JUMP-STARTING
If your vehicle has a discharged battery it can be jump-started using a set of jumper
cables and a battery in another vehicle or by using a portable battery booster pack.
Jump-starting can be dangerous if done improperly so please follow the procedures
in this section carefully.
WARNING!
Do not attempt jump-starting if the battery is frozen. It could rupture or explode
and cause personal injury.
CAUTION!
Do not use a portable battery booster pack or any other booster source with a
system voltage greater than 12 Volts or damage to the battery, starter motor,
alternator or electrical system may occur.
NOTE:
When using a portable battery booster pack follow the manufacturer's operating
instructions and precautions.

206

Preparations For Jump-Start
The battery in your vehicle is located under the passenger's front seat. There are
remote locations located under the hood to assist in jump-starting.
WARNING!
• Take care to avoid the radiator cooling fan whenever the hood is raised. It canstart anytime the ignition switch is ON. You can be injured by moving fan
blades.
• Remove any metal jewelry such as rings, watch bands and bracelets that could
make an inadvertent electrical contact. You could be seriously injured.
• Batteries contain sulfuric acid that can burn your skin or eyes and generate
hydrogen gas which is flammable and explosive. Keep open flames or sparks
away from the battery.
NOTE:
Be sure that the disconnected ends of the cables do not touch while still connected
to the either vehicle.
1. Set the parking brake, shift the automatic transmission into PARK and turn the ignition to LOCK.
2. Turn off the heater, radio, and all unnecessary electrical accessories.
3. Remove the protective cover over the remote positive (+)battery post. Pull upward
on the cover to remove it.
4. If using another vehicle to jump-start the battery, park the vehicle within the jumper cables reach, set the parking brake and make sure the ignition is OFF.

WARNING!
Do not allow vehicles to touch each other as this could establish a ground
connection and personal injury could result.
Jump-Starting Procedure
WARNING!
Failure to follow this jump-starting procedure could result in personal injury or
property damage due to battery explosion.
CAUTION!
Failure to follow these procedures could result in damage to the charging system
of the booster vehicle or the discharged vehicle.
NOTE:
Make sure at all times that unused ends of jumper cables are not contacting each
other or either vehicle while making connections.
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 electrical 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
208

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 cables in 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 discharged 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 suffi-
ciently to degrade battery life and/or prevent the engine from starting.
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.
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, causing serious injury.
WHAT TO DO IN EMERGENCIES
209

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.
MANUAL PARK RELEASE
WARNING!
Always secure your vehicle by fully applying the parking brake, before activating
the Manual Park Release. Activating the Manual Park Release will allow your
vehicle to roll away if it is not secured by the parking brake or by proper connection
to a tow vehicle. Activating the Manual Park Release on an unsecured vehicle
could lead to serious injury or death for those in or around the vehicle.
In order to move the vehicle in cases where the transmission will not shift out of
PARK (such as a dead battery), a Manual Park Release is available.
Follow these steps to use the Manual Park Release:
1. Firmly apply the parking brake.
2. Open the center console and locate the Manual Park Release cover, remove it by snapping the cover away from the console hinges.
3. Using a screwdriver or similar tool, push the metal latch in towards the
tether strap.

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 “Electronic
Brake Control” in “Starting And Operating” in the Owners Manual on the DVD 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 prolonged efforts to free a stuck
vehicle.
WARNING!
Fast spinning tires can be dangerous. Forces generated 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 vehicle's wheels faster than 30 mph (48 km/h)
or for longer than 30 seconds continuously without stopping when you are stuck
and do not let anyone near a spinning wheel, no matter what the speed.
CAUTION!
• When “rocking” a stuck vehicle by shifting between DRIVE and REVERSE, donot 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 transmission shifting occurring).
