FOUR-WHEEL DRIVE OPERATION — IF
EQUIPPED
Four-wheel drive trucks are equipped with
either a manually shifted transfer case or an
electronically shifted transfer case.
ELECTRONICALLY SHIFTED TRANSFER
C
ASE (EIGHT SPEED TRANSMISSION ) —
I
F EQUIPPED
This is an electronically shifted transfer case
and is operated by the 4WD Control Switch
(Transfer Case Switch), which is located on the
instrument panel.
Four-Position 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
normal street and highway driving on dry, hard
surfaced roads.
4WD High
Four-Wheel Drive High Range — This range
provides torque to the front driveshaft (engages
four-wheel drive) which allows front and rear
wheels to spin at the same speed. This provides
additional traction for loose, slippery road
surfaces only.
4WD Low
Four-Wheel Drive Low Range — This range
provides low speed four-wheel drive. It maximizes
torque (increased torque over 4WD High) to the
front driveshaft, allowing 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) in this range.
N (Neutral)
N (Neutral) — This range disengages both the
front and rear driveshafts from the powertrain.
To be used for flat towing behind another
vehicle Ú page 214.
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
shaft 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.
