the ON position before engine start. If the bulb does not
come on when turning the key from OFF to ON, have the
condition checked promptly.
Certain conditions such as a loose or missing gas cap,
poor fuel quality, etc., may illuminate the MIL after
engine start. The vehicle should be serviced if the light
stays on through several of your typical driving cycles. In
most situations, the vehicle will drive normally and will
not require towing.
The MIL flashes to alert to serious conditions that could
lead to immediate loss of power or severe catalytic
converter damage. The vehicle should be serviced at an
authorized dealer as soon as possible if this occurs.
16. Engine Temperature Warning LightThis light warns of an overheated engine condi-
tion. As temperatures rise and the gauge ap-
proaches H,this indicator will illuminate and a
single chime will sound after reaching a set threshold. Further overheating will cause the temperature gauge to
pass
H,the indicator will continuously flash and a
continuous chime will occur until the engine is allowed
to cool.
If the light turns on while driving, safely pull over and
stop the vehicle. If the A/C system is on, turn it off. Also,
shift the transmission into NEUTRAL and idle the ve-
hicle. If the temperature reading does not return to
normal, turn the engine off immediately and call for
service. Refer to “If Your Engine Overheats” in Section 6
for more information.
17. Electronic Throttle Control (ETC) Light This light informs you of a problem with the
Electronic Throttle Control (ETC) system. 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. UNDERSTANDING YOUR INSTRUMENT PANEL 247

NOTE: This vehicle is equipped with a transaxle shift
interlocking system. The brake pedal must be pressed
to shift out of PARK.
Extreme Cold Weather (Below20°F or –29°C)
Follow the same instructions in the “Normal Starting”
procedure.
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 The 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.
(Continued) WARNING! (Continued)

Do not attempt to push or tow your vehicle to get
it started. Vehicles equipped with an automatic
transaxle 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 improperly. Refer
to “Jump Starting” in Section 6 of this manual.
If the engine fails to start after you have followed the
“Normal Starting” procedure, it may be flooded. Push
the accelerator pedal all the way to the floor and hold it
there while cranking the engine. This should clear any
excess fuel in case the engine is flooded.
330 STARTING AND OPERATING

An out-of-tune engine, or certain fuel or ignition
malfunctions, can cause the catalytic converter to
overheat. If you notice a pungent burning odor or
some light smoke, your engine may be out of tune or
malfunctioning and may require immediate service.
Contact your authorized dealer for service assistance.
The use of fuel additives which are now being sold as
octane enhancers is not recommended. Most of these
products contain high concentrations of methanol.
Fuel system damage or vehicle performance problems
resulting from the use of such fuels or additives is not
the responsibility of the manufacturer.
NOTE: Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.
Carbon Monoxide Warnings WARNING!
Carbon monoxide (CO) in exhaust gases is deadly.
To prevent carbon monoxide poisoning DO NOT
inhale exhaust gases. They contain carbon monox-
ide, a colorless and odorless gas which can kill.
NEVER run the engine in a closed area, such as a
garage, and NEVER sit in a parked vehicle with
the engine running for an extended period. If the
vehicle is stopped in an open area with the engine
running for more than a short period, adjust the
ventilation system to force fresh, outside air into
the vehicle.

382 STARTING AND OPERATING

CAUTION!For vehicles equipped with Stow ’n Got
seating, the
winch mechanism is designed specifically to stow a
compact spare tire only. Do not attempt to use the
winch to stow the full size flat tire, or any other
full-size tire. Vehicle damage may result.
JUMP-STARTING PROCEDURE WARNING!

Do not attempt to push or tow the vehicle to get it
started. Vehicles equipped with an automatic
transmission 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.
(Continued) WARNING! (Continued)

If the vehicle has a discharged battery, booster
cables may be used to obtain a start from another
vehicle. This type of start can be dangerous if done
improperly, so follow this procedure carefully.
Battery fluid is a corrosive acid solution; do not
allow battery fluid to contact eyes, skin or cloth-
ing. Do not lean over a battery when attaching
clamps, or allow the clamps to touch each other. If
acid splashes in eyes or on skin, flush the contami-
nated area immediately with large quantities of
water.
A battery generates hydrogen gas, which is flam-
mable and explosive. Keep all flames and sparks
away from the vent holes. Do not use a booster
battery or any other booster source with an output
that exceeds 12-Volts.

used to assure most efficient service. MOPARtengine air
cleaner filters are a high quality filter and are
recommended.
Exhaust System
The best protection against carbon monoxide entry into
the vehicle body is a properly maintained engine exhaust
system.
Whenever a change is noticed in the sound of the exhaust
system, when exhaust fumes can be detected inside the
vehicle, or when the underside or rear of the vehicle is
damaged, have a competent mechanic inspect the com-
plete exhaust system and adjacent body areas for broken,
damaged, deteriorated, or mispositioned parts. Open
seams or loose connections could permit exhaust fumes
to seep into the passenger compartment. In addition,
inspect the exhaust system each time the vehicle is raised
for lubrication or oil change. Replace as required. WARNING!
Exhaust gases can injure or kill. They contain carbon
monoxide (CO) which is colorless and odorless.
Breathing it can make you unconscious and can
eventually poison you. To avoid breathing CO, refer
to “Exhaust Gas” in the Safety Tips section of this
manual.
The catalytic converter requires the use of unleaded fuel
only. Leaded gasoline will destroy the effectiveness of the
catalyst as an emission control device.
Under normal operating conditions, the catalytic con-
verter will not require maintenance. However, it is im-
portant to keep the engine properly tuned to assure
proper catalyst operation and prevent possible catalyst
damage.
MAINTAINING YOUR VEHICLE 443 7

CAUTION!Damage to the catalytic converter can result if your
vehicle is not kept in proper operating condition. In
the event of engine malfunction, particularly involv-
ing engine misfire or other apparent loss of perfor-
mance, have your vehicle serviced promptly. Contin-
ued operation of your vehicle with a severe
malfunction could cause the converter to overheat,
resulting in possible damage to the converter and the
vehicle.
NOTE: Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you. WARNING!A hot exhaust system can start a fire if you park over
materials that can burn. Such materials might be
grass or leaves coming into contact with your exhaust
system. Do not park or operate your vehicle in areas
where your exhaust system can contact anything that
can burn.
In unusual situations involving grossly malfunctioning
engine operation, a scorching odor may indicate severe
and abnormal catalyst overheating. If this occurs, the
vehicle should be stopped, the engine shut OFF and the
vehicle allowed to cool. Thereafter, service, including a
tune-up to manufacturer’s specifications, should be ob-
tained immediately.
