Chevrolet Corvette Owner Manual - 2011
9-36 Driving and Operating
Brake Assist
This vehicle 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 pulsation 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.
Ride Control Systems
Traction Control
System (TCS)
The vehicle has a Traction Control
System (TCS) that limits wheel spin.
This is especially useful in slippery
road conditions. The system
operates only if it senses that the
rear wheels are spinning too much
or are beginning to lose traction.
When this happens, the system
works the rear brakes and reduces
engine power (by closing the throttle
and managing engine spark) to limit
wheel spin.
The TRACTION SYSTEM ACTIVE
message displays on the Driver
Information Center (DIC) when TCS
is limiting wheel spin. See Ride
Control System Messages on
page 5‑44. The system may be
heard or felt while it is working,
but this is normal.
If cruise control is being used when
TCS begins to limit wheel spin, the
cruise control will automatically
disengage. Cruise control may be
reengaged when road conditions
allow. See Cruise Control on
page 9‑44.
The SERVICE TRACTION SYSTEM
message and the TCS warning light
will come on if there is a problem
with TCS. See Ride Control System
Messages on page 5‑44.
When this light and the SERVICE
TRACTION SYSTEM message
are on, the system will not limit
wheel spin. Adjust your driving
accordingly.
