the control lever A,
- displa
y of the message"Handbrake on".
When the driver
’s door is opened with the engine running, a message is displayed
accompanied by an audible signal if the parkingbrake has not been applied, except in the case
of an automatic gearbox with the gear lever in position P.P

the P warning lamp in the controllever Agoing off,

- displa
y of the message
"Handbrake off".

If you pull control lever Awithout pressingAthe brake pedal, the parking brake will not be released and a warning lamp willcome on in the instrument panel.


Maximum application

If necessary, you can make a maximum application
of the parking brake. This is obtained by means of a long pullon the control
l
ever A, until you see the message "Handbrake on maximum" and a beep is heard.
Maximum application is essential:

- in the case of a vehicle towing a caravan
or a trailer, if the automatic functions are
activated but you are applying the parkingbrake manually,

- when the gradient you are parked on may
vary (e.g. on a ferry, on a lorry, duringtowing).

In the case of towing, a loaded vehicle or parking on a gradient, make amaximum application of the parkingbrake then turn the front wheelstowards the pavement and engage agear when you park.
After a maximum application, the release time will be longer.

With the vehicle stationary, the parking brake is automatically applied when the engine is
switched off.
Automatic application,
engine off
In the case of towing, a loaded vehicleor parking on a gradient, turn the front wheels towards the pavement and engage a gear when you park.
Before leaving the vehicle, ensurethat parking brake warning lamp inthe instrument panel is on fixed (notflashing). Never leave a child alone inside the vehicle with the ignition on, as they could release the parking brake.

Particular situations
In cer tain situations (e.g. star ting the engine),
the parking brake can automatically alter its force. This is normal operation.
To advance
your vehicle a few centimetres without star ting the engine, but with the ignition
on, press on the brake pedal and release the
parking brake by pulling
then releasing
the control lever A. The full release of the parkingbrake is confirmed by the warning lampsin the control lever A
and in the instrumentpanel going off and display of the message"Handbrake off".
If the parking brake develops a fault while appliedor if the battery runs flat, an
emergency release is always possible.



Emergency braking



In the event of failure of the electronicstability control system, signalled
by the illumination of this warning
lamp, braking stability is then not guaranteed.
In this event, stability must be assured by thedriver by repeating alternate "pull-release" actions on the control lever A.

In the event of a failure of the main servicebrake or in an exceptional situation (e.g. driver
taken ill, under instruction, etc) a continuous
pull on the control lever Awill stop the vehicle.
The electronic stability control provides stability
durin
g emergency braking.
If the emergency braking malfunctions,
the message "Parking brake faulty" will be
displayed.

In the event of the electric parking brakemalfunctioning or the battery running flat, anemergency manual device can release theparking brake.)Immobilise the vehicle (or keep it
stationary, if the brake pedal is pressed),
with the engine running, by engagingfirst gear (manual gearbox), position P(automatic gearbox) or position M or R(6 -speed electronic gearbox system).
Emergency release
)
Switch off the engine but leave the ignition on. If it is not possible to immobilise the
vehicle, do not operate the control andcontact a CITROËN dealer or a qualified
workshop without delay.) Fetch the two vehicle blocks B
and the
release device C, located under the boot carpet.
)Immobilise the vehicle by placing the blocks
in front or behind the two front wheels,
opposite to the direction of the slope.)Remove the storage box under the bootcarpet for access to the emergency releasedevice.

with the blocks in the toolbox under theboot carpet.


For safety reasons, after this operationit is essential to contact a CITROËN dealer or a qualified workshop without delay to replace the protective cover.
Following an emergency unlocking,immobilisation of the vehicle is nolonger assured once the manual emergency release has been deployed
and the manual control does not allowthe re-application of your parkingbrake.
Take no action, either on the control lever A, or stopping starting the engine while the release device is engaged.
Take care not to allow moisture or dust in the proximity of the protective cover. - The operation o

Operation
The system intervenes only when driving economically.
Depending on the driving situation and your
vehicle's equipment, the s
ystem may advise you to skip one or more gears. You can
follow this instruction without engaging the
intermediate gears.
The gear engagement recommendations mustnot be considered compulsory. In fact, the configuration of the road, the amount of trafficand safety remain determining factors whenchoosing 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.

- The s
ystem may suggest that you engage a
higher gear, if appropriate.
The in
formation appears in the instrument panel in the form of an arrow accompanied bythe suggested gear.


In the case of driving which makespar ticular demands on the performance of the engine (firm pressure on theaccelerator pedal, for example, whenover taking...), the system will notrecommend a gear change. The system never suggests:


- engaging first gear,

- engaging reverse gear,

- engaging a lower gear.

According to engine.
Example:


- You are in third gear.

-
You press the accelerator pedalmoderately.

Te m p o r a ry control of gear changing
You can temporarily take over control of gear changing using the "+"
and "-"steeringmounted paddles: if the engine speed allows,
the request to change gear is acted on.
This function allows you to anticipate cer tain
situations such as overtaking a vehicle or theapproach to a corner.
After a few moments without any action on
the control paddles, the gearbox resumesautomatic control of the gears.

Manual mode
)Select position A .



Automated mode
AUTOand the gear engaged
appear in the instrument panel
screen.
The gearbox operates in auto-active mode,
without an
y action on the par t of the driver. Itcontinuously selects the most suitable gear for:


- optimisation of fuel consumption,

- the st
yle of driving,

- the profile of the road.

- t
he vehicle load.
)
Select position M .
The gears engaged appear in succession in theinstrument panel screen.
The
gear change requests areonly acted on if the engine speedpermits.
It is not necessary to release the accelerator during gear changes.
When braking or slowing down, the gearbox changes down automatically to allow the
vehicle to accelerate in the correct gear.
On sharp acceleration, the gearbox will not change up unless the driver acts on the gear
lever or the steering mounted paddles.
Never select neutral N
when driving.


Never select neutral N
while the vehicleis moving.



You can change mode at any time by moving the gear lever from A
