- Remote master key¢
page 34,
- Door handles with convenience key*
¢page 35 ,
- Lock cylinder at the driver's door
¢page 36, or
- Power locking switch inside¢
page 36.

When you lock the vehicle, the power locking
system will lock the doors and the rear lid.
When unlocking, you can set in the MMI
whether only the driver's door or the entire
vehicle should be unlocked
¢page 34.

The automatic locking feature locks all the ve­
hicle doors and the rear lid when you drive
faster than 9 mph (1S km/h).
T he car is unlocked again, when the opening
function in the power locking system switch
or at one of the door levers is actuated .
Anti-theft alarm warning system
If the anti-theft alarm warning system de­
tects a break-in into the vehicle, acoustic and
visual warning signals are triggered .
T he anti-theft warning system is activated au­
tomatically when you lock the vehicle . It is de­
activated when unlocking using the remote key, with the mechanical key, and when you
switch the ignition on.
The alarm also turns off when the alarm cycle has expired .
Opening and closing 33

one of the doors, the rear lid or the hood is not locked.
Unintentionally locking yourself out
In the following cases there safeguards to
prevent you locking your remote master key in
the vehicle:
- The vehicle does not lock with the central
locking switch¢
page 36 if the driver's
door is open.
- On vehicles with convenience key*, if the
most recently used master key is in the lug­
gage compartment, the rear lid is automati­
cally unlocked again after it is closed.
Do not lock your vehicle with the
remote mas­
ter key or convenience key*
until all doors
and the rear lid are closed. In this way you
avoid locking yourself out accidentally.

¢..1, .
A WARNING
-
- When you lock your vehicle from outside,
nobody -especially children -should re­
main inside the vehicle. Remember,
when you lock the vehicle from the out­
side the windows cannot be opened from
the inside.
- When you leave the vehicle, always take
the ignition key with you . This will pre­
vent passengers (children, for example) from accidentally being locked in the ve­
hicle should they accidentally press the
power locking switch in the doors.
- Do not leave children inside the vehicle
unsupervised. In an emergency it would
be impossible to open the doors from
the outside without the key.

44 Clear vision
& WARNING
- Automatic headlights are only intended
to assist the driver . They do not relieve
the driver of his responsibility to check
the headlights and to turn them on man­
ually according to the current light and
visibility conditions. For example, fog
cannot be detected by the light sensors.
So always switch 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
theheadlightssothatyoucanseeahead and so that others can see your car from
the back .
- The rear fog lights should only be turned
on in accordance with traffic regulation,
as the lights are bright for following traf­
fic.
- Please observe legal regulations when using the lighting systems described .
@ Tips
-The light sensor* for automatic head­
light range control* is located in the rear
view mirror mount . You should therefore
not apply any st ickers to the windshield
in this area in order to prevent malfunc­
tions or failures.
- In the event of a light sensor malfunc­
tion, the driver is notified in the instru­
ment cluster display
Q page 2 3 .
-You will hear a warning tone if you open
the driver door when the exterior lights
are switched on.
- In cool or damp weather, the inside of
the headlights, turn signa ls 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.

.&_ WARNING
-
-The rain sensor is only designed to assist
and support the driver.
It remains entire­
ly t he driver's responsibility to monitor
outside weather cond itions and to man­
ually activate the wipe rs as soon as rain
or drizzle reduces v isibility through the
windshie ld.
- The windsh ield must no t be treated w ith
wate r-repellent mate rials. They can in­
crease glare unde r poo r vis ibility condi ­
tions such as we tness, d arkness, or when
the s un is low on the hor izon. In addi­
tion, they can cause the w indshield w ip­
ers to chatter .
- Prope rly f unctioning windshield wiper
b lades are required for a clear view and
safe driving
q page 49, Replacing
windshield wiper blades.
(D Note
- In the case of frost, check whethe r th e
windshield wiper blades are frozen to
the windsh ield. Sw itching on the wind­
shield wipers can damage the wiper
blades!
- Prior to us ing a car wash, the w indshield
w iper system must be sw itched off (lever
in posit ion @). Th is he lps to prevent un­
intentional switching on and damage to
the winds hield wiper system.
- Do not use the w ipers to clear a frosted
w indow. Us ing the wipers as a conven­
ient ice scrape r will destroy the wipe r
blades .
(D Tips
-The windshie ld w ipers are switched off
w hen the ignit ion is off . Activate the
w indshield wipers after the ign ition is
s witched back o n by moving the w ind­
shield wiper lever to any position.
- Worn or dirty windshield wipe r blade s
result in streaking. This can affec t the
