TRAJECTORY CONTROL SYSTEMS
Anti-skid regulation (ASR) and
electronic stability programme
(ESP)
The anti-skid regulation optimises
traction to prevent skidding of the
wheels, by acting on the brakes of
the driving wheels and on the engine.
The electronic stability programme
acts on the brake of one or more
wheels and on the engine to keep
the vehicle on the trajectory required
by the driver.
Activation
These systems are activated auto-
matically each time the vehicle is
started.
They come into operation in the
event of a grip or trajectory problem. This is indicated by fl ashing
of this warning light on the
instrument panel. Disarming
In exceptional conditions (starting a
vehicle which is bogged down, stuck
in snow, on soft ground, ...), it may
be advisable to disarm the ASR and
ESP systems, so that the wheels
can move freely and regain grip.

 Press the "ESP OFF" button, lo-
cated in the centre of the fascia. Reactivation
These systems are reactivated au-
tomatically each time the ignition is
switched back on or from 30 mph
(50 km/h).


Press the "ESP OFF" button again
to reactivate them manually.
If this warning light comes
on on the instrument panel
and the indicator light on the
button comes on, this indi-
cates that the ASR and ESP
systems are disarmed. Operating fault
If this warning light comes
on, accompanied by an au-
dible signal and a message
on the multifunction display,
this indicates a malfunction
of these systems.
Have the systems checked by a
CITROËN dealer.
The ESP/ASR systems offer ex-
ceptional safety in normal driving,
but this should not encourage the
driver to take extra risks or drive at
high speed.
The correct functioning of these
systems depends on observation
of the manufacturer’s recommen-
dations regarding the wheels (tyres
and rims), the braking components,
the electronic components and the
CITROËN assembly and operation
procedures.
After an impact, have these systems
checked by a CITROËN dealer.

AIR BAGS
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 air bags are triggered instant-
ly and protect the occupants of
the vehicle (with the exception of
the rear centre passenger); im-
mediately after the impact, the
air bags defl ate rapidly so that
they do not hinder visibility or the
exit of the occupants,
- in the case of a minor or rear im- pact or in certain roll-over con-
ditions, the air bags will not be
triggered; the seat belt alone is
suffi cient to provide optimum
protection in these situations.
The air bags do not operate
when the ignition is switched
off.
This equipment will only operate
once. If a second impact occurs
(during the same or a subsequent
accident), the air bag will not operate. Impact detection zones

A. Front impact zone.

B. Side impact zone.
Triggering of the air bag(s) is ac-
companied by a slight emission of
harmless 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 air bags
System which protects the head and
chest of the driver and front passen-
ger in the event of a front impact.
The driver's air bag is incorporated
in the centre of the steering wheel;
the front passenger's air bag is in-
corporated in the fascia above the
glove box.
Activation
The air bags are triggered simultane-
ously, unless the passenger's front
air bag is disarmed, in the event of
a serious front impact applied to all
or part of the front impact zone
A ,
in the longitudinal centreline of the
vehicle on a horizontal plane and di-
rected from the front to the rear of
the vehicle.
The front air bag infl ates between
the front occupant of the vehicle and
the fascia to cushion his forward
movement.

