Safety Checks You Should Make Inside the
Vehicle
Seat Belts
Inspect the seat belt system periodically, checking for
cuts, frays and loose parts. Damaged parts must be
replaced immediately. Do not disassemble or modify the
system.
Seat belt assemblies must be replaced after an accident if
they have been damaged i.e., (bent retractor, torn web-
bing, etc.). If there is any question regarding belt or
retractor condition, replace the belt.
Airbag Warning Light
The light should come on, and remain on for six to eight
seconds as a bulb check, when the ignition switch is first
turned ON. If the bulb is not lit during starting, have it
replaced. If the light stays on or comes on while driving,
have the system checked by an authorized dealer.
Defrosters
Check operation by selecting the DEFROST mode and
place the blower control on high speed. You should be
able to feel the air directed against the windshield. See
your authorized dealer for service if your defroster is
inoperable.
Safety Checks You Should Make Outside the
Vehicle
Tires
Examine tires for excessive tread wear or uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread. Inspect for tread cuts or sidewall
cracks. Check wheel nuts for tightness. Check the tires
(including spare) for proper pressure.

WARNING!
Temporary use spare tires are for emergency use only.
With these tires, do not drive more than 50 mph
(80 km/h). Temporary use spare tires have limited
tread life. When the tread is worn to the tread wear
indicators, the temporary use spare tire needs to be
replaced. Be sure to follow the warnings, which
apply to your spare. Failure to do so could result in
spare tire failure and loss of vehicle control.
Do not install a wheel cover or attempt to mount a
conventional tire on the compact spare wheel, since the
wheel is designed specifically for the compact spare.
Do not install more than one compact spare tire/wheel
on the vehicle at any given time.
CAUTION!
Because of the reduced ground clearance, do not take
your vehicle through an automatic car wash with the
compact spare installed. Damage to the vehicle may
result.
Limited-Use Spare — If Equipped
The limited-use spare tire is for temporary emergency
use on your vehicle. This tire is identified by a limited-
use spare tire warning label located on the limited-use
spare tire and wheel assembly. This tire may look like the
original equipped tire on the front or rear axle of your
vehicle, but it is not. Installation of this limited-use spare
tire affects vehicle handling. Since it is not the same tire,
replace (or repair) the original tire and reinstall on the
vehicle at the first opportunity.

WARNING!
The limited-use spare tires are for emergency use
only. Installation of this limited-use spare tire affects
vehicle handling. With this tire, do not drive more
than 50 mph (80 km/h). Keep inflated to the cold tire
inflation pressure listed on either your tire placard or
limited-use spare tire and wheel assembly. Replace
(or repair) the original tire at the first opportunity
and reinstall it on your vehicle. Failure to do so could
result in loss of vehicle control.
Tire Spinning
When stuck in mud, sand, snow, or ice conditions, do not
spin your vehicle’s wheels above 35 mph (55 km/h).
WARNING!
Fast spinning tires can be dangerous. Forces gener-
ated by excessive wheel speeds may cause tire dam-
age or failure. A tire could explode and injure some-
one. Do not spin your vehicle’s wheels faster than
35 mph (55 km/h) when you are stuck, and do not let
anyone near a spinning wheel no matter what the
speed.

Base System
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.
The TPMS consists of the following components:
•Receiver Module
•Four Tire Pressure Monitoring Sensors
•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-sizespare tire can be used in place of any of the four road
tires. A low spare tire will not cause the Tire Pressure
Monitoring Telltale Light to illuminate, a warning mes-
sage to appear, or the chime to sound.
The Tire Pressure Monitoring Telltale Light will
illuminate in the instrument cluster, a “TIRE LOW
PRESSURE” message will display in the instru-
ment cluster for 60 seconds, and an audible chime will be
activated, when one or more of the four active road tire
pressures are low. Should this occur, you should stop as
soon as possible, check the inflation pressure of each tire
on your vehicle, and inflate each tire to the vehicle’s
recommended cold placard pressure value. The system
will automatically update and the Tire Pressure Monitor-
ing Telltale Light will extinguish, once the updated tire
pressures have been received. The vehicle may need to be
driven for up to 20 minutes above 15 mph (24 km/h) to
receive this information.

