ADVICE ON ANTIPOLLUTION AND HOW TO ECONOMISE ON FUEL WHEN DRIVING
RENAULT actively participates in
the reduction of pollutant exhaust
gas emissions and in saving energy.
By virtue of its design, its original
settings and moderate fuel
consumption, your RENAULT
conforms to the current antipollution
standards. Technical design cannot
achieve everything, however. The
level of exhaust gas pollutant
emissions and the fuel
consumption of your vehicle is
within your control. Ensure that
your vehicle is maintained
correctly, and that you drive and use
it carefully.Maintenance
Not observing the antipollution
legislation may lead to the owner of
the vehicle being prosecuted.
Replacing parts of the engine, the
fuel supply system and the exhaust
with parts which are not original
parts recommended by the
manufacturer may mean that your
vehicle no longer conforms to the
antipollution regulations.
Have your vehicle checked and
adjusted by your Renault Dealer in
accordance with the instructions in
your Warranty and Servicing booklet.
Your Renault Dealer has all the
equipment necessary to ensure that
your vehicle is maintained to its
original standard.
Always remember that the emission
of pollutant fumes is directly linked
to fuel consumption.
Engine adjustments
• ignition:this requires no adjustment
• spark plugs:optimum conditions
of use, performance and output
require that the specifications
laid down by our Design
Department be rigorously
adhered to.
If the spark plugs have to be
replaced, use the make, type and
gap specified for your engine.
Consult your Renault Dealer for
this information.
• idle speed:this requires no
adjustment.
• air filter, diesel fuel filter:a
blocked cartridge reduces output
and must be replaced.
• injection pump setting:this must
be set to the recommended values.
