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.
In particular, the detection of obstacles can
be impaired if there is:
dirt on the sensors or anything else
R
covering the sensors
snow or heavy rain
R
interference by other radar sources
R
there are strong radar reflections, for
R
example in parking garages
a narrow vehicle traveling in front, e.g. a
R
motorbike
a vehicle traveling in front on a different line
R
relative to the center of your vehicle
Following damage to the front end of the
vehicle, have the configuration and operation
of the radar sensors checked at a qualified
specialist workshop. This also applies to
collisions at low speeds where there is no
visible damage to the front of the vehicle.
Braking assistance
To prevent a collision with the vehicle in front,
BAS PLUS calculates the brake force
necessary if:
you approach an obstacle, and
R
BAS PLUS has detected a risk of collision
R
When driving at a speed under 20 mph
(30 km/h): if you depress the brake pedal,
BAS PLUS is activated. The increase in brake
pressure will be carried out at the last
possible moment.
When driving at a speed greater than
20 mph (30 km/h): if you depress the brake
pedal sharply, BAS PLUS automatically raises
the brake pressure to a value adapted to the
traffic situation.
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
R
there is no longer a risk of collision
R
no obstacle is detected in front of your
R
vehicle

G WARNING
®
If ESP is malfunctioning, ESP
stabilize the vehicle. Additionally, further
driving safety systems are deactivated. This
increases the risk of skidding and an accident.
Drive on carefully. Have ESP
qualified specialist workshop.
! Vehicles with 4MATIC: switch off the
ignition when the parking brake is being
tested on a brake dynamometer.
Application of the brakes by ESP
otherwise destroy the brake system.
Vehicles without 4MATIC: observe the notes

on ESP ( page 330) when towing the
Y
vehicle with a raised rear axle.

ESP is deactivated if the å warning lamp
in the instrument cluster lights up
continuously when the engine is running.
If the ÷ warning lamp and the å
warning lamp are lit continuously, ESP
