CROSSING OBSTACLES

Approach Angle
If you encounter a large dip in the
terrain, do not enter straight on.
Enter with an approach angle
between 15° and 75°
For very large dips, ditches or small
washes, coast in (with the trans-
mission and transfer case in the
lowest gears) using the engine as a
brake. Then, use the low ranges in
the transmission and transfer case
to power out.

A
Large Rocks
Roll the tires over large rocks. Do
not straddle large rocks. Drive over
them, letting the tire envelop the
rock. The tread of the tire is thicker
and tougher than the sidewall of
.
the tire and is more resilient to
impact than underbody compo-
nents.
A
Log Crossing
Using the proper technique, the
vehicle will cross logs up to 25.4
cm (10 inches) in diameter.
Approach the log at approximate-
ly a 15° angle with the transmis-
sion in first gear and the transfer
case in Four-Wheel Low Lock, and
"walk" the vehicle over, one tire at
a time.
It may be necessary to alternate
between your brake pedal and
accelerator to avoid spin-out. Ease
the vehicle down from the log
using your brake.
