Release
With the ignition on or the engine run-
ning, to release the parking brake,
press on the brake pedal, pull then
release control A .
The full application of the parking
brake is confi rmed by: - the extinction of the warning lamp on control

A and of warning lamp P
on the instrument panel,
- the display of a message "parking brake released" on the multifunc-
tion screen.
If you pull control A without pressing
the brake pedal, the parking brake
will not be released and the "Foot on
brake" warning lamp will light up on
the instrument panel.
When stationary, with the
engine running, do not
press the accelerator pedal
unnecessarily, as you may
release the parking brake. Maximum application
If necessary, you can utilise
maxi-
mum application of the parking
brake. It is obtained by means of
a long pull on control A , until you
see the message "parking brake ap-
plied" and a beep is heard.
Maximum application is essential:
- in the case of a vehicle towing a caravan or a trailer, if the au-
tomatic functions are activated
but you are applying the parking
brake manually,
- when the gradient you are parked on is variable in its effect (e.g. on
a ferry, in a lorry, during towing),
- in the case of towing, a loaded vehicle or parking on a gradient,
turn the front wheels towards the
pavement and engage a gear
when you park,
- after a maximum application, the release time will be longer. Particular situations
In certain situations (e.g. starting
the engine), the parking brake can
automatically alter its force. This is
normal operation.
To advance your vehicle a few cen-
timetres without starting the engine,
but with the ignition on, press on the
brake pedal and release the park-
ing brake
by pulling then releasing
control A .
The full release of the parking brake
is confi rmed by the extinction of
warning lamp P (red) on the instru-
ment panel and the display of a
message "parking brake released"
on the multifunction screen.
If the parking brake malfunctions

while applied or if the battery runs
fl at, an emergency release is always
possible.

Emergency unlocking In the event of the electronic parking
brake malfunctioning or the battery
running fl at, an emergency man-
ual device can unlock the parking
brake.

 Immobilise the vehicle, with the
engine running, by engaging fi rst
gear (manual gearbox), position

P (automatic gearbox) or M or

R (6-speed electronic gearbox),
then switch off the engine.
If it is impossible to immobilise the vehicle, do not action the
control and urgently contact a
CITROËN dealer.

 Fetch the vehicle blocks and the
unlocking device (braided cable)
from the toolbox.

 Immobilise the vehicle by placing
blocks at the front and at the rear
of one of the rear wheels.

 Slide the front left-hand seat
back as far as possible.

 Lift up the fl oor plug B in the
carpet under the seat.
 Pierce the tab C on the tube D
with the unlocking device.

 Place the unlocking device in the
tube D .

 Turn the unlocking device clock-
wise . For safety reasons, it is

essential to continue turning the
device as far as it will go or until
you hear a knocking noise. The
parking brake is released.

 Remove the unlocking device
and store it with the blocks in the
toolbox.
- The operation of the parking brake reinitialises when the
ignition is switched off then on
again. If the reinitialisation of the
parking brake proves impossible,
contact a CITROËN dealer.
- The subsequent time required for application may be longer
than during normal operation.
For safety reasons, after this manoeuvre it is essential to cont act a CITROËN dealer urgently to have the plug
replaced.
Following an emergency unlocking, immobilisation o f the vehicle is no longer guaranteed once the manual emergency
unlocking has been deployed and the manual control does not allow the re-application of your parking brake.
Take no action, either on control A , or stopping starting the engine while the unlocking de vice is engaged.
Take care not to allow moisture or dust in the proximity of th e plug.

Operation
You have identifi ed a parking space:


Press button A to select the function.

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

 During the measuring, go
forward the length of the space,
at a speed less than 12 mph
(approx. 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 sensors
are not covered by dirt, or by ice or
snow.
- The parking space sensor function deactivates the front
parking 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
potential above all when used on
motorways 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 direction marking (arrow) or
non-standard marking (graffi ti) is
crossed. Operating fault
In the event of a malfunction, the
service warning light comes on, ac-
companied by an audible signal and a
message on the multifunction display.
Consult a CITROËN dealer.
The lane departure warning system
cannot, in any circumstances,
replace the need for vigilance and
responsibility 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 de-
tails of the interval for this operation. Oil specifi cation
The oil must correspond to your en-
gine and conform to the manufactur-
er's recommendations.
Brake fluid level
Draining the circuit
Refer to the servicing booklet for de-
tails of the interval for this operation.
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 temperature of the coolant is
regulated by the fan. This can oper-
ate 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 en-
gine 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 re-
liability of the engine and
emission control system,
the use of additives in the engine
oil is prohibited.
