CHEVROLET Tahoe - Manual (Page 377)

{ CAUTION:
When you are driving off-road, bouncing
and quick changes in direction can easily
throw you out of position. This could
cause you to lose control and crash. So,
whether you are driving on or off the road,
you and your passengers should wear
safety belts.
Scanning the Terrain
Off-road driving can take you over many different
kinds of terrain. You need to be familiar with the
terrain and its many different features. Here are
some things to consider.
Surface Conditions: Off-roading can take you
over hard-packed dirt, gravel, rocks, grass, sand,
mud, snow, or ice. Each of these surfaces affects
the steering, acceleration, and braking of your
vehicle in different ways. Depending upon the kind
of surface you are on, you may experience slipping,
sliding, wheel spinning, delayed acceleration, poor
traction, and longer braking distances.
Surface Obstacles: Unseen or hidden obstacles
can be hazardous. A rock, log, hole, rut, or
bump can startle you if you are not prepared for
them. Often these obstacles are hidden by
grass, bushes, snow, or even the rise and fall of
the terrain itself. Here are some things to consider:
• Is the path ahead clear?
• Will the surface texture change abruptly up
ahead?
• Does the travel take you uphill or downhill?
There is more discussion of these subjects
later.
• Will you have to stop suddenly or change
direction quickly?
When you drive over obstacles or rough terrain,
keep a firm grip on the steering wheel. Ruts,
troughs, or other surface features can jerk
the wheel out of your hands if you are not
prepared.
When you drive over bumps, rocks, or other
obstacles, the wheels can leave the ground. If this
happens, even with one or two wheels, you
cannot control the vehicle as well or at all.
