Engine Adjustments - Renault Scenic Driver's Handbook Manual

ADVICE: emission control, fuel economy, driving
RENAULT is actively striving to reduce
pollutant exhaust gas emissions and
to save energy. By virtue of its design,
moderate fuel consumption and ini-
tial settings, your RENAULT conforms
to current antipollution regulations.
Technical design, however, cannot
achieve all. The fuel consumption of
your vehicle and the level of pollutant
exhaust gas emissions are also your
responsibility. Make sure that your ve-
hicle is maintained and used correctly.
2.16
Maintenance
It should be noted that failure to respect
antipollution regulations may lead to
legal action being taken against the
vehicle owner. In addition, replacing
engine, fuel supply system and exhaust
components with parts other than those
originally recommended by the manu-
facturer may alter your vehicle so that
it no longer complies with antipollution
regulations.
Have your vehicle checked and ad-
justed by your RENAULT Dealer in ac-
cordance with the instructions in the ve-
hicle's Maintenance Service Booklet.
Your RENAULT Dealer has all the
equipment necessary for ensuring that
your vehicle is maintained to its original
standard.

your RENAULT Dealer for this infor-
mation.

justment.
