Scanning the Terrain
Off-road driving can take you over
many different kinds of terrain. Be
familiar with the terrain and its many
different features.
Surface Conditions:Off-roading
surfaces can be hard-packed dirt,
gravel, rocks, grass, sand, mud,
snow, or ice. Each of these surfaces
affects the vehicle's steering,
acceleration, and braking in different
ways. Depending on the surface,
slipping, sliding, wheel spinning,
delayed acceleration, poor traction,
and longer braking distances can
occur. Surface Obstacles:
Unseen or
hidden obstacles can be hazardous.
A rock, log, hole, rut, or bump can
startle you if you are not prepared
for them. Often these obstacles are
hidden by grass, bushes, snow,
or even the rise and fall of the
terrain itself.
Some things to consider:
.Is the path ahead clear?
.Will the surface texture change
abruptly up ahead?
.Does the travel take you uphill or
downhill?
.Will you have to stop suddenly
or change direction quickly?
When driving over obstacles or
rough terrain, keep a firm grip on
the steering wheel. Ruts, troughs,
or other surface features can jerk
the wheel out of your hands. When driving over bumps, rocks,
or other obstacles, the wheels can
leave the ground. If this happens,
even with one or two wheels, you
cannot control the vehicle as well or
at all.
Because you will be on an unpaved
surface, it is especially important to
avoid sudden acceleration, sudden
turns, or sudden braking.
Off-roading requires a different kind
of alertness from driving on paved
roads and highways. There are no
road signs, posted speed limits,
or signal lights. Use good judgment
about what is safe and what is not.

9-34 Driving and Operating
Ignition Positions
The ignition switch has four different
positions.
To shift out of P (Park), turn the
ignition to ON/RUN and apply the
regular brake pedal.
Notice:Using a tool to force the
key to turn in the ignition could
cause damage to the switch or
break the key. Use the correct
key, make sure it is all the way in,
and turn it only with your hand.
If the key cannot be turned by
hand, see your dealer. (A) LOCK/OFF:
This position
locks the ignition. It also locks
the transmission on automatic
transmission vehicles. It locks
the steering wheel on manual
transmission vehicles. The key can
only be removed in LOCK/OFF.
On vehicles with an automatic
transmission, the shift lever must be
in P (Park) to turn the ignition switch
to LOCK/OFF.
The steering can bind with the
wheels turned off center. If this
happens, move the steering wheel
from right to left while turning the
key to ACC/ACCESSORY. If this
doesn't work, then the vehicle needs
service.
(B) ACC/ACCESSORY: This is the
position in which you can operate
the electrical accessories or items
plugged into the accessory power
outlets. On automatic transmission
vehicles, this position unlocks the
ignition. On manual transmission
vehicles, it unlocks the ignition and steering wheel. Use this position
if the vehicle must be pushed or
towed.
(C) ON/RUN:
This position can
be used to operate the electrical
accessories and to display some
instrument panel cluster warning
and indicator lights. The switch
stays in this position when the
engine is running. The transmission
is also unlocked in this position on
automatic transmission vehicles.
If you leave the key in the
ACC/ACCESSORY or ON/RUN
position with the engine off, the
battery could be drained. You may
not be able to start the vehicle if the
battery is allowed to drain for an
extended period of time.
(D) START: This is the position that
starts the engine. When the engine
starts, release the key. The ignition
switch returns to ON/RUN for
driving.

Driving and Operating 9-47
Notice:Operating the vehicle
in Four-Wheel-Low Lock above
48 km/h (30 mph) for any
extended period of time could
cause damage to the transfer
case. Do not operate the vehicle
in Four-Wheel-Low Lock above
48 km/h (30 mph) for extended
periods.
4
n Q(Four-Wheel-Low Lock):
This setting delivers extra torque
to all four wheels and is used for
extreme off-road conditions.
If the vehicle has locking axles,
they can be locked for additional
traction in extreme off-road
situations. See Locking Rear Axle
on page 9‑54andLocking Front
Axle on page 9‑55.
Indicator lights in the buttons show
which setting the transfer case is
in. The indicator lights will come
on briefly when the ignition is in
ON/RUN. The If the lights do not
come on, take the vehicle to your
dealer for service. An indicator light will flash while shifting the transfer
case. If the transfer case cannot
make a requested shift, it will return
to the last chosen setting.
If the SERV 4WD message on the
Driver Information Center (DIC)
stays on, take the vehicle to your
dealer for service. See Service 4WD
message under
Driver Information
Center (DIC) on page 5‑18.
Shifting between Four-Wheel High
and Four-Wheel-High Lock
With the vehicle traveling less than
120 km/h (75 mph), press and
release the Four-Wheel High or
Four-Wheel-High Lock button.
It may be necessary to drive
backwards while turning for a
distance of 7.5 m (25 feet) to get
the lock feature to disengage.
Shifting into Four-Wheel Low Lock
Notice: Shifting the transmission
into gear before the indicator
light stops flashing could cause
damage to the transfer case. Always wait until the indicator
light stops flashing before putting
the transmission back in gear.
To shift into Four-Wheel-Low Lock,
the ignition must be in ON/RUN and
the vehicle must be stopped or
moving less than 5 km/h (3 mph)
with the transmission in N (Neutral).
The preferred method for shifting
into Four-Wheel Low is to have
the vehicle moving 1.6 to 3.2 km/h
(1 to 2 mph). Press and release
the Four-Wheel-Low Lock button.
If the vehicle has a manual
transmission, the clutch pedal must
be pressed to the floor while you
press the Four-Wheel-Low Lock
button, or the shift will not be
completed. You must wait for the
Four-Wheel-Low Lock indicator light
to stop flashing and remain lit before
shifting the transmission into gear.
It is normal for the vehicle to have
engagement noise and bump when
shifting between Four-Wheel Low
and Four-Wheel High ranges or
from Neutral.
