2010 MERCEDES-BENZ CLS COUPE heating

Problems with the steering wheel heat-
ing
If the steering wheel heating indicator lamp
on the lower left lever of the steering column
is flashing, the steering wheel heating has
switched off automatically. The vehicle's
electrical system voltage is too low because
too many electrical consumers are switched
on.
X
Switch off electrical consumers which you
do not need, such as the rear window heat-
ing or interior lighting.
Once the battery is sufficiently charged, the
steering wheel heating will switch back on
automatically. EASY-ENTRY/EXIT system
G
Risk of injury
Make sure that nobody can become trapped
when you activate the EASY-ENTRY/EXIT fea-
ture.
If there is a risk of someone becoming trap-
ped, stop the adjustment procedure. To halt
the procedure:
R move the switch for steering wheel adjust-
ment in the opposite direction to that in
which the steering wheel is moving.
R press one of the memory function position
buttons.
Never leave children unsupervised in the vehi-
cle. They could open the driver's door and
thereby unintentionally activate the EASY-
ENTRY/EXIT feature and become trapped.
The EASY-ENTRY/EXIT feature makes getting
in and out of your vehicle easier.
The steering wheel swings upwards when
you:
R remove the key from the ignition lock
R open the driver's door and KEYLESS-GO is
in position 1
R open the driver's door and the key is in
position 0or 1in the ignition lock i
The steering wheel only moves upwards if
it has not already reached the upper end
stop.
If you insert the key into the ignition lock with
the driver's door closed, the steering wheel is
automatically moved to the previously set
position.
The last position of the steering wheel is
stored after each manual setting or when you
store the setting with the memory function
(Y page 95).
You can activate and deactivate the EASY-
ENTRY/EXIT feature in the on-board com-
puter (Y page 211).
i If the crash-responsive EASY-EXIT feature
is triggered in an accident, the steering col-
umn will move upwards when the driver's
door is opened. This occurs irrespective of
the position of the key in the ignition lock.
This makes it easier to exit the vehicle and
rescue the occupants.
The crash-responsive EASY-EXIT feature is
only operational after an accident if the
EASY-EXIT/ENTRY feature is activated in
the on-board computer. Mirrors

Important safety notes G
Risk of poisoning
Exhaust fumes are produced when the auxili-
ary heating is in operation. Inhaling these
exhaust fumes can be poisonous. You should
therefore switch off the auxiliary heating in
confined spaces without an extraction sys-
tem, e.g. a garage. G
Risk of fire
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 a longer
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 a qualified specialist
workshop, e.g. a Mercedes-Ben
zService
Centre.
You cannot use the auxiliary ventilation to
cool the vehicle interior to a temperature
lower than the outside temperature.
Before switching on X
Turn the key to position 2in the ignition
lock.
X Set the temperature.
The auxiliary heating/ventilation can be acti-
vated even when the climate control is being
controlled manually. Optimum comfort can
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 deactivated using the remote control
or the button on the centre console.
The on-board computer can be used to spec-
ify up to three departure times, one of which
may be preselected (Y page 210). Operating the climate control system

Switching the auxiliary heating/venti-
lation on/off using the remote control Your vehicle comes with one remote control.
You may use two additional remote controls
for your vehicle. For further information, con-
sult a qualified specialist workshop, e.g. a
Mercedes-Benz Service Centre. The remote control has a maximum range of
approximately 300 metres. This range is
reduced by:
R
sources of radio interference
R solid objects between 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
i The optimum range can be achieved if you
hold the remote control vertically, pointing
upwards when you press one of the but-
tons.
