NOTE:
²Steps 1 and 2 in the ªPreferred Procedureº and the
ªAlternate Procedureº are requirements for shifting
the transfer case. If these requirements are not met
prior to attempting the shift or while the shift attempt
is in process, then the indicator light will flash, and the
current transfer case position will be maintained. To
retry a shift, move the 4WD Control Switch back to the
STARTING AND OPERATING 297

original position, make certain all shift requirements
have been met, wait five (5) seconds, and try the shift
again.
²The ignition switch must be in the ON 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
position, then the shift will not take place and no
position indicator lights will be on or flashing.
MP3022 Selec-Trac IITTransfer Case Ð If
Equipped
Operating Information & Precautions
The Selec-Trac IItactive on-demand transfer case pro-
vides four positions:
²2 (rear) wheel drive high range.
²4-wheel drive auto high range.
²Neutral.
²4-wheel drive low range.
This transfer case is intended to be driven in either the
2-wheel drive position (2WD) or the 4-wheel drive Auto
position (4WD Auto) for normal street and highway
conditions such as dry hard surfaced roads.
For added capability when traversing steep grades,
rough terrain, or extremely poor traction surfaces, select
the transfer case 4WD Low position. This position locks
the front driveshaft and rear driveshaft together and
forces the front and rear wheels to rotate at the same
speed while multiplying engine torque.
Use the transfer case Neutral (N) position for recreational
towing only. Refer to ªRecreational Towingº in this
section for specific procedures on shifting into and out of
Neutral (N).
298 STARTING AND OPERATING

CAUTION!
²The 4WD Low position is intended for loose or
slippery road surfaces only. Driving in this posi-
tion on dry hard surfaced roads may cause in-
creased tire wear and damage to the driveline
components.
²When operating your vehicle in 4WD LOW, the
engine speed is approximately three times that of
the 2WD position or 4WD AUTO position at a
given road speed. Take care not to over-speed the
engine and do not exceed 25 mph (40 km/h).
²Proper operation of 4-wheel drive vehicles de-
pends on tires of equal size, type, and circumfer-
ence on each wheel. Any difference in tire size can
cause damage to the transfer case.
WARNING!
²You or others could be injured if you leave the
vehicle unattended with the transfer case in the
Neutral (N) position without first fully engaging
the parking brake. The transfer case Neutral (N)
position disengages both the front driveshaft and
rear driveshaft from the powertrain and it will
allow the vehicle to move despite the transmission
position. The parking brake should always be
applied when the driver is not in the vehicle.
²Always engage the parking brake when powering
down the vehicle if the ªSERV 4WDº light is
illuminated. Not engaging the parking brake may
allow the vehicle to roll, which may cause personal
injury.
²Since 4-wheel drive provides improved traction,
there is a tendency to exceed safe turning and
stopping speeds. Do not go faster than road con-
ditions permit. You or others could be injured.

Shift Positions
The electronic transfer case switch is located on the center
console next to the gear selector lever.
2WD
Rear Wheel Drive High Range - Normal street and
highway driving. Dry hard surfaced roads.4WD Auto
4-Wheel-Drive Auto High Range ± This active on-
demand position makes available optimum traction for a
wide range of conditions, while maximizing driver con-
venience. This position is always in 4-wheel drive mode,
with a normal 42% front axle, 58% rear axle torque split.
The system also anticipates and prevents slip by redirect-
ing torque as necessary, up to 100% to the front or rear
axle, if needed.
4WD Low
4-Wheel-Drive Low Range - Low speed 4-wheel drive
that locks the front driveshaft and rear driveshaft to-
gether and forces the front and rear wheels to rotate at the
same speed. Additional traction and maximum pulling
power for loose or slippery road surfaces only. Do not
exceed 25 mph (40 km/h). This position allows engine
starting without depressing the clutch pedal on vehicles
equipped with a manual transmission. Refer to ªClutch

