Your vehicle is equipped with two 12-Volt batteries. If it
becomes necessary to use a booster battery with jumper
cables to start a vehicle’s engine because its batteries are
discharged, the following procedure should be used:
Set the parking brake and place the transmission in
PARK. Turn off lights, heater and other electrical loads.
Observe charge indicator (if equipped) in both batteries.
If the indicator (if equipped) is light or yellow on either
battery, replace that battery.CAUTION!
Use the Jump-Start Procedure only when the charge
indicator (if equipped) in both batteries is dark in the
center. Do not attempt jump-starting when either
battery charge indicator (if equipped) is bright or
yellow. If the charge indicator (if equipped) has a
green dot in the center, failure to start is not due to a
discharged battery and cranking system should be
checked.
1. Attach one jumper cable to the positive terminal of
booster battery and the other end of the same cable to the
positive terminal of the discharged battery.

WARNING!
Do not permit vehicles to touch each other as this
could establish a ground connection and personal
injury could result.2. Connect one end of the other jumper cable to negative
(-) post of booster battery. Connect the other end of the
jumper cable to a good ground on the engine block of the

vehicle with the discharged battery. Make sure a good
connection is made, free of dirt and grease.
WARNING!
•Do not connect the cable to the negative post of the
discharge battery. The resulting electrical spark
could cause the battery to explode.
•During cold weather when temperatures are be-
low freezing point, electrolyte in a discharged
battery may freeze. Do not attempt jump-starting
because the battery could rupture or explode. The
battery temperature must be brought up above
freezing point before attempting to jump-start.
3. Take care that the clamps from one cable do not
inadvertently touch clamps from the other cable. Do not
lean over the battery when making connection. The
negative connection must provide good electrical con-
ductivity and current carrying capacity. 4. After the engine is started or if the engine fails to start,
cables must be disconnected in the following order:
a. Disconnect the negative cable at the engine ground.
b. Disconnect the negative cable at the negative post
on booster battery.
c. Disconnect the cable from the positive post of both
batteries.
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.

With Portable Starting Unit
There are many types of these units available. Follow the
manufacturer’s instructions for necessary precautions
and operation.
CAUTION!
It is very important that the starting unit operating
voltage does not exceed 12-Volts DC or damage to
battery, starter motor, alternator, or electrical system
may occur.
FREEING A STUCK VEHICLE
If the vehicle becomes stuck in snow, sand, or mud, it can
often be moved by a rocking motion. Move the shift lever
rhythmically between DRIVE and REVERSE while ap-
plying slight pressure to the accelerator.In general, the least amount of accelerator pedal pressure
to maintain the rocking motion without spinning the
wheels or racing the engine, is most effective. Racing the
engine or spinning the wheels, due to the frustration of
not freeing the vehicle, may lead to transmission over-
heating and failure. Allow the engine to idle with the
shift lever in NEUTRAL for at least one minute after
every five rocking-motion cycles. This will minimize
overheating and reduce the risk of transmission failure
during prolonged efforts to free a stuck vehicle.
EMERGENCY TOW HOOKS — IF EQUIPPED
Your vehicle may be equipped with emergency tow
hooks.
NOTE:
For off-road recovery, it is recommended to use
both of the front tow hooks to minimize the risk of
damage to the vehicle.

WARNING!
•Chains are not recommended for freeing a stuck
vehicle. Chains may break, causing serious injury
or death.
•Stand clear of vehicles when pulling with tow
hooks. Tow straps and chains may break, causing
serious injury.
CAUTION!
Tow hooks are for emergency use only to rescue a
vehicle stranded off-road. Do not use tow hooks for
tow truck hookup or highway towing. You could
damage your vehicle.
TOWING A DISABLED VEHICLE
Proper towing or lifting equipment is required to prevent
damage to your vehicle. Use only tow bars and other
equipment designed for the purpose, following equip-
ment manufacturer’s instructions. Use of safety chains is
mandatory. Attach a tow bar or other towing device to
the main structural members of the vehicle—not to
bumpers or associated brackets. State and local laws
applying to vehicles under tow must be observed.
4-Wheel Drive Vehicles
CAUTION!
To avoid damage to the transfer case while towing,
always use one of the following methods.
WHAT TO DO IN EMERGENCIES 331

Page 334 of 429

NOTE:The transfer case must be in the neutral position,
and the transmission must be in PARK (automatic trans-
mission), or in gear (manual transmission) to tow a
4-Wheel Drive vehicle with one end of the vehicle raised.
The manufacturer recommends towing with all wheels
OFF the ground. Acceptable methods are to tow the
vehicle on a flatbed or with one end of vehicle raised and
the opposite end on a towing dolly.
2–Wheel Drive Vehicles
Provided that the transmission is operable, tow with the
transmission in NEUTRAL and the ignition key in the
OFF position along with the front wheels raised and the
rear wheels on the ground. Speed must not exceed
30 mph (50 km/h) and distance must not exceed 15 miles
(25 km).
CAUTION!
Towing faster than 30 mph (50 km/h) or for more than
15 miles (25 km) can cause severe damage to the
transmission.
If the vehicle is to be towed faster than 30 mph (50 km/h)
or more than 15 miles (25 km) the vehicle must be towed
with the rear wheels raised and the front wheels on the
ground. It may also be towed on a flatbed or with the
front wheels raised and the rear wheels on a dolly.
