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.

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

The speed limiter cannot, in any circumstances, replace the need to respect speed limits, nor can it replace the need for vigilance and responsibility on the par t of the driver.

speed limiter mode is selected but is not
switched on
(Pause).You do not have to switch the speed limiter on
in order to set the speed. )Set the speed value by pressing button 2or 3 (e.g.: 55 mph (90 km/h)).


Programming
You can then change the programmed speed using buttons 2
and 3:


- by + or - 1 mph (km/h) = shor t press,

- in steps of + or - 5 mph (km/h) = maintained press.
If speed memorisation is available and activated on your vehicle, theprogrammed speed will stop at the closest memorised speed; refer to thecorresponding paragraph.)Switch the speed limiter on by pressing button 4 . )Switch the speed limiter off by pressing button 4
: the display confirms that it has been switched off (Pause).)Switch the speed limiter back on by pressing button 4
again.



Exceeding the programmed speed

Pressing the accelerator pedal to exceed the programmed speed will not have
any effect unless you press the pedal firmlypast the ypoint of resistance .
The speed limiter is deactivated temporarily and the programmed speed,
which is still displayed, flashes.
Returning to the programmed speed, by means of intentional or unintentional
deceleration of the vehicle, automatically cancels the flashing of the programmed speed.
On a steep descent or in the event of sharp acceleration, the speed limiter will not be able to prevent the vehicle from exceeding the programmedspeed.
To avoid any risk of jamming of the pedals:


- ensure that the mat is positioned correctly,

- do not fit one mat on top of another.



Exiting the speed limiter mode
)
Turn dial 1to the "0"
position: the speed
limiter mode is deselected. It disappears
from the screen.


Operating fault

In the event of a fault with the speed limiter,
the speed is cleared resulting in flashing of the dashes.
Have it checked by a CITROËN dealer or a qualified workshop.

Cruise control

Driving

Programming
)Turn dial 1to the "CRUISE"
position: thecruise control mode is selected but is not switched on (Pause).)Set the programmed speed by accelerating
to the required speed, then press button 2
or 3(e.g.: 70 mph (11 0 k m / h)); the cruise control system is activated (ON).
You can then chan
ge the programmed speed using buttons 2
and 3
:


- by + or - 1 mph (km/h) = shor t press,

- in steps of + or - 5 mph (km/h) = maintained press.
If storing speeds is available and activated on your vehicle, the programmed speed will stop at the closest stored speed; refer to thecorresponding section. )Stop the cruise control system by pressing button 4
: this is confirmed in the screen (Pause).
)Switch on the cruise control again with another press on button 4 .




Exceeding the programmed speed

Intentional or unintentional exceeding of the programmed speed results in
flashing of this speed in the screen.
Return to the programmed speed, by means of intentional or unintentional
deceleration of the vehicle, automatically cancels the flashing of the speed.


Exiting cruise control mode
)Turn dial 1to the "0"
position: the cruise control mode is deselected.
It disappears from the screen.



Operating fault

In the event of a cruise control malfunction,
the speed is cleared resulting in flashing of the dashes.
Have it checked by a CITROËN dealer or a
qualified workshop.

When the cruise control is switched on,be careful if you maintain the pressure on one of the programmed speed changing buttons: this may result in a very rapid change in the speed of your vehicle. Do not use the cruise control on slipperyroads or in heavy traffic. On a steep descent, the cruise control willnot be able to prevent the vehicle from exceeding the programmed speed. On steep climbs or when towing, the programmed speed may not be reached or maintained.
To a v o i d a ny risk of jamming of the pedals:


- ensure that the mat is positioned correctly,

- never fit one mat on top of another.

Parking sensors
This system indicates the proximity of an
obstacle (person, vehicle, tree, gate, etc.) which comes within the field of detection of sensorslocated in the bumper.
Cer tain types of obstacle (stake, roadworks cone, etc.) detected initially will no longer be detected at the end of the manoeuvre due to
the presence of blind spots.


This function cannot, in any circumstances, take the place of the vigilance and responsibility of the driver.
The system is switched on by engaging reverse
gear. This is accompanied by an audible signal.
The system is switched off when you exit reverse gear.


Rear parking sensors


Audible assistance

The proximity information is given by an
intermittent audible signal, the frequency of which
increases as the vehicle approaches the obstacle.
The sound emitted b
y the speaker (right or left)
in
dicates the side on which the obstacle is located.
When the distance between the vehicle and
the obstacle becomes less than approximatelythirty centimetres, the audible signal becomes continuous.



Visual assistance

This supplements the audible signal bydisplaying bars in the multifunction screen
which move progressively nearer to the vehicle.
When the obstacle is near, the "Danger"symbol is also displayed in the screen.

Checks

























Checking levels
Check all of these levels regularly and top them up if necessary, unless other wise indicated.
If a level drops si
gnificantly, have the corresponding system checked by a CITROËN dealer or a qualified workshop.


Oil level
Engine oil change
Refer to the servicing booklet for the inter val for
this operation.
In order to maintain the reliabilit
y of the engine and emission control system, the use of additives in the engine oil is prohibited.
Oil specifi cation
The oil must correspond to your engineand conform to the manufacturer'srecommendations.



Brake fluid level


Changing the fl uid

Refer to the servicing booklet for the inter val for
this operation.

Fluid specifi cation

The brake fluid must conform to themanufacturer's recommendations and meet theDOT4 standard.
Th
e brake fluid level should be closeto the "MA X" mark. If it is not, check
the brake pad wear.
The reading will only be correct if the
vehicle is on level ground and the engine
has been off for more than 30 minutes. The check is carried out either when
the ignition is switched on using the oil levelindicator in the instrument panel, or using the dipstick.
When working under the bonnet, take care, as cer tain areas of the engine may be extremely hot (risk of burns).
It is normal to top up the oil level
between two services. CITROËN recommends that you check the oillevel, and top up if necessary, every 3 000 miles (5 000 kilometres).
