Dynamic emergency braking
In the event of a failure of the vehi-
cle’s main braking system or in an
exceptional situation (e.g. driver tak-
en ill, under instruction, etc) pull and
hold control A to 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
instrument panel display:
- "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" ac-
tions on control A .
The dynamic emergency
braking must only be used in
exceptional circumstances. Emergency parking brake
release
In the event of the electric parking
brake failing to release, an emer-
gency device can be used to release
the parking brake manually, provid-
ed that it is possible to immobilise
the vehicle while the procedure is
carried out.

 If you can start the vehicle: with
the engine running, immobilise
the vehicle by applying the foot
brake while the operation is be-
ing carried out.

 If you are unable to start the ve-
hicle (fl at battery for example): do
not use this device and contact
a CITROËN dealer. However, if
you are obliged to proceed, fi rst
immobilise your vehicle securely
and then follow the instructions
below.
If the vehicle cannot be im-
mobilised, do not operate
the emergency release. Your ve-
hicle may run away on any slope.
Consult a CITROËN dealer.

HILL START ASSIST
System which keeps your vehicle
immobilised temporarily (approxi-
mately 2 seconds) when starting on
a gradient, the time to move your
foot from the brake pedal to the ac-
celerator pedal.
This function is only active when:
- the vehicle is completely station-ary, with your foot on the brake
pedal,
- in certain conditions on a gradient,
- with the driver’s door closed.
The hill start assist function cannot
be deactivated. Operation

On an ascending gradient, 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 D or M on an
automatic gearbox.
On a descending gradient, 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 leave the vehicle with
the engine running, apply the park-
ing brake manually and ensure that
the parking brake warning lamp (in
the instrument panel) is on fi xed
(not fl ashing).

GEAR SHIFT INDICATOR *
System which reduces fuel con-
sumption by advising the driver to
change up on vehicles fi tted with a
manual gearbox.
Operation
The system intervenes only when
driving economically.
Depending on the driving situation
and your vehicle's equipment, the
system may advise you to skip one
or more gears. You can follow this
instruction without engaging the in-
termediate gears.
The gear engagement recommen-
dations must not be considered
compulsory. In fact, the confi gu-
ration of the road, the amount of
traffi c and safety remain determin-
ing factors when choosing the best
gear. Therefore, the driver remains
responsible for deciding whether or
not to follow the advice given by the
system.
This function cannot be deactivated.
* According to engine. Example:
- You are in third gear.
- You press the accelerator pedal
moderately.
- The system may suggest that you engage a higher gear, if ap-
propriate. The information appears in the in-
strument panel screen in the form of
an arrow accompanied by the sug-
gested gear.
In the case of driving which
makes particular demands on
the performance of the engine
(fi rm pressure on the accelerator
pedal, for example, when overtak-
ing...), the system will not recom-
mend a gear change.
The system never suggests:
- engaging fi rst gear,
- engaging reverse gear,
- engaging a lower gear.

Manual gear changing
This selective gear change mode
enables you to overtake, for exam-
ple, while still remaining in automat-
ic mode.

 Operate the + or - steering
mounted control paddle.
The gearbox engages the gear re-
quested if the engine speed per-
mits.
After a few moments without any
action on the controls, the gearbox
resumes automatic control of the
gears.

 Select position A .
The gearbox continuously selects
the most suitable gear, depending
on the:
- style of driving,
- profi le of the road.
- vehicle loading.
Automatic operation
For optimum acceleration, for example
when overtaking another vehicle, press
the accelerator pedal fi rmly past the
point of resistance.

 Select position M .
Manual operation
On sharp acceleration, the gear-
box will not change up unless the
driver acts on the gear lever or the
steering mounted paddles.
Never select neutral
N while the
vehicle is moving.
Only engage reverse gear R when
the vehicle is immobilised with the
brake pedal pressed.
The gear change requests are only
carried out if the engine speed per-
mits.
It is not necessary to release the ac-
celerator during gear changes.
When braking or slowing down, the
gearbox changes down automati-
cally to allow vehicle to accelerate in
the correct gear.
The
SPORT programme is inopera-
tive with sequential operation.

When immobilising the ve-
hicle, with the engine running,
you must place the gear lever
in neutral N .
Before carrying out any work in the
engine compartment, check that
the gear lever is in neutral N and
that the parking brake is applied.
SPORT programme Stopping the vehicle
Before switching off the engine, you
can choose to:
- move to position N to engage
neutral,
- leave the gear engaged; in this case, it will not be possible to
move the vehicle.
In both cases, you must apply the
parking brake to immobilise the ve-
hicle. Operating fault
With the ignition on, the fl ashing of

AUTO , accompanied by an audible
signal and a message on the mul-
tifunction screen, indicates a mal-
function of the gearbox.
Have it checked by a CITROËN
dealer.

STOP & START
The Stop & Start system puts the en-
gine temporarily on standby - STOP
mode - during stops in the traffi c
(red lights, traffi c jams, or other...).
The engine restarts automatically -
START mode - as soon as you want
to move off. The restart takes place
instantly, quickly and silently.
Perfect for urban use, the Stop &
Start system reduces fuel consump-
tion and exhaust emissions as well
as the noise level when stationary.
Operation
- with the 6-speed electronic
gearbox system, at speeds be-
low 4 mph (6 km/h), press the
brake pedal or put the selector
lever in position N .
Going into engine STOP mode
The "ECO" warning lamp
comes on in the instrument
panel and the engine goes
into standby: If your vehicle is fi tted
with the system, a time
counter calculates the
sum of the periods in
STOP mode during a journey. It rests
itself to zero every time the ignition
is switched on with the key.
For your comfort, during parking
maoeuvres, STOP mode is not avail-
able for a few seconds after coming
out of reverse gear.
STOP mode does not affect the func-
tionality of the vehicle, such as for ex-
ample, braking, power steering...
Never refuel with the engine
in STOP mode; you must
switch off the ignition with the key. Special cases: STOP mode
unavailable
In this case, the "ECO"
warning lamp fl ashes for a
few seconds then goes off.

This operation is perfectly normal.
STOP mode is not invoked when:
- the driver's door is open,
- the driver's seat belt is not fas-
tened,
- the vehicle has not exceeded 6 mph (10 km/h) since the last
engine start using the key,
- the electric parking brake is ap- plied or being applied,
- the engine is needed to maintain a comfortable temperature in the
passenger compartment,
- demisting is active,
- some special conditions (bat- tery charge, engine tempera-
ture, braking assistance, ambient
temperature...) where the engine
is needed to assure control of a
system.

In the event of a malfunction with
the system, the "ECO OFF" switch
warning lamp fl ashes then comes
on continuously.
Have it checked by a CITROËN
dealer.
In the event of a fault in STOP mode,
the vehicle may stall. It is then nec-
essary to switch off the ignition and
start the engine again using the
key.
Operating fault
The Stop & Start system
makes use of advanced
technology. Specialist knowledge
is needed for any work on the sys-
tem, which can only be assured by
CITROËN dealers. Before working under the
bonnet, deactivate the Stop &
Start system to avoid any risk
of injury resulting from automatic
operation of START mode.
Maintenance
This system requires a battery with
a special specifi cation and technol-
ogy (reference numbers available
from CITROËN dealers).
Fitting a battery not listed by
CITROËN introduces the risk of
malfunction of the system.
