Alfa Romeo 166 2006 Owner handbook (in English)

The dust/pollen filter should be checked
over at least once a year by Alfa Romeo
Authorized Services, preferably at the be-
ginning of summer.
If the vehicle is habitually driven in pol-
luted areas or on dusty roads the system
should be checked and if necessary
changed more often.If the filter is not re-
placed the efficiency of
the climate control sys-
tem may be seriously compro-
mised.ACTIVATED CARBON
DUST/POLLEN AIR FILTER
The filter has the specific capability to
combine the mechanical air filtering func-
tion with an electrostatic effect so that
the outside air admitted to the passenger
compartment is purified and free of parti-
cles such as dust, pollen etc.
In addition to the above-mentioned
function there is also an effective reduc-
tion of the concentration of pollutants
owing to a layer of activated carbons on
the lower surface of the filter.
The filtering action takes place when air
is admitted from outside (recirculation
off) and when the air is recirculated (re-
circulation on).

91
ADDITIONAL HEATER
(Optional, for diesel versions, where
applicable)
The additional heater makes it possible
to integrate heating of the engine coolant
fluid, immediately after starting the en-
gine and when travelling, to more quickly
reach and maintain the optimum operat-
ing temperature of the engine and pas-
senger compartment heater.
The device works completely automati-
cally and it is activated only when the en-
gine is running with an outside tempera-
ture of +5°C or less and a coolant fluid
temperature below 60°C.
When the coolant fluid reaches 61°C,
the electronic control unit reduces the
power of the burner and stops the heater
when a temperature of 72°C is reached,
reactivating it automatically when the flu-
id temperature falls below 60°C. Con-
versely, if after reducing the power of the
burner, the fluid temperature begins to
fall, the control unit cuts in to restore full
power.The system comprises:
– a fuel oil burner for heating the water
and a combustion gas exhaust silencer.
– A batching pump connected to the car
reservoir pipes to supply the burner.
– An electronic control unit for control-
ling burner adjustment.
– An outside temperature sensor.IMPORTANT The heater is fitted with
a thermal limiting device which cuts off
combustion in the event of overheating
due to lack/leaks of coolant fluid.
The heater is also protected by the auto-
matic fuel cut-off switch, which shuts off
the fuel in the event of a crash of a cer-
tain size: to see how this works see the
“automatic fuel cut-off switch” para-
graph.

92
The temperature near
the heater should never
exceed 120°C (e.g. dur-
ing body painting operations in
the workshop oven). Higher tem-
perature could damage the elec-
tronic control unit components.
For maintenance and repairs con-
tact only Authorized Alfa Romeo
Services and only use original
spare parts.
The burner exhaust gas
is released in the centre
floor area: therefore never park
the car with the engine running
over inflammable surfaces, fire
hazard!
WARNING
IMPORTANT When the heater is
working with the vehicle stationery and
the engine running, standing outside the
car near the rear wheel arch a low noise
caused by normal operation of the heater
can be heard.MAINTENANCE
Have the additional heater checked at
regular intervals by Authorized Alfa
Romeo Services. This will ensure safe,
cost-effective working of the heater and
also long life.
