Applies to vehicles: with deluxe automatic air conditioner plusAutomatic recirculation
If the outside air is polluted, an air purity sensor in the
vehicle will automatically switch on the air recirculation.To prevent fumes, etc. in the outside air from entering the interior,
we recommend that the automati c air recirculation should be
switched on at all times.
If the air purity sensor in the air conditioner system detects a certain
concentration of fumes in the outside air, the control unit will either
pass the incoming air through the pollution filter or automatically
switch on the air recirculation. If there is a high concentration of
pollution in the outside air, the air conditioner automatically
switches to air recirculation and cuts off the supply of air from the
outside. As soon as the level of pollution decreases, air is fed into
the vehicle from the outside again.
If the windows mist up when the automatic air recirculation is on,
press the
button immediately.
The automatic air recirculation can switch itself off in certain condi-
tions. If the outside temperature is less than about +10 °C, the auto-
matic air recirculation will only operate for 30 seconds. If the air
conditioner is switched to the ECON mode, or if the outside temper-
ature is less than about -1 °C, th e automatic air recirculation will
only operate for 15 seconds.
Applies to vehicles: with deluxe automatic air conditioner plusSynchronisation
The air conditioner settings can be synchronised for all
passengers.When the synchronisation function is switched on, all subsequent
air conditioner settings made on the driver's side (except for the
seat heating*) are also applied to the front passenger's side.

110The synchronisation is cancelled as soon as any adjustments are
made on the front passenger's side.Applies to vehicles: with diesel engineSupplementary heater– Set the Supplementary heater to auto or off .Models with a diesel engine are equipped with a supplementary
heater to help warm up the interior more quickly. At outside temper-
atures below about +5 °C the sup plementary heater is switched on
(and off) automatically when the engine is running, depending on
the coolant temperature, the temperature in the vehicle interior and
the temperature the heater is set to.Auxiliary heating and auxiliary
ventilationApplies to vehicles: with auxiliary heating - under development at the time of printingDescription
The auxiliary heating and ventilation systems heat and
cool the interior independently of the engine.The auxiliary heating
works in conjunction with the air condi-
tioner system, but does not rely on heat from the engine. Instead of
this, the system burns fuel. The system's main function is to warm
up the interior of the vehicle and to defrost the windows in cold
weather.
The auxiliary heating system can be used both when the vehicle is
stationary and when driving (to pr ovide extra heat while the engine
is warming up). The
auxiliary ventilation
also operates independently of the
engine. This feature can be used to cool the interior with the blower
when the vehicle is left parked in the sun.
The system will automatically activa te either the auxiliary heating or
the auxiliary ventilation mode, depending on the actual tempera-
ture measured inside the car and the temperature you have set with
the air conditioner controls. It is possible to alter the temperature
setting while the auxiliary he ating/ventilation is running.
Switching on and off
There are two different ways of switching on the auxiliary
heating/ventilation system.
•
Immediate start: You can switch the auxi liary heating/ventilation
on and off at any time vi a the sound system or MMI ⇒page 111 . You
can also switch the system on and off using the remote control
⇒ page 113 .
•
Switching on via timer: You can programme various start times
using the timers ⇒page 111 . However you must first activate the
timer before the auxiliary heating/ventilation system will switch on
automatically.
The auxiliary heating/ventilation will switch itself off at the end of
the programmed running time. The running time can be set to 15,
30, 45 or 60 minutes ⇒page 112 .
WARNING
•
The auxiliary heating must not be allowed to run when the
vehicle is in a confined space because it can give off toxic fumes.
•
To avoid any possible fire risk, never have the auxiliary heating
switched on when refuelling the vehicle.
•
Because of the high temperatur es which occur when the auxil-
iary heating is running, make su re when parking the car that the
exhaust outlet under the car is not obstructed in any way and that
the exhaust gases do not come into contact with flammable mate-
rials (fire risk).
