®
• The transfer case provides four mode positions: 2H (Two-wheel drive high
range), 4H (Four-wheel drive high
range), N (Neutral), and 4L
(Four-wheel drive low range).
• The transfer case is intended to be driven in the 2H position for normal
street and highway conditions such
as hard-surfaced roads.
• Shifting between 2H and 4H can be made with the vehicle stopped or in
motion. Shift the transfer case lever
firmly to 4H at any speed up to
50 mph (80 km/h).
• Shifting between 4H and 4L can be made with the vehicle rolling at 2 to
3 mph (3 to 5 km/h). Shift the
automatic transmission into
NEUTRAL or fully depress the clutch
pedal on a manual transmission. Shift
the transfer case lever firmly to 4L (do
not pause with the transfer case in
NEUTRAL). Once the shift is
completed, place the automatic
transmission into DRIVE or release
the clutch pedal on a manual
transmission.
NOTE: To enhance off-road performance
in 4L mode, manual transmission vehicles will start regardless of whether or not the
clutch pedal is depressed.

OVERDRIVE OFF SWITCH
• Overdrive can be locked out bypressing the O/D OFF switch located
on the center console. An indicator
light in the instrument cluster will
illuminate to show that the switch has
been activated. Pressing the switch a
second time restores the Overdrive
function.
• When frequent transmission shifting occurs while using Overdrive, such as
when operating the vehicle under
heavy load conditions (for example, in
hilly terrain, strong head winds, or
trailer towing), turning off overdrive will
improve performance and extend
transmission life by reducing
excessive shifting and heat buildup.
RECREATIONAL TOWING
(BEHIND MOTORHOME)
Towing - Two-Wheel Drive
Models
• Recreational towing with all fourwheels on the ground is allowed
ONLY if the rear driveshaft is
removed. See your authorized dealer
or refer to the Service Manual. Towing
with the rear wheels on the ground
while the driveshaft is connected can
result in severe transmission damage. • The parking brake must be firmly
engaged and the wheels chocked
during driveshaft removal and
installation. The parking brake must
remain engaged unless the vehicle is
securely and properly connected to
the tow vehicle, or the driveshaft is
completely reinstalled. See your
authorized dealer for proper driveshaft
removal and reinstallation procedures,
including flange orientation/alignment,
use of thread-locking compound,
proper bolt torque specifications, etc.
Towing - Four-Wheel Drive
Models
NOTE: The transfer case must be shifted
into N (Neutral), automatic transmission
must be shifted into PARK,and manual
transmission must be placed in gear (NOT
in NEUTRAL) for recreational towing.
• Bring the vehicle to a complete stop,turn off the engine and press and hold
the brake pedal.
• Shift the automatic transmission into NEUTRAL or depress the clutch
pedal on a manual transmission.
• Shift the transfer case lever into N (Neutral).
• Start the engine and shift the transmission into REVERSE.
• Release the brake pedal (and clutch pedal on manual transmissions) for
five seconds and ensure that there is
no vehicle movement.
• Repeat the previous step with automatic transmission in DRIVE or
manual transmission in first gear.
• Turn OFF the engine and leave the ignition switch in the unlocked OFF
position.
• Firmly apply the parking brake and shift the transmission into PARK or
place manual transmission in gear
(NOT in Neutral).

• Attach the vehicle to the tow vehicleusing a suitable tow bar and release
the parking brake.
• Disconnect the negative battery cable, and secure it away from the
negative battery post.
• Refer to your Owner's Manual on the DVD for further details.
CAUTION!
• Front or rear wheel lifts should notbe used. Internal damage to the
transmission or transfer case will
occur if a front or rear wheel lift is
used when recreational towing.
• Tow only in the forward direction. Towing this vehicle backwards can
cause severe damage to the
transfer case.
• Automatic transmissions must be placed in the PARK position for
recreational towing.
• Manual transmissions must be placed in gear (not in Neutral) for
recreational towing.
• Before recreational towing, perform the procedure outlined under
“Shifting Into NEUTRAL” to be
certain that the transfer case is
fully in NEUTRAL. Otherwise,
internal damage will result.
(Continued)
CAUTION!(Continued)
• Towing this vehicle in violation ofthe above requirements can cause
severe transmission and/or transfer
case damage. Damage from
improper towing is not covered
under the New Vehicle Limited
Warranty.
• Do not use a bumper-mounted clamp-on tow bar on your vehicle.
The bumper face bar will be
damaged.
• It is necessary to follow these steps to be certain that the transfer
case is fully in N (Neutral) before
recreational towing to prevent
damage to internal parts.
WARNING!
• You or others could be injured ifyou leave the vehicle unattended
with the transfer case in the N
(Neutral) position without first fully
engaging the parking brake. The
transfer case N (Neutral) position
disengages both the front and rear
driveshafts from the powertrain
and will allow the vehicle to move,
even if the transmission is in PARK.
The parking brake should always
be applied when the driver is not in
the vehicle.

JUMP-STARTING
• If your vehicle has a discharged battery it can be jump-started using a set of jumpercables 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.

• The battery in your vehicle is located in the right rear of the engine compartment.
• Set the parking brake, shift the automatic transmission into PARK and turn 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 (+) post of thedischarged vehicle.
• 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.
