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 ways
and main roads.

Activation



)
Press this button, the indicator lamp comes
on.

The lane depar ture warning system
cannot, in any circumstances, replace
the 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 the
ground 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
Operating 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 the
markings on the ground and the
road surface.



)
Press this button again, the indicator lamp
goes 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 warning 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


This driving assistance system warns the driver
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 this
presents 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's
responsibility 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 the
driver.



)
On switching on the ignition, or engine
running, 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 warning lamp appears in the door mirror on
the side in question:


- immediately, when being overtaken,

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

217Driving

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,

- driving on a sinuous road or a sharp corner, The aler t is given by a warning lamp which
comes on in the door mirror on the side in
question 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 less
than 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 being
over taken remains in the blind spot,

- you are driving on a straight or slightly
cur ved road,

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

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

- in very heavy traffic: vehicles detected in
front and behind are confused with a lorry
or a stationary object,

- when overtaking quickly.

Operating fault

In the event of a fault, the warning lamp in the
button flashes then goes off.
Have it checked by a CITROËN dealer or a
qualified workshop.
The system may suffer temporary
interference in certain weather
conditions(rain, hail...).
In particular, driving on a wet sur face
or moving from a dry area to a wet area
can cause false aler ts (for example, the
presence of a fog of water droplets in
the blind spot angle is interpreted as a
vehicle).
In bad or wintry weather, ensure that
the 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.

A reminder of the speed and the state of the
system (on/off) is displayed in the instrument
panel.

System which prevents the vehicle from
exceeding 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. The functions of this system are grouped
together on the steering mounted controls.

2.
Programmed value decrease button.

3.
Programmed value increase button.

(see "Memorising speeds")



Steering mounted controls

The programmed information is grouped
together in the instrument panel screen.

(see "Memorising speeds")


Displays in the instrument panel


Operation

The speed limiter is switched on
manually:
it requires a programmed speed of at least
20 mph (30 km/h).
The speed limiter is switched off
by manual
operation 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 memory
when the ignition is switched off.

221Driving


)
Tu r n d i a l 1
to the "LIMIT"
position: the
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 2
or 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, the
programmed speed will stop at the closest memorised speed; refer the
the corresponding 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 firmly
past the point 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 programmed speed.
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



)
Tu r n d i a l 1
to 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

System which automatically maintains the
speed of the vehicle at the value programmed
by the driver, without any action on the
accelerator pedal.
The functions of this system are grouped
together on the steering mounted controls.

Operation

The cruise control is switched on
manually: it
requires a minimum vehicle speed of 25 mph
(40 km/h) and engagement of:


- four th gear on the manual gearbox,

- second gear on the electronic gearbox
system or automatic gearbox, in sequential
driving mode,

- position A
on the electronic gearbox
system or D
on an automatic gearbox.
The cruise control is switched off
