Transfer Case Position Indicator Lights
The Transfer Case Position Indicator Lights (4WD,
4LOW, and 4WD AUTO) are located in the instrument
cluster and indicate the current and desired transfer case
selection. When you select a different transfer case posi-
tion, the indicator lights will do the following:
If All Shift Conditions Are Met:
1. The current position indicator light will turn OFF.
2. The selected position indicator light will flash until thetransfer case completes the shift.
3. When the shift is complete, the indicator light for the selected position will stop flashing and remain ON. If One Or More Shift Conditions Are Not Met:
1. The indicator light for the current position will remain
ON.
2. The newly selected position indicator light will con- tinue to flash.
3. The transfer case will notshift.
NOTE: Before retrying a selection, make certain that all
the necessary requirements for selecting a new transfer
case position have been met. To retry the selection, turn
the control knob back to the current position, wait five
seconds, and retry selection. To find the shift require-
ments, refer to the Shifting Procedure for your transfer
case, located in this section.
The “SVC 4WD Warning Light” monitors the electronic
shift four-wheel drive system. If this light remains on
after engine start up or illuminates during driving, it
454 STARTING AND OPERATING

means that the four-wheel drive system is not function-
ing properly and that service is required.
WARNING!
Always engage the parking brake when powering
down the vehicle if the “SVC 4WD Warning Light” is
illuminated. Not engaging the parking brake may
allow the vehicle to roll which may cause personal
injury or death.
NOTE: Do not attempt to make a shift while only the
front or rear wheels are spinning. This could cause
damage to driveline components.
When operating your vehicle in 4WD LOW, the engine
speed is approximately three times that of the 2WD, 4WD
AUTO or 4WD LOCK positions at a given road speed.
Take care not to overspeed the engine and do not exceed
25 mph (40 km/h). Proper operation of four-wheel drive vehicles depends
on tires of equal size, type and circumference on each
wheel. Any difference in tire size can cause damage to the
drivetrain.
Because four-wheel drive provides improved traction,
there is a tendency to exceed safe turning and stopping
speeds. Do not go faster than road conditions permit.
WARNING!
You or others could be injured or killed if you leave
the vehicle unattended with the transfer case in the
NEUTRAL position without first fully engaging the
parking brake. The transfer case NEUTRAL position
disengages both the front and rear drive shafts from
the powertrain and will allow the vehicle to move
regardless of the transmission position. The parking
brake should always be applied when the driver is
not in the vehicle.

Shifting Procedure
NOTE:
•If any of the requirements to select a new transfer case
position have not been met, the transfer case will not
shift. The position indicator light for the previous
position will remain ON and the newly selected posi-
tion indicator light will continue to flash until all the
requirements for the selected position have been met.
• If all the requirements to select a new transfer case
position have been met, the current position indicator
light will turn OFF, the selected position indicator light
will flash until the transfer case completes the shift.
When the shift is complete, the position indicator light
for the selected position will stop flashing and remain
ON. 2WD To 4WD AUTO Or 4WD LOCK
Press the desired position on the 4WD Control Switch to
shift the transfer case. Shifts between 2WD and 4WD
AUTO and 4WD LOCK can be done with the vehicle
stopped or in motion. With the vehicle in motion, the
transfer case will engage/disengage faster if you momen-
tarily release the accelerator pedal after turning the
control switch. If the vehicle is stopped, the ignition
switch must be in the ON position with the engine either
running or OFF. This shift cannot be completed if the
ignition switch is in the ACC position.
2WD Or 4WD AUTO Or 4WD LOCK To 4WD LOW
NOTE:
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 occupants.
5
STARTING AND OPERATING 457

Shifting can be performed with the vehicle rolling 2 to
3 mph (3 to 5 km/h) or completely stopped. Use either of
the following procedures:
Preferred Procedure
1. With the engine running, slow the vehicle to 2 to3 mph (3 to 5 km/h).
2. Shift the transmission into NEUTRAL.
3. While still rolling, press the desired position on the transfer case control switch.
4. After the desired position indicator light is ON (not flashing), shift the transmission back into gear.
Alternate Procedure
1. Bring the vehicle to complete stop.
2. With the ignition switch in the ON position and the engine running, shift the transmission into NEUTRAL. 3. Press the desired position on the transfer case control
switch.
4. After the desired position indicator light is ON (not flashing), shift the transmission back into gear.
NOTE:
• If Steps 1 or 2 of either the Preferred or Alternate
Procedure are not satisfied prior to attempting the shift
or if they no longer are being met while the shift
attempt is in process, the desired position indicator
light will flash continuously while the original position
indicator light is ON, until all requirements have been
met.
• The 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.

