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.

SPEED LIMITER

System which prevents the vehicle
from exceeding the speed programmed
by the driver.
When the programmed speed limit is
reached, pressing the accelerator ped-
al no longer has any effect.
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 part of
the driver. The functions of this system are grouped
together on the steering mounted con-
trols.

Operation

The speed limiter is switched on
man-
ually: 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 ex-
ceeded temporarily by pressing the
accelerator fi rmly beyond the point of
resistance.
To return to the programmed speed,
simply release the accelerator pedal.
The programmed speed remains in the

(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)).
You can then change the programmed speed using but-
tons 2
and 3
:


- by + or - 1 mph (km/h) = short 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 to the corresponding paragraph.


)
Switch the speed limiter on by pressing button 4
.

)
Switch the speed limiter off by pressing button 4
: the
display confi rms that it has been switched off (Pause).


Exceeding the programmed speed

Pressing the accelerator pedal to exceed the programmed
speed will not have any effect unless you press the pedal
fi rmly
past the point of resistance
.
The speed limiter is deactivated temporarily and the pro-
grammed speed, which is still displayed, fl ashes.
Returning to the programmed speed, by means of intention-
al or unintentional deceleration of the vehicle, automatically
cancels the fl ashing of the programmed speed.


Exiting the speed limiter mode



)
Turn dial 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
fl ashing of the dashes.
Have it checked by a CITROËN dealer
or a qualifi ed workshop.
On a steep descent or in the
event of sharp acceleration, the
speed limiter will not be able to
prevent the vehicle from exceed-
ing the programmed speed.
To avoid any risk of jamming of
the pedals:


- ensure that the mat is posi-
tioned correctly,

- do not fi t one mat on top of
another.

)
Switch the speed limiter back on by pressing button 4

again.

The cruise control system can-
not, in any circumstances, re-
place the need to respect speed
limits, nor can it replace the need
for vigilance and responsibility
on the part of the driver.
You are advised to keep your
feet near the pedals at all times.






CRUISE CONTROL

System which automatically maintains
the speed of the vehicle at the value
programmed by the driver, without any

When the cruise control is
switched on, be careful if you
maintain the pressure on one of
the programmed speed chang-
ing buttons: this may result in a
very rapid change in the speed
of your vehicle.
Do not use the cruise control on
slippery roads or in heavy traffi c.
On a steep descent, the cruise
control will not 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 avoid any risk of jamming of
the pedals:


- ensure that the mat is posi-
tioned correctly,

- never fi t 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 fi eld of detection
of sensors located in the bumper.
Certain types of obstacle (stake, road-
works 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 cir-
cumstances, 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 frequen-
cy of which increases as the vehicle ap-
proaches the obstacle.
The sound emitted by the speaker (right
or left) indicates the side on which the
obstacle is located.
When the distance between the vehicle
and the obstacle becomes less than
approximately thirty centimetres, the
audible signal becomes continuous.


Visual assistance
This supplements the audible signal
by displaying bars in the multifunction
screen which move progressively near-
er to the vehicle. When the obstacle is
near, the "Danger" symbol is also dis-
played in the screen.

CHECKS
184

























CHECKING LEVELS

Check all of these levels regularly and
top them up if necessary, unless other-
wise indicated.
If a level drops signifi cantly, have the
corresponding system checked by a
CITROËN dealer or a qualifi ed work-
shop.

When working under the bonnet,
take care, as certain areas of the
engine may be extremely hot (risk
of burns).
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 level
indicator in the instrument panel, or using
the dipstick.
It is normal to top up the oil level between
two services. CITROËN recommends that
you check the oil level, and top up if neces-
sary, every 3 000 miles (5 000 kilometres).

Oil level


Engine oil change
Refer to the servicing booklet for the
interval for this operation.
In order to maintain the reliability 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 engine
and conform to the manufacturer's rec-
ommendations.



Brake fluid level

The brake fl uid level should be
close to the "MAX" mark. If it is
not, check the brake pad wear.

Changing the fl uid
Refer to the servicing booklet for the
interval for this operation.

Fluid specifi cation
The brake fl uid must conform to the
manufacturer's recommendations and
meet the DOT4 standard.



Power steering fluid level

The power steering fl uid level
should be close to the "MAX"
mark. Unscrew the cap, with
the engine cold, to check the
level.


Coolant level

The coolant level should be
close to the "MAX" mark but
should never exceed it.
When the engine is warm, the
temperature of the coolant is regulated
by the fan. This can operate with the ig-
nition off.

On vehicles which are fi tted with a par-
ticle emission fi lter, the fan may oper-
ate after the vehicle has been switched
off, even if the engine is cold.
In addition, as the cooling system is
pressurised, wait at least one hour after
switching off the engine before carrying
out any work.
To avoid any risk of scalding, unscrew
the cap by two turns to allow the pres-
sure to drop. When the pressure has
dropped, remove the cap and top up
the level.

Changing the coolant
The coolant does not have to be
changed.

Coolant specifi cation
The coolant must conform to the manu-
facturer's recommendations.

CHANGING A FUSE

Access to the tools

The extraction tweezer is attached to
the back of the dashboard fusebox
cover.
For access to it:


)
unclip the cover by pulling at the
top right, then left

)
disengage the cover completely
and turn it over,

)
remove the carrier, on the back of
which the tweezer is fi tted.



Changing a fuse

Before changing a fuse:


)
the cause of the failure must be
identifi ed and rectifi ed,

)
all electrical consumers must be
switched off,

)
the vehicle must be immobilised
with the ignition off,

)
identify the failed fuse using the ta-
bles and diagrams in the following
pages.
Good

Failed

To replace a fuse, you must:


)
use the special tweezer to extract
the fuse from its housing and check
the condition of its fi lament.

)
always replace the failed fuse with
a fuse of the same rating (same co-
lour); the use of a fuse of different
rating fuse may cause malfunctions
(risk of fi re).
If the fault recurrs soon after replacing the
fuse, have the electrical system checked
by a CITROËN dealer or a qualifi ed work-
shop.
Installing electrical
accessories
Your vehicle's electrical system
is designed to operate with stan-
dard or optional equipment.
Before installing other electrical
equipment or accessories on
your vehicle, contact a CITROËN
dealer or a qualifi ed workshop.
CITROËN will not accept respon-
sibility for the cost incurred in
repairing your vehicle or for recti-
fying malfunctions resulting from
the installation of accessories not
supplied and not recommended
by CITROËN and not installed in
accordance with its instructions,
in particular when the combined
consumption of all of the addition-
al equipment connected exceeds
10 milliamperes.
The replacement of a fuse not
mentioned in the tables below
may cause a serious malfunc-
tion of your vehicle. Contact a
CITROËN dealer or a qualifi ed
workshop.
