NOTE:Vehicles equipped with air suspension must be
placed in Transport mode before tying them down (from
the body) on a trailer or flatbed truck. Refer to “Air
Suspension – If Equipped” 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 instruc-
tions may cause fault codes to be set and/or cause loss of
proper tie-down tension.
Recreational Towing — Two-Wheel Drive Models
DO NOT flat tow this vehicle. Damage to the drivetrain
will result.
Recreational towing (for two-wheel drive models) is
allowedONLYif the rear wheels areOFFthe ground.
This may be accomplished using a tow dolly or vehicle
trailer. If using a tow dolly, follow this procedure:
1. Properly secure the dolly to the tow vehicle, following
the dolly manufacturer’s instructions.
NOTE:If vehicle is equipped with air suspension, ensure
the vehicle is set to Normal Ride Height.
2. Drive the rear wheels onto the tow dolly.
3. Firmly apply the parking brake. Place automatic trans-
mission in PARK, manual transmission in gear (not in
NEUTRAL).
4. Properly secure the rear wheels to the dolly, following
the dolly manufacturer’s instructions.
5. Turn the ignition switch to the OFF position and
remove the Key Fob.
6. Install a suitable clamping device, designed for tow-
ing, to secure the front wheels in the straight position.

5. Release the parking brake.
6. Shift the transmission into REVERSE.
7. Release the brake pedal (and clutch pedal on manual
transmissions) for five seconds and ensure that there is
no vehicle movement.
8. Repeat steps 7 and 8 with automatic transmission in
DRIVE or manual transmission in first gear.
9. Shift the transmission to NEUTRAL. Firmly apply the
parking brake. Turn OFF the engine. For vehicles with
Keyless Enter-N-Go™, press and hold the ENGINE
START/STOP button until the engine shuts off.
10. Shift the transmission into PARK or place manual
transmission in gear (NOT in Neutral). On 8-speed
transmissions the shifter will automatically select
PARK when the engine is turned off.
11. Turn the ignition switch to the OFF position, then
cycle the key or the Keyless Enter-N-Go™ button to
the RUN position and back to the OFF position.
12. Attach the vehicle to the tow vehicle using a suitable
tow bar.
13. Release the parking brake.
NOTE:With electronic shift transfer case:
•Steps 2 through 4 are requirements that must be met
before pressing the NEUTRAL (N) button, and must
continue to be met until the shift has been completed.
If any of these requirements are not met before press-
ing the NEUTRAL (N) button or are no longer met
during the shift, the NEUTRAL (N) indicator light will
flash continuously until all requirements are met or
until the NEUTRAL (N) button is released.

•The ignition switch must be in the ON/RUN position
for a shift to take place and for the position indicator
lights to be operable. If the ignition switch is not in the
ON/RUN position, the shift will not take place and no
position indicator lights will be on or flashing.
•A flashing NEUTRAL (N) position indicator light
indicates that shift requirements have not been met.
•If the vehicle is equipped with air suspension, the
engine should be started and left running for a mini-
mum of 60 seconds (with all the doors closed) at least
once every 24 hours. This process allows the air
suspension to adjust the vehicle’s ride height to com-
pensate for temperature effects.
Shifting Out Of NEUTRAL (N)
Use the following procedure to prepare your vehicle for
normal usage.
1. Bring the vehicle to a complete stop, leaving it con-
nected to the tow vehicle.
2. Firmly apply the parking brake.
3. Press and hold the brake pedal.
4. Start the engine. Shift the transmission into NEU-
TRAL. Depress the clutch pedal on a manual trans-
mission.
•With manual shift transfer case, shift the transfer
case lever to the desired position.
•With electronic shift transfer case with rotary selector
switch, press and hold the transfer case NEUTRAL (N)
button until the NEUTRAL (N) indicator light turns
off. After the NEUTRAL (N) indicator light turns off,
release the NEUTRAL (N) button. After the NEUTRAL

the shift, the NEUTRAL (N) indicator light will flash
continuously until all requirements are met or until the
button is released.
•The ignition switch must be in the ON/RUN position
for a shift to take place and for the position indicator
lights to be operable. If the ignition switch is not in the
ON/RUN position, the shift will not take place and no
position indicator lights will be on or flashing.
•A flashing NEUTRAL (N) position indicator light
indicates that shift requirements have not been met.

HAZARD WARNING FLASHERS
The Hazard Warning flasher switch is located on the
upper switch bank just below the radio.
Press the switch to turn on the Hazard Warning
flasher. When the switch is activated, all direc-
tional turn signals will flash on and off to warn oncoming
traffic of an emergency. Press the switch a second time to
turn off the Hazard Warning flashers.
This is an emergency warning system and it should not
be used when the vehicle is in motion. Use it when your
vehicle is disabled and it is creating a safety hazard for
other motorists.
When you must leave the vehicle to seek assistance, the
Hazard Warning flashers will continue to operate even
though the ignition is placed in the OFF position.
NOTE:With extended use the Hazard Warning flashers
may wear down your battery.
IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the
potential 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.
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.

Preparations
1. Park the vehicle on a firm, level surface. Avoid ice or
slippery areas.
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.
2. Turn on the Hazard Warning flasher.
3. Set the parking brake.
4. Place the shift lever into PARK. On four-wheel drive
vehicles, shift the transfer case to the 4L position.
5. Turn the ignition OFF.
Block both the front and rear of the wheel diagonally
opposite the jacking position. For example, if the right
front wheel is being changed, block the left rear wheel.
NOTE:Passengers should not remain
in the vehicle when the vehicle is
being jacked.

WARNING!
•Take care to avoid the radiator cooling fan when-
ever 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.
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 electri-
cal accessories.
3. 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.
