Braking In Emergencies; Electronic Stability Control (Esc) - Chevrolet 2010 Impala Owner's Manual

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 might be
heard, but this is normal.

Braking in Emergencies

ABS allows the driver to steer and brake at the same
time. In many emergencies, steering can help more than
even the very best braking.

Electronic Stability Control (ESC)

Your vehicle may have an Electronic Stability Control
(ESC) system which combines antilock brake, traction
and stability control systems and helps the driver
maintain directional control of the vehicle in most driving
conditions.
When you first start your vehicle and begin to drive
away, the system performs several diagnostic checks to
ensure there are no problems. You may hear or feel
the system working. This is normal and does not mean
there is a problem with your vehicle. The system
should initialize before the vehicle reaches 20 mph
(32 km/h).
5-6
If the system fails to turn on or activate, the ESC/TCS
light will be on solid, and the SERVICE STABILITRAK
message will be displayed.
For more information, see Driver Information Center
(DIC) on page 4-37.
You may also feel or hear the system working; this is
normal.
When the light is on solid and the SERVICE
STABILITRAK message is displayed, the system will not
assist the driver in maintaining directional control of
the vehicle. Adjust your driving accordingly. See
DIC Warnings and Messages on page 4-44.
The Electronic Stability Control (ESC) system is
automatically enabled whenever you start your vehicle.
To assist the driver with vehicle directional control,
especially in slippery road conditions, you should always
leave the system on. But, you can turn ESC off if you ever
need to.
This light will flash on the
instrument panel cluster
when the ESC system
is both on and activated.
