HAZARD WARNING FLASHER
The flasher switch is located on the instrument
panel, below the radio. Depress the switch and
both cluster indicators and all front and rear direc-
tional signals will flash. Depress the switch again to turn
Hazard Warning Flashers off.
Do not use this emergency warning system when the
vehicle is in motion. Use it when your vehicle is disabled
and it is creating a safety hazard for other motorists.
If it is necessary to leave the vehicle to go for service, the
flasher system will continue to operate with the ignition
key removed and the vehicle locked.
NOTE: With extended use, the flasher may wear down
your battery. IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the
potential for overheating by taking the appropriate ac-
tion.
² On the highways Ð Slow down.
² In city traffic Ð While stopped, put transaxle in
NEUTRAL, but do not increase engine idle speed.
If the pointer rises to the H (red) mark, the instrument
cluster will sound a chime. Pull over and stop the vehicle
with the engine at idle, when safe. Turn off the air
conditioning and wait until the pointer drops back into
the normal range. If the pointer remains on the H (red)
mark for more than a minute, turn the engine off imme-
diately and call for service.348 WHAT TO DO IN EMERGENCIES

NOTE: There are steps that you can take to slow down
an impending overheat condition. If your air conditioner
is on, turn it off. The air conditioning system adds heat to
the engine cooling system and turning off the A/C
removes this heat. You can also turn the Temperature
control to maximum heat, the Mode control to floor, and
the fan control to High. This allows the heater core to act
as a supplement to the radiator and aids in removing heat
from the engine cooling system. CAUTION!Driving with a hot cooling system could damage
your vehicle. If temperature gauge reads ªHº, pull
over and stop the vehicle with the engine at idle,
when safe. Turn the air conditioner off and wait until
the pointer drops back into the normal range. After
appropriate action has been taken, if the pointer
remains on the ªHº, turn the engine off immediately,
and call for service. WHAT TO DO IN EMERGENCIES 349

WARNING!A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call a service center if your
vehicle overheats. If you decide to look under the
hood yourself, refer to Section 7, Maintenance, of this
manual. Follow the warnings under the Cooling
System Pressure Cap paragraph.
ENGINE OIL OVERHEATING (2.4L ENGINE ONLY)
Ð IF EQUIPPED
During sustained high-speed driving or trailer tow up
long grades on a hot day, the engine oil temperature may
become too hot. If this happens, the ªHOTOILº message
flashes in the odometer and the vehicle speed will be
reduced to 53 mph (85 km/h) until the engine oil
temperature is reduced. NOTE: The vehicle speed is reduced to a maximum of
53 mph (85 km/h). You may of course, reduce your
vehicle speed further if needed.
JACKING AND TIRE CHANGING
WARNING!² Getting under a jacked-up vehicle is dangerous.
The vehicle could slip off the jack and fall on you.
You could be crushed. Never get any part of your
body under a vehicle that is on a jack. If you need
to get under a raised vehicle, take it to a service
center where it can be raised on a lift.
² The jack is designed to use as a tool for changing
tires only. The jack should not be used to lift the
vehicle for service purposes. The vehicle should
be jacked on a firm level surface only. Avoid ice or
slippery areas.350 WHAT TO DO IN EMERGENCIES

covers with care to avoid contact with any sharp
edges.
7. Lower the vehicle by turning the jack screw to the left.
8. Finish tightening the nuts. Push down on the wrench
while tightening the wheel nuts. Alternate nuts, until
each nut has been tightened twice. Correct wheel nut
torque is 100 ft. lbs (135 N´m). If you doubt that you have
tightened the nuts correctly, have them checked with a
torque wrench by your dealer or at a service station.
9. Remove the wheel blocks and lower the jack until it is
free. Reassemble the lug wrench to the jack assembly and
stow it in the spare tire area. Secure the assembly using
the means provided. 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.
10. Place the deflated (flat) tire in the cargo area and have
the tire repaired or replaced as soon as possible.
WARNING!A loose tire thrown forward in a collision or hard
stop could injure the occupants in the vehicle. Have
the deflated (flat) tire repaired or replaced
immediately. WHAT TO DO IN EMERGENCIES 357

