Overdrive Operation
The automatic transmission includes an elec-
tronically controlled Overdrive (fifth gear). The
transmission will automatically shift into Over-
drive if the following conditions are present:
•
the shift lever is in the DRIVE position,
•
vehicle speed is sufficiently high, and
•
the driver is not heavily pressing the
accelerator.

WARNING!
Failure to engage a position completely can
cause transfer case damage or loss of power
and vehicle control. You could have a colli-
sion. Do not drive the vehicle unless the
transfer case is fully engaged.
Operating Instructions/Precautions
The transfer case provides four mode positions:
•
2H (Two-wheel drive high range)
•
4H (Four-wheel drive high range)
•
N (Neutral)
•
4L (Four-wheel drive low range)
The transfer case is intended to be driven in the
2H position for normal street and highway con-
ditions such as hard-surfaced roads.
In the event that additional traction is required,
the transfer case 4H and 4L positions can be
used to lock the front and rear driveshafts
together, forcing the front and rear wheels to
rotate at the same speed. This is accomplished
by simply moving the shift lever to one of these
positions. The 4H and 4L positions are intended
for loose, slippery road surfaces only and not
intended for normal driving. Driving in the 4H
and 4L positions on hard-surfaced roads will
cause increased tire wear and damage to the
driveline components.
The “4WD Indicator Light” (located in the instru-
ment cluster) alerts the driver that the vehicle is
in four-wheel drive, and the front and rear
driveshafts are locked together. The light will
illuminate when the transfer case is shifted into
the 4H position.
NOTE:
Do not attempt to shift when only the front or
rear wheels are spinning. The transfer case
is not equipped with a synchronizer, and the
front and rear driveshaft speeds must be
equal for a shift to take place. Shifting while
only the front or rear wheels are spinning
can cause damage to the transfer case.
