NOTE:Refer toSynchronizing ESPunderElectronic
Stability Programin Section 5 if the ESP/BAS light (in
the instrument cluster) remains on continuously after
starting the engine of the vehicle with the discharged
battery.
8. When removing the jumper cables, reverse the above
sequence exactly. Be careful of the moving belts and fan.
WARNING!
Any procedure other than above could result in:
•Personal injury caused by electrolyte squirting out
the battery vent
•Personal injury or property damage due to battery
explosion
•Damage to charging system of booster vehicle or
of immobilized vehicle
FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand, or snow, it
can often be moved by a rocking motion. Turn your
steering wheel right and left to clear the area around the
front wheels. Then shift back and forth between RE-
VERSE and DRIVE. Usually, the least accelerator pedal
pressure to maintain the rocking motion without spin-
ning the wheels is most effective.
NOTE:Turn off the Electronic Stability Program (ESP)
before rocking the vehicle. Refer to “Electronic Stability
Program,” or “Traction Control” in Section 5.

CAUTION!
•When “rocking” a stuck vehicle by moving be-
tween “1st” and REVERSE, do not spin the wheels
faster than 15 mph (24 km/h), or drivetrain damage
may result.
•Racing the engine or spinning the wheels too fast
may lead to transmission overheating and failure.
It can also damage the tires. Do not spin the
wheels above 35 mph (55 km/h).
WARNING!
Fast spinning tires can be dangerous. Forces gener-
ated by excessive wheel speeds may cause tire dam-
age or failure. A tire could explode and injure some-
one. Do not spin your vehicle’s wheels faster than 35
mph (55 km/h) when you are stuck, and don’t let
anyone near a spinning wheel, no matter what the
speed.
TOWING A DISABLED VEHICLE
Without The Ignition Key
Special care must be taken when the vehicle is towed
with the ignition in the LOCK position. The only ap-
proved method of towing without the ignition key is
with a flat-bed truck. Proper towing equipment is neces-
sary to prevent damage to the vehicle.

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 (MIL). 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 authorized dealer for service as
soon as possible.CAUTION!
Prolonged driving with the “MIL” on could cause
further damage to the emissions control system. It
could also affect fuel economy and driveability. The
vehicle must be serviced before any emissions tests
can be performed.
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
If the vehicle diagnostic system determines that the fuel
filler cap is loose, improperly installed, or damaged, a
“Check Gascap” message will display in the Electronic
Vehicle Information Center (EVIC) (if equipped). If this
occurs, tighten the fuel filler cap properly and press the
MAINTAINING YOUR VEHICLE 349

Page 352 of 442

TRIP ODOMETER button to turn off the message. If the
problem continues, the message will appear the next time
the vehicle is started.
A loose, improperly installed, or damaged fuel filler cap
may also turn on the MIL.
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 I/M (Inspection and
Maintenance), this check verifies the MIL is func-
tioning and is not on when the engine is running,
and that the OBD II system is ready for testing.Normally, the OBD system will be ready. The OBD II
system maynotbe ready if your vehicle was recently
serviced or recently had a dead battery or had a battery
replacement. 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. 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.
4. As soon as you turn your key to the ON position, you
will see the MIL symbol come on as part of a normal bulb
check.

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
your vehicle’s OBD II system isnot readyand you
shouldnotproceed 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 your vehicle’s OBD II
system isready, and you can proceed to the I/M
station.
If your OBD II system isnot ready,you should see your
authorized dealer or repair facility. If your vehicle was
recently serviced or had a battery failure or replacement,
you may need to do nothing more than drive your
vehicle as you normally would in order for your OBD IIsystem to update. A recheck with the above test routine
may then indicate that the system is now ready.
Regardless of whether your vehicle’s OBD II system is
ready or not ready, if the MIL is illuminated during
normal vehicle operation, you should have your vehicle
serviced before going to the I/M station. The I/M station
can fail your vehicle because the MIL is on with the
engine running.
REPLACEMENT PARTS
Use of genuine MOPARparts for normal/scheduled
maintenance and repairs is highly recommended to en-
sure the designed performance. Damage or failures
caused by the use of non-MOPARparts for maintenance
and repairs will not be covered by the manufacturer’s
warranty.
