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.

The system may suffer tem-
porary 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 alerts
(for example, the presence of a
fog of water droplets in the blind
spot angle is interpreted as a ve-
hicle).
In bad or wintry weather, ensure
that the sensors are not covered
by mud, ice or snow.
Take care not to cover the warn-
ing 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.
Operating fault
In the event of a fault, the warning lamp
in the button fl ashes then goes off.
Have it checked by a CITROËN dealer
or a qualifi ed workshop.
The system is automatically de-
activated when towing with a
towbar approved by CITROËN.

The function displays the following types
of message:
Parking possible
Parking diffi cult
Parking not advised
The function deselects itself automati-
cally:
- when you engage reverse gear,
- when you switch off the ignition,
- if measuring is not requested,
- within fi ve minutes of selection of
the function,
- if the vehicle speed exceeds the
threshold of 45 mph (approx. 70 km/h)
for one minute.
If the lateral distance between your ve-
hicle and the parking space is too large,
the system may not be able to measure
the space.
If there is a fault, have the sys-
tem checked by a CITROËN
dealer or a qualifi ed workshop.
The system remains available after
each measurement and can therefore
measure several spaces in succession.
In poor or wintry weather, ensure that
the sensors are free of dirt, ice or
snow.
The parking space sensor system de-
activates the front parking sensors
when measuring forwards.

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.
