Braking
If ABS intervenes: continue to depress the
X
brake pedal vigorously until the braking
situation is over.
To make a full brake application:
X
depress the brake pedal with full force.
If ABS intervenes when braking, you will feel
a pulsing in the brake pedal.
The pulsating brake pedal can be an
indication of hazardous road conditions, and
functions as a reminder to take extra care
while driving.

WARNING
If BAS is malfunctioning, the braking distance
in an emergency braking situation is
increased. There is a risk of an accident.
In an emergency braking situation, depress
the brake pedal with full force. ABS prevents
the wheels from locking.
BAS operates in emergency braking
situations. If you depress the brake pedal
quickly, BAS automatically boosts the braking
force, thus shortening the stopping distance.
The brakes will function as usual once you
release the brake pedal. BAS is deactivated.

BAS PLUS is only available in vehicles
equipped with DISTRONIC PLUS.
BAS PLUS provides braking assistance in
hazardous situations at speeds greater than
20 mph (30 km/h) and uses radar sensor
technology to assess the traffic situation.
With the help of the radar sensor system, BAS
PLUS can detect obstacles that are in the
path of your vehicle for an extended period of
time.
At speeds up to 40 mph (70 km/h), BAS PLUS
may also detect stationary obstacles, for
example, stopped or parked vehicles.
To prevent a front-end collision, BAS PLUS
calculates the brake force necessary if:
you approach an obstacle, and
R
BAS PLUS has detected a risk of collision
R
Should you apply the brakes forcefully, BAS
PLUS will automatically increase the braking
force to a level suitable for the traffic
conditions.
If BAS PLUS demands particularly high
braking force, preventative passenger
protection measures (PRE-SAFE

Keep the brake pedal depressed until the
