only the turn signal lamp on the
corresponding side of the vehicle will flash.
X To switch off the hazard warning
lamps: press button 0043.
The hazard warning lamps automatically
switch on if:
R an air bag is deployed or
R the vehicle decelerates rapidly from a
speed of above 45 mph (70 km/h) and
comes to a standstill
The hazard warning lamps switch off
automatically if the vehicle reaches a speed
of above 6 mph (10 km/h) again after a full
brake application.
The hazard warning lamps still operate if the
ignition is switched off. Cornering light function
The cornering light function improves the
illumination of the road over a wide angle in
the direction you are turning, enabling better
visibility in tight bends, for example. It can
only be activated when the low-beam
headlamps are switched on.
Active:
R if you are driving at speeds below 25 mph
(40 km/h) and switch on the turn signal or
turn the steering wheel
R if you are driving at speeds between
25 mph (40 km/h) and 45 mph (70 km/h)
and turn the steering wheel
Not active: if you are driving at speeds above
25 mph (40 km/h) or switch off the turn signal or turn the steering wheel to the
straight-ahead position.
The cornering lamp may remain lit for a short
time, but is automatically switched off after
no more than three minutes.
Adaptive Highbeam Assist
General notes You can use this function to set the
headlamps to change between low beam and
high beam automatically. The system
recognizes vehicles with their lights on, either
approaching from the opposite direction or
traveling in front of your vehicle, and
consequently switches the headlamps from
high beam to low beam.
The system automatically adapts the low-
beam headlamp range depending on the
distance to the other vehicle. Once the
system no longer detects any other vehicles,
it reactivates the high-beam headlamps.
The system's optical sensor is located behind
the windshield near the overhead control
panel. Exterior lighting

Useful information
i This Operator's Manual describes all
models and all standard and optional
equipment of your vehicle available at the
time of publication of the Operator's
Manual. Country-specific differences are
possible. Please note that your vehicle may
not be equipped with all features
described. This also applies to safety-
related systems and functions.
i Read the information on qualified
specialist workshops: (Y page 27).Overview of climate control systems
Important safety notes
Observe the settings recommended on the
following pages. The windows could
otherwise fog up.
To prevent the windows from fogging up:
R switch off climate control only briefly
R switch on air-recirculation mode only
briefly
R switch on the cooling with air
dehumidification function
R switch on the defrost windshield function
briefly, if required
Climate control regulates the temperature
and air humidity in the vehicle interior. The air
filter cleans the air, thus improving the
interior climate.
The "Cooling with air dehumidification"
function is only available when the engine is
running. Optimum climate control is only
achieved with the side windows and roof
closed.
The residual heat function can only be
activated or deactivated with the ignition
switched off (Y page 163).
i Ventilate the vehicle for a brief period
during warm weather, e.g. using the
convenience opening feature
(Y page 100). This will speed up the cooling process and the desired interior
temperature will be reached more quickly.
i The integrated filter filters out most
particles of dust and soot and completely
filters out pollen. It also reduces gaseous
pollutants and odors. 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
Maintenance Booklet. As it depends on
environmental conditions, e.g. heavy air
pollution, the interval may be shorter than
stated in the Maintenance Booklet.
i It is possible that the blower may be
activated automatically 60 minutes after
the key has been removed depending on
various factors, e.g. the outside
temperature. The vehicle is then ventilated
for 30 minutes to dry the automatic climate
control. 152

Notes on using climate control
Automatic climate control Below, you can find a number of notes and
recommendations to help you use climate
control optimally.
R Activate climate control using the 0058
rocker switch. The indicator lamp in the
0058 rocker switch lights up.
R Set the temperature to 72 ‡ (22 †).
R Only use the "Windshield defrosting"
function briefly until the windshield is clear
again.
R Only use air-recirculation mode briefly, e.g.
if there are unpleasant outside odors or
when in a tunnel. The windows could
otherwise fog up, since no fresh air is drawn
into the vehicle in air-recirculation mode.
R Use the residual heat function if you want
to heat or ventilate the vehicle interior
when the ignition is switched off. The
residual heat function can only be activated
or deactivated with the ignition switched
off. The residual heat function is switched
off when the ignition is switched on.
If you are controlling the rear climate control
using the front control panel, note the
following:
R If you set rear-compartment climate
control using the front control panel, the
00A4 symbol appears in the rear-
compartment control panel display.
R If the rear-compartment climate control is
set using the front control panel, it cannot
be set at the same time using the rear
control panel. If controlling the rear climate
control from the front control panel is
locked, wait five seconds. You will then be
able to control the rear climate control
using the rear control panel.
R After selecting the rear compartment
settings, the front climate control can be
controlled automatically again via
COMAND after five seconds. Alternatively, you can select "Cancel rear
compartment" in the COMAND air-
conditioning function bar.
ECO start/stop function During automatic engine switch-off, the
climate control only operates at a reduced
capacity. If you require the full climate control
output, you can switch off the ECO start/stop
function by pressing the ECO button

General notes In automatic mode, the set temperature is
maintained automatically at a constant level.
The system automatically regulates the
temperature of the dispensed air, the airflow
and the air distribution.
The automatic mode functions optimally
when the "Cooling with air dehumidification"
function is activated. If necessary, cooling
with air dehumidification can be deactivated.
If you deactivate the "Cooling with air-
dehumidification" function, the air inside the
vehicle will not be cooled. The air inside the
vehicle will also not be dehumidified. The
windows can fog up more quickly. Therefore,
deactivate the cooling with air-
dehumidification function only briefly. Controlling front climate control
