to each
wheel as part of the valve stem, transmit tire pressure
readings to the Receiver Module.NOTE:
It is particularly important, for you to regularly
check the tire pressure in all of your tires and to maintain
the proper pressure.

SAFETY 231

The Tire Pressure Monitor System (TPMS) consists of the
following components:
•Receiver Module
• Four Tire Pressure Monitoring Sensors
• Various Tire Pressure Monitoring System Messages,
which display in the instrument cluster, and a graphic
displaying tire pressures
• Tire Pressure Monitoring Telltale Light
A tire pressure monitoring sensor is located in the spare
wheel, if the vehicle is equipped with a matching full-size
spare wheel and tire assembly. The matching full-size spare
tire can be used in place of any of the four road tires.
Tire Pressure Monitoring Low Pressure Warnings
The Tire Pressure Monitoring Telltale Light will illu-
minate in the instrument cluster, and an audible
chime will be activated, when one or more of the four active
road tire pressures are low. In addition, the instrument
cluster will display a “LOW TIRE” message for a minimum
of five seconds. An “Inflate to XX” message and a graphic display of the pressure value(s) with the low tire(s) high-
lighted or in a different color will also be displayed. Refer to
“Instrument Cluster Display” in “Getting To Know Your
Instrument Panel” for further information.
NOTE:
Your system can be set to display pressure units in
PSI, kPa, or BAR.
Tire Pressure Monitor Display
232 SAFETY

Should a low tire condition occur on any of the four active
road tire(s), you should stop as soon as possible, and inflate
the low tire(s) that is highlighted or shown in a different
color on the graphic display to the vehicle’s recommended
cold tire pressure inflation value shown in the “Inflate to
XX” message. The system will automatically update, the
graphic display of the pressure value(s) will no longer be
highlighted or shown in a different color and the Tire
Pressure Monitoring Telltale Light will extinguish once the
updated tire pressure(s) have been received.
NOTE:When filling warm tires, the tire pressure may need
to be increased up to an additional 4 psi (30 kPa) above the
recommended cold placard pressure in order to turn the
Tire Pressure Monitoring Telltale Light off.
The vehicle may need to be driven for up to 20 minutes
above 15 mph (24 km/h) to receive this information.
Service TPM System Warning
The “Tire Pressure Monitoring Telltale Light” will flash on
and off for 75 seconds, and remain on solid when a system
fault is detected. The system fault will also sound a chime.
The instrument cluster will display a “SERVICE TPM
SYSTEM” message for a minimum of five seconds. This
message is then followed by a graphic display, with “- -“ in place of the pressure value(s), indicating which Tire Pres-
sure Monitoring Sensor(s) 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 “Tire Pressure Monitoring Telltale Light”
will no longer flash, the
SERVICE TPM SYSTEM message
will not be present, and a pressure value will be displayed
instead of dashes. A system fault can occur by any of the
following:
• Jamming due to electronic devices or driving next to
facilities emitting the same Radio Frequencies as the
TPM sensors.
• Installing some form of aftermarket window tinting that
affects radio wave signals.
• Lots of snow or ice around the wheels or wheel hous-
ings.
• Using tire chains on the vehicle.
• Using wheels/tires not equipped with TPM sensors.

SAFETY 233

NOTE:
•If your vehicle is equipped with a matching full-size
spare wheel and tire assembly, it has a tire pressure
monitoring sensor, and can be monitored by the Tire
Pressure Monitoring System (TPMS) when swapped
with a low pressure road tire. In the event that the
matching full-size spare tire is swapped with a low
pressure road tire, the next ignition switch cycle will still
show the “Tire Pressure Monitoring Telltale Light” to be
ON, a chime to sound, a “LOW TIRE” message to
appear in the instrument cluster, and the graphic display
will still show the Inflate to XXmessage and the low
tire pressure value highlighted or shown in a different
color. Driving the vehicle for up to 20 minutes above
15 mph (24 km/h) will turn OFF the “Tire Pressure
Monitoring Telltale Light” as long as none of road tires
are below the low pressure warning threshold.
• If your vehicle is not equipped with a matching full-size
spare wheel and tire assembly, it does not have a tire
pressure monitoring sensor in the spare tire. The TPMS
will not be able to monitor the tire pressure. If you install
the spare tire in place of a road tire that has a pressure
below the low-pressure warning limit, upon the next
ignition switch cycle, the “Tire Pressure Monitoring Telltale Light” will remain ON, a chime will sound, and
the instrument cluster will still display the
Inflate to XX
message and a highlighted or different color pressure
value in the graphic display. After driving the vehicle for
up to 20 minutes above 15 mph (24 km/h), the “Tire
Pressure Monitoring Telltale Light” will flash on and off
for 75 seconds and then remain on solid. In addition, the
instrument cluster will display a “SERVICE TPM SYS-
TEM message for a minimum of five seconds and then
display dashes (- -) in place of the pressure value. For
each subsequent ignition switch cycle, a chime will
sound, the “Tire Pressure Monitoring Telltale Light” will
flash on and off for 75 seconds and then remain on solid,
and the instrument cluster will display a SERVICE TPM
SYSTEM message for a minimum of five seconds and
then display dashes (- -) in place of the pressure value.
• Once you repair or replace the original road tire, and
reinstall it on the vehicle in place of the spare tire, the
TPMS will update automatically.
In addition, the “Tire Pressure Monitoring 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
234 SAFETY

