Opening and clo sin g
Autom atic locking (Auto L ock )
The Auto Lock funct ion locks all doors and the
luggage compartment lid once the speed has ex­
ceeded approximately 9 mph (15 km/h).
The car is unlocked again once the ign ition key is
removed. In addition, the vehicle can be un locked
if the opening function in the power locking sys ­
tem switch is used or one of the door handles is
pu lled .
I n t he event of a crash with airbag deployment,
the doors automat ica lly unlock to allow access to
the v ehicle .
Anti-theft alarm system*
If t he anti- theft alarm system detects a vehicle
b reak-in, a udio and v isua l warning signals are
tr iggered.
The ant i-theft alarm system turns on automati­
cally when you lock the vehicle .
It deactivates

Lights and Vision
When switched on, adaptive light adjusts to
curves depending on the vehicle speed and steer­
ing wheel angle. This provides better lighting
through the curve. The system operates in a
speed range from approximately 6 mph (10 km/
h) to 68 mph (110 km/h) .
Static cornering light* -the cornering light
switches on automatically when the steering
wheel is turned at a ce rtain angle at speeds up to
approximately 44 mph (70 km/h) and when the
turn signal is activated at speeds up to approxi­
mately 25 mph (40 km/h) . The area to the side of
the vehicle is illuminated better when turning.
Speed dependent light distribution* -The speed
dependent light distribution adapts the light in
towns and on highways or expressways . Intersec­
tions can also be illuminated on vehicles with a
navigation system* .
Highway light function*
This function adapts the lighting for highway
driving based on vehicle speed .
A WARNING
-Automatic headlights* are only intended to
assist the driver. They do not relieve the
driver of responsibility to check the head­
lights and to turn them on manually accord­
ing to the current light and visibility condi­
tions. For example, fog cannot be detected by the light sensors . So always switch on the
low beam under these weather conditions
and when driving in the dark ~D.
- Accidents could occur if you can not see the road ahead of you well and if others on the
road cannot see you . Always switch your
headlights on so that you can see the road
ahead of you and others can see your vehicle
from behind.
- The rear fog lights should only be turned on
in accordance with traffic regulations, to
prevent glare for traffic behind your vehicle.
-If the battery has been discharging for a
while, the parking light may switch off auto­
matically. Always make sure your vehicle is
parked and adequately lit according to the
44
laws. Avoid using the parking lights for sev­
eral hours.
- Please observe legal regulations when using
the lighting systems described.
(D Tips
- The light sensor for the automatic head­
lights* is in the rearview mirror mount.
Therefore , do not place any stickers in this
area on the windshield.
- Some exterior lighting functions can be ad­
justed
Q page 45.
- If you turn off the ignition while the exterior lights are on and open the door, you will
hear a warning tone.
- In some market-specific versions, the tail
lights do not turn on when switching on the
daytime running lights .
- In cool or damp weather, the inside of the
headlights, turn signals and tail lights can
fog over due to the temperature difference between the inside and outside. They will
clear shortly after switching them on . This
does not affect the service life of the light­
ing.
-A message will appear in the instrument
cluster if there is a malfunction in the light
sensor
