DANG ER Risk of fata l injury due topoi‐
sonous exhaust gases
If th eta ilpipe is bloc ked or suf ficient ventila‐
tion is not possible, poisonous exhaust gases
such as carbon monoxide may enter theve hi‐
cle. This is the case in enclosed spaces or if
th eve hicle getsst uck in sn ow,fo rex ample. 12 6

#
Always switch thest ationary heater off
in enclosed spaces without an air
ex traction sy stems, e.g. in garage s. #
Keep theta ilpipe and the area around
th eve hicle free from snow when the
engine or thest ationary heater are run‐
ning. #
Open a window on the windward side of
th eve hicle toensure an adequate sup‐
ply of fresh air. &
WARNING Risk offire due tohot station‐
ary heater components and exhaust
ga ses
Flammable materials such as lea ves, grass or
twigs may ignite. #
When thest ationary heater is swit ched
on, make sure that:
R hot vehicle parts do not come into
contact with flammable materials.
R theex haust gas can flow out of the
st ationary heater exhaust pipe
unhindered.
R theex haust gas does not come into
contact with flammable materials. The heater
forth e auxiliary heating is fitted at the
front of theve hicle underbody. The emissions
outlet is on the left side of theve hicle below the
front door. &
WARNING Risk of poisoning duri ngwork
on the auxiliary warm-air hea ter
If wo rkon the heat exchanger of the auxiliary
wa rm-air hea ter is not per form ed cor rectl y,
ex haust fumes could leak into the passenger
compartment. #
Have all workon the auxiliary warm-air

ur vehicle may be equipped with either a hot-

The hot-water auxiliary heater is adjusted and
operated using the003B rock er switch on the cli‐
mate cont rol sy stem cont rol panel and via the
multimedia sy stem or byremo tecontrol.
The auxiliary warm-air heater is adjusted and

Obser vethe no tes on auxiliary heating
(/ page 126).
The hot-water auxiliary hea ter has a heater boos‐
te r,stationary heater and stationary ventilation
function. In addition, the auxiliary heating sy stem
heats the engine coolant toprotect the engine.
The stationary heater automatically adapts its
operating mode tochanges in outside temp era‐
ture and weather conditions. It is therefore possi‐
ble that thest ationary heater may swit chfrom
ve ntilation toheating mode or from heating to
ve ntilation mode.
The stationary heater will automatically swit ch
itself off af ter a maximum of 50 minutes. The
heater boos ter function helps toheat up theve hi‐
cle while the engine is running and at low outside
te mp eratures.
Yo u can set up tothre e departure times for pre-
entry clima tecontrol byremo tecontrol or via the
multimedia sy stem. The switch-on time is then
calculated based on the outside temp erature and
th e activated departure time. This means that
yo ur vehicle is preheated or precooled bythe set
departure time.
If th e departure time is reached and the engine is
not star ted, the auxiliary heating will continue to Climate cont
