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

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.
- Applies to vehicles with power side door
closer*:
- When closing a door, make sure noth­
ing can interfere with the door. This
could cause serious personal injury.
- You can stop the door from closing at

function, you can lock the driver's door
using the mechanical key¢
page 36.
- If
the power locking system should fail,
you can still open the fuel tank flap in an
emergency¢
page 231.
-You are well advised not to keep valua­
bles inside an unattended vehicle, visible
or not. Even a properly locked vehicle
cannot provide the security of a safe.
- If the LED in the upper edge of the driv­
er's door panel comes on for about 30
seconds after the vehicle is locked, there
is a malfunction in the power locking or
the anti-theft warning system. Have the malfunction corrected by an authorized

46 Clear vision
Highway light function* (vehicles with LED
headlights) -this function adapts the lighting
for highway driving based on vehicle speed.
.&_ 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 §.0
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 observe legal regulations when
using the lighting systems described.
(D Note
The rear fog lights should only be turned
on in accordance with traffic regulation, as
the lights are bright for following traffic.
@ Tips
- The light sensor* for automatic dynamic
headlight range control* is located in the
rear view mirror mount. You should
therefore not apply any stickers to the
windshield in this area in order to pre­
vent malfunctions or failures .
- In the event of a light sensor malfunc­
tion, the driver is notified in the instru­
ment cluster display¢
page 22 .
- 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 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.
Emergency flasher
The emergency flasher makes other motorists
