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 3 168 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.

Cornering lights
With the low beam switched on,
depending on the steering angle, vehicle speed and gear selected
when cornering, the front fog light will also switch on, to illuminate the
corner of the road on the respective
side.
