STARTING AND OPERATING 153
The ignition switch must be in the ON position
for a shift to take place and for the position indi-
cator lights to be operable. If the ignition switch
i
s not in the ON position, the shift will not take
place and no position indicator lights will be on
or flashing.
ELECTRONICALLY SHIFTED TRANSFER
C
ASE (6-SPEED TRANSMISSION)
I
F EQUIPPED
The electronic shift transfer case is operated by
the 4WD Control Switch (Transfer Case Switch),
which is located on the instrument panel.
Four-Position/On-Demand Transfer Case
This electronically shifted transfer case provides
four mode positions:
Two-Wheel Drive High Range (2WD)
Four-Wheel Drive High Range (4WD HIGH)
Four-Wheel Drive Low Range (4WD LOW)
N (NEUTRAL)
For additional information on the appropriate use
of
each transfer case mode position, see the
information below:
2WD
Two-Wheel Drive High Range — This range is for
n
ormal street and highway driving on dry, hard
surfaced roads.
4WD HIGH
Four-Wheel Drive High Range — This range
m
aximizes torque to the front driveshaft, forcing
the front and rear wheels to rotate at the same
speed. This range provides additional traction for
loose, slippery road surfaces only.
4WD LOW
Four-Wheel Drive Low Range This range provides
l
ow speed four-wheel drive. It maximizes torque to
the front driveshaft, forcing the front and rear
wheels to rotate at the same speed. This range
provides additional traction and maximum pulling
power for loose, slippery road surfaces only. Do not
exceed 25
mph (40 km/h).
N (Neutral)
Neutral This range disengages both the front and
r
e
ar driveshafts from the powertrain. To be used
for flat towing behind another vehicle
Ú page 222.
This electronically shifted transfer case is designed
to
be driven in the two-wheel drive position
(two-wheel drive) for normal street and highway
conditions on dry, hard surfaced roads.
When additional traction is required, the transfer
case 4WD High and 4WD Low positions can be
used to maximize torque to the front driveshaft,
forcing the front and rear wheels to rotate at the
same speed. This is accomplished by rotating the
four-wheel drive Control Switch to the desired
position.
For specific shifting instructions Ú page 154.
The 4WD High and 4WD Low positions are
d
e
signed for loose, slippery road surfaces only.
Driving in the 4WD High and 4WD Low positions on
dry hard surfaced roads may cause increased tire
wear and damage to the driveline components.
WARNING!
You or others could be injured or killed if you
leave the vehicle unattended with the transfer
case in the N (Neutral) position without first fully
engaging the parking brake. The transfer case N
(Neutral) position disengages both the front and
rear drive shafts from the powertrain and will
allow the vehicle to roll, even if the transmission
is in PARK. The parking brake should always be
applied when the driver is not in the vehicle.
