ALARM
System which protects and provides
a deterrent against the theft of your
vehicle. It provides two types of pro-
tection, exterior and interior, as well
as a self-protection function.
Exterior perimeter protection
The system detects opening of the
vehicle.
The alarm is triggered if anyone tries
to enter the vehicle by forcing a door,
the boot or the bonnet.
Interior volumetric protection
The system detects any variation in the
volume in the passenger compartment.
The alarm is triggered if anyone breaks
a window or moves inside the vehicle.
If you wish to leave a pet in the vehicle
or a window partially open, deactivate
the interior volumetric protection.
Self-protection function
The system detects the putting out
of service of its components.
The alarm is triggered if anyone tries
to put the wires of the siren, the central
control or the battery out of service.
Do not make any modifi cations to
the alarm system, this could cause
malfunctions. Locking the vehicle with full
alarm
Activation

 Switch off the ignition and get out
of the vehicle.

 Lock or deadlock the vehicle using
the locking button on the remote
control.
The alarm is activated; the indicator
lamp on button A fl ashes once per
second.
The exterior perimeter protection is
activated, 5 seconds after the loc-
king button on the remote control is
pressed. Deactivation

 Unlock the vehicle using the
unlocking button on the remote
control.
The alarm is deactivated; the indica-
tor lamp on button A switches off.

activated, 45 seconds after the loc-
king button on the remote control is
pressed.
If an opening - door or boot - is not
closed fully, the vehicle is not locked,
but the exterior perimeter protection
will be activated after 45 seconds at
the same time as the interior volu-
metric protection.

LANE DEPARTURE WARNING SYSTEM
System which detects the involun-
tary crossing of longitudinal traffi c
lane markings on the ground (solid
or broken line).
Sensors, fi tted below the front bum-
per, 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. Activation

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

 Press button A again, the indicator
lamp 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 (e.g. arrow) or
non-standard marking (e.g. graffi ti)
is crossed. Operating fault
In the event of a malfunction, the
service warning lamp comes on, ac-
companied by an audible signal and a
message on the multifunction screen.
Consult a CITROËN dealer.
The lane departure warning sys-
tem cannot, in any circumstances,
replace the need for vigilance and
responsibility on the part of the
driver. 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 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 system checked by a
CITROËN dealer.
Take care when working under the
bonnet, as some parts of the engine
can be extremely hot (risk of burns).
Oil level
Oil change
Refer to the Maintenance and
Warranty Guide for details of the in-
terval for this operation. Oil specifi cation
The oil must correspond to your engine
and conform to the manufacturer's
recommendations.
Brake fluid level
Fluid change
Refer to the Maintenance and
Warranty Guide for details of the in-
terval for this operation.
This fl uid must be changed regu-
larly. Fluid which has been used for
too long 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
Coolant change
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.
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 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, un-
screw the cap by two turns to al-
low 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.
