Driving and Operating
.
Wait until the vehicle is out of the curve
before accelerating gently into the
straightaway.
Steering in Emergencies
.
There are some situations when steering
around a problem may be more effective
than braking.
.
Holding both sides of the steering wheel
allows you to turn 180 degrees without
removing a hand.
.
Antilock Brake System (ABS) allows
steering while braking.
Off-Road Recovery
The vehicle's right wheels can drop off the
edge of a road onto the shoulder while
driving. Follow these tips:
1. Ease off the accelerator and then,
if there is nothing in the way, steer the
vehicle so that it straddles the edge of
the pavement.
2. Turn the steering wheel about
one-eighth of a turn, until the right front
tire contacts the pavement edge.
3. Turn the steering wheel to go straight
down the roadway.
Loss of Control
Skidding
There are three types of skids that
correspond to the vehicle's three control
systems:
.
Braking Skid
—
wheels are not rolling.
.
Steering or Cornering Skid
—
too much
speed or steering in a curve causes tires
to slip and lose cornering force.
.
Acceleration Skid
—
too much throttle
causes the driving wheels to spin.
Defensive drivers avoid most skids by taking
reasonable care suited to existing conditions,
and by not overdriving those conditions. But
skids are always possible.
If the vehicle starts to slide, follow these
suggestions:
.
Ease your foot off the accelerator pedal
and steer the way you want the vehicle
to go. The vehicle may straighten out. Be
ready for a second skid if it occurs.
.
Slow down and adjust your driving
according to weather conditions. Stopping
distance can be longer and vehicle control
can be affected when traction is reduced
by water, snow, ice, gravel, or other
material on the road. 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.
.
Try 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.
Remember: Antilock brakes help avoid only
the braking skid.
