nctions of ABS (Anti-lock Braking Sy stem) Obser
vethe impor tant sa fety guidelines forthe
driving saf ety sy stem. ABS cont
rols the brake pressure in critical situa‐
tions:
R The wheels are pr evented from lo cking when
braking, e.g. during maximum full-s top brak‐
ing or when there is insuf ficient tire traction
R The steerability of theve hicle in term s of
ph ysical possibilities is ensured when braking
R ABS is active from speeds of appr ox. 3 mph
(5 km/h). On a slippery road sur face, ABS
inter venes even if you on lybrake gently.
Sy stem limits
If th ere is a malfunction and theye llow 0025 ABS
wa rning lamp lights up continuously in the instru‐
ment display af terst arting the engine, ABS may
be impaired or inoperative.
If ABS inter venes, you will feel a pulsing in the
brake pedal. The pulsating brake pedal may be an
indication of hazardous road conditions and func‐
tions as a reminder totake extra care while driv‐
ing.
If ABS in terv enes: keep the brake pedal firm ly
depressed until the braking situation has passed.
To car ryout maximum full-s top braking:
dep ress the brake pedal with full forc e. Fu
nction of BAS (Brake Assist Sy stem) &
WARNING Risk of an accident caused by
a malfunction in BAS (Brake Assi stSys‐
te m)
If BA S is malfunctioning, the braking dis tance
in an emergency braking situation is
increased. #
Depress the brake pedal with full force
in emer gency braking situations. ABS
pr eve nts the wheels from locking. BA
S suppo rts yo u with additional braking forc e in
an emer gency braking situation.
If yo u depress the brake pedal quickl y,BA S is
acti vated:
R BAS au tomatically boosts the braking forc e of
th e brakes
R BAS can sho rten the braking dis tance
R ABS pr events the wheels from locking
When youre lease the brake pedal, the brakes
function as usual again. BAS is deactivated. 14 6
