Bas Plus - Mercedes-Benz CLS Operator's Manual

BAS PLUS (Brake Assist System Plus)
i Observe the "Important safety notes"
section ( Y page 63).
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.
BAS PLUS can also react to stationary
obstacles, e.g. stopped or parked vehicles, at
speeds of up to approximately 40 mph
(70 km/h).
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
For speeds above 20 mph (30 km/h): if you
apply the brakes forcefully, BAS PLUS
automatically increases the braking force to
a level suitable for the traffic conditions.
For speeds below 20 mph (30 km/h): if you
apply the brakes, 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

Keep the brake pedal depressed until the
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.

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

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.

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.
In particular, the detection of obstacles can
be impaired if there is:
dirt on the sensors or anything else

As a result, BAS PLUS may not intervene in all
critical situations. There is a risk of an
accident.
Always pay careful attention to the traffic
situation and be ready to brake.
Following damage to the front end of the
vehicle, have the configuration and operation
of the radar sensors checked at a qualified
