2013 MERCEDES-BENZ CLA-CLASS fog light

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 vis-
ibility in tight bends, for example. The corner-
ing light function can only be activated when
the dipped-beam headlamps are switched on.
Active:
R if you are driving at speeds below
40 km/h and the turn signal is activated or
the steering wheel is turned.
R if you are driving at speeds between
40 km/h and 70 km/h and turn the steer-
ing wheel.
Not active: if you are driving at speeds above
40 km/h or switch off the turn signal or turn
the steering wheel to the straight-ahead posi-
tion.
The cornering lamp may remain lit for a short
time, but is automatically switched off after
no more than three minutes.
Motorway mode
Motorway mode increases the range of the
beam.
Active:
R if you are driving at speeds above
110 km/h and do not make any large steer-
ing movements for 1000 m
R if you are driving at speeds above
130 km/h
Not active: if you are driving at speeds below
80 km/h following activation.
Extended range foglamps
The extended range foglamps reduce the
glare experienced by the driver and improve
the illumination of the edge of the carriage-
way.
Active: if you are driving at speeds below
70 km/h and you switch on the rear foglamp.
Not active: if you are driving at speeds above
100 km/h or if you switch off the rear foglamp
following activation.
Adaptive Highbeam Assist
Important safety notes
GWARNING
Adaptive Highbeam Assist does not recognise
road users:
R who have no lights, e.g. pedestrians
R who have poor lighting, e.g. cyclists
R whose lighting is blocked, e.g. by a barrier
Exterior lighting111Lights and windscreen wipersZProCarManuals.com

In very rare cases, Adaptive Highbeam Assist
recognises road users too late or not at all. In
this, or in similar situations, the automatic
main-beam headlamps will not be deactivated
or activated regardless. There is a risk of an
accident.
Always carefully observe the traffic conditions
and switch off the main-beam headlamps in
good time.
Adaptive Highbeam Assist cannot take into
account road, weather or traffic conditions.
Adaptive Highbeam Assist is only an aid. You
are responsible for adjusting the vehicle's
lighting to the prevailing light, visibility and
traffic conditions.
In particular, the detection of obstacles can
be restricted if there is:
R poor visibility, e.g. due to fog, heavy rain or
snow
R dirt on the sensors or the sensors are
obscured
General notes
You can use this function to set the head-
lamps to change between dipped beam and
main beam automatically. The system recog-
nises vehicles with their lights on, either
approaching from the opposite direction or
travelling in front of your vehicle, and conse-
quently switches the headlamps from main
beam to dipped beam.
The system automatically adapts the dipped-
beam headlamp range depending on the dis-
tance to the other vehicle. Once the system
no longer detects any other vehicles, it reac-
tivates the main-beam headlamps.
The system's optical sensor is located behind
the windscreen near the overhead control
panel.

imately 45 km/h:
The headlamp range is set automatically
depending on the distance between the
vehicle and other road users.
If you are driving at speeds above approx-
imately 55 km/h and no other road users
are detected:
The main-beam headlamps are switched on
automatically. The K indicator lamp in
the instrument cluster also lights up.112Exterior lightingLights and windscreen wipers

The bulb may explode if:
R you touch it
R it is hot
R you drop it
R you scratch it
Only operate bulbs in enclosed lamps
designed for that purpose. Only fit spare
bulbs of the same type and the specified volt-
age.
Marks on the glass tube reduce the service
life of the bulbs. Do not touch the glass tube
with your bare hands. If necessary, clean the
glass tube when cold with alcohol or spirit and
rub it off with a lint-free cloth.
Protect bulbs from moisture during opera-
tion. Do not allow bulbs to come into contact
with liquids.
There are bulbs other than the xenon bulbs
that you cannot replace yourself. Replace
only the bulbs listed ( Y page 115). Have the
bulbs that you cannot replace yourself
replaced at a qualified specialist workshop.
If you require assistance replacing bulbs, con-
sult a qualified specialist workshop.
If the new bulb still does not light up, consult
a qualified specialist workshop.
Bulbs and lamps are an important aspect of
vehicle safety. You must therefore make sure
that these function correctly at all times.
Have the headlamp setting checked regularly.

Windscreen wipers
Switching the windscreen wipers on/
off
! Do not operate the windscreen wipers
when the windscreen is dry, as this could
damage the wiper blades. Moreover, dust
that has collected on the windscreen can
scratch the glass if wiping takes place when
the windscreen is dry.
If it is necessary to switch on the wind-
screen wipers in dry weather conditions,
always operate them using washer fluid.
! If the windscreen wipers leave smears on
the windscreen after the vehicle has been
washed in an automatic car wash, this may
be due to wax or other residue. Clean the
windscreen with washer fluid after an auto-
matic car wash.

Towing a trailer
For vehicles with a trailer tow hitch, the min-
imum required length for parking spaces is
slightly increased.

Parking Assist is no longer available. PARK-
TRONIC is deactivated for the rear area.
Reversing camera
General notes
Reversing camera : is in the boot lid handle.
The reversing camera is an optical parking
and manoeuvring aid. It uses guide lines to
show the area behind your vehicle in the
Audio/COMAND display.
The area behind the vehicle is displayed as a
mirror image, as in the rear-view mirror.
The reversing camera is protected from rain-
drops and dust by means of a flap. When the
reversing camera is activated, this flap opens.
Only once the manoeuvring process has been
completed and the reversing camera has
switched off does the flap close again. For
technical reasons, the flap may remain open
briefly after the reversing camera has been
deactivated. If you switch off the engine, the
flap will also close.
i The text of messages shown in the
COMAND display depends on the language
setting. The following are examples of
reversing camera messages in the
COMAND display.
Observe the notes on cleaning
( Y page 291).
Important safety notes
The reversing camera is only an aid. It is not
a substitute for your attention to the imme-
diate surroundings. The responsibility for safe
manoeuvring and parking remains with you.
Make sure that there are no persons, animals
or objects in range while manoeuvring and
parking.
Under the following circumstances, the
reversing camera will not function, or will
function in a limited manner:
R if the tailgate is open
R in heavy rain, snow or fog
R at night or in very dark places
R if the camera is exposed to very bright light
R if the area is lit by fluorescent light or LED
lighting (the display may flicker)
R if there is a sudden change in temperature,
e.g. when driving into a heated garage in
winter
R if the camera lens is dirty or obstructed
R if the rear of your vehicle is damaged. In
this case, have the camera position and
setting checked at a qualified specialist
workshop.
