WARNING ‑ Danger of bu rns or frostbite
due tobeing too close tothe air vents
Ve ry hot or very cold air can flow from the air
ve nts.
This could result in burns or frostbite in the
immediate vicinity of the air vents. #
Makesure that all vehicle occupants
alw ays maintain a suf ficient dis tance to
th e air vents. #
If necessa ry, direct the air flow to
ano ther area of theve hicle interior. Depending on
theve hicle equipment, there will
be an air duct or a heater with additional air vents
in there ar compartment foot we ll on the left-hand
side 1. No objects may be placed there. Occu‐

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. #
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
When thest ationary heater is swit ched on,
parts of theve hicle can become very hot, e.g.