Ramp Travel Index (RTI)
The ramp travel index is the distance, in inches, that you
can drive your vehicle with one wheel on a 20-degree
ramp without lifting any other wheel off the ground. This
distance up the ramp divided by the wheelbase of the
vehicle and multiplied by 1,000 is the RTI. This vehicle
has an RTI of 655, which means you can articulate one
front wheel 32 inches in the air while the other three
wheels remain in contact with the ground.
Water Fording Characteristics
Water fording characteristic is the vehicle’s ability to cross a
body of still water, where the powertrain and drivetrain are
safe from water ingestion. This vehicle has high water
fording characteristics with the ability to cross a pool of
water, without stopping, 24 inches deep at a maximum
speed of 10 mph (16 km/h) and a pool of water 30 inches
deep at a maximum speed of 5 mph (8 km/h), both with an
entrance ramp angle of 1.3 degrees.
CAUTION!
The door sill height is 25 inches. Water may intrude
into the interior of the vehicle at greater depths.
Simultaneous Brake And Throttle Operation
Many off-road driving conditions require the simultane-
ous use of the brake and throttle (two footed driving).
When climbing rocks, logs, or other stepped objects,
using light brake pressure with light throttle will keep the
vehicle from jerking or lurching. This technique is also
used when you need to stop and restart a vehicle on a
steep incline.
The Basics Of Off-Road Driving
You will encounter many types of terrain driving off-
road. You should be familiar with the terrain and area
before proceeding. There are many types of surface
conditions: hard packed dirt, gravel, rocks, grass, sand,
5
STARTING AND OPERATING 475

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 4L (Low Range)
if necessary. 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. 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
bite and help maintain your momentum.
CAUTION!
On icy or slippery roads, do not downshift at high
engine RPMs or vehicle speeds because engine brak-
ing may cause skidding and loss of control.
• Mud – Deep mud creates a great deal of suction
around the tires and is very difficult to get through.
You should use 4L (Low Range) with a gear low
enough to maintain your momentum without shifting.
If you start to slow to a stop, try turning your steering
wheel no more than a ¼ turn quickly back and forth
for additional traction. Mud holes pose an increased
threat of vehicle damage and getting stuck. They are
normally full of debris from previous vehicles getting
stuck. As a good practice before entering any mud
hole, get out and determine how deep it is, if there are
any hidden obstacles and if the vehicle can be safely
recovered if stuck.

STARTING AND OPERATING 477

•Sand – Soft sand is very difficult to travel through with
full tire pressure. When crossing soft sandy spots in a
trail maintain your vehicle’s momentum and do not
stop. The key to driving in soft sand using the appro-
priate tire pressure, accelerating slowly, avoiding
abrupt maneuvers and maintaining the vehicle’s mo-
mentum. If you are going to be driving on large soft
sandy areas or dunes, reduce your tire pressure to a
minimum of 15 psi (103 kPa) to allow for a greater tire
surface area. Reduced tire pressure will drastically
improve your traction and handling, while driving on
the soft sand, but you must return the tires to normal
air pressure before driving on pavement or other hard
surfaces. Be sure you have a way to air the tires back
up prior to reducing the pressure.CAUTION!
Reduced tire pressures may cause tire unseating and
total loss of air pressure. To reduce the risk of tire
unseating, while at a reduced tire pressure, reduce
your speed and avoid sharp turns or abrupt maneu-
vers.
Crossing Obstacles (Rocks And Other High
Points)
While driving off road, you will encounter many types of
terrain. These varying types of terrain bring different
types of obstacles. Before proceeding review the path
ahead to determine the correct approach and your ability
to safely recover the vehicle if something goes wrong.
Keeping a firm grip on the steering wheel, bring the
vehicle to a complete stop and then inch the vehicle
forward until it makes contact with the object. Apply the
478 STARTING AND OPERATING

WARNING!
Do not descend a steep grade in NEUTRAL. Use
vehicle brakes in conjunction with engine braking.
Descending a grade too fast could cause you to lose
control and be seriously injured or killed.
• Driving Across An Incline – If at all possible avoid
driving across an incline. If it is necessary, know your
vehicle’s abilities. Driving across an incline places
more weight on the down hill wheels, which increases
the possibilities of a down hill slide or rollover. Make
sure the surface has good traction with firm and stable
soils. If possible transverse the incline at an angle
heading slightly up or down.
WARNING!
Driving across an incline increases the risk of a
rollover , which may result in severe injury.
• If You Stall Or Begin To Lose Headway – If you stall
or begin to lose headway while climbing a steep hill,
allow your vehicle to come to a stop and immediately
apply the brake. Restart the engine and shift into
REVERSE. Back slowly down the hill allowing the
compression braking of the engine and transmission to
help regulate your speed. If the brakes are required to
control vehicle speed, apply them lightly and avoid
locking or skidding the tires.

STARTING AND OPERATING 483

WARNING!
If the engine stalls or you lose headway or cannot
make it to the top of a steep hill or grade, never
attempt to turn around. To do so may result in
tipping and rolling the vehicle, which may result in
severe injury. Always back carefully straight down a
hill in REVERSE. Never back down a hill in NEU-
TRAL using only the vehicle brakes. Never drive
diagonally across a hill, always drive straight up or
down.
Driving Through Water
Extreme care should be taken crossing any type of water.
Water crossings should be avoided if possible and only
be attempted when necessary, in a safe responsible
manner. You should only drive through areas which are
designated and approved. You should tread lightly andavoid damage to the environment. You should know
your vehicle’s abilities and be able to recover it if
something goes wrong. You should never stop or shut a
vehicle off when crossing deep water unless you ingested
water into the engine air intake. If the engine stalls do not
attempt to restart it. Determine if it has ingested water
first. The key to any crossing is low and slow. You want
to use first gear in 4L (Low Range) and proceed very
slowly with a constant slow speed (3-5 mph [5–8 km/h]
maximum) and light throttle. Keep the vehicle moving;
do not try to accelerate through the crossing. After
crossing any water higher than the bottom of the axle
differentials, you should inspect all of the vehicle fluids
for signs of water ingestion.
