167 Climate control
When cooling 3 (air conditioning
compressor) is switched on condensation
forms, which is expelled from the underside
of the vehicle.
At least one air vent must be 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 automatically at low
outside temperatures.
When the auxiliary heating/auxiliary
ventilation 3 is switched on the Vauxhall
alarm system monitoring of the vehicle
interior 3 is deactivated.
Auxiliary heating
3
consumes fuel (approx.
0.3 litres per heating process on average).
When the auxiliary heating
3 is switched
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 at coolant temperatures
of less than approx. 80 °C.
In order to improve heating power and
ensure that the engine operating
temperature is reached quickly, auxiliary
heating 3 also switches on automatically
when driving if the outside temperature is
less than approx. 8 °C. This occurs
irrespective of stored auxiliary heating
switch-on times. Auxiliary heating switches
itself off automatically when the engine is
switched off, while the combustion air fan
continues running for approx. 2 minutes
(humming noise).
Maintenance
In order to ensure consistently good
operation, the air conditioning
compressor 3 must be switched on for
several minutes once per month
irrespective of the weather or time of year.
If the vehicle has an electronic climate
control system, this is done automatically
during travel. Operation with cooling (air
conditioning compressor) is not possible
when outside temperatures are low. Every
6 months, the auxiliary heating 3 should be
operated for a few minutes at a preset
temperature above 22 °C.
On faults, contact a workshop.
