AIR RECIRCULATION
Move slider D to position v to switch
internal air recirculation on.
It is advisable to switch internal air recir-
culation on while standing in queues or in
tunnels to prevent the introduction of pol-
luted air. Do not use the function for a
long time, particularly if there are many
occupants on board, to prevent the win-
dows from misting up.

IMPORTANT The inside air recirculation
system makes it possible to reach the re-
quired "heating" or "cooling" conditions
faster.
Do not use the air recirculation function
on rainy/cold days as it would consider-
ably increase the possibility of the win-
dows misting inside.
LOOKING AFTER THE SYSTEM
Run the climate control system for at least
10 minutes every month during the win-
ter. Have the system inspected at a Fiat
Dealership before the summer.
The system uses R134a re-
frigerant fluid which does not
harm the environment in the
event of accidental leakage.
Never use R12 fluid which is not com-
patible with the system components.
