Eco-driving
Eco-driving is a range of everyday practices
that allow the motorist to optimise their fuel
consumption and CO
2 emissions.
Optimise the use of your gearbox
With a manual gearbox, move off gently
and change up without waiting. During
acceleration, change up early.
With an automatic gearbox, give preference
to automatic mode and avoid pressing the
accelerator pedal heavily or suddenly.
The gear efficiency indicator invites you to
engage the most suitable gear: as soon as the
indication is displayed in the instrument panel,
follow it straight away.
For vehicles fitted with an automatic gearbox,
this indicator appears only in manual mode.
Drive smoothly
Maintain a safe distance between vehicles,
use engine braking rather than the
brake pedal, and press the accelerator
progressively. These practices contribute
towards a reduction in fuel consumption and
CO
2 emissions and also help reduce the
background traffic noise.
If your vehicle has cruise control, make use of
the system at speeds above 25 mph (40 km/h)
when the traffic is flowing 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 around 30 mph (50 km/h), close the
windows and leave the air vents open.
Consider using equipment that can help
keep the temperature in the passenger
compartment down (sunroof blind and window
blinds...).
Unless it has automatic regulation, switch off
the air conditioning as soon as the desired
temperature has been reached. Switch off the headlamps and front foglamps
when the ambient light level does not require
their use.
Avoid running the engine before moving off,
particularly in winter; your vehicle will warm up
much faster while driving. Switch off the demisting and defrosting
controls, if these are not automatically
managed.
Switch off the heated seat as soon as possible.
As a passenger, if you avoid connecting your
multimedia devices (film, music, video game
etc.), you will contribute towards limiting the
consumption of electrical energy, and so of
fuel.
Disconnect your portable devices before
leaving the vehicle.

Lighting controls
System for selection and control of the various
front and rear lamps providing the vehicle's
lighting.
Main lighting
The various front and rear lamps of the vehicle
are designed to adapt the driver's visibility
progressively according to weather conditions:
-
s
idelamps, to be seen,
-

d
ipped beam headlamps to see without
dazzling other drivers,
-

m
ain beam headlamps to see clearly when
the road is clear.
In some weather conditions (e.g. low
temperature or humidity), the presence
of misting on the internal sur face of the
glass of the headlamps and rear lamps is
normal; it disappears after the lamps have
been on for a few minutes.
Additional lighting
Other lamps are provided to meet the
requirements of particular driving conditions:
-

situations, the power of their beams may
dazzle other drivers. They should only be
used in fog or falling snow.
In these weather conditions, it is your
responsibility to switch on the foglamps
and dipped headlamps manually as the
sunshine sensor may detect sufficient
light.
Switch off the front and rear foglamps
when they are no longer necessary. Switching off of the lighting when the
ignition is switched off
On switching off the ignition, all of the
lamps turn off immediately, except for
dipped beam if automatic guide-me-home
lighting is activated.

or solvent product,
F

u
se a sponge and soapy water or a pH
neutral product,
F

w
hen using a high pressure washer
on persistent marks, do not keep the
lance directed towards the lamps or
their edges for too long, so as not to
damage their protective coating and
seals.
Changing a bulb must only be done with
the ignition off and after the headlamp has
been switched off for several minutes –
Risk of serious burns!
F

D
o not touch the bulb directly with your
fingers, use a lint-free cloth.
It is essential only to use anti-ultraviolet
(UV) type bulbs, so as not to damage the
headlamp.
Always replace a failed bulb with a new
bulb with the same type and specification. In some weather conditions (e.g. low
temperature or humidity), the presence
of misting on the internal sur face of the
glass of the headlamps and rear lamps is
normal; it disappears after the lamps have
been on for a few minutes.
Light-emitting diodes (LED)
For the replacement of this type of lamp,
contact the dealer network or a qualified
workshop.
A LED (light-emitting diode) replacement
kit is available from the dealer network.
