The brakes will function as usual once you
release the brake pedal. BAS is deactivated.
BAS PLUS (Brake Assist System
PLUS)
BAS PLUS is only available in vehicles
equipped with DISTRONIC PLUS.
i Observe the "Importan tsafety notes"
sectio n(Ypage 64).
BASP LUS provides braking assistance in
hazardous situations at speeds greater than
4m ph (7 km/h) and uses radar sensor
technology to assess the traffic situation.
With the help of the radar senso rsystem, BAS
PLUS can detect obstacles that are in the
path of your vehicle fo ranextended period of
time.
At speed supto40 mph (70 km/h) ,BAS PLUS
may also detect stationar yobstacles, for
example stopped or parked vehicles.
Should you approach an obstacle and BAS
PLUS has detected a risk of collision, BAS
PLUS calculates the brakin gforce necessary
to avoid a rear-end collision.
R When driving at aspee dabove 20 mph
(30 km/h):ify ou depress the brake pedal
sharply, BAS PLUS automatically raises the
brake pressure to a value adapted to the
traffic situation.
R When driving at a speed under 20 mph
(30 km/h):ify ou depress the brake pedal,
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 ®
) are
activated simultaneously.
X Keep the brake pedal depressed until the
emergency braking situation is over.
ABS prevents the wheels from locking. The brakes will work normally again if:
R
you release the brake pedal
R there is no longer any danger of a rear-end
collision
R no obstacle is detected in front of your
vehicle
BAS PLUS is then deactivated.
For BAS PLUS to assist you, the radar sensor
system must be operational. G
WARNING
Adaptive Brake Assist cannot always clearly
identify objects and complex traffic
situations. In these cases, Adaptive Brake
Assist may not intervene. 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:
R dirt on the sensors or anything else
covering the sensors
R snow or heavy rain
R interference by other radar sources
R there are 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 aresult, 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. 66
Driving safet
ysystemsSafety

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 senso rsystem, the
brake system remains available with full
brake boosting effect and BAS. ESP

(Electronic Stabilit yProgram)
Important safety notes i
Observe the "Important safety notes"
sectio n(Ypage 64). G
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 448).
ESP ®
is deactivated if the åwarning lamp
in the instrument cluster lights up
continuously when the engin eis 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 393) and displaym essages which
may be shown in the instrument cluster
(Y page 353). 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.
i Only use wheels with the recommended
tire sizes. Only then will ESP ®
function
properly.
ETS/4ETS (Electronic Traction System) Traction control is part of ESP
®
.
Traction control brakes the drive wheels
individually if they spin. This enables you to
pull away and accelerate on slippery surfaces,
for example if the road surface is slippery on
one side. On vehicles with 4MATIC, more
drive torque is also transferred to the wheel
or wheels with traction.
Traction control remains active if you
deactivate ESP ®
.
Deactivating/activating ESP ® i
Observe the "Important safety notes"
section (Y page 64). G
WARNING
If you deactivate ESP ®
, ESP ®
no longer
stabilizes the vehicle. There is an increased
risk of skidding and an accident.
Only deactivate ESP ®
in the situations
described in the following. Driving safet
ysystems
67Safety Z

you will be warned visually and acoustically
as well as by automati
cbraking. PRE-SAFE ®
Brake cannot prevent a collision without your
intervention.
Starting at a speed of around 4 mph
(7 km/h), this function warns you if you
rapidly approach a vehicle in front. An
intermittent warning tone will then sound and
the · distance warning lamp willl ight up
in the instrument cluster.
X Brake immediately in order to increase the
distance from the vehicle in front.
or
X Take evasive action provided it is safe to do
so.
Fro maspeed of approximately 4mph
(7 km/h), if the driver and front passenger
have fastened their seat belts, PRE-SAFE ®
Brake can brake the vehicle automatically at
speeds up to approximately 124 mph
(200 km/h).
Due to the nature of the system, particularly
complicated driving condition smay cause
unnecessary warnings or th eunnecessary
intervention of PRE-SAFE ®
Brake.
You can prevent the intervention of the PRE-
SAFE ®
Brake at any time by:
R depressing the accelerator peda lfurther.
R activating kickdown.
R releasing the brake pedal.
The braking action of PRE-SAFE ®
Brake is
ended automatically if:
R you maneuve rto avoid the obstacle.
R there is no longer any danger of a rear-end
collision.
R there is no longer an obstacle detected in
front of your vehicle.
With the help of the radar sensor system,
PRE-SAFE ®
Brake can detect obstacles that
are in front of your vehicle for an extended
period of time.
At speeds up to approximately
40 mph (70 km/h), PRE-SAFE ®
Brake can also detect stationary obstacles such as
stopped or parked vehicles.
If you approach an obstacle and PRE-SAFE
®
Brake detects a risk of collision, the system
will initially alert you both visually and
acoustically. If you do not brake or take
evasive action, the system will warn you by
automatically braking the vehicle gently. If
there is an increased risk of collision,
preventative passenger protection measures
(PRE-SAFE ®
) are activated (Y page 55). If a
risk of collision remains at speeds of over
20 mph (30 km/h) and you do not brake, take
evasive action or significantly accelerate,
automatic emergency braking may be
performed up to and including full brake
application. Automatic emergency braking is
not performed until immediately prior to an
accident that can no longer be avoided. G
WARNING
PRE-SAFE ®
Brake will initially brake your
vehicle by a partial application of the brakes
if a danger of collision is detected. There may
be a collision unless you also brake.
Automatic emergenc ybraking cannot prevent
a collision. There is a risk of an accident.
Always apply the brakes yourself and try to
take evasive action. G
WARNING
PRE-SAFE ®
Brake cannot always clearly
identify objects and complex traffic
conditions.
In these cases, PRE-SAFE ®
Brake may:
R give an unnecessary warning and then
brake the vehicle
R not give a warning or intervene
There is a risk of an accident.
Always pay particular attention to the traffic
situation and be ready to brake, especially if
PRE-SAFE ®
Brake warns you. Terminate the
intervention in a non-critical driving situation. Driving safety systems