The Tire Pressure Monitoring Telltale Light will flash on
and off for 75 seconds, and remain on solid when a
system fault is detected. In addition, a “CHECK TPM
SYSTEM” message will be displayed for 75 seconds when
a system fault is detected, and a chime will sound. If the
ignition key is cycled, this sequence will repeat, provid-
ing the system fault still exists. The Tire Pressure Moni-
toring Telltale Light will turn off when the fault condition
no longer exists. A system fault can occur by any of the
following:
1. Jamming due to electronic devices or driving next to
facilities emitting the same Radio Frequencies as the TPM
sensors.
2. Installing some form of aftermarket window 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.
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). 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, a “TIRE LOW PRESSURE” message will be
displayed in the instrument cluster for 60 seconds, and
a chime to sound. 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 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 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 key cycle, a chime will sound, a
“TIRE LOW PRESSURE” message will be displayed in
the instrument cluster for 60 seconds, and the Tire
Pressure Monitoring Telltale Light will turn ON. After
driving the vehicle for up to 20 minutes above 15 mph
(25 km/h), the Tire Pressure Monitoring Telltale Light
will flash on and off for 75 seconds and then remain on
solid. In addition, a “CHECK TPM SYSTEM” message
will be displayed for 75 seconds. For each subsequent
ignition key cycle, a chime will sound, a “CHECK
TPM SYSTEM” message will be displayed for 75 sec-
onds, and the Tire Pressure Monitoring Telltale Light
will flash on and off for 75 seconds and then remain onsolid. 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.

The Tire Pressure Monitor System (TPMS) consists of the
following components:
•Receiver Module
•Four Tire Pressure Monitoring Sensors
•Three Trigger Modules (mounted in three of the four
wheel wells)
•Various Tire Pressure Monitoring System Messages,
which display in the Electronic Vehicle Information
Center (EVIC), 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 roadtires. A low spare tire will set the “SPARE LOW PRES-
SURE” message, but it will not cause the Tire Pressure
Monitoring Telltale Light to illuminate or the chime to
sound.
Tire Pressure Monitoring Low Pressure Warnings
The Tire Pressure Monitoring Telltale Light will
illuminate in the instrument cluster, and an au-
dible chime will be activated, when one or more of
the four active road tire pressures are low. In addition, the
EVIC will display one or more Low Pressure messages
(Left Front, Left Rear, Right Front, Right Rear) for three
seconds, and a graphic display of the pressure value(s)
with the low tire(s) “flashing.” Refer to “Electronic Ve-
hicle Information Center (EVIC)” in Section 4 of this
manual.

case, theCHECK TPM SYSTEMmessage is then fol-
lowed by a graphic display, with pressure values still
shown. This indicates the pressure values are still being
received from the TPM Sensors. However, the system still
needs to be serviced as long as theCHECK TPM
SYSTEMmessage exists.
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). 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, a chime to sound, a Low Pressure message to
appear in the EVIC, and the graphic display will still
show the low tire pressure value “flashing.” Driving
the vehicle for up to 20 minutes above 15 mph
(24 km/h) will turn OFF the Tire Pressure MonitoringTelltale Light as long as none of road tires are below
the low pressure warning threshold. The EVIC will
also display a “SPARE LOW PRESSURE” message,
and the graphic display will show a tire pressure value
in place of the “flashing” low tire pressure value.
•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 key cycle, the Tire Pressure
Monitoring Telltale Light will remain ON, a chime will
sound, and the EVIC will still display a “flashing”
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

Spare Tire Removal
Fit the jack handle extension over the drive nut. Use the
Lug Wrench to rotate the nut counterclockwise until the
spare is on the ground with enough slack in the cable to
allow to pull the tire out from under the vehicle.
CAUTION!
The winch mechanism is designed for use with the
jack extension tube only. Use of an air wrench or
other power tools is not recommended and can dam-
age the winch.
When the spare is clear, tilt the retainer at the end of the
cable and pull it through the center of the wheel.
