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 will remain on solid when a
system fault is detected. The system fault will also sound a
chime. If the ignition key is cycled, this sequence will
repeat, providing the system fault still exists. A system
fault can occur by any of the following scenarios:
Base Tire Pressure Monitoring
Vehicles not equipped with EVIC 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 = L eft F ront
rF = r ight F ront
Lr = L eft r ear
rr = r ight r ear
Premium Tire Pressure Monitoring
Vehicles equipped with a EVIC will display specific tire
pressure information. When tire pressure is low the low
tire ISO telltale will illuminate and the EVIC will display
actual individual tire pressure when the tire pressure is
lower than the Placard Value.
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.
5 STARTING AND OPERATING 499

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, 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
and the “Tire Pressure Monitoring Telltale Light” will
turn ON. After driving the vehicle for up to 20 minutes
above 15 mph (24 km/h), the “Tire Pressure Monitor-
ing 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 Tell-
tale Light” will turn OFF, as long as no tire pressure is500 STARTING AND OPERATING

Proper towing or lifting equipment is required to prevent
damage to your vehicle. Use only tow bars and other
equipment designed for this purpose, following equip-
ment manufacturer ’s instructions. Use of safety chains is
mandatory. Attach a tow bar or other towing device to
main structural members of the vehicle, not to bumpers
or associated brackets. State and local laws regarding
vehicles under tow must be observed.
If you must use the accessories (wipers, defrosters, etc.)
while being towed, the ignition must be in the ON/RUN
position, not the ACC position.
If the vehicle’s battery is discharged, refer to “Shift Lever
Override” in “What To Do In Emergencies” for instruc-
tions on shifting the automatic transmission out of PARK
for towing. CAUTION!Do not use sling type equipment when towing. When
securing the vehicle to a flatbed truck, do not attach to
front or rear suspension components. Damage to your
vehicle may result from improper towing.
Without The Ignition Key
Special care must be taken when the vehicle is towed
with the ignition in the OFF position. The only approved
method of towing without the key fob is with a flatbed
truck. Proper towing equipment is necessary to prevent
damage to the vehicle.
6 WHAT TO DO IN EMERGENCIES 557

gas cap is properly tightened. Press the odometer reset
button to turn the message off. If the problem persists,
the message will appear the next time the vehicle is
started. This might indicate a damaged cap. If the prob-
lem is detected twice in a row, the system will turn on the
MIL. Resolving the problem will turn the MIL off.
EMISSIONS INSPECTION AND MAINTENANCE
PROGRAMS
In some localities, it may be a legal requirement to pass
an inspection of your vehicle’s emissions control system.
Failure to pass could prevent vehicle registration.
For states that require an Inspection and Mainte-
nance (I/M), this check verifies the “Malfunction
Indicator Light (MIL)” is functioning and is not
on when the engine is running, and that the OBD II
system is ready for testing. Normally, the OBD II system will be ready. The OBD II
system may not be ready if your vehicle was recently
serviced, recently had a dead battery or a battery replace-
ment. If the OBD II system should be determined not
ready for the I/M test, your vehicle may fail the test.
Your vehicle has a simple ignition key-actuated test,
which you can use prior to going to the test station. To
check if your vehicle’s OBD II system is ready, you must
do the following:
1. Turn the ignition switch to the ON position, but do not
crank or start the engine.
2. If you crank or start the engine, you will have to start
this test over.
3. As soon as you turn the ignition switch to the ON
position, you will see the MIL symbol come on as part
of a normal bulb check.

Front Park/Turn Signal
1. Remove the front grille. Turn the retainers along the
top 1/4 turn counterclockwise and remove.
2. Pull the bottom of the grille away starting at one side
and working toward the other.
3. Turn the socket assembly 1/4 turn counterclockwise
and remove from housing. Pull the bulb straight from
the socket to replace.
Front Side Marker
1. Reach under the front fender flare and locate the front
side marker socket.
2. Turn the socket assembly counterclockwise 1/3 turn
and remove it from the housing. Pull the bulb straight
from the socket to replace. Front Fog Lamp
1. Reach under the vehicle to access the back of the front
fog lamp.
2. Disconnect the wire harness connector from the front
fog lamp connector receptacle.
3. Firmly grasp the bulb by the two latch features and
squeeze them together to unlock the bulb from the
back of the front fog lamp housing.
4. Pull the bulb straight out from the keyed opening in
the housing and then connect the replacement bulb.
CAUTION!Do not touch the new bulb with your fingers. Oil
contamination will severely shorten bulb life. If the
bulb comes in contact with any oily surface, clean the
bulb with rubbing alcohol.608 MAINTAINING YOUR VEHICLE
