JUMP-STARTING
• If your vehicle has a discharged battery it can be jump-started using aset 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.
NOTE: When using a portable battery booster pack follow the
manufacturer’s operating instructions and precautions.
Preparations for Jump-Start
• The battery in your vehicle is located in the front of the engine compartment, behind the left headlight assembly.
NOTE: The positive battery post is covered with a protective cap. Lift up on
the cap to gain access to the positive battery post.
• Set the parking brake, shift the automatic transmission into PARK andturn the ignition to LOCK.
• Turn off the heater, radio, and all unnecessary electrical accessories.
• 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.
Jump-Starting Procedure
• Connect the positive (+) end of the jumper cable to the positive (+) postof the discharged vehicle.
WHAT TO DO IN EMERGENCIES
89

• Connect the opposite end of the positive (+) jumper cable to the positive(+) post of the booster battery.
• Connect the negative end (-) of the jumper cable to the negative (-) post of the booster battery.
• 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.
• 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:
• Disconnect the negative (-) jumper cable from the engine ground of the vehicle with the discharged battery.
• Disconnect the negative end (-) of the jumper cable from the negative (-) post of the booster battery.
• Disconnect the opposite end of the positive (+) jumper cable from the positive (+) post of the booster battery.
• 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 inspected at your authorized dealer.
CAUTION!
• Do not use a portable battery booster pack or any other boostersource with a system voltage greater than 12 Volts or damage to the
battery, starter motor, alternator or electrical system may occur.
• Failure to follow these procedures could result in damage to the charging system of the booster vehicle or the discharged vehicle.
• 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.
WARNING!
• When temperatures are below the freezing point, electrolyte in adischarged battery may freeze. Do not attempt jump-starting
because the battery could rupture or explode and cause personal
injury. Battery temperature must be brought above the freezing
point before attempting a jump-start.

WARNING!(Continued)
• Take care to avoid the radiator cooling fan whenever the hood israised. It can start anytime the ignition switch is on. You can be
injured by moving fan blades.
• Remove any metal jewelry, such as watch bands or bracelets, that might make an inadvertent electrical contact. You could be severely
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.
• Do not allow vehicles to touch each other as this could establish a ground connection and personal injury could result.
• Failure to follow this procedure could result in personal injury or property damage due to battery explosion.
• 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.
SHIFT LEVER OVERRIDE
• If a malfunction occurs and theshift lever cannot be moved out of
the PARK position, you can use
the following procedure to
temporarily move the shift lever:
• To access the shift lever override, remove the override cover
located on the PRNDL bezel, next
to the shift lever.
• Firmly set the parking brake.
• Turn the ignition switch to the ACC or ON position without
starting the engine.
• Press and maintain firm pressure on the brake pedal.
• Using a screwdriver or similar tool, press and hold the override tab through the access port on the center console.
• Move the shift lever into the NEUTRAL position.
• The vehicle may then be started in NEUTRAL.
• Reinstall the override cover.

FREEING A STUCK VEHICLE
• If your vehicle becomes stuck in mud, sand or snow, it can often bemoved by a rocking motion. Turn your steering wheel right and left to
clear the area around the front wheels. Then shift back and forth
between REVERSE and DRIVE. Using minimal accelerator pedal pressure
to maintain the rocking motion, without spinning the wheels, is most
effective.
NOTE: If your vehicle is equipped with Traction Control or Electronic
Stability Control (ESC), turn the system OFF before attempting to “rock” the
vehicle.
CAUTION!
• Racing the engine or spinning the wheels may lead to transmission overheating 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.
• When “rocking” a stuck vehicle by moving between REVERSE and DRIVE, 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
transmission shifting occurring).
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.
