Electronic Throttle Control system. If a problem
is detected the light will come on while the
engine is running. Cycle the ignition key when
the vehicle has completely stopped and the gear selector
is placed in the P (Park) position. The light should turn
off. If the light remains lit with the engine running your
vehicle will usually be drivable, however, see your dealer
for service as soon as possible. If the light is flashing
when the engine is running, immediate service is re-
quired and you may experience reduced performance, an
elevated/rough idle or engine stall and your vehicle may
require towing. The light will come on when the ignition
is first turned on and remain on briefly as a bulb check.
If the light does not come on during starting, have the
system checked by an authorized dealer.23. Front Fog Light Indicator Light— If Equipped
This light shows the front fog lights are ON.

nuts until each nut has been tightened twice. Correct
wheel nut tightness is 130 N·m (95 ft. lbs). If in doubt
about the correct tightness, have them checked with a
torque wrench by your authorized dealer or at a service
station.
10. Lower the jack to it’s fully closed position.
WARNING!
A loose tire or jack, thrown forward in a collision or
hard stop could endanger the occupants of the ve-
hicle. Always stow the jack parts and the spare tire in
the places provided.
11. Secure the tire, jack, and tools in their proper loca-
tions.
NOTE:Tire should be stowed with the “beauty” side
up. Storing the tire upside down may result in scratchingor damage to the wheel face. Continue winching up the
tire until you hear the winch “ratchet” three times.
Double check to ensure the tire is snug against the
underbody of the vehicle. Damage to the winch cable
may result if the vehicle is driven with the tire loose.
12. Reinstall the rubber plug into the floor of the cargo
area.
JUMP STARTING PROCEDURE
NOTE:Check the test indicator on top of battery for
battery fluid level. If the indicator is clear, the level is low.
Add water to the proper level and reinstall the vent caps
before attempting to jump start the vehicle.
1. Wear eye protection and remove any metal jewelry
such as watch bands or bracelets that might make an
unintended electrical contact.
2. When boost is provided by a battery in another
vehicle, park that vehicle within booster cable reach but
WHAT TO DO IN EMERGENCIES 303

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
transmission control systems. When these systems are
operating properly, your vehicle will provide excellent
performance and fuel economy, as well as engine emis-
sions well within current government regulations.
If any of these systems require service, the OBD II system
will turn on the “Malfunction Indicator Light.” It will
also store diagnostic codes and other information to
assist your service technician in making repairs. Al-
though your vehicle will usually be drivable and not
need towing, see your dealer for service as soon as
possible.CAUTION!
•Prolonged driving with the “Malfunction Indica-
tor Light” on could cause further damage to the
emission control system. It could also affect fuel
economy and driveability. The vehicle must be
serviced before any emissions tests can be per-
formed.
•If the “Malfunction Indicator Light” is flashing
while the engine is running, severe catalytic con-
verter damage and power loss will soon occur.
Immediate service is required.
Loose Fuel Filler Cap Message
After fuel is added, the vehicle diagnostic system can
determine if the fuel filler cap is loose, improperly
installed, or damaged. A loose fuel filler cap message will
be displayed in the instrument cluster. Tighten the gas

cap until aclickingsound is heard. This is an indication
that the 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 problem is detected twice in a row, the system will
turn on the Malfunction Indicator Light (MIL). Resolving
the problem will turn the MIL light 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 which have an I/M (Inspection and
Maintenance) requirement, this check verifies the
following: the MIL (Malfunction Indicator Lamp)is functioning and is not on when the engine is running,
and that the OBD (On Board Diagnostic) system is ready
for testing.
Normally, the OBD system will be ready. The OBD
system maynotbe ready if your vehicle was recently
serviced, if you recently had a dead battery, or a battery
replacement. If the OBD 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 system is ready, you must do
the following:
1. Insert your ignition key into the ignition switch.
2. Turn the ignition to the ON position, but do not crank
or start the engine.
3. If you crank or start the engine, you will have to start
this test over.