125

S A F E T Y
For the air bags to be fully
effective, observe the following
safety rules:
Sit in a normal upright position.
Wear a correctly adjusted seat belt.
Do not leave anything between the
occupants and the air bags (a child,
pet, object...). This could hamper the
operation of the air bags or injure the
occupants.
After an accident or if the vehicle
has been stolen or broken into, have
the air bag systems checked.
All work on the air bag system is
strictly forbidden unless it is carried
out by qualifi ed personnel of the
CITROËN network.
Even if all of the precautions men-
tioned are observed, a risk of injury
or of minor burns to the head, chest
or arms when an air bag is triggered
cannot be ruled out. In fact, the bag
infl ates almost instantly (within a few
milliseconds) then defl ates within
the same time discharging the hot
gas via openings provided for this
purpose. Front air bags
Do not drive holding the steering
wheel by its spokes or resting your
hands on the centre part of the
wheel.
Passengers must not place their feet
on the fascia.
Smoke as little as possible as de-
ployment of the air bags can cause
burns or the risk of injury from a ciga-
rette or pipe.
Never remove or pierce the steering
wheel or hit it violently.
Side air bags
Put approved covers only on the
seats. These will not hinder infl a-
tion of the side air bags. Consult a
CITROËN dealer.
Do not fi x or glue anything to the
seat backs. This could cause injury
to the chest or arms if the side air
bag is triggered.
Do not sit with the upper part of the
body any nearer to the door than
necessary. Curtain air bags
Do not fi x or glue anything to the roof.
This could cause injury to the head if
the curtain air bag is triggered.
Do not remove the grab handles in-
stalled on the roof, they play a part
in securing the curtain air bags.

Release
With the ignition on or the engine run-
ning, to release the parking brake,
press on the brake pedal, pull then
release control A .
The full application of the parking
brake is confi rmed by: - the extinction of the warn-ing lamp on control A and
of warning lamp P on the
instrument panel,
- the display of a message "park- ing brake released" on the multi-
function screen.
If you pull control A without pressing
the brake pedal, the parking brake
will not be released and the "Foot on
brake" warning lamp will light up on
the instrument panel.
When stationary, with the
engine running, do not
press the accelerator pedal
unnecessarily, as you may release
the parking brake. Maximum application
If necessary, you can utilise
maxi-
mum application of the parking
brake. It is obtained by means of
a long pull on control A , until you
see the message "parking brake ap-
plied" and a beep is heard.

Maximum application is essential:
- in the case of a vehicle towing a caravan or a trailer, if the au-
tomatic functions are activated
but you are applying the parking
brake manually,
- when the gradient you are parked on is variable in its effect (e.g. on
a ferry, in a lorry, during towing),
- in the case of towing, a loaded vehicle or parking on a gradient,
turn the front wheels towards the
pavement and engage a gear
when you park,
- after a maximum application, the release time will be longer. Particular situations
In certain situations (e.g. starting
the engine), the parking brake can
automatically alter its force. This is
normal operation.
To advance your vehicle a few cen-
timetres without starting the engine,
but with the ignition on, press on the
brake pedal and release the park-
ing brake
by pulling then releasing
control A .
The full release of the parking brake
is confi rmed by the extinction of
warning lamp P (red) on the instru-
ment panel and the display of a
message "parking brake released"
on the multifunction screen.
If the parking brake malfunctions

while applied or if the battery runs
fl at, an emergency release is always
possible.

Emergency unlocking In the event of the electronic parking
brake malfunctioning or the battery
running fl at, an emergency manual
device can unlock the parking brake.

 Immobilise the vehicle, with the
engine running, by engaging fi rst
gear (manual gearbox), position

P (automatic gearbox) or M or

R (6-speed electronic gearbox),
then switch off the engine.
If it is impossible to immobilise the vehicle, do not action the
control and urgently contact a
CITROËN dealer.

 Fetch the vehicle blocks and the
unlocking device (braided cable)
from the toolbox.

 Immobilise the vehicle by plac-
ing blocks at the front and at the
rear of one of the rear wheels.

 Slide the front left-hand seat
back as far as possible.

 Lift up the fl oor plug B in the car-
pet under the seat.
 Pierce the tab C on the tube D
with the unlocking device.

 Place the unlocking device in the
tube D .

 Turn the unlocking device clock-
wise. For safety reasons
, it is

essential to continue turning the
device as far as it will go or until
you hear a knocking noise. The
parking brake is released.

