General description
The power locking system locks or unlocks all
doors and the rear lid simultaneously.
You can lock and unlock the vehicle centrally.
You have the following choices:
- Remote master key~
page 30,
-Sensors in the front door handle on vehicles
with convenience key* ¢
page 31,
-Power locking switch ins ide¢ page 32,
oder
- Lock cylinder at the driver's door
~page 33.
Automatic locking
The automat ic locking feature locks all the ve­
hicle doors and the rear lid when you drive
faster than 9 mph (15 km/h).
The car is unlocked again once the ignition key
is removed. In addition, the veh icle can be un­
locked if the opening function in the power
locki ng system switch or at one of the door
levers is actuated.
Addit ionally, in the event of a crash with air­
bag deployment the doors are automatically
un locked to all ow access to the vehicle.
Selective unlocking
When you lock the vehicle, the power locking
system w ill lock the doors and the rear lid.
When unlocking, you can set in the rad io or
MMI* whether only the driver's door or the
enti re vehicle should be unlocked
¢page 32.
Anti-theft alarm warning system
If the anti -theft alarm warning system de­
tects a break- in into the vehicle, acoust ic and
visua l warning signals are triggered.
The anti-theft alarm system turns on auto­ matically when you lock the vehicle. It deacti ­
vates when unlocking using the remote con- trol key or by touching the sensor on the door
handle (convenience key) .
T o switch the alarm off, press the@ button on

sti ll switched on or the selector lever is not in
pos ition P.
Unintentionally locking yourself out
In the following cases there are safeguards to
prevent you from locking your remote master
key in the vehicle :
- The vehicle does not lock w ith the central
locking switch if the driver's door is open
~ page 32.
-On veh icles with convenience key*, if the
most recently used master key is in the lug­
gage compartment, the rear lid is automati ­
cally un locked again after it is closed.
Do not lock your veh icle w ith the remote mas­
ter key or convenience key* until all doors and
the rear lid are closed. In this way you avoid l ocking yourself out accidentally.
A WARNING
- When you leave the vehicle, always re­
move the ignition key and take it with

dren, for example) from accidentally be-
-
ing locked in the vehicle should they acci­
denta lly press the power locking switch

Headlight range control system
The headlight range adjusts automatically
when there is a change in veh icle load and
during braking and accelerating so that the
headlights do not cause glare for oncoming
traffic.
Adaptive light*
The adaptive light only functions when the
switch is in the AUTO position (Automatic
headlights). When switched on, adapt ive light
adapts to curves in the road depending on the
vehicle speed and the steering angle. This pro­
vides better lighting through the curve . The
system operates at speeds between approxi ­
mately 6 mph (10 km/h) and 68 mph
(110 km/h) .
_&. WARNING
- Daytime running lights and automatic
headlights* are only intended to assist
the driver. They do not relieve the driver
of his responsibility to check the head­
lights and to turn them on manually ac­
cording to the current light and visibility
conditions. For example, fog cannot be
detected by the light sensors*. So always
sw itch on the headlights
io under these
weather conditions and when driving in
the dark.
- Crashes can happen when you cannot see
the road ahead and when you cannot be
seen by other motorists. Always turn on
the headlights so that you can see ahead
and so that others can see your car from
the back.
- Please obey all laws when using the
lighting systems described here.
(D Note
The rear fog lights should only be turned
on in accordance with traffic regulation, as
-
the lights are bright for following traffic. .,._

(D Tips
-The light sensor* for headlight control is
located in the rear view mirror mount.
You should therefore not apply any stick­
ers to the windshield in this area in order
to prevent malfunctions or failures.

the vehicle's lights are turned on, a buz­
zer sounds as long as the driver's door is
open .

the headlights, turn signals and tail
lights can fog over due to the tempera­
ture difference between the inside and
outside. They will clear shortly after
switching them on. This does not affect
the service life of the lighting.
- In the event of a light sensor malfunc­
tion, the driver is notified in the instru­
ment cluster display~
