AIR CONDITIONING: information and advice on use
Fuel consumption
You will normally notice an increase
in fuel consumption (especially
when driving in town) when the air
conditioning is operating.
For vehicles fitted with manual air
conditioning, switch off the system
when it is not required.
Advice for reducing consumption
and therefore helping to preserve
the environment:
Drive with the air vents open and
the windows closed.
If the vehicle has been parked in
the sun, open the doors for a few
moments to let the hot air escape
before starting the engine.
Maintenance
Refer to the Maintenance Service
Booklet for your vehicle for the in-
spection frequency.
Vehicles fitted with an auxiliary
heater
Some vehicles are fitted with an
auxiliary heater which heats the pas-
senger compartment more quickly.
This device operates only when
the engine is running and in cold
weather.
When the device is functioning you
can normally see a small amount of
smoke on the right-hand side of the
vehicle coming from the heater’s ex-
haust system.
Operating faults
As a general rule, contact your ap-
proved dealer in the event of an op-
erating fault.
– Reduction in de-icing, demist-
ing or air conditioning per-
formance. This may be caused
by the passenger compartment
filter cartridge becoming clogged.
– No cold air is being produced.
Check that the controls are set
correctly and that the fuses are
sound. Otherwise, switch off the
system.
Do not open the refriger-
ant fluid circuit. The fluid
may damage eyes or skin.
Notes
Presence of water under the ve-
hicle. After prolonged use of the air
conditioning system, it is normal for
water to be present under the vehi-
cle. This is caused by condensation.
Do not add anything to the
vehicle’s ventilation circuit
(for example, to remove
bad odours).
There is a risk of damage or of
fire.
