Technical data door is unlocked. The remote control key has to be within a range of
about 1.5 metres of the relevant door or the boot lid. It does not
matter where you carry the key, for instance whether it is in your
jacket pocket or in a briefcase.
The unlocking function may be affected if the sensor area on the
door handle is touched while the vehicle is being unlocked.
The locking function may be affected if you grasp the door handle
while the vehicle is being locked.
Once the doors have been locked, they cannot be opened again
immediately. This will enable you to check that the doors are prop-
erly closed.
The system will either unlock both the doors or one door only,
depending on the settings you have chosen on the sound system or
MMI* ⇒page 43.
WARNING
Do not leave anyone (especially children) in the car if it is locked
from the outside and the deadlock mechanism is activated: the
doors and windows cannot then be opened from the inside.
Locked doors could delay assistance in an emergency, potentially
putting lives at risk.
Note
Please note the following points if the vehicle is left parked for long
periods:•
To save electrical power, the proximity sensors are switched off
after a few days. You will then need to pull the door handle once to
unlock the vehicle, and a second time to open it.
•
To prevent the battery from becoming discharged and thus
maintain the vehicle's starting ability for as long as possible, the
power management system will gradually switch off convenience
functions that are not required. In this case you may not be able to
unlock the vehicle with this convenience function.
Locking and unlocking the vehicle using the key

still lock and unlock the driver's door by turning the emer-
gency key or spare key in the lock.Unlocking

– If you turn the key to position a second time within 2
seconds, this will lock the vehicle without activating the
deadlock mechanism.In order to switch off the anti-theft alarm*, you must switch on the
ignition within 15 seconds after opening the driver's door. Other-
wise the alarm will be triggered.

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.
