Operation
You have identifi ed a parking
space:

 Press button A to select the func-
tion.

 Activate the direction indicator
on the side where the space is to
be measured.

 During the measuring, go for-
ward the length of the space, at
a speed less than 12 mph (ap-
prox. 20 km/h), to prepare for
your manoeuvre.
The system then measures the size of the space.

 The system informs you of the
level of diffi culty of the manoeuvre
via a message on the multifunction
screen accompanied by a gong.

 Depending on the message is-
sued by the system, you may or
may not be able to perform the
manoeuvre.
Parking possible

Parking diffi cult

Parking not advised
The function displays the following
types of message: The function deselects itself auto-
matically:
- 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 there is a malfunction,
have the system checked
by a CITROËN dealer.
If the lateral distance between your
vehicle and the parking space is too
large, the system may not be able to
measure the space.
- The function remains available
after each measurement and
thus can measure more than
one space during your search.
- In bad weather conditions or in winter, make sure that the sen-
sors are not covered by dirt, or
by ice or snow.
- The parking space sensor func- tion deactivates the front park-
ing assistance during the space
measuring phase when you are
in forward gear.

LANE DEPARTURE WARNING SYSTEM
System which detects the involun-
tary crossing of longitudinal traffi c
lane markings on the ground (con-
tinuous or discontinuous line).
Sensors, fi tted below the front
bumper, trigger a warning if the vehi-
cle drifts (speed higher than 50 mph
(80 km/h)).
This system operates to its full poten-
tial above all when used on motor-
ways and main roads. Activation

 Press button A , the indicator light
comes on.
Deactivation

 Press button A again, the indica-
tor light switches 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 marking on the ground has been
crossed on the right,
- on the left-hand side, if the mark- ing 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 di-
rection marking (arrow) or non-stand-
ard marking (graffi ti) is crossed. Operating fault In the event of a malfunction, the service
warning light comes on, accompanied
by an audible signal and a message on
the multifunction display.
Consult a CITROËN dealer.
The lane departure warning system
cannot, in any circumstances, re-
place the need for vigilance and re-
sponsibility on the part of the driver. The detection may be disrupted:
- if the sensors are dirty (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.

CHECKING LEVELS
Check all of these levels regularly
and top them up if necessary, unless
otherwise indicated.
If a level drops signifi cantly, have the
corresponding circuit checked by a
CITROËN dealer.
Oil level
Draining the engine
Refer to the servicing booklet for
details of the interval for this opera-
tion. Oil specifi cation
The oil must correspond to your
engine and conform to the manufac-
turer's recommendations.
Brake fluid level
Draining the circuit
Refer to the servicing booklet for
details of the interval for this opera-
tion.
This fl uid must be changed regularly.
Fluid which has been used exces-
sively may cause a loss of braking
effi ciency.
Fluid specifi cation
The brake fl uid must conform to the
manufacturer's recommendations
and fulfi l the DOT4 standards.
Coolant level
Draining the circuit
The coolant does not have to be
changed.
Fluid specifi cation
The coolant must conform to the
manufacturer's recommendations.
The reading will only be
correct if the vehicle is on
level ground and the engine
has been off for more than
15 minutes.
The check is carried out either when
the ignition is switched on using the
oil level indicator on the instrument
panel, or using the dipstick.
Between two oil changes, the con-
sumption should not exceed 0.5 litre
per 600 miles (approx. 1 000 km).
Check this level also between each
scheduled service and before long
journeys. The brake fl uid level should
be close to the "MAX" mark.
If it is not, check the brake
pad wear.
The coolant level should be
close to the "MAX" mark but
should never exceed it.
When the engine is warm, the tem-
perature of the coolant is regulated
by the fan. This can operate with the
ignition off.

On vehicles which are fi tted with
a particle emission fi lter, the fan
may operate 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 pressure to drop. When
the pressure has dropped, remove
the cap and top up the level.
In order to maintain the
reliability of the engine and
emission control system,
the use of additives in the engine
oil is prohibited.
