Fault
{
Warning
If there is a fault in the ABS, the
wheels may be liable to lock due
to braking that is heavier than
normal. The advantages of ABS
are no longer available. During
hard braking, the vehicle can no
longer be steered and may
swerve.
Have the cause of the fault rectified
by a Chevrolet dealers.
Parking Brake
Always apply parking brake firmly
without pressing the release button
and apply as firmly as possible on a
downhill or uphill slope.
To release the parking brake, pull
the lever up slightly, press the
release button and fully lower the
lever.
To reduce the operating forces of
the parking brake, press the foot
brake at the same time.
See Brake and Clutch System
Warning Light 0 90.
Brake Assist
Brake Assist detects rapid brake
pedal applies due to emergency
braking situations and provides
additional braking to activate the
Antilock Brake System (ABS) if the
brake pedal is not pushed hard
enough to activate ABS normally.
Minor noise, brake pedal pulsation,
and/or pedal movement during this
time may occur. Continue to apply
the brake pedal as the driving
situation dictates. Brake Assist
disengages when the brake pedal is
released.
Hill Start Assist (HSA)
In vehicles equipped with Electronic
Stability Control (ESC) system the
Hill Start Assist (HSA) feature is
available. HSA may be useful when
the vehicle is stopped on a grade.
This feature is designed to prevent
the vehicle from rolling, either
forward or rearward, during vehicle
drive off. After you completely stop
and hold the vehicle in a complete
standstill on a grade, HSA will
automatically activate. During the
transition period between when you
release the brake pedal and start to
accelerate to drive off on a grade,
HSA holds the braking pressure for
a maximum of 2 (two) seconds to
ensure that there is no rolling. The
brakes will automatically release
when the accelerator pedal is
applied within the 2 (two) second
window. The HSA system will not
activate if the vehicle is in a drive
gear and facing downhill or if the
vehicle is facing uphill and in
R (Reverse). There may be
situations on minor hills (less than
5% grade) with a loaded vehicle or
while pulling a trailer where HSA will
not activate. If you release the brake
pedal and then reapply the brake
pedal while HSA is activated, the
brake pedal typically feels firmer
with less pedal travel.
