Advice: antipollution and fuel economy
aDVICe: antipollution, fuel economy and driving (1/3)
Your vehicle complies with criteria for
recycling and recovering vehicles at the
end of their service life which will come
into force in 2015.
Some parts of your vehicle have there-
fore been designed to facilitate future
recycling.
These parts are easy to remove so
that they can be recovered and reproc-
essed by recycling companies.
By virtue of its design, moderate fuel
consumption and initial settings, your
vehicle also conforms to current anti-
pollution regulations. The manufac -
turer is actively striving to reduce pol -
lutant exhaust gas emissions and to
save energy. But the fuel consumption
of your vehicle and the level of pollutant
exhaust gas emissions are also your
responsibility. Ensure that it is main -
tained and used correctly.aiding fuel economy
Depending on the vehicle, in order to
optimise consumption, an indicator light
on the instrument panel will inform you
of the best moment to upshift or down -
shift gears:
\ shift up a gear;
[ shift down a gear.
Maintenance
It is important to remember that failure to
respect antipollution regulations could
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 adjusted and
checked by an approved Dealer, in ac-
cordance with the instructions given in
your maintenance schedule: they will
have all the equipment necessary for
ensuring that your vehicle is maintained
to its original standard.

engine. Contact an approved dealer
for this.