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
vehicle for 10 minutes above 15 mph (24 km/h). The TPMS
will chime, theTPM Telltale Light will flash on and off for
75 seconds and then remain on. The instrument cluster will
display the “SERVICE TPM 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 TPM 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 10 minutes above
15 mph (24 km/h). The TPMS will chime, the TPM TelltaleLight
will flash on and off for 75 seconds and then turn off.
The instrument cluster will display the “SERVICE TPM
SYSTEM” message and then display pressure values in
place of the dashes. On the next ignition cycle the SER-
VICE TPM SYSTEM message will no longer be displayed
as long as no system fault exists.

Supplemental Restraint Systems (SRS)
Some of the safety features described in this section may be
standard equipment on some models, or may be optional
equipment on others. If you are not sure, ask your autho-
rized dealer.
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

248 SAFETY

WARNING!
•Being too close to the steering wheel or instrument
panel during front air bag deployment could cause
serious injury, including death. Air bags need room
to inflate. Sit back, comfortably extending your arms
to reach the steering wheel or instrument panel.
•
Never place a rear-facing child restraint in front of an
air bag. A deploying passenger front air bag can cause
death or serious injury to a child 12 years or younger,
including a child in a rear-facing child restraint.
• Only use a rear-facing child restraint in a vehicle
with a rear seat.
Driver And Passenger Front Air Bag Features
The Advanced Front Air Bag system has multistage driver
and front passenger air bags. This system provides output
appropriate to the severity and type of collision as deter-
mined by the Occupant Restraint Controller (ORC), which
may receive information from the front impact sensors (if
equipped) or other system components.
The first stage inflator is triggered immediately during an
impact that requires air bag deployment. A low energy
output is used in less severe collisions. A higher energy
output is used for more severe collisions. This vehicle may be equipped with a driver and/or front
passenger seat belt buckle switch that detects whether the
driver or front passenger seat belt is buckled. The seat belt
buckle switch may adjust the inflation rate of the Ad-
vanced Front Air Bags.
This vehicle may be equipped with driver and/or front
passenger seat track position sensors that may adjust the
inflation rate of the Advanced Front Air Bags based upon
seat position.
WARNING!
•
No objects should be placed over or near the air bag
on the instrument panel or steering wheel because
any such objects could cause harm if the vehicle is in
a collision severe enough to cause the air bag to
inflate.
• Do not put anything on or around the air bag covers
or attempt to open them manually. You may damage
the air bags and you could be injured because the air
bags may no longer be functional. The protective
covers for the air bag cushions are designed to open
only when the air bags are inflating.

SAFETY 251

WARNING!(Continued)
•Relying on the air bags alone could lead to more
severe injuries in a collision. The air bags work with
your seat belt to restrain you properly. In some
collisions, air bags won’t deploy at all. Always wear
your seat belts even though you have air bags.
Front Air Bag Operation
Front Air Bags are designed to provide additional protec-
tion by supplementing the seat belts. Front air bags are not
expected to reduce the risk of injury in rear, side, or
rollover collisions. The front air bags will not deploy in all
frontal collisions, including some that may produce sub-
stantial vehicle damage — for example, some pole colli-
sions, truck underrides, and angle offset collisions.
On the other hand, depending on the type and location of
impact, 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.
When the ORC detects a collision requiring the front air
bags, it signals the inflator units. A large quantity of
non-toxic gas is generated to inflate the front air bags.
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 front air bags fully
inflate in less time than it takes to blink your eyes. The front
air bags then quickly deflate while helping to restrain the
driver and front passenger.
Knee Impact Bolsters
The Knee Impact Bolsters help protect the knees of the driver
and front passenger, and position the front occupants for
improved interaction with the front air bags.
WARNING!
•Do not drill, cut, or tamper with the knee impact
bolsters in any way.
•Do not mount any accessories to the knee impact
bolsters such as alarm lights, stereos, citizen band
radios, etc.
