EBD (electronic brake force distribu-
tion)
General notes EBD monitors and controls the brake pressure
on the rear wheels to improve driving stability
while braking.
Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page 68). G
WARNING
If EBD is malfunctioning, the rear wheels can
lock, e.g. under full braking. This increases the risk of skidding and an accident.
You should therefore adapt your driving style
to the different handling characteristics. Have the brake system checked at a qualified spe-
cialist workshop.
Observe information regarding indicator and
warning lamps (Y page 283) as well as display
messages (Y page 252). ADAPTIVE BRAKE
ADAPTIVE BRAKE enhances braking safety and
offers increased braking comfort. In addition to
the braking function, ADAPTIVE BRAKE also has the HOLD function (Y page 186) and hill start
assist (Y page 147). PRE-SAFE
®
Brake
General information PRE-SAFE
®
Brake can help you to minimise the
risk of collision with the vehicle in front or a
pedestrian and to reduce the effects of such a
collision. If PRE-SAFE ®
Brake has detected a
danger of collision, you will be warned visually
and audibly as well as by automatic braking.
i Observe the important safety notes in the
"Driving safety systems" section (Y page 68).
PRE ‑SAFE ®
Brake is available only in vehicles
with the Driving Assistance Plus package. For PRE-SAFE
®
Brake to assist you when driving,
the radar sensor system and the camera system must be switched on and operational.
With the help of the radar sensor system and the
camera system, PRE-SAFE ®
Brake can detect
obstacles that are in front of your vehicle for an
extended period of time.
In addition, pedestrians in the path of your vehi-
cle can be detected.
PRE-SAFE ®
Brake detects pedestrians using
typical characteristics such as the body con-
tours and posture of a person standing upright.
i Observe the restrictions described in the
"Important safety notes" section
(Y page 77).
Important safety notes G
WARNING
PRE-SAFE ®
Brake will initially brake your vehi-
cle by a partial application of the brakes if a
danger of collision is detected. There may be
a collision unless you brake yourself. Even
after subsequent full application of the brakes
a collision cannot always be avoided, partic-
ularly when approaching at too high a speed.
There is a risk of an accident.
Always apply the brakes yourself and try to
take evasive action, provided it is safe to do
so.
If you partially apply the brakes, the vehicle is
braked with up to 50% of the full brake pressure. G
WARNING
PRE-SAFE ®
Brake cannot always clearly iden-
tify objects and complex traffic conditions.
In these cases, PRE-SAFE ®
Brake may:
R give an unnecessary warning and then
brake the vehicle
R neither give a warning nor 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

WARNING
PRE-SAFE ®
Brake cannot always clearly iden-
tify people, especially if they are moving. In
these cases, PRE-SAFE ®
Brake cannot inter-
vene. 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.
To maintain the appropriate distance to the
vehicle in front and thus prevent a collision, you
must apply the brakes yourself. G
WARNING
PRE-SAFE ®
Brake does not react:
R to small people, e.g. children
R to animals
R to oncoming vehicles
R to crossing traffic
R when cornering
As a result, PRE-SAFE ®
Brake may neither
give warnings nor intervene in all critical sit-
uations. There is a risk of an accident.
Always pay careful attention to the traffic sit- uation and be ready to brake.
In the event of snowfall or heavy rain, detection can be impaired.
Detection by the radar sensor system is also
impaired in the following situations:
R dirt on the sensors or obscured sensors
R interference by other radar sources
R strong radar reflections, for example, in multi-
storey car parks
R a narrow vehicle travelling in front, e.g. a
motorcycle
R a vehicle travelling in front on a different line
Detection by the camera system is also impaired
in the following situations:
R dirt on the camera or obscured camera
R glare on the camera system, e.g. from the sun
being low in the sky R
darkness
R if:
- pedestrians move quickly, e.g. into the path
of the vehicle
- the camera system no longer detects a
pedestrian as a person due to special cloth-
ing or other objects
- a pedestrian is concealed by other objects
- the typical outline of a pedestrian is not
distinguishable from the background
Following damage to the front end of the vehicle, have the radar sensor settings and operation
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.
Following damage to the windscreen, have the
configuration and operation of the camera sys-
tem checked at a qualified specialist workshop.

