Useful information

These Operating Instructions describe all the
models and standard and optional equipment
of your vehicle that were available at the time
of going to print. Country-specific differences
are possible. Bear in mind that your vehicle
may not be equipped with all the functions
described. This also applies to safety-relevant
systems and functions.
Read the information on qualified specialist
workshops ( Y page 30).
General notes
The heating or the air-conditioning system
can only be operated with the engine running.
To ensure optimal function, close the win-
dows.
The air-conditioning system regulates the
temperature and humidity of the cab and
removes undesirable substances from the air.
In air-recirculation mode, the fitted filter
removes most dust particles and pollen from
outside air or recirculated air. A blocked filter
reduces the amount of air supplied to the cab.
The interval for replacing the filter depends on
environmental influences. It may be shorter
than that indicated in the Service Booklet.
Ventilate the vehicle for a brief period during
warm weather. In order to cool the vehicle
more rapidly, briefly switch climate control to
air-recirculation mode. This will speed up the
cooling process and the desired interior tem-
perature will be reached more quickly.
Condensation may appear on the underside
of the vehicle in cooling mode.
! Turn on the air-conditioning system at
least once a month for approximately ten
minutes. The refrigerant compressor may
otherwise be damaged.

Environmental note
Only switch on the air-conditioning system
when necessary. Fuel consumption increases
when the air-conditioning system is switched
on.
