NOTE: Passengers should not remain in the vehicle
when the vehicle is being jacked.
7. For vehicles equipped with Quadra-Lift, refer to “Quadra-Lift — If Equipped” in “Starting And Oper-
ating” for further information on disabling automatic
leveling.Jacking Instructions

606 WHAT TO DO IN EMERGENCIES

Connecting The Jumper Cables
1. Connect the positive(+)end of the jumper cable to the
remote positive (+)post of the discharged vehicle.
2. Connect the opposite end of the positive (+)jumper
cable to the positive (+)post of the booster battery.
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 jumper cable to the negative (-)
post of the discharged battery. The resulting electri-
cal spark could cause the battery to explode and
could result in personal injury. Only use the specific
ground point, do not use any other exposed metal
parts.
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.

WHAT TO DO IN EMERGENCIES 617

CAUTION!
Do not run the booster vehicle engine above 2000 rpm
since it provides no charging benefit, wastes fuel and
can damage booster vehicle engine.
6. Once the engine is started, remove the jumper cablesin the reverse sequence:
Disconnecting The Jumper Cables
1. Disconnect the negative (-)end of the jumper cable
from the remote negative (-)post of the discharged
vehicle.
2. Disconnect the opposite end of the negative (-)jumper
cable from the negative (-)post of the booster battery.
3. Disconnect the positive (+)end of the jumper cable
from the positive (+)post of the booster battery. 4. Disconnect the opposite end of the positive
(+)jumper
cable from the remote positive (+)post of the dis-
charged vehicle.
5. Reinstall the protective cover over the remote positive (+) post of the discharged vehicle.
If frequent jump-starting is required to start your vehicle
you should have the battery and charging system tested
at your authorized dealer.
CAUTION!
Accessories plugged into the vehicle power outlets
draw power from the vehicle’s battery, even when not
in use (i.e., cellular devices, etc.). Eventually, if
plugged in long enough without engine operation,
the vehicle’s battery will discharge sufficiently to
degrade battery life and/or prevent the engine from
starting.
618 WHAT TO DO IN EMERGENCIES

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. Push and hold the lock button on the gear
selector. Then shift back and forth between DRIVE and
REVERSE while gently pressing the accelerator.
NOTE:Shifts between DRIVE and REVERSE can only be
achieved at wheel speeds of 5 mph (8 km/h) or less.
Whenever the transmission remains in NEUTRAL for
more than two seconds, you must press the brake pedal
to engage DRIVE or REVERSE.
Use the least amount of accelerator pedal pressure that
will maintain the rocking motion without spinning the
wheels or racing the engine. NOTE:
Push the ESC Off switch (if necessary), to place
the Electronic Stability Control (ESC) system in Partial
Off mode, before rocking the vehicle. Refer to “Elec-
tronic Brake Control” in “Starting And Operating” for
further information. Once the vehicle has been freed,
push the ESC Off switch again to restore ESC On
mode.
CAUTION!
• Racing the engine or spinning the wheels may lead
to transmission overheating and failure. Allow the
engine 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 pro-
longed efforts to free a stuck vehicle.

WHAT TO DO IN EMERGENCIES 619

CAUTION!(Continued)
•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.
620 WHAT TO DO IN EMERGENCIES

TOWING A DISABLED VEHICLE
This section describes procedures for towing a disabled
vehicle using a commercial towing 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.NOTE:
Vehicles equipped with Quadra-Lift must be
placed in Transport mode, before tying them down (from
the body) on a trailer or flatbed truck. Refer to the section
on Quadra-Lift for more information. If the vehicle
cannot be placed in Transport mode (for example, engine
will not run), tie-downs must be fastened to the axles (not
to the body). Failure to follow these instructions may
cause fault codes to be set and/or cause loss of proper
tie-down tension.

WHAT TO DO IN EMERGENCIES 625

CAUTION!(Continued)
Damage to your vehicle may result from improper
towing.
Two-Wheel Drive Models
The manufacturer recommends towing your vehicle with
all four wheels OFFthe ground using a flatbed.
If flatbed equipment is not available, and the transmis-
sion is operable, the vehicle may be towed (with rear
wheels on the ground) under the following conditions:
• The transmission must be in NEUTRAL. Refer to
Manual Park Release in this section for instructions
on shifting the transmission to NEUTRAL when the
engine is off.
• The towing speed must not exceed 30 mph (48 km/h).
• The towing distance must not exceed 30 miles (48 km). If the transmission is not operable, or the vehicle must be
towed faster than 30 mph (48 km/h) or farther than 30
miles (48 km), tow with the rear wheels
OFFthe ground.
Acceptable methods are to tow the vehicle on a flatbed,
or with the front wheels raised and the rear wheels on a
towing dolly, or (when using a suitable steering wheel
stabilizer to hold the front wheels in the straight position)
with the rear wheels raised and the front wheels on the
ground.
CAUTION!
Towing faster than 30 mph (48 km/h) or farther than
30 miles (48 km) with rear wheels on the ground can
cause severe transmission damage. Damage from
improper towing is not covered under the New
Vehicle Limited Warranty.
