Lighting and visibility
Automatic illumination/
switching off of the headlamps
Automatic illumination
When the lighting control stalk ring is in
the AUTO position, the sidelamps and
dipped beam headlamps are switched on
automatically, without any action on the part of
the driver, when a low level of ambient light is
detected.
As soon as the level of light becomes sufficient
again, the lights are switched off automatically.
The sensor is located at the bottom of the
windscreen.
Do not cover the sunshine sensor, as the
associated functions would no longer be
controlled.
In fog or snow, the sunshine sensor may
detect sufficient light. The headlamps may
not come on automatically.
Automatic switching off
When the lighting control stalk is in the "AUTO"
position, if the ignition key is in the "LOCK" or
"ACC" position or is removed, the headlamps
will automatically switch off when the driver's
door is opened.

Wiper control stalk
The wipers are controlled directly by the driver
using control A and ring B.
In wintry conditions, remove snow, ice
or frost present on the windscreen,
around the wiper arms and blades and
the windscreen seal before operating the
wipers.
Do not operate the wipers on a dry
windscreen. Under extremely hot or cold
conditions, ensure that the wiper blades
are not stuck to the windscreen before
operating the wipers.
