Switch off the headlamps and front
foglamps when the level of light does
not require their use.

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 (fi lm, music,
video game...), you will contribute to-
wards limiting the consumption of elec-
trical energy, and so of fuel.
Disconnect your portable devices be-
fore leaving the vehicle.



Limit the causes of excess
consumption

Spread loads throughout the vehicle;
place the heaviest items in the bottom
of the boot, as close as possible to the
rear seats.
Limit the loads carried in the vehicle
and reduce wind resistance (roof bars,
roof rack, bicycle carrier, trailer...). Use
a roof box in preference.
Remove roof bars and roof racks after
use.

At the end of winter, remove snow
tyres and refi t your summer tyres.



Observe the recommendations
on maintenance

Check the tyre pressures regularly,
when cold, referring to the label in the
door aperture, driver's side.
Carry out this check in particular:


- before a long journey,

- at each change of season,

- after a long period out of use.
Don't forget the spare wheel and the
tyres on any trailer or caravan.

Have your vehicle serviced regularly
(engine oil, oil fi lter, air fi lter...) and ob-
serve the schedule of operations rec-
ommended by the manufacturer.



When refuelling, do not continue after
the third cut-off of the nozzle to avoid
any overfl ow.


At the wheel of your new vehicle, it is only
after the fi rst 1 800 miles (3 000 kilometres)
that you will see the fuel consumption set-
tle down to a consistent average.

Service


temporarily,
accompanied by
a message. A minor fault has occurred
for which there is no specifi c
warning lamp. Identify the problem by reading the
message displayed in the screen, such
as, for example:


- the opening of the doors, boot or
bonnet,

- the engine oil level,

- the remote control battery,

- a fault with the tyre pressure
monitoring system.
For any other malfunctions, contact a
CITROËN dealer or a qualifi ed workshop.

fi xed,
accompanied by
a message and
an audible signal. A major fault has occurred
for which there is no specifi c
warning lamp. Identify the fault by reading the message
displayed in the screen and contact a
CITROËN dealer or a qualifi ed workshop.

fi xed. The brake pedal is not
pressed. With an electronic gearbox, press the
brake pedal to start the engine (lever in

If you wish to release the parking brake
without pressing the brake pedal, this
warning lamp will remain on.

fl ashing. With an electronic gearbox,
if you hold the vehicle on
a rising incline using the
accelerator for too long, the
clutch overheats. Use the brake pedal and/or the electric
parking brake.

wheels is too low. Check the pressure of the tyres as soon
as possible.
This check should preferably be carried
out when the tyres are cold.

SAFETY

BRAKING ASSISTANCE
SYSTEMS
Group of supplementary systems which
help you to obtain optimum braking in
complete safety in emergency situa-
tions:


- anti-lock braking system (ABS),

- electronic brake force distribution
(EBFD),

- emergency braking assistance (EBA).

When braking in an emergency,
press very fi rmly without releas-
ing the pressure.
When replacing wheels (tyres
and rims), ensure that they con-
form to the manufacturer's rec-
ommendations.
When braking in an emergency,
press fi rmly without releasing
the pressure.



Anti-lock braking system
and electronic brake force
distribution
Linked systems which improve the sta-
bility and manoeuvrability of your vehi-
cle when braking, in particular on poor
or slippery surfaces.

Activation
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.
Operating fault
If this warning lamp comes on,
accompanied by an audible
signal and a message in the
screen, it indicates a malfunc-
tion of the anti-lock braking system
which could result in loss of control of
the vehicle when braking.
If this warning lamp comes on,
together with the STOP
and
ABS
warning lamps, accompa-
nied by an audible signal and
a message in the screen, it indicates a
malfunction of the electronic brake force
distribution which could result in loss of
control of the vehicle when braking.

You must stop as soon as it is safe
to do so.











Emergency braking assistance

System which, in an emergency, en-
ables you to obtain the optimum braking
pressure more quickly, thus reducing
the stopping distance.

