ECO-DRIVING

Optimise the use of your
gearbox

With a manual gearbox, move off
gently, change up without waiting
and drive by changing up quite soon.
If your vehicle has the system, the
gear effi ciency indicator invites you to
change up; it is displayed in the instru-
ment panel, follow its instructions.

With an automatic or electronic gear-
box, stay in Drive "D"
or Auto "A"
, ac-
cording to the type of gearbox, without
pressing the accelerator pedal heavily
or suddenly.



Drive smoothly


Maintain a safe distance between ve-
hicles, use engine braking rather than
the brake pedal, and press the accel-
erator progressively. These practices
contribute towards a reduction in fuel
consumption and CO
2 emissions and
also helps reduce the background
traffi c noise.

If your vehicle has cruise control, make
use of the system at speeds above
25 mph (40 km/h) when the traffi c is
fl owing well.



Control the use of your
electrical equipment

Before moving off, if the passenger
compartment is too warm, ventilate it
by opening the windows and air vents
before using the air conditioning.
Above 30 mph (50 km/h), close the win-
dows and leave the air vents open.
Remember to make use of equipment
that can help keep the temperature
in the passenger compartment down
(sunroof and window blinds...).
Switch off the air conditioning, unless
it has automatic digital regulation, as
soon as the desired temperature is at-
tained.
Switch off the demisting and defrosting
controls, if not automatic.
Switch off the heated seat as soon as
possible.

Switch off the headlamps and front fo-
glamps when the level of light does not
require their use.
Avoid running the engine before mov-
ing off, particularly in winter; your ve-
hicle will warm up much faster while
driving.

As a passenger, if you avoid connect-
ing your multimedia devices (fi lm, mu-
sic, video game...), you will contribute
towards limiting the consumption of
electrical energy, and so of fuel.
Disconnect your portable devices be-
fore leaving the vehicle.
Eco-driving is a range of everyday practices that allow the motorist to optimise their fuel consumption and CO
2 emissions.
