ONBOARD DIAGNOSTIC
SYSTEM — OBD II
Your vehicle is equipped with a sophisticated
Onboard Diagnostic system called OBD II.
This system monitors the performance of the
emissions, engine, and automatic transmis-
sion control systems. When these systems are
operating properly, your vehicle will provide
excellent performance and fuel economy, as
well as engine emissions well within current
government regulations.

2. Installing some form of aftermarket win-
dow tinting that affects radio wave
signals.
3. Lots of snow or ice around the wheels or
wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with
TPM sensors.
Vehicles not equipped with instrument clus-
ter display will inform the driver which tire(s)
are low but not provide actual tire pressure.
The low tire ISO telltale will illuminate along
with “LoTIrE” message displayed in the ODO
and then it will scroll to which tire location is
lower than the Placard Value.
Tire location will be displayed as follows:
LF =LeftFront
rF =rightFront
Lr =Leftrear
rr =rightrearNOTE:
• 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 key cycle will still show the
“Tire Pressure Monitoring Telltale Light” to
be ON, and a chime to sound. Driving the
vehicle for up to 10 minutes above 15 mph
(24 km/h) will turn OFF the “Tire Pressure
Monitoring Telltale Light” as long as none
of the road tires are below the low pressure
warning threshold.
• If your vehicle is not equipped with a
matching full-size spare wheel and tire as-
sembly, 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 key cycle, a chime will
sound and the “Tire Pressure MonitoringTelltale Light” will turn ON. After driving
the vehicle for up to 10 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. 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 10 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.

will no longer be highlighted or shown in a
different color and the Tire Pressure Monitor-
ing 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 plac-
ard pressure in order to turn the Tire Pressure
Monitoring Telltale Light off.
The vehicle may need to be driven for up to
10 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 de-
tected. 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 Pressure 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 follow-
ing:
• Jamming due to electronic devices or driv-
ing 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 housings.
• Using tire chains on the vehicle.
• Using wheels/tires not equipped with TPM
sensors.
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 swappedwith 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 clus-
ter, and the graphic display will still show
the low tire pressure value highlighted or
shown in a different color. Driving the ve-
hicle for up to 10 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 as-
sembly, 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 re-
main ON, a chime will sound, and the
instrument cluster will still display a high-
lighted or different color pressure value in

8. Do not lean against the door or window. If
your vehicle has side air bags, and deploy-
ment occurs, the side air bags will inflate
forcefully into the space between occu-
pants and the door and occupants could
be injured.
9. If the air bag system in this vehicle needs
to be modified to accommodate a dis-
abled person, refer to the “Customer As-
sistance” section for customer service
contact information.
WARNING!
• NEVER use a rearward facing child re-
straint on a seat protected by an ACTIVE
AIRBAG in front of it, DEATH or SERI-
OUS INJURY to the CHILD can occur.
• Only use a rear-facing child restraint in a
vehicle with a rear seat.
• 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.
Seat Belt Systems
Buckle up even though you are an excellent
driver, even on short trips. Someone on the
road may be a poor driver and could cause a
collision that includes you. This can happen
far away from home or on your own street.
Research has shown that seat belts save
lives, and they can reduce the seriousness of
injuries in a collision. Some of the worst
injuries happen when people are thrown from
the vehicle. Seat belts reduce the possibility
of ejection and the risk of injury caused by
striking the inside of the vehicle. Everyone in
a motor vehicle should be belted at all times.
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 posi-
tion, a chime will signal for a few seconds. If
the driver or outboard front seat passenger (if
equipped with outboard front passenger seat
BeltAlert) is unbuckled when the ignition
switch is first in the START or ON/RUN posi-
tion the Seat Belt Reminder Light will turn on
and remain on until both outboard front seat
belts are buckled. The outboard front passen-
ger seat BeltAlert is not active when an out-
board 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 out-
board front seat passenger is unbuckled (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

carpet. Fully depress each pedal to
check for interference with the accelera-
tor, brake, or clutch pedals then re-
install the floor mats.
• It is recommended to only use mild soap
and water to clean your floor mats. After
cleaning, always check your floor mat
has been properly installed and is se-
cured to your vehicle using the floor mat
fasteners by lightly pulling mat.
Periodic Safety Checks You Should Make
Outside The Vehicle
Tires
Examine tires for excessive tread wear and
uneven wear patterns. Check for stones,
nails, glass, or other objects lodged in thetread or sidewall. Inspect the tread for cuts
and cracks. Inspect sidewalls for cuts,
cracks, and bulges. Check the wheel nuts for
tightness. Check the tires (including spare)
for proper cold inflation pressure.
Lights
Have someone observe the operation of brake
lights and exterior lights while you work the
controls. Check turn signal and high beam
indicator lights on the instrument panel.
Door Latches
Check for proper closing, latching, and lock-
ing.
Fluid Leaks
Check area under vehicle after overnight
parking for fuel, coolant, oil, or other fluid
leaks. Also, if gasoline fumes are detected or
if fuel, or brake fluid leaks are suspected. The
cause should be located and corrected imme-
diately.
