In wintry driving conditions, alwaysu
se
winter tyres (M+S tyres) and if necessary,
snow chains. Only in this way willt he driv-
ing safety systems describe dinthis section
work as effectively as possible. ABS (Anti-loc
kBraking System)
Important safety notes i
Observe the "Important safety notes" sec-
tio n(Ypage 61).
ABS regulate sbrake pressure in such away
tha tthe wheels do not lock when you brake.
This allowsy ou to continue steering the vehi-
cle when braking.
ABS works from aspeed of about 8km/h
upwards, regardless of road-surface condi-
tions. ABS works on slippery surfaces, even
when you only brake gently. G
WARNING
If ABS is faulty, the wheels could lock when
braking. This limits the steerability of the vehi-
cle when braking and the braking distance
may increase.
If ABS is deactivated due to amalfunction,
then BAS and ESP are also deactivated. There
is an increased risk of your vehicle skidding in
certain situations.
You should always adapt your driving style to
suit the prevailing road and weather condi-
tions.
Braking If ABS intervenes when braking, you will feel
ap ulsing in the brake pedal.
X If ABS intervenes: continue to depress the
brake pedal with force until the braking sit-
uation is over.
X To make afull brake application:
depress the brake pedal with full force.
The pulsating brake pedal can be an indica-
tion of hazardous road conditionsa nd func-tions as
areminder to take extrac are while
driving. G
WARNING
Do not depress the brake pedal several times
in quick succession (pumping). Pumping the
brake pedal reduces the braking effect.Y ou
might otherwise not be able to stop the vehi-
cle in time and could cause an accident.
Depress the brake pedal firmly and smoothly. BAS (Brake Assist)
i Observe the "Important safety notes" sec-
tion (Y page 61).
BAS operates in emergenc ybraking situa-
tions. If you depress the brake pedal quickly,
BAS automatically boosts the braking force,
thus shortening the stopping distance.
X Keep the brake pedal firmly depressed until
the emergenc ybraking situation is over.
ABS prevent sthe wheels from locking.
The brakes will function as usual once you
release the brake pedal. BAS is deactivated. G
WARNING
If BAS has malfunctioned, the braking system
remains available with full brake boosting
effect .However, braking force is not auto-
matically increased in emergenc ybraking sit-
uations and the stopping distance may
increase. BAS PLUS (Brake Assist System
PLUS)
BAS PLUS is only available on vehicles with
DISTRONIC PLUS.
i Observe the "Important safety notes" sec-
tion (Y page 61).
BAS PLUS provides braking assistance in haz-
ardous situations at speeds of over
30 km/ha nd uses rada rsensor technology
to assess the traffic situation. 62
