Maintenance - Vauxhall VECTRA Owner's Manual

When cooling 3 (air c onditioning
compressor) is switched on, condensation
forms, which is ex pelled from the underside
of the v ehicle.
At lea st one air vent must b e open while
cooling 3 (air conditioning compressor) is
on in order to prevent the evaporator from
icing up due to lack of air movement.
Cooling switches off autom atically at low
outside tem peratures.
When the aux iliary hea ting/auxiliary
ventilation 3 is switched on, the Vauxhall
alarm system monitoring of the vehicle
interior 3 is deactivated.
Auxiliary heating 3 consumes fuel (a pprox.
0.3 litres per heating process on average).
When the aux iliary hea ting 3 is sw itched
on, there may briefly be some smoke and
noise.
The auxiliary heating 3 only switches itself
on at outside temperatures of less than
approx. 20 °C and a t coolant temperatures
of less than approx. 80 °C .
In order to im prov e heating power and
ensure that the engine operating
temperature is rea ched quickly , auxiliary
heating 3 also switches on automatically
when driving if the outside temp erature is
less than ap prox . 8 °C . This occurs
irresp ective of stored auxiliary heating
switch-on tim es. Aux iliary heating switches
itself off automatically when the engine is
switched off, while the combustion air fa n
continues running for ap prox . 2 minutes
(humming noise).
Climate control

Maintenance

In order to ensure consistently good
operation, the air conditioning
compressor 3 m ust be switched on for
sev eral minutes once per m onth
irrespective of the w eather or time of yea r.
If the vehicle has an Electronic Climate
C ontrol system, this is done automa tic ally
during travel. O peration with cooling (air
conditioning compressor) is not possible
when outside temperatures are low . Ev ery
6 m onths, the auxiliary heating 3 should be
operated for a few m inutes a t a preset
temperature above 22 ° C.
