WARNING
•
Always take the key with you when leaving the vehicle - even if
you only intend to be gone for a short time. This is especially
important if children are left in the car. They might otherwise be
able to start the engine or use power-operated equipment such as
the electric windows - this could lead to injuries. The window
switches are only deactivated when the driver's door or the front
passenger's door is opened.
•
Always be careful when closing the windows. Careless use of
the electric windows can cause severe injuries.
•
When locking the vehicle from the outside, make sure that
nobody is inside the vehicle, as the windows cannot be opened
from the inside in an emergency.Note
The windows can be operated for about ten minutes after the igni-
tion has been switched off. The window switches are only deacti-
vated when the driver's door or the front passenger's door is
opened.

WARNING
•
Take care when closing the windows and the sun roof*. Care-
less or uncontrolled use can cause injuries.
•
For safety reasons, you should only use the remote control
open and close functions within about 2 metres of the vehicle. To

The dipped beam headlights will only work with the ignition on.
The symbol
 next to the light switch will light up when the side
lights or headlights are on.Automatic headlight control (AUTO)*
When the switch is set to AUTO, the headlights switch on automati-
cally according to the ambient light conditions, for instance in a
tunnel, at sunset, or in the rain or snow. The
 symbol lights up
when the dipped headlights are on. The headlights are switched on,
regardless of the light conditions, when you switch on the fog
lights.
The headlights are switched off automatically when you switch off
the ignition.
On vehicles with a rain sensor, the headlights switch on automati-
cally after several windscreen wiper cycles. The instrument lighting
does not switch on, however.
While using the automatic headlights you can activate the main
beam headlights as normal if this function has been activated in the
MMI. However, if you switch on the main beam headlights while
using the AUTO function and then do not switch back to the dipped
headlights setting, only the dipped headlights will come on the next
time you switch on the AUTO function. To be able to use the main
beam headlights again you must first pull the main beam lever back
to the "off" position and then push it forward to "on".
Malfunction of light sensor
If a malfunction should occur in the light sensor, the instrument
cluster will show the message:
 Automatic headlights / automatic wipers defective
For safety reasons, the dipped beam headlights will then be
switched on permanently when the light switch is set to the AUTO
position. However, you can still switch the lights on and off in the
normal way with the light switch. You should have the light sensor
checked by a qualified workshop as soon as possible.