Transfer Case Position Indicator Lights
The 4WD indicator lights are located in the instrument
cluster. The ªNº (Neutral) indicator light is located on the
4WD Control Switch. If there is no indicator light on or
flashing, the transfer case position is 2-wheel drive
(2WD). If the indicator light is on, the desired position
(4WD AUTO, 4WD LOW, or NEUTRAL) has been ob-
tained.If One or More Shift Requirements are not met:
²An indicator light will flash.
²The transfer casewill notshift.
NOTE:The ªSERV 4WDº warning light monitors the
electric shift 4WD system. If this light remains on after
engine start up, or it illuminates during driving, it means
that the 4WD system is not functioning properly and that
service is required.
Shifting Procedures
NOTE:If any of the requirements to select a new
transfer case position have not been met, the transfer case
will not shift, the indicator light for the previous position
will remain ON, and the newly selected position indica-
tor light will continue to flash until all the requirements
for the selected position have been met. To retry a shift,
move the 4WD Control Switch back to the original

position, make certain all shift requirements have been
met, wait five (5) seconds, and try the shift again.
2WD to 4WD Auto
Move the 4WD Control Switch to the desired position.
Shifts between 2WD and 4WD Auto can be done with the
vehicle stopped or in motion. If the vehicle is stopped,
the ignition switch must be in the ON position with the
engine either OFF or RUNNING. This shift cannot be
completed if the ignition switch is in the ACC position.
2WD or 4WD Auto to 4WD Low
When shifting into or out of 4WD LOW, some gear noise
may be heard. This noise is normal and is not detrimental
to the vehicle or its occupants.
Shifting can be performed with the vehicle rolling 2-3
mph (3-5 km/h) using the ªPreferred Procedureº or
completely stopped using the ªAlternate Procedures.ºPreferred Procedure
1. With the engine RUNNING, slow the vehicle speed to
2-3 mph (3-5 km/h).
2. Shift the transmission into ªNº (Neutral) (automatic
transmission), or depress the clutch pedal (manual trans-
mission).
3. While still rolling, move the 4WD Control Switch to
the desired position.
4. After the desired position indicator light is ON (not
flashing), shift the transmission into gear (automatic
transmission), or release the clutch pedal (manual trans-
mission).
Alternate Procedure
1. Bring the vehicle to a complete stop.

ON-ROAD DRIVING TIPS
Utility vehicles have higher ground clearance and a
narrower track to make them capable of performing in a
wide variety of off-road applications. Specific design
characteristics give them a higher center of gravity than
ordinary cars.
An advantage of the higher ground clearance is a better
view of the road, allowing you to anticipate problems.
They are not designed for cornering at the same speeds as

caution and maintain a steady controlled speed less than
5 mph (8 km/h) in deep water to minimize wave effects.
Flowing Water
If the water is swift flowing and rising (as in storm
run-off) avoid crossing until the water level recedes
and/or the flow rate is reduced. If you must cross
flowing-water, avoid depths in excess of 9 inches. The
flowing water can erode the streambed causing your
vehicle to sink into deeper water. Determine exit point(s)
that are downstream of your entry point to allow for
drifting.
Standing Water
Avoid driving in standing water deeper than 20 inches,
and reduce speed appropriately to minimize wave ef-
fects. Maximum speed in 20 inches of water is less than 5
mph (8 km/h).Maintenance
After driving through deep water, inspect your vehicle
fluids and lubricants (engine, transmission, axle, transfer
case) to assure they have not been contaminated. Con-
taminated fluids and lubricants (milky, foamy in appear-
ance) should be flushed/changed as soon as possible to
prevent component damage.
Driving In Snow, Mud and Sand
In heavy snow, when pulling a load, or for additional
control at slower speeds, shift the transmission to a low
gear and shift the transfer case to 4WD Low if necessary.
Refer to ªFour-Wheel Drive Operationº in this section.
Do not shift to a lower gear than necessary to maintain
headway. Over-revving the engine can spin the wheels
and traction will be lost.
Avoid abrupt downshifts on icy or slippery roads, be-
cause engine braking may cause skidding and loss of
control.