Activation
It is triggered by 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 effi ciency.
In either case, contact a CITROËN
dealer or a qualifi ed workshop.

DRIVING

TYRE UNDER-INFLATION
DETECTION

System which automatically checks the
pressures of the tyres while driving.
The system continuously monitors the
pressures of the four tyres, as soon as
the vehicle is moving.
A pressure sensor is located in the
valve of a each tyres (except the spare
wheel).
The system triggers an alert if a drop
in pressure is detected in one or more
tyres.
The tyre under-infl ation detection sys-
tem is an aid to driving which does not
replace the need for the driver to be
vigilant or to drive responsibly.
This system does not avoid the
need to check the tyre pressures
regularly (including the spare
wheel) and before a long jour-
ney.
Driving with under-infl ated tyres
adversely affects road holding,
extends braking distances and
causes premature tyre wear,
particularly under arduous con-
ditions (vehicle loaded, high
speed, long journey).

Driving with under-infl ated tyres
increases fuel consumption.
The tyre pressures for your vehi-
cle can be found on the tyre pres-
sure label (see the "Identifi cation
markings" section).
The tyre pressures must be
checked when the tyres cold
(vehicle stopped for 1 hour or
after driving for less then 6 miles
(10 km) at moderate speed).
Otherwise, add 0.3 bar to the val-
ues indicated on the label.

DRIVING
167
The fl ashing and then fi xed
illumination of the under-infl a-
tion warning lamp accompa-
nied by the illumination of the
"service" warning lamp indi-
cates a fault with the system.

Operating fault

The alert is given by the fi xed il-
lumination of this warning lamp,
accompanied by an audible sig-
nal, and depending on equip-
ment, the display of a message.

Under-inflation alert


The alert is maintained until the
tyre or tyres concerned is rein-
fl ated or repaired.

The loss of pressure detected
does not always lead to visible
deformation of the tyre. Do not
rely on just a visual check.

This alert is also displayed when
one or more wheels is not fi tted
with a sensor.
In the event of a problem on one of
the tyres, the symbol or the message
appears, according to equipment, to
identify it.


Reduce speed, avoid sudden steer-
ing movements or harsh brake ap-
plications.


Stop as soon as it is safe to do so.


In the event of a puncture, use the
temporary puncture repair kit or the
spare wheel (according to equip-
ment),
or


if you have a compressor, the one in
the temporary puncture repair kit for
example, check the four tyre pres-
sures when cold,
or


if it is not possible to check the tyre
pressures at the time, drive care-
fully at reduced speed. In this case, monitoring of the tyre pres-
sures is not assured.
Have the system checked by a
CITROËN dealer or a qualifi ed work-
shop.

TEMPORARY PUNCTURE
REPAIR KIT

Access to the kit


The speed limit sticker I
must be
affi xed to the vehicle's steering
wheel to remind you that a wheel
is in temporary use.
Do not exceed a speed of
50 mph (80 km/h) when driving
with a tyre repaired using this
type of kit.
This kit is installed in the storage box,
under the boot fl oor.

A.
"Sealant" or "Air" position selector.

B.
On "I"
/ off "O"
switch.

C.
Defl ation button.

D.
Pressure gauge (in bar and p.s.i.).

E.
Compartment housing:


- a cable with adaptor for 12 V
socket,

- various infl ation adaptors for ac-
cessories, such as balls, bicycle
tyres...


Description of the kit


F.
Sealant cartridge.

G.
White pipe with cap for repair.

H.
Black pipe for infl ation.

I.
Speed limit sticker.
Complete system consisting of a com-
pressor and a sealant cartridge which
permits temporary repair
of a tyre so
that you can drive to the nearest ga-
rage.
It is designed to repair most punctures
which could affect the tyre, located on
the tyre tread or shoulder.



The vehicle's electric system al-
lows the connection of a com-
pressor for long enough to infl ate
a tyre after a puncture repair or
for infl ating a small infl atable ac-
cessory.
