Bas (Brake Assist System) - Mercedes-Benz C-Class Operator's Manual

functions as a reminder to take extra care
while driving.

BAS (Brake Assist System)

G 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.
Keep the brake pedal depressed firmly until
X
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.
BAS PLUS (Brake Assist System Plus)
i
Observe the "Important safety notes"
section ( page 62).
Y
BAS PLUS is only available in vehicles
equipped with DISTRONIC PLUS.
BAS PLUS provides braking assistance in
hazardous situations at speeds greater than
4 mph (7 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.
Driving safety systems
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
At a speed greater than 20 mph
(30 km/h): if you depress the brake sharply,
BAS PLUS automatically raises the brake
pressure to a value adapted to the traffic
situation.
At a speed less than 20 mph (30 km/h): if
you depress the brake, BAS PLUS is
activated. Braking is performed as late as
possible.
If BAS PLUS demands particularly high
braking force, preventative passenger
protection measures (PRE-SAFE
activated simultaneously.
Keep the brake pedal depressed until the
X
emergency braking situation is over.
ABS prevents the wheels from locking.
BAS PLUS is deactivated and the brakes
function as usual, if:
you release the brake pedal.

there is no longer any danger of a rear-end

collision.
no obstacle is detected in front of your

vehicle.
For BAS PLUS to assist you when driving, the
radar sensor system must be:

Y
If the radar sensor system is malfunctioning,
BAS PLUS will not be available. The brake
system is still available with complete brake
boosting effect and BAS.
G WARNING
BAS PLUS cannot always clearly identify
objects and complex traffic situations. BAS
PLUS cannot intervene in these cases. There
is a risk of an accident.
Always pay careful attention to the traffic
situation and be ready to brake.