Driving safety systemsSafety

The PRE-SAFE
®
Brake function can also brake
the vehicle automatically under the following
conditions:
R the driver and front passenger have their seat
belts fastened
R the vehicle speed is between approximately
7 km/h and 200 km/h
At speeds of up to approximately 70 km/h, PRE-
SAFE ®
Brake can also detect:
R stationary objects in the path of your vehicle,
e.g. stopped or parked vehicles
R pedestrians in the path of your vehicle
i If an increased danger of collision exists,
preventative passenger protection measures
(PRE-SAFE ®
) are triggered (Y page 55).
If the danger of collision with the vehicle in front remains and you do not brake, take evasive
action or accelerate quickly, the vehicle may
perform automatic emergency braking up to the
point of full brake application. Automatic full
brake application is not performed until imme-
diately prior to an imminent accident.
You can prevent the engagement of PRE-SAFE ®
Brake at any time by:
R depressing the accelerator pedal further
R activating kickdown
R releasing the brake pedal
The braking action of PRE-SAFE ®
Brake is ended
automatically if:
R you manoeuvre to avoid the obstacle
R the danger of collision has passed
R an obstacle is no longer detected in front of
your vehicle STEER CONTROL
General information STEER CONTROL helps you by transmitting a
noticeable steering force to the steering wheel
in the direction required for vehicle stabilisation.
This steering support is provided in particular if:
R both right wheels or both left wheels are on a
wet or slippery road surface when you brake
R the vehicle begins to skid Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page 68).
No steering support is provided from STEER
CONTROL, if: R ESP ®

General notes The Intelligent Light System is a system that
adjusts the headlamps to suit the prevailing
driving and weather conditions. It offers
advanced functions for improved illumination of the road surface, e.g. depending on the vehicle
speed or weather conditions. The system
includes the active light function, cornering light
function, motorway mode and extended-range
fog lamps. The system is active only when it is
dark.
You can activate/deactivate the Intelligent
Intelligent
Light System Light System function using the on-board
computer (Y page 243).
Active light function The active light function is a system that moves
the headlamps according to the steering move-
ments of the front wheels. In this way, relevant
areas remain illuminated while you are driving.
This allows you to recognise pedestrians,
cyclists and animals sooner.
Active: when the lights are switched on.
Vehicles with Lane Keeping Assist: the active
light function evaluates the course of the lane in which you are driving and adjusts the light in
advance. Cornering light function The cornering light function improves the illu-
mination of the road over a wide angle in the
direction you are turning, enabling better visi-
bility in tight bends, for example. It can be acti-
vated only when the dipped-beam headlamps
are switched on.
Active:
R if you are driving at speeds below 40 km/h
and switch on the turn signal or turn the steer-
ing wheel
R if you are driving at speeds between 40 km/h
and 70 km/h and turn the steering wheel
The cornering light function may remain lit for a short time, but is automatically switched off
after no more than three minutes.
Cornering light function with roundabout
function:
The cornering light function is activated on both
sides before entering a roundabout through an
evaluation of the current GPS position of the
vehicle. It remains active until after the vehicle
has left the roundabout. In this way, pedestrians crossing the road, for example, are illuminated
by your vehicle in good time.
Only vehicles with the COMAND multimedia sys-
tem have this function.
Motorway mode Motorway mode increases the range of the
beam.
Active:if you are driving at a speed above
110 km/h and do not make any large steering
movements for at least 1000 m or if you are
driving at a speed above 130 km/h.
Not active: if you are driving at speeds below
80 km/h following activation.
Extended range fog lamps The extended-range fog lamps reduce the glare
experienced by the driver and improve the illu-
mination of the edge of the carriageway.
Active: if you are driving at speeds below
70 km/h and you switch on the rear fog lamp.
Not active: if, following activation, you are driv-
ing at speeds above 100 km/h or if you switch
off the rear fog lamp. 118

Running-in notes
Important safety notes
In certain driving and driving safety systems, the sensors adjust automatically while a certain dis-
tance is being driven after the vehicle has been delivered or after repairs. Full system effective-
ness is not reached until the end of this teach-in process.
Brake pads/linings and discs that either are new or have been replaced achieve optimum braking
effect only after several hundred kilometres of
driving. Compensate for the reduced braking
effect by applying greater force to the brake
pedal. The first 1500 km
The more you treat the engine with sufficient
care at the start, the more satisfied you will be
with the engine performance later on.
R You should therefore drive at varying road
speeds and engine speeds for the first
1500 km.
R Avoid overstraining the vehicle during this
period, e.g. driving at full throttle.
R When shifting gears manually, shift up in good
time, before the rev counter needle reaches
Ô of the way to the red area of the rev counter
display.
R Do not shift down a gear manually in order to
brake.
R Try to avoid depressing the accelerator pedal
beyond the pressure point (kickdown).
After 1500 km, you can increase the engine
speed gradually and accelerate the vehicle to
full speed.
You should also observe these notes on running- in if the engine or parts of the drive train on your
vehicle have been replaced.
Always observe the maximum permissible
speed. Driving
