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.

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.

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.

4. Using the screwdriver or similar tool, push the ManualPark Release lever locking tab (just below the middle of
the lever) to the right.
5. While holding the locking tab in the disengaged position, pull the tether strap to rotate the lever rearward, until it
locks in place pointing towards the driver's seat. Release
the locking tab and verify that the Manual Park Release
lever is locked in the released position.
6. The vehicle is now out of PARK and can be towed. Release the parking brake only when the vehicle is
securely connected to a tow vehicle.
To Reset The Manual Park Release:
1. Push the locking tab to the right, to unlock the lever.
2. Rotate the Manual Park Release lever forward to its orig -
inal position, until the locking tab snaps into place to
secure the lever.
3. Pull gently on the tether strap to confirm that the lever is locked in its stowed position.
4. Re-install the access cover.IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the poten -
tial for overheating by taking the appropriate action.
• On the highways — slow down.
• In city traffic — while stopped, place the transmission in NEUTRAL, but do not increase the engine idle speed while
preventing vehicle motion with the brakes.
NOTE:
There are steps that you can take to slow down an impending
overheat condition:
• If your air conditioner (A/C) is on, turn it off. The A/C system adds heat to the engine cooling system and turning
the A/C off can help remove this heat.
• You can also turn the temperature control to maximum heat, the mode control to floor and the blower control to
high. This allows the heater core to act as a supplement to
the radiator and aids in removing heat from the engine
cooling system.

494 IN CASE OF EMERGENCY
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 ofaccelerator pedal pressure that will maintain the rocking
motion, without spinning the wheels or racing the engine.
NOTE:
• For trucks equipped with an 8–speed transmission, 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.
• Push the "ESC Off" switch, to place the Electronic Stability Control (ESC) system in "Partial Off" mode, before rocking
the vehicle. Refer to “Electronic Brake Control” in “Safety”
for further information. Once the vehicle has been freed,
push the "ESC Off" switch again to restore "ESC On" mode.
WARNING!
You or others can be badly burned by hot engine coolant
(antifreeze) or steam from your radiator. If you see or
hear steam coming from under the hood, do not open the
hood until the radiator has had time to cool. Never try to
open a cooling system pressure cap when the radiator or
coolant bottle is hot.
CAUTION!
Driving with a hot cooling system could damage your
vehicle. If the temperature gauge reads HOT (H), pull
over and stop the vehicle. Idle the vehicle with the air
conditioner turned off until the pointer drops back into
the normal range. If the pointer remains on HOT (H),
and you hear continuous chimes, turn the engine off
immediately and call for service.
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.
