Important safety notes G
DANGER
If the exhaust pipe is blocked or sufficient
ventilation is not possible, toxic exhaust
fumes can enter the vehicle, especially car- bon monoxide. This is the case, e.g. in
enclosed spaces, or if the vehicle is stuck in
snow. There is a risk of fatal injuries.
You should switch off the auxiliary heating in
enclosed spaces which do not have an extrac- tion system, e.g. a garage. If the vehicle is
stuck in snow and you must leave the auxiliary
heating running, keep the exhaust pipe and
the area around the vehicle clear of snow. To guarantee a sufficient supply of fresh air, open
a window on the side of the vehicle away from the wind. G
WARNING
When the auxiliary heating is switched on,
parts of the vehicle can become very hot.
Flammable materials such as leaves, grass or twigs may ignite if they come into contact
with:
R hot parts of the exhaust system
R the exhaust gas itself
There is a risk of fire.
When the auxiliary heating is switched on,
make sure that:
R no flammable materials come into contact
with hot vehicle components
R the exhaust gas can escape from the
exhaust pipe unhindered
R the exhaust gas does not come into contact
with flammable materials.
The auxiliary heating and the exhaust gas outlet are situated in front of the right-hand front
wheel.
! Operating the auxiliary heating/ventilation
draws on the vehicle battery. After you have
heated or ventilated the vehicle a maximum of two times, drive for a longer distance.
Switch the auxiliary heating on regularly once a
month for about ten minutes.
The auxiliary heating timer function calculates
the switch-on time according to the outside
temperature so that the vehicle is preheated by the departure time. When the departure time isreached, the auxiliary heating continues to heat
for a further five minutes and then switches off. 126
Operating the climate control systemClimate control
Page 130 of 345
The auxiliary heating heats the air in the vehicle
interior to the set temperature. This occurs with- out using the heat of the running engine. The
auxiliary heating is operated directly using the
vehicle's fuel. For this reason, the fuel tank must
be at least Õfull to ensure that the auxiliary
heating functions.
The auxiliary heating/ventilation automatically
adjusts to changes in temperature and weather conditions. For this reason, the auxiliary heating could switch from ventilation mode to heating
mode or from heating mode to ventilation mode.
The auxiliary heating switches off when the
engine is switched off. The auxiliary ventilation
switches off when you turn the key to key posi-
tion 2(Y page 133).
The auxiliary heating switches off automatically
after 50 minutes.
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
(Y page 133).
X Set the desired temperature.
Auxiliary heating or ventilation can also be
switched on if the manually set climate control is
activated. Optimum comfort is attained by set-
ting the system to automatic mode. Set the tem-
perature to 22 †.
The auxiliary heating or auxiliary ventilation can be switched on/off using the button on the
centre console or the remote control.
The on-board computer can be used to specify
up to three departure times, one of which may
be preselected (Y page 211). Switching the auxiliary heating/venti-
lation on or off using the button on the
