Skidding

In a skid, a driver can lose control of the vehicle.
Defensive drivers avoid most skids by taking reasonable
care suited to existing conditions, and by not overdriving
those conditions. But skids are always possible.

The three types of skids correspond to your vehicle’s
three control systems. In the braking skid, the wheels are
not rolling. In the steering or cornering skid, too much
speed or steering in a curve causes tires to slip and lose
cornering force. And in the acceleration skid, too much
throttle causes the driving wheels to spin.

Remember: Any traction control system helps avoid only
the acceleration skid. If your traction control system is
off, then an acceleration skid is best handled by
easing your foot off the accelerator pedal.

If your vehicle starts to slide, ease your foot off the
accelerator pedal and quickly steer the way you want the
vehicle to go. If you start steering quickly enough, your
vehicle may straighten out. Always be ready for a second
skid if it occurs.

Of course, traction is reduced when water, snow, ice,
gravel, or other material is on the road. For safety, you
will want to slow down and adjust your driving to these
conditions. It is important to slow down on slippery
surfaces because stopping distance will be longer and
vehicle control more limited.

While driving on a surface with reduced traction, try
your best to avoid sudden steering, acceleration, or
braking, including reducing vehicle speed by shifting to a
lower gear. Any sudden changes could cause the tires to
slide. You may not realize the surface is slippery until
your vehicle is skidding. Learn to recognize warning
clues — such as enough water, ice, or packed snow on
the road to make a mirrored surface — and slow down
when you have any doubt.

Remember: Any Antilock Brake System (ABS) helps
avoid only the braking skid.

Off-Road Driving

Vehicles with all-wheel drive can be used for off-road
driving. Vehicles without all-wheel drive should not
be driven off-road except on a level, solid surface.

Many of the vehicle design features that help make the
vehicle more responsive on paved roads during poor
weather conditions also help make it better suited for
off-road use than conventional passenger vehicles.
The vehicle does not have features usually thought to
be necessary for extended or severe off-road use such
as special underbody shielding and transfer case low
gear range.
