multifunction screen, this indicates that the
parkin
g brake is still on or has not been
properly released.

Stopping the vehicle
Operating fault

With the ignition on, the flashing of AUTO
,
accompanied by an audible signal and amessage in the screen, indicates a malfunction
of the gearbox.
Have it checked by a CITROËN dealer or a qualified workshop.
When immobilising the vehicle, withthe engine running, you must place thegear lever in neutral N
. Before carrying out any work in the engine compar tment, ensure that thegear lever is in neutral N
and that the parking brake is applied. Whatever the circumstances, you mustmanually apply the parking brake whenparking, unless the parking brake is programmed in automatic mode. Be
fore switching off the engine, you can:


- move to position N
to engage neutral,
or

- leave the
gear engaged; in this case, it will
not be possible to move the vehicle.
To engage reverse gear R, the vehicle must be
immobilised with your foot on the brake pedal. )Select position R.

At low high speed, if reverse gear is requested,
the N indicator flashes and the gearbox goes
into neutral automatically. To engage reverse, put the gear lever in position N , then position R.
In both cases, you must apply the parkingbraketo immobilise the vehicle.
Reverse

Engagement of reverse gear is accompanied by an audible signal.

Invalid value during manualoperation
This symbol is displayed if a gear
is not engaged correctly (selector
between two positions).

Stopping the vehicle
Before switching off the engine, you canengage position Por N
to place the gearbox in neutral.
In both cases, apply the parking brake toimmobilise the vehicle, unless it is programmedto automatic mode.

If the lever is not in position P, when thePdriver's door is opened or approximately45 seconds after the ignition is switched off, there is an audible signal and amessage appears.)Return the lever to position P
; the audible signal stops and themessage disappears.


Operating fault

When the ignition is on, the lighting of this
warning lamp, accompanied by an audible
signal and a message in the multifunction
screen, indicates a gearbox malfunction.
In this case, the gearbox switches to back-up
mode and is locked in 3rd
gear. You may feel
a substantial knock when changing from Pto R
and from N
to R
. This will not cause any
damage to the gearbox.
Do not exceed 60 mph (10 0 km/h), local speed restrictions permitting.
Have it checked by a CITROËN dealer or aqualified workshop.
This warning lamp may also come on if a door
is opened.
You risk damaging the gearbox:


- if you press the accelerator and brake pedals at the same time,

- if you force the lever from position Pto another position when the batteryis flat.

To reduce fuel consumption when stationary for long periods with the engine running (traffic jam...), positionthe gear lever at Nand apply theparking brake, unless it is programmed in automatic mode.

Stop & Start The Stop & Start system puts the engine temporarily into standby - STOP mode - during stops in the traffic (red lights, traffic jams, or other...). The engine restar ts automatically - START mode - as soon as you want to move off. The restar t takes place instantly, quickly and silently.
Per
fect for urban use, the Stop & Star t system reduces fuel consumption and exhaust emissions as well as the noise level when stationary.
Operation
Going into engine STOP mode
With the electronic gearbox system, for your comfor t during parking maoeuvres, STOP mode is not available for a few seconds after coming out of reverse gear.STOP mode does not affect the functionality of the vehicle, such asbraking, power steering, for example.
Never refuel with the engine in STOPmode; you must switch off the ignition with the key. Th
e "ECO"warning lamp comes on
in the instrument panel and the engine goes into standby automatically:
-with a manual gearbox , at speeds below
12 mph (20 km/h), when you put the gear lever into neutral and release the clutchpedal,
- with the 6-speed electronic gearbox
system, at a speed below 5 mph (8 km/h),
when you press the brake pedal or put thegear lever into position N.
If your vehicle is fitted with the system, a time counter calculates
the sum o
f the periods in STOP
mode during a journey. It resets
itself to zero every time the ignition
is switched on with the key.
STOP mode is not invoked when:


- the driver's door is open,

- the driver's seat belt is not
fastened,

- the vehicle has not exceeded 6 mph (10 km/h)since the last engine star t using the key,

- the electric parking brake is applied or
bein
g applied,

- the engine is needed to maintain acomfortable temperature in the passenger compartment,

- demisting is active,

- some special conditions (battery charge, engine temperature, braking assistance,ambient temperature...) where the engine isneeded to assure control of a system.


Special cases: STOP modeunavailable

In this case, the "ECO"warning lamp
flashes for a few seconds, then goes off.
This operation is per fectly normal.

