BAS
G Observe Safety notes, see
page 64.
The Brake Assist System (BAS) operates in
emergency situations. If you apply the brakes
very quickly, the BAS automatically provides
full brake boost, thereby potentially reducing
the braking distance.
X
Apply continuous full braking pressure until
the emergency braking situation is over.
The ABS will prevent the wheels from
locking.
When you release the brake pedal, the brakes
function again as normal. The BAS is then
deactivated.
G Warning!
If the BAS malfunctions, the brake system
still functions, but without the additional
brake boost available that the BAS would
normally provide in an emergency braking
maneuver. Therefore, the braking distance
may increase.

adhesive friction between the tires and the
road surface) and handling.

The ESP recognizes when a wheel is
spinning or if the vehicle starts to skid. By
applying brakes to individual wheels and by
