The trajectory control systems
offer increased safety in normal
driving, but this should not en-
courage the driver to take extra
risks or drive at high speed.
The correct functioning of these
systems is assured provided
that manufacturer's recommen-
dations are observed on:
- wheels (tyres and rims),
- braking components,
- electronic components,
- assembly and repair proce-
dures.
After an impact, have these sys-
tems checked by a CITROËN
dealer or a qualifi ed workshop.
Reactivation
These systems are reactivated automati-
cally each time the ignition is switched
back on or from 30 mph (50 km/h).
)
Press the "ESP OFF"
button again
to reactivate them manually.
If this warning lamp comes on,
accompanied by an audible
signal and a message in the
screen, this indicates a fault
with these systems.

SEAT BELTS
Front seat belts
The front seat belts are fi tted with a pre-
tensioning and force limiting system.
This system improves safety in the front
seats in the event of a front or side im-
pact. Depending on the severity of the
impact, the pretensioning system in-
stantly tightens the seat belts against
the body of the occupants.
The pretensioning seat belts are active
when the ignition is on.
The force limiter reduces the pressure
of the seat belt on the chest of the oc-
cupant, so improving their protection.
Fastening
)

in the buckle.
)
Check that the seat belt is fastened
correctly by pulling the strap.

Lateral airbags
System which protects the driver and
front passenger in the event of a seri-
ous side impact in order to limit the risk
of injury to the chest, between the hip
and the shoulder.
Each lateral airbag is fi tted in the seat
backrest frame, door side.
Deployment
The lateral airbags are deployed uni-
laterally in the event of a serious side
impact applied to all or part 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 lateral airbag infl ates between the
hip and shoulder of the front occupant
of the vehicle and the corresponding
door trim panel.

Impact detection zones
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 curtain airbag is built into the pil-
lars and the upper passenger compart-
ment area.
Deployment
The curtain airbag is deployed at the
same time as the corresponding lateral
airbag in the event of a serious side
impact applied to all or part 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 curtain airbag infl ates between the
front or rear occupant of the vehicle and
the windows.
Operating fault
If this warning lamp comes on
in the instrument panel, accom-
panied by an audible signal and
a message in the screen, con-
tact a CITROËN dealer or a qualifi ed
workshop to have the system checked.
The airbags may no longer be deployed
in the event of a serious impact.
In the event of a minor impact or
bump on the side of the vehicle
or if the vehicle rolls over, the air-
bag may not be deployed.
In the event of a rear or front
collision, the airbag is not de-
ployed.

GEAR EFFICIENCY INDICATOR *
System which reduces fuel consump-
tion by advising the driver to change up
on vehicles fi tted with a manual gearbox.
*
According to engine.
Operation
The system intervenes only when driv-
ing 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 recommenda-
tions must not be considered compulso-
ry. In fact, the confi guration of the road,
the amount of traffi c 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.
- You press the accelerator pedal
moderately.
Example:
- You are in third gear.
- The system may suggest that you
engage a higher gear, if appropriate.
The information appears in the instru-
ment 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
(fi rm pressure on the accelerator
pedal, for example, when over-
taking...), the system will not rec-
ommend a gear change.
The system never suggests:
- engaging fi rst gear,
- engaging reverse gear,
- engaging a lower gear.

AUTOMATIC GEARBOX
Six speed automatic gearbox which of-
fers a choice between the comfort of
fully automatic operation, enhanced by
sport and snow programmes, or manu-
al gear changing.
Four driving modes are offered:
- automatic
operation for electronic
management of the gears by the
gearbox,
- sport
programme for a more dy-
namic style of driving,
- snow
programme to improve driv-
ing when traction is poor,
- manual
operation for sequential
changing of the gears by the driver.

LANE DEPARTURE WARNING
SYSTEM
The lane departure warning sys-
tem cannot, in any circumstances,
replace the need for vigilance and
responsibility on the part of the
driver.
Activation
)
Press this button, the indicator lamp
comes on.
Deactivation
)
Press this button again, the indicator
lamp goes off.
The status of the system remains in the
memory when the ignition is switched
off.
Detection
You are warned by the vibration of the
driver's seat cushion:
- on the right-hand side, if the mark-
ing 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 di-
rection indicator is switched off.
A warning may be transmitted if a direc-
tion marking (e.g. arrow) or non-standard
marking (e.g. graffi ti) is crossed.
Operating fault
The detection may be impeded:
- if the sensors are dirty (mud,
snow...),
- if the markings on the ground
are worn,
- if there is little contrast be-
tween the markings on the
ground and the road surface.
System which detects the involuntary
crossing of longitudinal traffi c lane mark-
ings on the ground (solid or broken
line).
Sensors, fi tted 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 particularly useful on
motorways and main roads. In the event of a malfunction,
the service warning lamp
comes on, accompanied by
an audible signal and a message in the
screen.
Contact a CITROËN dealer or a qualifi ed
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
fi eld of vision), as soon as this presents
a potential danger.
Operation
)
On switching on the ignition, or en-
gine running, press this button to
activate the function; the warning
lamp comes on.
This system is designed to im-
prove 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 traffi c, to
asses the distances and relative
speeds of other vehicles and
to predict their movements be-
fore deciding whether to change
lane.
The blind spot sensor system
can never replace the vigilance
and responsibility of the driver.
Sensors fi tted in the front and rear bum-
pers 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 overtaking a vehicle slowly.
