Dynamic emergency braking
In the event of a failure of the ve-
hicle’s main braking system or in
an exceptional situation (e.g. driver
taken ill, under instruction, etc) a
continuous pull on control A will stop
the vehicle.
The electronic stability programme
(ESP) provides stability during dy-
namic emergency braking.
If the dynamic emergency braking
malfunctions, one of the following
messages will be displayed on the
m u l t i f u n c t i o n s c r e e n :
- "Parking brake faulty".
- "Parking control faulty". If a failure of the ESP sys-
tem is signalled by the ligh-
ting of this warning lamp,
then braking stability is not
guaranteed. In this event, stability
must be assured by the driver by
repeating alternate "pull release" ac-
tions on control A .
The dynamic emergency
braking must only be used in
exceptional circumstances.

Emergency unlocking In the event of the electric parking
brake malfunctioning or the battery
r u n n i n g fl a t , a n e m e r g e n c y m e c h a -
nism can unlock the parking brake.
Immobilise the vehicle, with the
e n g i n e r u n n i n g , b y e n g a g i n g fi r s t
gear (manual gearbox), posi-
tion P (automatic gearbox) or M
or R (6-speed electronic gear-
box).
Switch off the engine, but leave
the ignition on.
If the vehicle cannot be immo- bilised, do not do anything and
contact a CITROËN dealer with-
out delay.
Fetch the vehicle blocks E and
the unlocking tool F (handle)
from the toolbox.
Immobilise the vehicle by placing
blocks E at the front and at the
rear of one of the rear wheels.
Slide the front left-hand seat
back as far as possible.
L i f t u p t h e fl o o r p l u g B
on the
carpet in front of the seat.
Pierce the tab C on the tube D
with the unlocking tool F .
Place the end of the handle F in
the tube D .
Turn the unlocking tool F 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 tool F and
store it with the blocks E 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 to ol F is engaged.
Take care not to allow moisture or dust in the proximity of th e plug.

HILL START ASSIST
System which keeps your vehicle
immobilised temporarily (approxi-
mately 2 seconds) when starting on
a gradient, the time it takes to move
your foot from the brake pedal to the
accelerator pedal.
T h i s f u n c t i o n i s o n l y a c t i v e w h e n :
- 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 for a brief moment when you
release the brake pedal:
- p r o v i d e d y o u a r e i n fi r s t g e a r o r neutral on a manual gearbox,
- provided you are in A or M on an
electronic gearbox,
- provided you are in D or M on an
automatic gearbox.
On a descending slope, with the
vehicle stationary and reverse
gear engaged, the vehicle is held
for a brief moment when you re-
lease 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 ve-
hicle with the engine running,
manually apply the parking brake
and ensure that the warning lamp
P (red) on the instrument panel is
permanently on.

Acceleration
For optimum acceleration (e.g. to
overtake another vehicle), simply
press the pedal beyond the point of
resistance at the end of its travel, by
p r e s s i n g d o w n fi r m l y .
Vehicle stationary,
with the engine running
In the event of a prolonged stop with
the engine running, the gearbox
changes automatically to neutral N . Stopping the vehicle
Before stopping the engine, you can
c h o o s e :
to leave the vehicle in neutral;
move the selector to position N .
to leave the vehicle with a gear
engaged ( R , A or M ); place the
selector in the chosen position
prior to stopping the engine. In
this case, the vehicle cannot be
moved.
In all cases, it is essential to apply
the parking brake. Check that the
parking brake warning lamp is lit up
in the instrument panel.
Do not use the accelera-
tor to hold your vehicle on
a gradient. Use either the
brake pedal or the parking
brake.
Before doing anything in the en-
gine compartment, check that the
selector is in neutral N .

Brake pads Brake wear depends on
the style of driving, par-
ticularly in the case of ve-
hicles used in town, over
short distances. It may be
necessary to have the condition of
the brakes checked, even between
vehicle services.
Unless there is a leak in the circuit, a
d r o p i n t h e b r a k e fl u i d l e v e l i n d i c a t e s
that the brake pads are worn.
Manual gearbox
The gearbox does not re-
quire any maintenance (no
oil change).
6 - s p e e d e l e c t r o n i c g e a r b o x
system
The gearbox does not require any
maintenance (no oil change).
Automatic gearbox
The gearbox does not require any
maintenance (no oil change). Brake disc wear
For information relating to
checking the brake disc
wear, contact a CITROËN
dealer.
Parking brake
If a loss of effectiveness of this sys-
tem is noticed, the parking brake
must be checked, even between two
services.
This system must be checked by a
CITROËN dealer. Only use products recom-
mended by CITROËN or
products of equivalent qual-
i t y a n d s p e c i fi c a t i o n s .
In order to optimise the operation
of units as important as the braking
system, CITROËN selects and of-
f e r s v e r y s p e c i fi c p r o d u c t s .
To avoid damaging the electrical
units, the use of a high pressure
washer in the engine compartment
is strictly prohibited .
