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 the 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: The Traction Control System (TCS) helps to
avoid only the acceleration skid. See Traction Control
System (TCS) on page 4-9. If the TCS system is off,
then an acceleration skid is best handled by easing your
foot off the accelerator pedal.
If the 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,
the vehicle may straighten out. Always be ready for
a second skid if it occurs.
The Electronic Stability Control (ESC) system might
activate. See Electronic Stability Control (ESC) on
page 4-6.
Of course, traction is reduced when water, snow, ice,
gravel, or other material is on the road. For safety, 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 might not realize the
surface is slippery until the 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.
Even though the vehicle has Electronic Stability
Control (ESC) with Antilock Brake System (ABS),
remember: ABS helps avoid only the braking skid.
If the ABS is ever disabled, in a braking skid, where the
wheels are no longer rolling, release enough pressure
on the brakes to get the wheels rolling again. This
restores steering control. Push the brake pedal down
steadily when you have to stop suddenly. As long as the
wheels are rolling, you will have steering control.
