438 STARTING AND OPERATING
Off-Road Driving Tips
Care should be taken when attempting to climb steep hills or
driving diagonally across a hill or slope. If natural obstacles
force you to travel diagonally up or down a hill, choose a
mild angle and keep as little side tilt as possible. Keep the
vehicle moving and make turns slowly and cautiously.
If you must back down a hill, back straight down using
REVERSE gear. Never back down in NEUTRAL or diago-
nally across the hill.
When driving over sand, mud, and other soft terrain, shift to
low gear and drive steadily. Apply the accelerator slowly to
avoid spinning the wheels.
Do not reduce the tire pressures for this type of driving.
• Driving through standing water may cause damage to
your vehicle’s drivetrain components. Always inspect
your vehicle’s fluids (i.e., engine oil, transmission, axle,
etc.) for signs of contamination (i.e., fluid that is milky
or foamy in appearance) after driving through standing
water. Do not continue to operate the vehicle if any
fluid appears contaminated, as this may result in
further damage. Such damage is not covered by the
New Vehicle Limited Warranty.
• Getting water inside your vehicle’s engine can cause it to lock up and stall out, and cause serious internal
damage to the engine. Such damage is not covered by
the New Vehicle Limited Warranty. CAUTION!

Side Marker Lamps (Dual Rear Wheels) — If Equipped Side Marker Lamp Locations
1. Push rearward on the side marker lamp assembly.
2. Pull the entire assembly from the fender.
3. Turn the socket ¼ turn counterclockwise and remove from assembly to access the bulb.
4. Pull the bulb straight out from socket.
5. Reverse the procedure for installation of the bulbs and housing.FUSES
WARNING!
• When replacing a blown fuse, always use an appro -
priate replacement fuse with the same amp rating as the
original fuse. Never replace a fuse with another fuse of
higher amp rating. Never replace a blown fuse with
metal wires or any other material. Do not place a fuse
inside a circuit breaker cavity or vice versa. Failure to
use proper fuses may result in serious personal injury,
fire and/or property damage.
• Before replacing a fuse, make sure that the ignition is off and that all the other services are switched off and/
or disengaged.
• If the replaced fuse blows again, contact an authorized dealer.
• If a general protection fuse for safety systems (air bag system, braking system), power unit systems (engine
system, transmission system) or steering system blows,
contact an authorized dealer.

JACKING AND TIRE CHANGING NOTE:
If your vehicle is equipped with an air suspension system,
there is a feature which allows the automatic leveling to be
disabled to assist with changing a tire.
This feature can be activated through the Uconnect system.
Refer to “Uconnect Settings” in “Multimedia” for further
information.
WARNING!
• Do not attempt to change a tire on the side of the vehicle close to moving traffic. Pull far enough off the road to
avoid the danger of being hit when operating the jack
or changing the wheel.
• Being under a jacked-up vehicle is dangerous. The vehicle could slip off the jack and fall on you. You
could be crushed. Never put any part of your body
under a vehicle that is on a jack. If you need to get
under a raised vehicle, take it to a service center where
it can be raised on a lift.
• Never start or run the engine while the vehicle is on a jack.
• The jack is designed to be used as a tool for changing tires only. The jack should not be used to lift the
vehicle for service purposes. The vehicle should be
jacked on a firm level surface only. Avoid ice or slip -
pery areas.

Jacking Instructions
Jack Warning Label
WARNING!
Carefully follow these tire changing warnings to help
prevent personal injury or damage to your vehicle:
• Always park on a firm, level surface as far from the edge of the roadway as possible before raising the
vehicle.
• Turn on the Hazard Warning flasher.
• Block the wheel diagonally opposite the wheel to be raised.
• Apply the parking brake firmly and set the transmis -
sion in PARK.
• Never start or run the engine with the vehicle on a jack.
• Do not let anyone sit in the vehicle when it is on a jack.
• Do not get under the vehicle when it is on a jack. If you need to get under a raised vehicle, take it to a service
center where it can be raised on a lift.
• Only use the jack in the positions indicated and for lifting this vehicle during a tire change.
• If working on or near a roadway, be extremely careful of motor traffic.• To assure that spare tires, flat or inflated, are securelystowed, spares must be stowed with the valve stem
facing the ground.

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 may be covered with a protective
cap if equipped. Lift up on the cap to gain access to the posi-
tive battery post. Do not jump off fuses. Only jump directly
off positive post which has a positive (+) symbol on or
around the post.
Positive Battery Post 1. Apply the parking brake, shift the automatic transmis-
sion into PARK and turn the ignition OFF.
2. Turn off the heater, radio, and all unnecessary electrical accessories.
WARNING!
• Take care to avoid the radiator cooling fan whenever the hood is raised. It can start 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.

3. If using another vehicle to jump start the battery, park thevehicle within the jumper cables’ reach, apply the
parking brake and make sure the ignition is OFF.
Jump Starting Procedure
Connecting The Jumper Cables
1. Connect the positive (+) end of the jumper cable to the
positive (+) post of the discharged vehicle.
NOTE:
Do not jump off fuses. Only jump directly off positive
post.
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 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 allow vehicles to touch each other as this could
establish a ground connection and personal injury could
result.
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.
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.

491
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.
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 engine ground of the vehicle with the discharged
battery.
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 positive (+) post of the vehicle with the
discharged battery.
If frequent jump starting is required to start your vehicle you
should have the battery and charging system inspected at an
authorized dealer.
CAUTION!
Do not connect jumper cable to any of the fuses on the
positive battery terminal. The resulting electrical current
will blow the fuse.
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.
