Headlights 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.
Adjustment
Open the bonnet 3 164 and identify
the marking (shown in the illustration)
beside each of the headlights.
For each headlight:
Using a screwdriver, turn the screw
by a 1
/4 turn towards the
] symbol to
lower the beams or towards the <
symbol to raise the beams.
Ensure the headlight beams are
returned to their original positions
when required.
Daytime running lights
Daytime running lights increase
visibility of the vehicle during daylight.
They may be switched on
automatically when the engine is
running.
If required, the daytime running lights can be deactivated via the
Infotainment system. For further
information, refer to Infotainment
manual.

128Climate controlMaintenanceAir intake
The air intake in front of the
windscreen in the engine
compartment must be kept clear to
allow air intake. Remove any leaves,
dirt or snow.
Pollen filter
The pollen filter cleans dust, soot,
pollen and spores from the air
entering the vehicle through the air
intake.
Note
Pollen filter is only fitted to vehicles
with air conditioning system.
Air conditioning regular operation
In order to ensure continuously
efficient performance, cooling must
be operated for a few minutes once a month, irrespective of the weather
and time of year. Operation with
cooling is not possible when outside
temperature is too low.Service
For optimal cooling performance, it is recommended to annually check the
climate control system, starting
three years after initial vehicle
registration, including:
● functionality and pressure test
● heating functionality
● leakage check
● check of drive belts
● cleaning of condenser and evaporator drainage
● performance check
Note
Refrigerant R-134a contains
fluorinated greenhouse gases with a
global warming potential of 1430.
Front air conditioning system is filled with 0.58 kg and has a CO 2
equivalent of 0.83 tonnes, the front
and rear air conditioning system is filled with 0.88 kg and has a CO 2
equivalent of 1.26 tonnes.Depending on vehicle, information
regarding air conditioning refrigerant
appears on a label located in the
engine compartment.

Driver Information Centre 3 103).
Note
In the event the electronic key is kept in the front passenger compartment
and a message appears in the Driver
Information Centre (possibly
accompanied by a warning chime)
indicating that it is out of reception
range, we recommend inserting the
electronic key in the card reader.

inside the vehicle when children or animals are left in the vehicle, to
avoid unintended operation of
windows, doors or engine. Risk of
fatal injury.
Fault
If the engine cannot be started, the
cause may be one of the following:
● Fault in electronic key.
● Electronic key out of reception range.
● Battery voltage too low.
● Overload of the central locking system by operating at frequentintervals, the power supply is
interrupted for a short time.
● Interference from higher-power radio waves from other sources.
