AIR CONDITIONING: information and operating advice
Fuel consumption
You will normally notice an
increase in fuel consumption
(especially in town) when the air
conditioning is operating.
Switch off the air conditioning
when it is not required on vehicles
fitted with manual air
conditioning.
Some advice for reducing
consumption and therefore
helping to preserve the
environment:
It is advisable to drive with the
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
replacement frequency.
Operating faults
Generally, in the event of an
operation fault, consult your
RENAULT Dealer.
- Reduction in de-icing, demisting
or air conditioning performance.
This may be caused by the
passenger compartment filter
cartridge becoming clogged.
- Nocoldairisbeingproduced.
Check that the controls are set
correctly and that the fuses are
sound. Otherwise, switch off the
system.
- Presence of water under the
vehicle. After prolonged use of
the air conditioning system, it is
normal for water to be present
under the vehicle. This is caused
by condensation.
Vehicles fitted with an auxiliary
heater
Some vehicles are fitted with an
additional heater located in the
engine compartment which
enables the passenger
compartment to be heated more
quickly.
This device only operates when the
engine is running and in cold
weather; it is controlled by the
exterior temperature and the
coolant temperature. The gases
produced when it operates escape
via a tube coming from the front
right-hand side of the vehicle.
When you stop the engine, the
heater ventilation fan continues to
operate for a few seconds. It is not
necessary to wait for it to stop
before filling the tank.
