Air conditioning

The auxiliary heating/ventilation is auto-
matically deactivated after about 30
minutes, or when:
R the ignition is switched on
R the battery voltage drops Auxiliary heating/ventilation*
G
Risk of poisoning
Exhaust fumes are produced when the aux-
iliary 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 system, 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 stations
or when your vehicle is being refuelled. You
must therefore switch off the auxiliary heat-
ing at filling stations.
The auxiliary heating heats the air in the vehi-
cle interior to a temperature between 20 °C and 24 °C without using the heat of the run-
ning engine. The auxiliary heating is operated
using fuel directly from the vehicle's fuel tank.
For this reason, the tank content 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 automatically switch over
from ventilation mode to heating mode or
from heating mode to ventilation mode.
You cannot use the auxiliary ventilation to
cool the vehicle interior to a temperature
lower than the outside temperature.
Before activating
X
Set the temperature to a value between
20 † and 24 †.
The auxiliary heating/ventilation can be acti-
vated even when the air conditioning is being
controlled manually. Optimum comfort can
be attained when the system is set to auto-
matic mode. Set the desired temperature
within this range. If a higher temperature is
set, the vehicle is heated to 24 †. If a lower
temperature is set, the vehicle is heated to
20 †. Activating or deactivating the auxiliary
heating/ventilation The auxiliary heating/ventilation can be acti-
vated or deactivated via 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 128).
Button on the centre console 1
Button for auxiliary heating/ventilation
The indicator lamps in the button may light up
in blue, red or yellow.

Problem Possible cause/consequence Suggested solutions
The engine will not start. HOLD is activated. X
Deactivating HOLD (Y page 145).
X Start the engine again. The engine will not start. You can
hear
the starter motor operating. R
There may be a malfunction in
the engine electronics.
R There may be a malfunction in
the fuel supply. X
Turn the key back to position 0 in the ignition lock before the next
starting attempt.
X Try to start the engine again (Y
page 101). When doing so, remem-
ber that excessively long and frequent attempts to start the engine
will drain the battery.
If the engine does not start after several attempts:
X Consult a qualified specialist workshop. Vehicles with a diesel engine:
The

engine will not start. You can
hear the starter motor operating.
The reserve fuel warning lamp is
on and the fuel gauge shows 0. The fuel tank has been run dry. X
Refuel the vehicle.
X Bleed the fuel system (Y page 254). The engine will not start. You can-
not hear the starter motor oper-
ating. The on-board voltage is too low
because

the starter battery is too
weak or discharged. X
Jump-start the vehicle (Y page 291).
If the engine does not start despite attempting to jump-start it:
X Consult a qualified specialist workshop. Practical advice
