To deactivate, operate the same
procedure as described above.
Control indicator f will not flash when
function is deactivated.
Daytime running lights
Daytime running lights increase
visibility of the vehicle during daylight.
They are switched on automatically
when ignition is on.
If the vehicle is equipped with
automatic light control function, the
system switches between daytime
running light and low/high beam
automatically, depending on the
lighting conditions and information
given by the rain sensor system.

Adaptive forward lighting
The Adaptive forward lighting
functions are only available with Bi-
Xenon headlights. Light range, light
distribution and intensity of light are
variably triggered depending on the
light conditions, weather and road
type.With the light switch in position
AUTO all lighting functions are
available.
The following functions are available
also with light switch in position 9:
■ Dynamic curve lighting
■ Cornering light

up to approx. 30 km/h. The light beam is turned at an angle of 8° to the
roadside.
Town lighting Activated automatically at a speed
range between approx. 40 and
55 km/h and when street lights are
detected by the light sensor. The light
range is reduced by an extended light
distribution.Country lighting
Activated automatically at a speed
range between approx. 55 and
115 km/h. The beam of light and the
brightness is different between the left and the right side.

above approx. 115 km/h and minimal
steering movements. It switches on
after a delay or directly when the
vehicle is powerfully accelerated. The
light beam is longer and brighter.
Adverse weather lighting Activated automatically up to a speed
of approx. 70 km/h, when the rain
sensor recognizes condensation or
the wiper operates continuously. The

Press button n to switch on cooling.
Activation is indicated by illumination
of 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) when outside
temperature is above a specific level. 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. When the cooling
system is switched off, no engine restart will be requested by the
climate control system during an
Autostop. Exception: defrost system
is activated and outside temperature
above 0° C requests a restart.
The display will indicate ACON when
cooling is activated or ACOFF when
the cooling is deactivated.Activation or deactivation of cooling
operation after engine start can be
changed in the Settings menu in the
Info-Display. Vehicle personalisation

Air recirculation mode 4
Press button 4 to activate air
recirculation mode. Activation is
indicated by illumination of the LED in
the button.
Press button 4 again to deactivate
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 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 may mist
up from outside, when cold air is
directed towards it. If windscreen
mists up from outside, activate
windscreen wiper and deactivate s.

Climate control131Auxiliary heater
Air heater Quickheat is an electric auxiliary airheater which automatically warms up
the passenger compartment more
quickly.Air vents
Adjustable air vents At least one air vent must be open
while the cooling is on.
To open the vent, turn the adjuster
wheel towards the bigger W symbol.
Adjust the air amount at the vent
outlet by turning the adjuster wheel.
Direct the flow of air by tilting and
swivelling the slats.
To close the vent, turn the adjuster
wheel towards the smaller W symbol.
9 Warning
Do not attach any objects to the
slats of the air vents. Risk of
damage and injury in case of an
accident.
Fixed air vents
Additional air vents are located
beneath the windscreen and door windows and in the foot wells.
Driving and operating139key. Turn the front wheels
towards the kerb.
■ Close the windows and the soft top.
■ Remove the ignition key. Turn the steering wheel until the
steering wheel lock is felt to
engage.
For vehicles with automatic
transmission, the key can only
be removed when the selector
lever is in position P.
■ Lock the vehicle.
■ Activate the anti-theft alarm system.
Note
In the event of an accident with airbag deployment, the engine is
turned off automatically if the vehicle
comes to a standstill within a certain time.
Engine exhaust9 Danger
Engine exhaust gases contain
poisonous carbon monoxide,
which is colourless and odourless and could be fatal if inhaled.
If exhaust gases enter the interior
of the vehicle, open the windows.
Have the cause of the fault
rectified by a workshop.
Avoid driving with an open load
compartment, otherwise exhaust
gases could enter the vehicle.
Diesel particle filter
The diesel particle filter system filters
harmful soot particles out of the
exhaust gases. The system includes
a self-cleaning function that runs
automatically during driving without
any notification. The filter is cleaned
by periodically burning off the soot
particles at high temperature. This
process takes place automatically
under set driving conditions and may
take up to 25 minutes. Typically it
needs between 7 and 12 minutes. Autostop is not available and fuel
consumption may be higher during
this period. The emission of smells and smoke during this process is
normal.
Under certain driving conditions, e.g.
short distances, the system cannot
clean itself automatically.
If the cleaning of the filter is required
and if previous driving conditions did
not enable automatic cleaning, it will
be indicated by control indicator %.
140Driving and operating
Simultaneously Diesel partic. filter is
full continue driving appears in the
Driver Information Centre.
% illuminates when diesel particle
filter is full. Start cleaning process as
soon as possible.
% flashes when diesel particle filter
has reached the maximum filling level. Start cleaning process
immediately to avoid damage to the
engine.
Cleaning process
To activate cleaning process,
continue driving, keep engine speed
above 2000 revolutions per minute.
Shift down if necessary. Diesel
particle filter cleaning is then started.
If additionally a message appears in
the Driver Information Centre that
cleaning is not possible, seek the
assistance of a workshop.Caution
If the cleaning process is
interrupted, there is a risk of
provoking severe engine damage.
Cleaning takes place quickest at high engine speeds and loads.
The control indicator % extinguishes
as soon as the self-cleaning
operation is complete.
Catalytic converter
The catalytic converter reduces the
amount of harmful substances in the
exhaust gases.Caution
Fuel grades other than those listed on pages 3 172, 3 234 could
damage the catalytic converter or
electronic components.
Unburnt petrol will overheat and
damage the catalytic converter.
Therefore avoid excessive use of the starter, running the fuel tank
dry and starting the engine by
pushing or towing.
In the event of misfiring, uneven
engine running, a reduction in engine performance or other unusual
problems, have the cause of the fault
rectified by a workshop as soon as
possible. In an emergency, driving
can be continued for a short period,
keeping vehicle speed and engine
speed low.
