Heating and cooling
Note
WARNING
– For optimum air quality inside the vehicle,
close all windows and doors and activate
the A/C cooling mode, the AUTO function
and the automatic recirculation.
– The auxiliary heating must not be allowed to
run when the vehicle is in a confined space –
risk of poisoning!
– Never have the auxiliary heating switched on
when refuelling the vehicle – risk of fire!
– Because of the high temperatures which oc-
cur when the auxiliary heating is running,
make sure when parking the car that the ex-
haust outlet under the car is not obstructed
in any way and that the exhaust gases do
not come into contact with flammable ma-
terials (fire risk).
– Applies to vehicles with particulate sensor:
The air quality index only represents the
particulate level (PM2.5). For technical rea-
sons, there may be variations between the
values measured in the vehicle and the val-
ues measured by other instrumentation sys-
tems.
Steering wheel heating
Note
Switching on/off
– The auxiliary heating/ventilation will not
switch on or will switch itself off earlier
than intended if the battery charge or fuel
level is low.
Applies to: vehicles with steering wheel heating
►
Press the button to switch the steering
wheel heating on/off.
– The auxiliary heating/ventilation system
heats/cools the interior to the temperature
last selected on the air conditioner control
console.
You can also operate the steering wheel heating
using the controls on the multi-function steering
wheel ðpage 36.
– If the auxiliary heating/ventilation is on, it is
not switched off automatically when the en-
gine is started or stopped.
Auxiliary heating/
ventilation
– At low outside temperatures, some visible
water vapour may form in the engine com-
partment. This is a normal phenomenon,
and no reason for concern.
Description
Applies to: vehicles with auxiliary heating/ventilation
The auxiliary heating warms up the inside of the
vehicle, while the auxiliary ventilation draws in
fresh air and can lower the temperature inside
the vehicle, depending on the ambient tempera-
ture. The function can be used either when the
engine is off or when driving (for instance while
the engine is warming up).
