when the ignition is switched on.
If the vehicle is equipped with the
automatic light control function, the
system switches between daytime running lights and headlights
automatically depending on the
lighting conditions. Automatic light

Adaptive forward lighting
Cornering light
Depending on the steering angle,
vehicle speed and gear selected
when cornering, an additional light
will illuminate the corner of the road
on the respective side when the
headlights are switched on.
The cornering light is switched off
automatically after prolonged use and at vehicle speeds above 40 km/h.Hazard warning flashers
Operated by pressing ¨.
In the event of hard braking, the
hazard warning flashers may turn on automatically. Switch off by pressing

When the steering wheel is turned
back, the lever automatically returns
to its original position and the
indicator is deactivated. This will not happen when making a minor
steering manoeuvre such as lane
changing.
For three flashes, e.g. when changing lanes, move lever part way to first
stop. When released, lever will spring
back.

control to J.
Air conditioning system
Additional to the heating and
ventilation system, the air
conditioning system has controls for:
A/C:coolingu:air recirculationHeated rear window Ü 3 41, Heated
seats ß 3 50.
Cooling (A/C)
Press A/C to switch on cooling. The
LED in the button illuminates to
indicate activation. Cooling is only
functional when the engine is running
and climate control fan is switched on.
Press A/C again to switch off cooling.
The air conditioning system cools and
dehumidifies (dries) the air when
outside temperature is a little above
the freezing point. Therefore
condensation may form and drip from under the vehicle.
If no cooling or drying is required,
switch the cooling system off to save
fuel.
Note
If the climate control is set to
maximum cooling while the ambient temperature is high, an Autostop
may be inhibited until the required
temperature in the passenger
compartment has been reached.If the climate control is set to
maximum cooling while the engine is
in an Autostop, the engine may
restart automatically.
Stop-start system 3 136.
Air recirculation system Press u to activate air recirculation
mode. The LED in the button
illuminates to indicate activation.
Press u again to deactivate air
recirculation mode.9 Warning
The exchange of fresh air is
reduced in air recirculation mode.
In operation without cooling the air humidity increases, so the
windows may mist up. The quality
of the passenger compartment air
deteriorates, which may cause the vehicle occupants to feel drowsy.
Maximum cooling
Briefly open the windows so that hotair can disperse quickly.

If no cooling or drying is required,
press A/C OFF to switch the cooling
system off, thus saving fuel.

Rear heating system
If the engine is switched off, the rear
compartment can be heated by the
additional heating, through low level
vents.
By programming values using the
control panel, the user can adjust the
time, day and temperature settings.
Heating will cease to operate if the
vehicle fuel level drops too low.
During operation, power from the
vehicle battery is used. For short
journey times, check the vehicle
battery regularly and recharge if
necessary.
Note
If the rear heating system is
activated while the engine is
running, an Autostop will be
inhibited.
To ensure efficient performance, the
low level air vents in the rear
passenger compartment must not be
obstructed.

Climate control1219Warning
Do not operate the system when
refuelling, when dust or
combustible vapours are present
or in enclosed spaces (e.g.
garage).

Note
Rear air conditioning cannot be
switched on during an Autostop.
Stop-start system 3 136.
Combi
Additional air conditioning is supplied to the rear passenger compartment
via the air vents located above the
driver and front passenger
compartment.
With the front passenger
compartment air conditioning system
switched on, adjust the air flow to
select the desired speed.
Ensure the air vents are open when in
use, to prevent ice forming in the
system due to lack of air movement.
Auxiliary heaterCoolant heater
The engine-independent, fuel-
powered coolant heater provides
rapid heating of the engine coolant to
enable heating of the vehicle interior
without the engine running.
Note
Depending on version, an additional
coolant heater may be switched on
automatically to speed up heating
when the ignition is on and the
outside temperature is below 5 ℃.9 Warning
Do not operate the system when
refuelling, when dust or
combustible vapours are present
or in enclosed spaces (e.g.
garage).
Before starting or programming the
system to start, turn the vehicle's
climate control system to heat, set the
air distribution to V and turn the fan
on.
Switch off when not required. Heating stops automatically after the
programmed runtime. It will also
cease to operate if the vehicle fuel
level drops too low.
During operation, power from the
vehicle battery is used. The driving
time should therefore be at least as
long as the heating time. For short
journey times, check the vehicle
battery regularly and recharge if
necessary.
To ensure efficient performance,
briefly operate the auxiliary heater
once a month.

Climate control125configures the remote control menu

be reduced due to environmental
conditions and as the battery
becomes weaker.

If the remote has not been used for a long period, press the OFF button six
times at intervals of two seconds,
then press and hold for another
two seconds, then wait two minutes.

Climate control129Air vents
Adjustable air vents At least one air vent must be open
while cooling is on in order to prevent
the evaporator from icing up due to
lack of air movement.
Centre air vents
Press the vent to open.
Direct the flow of air by swivelling the vent.
Push vent to close.
Side air vents
Press the vent to open.
Direct the flow of air by swivelling the vent.
Depending upon the position of the
temperature control, air will be
directed into the vehicle via the side
air vents.
9 Warning
Do not attach any objects to the
slats of the air vents. Risk of
damage and injury in the event of
an accident.
Combi
Adjustable air vents may be located in the roof frame. To open, press air
vent. Hold air vent and turn it to the
required position to direct the airflow.
