At any time, press the "ECO OFF"
switch todeactivate the system.
This is confirmed by the switch warning lamp coming on accompanied by the display of amessage.


Deactivation

For safety reasons or to ensure smooth
operation, START mode is invoked
automatically when:
- you open the driver's door,
- you unfasten the driver's seat belt,
- the speed of the vehicle exceeds 15 mph (25 km/h) with a manual gearbox or 7 mph (11 k m/h) with the 6 -speed electronic
gearbox system,
- the electric parkin
g brake is being applied,
- some special conditions (battery charge,engine temperature, braking assistance,
ambient temperature...
) where the engine is
needed to assure control of a system.

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.

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.

219Driving
No aler t will be given in the following situations:
- in the presence of stationary objects (parked vehicles, barriers, street lamps,road signs...),
- with vehicles moving in the opposite
direction,
- drivin
g on a sinuous road or a sharp corner,
The alert is given by a warning lamp whichcomes on in the door mirror on the side inquestion as soon as a vehicle - car, lorry,cycle - is detected and the following conditions are fulfilled:


- all the vehicles must be moving in the same
direction,

- the speed of
your vehicle is between 7 and
75 mph (12 and 140 km/h),

- the difference in speed between your
vehicle and the other vehicles must be lessthan 6 mph (10 km/h),

- the traffic must be flowing normally,

- in the case of an over taking manoeuvre,
if this is prolonged and the vehicle beingover taken remains in the blind spot,

-
you are driving on a straight or slightly curved road,

- your vehicle is not pulling a trailer, a caravan...

- when overtakin
g (or being over taken by) a
very long vehicle (lorry, coach...) which is at the same time detected at the rear in theblind spot angle and present in the driver's
for ward field of vision,

- in ver
y heavy traffic: vehicles detected in
front and behind are confused with a lorryor a stationary object,

- when overtaking quickly.

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.

it requires a programmed speed of at least
20 mph (30 km/h). The speed limiter is switched off by manual foperation of the control. The programmed speed can be exceeded
temporarily by pressing the accelerator firmly
beyond the point of resistance.
To return to the programmed speed, simply release the accelerator pedal.
The programmed speed remains in the memorywhen the ignition is switched off.
