Using ABS
Do not pump the brakes. Just hold the brake pedal
down firmly and let antilock work. A slight brake pedal
pulsation might be felt or some noise noticed, but this is
normal.
Braking in Emergencies
At some time, nearly every driver gets into a situation
that requires hard braking.
If the vehicle has Electronic Stability Control (ESC) with
Antilock Brake System (ABS), it allows the driver to steer
and brake at the same time. However, if the vehicle does
not have ESC with ABS, the first reaction — to hit the
brake pedal hard and hold it down — might be the wrong
thing to do. The wheels can stop rolling. Once they do,
the vehicle cannot respond to the driver’s 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 the driver was trying to
avoid, or into traffic.
If the vehicle does not have ABS, use a “squeeze”
braking technique. This gives maximum braking while
maintaining steering control. 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 helps
retain steering control. Without ABS, it is different.
See Antilock Brake System (ABS) on page 4-5.
In many emergencies, steering can help more than
even the very best braking.
Brake Assist
If this vehicle has ESC with ABS, it also has a Brake
Assist feature designed to assist the driver in stopping
or decreasing vehicle speed in emergency driving
conditions. This feature uses the stability system
hydraulic brake control module to supplement the
power brake system under conditions where the driver
has quickly and forcefully applied the brake pedal in
an attempt to quickly stop or slow down the vehicle.
The stability system hydraulic brake control module
increases brake pressure at each corner of the vehicle
until the ABS activates. Minor brake pedal pulsations
or pedal movement during this time is normal and the
driver should continue to apply the brake pedal as the
driving situation dictates The Brake Assist feature will
automatically disengage when the brake pedal is
released or brake pedal pressure is quickly decreased.
