Setting the desired temperature
• Open all the ventilation nozzles
• Turn on the fan (3)
• Set desired air distribution (5)
• Set desired cooling or heating (2)
• If necessary, start the air conditioning (1)
When it is hot outside, it is normal that water drips
from in the truck. This is harmless condensation
coming from the air conditioning.
Remove mist and ice from windows
• Check that recirculation is turned off
• Set the fan to the highest possible speed
• Set the air distribution to defroster
• Set the temperature to maximum heat or the fan to
max
In AUT/defrost mode with cold temperatures, the
windscreen can become so warm that snow smoke
melts on it. This can cause the wiper blades to freeze
to the windscreen. Set the air distribution to the floor
only. The floor setting can also be used together with
the defroster to remove mist from the side windows.
Clean the inside of the windscreen with a normal
window cleaning fluid to reduce the risk of misting up.
Clean more frequently if someone smokes in the cab.
With cold outdoor temperatures, mist and ice can
occur on the side windows. To avoid this, close the
inner panel nozzles and aim the side nozzles at the side
windows.
Cab 325
Note!
Do not use recirculation with high
humidity or heavy rain. It is
necessary to draw in new air and
have the AC on to prevent the
windscreen from misting up.
