ECO-DRIVING
Optimise the use of your gearbox
With a manual gearbox, move off gently and change up without
waiting. While accelerating changing up early. If your vehicle has
the system, the gear efficiency indicator invites you to engage the
most suitable gear; follow its instructions as soon as it is displayed
in the instrument panel.
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 helps 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 30 mph (50 km/h), close the windows and leave the air
vents open.
Remember to make use of equipment that can help keep the
temperature in the passenger compartment down (window
blinds...).
Switch off the air conditioning, unless it has automatic digital
regulation, as soon as the desired temperature is attained.
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 foglamps when the level of
light does not require their use.
Eco-driving is a range of everyday practices that allow the motorist to \
optimise their fuel consumption and CO
2 emissions.
Avoid running the engine before moving off, particularly in winter;
your vehicle will warm up much faster while driving.
As a passenger, if you avoid connecting your multimedia devices
(film, music, video game...), you will contribute towards limiting the\

consumption of electrical energy, and so of fuel.
Disconnect your portable devices before leaving the vehicle.

Driving safely
HORN
Press the centre of the steering wheel.
Anti-lock braking system and electronic brake force distribution
Linked systems which improve the stability
and manoeuvrability of your vehicle when
braking, in particular on poor or slippery
surfaces.
Operation
The anti-lock braking system comes into
operation automatically when there is a risk
of wheel lock.
Normal operation of the ABS may make
itself felt by slight vibration of the brake
pedal accompanied by some noise.
When braking in an emergency, press
very firmly without releasing the
pressure.
Switching off
These systems cannot be deactivated by
the driver.
BRAKING ASSISTANCE SYSTEMS
Group of supplementary systems which help
you to obtain optimum braking in complete
safety in emergency situations:
- anti-lock braking system (ABS),
- electronic brake force distribution (EBFD),
- emergency braking assistance (EBA).

CHECKS
Levels and checks
Manual gearbox
Have the level checked in accordance with
the manufacturer's servicing schedule.
Good practice
To check the main levels and certain
components, in accordance with the
manufacturer's servicing schedule, refer to
the pages of the maintenance and warranty
guide which correspond to your vehicle's
engine.
Only use products recommended by
CITROËN or products of equivalent quality
and specification.
In order to optimise the operation of units as
important as the braking system, CITROËN
selects and offers specific products.
Oil filter
Change the filter regularly, in accordance
with the manufacturer's servicing schedule.
Brake pads
Brake pad wear depends on the style of
driving, in particular for vehicles which are
used in town, over short distances. It may
be necessary to check the thickness of the
pads, even between services.
Brake disc/drum wear status
For any information relating to checking
the brake disc/drum wear status, contact a
CITROËN dealer or a qualified workshop.
Parking brake
Where the parking brake travel is too great
or there is a reduction in the performance
of the system, the parking brake should be
adjusted, even between services.
Have the system checked by a CITROËN
dealer or a qualified workshop.
If this warning lamp comes on,
have the brake pad wear checked
by a CITROËN dealer or a
qualified workshop. In order to avoid damaging the
electrical units, high pressure washing
to clean the engine compartment is strictly
prohibited.
After washing the vehicle dampness, or in
winter, ice may form on the brake discs and
pads: braking efficiency may be reduced.
Make some light brake applications to dry
and de-ice the brakes.