5. Connect the other cable, first to the negative terminal
of the booster battery and then to the engine ground (-)
of the vehicle with the discharged battery. Make sure
you have a good contact on the engine ground. Refer to
the following illustration for jump-starting connections.
6. If the vehicle is equipped with Sentry Key t Immobi-
lizer, turn the ignition switch to the ON position for three
seconds before moving the ignition switch to the START
position.
7. Start the engine in the vehicle that has the booster
battery, let the engine idle a few minutes, and then start
the engine in the vehicle with the discharged battery.
8. When removing the jumper cables, reverse the se-
quence exactly. Be careful of the moving belts and fan.
9. Reinstall the protective cover over the remote jump-
start positive battery post. NOTE: Refer to ªMaintenance Proceduresº in Section 7
of this manual for information on accessing the battery
for service or replacement.
WARNING!Any procedure other than above could result in:
1. Personal injury caused by electrolyte squirting out
the battery vent;
2. Personal injury or property damage due to battery
explosion;
3. Damage to charging system of booster vehicle or

ONBOARD DIAGNOSTIC SYSTEM Ð 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
transaxle control systems. When these systems are oper-
ating properly, your vehicle will provide excellent per-
formance and fuel economy, as well as maintaining
engine emissions well within current government regu-
lations.
If any of these systems require service, the OBD II
system will turn on the Malfunction Indicator
Light (MIL). It will also store diagnostic codes
and other information to assist an authorized service
technician in making repairs. Although your vehicle will
usually be drivable and not need towing, see your
authorized dealer for service as soon as possible. CAUTION!² Prolonged driving with the MIL on could cause
further damage to the emission control system. It
could also affect fuel economy and drivability. The
vehicle must be serviced before any emissions
tests can be performed.
² If the MIL is flashing while the engine is running,
severe catalytic converter 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 possibly loose or
improperly installed. A ªgASCAPº message will be dis-
played in the instrument cluster. Tighten the gas cap until
a 9 clicking 9 sound is heard. This is an indication that the
gas cap is properly tightened. Press the Trip Odometer MAINTAINING YOUR VEHICLE 371
7

RESET button to turn off the message. 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 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 this 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 the 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, the vehicle may fail the test.
This vehicle has a simple ignition key-actuated test,
which you can use prior to going to the test station. To
check if this vehicle's OBD II system is ready, you must
do the following:
1. Insert the 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.
4. As soon as you turn the ignition key to the ON
position, you will see the MIL symbol come on as part of
a normal bulb check.372 MAINTAINING YOUR VEHICLE

5. Approximately 15 seconds later, one of two things will
happen:
a. The MIL will flash for about 10 seconds and then
return to being fully illuminated until you turn OFF
the ignition key or start the engine. This means that the
vehicle's OBD II system is not ready and you should
not proceed to the I/M station.
b. The MIL will not flash at all and will remain fully
illuminated until you turn OFF the ignition key or start
the engine. This means that the vehicle's OBD II
system is ready, and you can proceed to the I/M
station.
If the OBD II system is not ready, you should see an
authorized dealer or repair facility. If this vehicle was
recently serviced or had a battery failure or replacement,
you may need to do nothing more than drive the vehicle as you normally would in order for the OBD II system to
update. A recheck with the above test routine may then
indicate that the system is now ready.
Regardless of whether the vehicle's OBD II system is
ready or not ready, if the MIL is illuminated during
normal vehicle operation, you should have the vehicle
serviced before going to the I/M station. The I/M station
can fail the vehicle because the MIL is on with the engine
running.
REPLACEMENT PARTS
Use of genuine Mopar t parts for normal/scheduled
maintenance and repairs is highly recommended to en-
sure the designed performance. Damage or failures
caused by the use of non-Mopar t parts for maintenance
and repairs will not be covered by the manufacturer's
warranty. MAINTAINING YOUR VEHICLE 373
