Shifting Out Of 4X4 LOW
With the vehicle at speeds of 0 to 3 mph (0
to 5 km/h), the ignition in the ON mode and
the engine running, shift the transmission
into NEUTRAL, and push the “4WD LOW”
button once. The “4WD LOW” indicator light
in the instrument cluster will flash and go
out when the shift is complete.
NOTE:
If shift conditions/interlocks are not met, a
message will flash from the instrument
cluster display with instructions on how to
complete the requested shift. Refer to
“Instrument Cluster Display” in “Getting
To Know Your Instrument Panel” for
further information.
Shifting into or out of 4WD LOW is
possible with the vehicle completely
stopped; however, difficulty may occur
due to the mating clutch teeth not being
properly aligned. Several attempts may be
required for clutch teeth alignment and
shift completion to occur. The preferred
method is with the vehicle rolling 0 to3 mph (0 to 5 km/h). If the vehicle is
moving faster than 3 mph (5 km/h), the
4WD system will not allow the shift.
NEUTRAL Shift Procedure
For the neutral shift procedure refer to
“Recreational Towing” in chapter for further
information.
Rear Electronic Locker (E-Locker) System
— If Equipped
The Rear E-Locker System features a
mechanical locking rear differential to
provide better traction in the 4WD LOW posi
-
tion. The “REAR LOCK” button is on the
Selec-Terrain Knob.
Activating The Rear E-Locker
To activate the Rear E-Locker System, the
following conditions must be met:
1. The 4WD system must be in 4WD LOW.
2. The ignition in the ON mode and the engine running.
3. Vehicle speed must be below 15 mph (24 km/h).
4. To engage Rear E-Locker, push the REAR LOCK button once. NOTE:

NOTE:
It may also be necessary to drive slowly
steering back and forth to complete
engagement and disengagement of the
E-Locker.

When disengaging Rear E-Locker, the indi-
cator lights in the instrument cluster and on
the REAR LOCK button will begin to flash.
When the shift is complete the REAR LOCK
indicator lights will remain off.

Shifting into or out of Rear E-Locker is
possible with the vehicle completely
stopped; however, difficulty may occur
due to the mating clutch teeth not being
properly aligned. Several attempts may be
required for clutch teeth alignment and
shift completion to occur. The preferred
method is for the vehicle to be rolling,
below 15 mph (24 km/h), while including
right and left steering maneuvers to allow
for the clutch teeth to align.
The Rear E-Locker System must be disen -
gaged prior to taking the vehicle out of
4WD LOW range. If 4WD LOW shift condi -
tions/interlocks are not met, a message
will flash from the instrument cluster
display with instructions on how to
complete the requested shift.
SELEC-TERRAIN
Description
Selec-Terrain allows the driver to specify the
driving surface to allow the vehicle systems
to provide the best performance possible
across a wide range of conditions
Rotate the Selec-Terrain knob to select the
desired mode.
Selec-Terrain Switch
Selec-Terrain offers the following modes:
AUTO — Fully automatic, full time
four-wheel drive operation can be used
both on and off road. Balances traction
with seamless steering feel to provide
improved handling and acceleration.
SNOW — Tuning set for additional stability
in inclement weather. Use when driving on
loose traction surfaces such as snow,
while either on or off road. When in SNOW
mode (depending on certain operating
conditions), the transmission may use
SECOND gear (rather than FIRST gear)
during launches, to minimize wheel slip -
page.
SPORT — This mode alters the transmis -
sion's automatic shift schedule for sportier
driving. Upshift speeds are increased to
make full use of available engine power.
NOTE:
SPORT mode is not available when 4WD
LOW is selected.
SAND/MUD — Off-road calibration for use
on low traction surfaces such as mud,
sand, or wet grass. The 4WD system
provides maximum capability to all
wheels. Some binding may be felt on high
traction surfaces. The electronic brake
system will be adjusted to reduce the
automatic braking of slipping wheels and
to allow the engine to operate without
restriction.

ROCK — Off-road calibration is only avail -
able in 4WD LOW range. ROCK mode
provides the most aggressive 4WD perfor -
mance for extreme off road terrain. Use for
low speed obstacles such as large rocks,
deep ruts, etc.
NOTE:
ROCK mode is only available on the vehi -
cles equipped with the Off-Road package.
Activate the Hill Descent Control or Selec
Speed Control for steep downhill control.
Refer to “Electronic Brake Control System”
