Problem Possible causes/consequences and
M Solutions
The engine cannot be
started using the key. The on-board voltage is too low.
X
Switch off non-essential consumers, e.g. seat heating or interior
lighting, and try to start the engine again.
If this does not work:
X Check the starter battery and charge it if necessary
(Y page 290).
or
X Jump-start the vehicle (Y page 294).
or
X Consult a qualified specialist workshop. The engine cannot be
started using KEYLESS-
GO. The key is in the
vehicle. Ad
oor is open. Therefore, the key cannot be detected as easily.
X Close the door and try to start the vehicle again. There is interference from a powerful source of radio waves.
X Start your vehicle with the key in the ignition lock. Doors
Important safety notes
G
Risk of injury
Only for the United Kingdom: if the vehicle
has been locked with the key, the double lock
function is activated as standard. It is then not
possible to open the doors from inside the
vehicle.
Therefore, do not leave any people behind in
the vehicle, particularly children, elderly peo-
ple or people requiring special assistance, if
the vehicle has been locked with the key. As
a result, they may not be able to free them-
selves in the event of an emergency. They
could be seriously or even fatally injured by
prolonged exposure to extremely high or low
temperatures, for example. In this case, res-
cuing people from outside the vehicle is diffi-
cult.
Deactivate the interior motion sensor before
you lock the vehicle with the key. The doors
can then be opened from the inside after the vehicle has been locked from the outside with
the key.
If the vehicle has been locked with KEYLESS-
GO, the doors can be opened from inside the
vehicle.
G
Risk of accident
If children are left unsupervised in the vehicle,
they could:
R open a door from inside the vehicle at any
time, even if it has been locked
R start the vehicle using akey which has been
left in the vehicle
R release the parking brake
They could thereby endanger themselves and
others. Never leave children unsupervised in
the vehicle. Always take the key with you
when leaving the vehicle, even if you are only
leaving it for a short time. Doors

Adaptive Highbeam Assist G
Risk of accident
Adaptive Highbeam Assist is only an aid
designed to assist driving. The drive ris
responsible for adjusting the vehicle's lighting
to the prevailing light, visio nand traffic con-
ditions. The system may be impaired or deactivated:
R if there is poor visibility, e.g .due to snow,
rain, fog or spray
R if the area of the windscree naround the
optical sensor is dirty, misted up or covered
up, e.g. by a sticker
The system may not recognise the following
road users:
R road users that have no lighting, e.g. pedes-
trians
R road users that have poor lighting, e.g.
cyclists
R road users whose lighting is not clearly visi-
ble, e.g. road users behind a crash barrier
R on rare occasions: road users that have
lights that may be recognised too late or not
at all
The automatic main-bea mheadlamps will not
be deactivated, or they may be activated
despite road users travelling in fron tofor
approaching the vehicle.
Thus, you could cause an acciden tand injure
yoursel fand others. Alway sobserve traffic
conditions and, if necessary, dip the lights
manually.
You can use this function to set the head-
lamps to change between dipped beam and
main beam automatically. The system recog-
nises vehicles with their lights on, either
approaching from the opposite direction or
travelling in fron tofyour vehicle, and conse-
quently switches the headlamps from main
beam to dipped beam.
The system automatically adapts the dipped-
beam headlamp range depending on the dis-
tance to the other vehicle. Once the system
no longer detects any other vehicles, it reac-
tivates the main-beam headlamps.
The system's optical sensor is located behind
the windscreen near the overhead control
panel. 100

Risk of accident
Observe the settings recommended on the
following pages. Otherwise, the windows
could mist up. This may obstruct your view of
the traffic situation and, as a result, you may
cause an accident.
THERMATIC 2-zone automatic climate con-
trol/THERMOTRONIC luxury 3-zone auto-
matic climate control controls the tempera-
ture and the humidity of the vehicle interior
and filters out undesirable substances from
the air.
THERMATIC 2-zone automatic climate con-
trol/THERMOTRONIC luxury 3-zone auto-
matic climate control is only operational
when the engine is running 24
.O ptimum oper-
ation is only achieved if you drive with the side
windows and sliding sunroof/panorama slid-
ing sunroof closed.
i Ventilate the vehicle for a brief period
during warm weather, e.g. using the con-
venience opening feature (Y page 79). This
will speed up the cooling process and the
desired vehicle interior temperature will be
reached more quickly.
i The integrated filter can filter out most
particles of dust and completely filters out
pollen. Aclogged filter reduces the amount of air supplied to the vehicle interior
.For
this reason, you should always observe the
interval for replacing the filter, which is
specified in the Service Booklet .As it
depends on environmental conditions, e.g.
heavy air pollution, the interval may be
shorter than stated in the Service Booklet.

Important information The cooling with air dehumidification function
is only available when the engine is running.
The air inside the vehicle is cooled and dehu-
midified according to the temperature selec-
ted.
G
Risk of accident
If the "cooling with air dehumidification" func-
tion is deactivated, the air inside the vehicle
will not be cooled (during warm weather) or
dehumidified. The windows could mist up
more quickly. This may prevent you from
observing the traffic conditions, thereby caus-
ing an accident.
Condensatio nmay drip from the underside of
the vehicle when THERMOTRONIC is in cool-
ing mode. This is normal and no tasign that
there is a malfunction.
i The cooling with air dehumidification
function uses refrigerant R134a. This cool-
ant does not contain chlorofluorocarbons,
and therefore does not damage the ozone
layer. Activating/deactivating X
