WARNING
The electrically adjustable steering wheel can
still be adjusted when there is no key in the
ignition lock. Therefore, do not leave children
unsupervised in the vehicle, as they could
become trapped if the steering wheel is adjus-
ted. G
WARNING
Only adjust the steering wheel when the vehi-
cle is stationary and do not pull away until the
steering wheel adjustment mechanism is
locked in position. You might otherwise drive
without the steering wheel adjustment mech-
anism being locked in position. As aresult,

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 windscreen around the
optical sensor is dirty, misted up or covered
up, e.g. by asticker
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 acrash barrier
R on rare occasions :road users that have
lights that may be recognised too late or not
at all
The automatic main-beam headlamps will not
be deactivated, or they may be activated
despite road users travelling in front of or
approaching the vehicle.
Thus, you could cause an accident and injure
yourself and others. Always observe traffic
conditions and, if necessary, dip the lights
manually. Headlamps misted up inside
The headlamps may mist up on the inside if
there is high atmospheric humidity.
X Drive with the headlamps switched on.
The level of moisture diminishes, depend-
ing on the length of the journey and the
weather conditions (humidity and temper-
ature).
If the level of moisture does not diminish:

It is possible to make use of the residual heat
of the engine to continue heating the station-
ary vehicle for up to 30 minutes after the
engine has been switched off. The heating
time depends on the temperature that has
been set.
Coupé: the residual heat function only works
optimally when the side window sand pano-
rama sliding sunroo fare closed.
Cabriolet: the residualh eatfunction only
work soptimally when th esoftt op is closed.
i The blower will run at alow speed regard-
less of the airflow setting.
i If you activate the residual heat function
at high temperatures, only the ventilation
will be activated. The blower runs at
medium speed.
i It is possible that the residual heat func-
tion may be activated automatically an hour
after the key is removed. The vehicle is then
ventilated for 30 minutes to dry the air-
conditioning system.

Important safety notes G
WARNING
Exhaust fumes are produced when the auxili-
ary heating is in operation. Inhaling these
exhaust fumes can be poisonous. You should
therefor eswitch off the auxiliary heating in
confined spaces without an extraction sys-
tem, e.g. agarage. G
WARNING
When operating the auxiliary heating, parts of
the vehicle may become very hot, and highly
inflammable material such as fuels could be
ignited. Operating the auxiliary heating is thus
prohibited at filling station sorwhen your vehi-
cle is being refuelled. You must therefore
switch off the auxiliary heating at filling sta-
tions.
! Operating the auxiliary heating/ventila-
tion draws on the vehicle battery. After you
have heated or ventilated the vehicle a
maximum of two times, drive for alonger
distance.
i Switch on the auxiliary heating regularly,
e.g. for about ten minutes every month.
The auxiliary heating heats the air in the vehi-
cle interior to the set temperature without
using the heat of the running engine. The aux-
iliary heating is operated directly using the
vehicle's fuel. For this reason, the tank con-
tent must be at least at reserve fuel level to
ensure that the auxiliary heating functions.
The auxiliary heating/ventilation automati-
cally adjusts to changes in temperature and
weather conditions. For this reason, the aux-
iliary heating could switch from ventilation
mode to heating mode or from heating mode
to ventilation mode.
The auxiliary heating switches off automati-
cally after 50 minutes. This time limit can be
altered. To do this, visit aqualified specialist
workshop, e.g. aMercedes-BenzS ervice
Centre. Operating thec

You cannot use the auxiliary ventilation to
cool the vehicle interior to atemperature
lower than the outsid etemperature.
Befor eswitchin gon X

The auxiliary heating/ventilation can be acti-
vated even when the climat econtrol is being

be attained when the system is set to auto-
matic mode. Set the temperature to 22 †.
The auxiliary heating/ventilation can be acti-
vated or deactivate dusing the remote control
or the button on the centr econsole.

ify up to three departure times, one of which
may be preselected (Y page 229).

econtrol.
You may use two additional remot econtrols
for your vehicle. For further information, con-
sult aqualified specialist workshop ,e.g.a
Mercedes-Ben zService Centre.
The remote control has amaximum range of
approximately 300 metres. This range is
reduced by:
R sources of radio interference
R solid objectsb etween the remote control
and the vehicle
R the remote control being in an unfavoura-
ble position in relation to the vehicle
R transmitting from an enclosed space
