WARNING
ARNING Risk of an accident caused by a
malfunction in BAS(Brake Assist System)
If BAS is malfunctioning, the braking distance
in an emer gency braking situation is
increased. #
Dep ress the brake pedal with full forc e in
emer gency braking situations. ABS pre-
ve nts the wheels from locking. The Brake Assist System (BAS) supports
your
emer gency braking situation with additional brake
fo rc e.
If yo u depress the brake pedal quickl y,BAS is
activated:
R BAS automatically boosts the brake pressure.
R BAS can shor tenth e braking distance.
R ABS pr events the wheels from locking.
The brakes will function as usual once youre lease
