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 adjustments–
ignition: this does not require ad -
justment.
– spark plugs: for optimum fuel econ-
omy, efficiency and performance
the specifications laid down by our
Design Department must be strictly
applied.
If the spark plugs have to be
changed, use the make, type and
gap specified for your vehicle’s
engine. Contact an approved dealer
for this.
– idle: this does not require adjust -
ment.
– air filter, diesel filter: a clogged ele-
ment reduces performance. It must
be replaced.

emissions
Your vehicle has been designed to
emit fewer greenhouse gases (CO2)
while in use, and therefore to consume
less fuel (eg. 140 g/km, equivalent to
5.3 l/100 km for a diesel vehicle).
Our vehicles are also equipped with a
particle filter system including a cata -
lytic converter, an oxygen sensor and
an active carbon filter (the latter pre -
vents vapour from the fuel tank being
released into the open air).
For certain diesel vehicles, this system
also has a particle filter to reduce the
volume of soot particles emitted.
Please make your own
contribution towards
protecting the environment
too
– Worn parts replaced in the course of
routine vehicle maintenance (vehi -
cle battery, oil filter, air filter, batter -
ies, etc.) and oil containers (empty or
filled with used oil) must be disposed
of through specialist organisations. –
At the end of the vehicle’s service
life, it should be sent to approved
centres to ensure that it is recycled.
– In all cases, comply with local legis -
lation.
Recycling
Your vehicle is 85% recyclable and
95% recoverable.
To achieve these objectives, many of
the vehicle components have been de-
signed to enable them to be recycled.
The materials and structures have
been carefully designed to allow these
components to be easily removed and
reprocessed by specialist companies.
In order to preserve raw material re -
sources, this vehicle incorporates nu -
merous parts made from recycled plas-
tics or renewable materials (vegetable
or animal-derived materials such as
cotton or wool).
Your vehicle has been designed with
respect for the
environment in mind for
its entire service life: during production,
use and at the end of its life.
This commitment is illustrated by the of
the manufacturer eco² signature.Manufacture
Your vehicle has been manufactured at
a factory which complies with a policy
to reduce the environmental impact
on the surrounding areas (reduction of
water and energy consumption, visual
and noise pollution, atmospheric emis-
sions and waste water; sorting and re-
using waste).

Air conditioning: information and advice on use
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 Document
for your vehicle for the inspection
frequency.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.
Advice on use
In some situations, (air conditioning
off, air recirculation activated, venti-
lation speed at zero or low, etc.) you
may notice that condensation starts
to form on the windows and wind -
screen.
If there is condensation, use the
“clear View” function to remove it,
then use the air conditioning in auto-
matic mode to stop it forming again.
If the condensation does not clear,
use the FAST programme.
Do not open the refriger -
ant fluid circuit. The fluid
may damage eyes or skin.
Note
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.
