2. Shift the transmission into PARK.
3. Turn the ignition switch to the OFF position.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is nolonger detected, the transmission will return to normal
operation.
NOTE: Even if the transmission can be reset, we recom-
mend that you visit your authorized dealer at your
earliest possible convenience. Your authorized dealer has
diagnostic equipment to determine if the problem could
recur.
If the transmission cannot be reset, authorized dealer
service is required.Electronic Range Select (ERS) Operation —
Six-Speed Transmission (1500 Models Only)
The Electronic Range Select (ERS) shift control allows the
driver to limit the highest available gear when the
transmission is in DRIVE. For example, if you set the
transmission gear limit to 4 (fourth gear), the transmis-
sion will not shift above fourth gear, but will shift
through the lower gears normally.
Use of ERS (or TOW/HAUL mode) also enables an
additional underdrive gear which is not normally used
during through-gear accelerations. This additional gear
can improve vehicle performance and cooling capability
when towing a trailer on certain grades. In ERS mode,
gears 1 though 3 are underdrive gears, and ERS 4 is direct
drive. ERS 5 and 6 (Overdrive gears) are the same as the
normal fourth and fifth gears.

WARNING!(Continued)
•Unintended movement of a vehicle could injure
those in or near the vehicle. As with all vehicles,
you should never exit a vehicle while the engine is
running. When the ignition is in the LOCK/OFF
(key removal) position, the transmission is locked
in PARK, securing the vehicle against unwanted
movement.
• Before exiting a vehicle, always apply the parking
brake, shift the automatic transmission into PARK,
turn the vehicle OFF, remove the key fob from the
ignition and lock your vehicle. If equipped with
Keyless Enter-N-Go, always make sure the keyless
ignition node is in “OFF” mode, remove the Key
Fob from the vehicle and lock the vehicle.

WARNING! (Continued)
•When leaving the vehicle, always make sure the
ignition is in the OFF position, remove the Key Fob
from the vehicle, and lock the vehicle.
• Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing children to
be in a vehicle unattended is dangerous for a
number of reasons. A child or others could be
seriously or fatally injured. Children should be
warned not to touch the parking brake, brake pedal
or the gear selector.
• Do not leave the Key Fob in or near the vehicle (or
in a location accessible to children), and do not
leave the ignition (in a vehicle equipped with
Keyless Enter-N-Go) in the ACC or ON/RUN
mode. A child could operate power windows, other
controls, or move the vehicle.

selected. PARK, REVERSE, and NEUTRAL will continue
to operate. The Malfunction Indicator Light (MIL) may be
illuminated. Limp Home Mode allows the vehicle to be
driven to an authorized dealer for service without dam-
aging the transmission.
In the event of a momentary problem, the transmission
can be reset to regain all forward gears by performing the
following steps:
1. Stop the vehicle.
2. Shift the transmission into PARK.
3. Turn the ignition switch to the OFF position.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is nolonger detected, the transmission will return to normal
operation. NOTE:
Even if the transmission can be reset, we recom-
mend that you visit your authorized dealer at your
earliest possible convenience. Your authorized dealer has

recur.
If the transmission cannot be reset, authorized dealer
service is required.

position, the rear axle is locked. In the FRONT/REAR
LOCK position, the front and rear axles are locked.
NOTE:Even when the axles are in the AXLE UNLOCK
position, the limited slip differential in the rear axle still
provides torque biasing capability for moderate low
traction environments.
During the command to lock the axle, the indicator light
will flash until the axle is locked. After the lock command
has been successfully executed, the light will remain on
solid.
To lock the rear axle, place the vehicle in 4LO. Refer to
“Four Wheel Drive Operation” in “Starting And Operat-
ing” for further information. Move the axle locker switch
position to REAR LOCK while traveling less than 3 mph
(5 km/h). The RR indicator light will remain on when the
rear axle is locked. NOTE:
Left to right wheel speed difference may be
necessary to allow the axle to fully lock. If the indicator
light is flashing after placing the switch in the REAR
LOCK or FRONT/REAR LOCK position, drive the ve-
hicle in a turn or on loose gravel to expedite the locking
action.
WARNING!
Do not use the locked axle position for normal
driving. A locked front axle is intended for off-road
driving only. Locking the front axle during on-road
driving will reduce the steering ability. This could
cause a collision and you may be seriously injured.
To lock the front axle; move the axle locker switch to
FRONT/REAR LOCK while traveling less than 3 mph
(5 km/h). The indicator light will be solid when the front
axle is locked.

WARNING!
Always wear your seat belt and firmly tie down
cargo. Unsecured cargo can become projectiles in an
off-road situation.
When To Use Low Range
When driving off-road, shift into 4LO (Low Range) for
additional traction or to improve handling and control on
slippery or difficult terrain. Due to the lower gearing, low
range will allow the engine to operate in a higher power
range. This will allow you to idle over obstacles and
down hills, with improved control and less effort. Also,
use 4LO (Low Range) in rain, ice, snow, mud, sand, to get
heavy loads rolling, improve traction, or whenever 4HI
(High Range) traction will not do the job.
Driving In Snow, Mud And Sand
There is a drastic reduction in traction when driving in
snow, mud or sand. The vehicle will be less responsive to
steering, acceleration and braking inputs. Therefore you
should accelerate slowly, leave greater stopping distances
and avoid abrupt vehicle maneuvers. You want to keep a
slow constant steady pace. The key is to maintain the
vehicle’s momentum.
•Snow – In heavy snow or for additional control and
traction at slower speeds, shift the transmission to a
low gear and shift the transfer case to 4LO (Low
Range) if necessary. Do not shift to a lower gear than
necessary to maintain headway. Over-revving the en-
gine can spin the wheels and traction will be lost. If
you start to slow to a stop, try turning your steering
wheel no more than a ¼ turn quickly back and forth,
while still applying throttle. This will allow the tires to
get a fresh biteand help maintain your momentum.

6. Secure to the anchor point. Once you have establishedyour anchor point, secure the tree-trunk protector or
choker-chain around the object.CAUTION!
Always be certain the anchor you select will with-
stand the load.

NOTE: How to choose an anchor point:A secure anchor
is critical to winching operations. An anchor must be
strong enough to hold while winching. Natural anchors
include trees, stumps and rocks. Hook the cable as low as
possible. If no natural anchors are available when recov-
ering another vehicle, your vehicle becomes the anchor
point. In this case, be sure to put the transmission in
NEUTRAL, apply the hand brake and block its wheels to
prevent your vehicle from moving. Ideally, you’ll want
an anchor point that will enable you to pull straight in the
direction the vehicle will move. This allows the wire rope
to wind tightly and evenly onto the spooling drum. An
anchor point as far away as possible will provide the
winch with its greatest pulling power.
7. Attach the Clevis/D-shackle and Tree Trunk Protector. Attach the shackle to the two ends of the strap or chain
and through the hook loop, being careful not to over
tighten (tighten and back-off 1/2 turn). 8. Lock the clutch. Lock the winch drum by rotating the
clutch lever on the winch to engage.
NOTE: Always ensure the clutch is fully engaged or
disengaged.

11. Check your anchor. Make sure all connections aresecured and free of debris before continuing with the
winching procedure.
12. Check wire rope. The wire rope should be neatly wound around the spooling drum. Improper wind-
ing can cause damage to the wire rope. In certain situations you may decide to throw a heavy
blanket or similar object over the wire rope. A heavy
blanket can absorb energy should the wire rope break.
Place it on the wire rope midway between the winch and
the anchor point. Do this before the wire rope is put
under tension. Do not approach or move the blanket once
