G
Risk of accident
Pay particular attention to the traffic condi-
tions if the distance warning lamp ·in the
instrument cluster lights up or an intermittent
warning tone sounds. If necessary, brake or
manoeuvre to avoid an obstacle.
In addition, at speeds of around 30 km/h or
more, PRE-SAFE ®
Brake can:
R brake the vehicle gently and automatically
within a speed range of up to around
180 km/h
R trigger preventative passenger protection
measures (PRE-SAFE ®
) G
Risk of accident
PRE-SAFE ®
Brake is only an aid to assist you
when driving. You are responsible for main-
taining a safe distance from other vehicles,
the vehicle's speed and for braking in good
time. Always pay attention to the traffic con-
ditions. Otherwise, you may recognise dan-
gers too late, cause an accident and injure
yourself and others.
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. If you approach an obstacle
and PRE-SAFE ®
Brake detects a risk of a col-
lision, the system will initially alert you both
visually and acoustically. If you do not brake
or steer, the vehicle will automatically brake
slightly. In the event of an increased risk of a
collision, PRE-SAFE ®
is activated
(Y page 42). G
Risk of accident
Only clearly detected obstacles will trigger a
warning and initiate braking assistance by
PRE-SAFE ®
Brake. In particular, the detection of obstacles may
be restricted if there is:
R
dirt on the sensors or the sensors are cov-
ered
R snow or heavy rain
R interference from other radar sources
R strong radar reflections, for example in
multi-storey car parks
PRE-SAFE ®
Brake does not react to persons,
animals, oncoming vehicles and crossing traf-
fic.
PRE-SAFE ®
Brake may not detect narrow
vehicles such as motorcycles or vehicles driv-
ing on a different line. G
Risk of accident
Depending on the vehicle's speed, PRE-
SAFE ®
Brake will brake your vehicle up to
maximum of 4 m/s 2
. This is equivalent to
approximately 40 % of the maximum braking
power of the vehicle. You must also apply the
brakes yourself to avoid a collision.
In order to maintain the appropriate distance
to the vehicle in front and thus prevent a
crash, you must apply the brakes yourself.
At speeds up to approximately 70 km/h,
PRE-SAFE ®
Brake can also detect stationary
obstacles, for example stopped or parked
vehicles. G
Risk of accident
If, in a critical driving situation, you do not
receive a visual and acoustic warning:
R PRE-SAFE ®
Brake did not detect the risk of
a collision
R PRE-SAFE ®
Brake is deactivated
R PRE-SAFE ®
Brake has failed
You must then brake to avoid a collision. Driving safety systems

X
To activate/deactivate: activate or deac-
tivate PRE-SAFE ®
Brake in the on-board
computer (Y page 224).
After activation, the Äsymbol is dis-
played on the left in the driver display.
Vehicles with COMAND and a navigation sys-
tem*: the radar sensor system is switched off
automatically in the vicinity of radio telescope
facilities (Y page 411).
For PRE-SAFE ®
Brake to assist you when driv-
ing, the radar sensor system must be
switched on and operational.
PRE-SAFE ®
Brake does not always clearly
identify complex traffic situations properly.
You can terminate the intervention of PRE-
SAFE ®
Brake in a non-critical driving situation
at any time if:
R an acoustic and visual warning occurs
R the vehicle brakes gently
To end this you can either depress the accel-
erator pedal further, activate kickdown or
release the brake pedal.
The braking intervention of PRE-SAFE ®
Brake
is ended automatically if:
R you manoeuvre to avoid the obstacle.
R you drive slower than approximately
15 km/h.
R there is no longer an obstacle detected in
front of your vehicle.
R there is no longer any danger of a collision.
i While Distronic Plus is activated, PRE-
SAFE ®
Brake remains passive.
Following a collision or crash-related damage
to the front end of the vehicle, have the con-
figuration and operation of the radar sensors
checked. Choose a qualified specialist work-
shop for this which has the necessary spe-
cialist knowledge and tools for the work
required. Mercedes-Benz recommends that
you use a Mercedes-Benz Service Centre for
this purpose. Anti-theft systems

the "Wipe with washer fluid" function is oper-
ated five times while the lights are on and the
engine is running. When you switch off the
ignition, the automatic headlamp cleaning
system is reset and counting is resumed
from 0. Intelligent Light System
The Intelligent Light System is a system which
adjusts the headlamps automatically to suit
the prevailing driving and weather conditions.
The bi-xenon headlamps offer enhanced func-
tions to improve illumination of the road sur-
face, e.g. depending on the vehicle speed or
weather conditions. The system includes the
active light system, cornering light function,
motorway mode and extended range fog-
lamps. The system is only active when it is
dark. Active light system The active light function is a system that
moves the headlamps according to the steer-
ing movements of the front wheels. In this
way, relevant areas remain illuminated while
driving. This allows you to recognise pedes-
trians, cyclists and animals.
Cornering light
The cornering light function improves the illu-
mination of the road surface in the broad
direction you are turning, e.g. making it easier
to see in tight corners. It can only be activated
when the dipped-beam headlamps are
switched on.
Active:
R
if you are driving at speeds below
40 km/h, the cornering light function is
activated either by the turn signal or by the
steering wheel being turned.
