Auxiliary heating (auxiliary warm-air heater)
48
The air-intake opening in the auxiliary heating is
underneath the driver's seat. The vent is on the
rear side of the driver's seat base. Always make
sure that both openings are free from obstruc-
tion.
! If you are planning an extended stay at an
elevation over 1500 m with the vehicle, the
fuel supply to the auxiliary heating must be
adjusted.
Have this work carried out at a qualified spe-
cialist workshop. Operation of the auxiliary
heating cannot otherwise be guaranteed.
Parts of the auxiliary heating can be damaged.
There are no restrictions to the heating mode up
to an altitude of 1,500 m and for short stays over
1,500 m. Short stays are rest breaks or driving
through mountain passes, for example.
