Scanning The Terrain - GMC Sierra Denali Classic 2007 Owner's Manual

Getting Familiar with Off-Road Driving
It is a good idea to practice in an area that is
safe and close to home before you go into the
wilderness. Off-road driving does require some new
and different driving skills. Here is what we mean.
Tune your senses to different kinds of signals.
Your eyes, for example, need to constantly sweep
the terrain for unexpected obstacles. Your ears
need to listen for unusual tire or engine sounds.
With your arms, hands, feet, and body, you will
need to respond to vibrations and vehicle bounce.
Controlling your vehicle is the key to successful
off-road driving. One of the best ways to control
your vehicle is to control your speed. Here are
some things to keep in mind. At higher speeds:
•
You approach things faster and you have less
time to scan the terrain for obstacles.
•
You have less time to react.
•
You have more vehicle bounce when you drive
over obstacles.
•
You will need more distance for braking,
especially since you are on an unpaved
surface.

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.
