Your car is equipped with a central locking system.
The central locking system allows you to lock and unlock all doors, the fuel fill-
er flap and boot lid at the same time.
Depending on the equipment configuration, the following is true after
unlocking
› The turn signal lights flash twice as confirmation that the vehicle has been
unlocked.
› The doors, the boot lid and the fuel filler flap are unlocked.
› The interior light operated via the door contact illuminates.
› The SafeLock system is switched off.
› The indicator light in the driver door stops flashing.
› The anti-theft alarm system is deactivated.
If you unlock the vehicle and do not open a door or the boot lid within the next
30 seconds, the vehicle will lock again automatically and the SafeLock system
or anti-theft alarm system will be switched on. This function is intended to
prevent the car being unlocked unintentionally.
Depending on the equipment configuration, the following is true after
locking
› The turn signal lights flash once as confirmation that the vehicle has been
locked.
› The doors, the boot lid and the fuel filler flap are locked.
›The interior light operated via the door contact goes out.
› The SafeLock system is switched on.
› The indicator light in the driver door begins flashing.
› The anti-theft alarm system is activated.
If the doors or the boot lid remain open after the vehicle has been locked, the
turn signal lights do not flash until they have been closed.WARNING■ Never leave the key in the vehicle when you exit the vehicle. Unauthor-
ized persons, such as children, for example, could lock the car, turn on the
ignition or start the engine - there is a danger of injury and accidents!■
When leaving the vehicle, never leave persons who are not completely in-
dependent, such as children, unattended in the vehicle. The children might,
for example, release the handbrake or take the vehicle out of gear. The ve-
hicle could then start to move – risk of injury and accidents! These individu-
als might also not be able to leave the vehicle on their own or to help
themselves. Can be fatal at very high or very low temperatures!
CAUTION
■ Each key contains electronic components; therefore it must be protected
against moisture and severe shocks.■
Keep the groove of the keys absolutely clean. Impurities (textile fibres, dust,
etc.) have a negative effect on the functionality of the locking cylinder and ig-
nition lock.
■
The battery must be replaced if the central locking or anti-theft alarm system
does react to the remote control at less than approx. 3 metres
away » page 210 .
■
When leaving the vehicle, always check if it is locked.
■
If the driver's door has been opened, the vehicle cannot be locked.
Note
In the event of an accident in which the airbags are deployed, the locked doors
are automatically unlocked in order to enable rescuers to gain access to the
vehicle.51Unlocking and opening

Fig. 47
Light switch: AUTO position
Read and observe on page 63 first.
If the light switch is in position
» Fig. 47 , the parking lights, low beam and
number plate lights are switched on or off automatically.
The light on / off switching is controlled by a sensor mounted under the wind- screen in the holder of the inside mirror or in the control panel.
If the light switch is in position
, the lettering
illuminates next to the

turned on » page 73, Windscreen wipers and washers .
The windscreen wipers are on for more than 15 s.
The light turns off about 4 minutes after turning off the wipers.
CAUTION
Do not attach any stickers or similar objects in front of the light sensor on the
windscreen to avoid impairing the function or its reliability.
Adaptive headlights (AFS)
Read and observe
on page 63 first.
The AFS system makes sure the street remains lit up depending on the traffic
and weather situation.
The AFS system automatically adjusts the cone of light in front of the vehicle
to the driving speed or the use of the wiper.
The AFS system works as long as the light switch is in position
» page 66 .
The AHL system operates in the following modes.
Out of town mode
The cone of light in front of the vehicle is similar to the low beam.
City mode
The light cone in front of the vehicle is adjusted so that it illuminates this and
the adjacent sidewalks, intersections, pedestrian crossings, etc. The mode is
active at speeds of 15-50 km / h.
Motorway mode
The cone of light in front of the vehicle is adjusted so that the driver can re-
spond in time to an obstruction or other hazard in time. The mode is active at
speeds above 120 km/h.
Rain mode
The cone of light in front of the vehicle is adjusted so that the driver can re-
duce the glare from oncoming vehicles in rain.
66Using the system

The mode is active when the wipers operate continuously for longer than 2 mi-
nutes at a speed of 20 - 70 km / h. The mode is deactivated when the wind-
screen wipers are switched off for longer than 8 minutes.
Dynamic cornering lights
The cone of light in front of the vehicle is adjusted to the steering angle so
that the road in the curve is illuminated. This function is active at speeds
greater than 10 km.h and in all AFS modes.
Tourist lights (Travel mode)
This mode makes it possible to drive in countries with opposing traffic system
(driving on the left/right) without dazzling the oncoming vehicles.
When this mode is active, the above-mentioned modes and the side swivel of
the headlights is deactivated.
This mode can be enabled or disabled via the MAXI DOT display in the Travel
mode » page 47 , Settings menu option.WARNINGIf the AFS system is defective, the headlights are automatically lowered to
the emergency position, which prevents a possible dazzling of oncoming
traffic. This reduces the cone of light in front of the vehicle. Drive carefully
and visit a specialist garage as soon as possible.
Note
When the “tourist light” mode is active, the warning light flashes for 10 sec-
onds each time the ignition is switched on.
