cle when braking and the braking distance
may increase.
If ABS is deactivated due to a malfunction,
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.
The pulsating brake pedal can be an indica-
tion of hazardous road conditions and func-
tions as a reminder to take extra care while
driving.
BAS (Brake Assist)
BAS operates in emergency braking 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 emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will function as usual once you
release the brake pedal. BAS is deactivated.
G
Risk of accident
If BAS has malfunctioned, the braking system
remains available with full brake boosting
effect. However, braking force is not auto-
matically increased in emergency braking sit-
uations and the stopping distance may
increase.
BAS PLUS (Brake Assist PLUS)
BAS PLUS provides braking assistance in haz-
ardous situations and uses radar sensor tech-
nology to assess the traffic situation.
G
Risk of accident
BAS PLUS is only an aid to assist you when
driving. You are responsible for maintaining a
safe distance from other vehicles, for the vehi-
cle's speed and for braking in good time.
Always pay attention to the traffic conditions.
Otherwise, you may recognise dangers too
late, cause an accident and injure yourself
and others.
BAS PLUS can detect obstacles that are in the
path of your vehicle for an extended period of
time. Should you approach a detected obsta-
cle quickly, BAS PLUS calculates the braking
force necessary to avoid a rear-end collision.
Should you additionally apply the brakes, BAS
PLUS will automatically increase the braking
force to a level suitable for the traffic condi-
tions.
If BAS PLUS demands particularly high brak-
ing force, PRE-SAFE
®
is activated simultane-
ously.
X
Keep the brake pedal depressed until the
emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will work normally again when:
R
you release the brake pedal
R
no obstacle is detected in front of your
vehicle
R
there is no longer any danger of a rear-end
collision
BAS PLUS is then deactivated.
At speeds up to approximately 70 km/h, BAS
PLUS can also detect stationary obstacles,
for example, stopped or parked vehicles.
The radar sensor system is switched off auto-
matically in the vicinity of radio telescope
facilities (
Y
page 324).
For BAS PLUS to assist you when driving, the
radar sensor system must be switched on and
operational. You can check this by activating
DISTRONIC PLUS (
Y
page 160) or via the
"radar sensor" function in the on-board com-
puter (
Y
page 208).
G
Risk of accident
Only clearly identified obstacles will initiate
braking assistance by BAS PLUS. In particular,
the detection of obstacles can be restricted if
there is:
