Operation of automatic front-passenger
front airba gdeactivation :
PASSENGER AIR BAG ON indicator lamp
; PASSENGER AIR BAG OFF indicator lamp
The indicator lamps show you whether the co-
driver's fron tairbag is disabled or enabled.
X Press the Start/Stop button onceort wice or
turn the key to position 1or 2in the ignition
lock.
The system carries out aself-diagnosis.
The PASSENGER AIR BAG OFF and PASSENGER
AIR BAG ON indicator lamps must light up simul- taneously for approximately six seconds.
The indicator lamps then show the status of the
co-driver's fron tairbag.
R PASSENGER AIR BAG ON is lit: the co-driver's
fron tairbag is enabled. If, in the case of an
accident, all deployment criteria are met, the
co-driver's fron tairbag is deployed.
R PASSENGER AIR BAG OFF is lit: the co-driv-
er's fron tairbag is disabled. It will then not be
deployed in the event of an accident.
If the status of the co-driver's fron tairbag
changes while the vehicle is in motion ,anairbag
display message appears in the instrument clus-
ter (Y page 263). When the co-driver's seat is
occupied, alway spay attention to the
PASSENGER AIR BAG ON and PASSENGER AIR
BAG OFF indicator lamps. Be aware of the status of the co-driver's fron tairbag both before and
during the journey.
If ap erson is occupying the co-driver's seat,
they must sit:
R with the seat belt fastened correctly
R in an almost upright position with their back
against the seat backrest
R with their feet restin gonthe floor, if possible If the co-driver does not observe this, the auto-
matic co-driver's fron tairbag deactivation sys-
tem may be influenced, for example if the co-
driver:
R transfers their weight by supportin gthem-
selves on avehicle armrest
R sits in such away that their weight is raised
from the seat cushion
This or similar behaviour can cause the co-driv-
er's fron tairbag to be deactivated when it
should not be. In this case, PASSENGER AIR BAG OFF indicator lamp lights up continuously. The
co-driver's fron tairbag is then not deployed in
an accident. G
WARNING
If the PASSENGER AIRBA GOFF indicator lamp
is lit, the front-passenger fron tairbag is disa-
bled. It will not be deployed in the event of an
acciden tand cannot perform its intended pro-
tective function .Aperson in the front-
passenger seat could then ,for example, come
into contact with the vehicle's interior, espe-
cially if the person is sitting too close to the
dashboard. This poses an increased risk of
injur yore ven fatal injury.
When the front-passenger seat is occupied,
alway smake sure that:
R the classification of the person in the front-
passenger seat is correct and that the front-
passenger fron tairbag is enabled or disa-
bled in accordance with the person in the
front-passenger seat.
R the front-passenger seat has been moved
back as far back as possible.
R the person is seated correctly.
Make sure, both before and during the jour-
ney, that the status of the front-passenger
fron tairbag is correct. G
WARNING
If you secure achild on the co-driver's seat in
ar earward-facing child restraint system and
the PASSENGER AIR BAG ON indicator lamp
lights up, the co-driver's airbag could be
deployed in the event of an accident. The child could be struc kbythe airbag. There is an
increased risk of injury, possibly even fatal. 48

Operating the auxiliary heating/ventilation
draws on the vehicle battery. After you have
heated or ventilated the vehicle amaximum of
two times, drive for alonger distance.
Switch the auxiliary heating on regularly once a
month for aboutt en minutes.
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 tank content
must be at least at reserve fuel level to ensure
that the auxiliary heating functions.
The auxiliary heating or auxiliary ventilation
automaticallya djusts to changes in tempera-
ture and weather conditions. For this reason,
the auxiliary heating could switch from ventila-
tion 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
is not active if the engine is running.
The auxiliary heating or auxiliary ventilation
switches off automaticallya fter 50 minutes.
This time limit can be altered. To do this, visit a
qualified specialist workshop.
You cannot use the auxiliary ventilation to cool
the vehicle interior to atemperature lower than
the outside temperature.

(Y page 145).
X Set the desired temperature using the w
rocker switch on the front control unit.
If you do not alter the temperature before
switching on the auxiliary heating or auxiliary
ventilation, the last temperature setting will be
adopted.
Auxiliary heating or auxiliary ventilation can also
be switched on if the manuallys et climate con-
trol is activated. Optimum comfort is attained
when the system is set to automatic mode. Set the temperature to 22 †.
You can switch the auxiliary heating or auxiliary
ventilation on or off:
