28. Sway Bar Indicator Light — If EquippedThis indicator will illuminate when the front
sway bar is disconnected.
29. Electronic Stability Control (ESC) OFF Indicator
Light — If Equipped This light indicates the Electronic Stability Con-
trol (ESC) is off.
30. Electronic Throttle Control (ETC) Light This light informs you of a problem with the
Electronic Throttle Control (ETC) system. If a
problem is detected while the engine is run-
ning, the light will either stay on or flash
depending on the nature of the problem. Cycle the
ignition key when the vehicle is safely and completely
stopped and the shift lever is placed in the PARK position. The light should turn off. If the light remains on
with the engine running, your vehicle will usually be
drivable; however, see an authorized dealer for service as
soon as possible.
If the light continues to flash when the engine is running,
immediate service is required 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 to ON/RUN
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.

PanelAir is directed through the outlets in the instrument
panel. These outlets can be adjusted to direct airflow.
NOTE: The center instrument panel outlets can be
aimed so that they are directed toward the rear seat
passengers for maximum airflow to the rear.
Bi-Level Air is directed through the panel and floor outlets.
NOTE: For all settings, except full cold or full hot, there
is a difference in temperature between the upper and
lower outlets. The warmer air flows to the floor outlets.
This feature gives improved comfort during sunny but
cool conditions. Floor
Air is directed through the floor outlets with a
small amount flowing through the defrost and side
window demist outlets.
Mix Air is directed through the floor, defrost, and side
window demist outlets. This setting works best in
cold or snowy conditions that require extra heat to
the windshield. This setting is good for maintaining
comfort while reducing moisture on the windshield.
Defrost Air is directed through the windshield and side
window demist outlets. Use this mode with maxi-
mum blower and temperature settings for best wind-
shield and side window defrosting.
NOTE: The air conditioning compressor operates in
Mix, Defrost, or a blend of these modes, even if the Air

Window Fogging
Interior fogging on the windshield can be quickly re-
moved by turning the mode selector to Defrost. The
Defrost/Floor mode can be used to maintain a clear
windshield and provide sufficient heating. If side win-
dow fogging becomes a problem, increase blower speed.
Vehicle windows tend to fog on the inside in mild but
rainy or humid weather.
NOTE:Recirculate without A/C should not be used for
long periods as fogging may occur.
Side Window Demisters
A side window demister outlet is located at each end of
the instrument panel. These non-adjustable outlets direct
air toward the side windows when the system is in the
Floor, Mix, or Defrost mode. The air is directed at the area
of the windows through which you view the outside
mirrors.
Outside Air Intake
Make sure the air intake, located directly in front of the
windshield, is free of obstructions such as leaves. Leaves
collected in the air intake may reduce airflow, and if they
enter the plenum, they could plug the water drains. In
winter months, make sure the air intake is clear of ice,
slush, and snow.
A/C Air Filter — If Equipped
The A/C Filter prevents most dust and pollen from
entering the cabin. The filter acts on air coming from
outside the vehicle and recirculated air within the pas-
senger compartment. Refer to “Maintenance Procedures”
in “Maintaining Your Vehicle” for A/C Air Filter service
information or see your authorized dealer for service.
Refer to “Maintenance Schedules” for filter service
intervals.

STARTING AND OPERATING 369

Turn the ignition switch to the START position and
release when the engine starts. If the engine fails to start
within 10 seconds, turn the ignition switch to the LOCK
position, wait 10 to 15 seconds, then repeat the “Normal
Starting” procedure.
Tip Start Feature – Automatic Transmission Only
Turn the ignition switch to the START position and
release it as soon as the starter engages. The starter motor
will continue to run, but will automatically disengage
itself when the engine is running. If the engine fails to
start, the starter will disengage automatically in 10 sec-
onds. If this occurs, turn the ignition switch to the LOCK
position, wait 10 to 15 seconds, then repeat the “Normal
Starting” procedure.
Extreme Cold Weather (Below –20°F Or –29°C)
To ensure reliable starting at these temperatures, use of
an externally-powered electric engine block heater (avail-
able from your authorized dealer) is recommended.
If Engine Fails To Start
WARNING!
•Never pour fuel or other flammable liquids into
the throttle body air inlet opening in an attempt to
start the vehicle. This could result in a flash fire
causing serious personal injury.
•Do not attempt to push or tow your vehicle to get it
started. Vehicles equipped with an automatic trans-
mission cannot be started this way. Unburned fuel
could enter the catalytic converter and, once the
engine has started, ignite and damage the converter
and vehicle. If the vehicle has a discharged battery,
booster cables may be used to obtain a start from a
booster battery or the battery in another vehicle.
This type of start can be dangerous if done improp-
erly. Refer to “Jump Starting” in “What To Do In
Emergencies” for further information.

STARTING AND OPERATING 371

NEUTRAL
This range is used when vehicle is standing for pro-
longed periods with engine running. Engine may be
started in this range. Set the parking brake and shift the
transmission into PARK if you must leave the vehicle.
NOTE:Towing, coasting, or driving the vehicle for any
other reason with the shift lever in NEUTRAL can result
in severe transmission damage. Refer to “Recreational
Towing” in “Starting and Operating” and “Towing a
Disabled Vehicle” in “What To Do In Emergencies” for
further information.
OVERDRIVE
This range is used for most city and highway driving.
The transmission contains an electronically-controlled
fourth gear Overdrive, and will automatically shift from
DRIVE to OVERDRIVE if the following conditions are
present:
•The shift lever is in DRIVE.
•The O/D OFF switch has not been activated.
•Vehicle speed is above approximately 30 mph
(48 km/h).
When frequent transmission shifting occurs while using
Overdrive, such as when operating the vehicle under
heavy load conditions (for example, in hilly terrain,
strong head winds, or trailer towing), turning off over-
drive will improve performance and extend transmission
life by reducing excessive shifting and heat buildup.
