STARTING AND OPERATING 435
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 connectedto the tow vehicle.
2. Firmly apply the parking brake.
3. Press and hold the brake pedal.
4. Start the engine. Shift the transmission into NEUTRAL.
•With manual shift transfer case, shift the transfer caselever to the desired position.
•With electronic shift transfer case with rotary selector switch, push 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
(N) button has been released, the transfer case will shift
to the position indicated by the selector switch. • With electronic shift transfer case with push-button
selector switch, push and hold the switch for the
desired transfer case position, until the NEUTRAL (N)
indicator light turns off and the desired position indi -
cator light turns on.
NOTE:
When shifting out of transfer case NEUTRAL (N), turning
the engine OFF is not required, but may be helpful to avoid
gear clash. With the 8-speed automatic transmission, the
engine must remain running, since turning the engine OFF
will shift the transmission to PARK (and the transmission
must be in NEUTRAL for the transfer case to shift out of
NEUTRAL).
5. Turn the engine OFF. Shift automatic transmission into PARK. On 8-speed transmissions the shifter will auto -
matically select PARK when the engine is turned off.
6. Release the brake pedal.
7. Disconnect vehicle from the tow vehicle.
8. Start the engine.
9. Press and hold the brake pedal.

436 STARTING AND OPERATING
10. Release the parking brake.
11. Shift the transmission into gear, release the brake pedal,and check that the vehicle operates normally.
NOTE:
With electronic shift transfer case:
• Steps 3 and 4 are requirements that must be met before pushing the button to shift out of NEUTRAL (N), and must
continue to be met until the shift has been completed. If
any of these requirements are not met before pushing the
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 button is released.
• The ignition must be in the ON/RUN mode for a shift to take place and for the position indicator lights to be oper -
able. If the ignition is not in the ON/RUN mode, the shift
will not take place and no position indicator lights will be
on or flashing.
• A flashing NEUTRAL (N) position indicator light indi -
cates that shift requirements have not been met.DRIVING TIPS
Driving On Slippery Surfaces
Acceleration
Rapid acceleration on snow covered, wet, or other slippery
surfaces may cause the driving wheels to pull erratically to
the right or left. This phenomenon occurs when there is a
difference in the surface traction under the rear (driving)
wheels.
WARNING!
Rapid acceleration on slippery surfaces is dangerous.
Unequal traction can cause sudden pulling of the rear
wheels. You could lose control of the vehicle and
possibly have a collision. Accelerate slowly and carefully
whenever there is likely to be poor traction (ice, snow,
wet, mud, loose sand, etc.).

STARTING AND OPERATING 437
(Continued)
Driving Through Water
Driving through water more than a few inches/centimeters
deep will require extra caution to ensure safety and prevent
damage to your vehicle.
Flowing/Rising Water
Shallow Standing Water
Although your vehicle is capable of driving through shallow
standing water, consider the following Cautions and Warn-
ings before doing so.
WARNING!
Do not drive on or across a road or path where water is
flowing and/or rising (as in storm run-off). Flowing
water can wear away the road or path's surface and cause
your vehicle to sink into deeper water. Furthermore,
flowing and/or rising water can carry your vehicle away
swiftly. Failure to follow this warning may result in
injuries that are serious or fatal to you, your passengers,
and others around you.
WARNING!
• Driving through standing water limits your vehicle’s traction capabilities. Do not exceed 5 mph (8 km/h)
when driving through standing water.
• Driving through standing water limits your vehicle’s braking capabilities, which increases stopping
distances. Therefore, after driving through standing
water, drive slowly and lightly press on the brake pedal
several times to dry the brakes.
• Failure to follow these warnings may result in injuries that are serious or fatal to you, your passengers, and
others around you.
CAUTION!
• Always check the depth of the standing water before driving through it. Never drive through standing water
that is deeper than the bottom of the tire rims mounted
on the vehicle.
• Determine the condition of the road or the path that is under water and if there are any obstacles in the way
before driving through the standing water.
• Do not exceed 5 mph (8 km/h) when driving through standing water. This will minimize wave effects.

STARTING AND OPERATING 439
After Driving Off-Road
Off-road operation puts more stress on your vehicle than
does most on-road driving. After going off-road, it is always
a good idea to check for damage. That way you can get any
problems taken care of right away and have your vehicle
ready when you need it.
• Completely inspect the underbody of your vehicle. Checktires, body structure, steering, suspension, and exhaust
system for damage.
• Inspect the radiator for mud and debris and clean as required.
• Check threaded fasteners for looseness, particularly on the chassis, drivetrain components, steering, and suspension.
Retighten them, if required, and torque to the values spec -
ified in the Service Manual.
• Check for accumulations of plants or brush. These things could be a fire hazard. They might hide damage to fuel
lines, brake hoses, axle pinion seals, and propeller shafts. • After extended operation in mud, sand, water, or similar
dirty conditions, have the radiator, fan, brake rotors,
wheels, brake linings, and axle yokes inspected and
cleaned as soon as possible.
• If you experience unusual vibration after driving in mud, slush or similar conditions, check the wheels for impacted
material. Impacted material can cause a wheel imbalance
and freeing the wheels of it will correct the situation.
WARNING!
Abrasive material in any part of the brakes may cause
excessive wear or unpredictable braking. You might not
have full braking power when you need it to prevent a
collision. If you have been operating your vehicle in
dirty conditions, get your brakes checked and cleaned as
necessary.

Preparations For Jacking
1. Park the vehicle on a firm, level surface. Avoid ice or slip-
pery areas.
2. Place the gear selector into PARK. On four-wheel drive vehicles, shift the transfer case to the 4L position.
3. Turn on the Hazard Warning flasher.
4. Apply the parking brake.
5. Turn the ignition OFF. 6. 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.
Wheel Blocked
NOTE:
Passengers should not remain in the vehicle when the
vehicle is being jacked.
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 being hit when operating the jack or changing the
wheel.
