The lateral airbags are deployed unilaterally in
the event of a serious side impact applied to all
or par t of the side impact zone B
, perpendicular
to the longitudinal centreline of the vehicle on a

Safety






Curtain airbags

System which protects the driver and
passengers (with the exception of the rear
centre passenger) in the event of a serious side
impact in order to limit the risk of injury to the
side of the head.
Each cur tain airbag is built into the pillars and
the upper passenger compar tment area.

Deployment

The cur tain airbag is deployed at the same
time as the corresponding lateral airbag in the
event of a serious side impact applied to all or
par t of the side impact zone B
, perpendicular
to the longitudinal centreline of the vehicle on a
horizontal plane and directed from the outside
towards the inside of the vehicle.
The cur tain airbag inflates between the front or
rear occupant of the vehicle and the windows.


Operating fault

In the event of a minor impact or bump
on the side of the vehicle or if the
vehicle rolls over, the airbag may not be
deployed.
In the event of a rear or front collision,
the airbag is not deployed.
If this warning lamp comes on in the
instrument panel, accompanied by
an audible signal and a message in
the screen, contact a CITROËN dealer or a
qualified workshop to have the system checked.
The airbags may no longer be deployed in the
event of a serious impact.

Gear shift indicator *
System which reduces fuel consumption by advising the driver to change up on vehicles fitted with a manual gearbox.


Operation

The system inter venes only when driving
economically.
Depending on the driving situation and your
vehicle's equipment, the system may advise
you to skip one or more gears. You can
follow this instruction without engaging the
intermediate gears.
The gear engagement recommendations must
not be considered compulsory. In fact, the
configuration of the road, the amount of traffic
and safety remain determining factors when
choosing 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 system may suggest that you engage a
higher gear, if appropriate.
The information appears in the instrument
panel in the form of an arrow accompanied by
the suggested gear.

In the case of driving which makes
particular demands on the performance
of the engine (firm pressure on the
accelerator pedal, for example, when
over taking...), the system will not
recommend 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 pedal
moderately.

Six speed automatic gearbox which offers a
choice between the comfor t of fully automatic
operation, enhanced by spor t and snow
programmes, or manual gear changing.
Four driving modes are offered:


- automatic
operation for electronic
management of the gears by the gearbox,

- sport
programme for a more dynamic style
of driving,

- snow
programme to improve driving when
traction is poor,

- manual
operation for sequential changing
of the gears by the driver.

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.

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.

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.
