Scanning The Terrain - Chevrolet 2008 TrailBlazer Owner's Manual

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.
Because you will be on an unpaved surface, it is
especially important to avoid sudden acceleration,
sudden turns, or sudden braking.
In a way, off-road driving requires a different kind of
alertness from driving on paved roads and highways.
There are no road signs, posted speed limits, or signal
lights. You have to use your own good judgment
about what is safe and what is not.
