Crossing Obstacles

-
Approach Angle a Key to Mobility. If you encounter
a large dip in the terrain, do not enter straight on; enter
at an angle (15 _ minimum approach (A), 75 _ maximum
approach angle (B)). For very large dips, ditches or
small washes, coast in, using the engine as a brake.
Then, use the low ranges in the transmission and transfer
case to power out.
4-26
Roll Your 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
components.
