AIRBAGS
System designed to maximise the
safety of the occupants (with the
exception of the rear centre pas-
senger) in the event of violent col-
lisions. It supplements the action of
the force-limiting seat belts.
If a collision occurs, the electronic
detectors record and analyse the
front and side impacts sustained in
the impact detection zones:
- in the case of a serious impact, the airbags are triggered instant-
ly and protect the occupants of
the vehicle (with the exception
of the rear centre passenger);
immediately after the impact, the
airbags defl ate rapidly so that
they do not hinder visibility or the
exit of the occupants,
- in the case of a minor or rear impact or in certain roll-over
conditions, the airbags will not
be triggered; the seat belt alone
is suffi cient to provide optimum
protection in these situations.
The airbags do not operate when
the ignition is switched off.
This equipment will only operate
once. If a second impact occurs (dur-
ing the same or a subsequent acci-
dent), the air bag will not operate. Impact detection zones

A. Front impact zone.

B. Side impact zone.
Triggering of the air bag(s) is accom-
panied by a slight emission of harm-
less smoke and a noise, due to the
activation of the pyrotechnic cartridge
incorporated in the system.
This smoke is not harmful, but sen-
sitive individuals may experience
slight irritation.
The noise of the detonation may
result in a slight loss of hearing for
a short time. Front airbags
System which protects the head and
chest of the driver and front passen-
ger in the event of a front impact.
The driver’s airbag is incorporated
in the centre of the steering wheel;
the front passenger’s airbag is incor-
porated in the dashboard above the
glove box.
Operation
The airbags are triggered simultane-
ously, unless the passenger’s front
airbag is deactivated, in the event of
a serious front impact to all or part of
the front impact zone
A , in the lon-
gitudinal centreline of the vehicle on
a horizontal plane and directed from
the front to the rear of the vehicle.
The front airbag infl ates between
the front occupant of the vehicle and
the fascia to cushion their forward
movement.

HILL START ASSIST (WITH THE 6-SPEED ELECTRONIC GEARBOX SYSTEM)
System which holds your vehicle tem-
porarily (approximately 2 seconds)
when starting on a gradient, the time it
takes to move your foot from the brake
pedal to the accelerator pedal.
This function is only active when:
- the vehicle is completely station-ary, with your foot on the brake
pedal,
- in particular conditions on a slope,
- with the driver’s door closed.
The hill start assist function cannot
be deactivated. Operation
Operating fault
If a malfunction of the system oc-
curs, these warning lamps come on.
Contact a CITROËN dealer to have
the system checked.

On an ascending slope, with the
vehicle stationary, the vehicle is
held
momentarily
when you re-
lease the brake pedal:
- provided you are in A or M on an
electronic gearbox,
On a descending slope, with the
vehicle stationary and reverse
gear engaged, the vehicle is held

momentarily
when you release
the brake pedal.
do not exit the vehicle while
it is being held in the hill
start assist phase.
If you need to exit the vehi-
cle with the engine running, manu-
ally apply the parking brake and
ensure that the warning lamp P
(red) on the instrument panel is
permanently on.

CRUISE CONTROL
System which automatically main-
tains the vehicle speed programmed
by the driver, without any action on
the accelerator pedal.
The cruise control is switched on
manually: the vehicle speed must be
at least 25 mph (approx. 40 km/h)
and you must engage:
- fourth gear on a manual gearbox,
- second gear, in sequential mode, on an electronic gearbox or
automatic gearbox,
- position A on an electronic
gearbox or D on an automatic
gearbox.
The cruise control cannot, in any
circumstances, take the place of the
observance of speed limits or of the
vigilance and responsibility of the
driver. Steering wheel controls
The cruise control switches are
located on the left-hand side of the
steering wheel.
Displays on the instrument panel
The programmed information is
grouped together in zone
A of the
instrument panel display. Programming
Rotate the control
1 to the "REG"
position.
Activation
On selection of the function via con-
trol 1, no cruise speed has yet
been memorised.
Once the desired speed has been
reached using the accelerator, press
button 2 or button 4 . The cruise
speed is then memorised. It is dis-
played in zone A of the instrument
panel.
You can then release the accelera-
tor pedal. The vehicle will automati-
cally keep to the speed chosen.
The speed of your vehicle may vary
slightly in relation to that memo-
rised.
You can adjust the memorised speed
on the instrument panel display by
pressing on:

 button 4 to increase the speed,

 button 2 to decrease the speed.
Successive presses modify the
cruise speed in steps of 1 mph and a
sustained press in steps of 3 mph.

Deactivation

 Either by pressing on the brake
pedal or on the clutch pedal.

 Or by pressing button 3 .

 Or if either the ESP or the ASR
system is active.
The cruise control is not active if the
gear lever is in neutral.
These actions cause the information

"OFF" to appear on the instrument
panel display.
These actions do not cancel the
cruise speed which remains dis-
played in the instrument panel.
Reactivation

 By recall of the memorised
speed
After a disengagement, press on button 3 . Your vehicle automati-
cally returns to the memorised
cruise speed which is displayed
in zone A .
If the memorised cruise speed is higher than the current speed,
the vehicle will accelerate to
reach the former.

 By selection of the current
speed
Press on button 2 or 4 once the
desired speed has been reached.
The information "OFF" will then
disappear from the instrument
panel display. Overriding the programmed
speed
During the operation of cruise con-
trol, it is always possible to use the
accelerator to go faster than the
cruise speed (for example to over-
take another vehicle). The speed
displayed in zone
A fl ashes.
You have only to release the acce-
lerator pedal to return to the cruise
speed.
Return to normal driving

 By an action on the control 1 from
position "REG" to position 0 .

