In particular, the detection of obstacles can
be impaired if there is:
R
dirt on the sensors or anything else
covering the sensors
R
snow or heavy rain
R
interference by other radar sources
R
the possibility of strong radar reflections,
for example in parking garages
R
a narrow vehicle traveling in front, e.g. a
motorbike
R
a vehicle traveling in front on a different line
relative to the center of your vehicle
G
WARNING
BAS PLUS does not react:
R
to people or animals
R
to oncoming vehicles
R
to crossing traffic
R
when cornering
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
specialist workshop. This also applies to
collisions at low speeds where there is no
visible damage to the front of the vehicle.
If BAS PLUS is not available due to a
malfunction in the radar sensor system, the
brake system remains available with full
brake boosting effect and BAS.

WARNING
If ESP
®
is malfunctioning, ESP
®
is unable to
stabilize the vehicle. Additionally, further
driving safety systems are deactivated. This
increases the risk of skidding and an accident.
Drive on carefully. Have ESP
®
checked at a
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
®
may
otherwise destroy the brake system.
Vehicles without 4MATIC: when towing your
vehicle with the rear axle raised, it is
important that you observe the notes on
ESP
®
(
Y
page 491).
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
®
is not
available due to a malfunction.
Observe the information on warning lamps
(
Y
page 431) and display messages which
may be shown in the instrument cluster
(
Y
page 391).
If ESP
®
detects that the vehicle is deviating
from the direction desired by the driver, one
or more wheels are braked to stabilize the
vehicle. The engine output is also modified to
keep the vehicle on the desired course within
physical limits. ESP
®
assists the driver when
pulling away on wet or slippery roads. ESP
®
can also stabilize the vehicle during braking.
If ESP
®
intervenes, the
÷
ESP
®
warning
lamp flashes in the instrument cluster.
If ESP
®
intervenes:
X
Do not deactivate ESP
®
under any
circumstances.
X
Only depress the accelerator pedal as far
as necessary when pulling away.
X
Adapt your driving style to suit the
prevailing road and weather conditions.