 Remove the unlocking device
and store it with the blocks in the
toolbox.
- The operation of the parking brake reinitialises when the ig-
nition is switched off then on
again. If the reinitialisation of the
parking brake proves impossi-
ble, contact a CITROËN dealer.
- The subsequent time required for application may be longer
than during normal operation.
For safety reasons, after this manoeuvre it is essential to cont act a CITROËN dealer urgently to have the plug
replaced.
Following an emergency unlocking, immobilisation of the vehi cle is no longer guaranteed once the manual emer-
gency unlocking has been deployed and the manual control doe s not allow the re-application of your parking
brake.
Take no action, either on control A , or stopping starting the engine while the unlocking de vice is engaged.
Take care not to allow moisture or dust in the proximity of th e plug.

Operation in manual mode

 Move the selector to po-
sition M .

Controls under the steering
wheel
The levers under the steering wheel
give you access to the six forward
gears. Changing gear

 Pull the lever " + " to change up a
gear.

 Pull the lever " - " to change down
a gear. The levers do not permit you to se-
lect neutral or reverse gear, or to exit
reverse gear.
- If the vehicle stops or reduces
speed (for example when ap-
proaching a stop sign), the gear-
box changes down automatically
to fi rst gear.
- In manual mode, it is not neces- sary to release the accelerator
completely during gear changes.
- A request to change gear is ac- cepted only if the engine speed
permits it.
- For safety reasons, depending on the engine speed, a change
down may be performed auto-
matically.
In situations of high engine
speeds (heavy acceleration),
a change up will not occur
unless the driver actions this
on the lever controls.

 When the engine is running,
place the selector on R , D or M
as required.

 Check, in the instrument panel,
the position engaged.

 Release the brake pedal and ac-
celerate.

 If the selector is not in position P ,
a message "place automatic
gear-box in position P " appears
on the multifunction screen, ac-
companied by a beep and the
fl ashing of P on the instrument
panel.
Moving off

 To avoid incoherence between
the position of the selector and
the actual position of the gear-
box, always exit from position P
when you switch on the ignition
and press the brake pedal.
Otherwise, when the ignition is on or
the engine is running:

 reposition the selector in posi-
tion P ,

 put your foot on the brake pedal
and then select the gear you
want.

 To select position P, move the
selector back to the highest po-
sition (towards R ), then push it
forwards and then to the left.

 To exit position P , move the se-
lector to the right and then to the
position you want.

 Only engage this position when
the vehicle is completely sta-
tionary. In this position, the front
wheels are locked. Make sure
that the selector is correctly posi-
tioned. Reverse gear
Neutral
Only engage this position
when the vehicle is station-
ary. To prevent snatching,
do not accelerate too soon
after selection.
Never select position
N if
the vehicle is moving.
Never select positions P or

R if the vehicle is not sta-
tionary.
If, while the vehicle is moving, po-
sition N is engaged inadvertently,

SPEED LIMITER
System which prevents the vehi-
cle from exceeding the speed pro-
grammed by the driver.
Once the limit speed has been
reached, the accelerator pedal no
longer has any effect.
The speed limiter is switched
on manually: a speed of at least
30 km/h (around 20 mph) must be
programmed.
The speed limiter controls are located
on the left-hand side of the steering
wheel. The programmed information is
grouped together in zone
A of the
instrument panel display.
Steering wheel controls Displays on the instrument
panel
Programming
Rotate the control
1 to the "LIM" po-
sition. With the engine running, you can
adjust the memorised maximum
speed , by means of short or long
presses on:

 button 4 to increase the memo-
rised maximum speed,

 button 2 to decrease the memo-
rised maximum speed.
Successive presses will modify the
maximum speed in steps of 1 mph
and a sustained press in steps of
3 mph.
Activation
When the desired maximum speed
is displayed, press button 3 so that
the limitation is activated.
On selection of the
function, the previous
memorised speed and
the information "OFF"
are displayed: The information
"OFF"
then disappears from
the instrument panel
display.
While the function is active, press-
ing the accelerator pedal will not en-
able the programmed speed to be
exceeded, except if you press the
pedal hard down to beyond the end-
of-travel switch.
The speed of your vehicle may vary
slightly in relation to that memo-
rised.
The speed limiter cannot, in any
circumstances, take the place of
the observance of speed limits or
of the vigilance and responsibility
of the driver.
