3. Connect the negative end (-) of the jumper cable to the
negative (-) post of the booster battery.
4. Connect the opposite end of the negative (-) jumper
cable to a good engine ground (exposed metal part of
the discharged vehicle’s engine) away from the battery
and the fuel injection system.
WARNING!Do not connect the cable to the negative post (-) of the
discharged battery. The resulting electrical spark
could cause the battery to explode and could result in
personal injury.
5. 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. Once the engine is started, remove the jumper cables in
the reverse sequence:
6. Disconnect the negative (-) jumper cable from the
engine ground of the vehicle with the discharged
battery.
7. Disconnect the negative end (-) of the jumper cable
from the negative (-) post of the booster battery.
8. Disconnect the opposite end of the positive (+) jumper
cable from the positive (+) post of the booster battery.
9. Disconnect the positive (+) end of the jumper cable
from the positive (+) post of the discharged vehicle.
If frequent jump-starting is required to start your vehicle
you should have the battery and charging system in-
spected at your authorized dealer.

CAUTION!Accessories that can be plugged into the vehicle
power outlets draw power from the vehicle’s battery,
even when not in use (i.e., cellular phones, etc.).
Eventually, if plugged in long enough, the vehicle’s
battery will discharge sufficiently to degrade battery
life and/or prevent the engine from starting.
FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand or snow, it
can often be moved using a rocking motion. Turn the
steering wheel right and left to clear the area around the
front wheels. Then shift back and forth between DRIVE
and REVERSE (with automatic transmission) or 2nd gear
and REVERSE (with manual transmission), while gently pressing the accelerator. Use the least amount of accel-
erator pedal pressure that will maintain the rocking
motion, without spinning the wheels, or racing the
engine.
CAUTION!Racing the engine or spinning the wheels may lead to
transmission overheating and failure. Allow the en-
gine 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.
NOTE: Press the  ESC Off  switch, to place the Electronic
Stability Control (ESC) system in  Partial Off  mode,
before rocking the vehicle. Refer to “Electronic Brake552 WHAT TO DO IN EMERGENCIES

Control” in “Starting And Operating” for further infor-
mation. Once the vehicle has been freed, press the  ESC
Off  switch again to restore  ESC On  mode.
CAUTION!• When “rocking” a stuck vehicle by shifting be-
tween DRIVE/2nd gear and REVERSE, do not spin
the wheels faster than 15 mph (24 km/h), or drive-
train damage may result.
• Revving 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 30 mph (48 km/h) while in gear (no trans-
mission shifting occurring). WARNING!Fast spinning tires can be dangerous. Forces gener-
ated by excessive wheel speeds may cause damage, or
even failure, of the axle and tires. A tire could
explode and injure someone. Do not spin your vehi-
cle’s wheels faster than 30 mph (48 km/h) or for
longer than 30 seconds continuously without stop-
ping when you are stuck and do not let anyone near
a spinning wheel, no matter what the speed.

EMERGENCY TOW HOOKS — IF EQUIPPED
If your vehicle is equipped with tow hooks, they are
mounted in the front and the rear.
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. Always use an appropriately rated
tow strap.
WARNING!• Do not use a chain for freeing a stuck vehicle.
Chains may break, causing serious injury or death.
• Stand clear of vehicles when pulling with tow
hooks. Tow straps may become disengaged, caus-
ing 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. Tow straps are recommended
when towing the vehicle, chains may cause vehicle
damage.
SHIFT LEVER OVERRIDE
If a malfunction occurs and the shift lever cannot be
moved out of the PARK position, you can use the
following procedure to temporarily move the shift lever:
1. Turn the engine OFF.
2. Firmly apply the parking brake.554 WHAT TO DO IN EMERGENCIES

3. Using a small screwdriver or similar tool, remove the
shift lever override access cover (located to the right of
the shift lever).
4. Turn the ignition to the ACC or ON/RUN position,
but do not start the engine. 5. Press and maintain firm pressure on the brake pedal.
6. Insert the screwdriver or similar tool into the access
port, and push and hold the override release lever
down.
7. Move the shift lever to the NEUTRAL position.
8. The vehicle may then be started in NEUTRAL.
9. Reinstall the shift lever override access cover.

TOWING A DISABLED VEHICLE
This section describes procedures for towing a disabled
vehicle using a commercial wrecker service. If the trans-
mission and drivetrain are operable, disabled vehicles
may also be towed as described under “Recreational
Towing” in the “Starting And Operating” section.
Towing Condition Wheels OFF the Ground 4WD MODELS
Flat Tow NONE See instructions under “Recreational Towing”
• Automatic Transmission in PARK
• Manual Transmission in gear
( NOT in Neutral)
• Transfer Case in NEUTRAL
• To w i n forward direction
Wheel Lift or Dolly Tow Front NOT ALLOWED
Rear NOT ALLOWED
Flatbed ALL BEST METHOD556 WHAT TO DO IN EMERGENCIES

Proper towing or lifting equipment is required to prevent
damage to your vehicle. Use only tow bars and other
equipment designed for this purpose, following equip-
ment manufacturer ’s instructions. Use of safety chains is
mandatory. Attach a tow bar or other towing device to
main structural members of the vehicle, not to bumpers
or associated brackets. State and local laws regarding
vehicles under tow must be observed.
If you must use the accessories (wipers, defrosters, etc.)
while being towed, the ignition must be in the ON/RUN
position, not the ACC position.
If the vehicle’s battery is discharged, refer to “Shift Lever
Override” in “What To Do In Emergencies” for instruc-
tions on shifting the automatic transmission out of PARK
for towing. CAUTION!Do not use sling type equipment when towing. When
securing the vehicle to a flatbed truck, do not attach to
front or rear suspension components. Damage to your
vehicle may result from improper towing.
Without The Ignition Key
Special care must be taken when the vehicle is towed
with the ignition in the OFF position. The only approved
method of towing without the key fob is with a flatbed
truck. Proper towing equipment is necessary to prevent
damage to the vehicle.
6 WHAT TO DO IN EMERGENCIES 557

Four–Wheel Drive Models
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 the vehicle raised
and the opposite end on a towing dolly.
If flatbed equipment is not available and the transfer case
is operable, the vehicle may be towed (in the forward
direction, with ALL wheels on the ground), IF the
transfer case is in NEUTRAL (N) and the transmission is
in PARK (for automatic transmissions) or in gear ( NOT
in NEUTRAL , for manual transmissions). Refer to “Rec-
reational Towing” in “Starting And Operating” for de-
tailed instructions. CAUTION!• Front or rear wheel lifts should not be used. Inter-
nal transmission damage or transfer case will occur
if a front or rear wheel lift is used when towing.
• Failure to follow these towing methods can cause
severe transmission damage and/or transfer case.
Such damage is not covered by the New Vehicle
Limited Warranty.558 WHAT TO DO IN EMERGENCIES
