System limits
The automatic driving lights control is no sub‐
stitute for your individual judgement of when it
is necessary to switch on the lights.
The sensors are unable, for instance, to recog‐
nise fog or hazy weather. In such situations,
switch on the lights manually to avoid any
safety risk.
Daytime driving lights Switch position:
,
The daytime driving lights illuminate with the
ignition switched on.
Activating/deactivating
In some countries daytime driving lights are
compulsory, which is why the daytime driving
lights cannot be deactivated.
On the Control Display:
1."Settings"2."Lights"3."Daytime driving lights"
The setting is saved for the currently used pro‐
file.
Adaptive HeadlightsPrinciple
Adaptive Headlights is a variable headlight
control system that makes it possible to illumi‐
nate the road surface responsively.
The beams from the headlights follow the road
ahead on the basis of the steering angle and
other parameters.
Depending on the speed, the variable light dis‐
tribution ensures even better illumination of
the roadway.
The light distribution is automatically adapted
to the speed. The city light is switched on if the
speed of 50 km/h, approx. 30 mph is not ex‐
ceeded while accelerating or if the speed of
40 km/h, approx. 25 mph is undercut while
braking. The motorway light is switched on at a speed higher than 110 km/h, 68 mph after ap‐
proximately 30 seconds or as of a speed of
140 km/h, 87 mph.
Activating Switch position
with the ignition switched
on.
So as not to dazzle oncoming vehicles, the
adaptive cornering light does not swivel to the
driver's side when stationary.
A cornering light is activated automatically de‐
pending on the steering angle or use of the
turn indicators.
The cornering light may be switched on when
driving in reverse, irrespective of the steering
angle.
Malfunction
A Check Control message is displayed.
Adaptive Headlights are faulty or have failed.
Have the system checked as soon as possible.
High-beam assistance
Principle When low-beam headlights are switched on,this system automatically switches the high-
beam headlights on and off or fades out the
areas which dazzle oncoming vehicles. This
process is controlled by a camera on the front
of the rear-view mirror. It ensures that the
high-beam headlights are switched on when‐
ever the traffic situation allows. You can also
control the lights yourself at any time and
switch them on and off as usual. The high-
beam headlights are not switched on by the
system in the low speed range.

The indicator light in the instrument
cluster is illuminated.
When the low-beam headlights are on, the
beam is dipped and returned to full beam auto‐
matically.
The system responds to light from oncoming
traffic and traffic driving ahead of you, and to
adequate lighting, for example in built-up
areas.
The blue indicator light in the instru‐
ment cluster illuminates if the high
beam is switched on by the system.
Depending on the version of the system instal‐
led in the vehicle, the high-beam lights may
not be switched off for oncoming vehicles, but
only the areas which dazzle the oncoming ve‐
hicles are faded out. In this case, the blue indi‐
cator light continues to illuminate.
Raising and dipping manually▷High-beam headlights on, arrow 1.▷High-beam headlights off/headlight flasher,
arrow 2.
The high beam assistance can be deactivated
by manually raising and dipping.
To reactivate high-beam assistance, press the
button on the turn indicator lever, see
page 101.
System limits
The high-beam assistance cannot replace the
personal decision to use the high-beam head‐
lights. Thus, dip manually in situations requir‐
ing such.
In the following situations, the system will not
operate or its operation will be impaired and
your intervention may be required:
▷During extremely unfavourable weather
conditions such as fog or heavy precipita‐
tion.▷When detecting poorly-lit road users such
as pedestrians, cyclists or horseback riders
or carts, and when trains or ships are close
to the road, or when game are passing
across the road.▷On narrow bends, steep uphill or downhill
gradients, at traffic junctions or if your view
of oncoming vehicles on a motorway is ob‐
structed.▷In poorly-lit towns and where there are very
reflective signs.Seite 101LightsControls101

Runflat indicator RPA
Principle The system identifies a loss of tyre pressure
by comparing the speeds of rotation of the in‐
dividual wheels while the vehicle is in motion.
If a tyre loses pressure, its diameter changes.
This in turn alters the rotational speed of the
corresponding wheel. This is detected and re‐
ported as a flat tyre.
The system does not measure the tyre pres‐
sures as such.
Operating requirements
The system must have been initialised with
correct tyre inflation pressure, otherwise relia‐
ble signalling of a flat tyre cannot be assured.
Each time the tyre pressure is adjusted or a
tyre or wheel is changed, initialise the system
again.
Status display The current status of the runflat indicator can
be shown on the Control Display, for example
whether the runflat indicator is active.
On the Control Display:1."Vehicle information"2."Vehicle status"3. "Flat Tyre Monitor (RPA)"
The status is displayed.
Initialising
On initialisation, the current tyre pressures are
stored as a reference for detection of a flat tyre. The initialisation is started by confirming
the correct tyre inflation pressures.
When driving with snow chains fitted, do not
initialise the system.
On the Control Display:
1."Vehicle information"2."Vehicle status"3. "Perform reset"4.Start the engine – do not drive off.5.Start the initialisation with "Perform reset".6.Drive off.
Initialising is completed while the vehicle is in
motion; this process can be interrupted at any
time.
Initialising resumes automatically when you
continue your journey.
Message of a flat tyre The yellow warning lamp is illuminated.
A Check Control message is shown.
There is a flat tyre or substantial loss of
tyre pressure.
1.Reduce your speed and carefully stop the
vehicle. Avoid violent or sudden braking
and steering manoeuvres.2.Determine which wheel is damaged. Do
this by checking the tyre inflation pres‐
sures with the aid of the Mobility System. If
all tyres are inflated to the correct pres‐
sures, the runflat indicator might not have
been initialised. In this case initialise the
system.3.Remedy the flat tyre with the Mobility Sys‐
tem or replace the damaged wheel.
System limits
A natural, even loss of tyre pressurein all four
tyres that occurs over time is not detected.
Consequently, check the tyre inflation pres‐
sure at regular intervals.
No warning can be given in the event of sud‐
den tyre failure caused by external factors.
In the following situations, the system could be
slow to respond or operate incorrectly:
▷If the system has not been initialised.▷Journey on snow-covered or slippery sur‐
faces.Seite 109SecurityControls109

▷Dynamic driving style, causing the drive
gears to spin, high lateral acceleration.▷Driving with snow chains.
Intelligent Safety
Principle
Intelligent Safety permits central operation of
driver assistance systems.
Depending on equipment, Intelligent Safety
consists of one or more systems which can
help to avoid the risk of a collision. These sys‐
tems are automatically active each time you
start the engine with the start/stop button:
▷Front-end collision warning with city brak‐
ing function, see page 111.▷Person warning, see page 113.

Front-end collision warning
with city braking function
Principle The system can help avoid accidents. If an ac‐
cident cannot be avoided, the system helps to
reduce the collision speed.
The system warns of the possible risk of colli‐
sion and brakes automatically, as necessary.
The automatic braking intervention is done
with limited force and duration.
The system is controlled by a camera in the
area of the rear-view mirror.
The front-end collision warning is also avail‐
able if the Cruise Control is disabled.
When deliberately approaching a vehicle, the
approach control warning and braking inter‐
vention are activated later to avoid unjustified
system responses.
General
The system warns from approximately 5 km/h,
approximately 3 mph in two stages of any risk
of collision with vehicles. The timing of these
warnings may vary depending on the current
driving situation.
Up to approximately 60km/h, 35 mph.
Detection range
Objects are taken into account if they are de‐
tected by the system.
