BAS (Brake Assist System)
The BAS is designed to optimize the vehicle’s braking
capability during emergency braking maneuvers. The
system detects an emergency braking situation by sens-
ing the rate and amount of brake application and then
applies optimum pressure to the brakes. The system
applies optimum pressure to the brakes in emergency
braking conditions. This can help reduce braking dis-
tances. The BAS complements the antilock brake system
(ABS). Applying the brakes very quickly results in the
best BAS assistance. To receive the benefit of the system,
you must apply continuous braking pressure during the
stopping sequence. Do not reduce brake pedal pressure
unless braking is no longer desired.
Once the brake pedal is released, the BAS is deactivated.