The system is reactivated automaticallyat every new star t using the key.
Reactivation

This system requires a specific battery with aspecial specification and technology (reference numbers available from a CITROËN dealer or a qualified workshop).
Fitting a battery not listed by CITROËN
introduces the risk of malfunction of the system. In the event of a malfunction with the s
ystem,
the "ECO OFF"switch warning lamp flashes,
then comes on continuously.
Have it checked by a CITROËN dealer or aqualified workshop.


Operating fault
Maintenance

Before doing anything under the bonnet, deactivate the Stop & Start system to avoid any risk of injury resulting from automatic operation of STA R T mode.

The Stop & Star t system makes use of advanced technology. All work on this type of battery must be done only by a CITROËN dealer or a qualifiedworkshop. Pr
ess the "ECO OFF"switch again.
The system is active again; this is confirmed
by the switch warning lamp going off and the
display of a message.
In the event of a fault in STOP mode, thevehicle may stall. All of the instrumentpanel warning lamps come on.Depending on version, an alert message may also be displayed askingyou to put the gear lever into position Nand put your foot on the brake pedal.
It is then necessary to switch off the ignition, then restart the engine using the key.

Lane departure warning system

System which detects the involuntary crossing
of longitudinal traffic lane markings on the ground (solid or broken line).
Sensors, fitted below the front bumper, trigger a
warning if the vehicle drifts over a lane marking (speed higher than 50 mph (80 km/h)).
This system is par ticularly useful on motor waysand main roads.
Activation
)Press this button, the indicator lamp comes on.


The lane depar ture warning systemcannot, in any circumstances, replacethe need for vigilance and responsibility on the par t of the driver.
Deactivation
You are warned by the vibration of the driver's seat cushion:
- on the right-hand side, if the marking on theground has been crossed on the right,
- on the left-hand side, if the marking on the ground has been crossed on the left.
No warning is transmitted while the direction indicator is active and for approximately 20 seconds after the direction indicator is
switched off.
A warning may be transmitted if a direction
marking (e.g. arrow) or non-standard marking(e.g. graffiti) is crossed.
Detection
Operatin
g fault


The detection may be impeded:


- if the sensors are dir ty (mud, snow...),

- if the markings on the ground are worn,

- if there is little contrast between themarkings on the ground and the road surface.
)
Press this button again, the indicator lampgoes off.
The status of the system remains in the
memory when the ignition is switched off. In the event of a malfunction,
the ser vice warnin
g lamp comes
on, accompanied by an audible signal and a message in the screen.
Contact a CITROËN dealer or a qualified
workshop.

Blind spot sensors
of the presence of another vehicle in the blind spot angle of their vehicle (areas masked from
the driver's field of vision), as soon as thispresents a potential danger.

Operation


This system is designed to improve safety when driving and is in no circumstances a substitute for the use of the interior rear view mirror and door mirrors. It is the driver'sresponsibility to constantly check the traffic, to asses the distances and relative speeds of other vehicles and to predict their movements before deciding whether to change lane.
The blind spot sensor system can never replace the vigilance and responsibility of thedriver.

)On switching on the ignition, or enginerunning, press this button to activate the function; the warning lamp comes on.
Sensors fitted in the front and rear bumpers
monitor the blind spots. A warnin
g lamp appears in the door mirror on
the side in question:


- immediatel
y, when being overtaken,

- after a delay of about one second, whenover taking a vehicle slowly.

Operating fault

In the event of a fault, the warning lamp in thebutton flashes then goes off.
Have it checked by a CITROËN dealer or aqualified workshop.


The system may suffer temporary interference in certain weather conditions(rain, hail...).
In par ticular, driving on a wet surface or moving from a dry area to a wet area can cause false alerts (for example, the presence of a fog of water droplets in the blind spot angle is interpreted as avehicle).
In bad or wintry weather, ensure thatthe sensors are not covered by mud, ice or snow. Take care not to cover the warning zone in the door mirrors or the detection zones on the front and rear bumpers with adhesive labels or other objects; they may hamper the correct operation of the system.

)To deactivate the system, press this button again; the warning lamp goes off.
The state of the system remains in memory on switching off the ignition.
The system is automatically deactivated when towing with a towbar approved by CITROËN.

System which prevents the vehicle fromexceeding the speed programmed by the driver.
When the programmed speed limit is reached, pressing the accelerator pedal no longer has any effect.





Speed limiter
