FILTER-DRIER -- Figure 95
A sight glass and a ring-shaped moisture indicator F
on the right-hand side of the engine cover serve for
determining the condition of the R134a gas.
S If the refrigerant is without air bubbles, then the re-
frigerant condition is good.
S If the glass shows a milky refrigerant: satisfactory
performance is ensured.
S If air bubbles are visible: lack of refrigerant.
S If the moisture indicator is blue: filter and refriger-
ant are in good condition.
S If the moisture indicator is red: this is an indication
of too much moisture, the filter-drier has to be re-
placed.
If the filter-drier needs to be replaced or if the air con-
ditioning system needs repair , contact your local
dealer.
