Braking in Emergencies

At some time, nearly every driver gets into a situation
that requires hard braking.
If you have anti-lock, you can steer and brake at the
same time. However, if you do not have anti-lock, your
first reaction — to hit the brake pedal hard and hold
it down — may be the wrong thing to do. Your wheels
can stop rolling. Once they do, the vehicle can not
respond to your steering. Momentum will carry it
in whatever direction it was headed when the wheels
stopped rolling. That could be off the road, into the very
thing you were trying to avoid, or into traffic.
If you do not have anti-lock, use a "squeeze" braking
technique. This will give you maximum braking while
maintaining steering control. You can do this by pushing
on the brake pedal with steadily increasing pressure.
In an emergency, you will probably want to squeeze the
brakes hard without locking the wheels. If you hear or
feel the wheels sliding, ease off the brake pedal.
This will help you retain steering control. If you do have
anti-lock, it is different. See Anti-Lock Brake System
(ABS) on page 4-7
In many emergencies, steering can help you more than
even the very best braking.

Enhanced Traction System (ETS)

If the vehicle has an Enhanced Traction System (ETS)
it will limit wheel spin. This is especially useful in
slippery road conditions. The system operates only if
it senses that one or both of the front wheels are
spinning or beginning to lose traction. When this
happens, the system reduces engine power and may
also upshift the transaxle to limit wheel spin.
You may feel or hear the system working, but this
is normal.
If the vehicle is in cruise control when the enhanced
traction system begins to limit wheel spin, the cruise
control will automatically disengage. The cruise control
can be used again when road conditions allow safe
use of it. See "Cruise Control" under Turn
Signal/Multifunction Lever on page 3-7.
This light will come on the
instrument panel cluster
while the ETS is limiting
wheel spin. See Enhanced
Traction System Warning
Light on page 3-34.
