Automatic light control functionWhen the automatic light control
function is switched on and the
engine is running, the system
switches between daytime running
light and low beam depending on
external lighting conditions.
Daytime running light
Daytime running light increases
visibility of the vehicle during daylight.
Tail lights are not on.
Automatic low beam activation
During poor lighting conditions the
low beam is switched on.
Tunnel detection
When a tunnel is entered the low
beam is switched on.
Adaptive forward lighting 3 100.High beam
To switch from low to high beam,
push lever.
To switch to low beam, push lever
again or pull.

100LightingHeadlights when driving
abroad The asymmetrical headlight beam
extends visibility at the edge of the
road at the passenger side.
However, when driving in countries
where traffic drives on the opposite
side of the road, adjust the headlights
to prevent dazzling of oncoming
traffic.
Vehicles with halogen headlight system Have the headlights adjusted by aworkshop.
Vehicles with adaptive forward lighting
Adapting the aim of the headlight beam:
1. Pull headlight flash lever.
2. Switch on ignition.
3. Hold headlight flash lever. After approx. 5 seconds the control
indicator B starts flashing and an
acoustic signal sounds.Control indicator B 3 85.
Every time the ignition is switched on,
B illuminates for approx. 8 seconds.
For deactivation, operate the same
procedure as described above.
Control indicator B will illuminate for
approx. 4 seconds when the function is deactivated.
Adaptive forward lighting
Adaptive forward lighting ensures
better illumination of bends, crossings
and narrow bends.
Dynamic curve lighting
The light beam pivots based on
steering wheel angle and speed,
improving lighting in curves.
Corner lighting
On tight bends or when turning off,
depending on the steering angle or
the indicator light signal, an additional left or right reflector is switched on
which illuminates the road in the
direction of travel. It is activated up to
a speed of 25 mph.
Reversing function If the lights are on, reverse gear is
engaged, and the turn signal is
activated, the cornering light on the
appropriate side is switched on. The cornering light stays on for
15 seconds once the turn signal has
been switched off.
Control indicator B 3 85.

The lever always springs back to its
original position.
If the lever is moved past the
resistance point, the turn signal is
switched on constantly. When the
steering wheel moves back, the turn
signal is automatically deactivated.
For three flashes, e.g. when changing lanes, press the lever until resistance
is felt and then release. This function
can be activated or deactivated
depending on the key used 3 95.
Move the lever to the resistance point
and hold for longer indication.
Switch the turn signal off manually by moving the lever slightly.
Acoustic turn signal The volume of the acoustic turn signal
can be adjusted. This function can be programmed depending on the key
used 3 95.

■Open side air vents as required and
direct them towards door windows.
■ For simultaneous warming of the foot well, set air distribution control
to J.
Notice
If the settings for demisting and
defrosting are selected, an Autostop
will be inhibited.
If the settings for demisting and

Stop-start system 3 116.Air conditioning system
In addition to the heating and
ventilation system, the air
conditioning system has:
n=cooling4=air recirculation
Heated seats ß 3 38, Heated
steering wheel * 3 71.
Cooling n
Press button n to switch on cooling.
Activation is indicated by the LED in
the button. Cooling is only functional
when the engine is running and
climate control fan is switched on.
Press button n again to switch off
cooling.
The air conditioning system cools and
dehumidifies (dries) as soon as the
outside temperature is slightly above
the freezing point. Therefore
condensation may form and drip from
under the vehicle.
If no cooling or drying is required,
switch off the cooling system for fuel
saving reasons. Activated cooling
might inhibit Autostops.
Notice
If the climate control is set to
maximal cooling while the ambient
temperature is high, an Autostop
may be inhibited until the requested
temperature in the passenger
compartment has been reached.
If the climate control is set to
maximal cooling while the engine is
in an Autostop, the engine may
restart automatically.

112Climate control9Warning
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 from inside.
The quality of the passenger
compartment air deteriorates,
which may cause the vehicle
occupants to feel drowsy.
In warm and very humid ambient air conditions, the windscreen might mist up from outside, when cold air is
directed to it. If windscreen mists up
from outside, activate windscreen
wiper and deactivate s.
Auxiliary heater Air heater
Quickheat is an electric auxiliary air
heater which automatically warms up
the passenger compartment more
quickly.
Coolant heater
Diesel-engined vehicles have a fuel-
powered auxiliary heater.Air 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.
Set the direction of the air flow by
turning the adjuster wheel from right to left and raise or lower the horizontal slats.
