Dynamic emergency braking
In the event of a failure of the vehicle’s
main braking system or in an excep-
tional situation (e.g. driver taken ill,
under instruction, etc) a continuous
pull on the control lever 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
multifunction screen:
- "Parking brake faulty".
- "Parking brake control faulty". If a failure of the ESP sys-
tem is signalled by the light-
ing 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"
actions 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
running fl at, an emergency mecha-
nism 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).

 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.
 Lift up the fl oor plug 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 igni-
tion is switched off then on again.
If the reinitialisation of the park-
ing brake proves impossible,
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 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 stationary, 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:
- provided you are in fi rst gear or 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 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.

Displays on the instrument panel
- The selector position is displayed in the instrument panel, on the
left on multifunction screens A
and C and on the right on the
NaviDrive multifunction screen.
- A background-lit position grille as- sociated with the selector allows
you to view the position selected.

When the ignition is on,
lighting of the service
warning lamp, accompa-
nied by an audible signal and
the message "Gearbox faulty"
indicates a malfunction.
Consult a CITROËN dealer.
For safety:

 Position N can only be disen-
gaged if you are pressing the
brake pedal.

 If the gearbox is in position N
but the selector position is differ-
ent, reposition the selector on N
in order to be able to start. Moving off

 To start the engine, the selector
must be in position N .

 Press fi rmly on the brake pedal.

 Operate the starter.

 When the engine is running,
place the selector on R , A or M
as desired.

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

 Release the brake pedal and ac-
celerate.
If the selector is not in position N ,
and/or if the brake pedal is not
pressed, the corresponding warning
lamp(s) are displayed and a mes-
sage informs you that at least one of
these two conditions is not met.
In this case, the engine will not start,
recommence the above procedure. Reverse gear

Engaging reverse gear
To engage reverse gear, move the
selector to R .

Only attempt to select reverse gear
when the vehicle is stationary.
If the vehicle is moving rapidly, if an in-
advertent attempt to engage reverse
gear is made, the warning lamp N will
fl ash and your vehicle will go auto-
matically into neutral. To re-engage a
gear, you have only to reposition the
selector on A , M or R .
Neutral
Changing to neutral
To change to neutral, move the se-
lector to N . If the vehicle is moving,
do not select this position even mo-
mentarily.

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
pressing down fi rmly.
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
choose:

 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 on 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 .

AUTOMATIC GEARBOX
Automatic gearbox which offers a
choice between the ease of fully
automatic operation or the driving
pleasure of manual gear changing.
Therefore, you have a choice of two
driving modes:
- automatic operation for elec-
tronic control of the gears by the
gearbox,
- manual operation for sequen-
tial changing of the gears by the
driver.

 automatic mode: selector 1 in
position D ,

 sequential mode: selector 1 in
position M . The position of the selector is dis-
played on the instrument panel, on
the left on multifunction screens
A
and C , on the right on the NaviDrive
multifunction screen.
A position grille relating to the selec-
tor allows you to view the position
that is selected. For safety:
- position
P can be disen-
gaged only if you press
the brake pedal,
- when a door is opened, a sound signal is heard if the selector is
not in position P ,
- always make sure that the se- lector is in position P before
you leave your vehicle.
If the gearbox is in position P but
the position of the selector is differ-
ent, reposition the selector on P so
that you can start the vehicle.
Never press the brake and acelera-
tor pedals simultaneously. Braking
and acceleration should be done
only with the right foot. Pressing both
pedals simultaneously introduces a
risk of damage to the gearbox.
