As a passenger, if you avoid connecting your
m ultimedia 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.
Eco- driving
Eco-driving is a range of everyday practices that allow the motorist to optimise their fuel consumption and CO2 emissions.
Optimise the use of your
gearbox
With a manual gearbox, move off gently
an d 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,
u se 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 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, etc.). 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. Unless it has automatic regulation, switch off
the air conditioning as soon as the desired
temperature has been reached.
Switch off the demisting and defrosting
controls, if these are not automatically
managed.
Switch off the heated seat as soon as
possible.

Indicators
Service information
For a few seconds after the ignition is
s witched on, the spanner symbolising ser vice
information comes on: the screen informs you
when the next ser vice is due, in accordance
with the ser vicing schedule indicated in the
manufacturer's service schedule.
Engine oil level
Depending on the engine, the engine oil level
then appears, graduated from 1 (Min.) to
5


( M a x .) .
If no graduation is displayed, the oil level is
too low; it is essential that you top up to avoid
damaging the engine.
For the oil level reading to be accurate, the
vehicle must be parked on level ground, with
the engine off for more than 30
minutes.
This information is determined in relation to the
distance travelled since the previous service. If in doubt, check the level with the
dipstick.
For more information on Checking levels
,
refer to the corresponding section.
Engine oil condition
This warning lamp flashes and,
if your vehicle has this function,
a message is displayed at every
engine start: the system has
detected deterioration of the engine
oil. Have the oil changed as soon as
possible.
This 2nd warning lamp, coupled with the
1st, comes on in the instrument panel
when the oil has not been changed and
the deterioration of the oil has gone
beyond a
new threshold. If this warning
comes on at regular inter vals, have the
oil changed as soon as possible.
For 3.0 litre HDi engines, the engine
s peed is restricted to 3,000 rpm, then
1,500
rpm until the oil is changed. Have
the engine oil changed to avoid any risk of
damage.
After a

few seconds, the display returns to its
usual functions.
Resetting the servicing
information
Refer to the list of checks in the
manufacturer's service schedule which
was given to you on handover of the
vehicle.
Continuous flashing of the indicator is stopped
by a
qualified workshop using a diagnostic tool,
after each service.
If you have ser viced your vehicle personally,
you must reset the ser vice indicator as follows:
F

i

nsert the ignition key into the switch,
F

t

urn it to the MAR position,
F

s
imultaneously press the brake and
accelerator pedals for more than
15

seconds.

Electronic stability control
(ESC)
Electronic stability control (ESC) integrating the
following systems:
-

a
nti-lock braking system (ABS) and
electronic brake force distribution (EBFD),
-
em

ergency braking assistance (EBA),
-

w
heel anti-slip regulation (ASR) or traction
control,
-
d

ynamic stability control (DSC).
Horn
F Press the central part of the steering wheel.
Definitions
Anti-lock braking system (ABS)
and electronic brake force
distribution (EBFD)
This system improves the stability and
manoeuvrability of your vehicle when braking
and contributes towards improved control on
corners, in particular on poor or slippery road
surfaces.
The ABS prevents wheel lock in the event of
emergency braking.
The electronic brake force distribution system
(EBFD) manages the braking pressure wheel
by wheel.
Emergency braking assistance
(EBA)
In an emergency, this system permits the
optimum braking pressure to be reached
more quickly, therefore reducing the stopping
distance.
It is triggered in relation to the speed at which
the brake pedal is pressed. The effect of this is
a reduction in the resistance of the pedal and
an increase in braking efficiency.
Anti-slip regulation (ASR)
The ASR system (also known as Traction
Control) optimises traction in order to limit
wheel slip by acting on the brakes of the driving
wheels and on the engine. It also improves
the directional stability of the vehicle on
acceleration.
Safety

69
Dynamic stability control (DSC)
If there is a difference between the path
f ollowed by the vehicle and that required by
the driver, the DSC monitors each wheel and
automatically acts on the brake of one or more
wheels and on the engine to return the vehicle
to the required path, within the limits of the laws
of physics.
Anti-lock braking system
(ABS) and electronic brake
force distribution (EBFD)
If this warning lamp comes on,
accompanied by an audible signal
and a
message in the instrument
panel screen, it indicates a
fault with
the anti-lock braking system (ABS)
which could result in loss of control
of the vehicle when braking.
If these warning lamps come on,
accompanied by a
message in the
instrument panel screen, it indicates
a
fault with the electronic brake force
distribution (EBFD) system which
could result in loss of control of the
vehicle when braking.
You must stop as soon as it is safe to do so.
In both cases, contact a
CITROËN dealer or
a


qualified workshop. For maximum braking efficiency, a
bedding-in period of around 310
miles
(500 kilometres) is needed. During this
period, it is advisable to avoid any sudden,
repeated and prolonged braking.
The ABS does not provide shorter braking
distances. On very slippery sur faces (ice,
oil, etc.) the ABS may extend braking
distances.
When changing wheels (tyres and rims),
make sure that these are approved for
your vehicle.
For emergency braking, press the
brake pedal ver y hard and do not
release it, even on a
slipper y sur face;
you will then be able to continue
steering the vehicle to avoid an
obstacle.
After an impact, have these systems
checked by a
CITROËN dealer or
a


qualified workshop.
Dynamic stability control
(DSC)
Switching on
The DSC system is activated automatically
each time the vehicle is started.
It comes into operation in the event of a grip or
trajectory problem.
This is indicated by this warning
lamp flashing in the instrument
panel.
Deactivation
This system cannot be deactivated by the
driver.
Malfunction
Illumination of this warning lamp,
accompanied by an audible signal
and confirmed by a message in the
instrument panel screen, indicates
a
fault with the DSC system.
Have it checked by a
CITROËN dealer or by
a


qualified workshop.

Intelligent Traction Control
System to improve traction on slippery sur faces
(snow, ice, mud, etc.)
This system checks for situations of difficult
sur face grip that could make it difficult to move
off or make progress.
In these situations, Intelligent Traction
Control takes over from the ASR system, by
transferring drive to the wheel with the best grip
on the ground to provide the best traction and
trajectory control.
Switching on
On starting the vehicle, this system is
deactivated.
F

P
ress this button to switch the system on;
the warning lamp in the button comes on.
This system is active up to about 19
mph
(30


km/h).
Once the speed exceeds 19
mph (30 km/h),
the system is deactivated automatically, but the
warning lamp in the button stays on. The system is reactivated automatically
as soon as the speed drops below 19
mph
(30

km/h).
Deactivation
F Press this button to deactivate the system;
the warning lamp in the button goes off and
the ASR system is active again.
Malfunction
If a fault occurs with the intelligent
t raction control, this warning lamp
comes on.
Have it checked by a
CITROËN dealer or by
a


qualified workshop.
Load inertia control
All such variations have an effect on braking,
traction, the behaviour of the vehicle when
cornering and the tendency to overturn.
The true total weight of a

commercial vehicle
can vary considerably depending on the load
carried. As a

result, the centre of gravity of the
vehicle can move, both longitudinally and in
height. Load inertia control estimates the true total
weight of the vehicle by analysing its behaviour
under acceleration and braking.
This system then adapts the operation of the
DSC and ASR systems according to the weight
distribution in the vehicle. In critical situations,
your vehicle therefore remains more securely
on its intended trajectory.
Hill Descent Control
System that provides assistance when
descending on sur faces with poor grip (mud,
gravel, etc.) or on a
steep gradient.
This system reduces the risk of slip or loss of
control of the vehicle while descending a
hill.
It keeps the vehicle at a
steady speed during
a


descent by acting independently and with
varying force on each of the brakes.
