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 the remote negative (-)post of the vehicle with
the discharged battery.
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
remote negative (-)post of the discharged vehicle.
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 remote positive (+)post of the discharged
vehicle.
10. Reinstall the protective cover over the remote posi- tive (+)battery post of the discharged vehicle.
If frequent jump-starting is required to start your vehicle

WHAT TO DO IN EMERGENCIES 551

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 while gently pressing the accelerator. Use
the least amount of accelerator pedal pressure that will
maintain the rocking motion without spinning the
wheels or racing the engine.NOTE:
Press the ESC Off switch, to place the Electronic
Stability Control (ESC) system in Partial Offmode,
before rocking the vehicle. Refer to “Electronic Brake
Control” in “Starting And Operating” for further infor-
mation. Once the vehicle has been freed, press the ESC
Off switch again to restore ESC Onmode.
CAUTION!
Racing the engine or spinning the wheels may lead to
transmission overheating and failure. Allow the en-
gine to idle with the transmission 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.
552 WHAT TO DO IN EMERGENCIES

CAUTION!
•When “rocking” a stuck vehicle by shifting be-
tween DRIVE and REVERSE, do not spin the
wheels faster than 15 mph (24 km/h), or drivetrain
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

WARNING! (Continued)
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, there will be
one in the rear and two mounted on the front of the
vehicle. The rear hook will be located on the driver’s side
of the vehicle.
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.

WHAT TO DO IN EMERGENCIES 553

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.
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.
3. Remove the rubber liner from the cupholder (located next to the shifter on the center console).
4.
Using a small screwdriver or similar tool, remove the
shift lever override access cover (located on the bottom
of the cupholder).
554 WHAT TO DO IN EMERGENCIES

5. Press and maintain firm pressure on the brake pedal.
6.
Insert the screwdriver or similar tool into the access hole,
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 and
cupholder liner.
TOWING A DISABLED VEHICLE
The manufacturer requires towing your vehicle with all
four wheels OFFthe ground using a flatbed.
CAUTION!
•Towing this vehicle using any other method could
result in extensive damage to the transfer case
and/or transmission.
• Such damage is not covered by the New Vehicle
Limited Warranty.