 By the engine stopping.
The cruise speed previously chosen
is no longer memorised. Operating fault
If there is a malfunction, a message
will display accompanied by an
audible signal and lighting of the
service warning lamp.
Have it checked by a CITROËN
dealer.
If during the operation of cruise
control, the system is unable to
keep within the memorised speed
(for example on a steep descent),
then the speed fl ashes. Adapt your
speed as necessary. Cruise control should only be used
when the driving conditions allow
you to drive at a constant speed.
Do not use it in heavy traffi c, or on
dangerous or slippery roads.
The driver must remain attentive
and in full control of his vehicle.
You are recommended to keep your
feet within range of the pedals.
To avoid any risk of interfering with
the pedals:
- check that the fl oor mat is cor-
rectly positioned,
- never use more than one fl oor mat.

LANE DEPARTURE WARNING SYSTEM
System which detects the involun-
tary crossing of longitudinal traffi c
lane markings on the ground (solid
or broken line).
Sensors, fi tted below the front
bumper, trigger a warning if the vehi-
cle drifts over a lane marking (speed
higher than 50 mph (80 km/h)).
This system is particularly useful on
motorways and main roads. Activation

 Press button A , the indicator
lamp comes on.
Deactivation

 Press button A again, the indica-
tor lamp switches off.
The status of the system remains
in the memory when the ignition is
switched off.
Detection
You are warned by the vibration of
the driver's seat cushion:
- on the right-hand side, if the marking on the ground has been
crossed on the right,
- on the left-hand side, if the mark- ing on the ground has been
crossed on the left.
No warning is transmitted while the
direction indicator is active and for
approximately 20 seconds after the
direction indicator is switched off.
A warning may be transmitted if a
direction marking (e.g. arrow) or
non-standard marking (e.g. graffi ti)
is crossed. Operating fault
In the event of a malfunction, the
service warning lamp comes on,
accompanied by an audible signal
and a message on the multifunction
screen.
Consult a CITROËN dealer.
The lane departure warning sys-
tem cannot, in any circumstances,
replace the need for vigilance and
responsibility on the part of the
driver. The detection may be impeded:
- if the sensors are dirty (mud,
snow...),
- if the markings on the ground are worn,
- if there is little contrast between the markings on the ground and
the road surface.

VISUAL AND AUDIBLE FRONT AND/OR REAR PARKING ASSISTANCE
System consisting of four proximity
sensors, installed in the front and/or
rear bumper.
It detects any obstacle (person, ve-
hicle, tree, barrier...) located behind
the vehicle, however, it will not be
able to detect obstacles located im-
mediately below the bumper.
An object, such as a stake, a road-
works cone or any other similar ob-
ject may be detected at the start of
the manoeuvre but may no longer
be detected when the vehicle moves
nearer to it. The parking assistance is
switched
off :
- when you exit reverse gear,
- when the speed is higher than 6 mph (10 km/h) in forward
gear,
- when the vehicle has been sta- tionary for more than three sec-
onds in forward gear.
The parking assistance system
cannot, in any circumstances, re-
place the need for vigilance and
responsibility on the part of the
driver.
The parking assistance is
switched
on :
- by engaging reverse gear,
- at a speed below 6 mph (10 km/h) in forward gear.
This is accompanied by an audible
signal and/or displaying of the vehi-
cle on the multifunction screen.
The proximity information is indicated
by:
- an audible signal which be- comes more rapid as the vehicle
approaches the obstacle,
- a diagram on the multifunction screen, with blocks which move
closer to the vehicle.
The obstacle is located in relation to
the emission of the audible signal by
the speakers; front or rear and right
or left.
When the distance between the ve-
hicle and the obstacle is less than
approximately thirty centimetres, the
audible signal becomes continuous
and/or the "Danger" symbol appears,
depending on the multifunction screen
version.

122
D R I V I N G
In bad weather or in winter, ensure
that the sensors are not covered
with mud, ice or snow. When re-
verse gear is engaged, an audible
signal (long beep) indicates that
the sensors may be dirty.
When the vehicle is being driven
at a speed below approximately
6 mph (10 km/h), certain sourc-
es of noise (motorcycles, lorries,
pneumatic drills, ...) may trigger the
reversing audible signal.
Reactivation

 Press button A again, the warning
lamp switches off, the system is
reactivated.
Deactivation Operating fault
If an operating fault occurs, this warn-
ing lamp is displayed on the instrument
panel and/or a message appears on
the multifunction screen, accompa-
nied by an audible signal (short beep),
when reverse gear is engaged.
Consult a CITROËN dealer.

 Press button A , the warning lamp
comes on, the system is fully de-
activated.
The system will be deactivated au-
tomatically when a trailer is being
towed or when a bicycle carrier is
fi tted (vehicle fi tted with a towbar
or bicycle carrier recommended by
CITROËN).

RUNNING OUT OF FUEL (DIESEL)
HDi 135 and 140 engine
Detach the protection cover to gain
access to the priming pump. HDi 90 and 110 engine
Detach the protection cover to gain
access to the priming pump. Priming the fuel circuit
In the event of running out of fuel:

 after fi lling (minimum 5 litres),
squeeze the manual priming
pump repeatedly, until some re-
sistance is felt,

 then operate the starter, gently
pressing the accelerator until the
engine starts.
If the engine fails to start at the fi rst
attempt, wait 15 seconds before try-
ing again.
If the engine fails to start after a few
attempts, repeat the procedure from
the beginning. When the engine is
idling, accelerate gently to complete
the purge of the circuit.
HDi engines are of a highly
technical nature.
All maintenance and re-
pairs require specifi c qualifi cations
which only your CITROËN dealer
can guarantee.
