CAUTION:_ Do not shift from low to high or vice versa with-
out coming to a complete stop and waiting for
the engine to return to normal idle speed. Dam-
age to the engine or drive train may occur. _TURNING YOUR VEHICLE
The vehicle is easier to steer in two-wheel drive
(2WD) than four-wheel drive (4WD). Steering
takes the most effort in 4WD with the differential
locked (DIFF. LOCK).
It is possible for the vehicle to roll over or go out of
control if you attempt sharp, high-speed turns. You
should also be careful making sharp turns on
rough terrain. Do not attempt to turn around or
make abrupt maneuvers on slopes.

Position your hands on the steering wheel so that
your thumbs and fingers do not wrap around the
wheel. This is particularly important when driving
in rough terrain. The front wheels will move right
and left as they respond to the terrain, and this
movement will be felt in the steering wheel. A sud-
den jolt could wrench the steering wheel around,
and your thumbs or fingers could be injured if they
are in the way of the steering wheel spokes.
BRAKING
Braking ability is affected by the type of terrain. In
most cases, gradually application of the brakes is
more effective than abrupt braking, particularly on
loose surfaces like gravel. Always allow for greater
braking distance on rough, loose, or slippery sur-
faces.
