Heating menu Auxiliary heating departuret
ime
This function is only availabl eonvehicles with
auxiliary heating (Y page 137).
In the Heating submenu, you can select a
stored departure time or change adeparture
time. The auxiliary heating timer function calcu-
lates the switch-on time accordin
gtothe out-
side temperature so that the vehicle is pre-
heated by the departure time. When the
departure time is reached, the auxiliary heat-
ing continues to heat for afurther five
minutes and then switches off. The auxiliary
heating adopts the THERMATIC or
THERMOTRONIC temperature setting.
You can switch off the auxiliary heating by
using the remot econtrol or the auxiliary heat-
ing button on the centre console. G
WARNING
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. agarage. G
WARNING
When operating the auxiliary heating parts of
the vehicle can get very hot. Make sure that
the exhaust system does not under any cir-
cumstances come into contact with easily
ignitable material such as dry grass or fuels.
The material could otherwise ignite and set
the vehicle alight. Choose your parking spot
accordingly.
Operating the auxiliary heating is thus pro-
hibited at filling station sorwhen your vehicle
is being refuelled. You must therefore switch
off the auxiliary heating at filling stations.
! 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.
