cally if:
R an airbag has been triggered or
R the vehicle decelerates rapidly from a speed
of above 70 km/h and comes to a standstill
The hazard warning lamps switch off automati-
cally if the vehicle reaches a speed of above
10 km/h again after a full brake application.
The hazard warning lamps continue to operate
even if the ignition is switched off. Intelligent Light System
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

Overview of climate control systems
General notes
Observe the settings recommended on the fol-
lowing pages. Otherwise, the windows could
mist up.
To prevent the windows from misting up:
R switch off climate control only briefly
R activate air-recirculation mode only briefly
R switch on "Cooling with air dehumidification"
R activate the "Windscreen demisting" function
briefly, if required
Climate control regulates the temperature and
air humidity in the vehicle interior. The interior
filter cleans the air, thus improving the interior
climate.
The "Cooling with dehumidification" function is
available only when the engine is running. Opti-
mum climate control is achieved only with the
side windows and roof closed.
The residual heat function can be activated or
deactivated only with the ignition switched off
(Y page 135). The integrated filter filters out most particles of
dust and soot and completely filters out pollen.
It also reduces gaseous pollutants and odours. A
clogged filter reduces the amount of air supplied to the vehicle interior. For this reason, you
should always observe the interval for replacing
the filter, which is specified in the Service Book-
let. As this depends on environmental condi-
tions, e.g. heavy air pollution, the interval may
be shorter than stated in the Service Booklet.
i Ventilate the vehicle for a brief period during
warm weather, e.g. using the convenience
opening feature (Y page 96). This will speed
up the cooling process and the desired inte-
rior temperature will be reached more
quickly.
i It is possible that the blower may be activa-
ted automatically 60 minutes after the key
has been removed depending on various fac-
tors, e.g. the outside temperature. The vehi-
cle is then ventilated for 30 minutes to dry the
automatic climate control.

briefly until the windscreen is clear again.
R Use the "Air-recirculation mode" function only
briefly, e.g. if there are unpleasant outside
odours or when in a tunnel. The windows
could otherwise mist up as no fresh air is
drawn into the vehicle in air-recirculation
mode.
R Vehicles with THERMATIC with auxiliary heat-
ing or THERMOTRONIC: use the "Residual
heat" function if you want to heat or ventilate
the vehicle interior when the ignition is
