Maintenance indicator zero reset Engine oil level indicator
After each service, the maintenance
indicator must be reset to zero.
The procedure for resetting to zero
is as follows:

 switch off the ignition,

 press and hold the trip distance
recorder zero reset button,

 switch on the ignition; the dis-
tance recorder display begins a
countdown,

 when the display indicates "=0" ,
release the button; the spanner
disappears. System which informs the driver
whether the engine oil level is correct
or not.
This information is displayed for a
few seconds when the ignition is
switched on, after the service infor-
mation.
The level read will only be correct if
the vehicle is on level ground and
the engine has been off for more
than 15 minutes.
Oil level correct
Oil level low
This is indicated by the fl ashing of

"OIL" , accompanied by an audible
signal and a message on the multi-
function screen.
If the low oil level is confi rmed by a
check using the dipstick, it is essen-
tial that the level is topped up to pre-
vent damage to the engine. Oil level gauge fault
This is indicated by the fl ashing of

"OIL --" . Contact a CITROËN dealer.
Dipstick
Refer to the "Checks" section to lo-
cate the dipstick and the oil fi ller cap
on your engine. There are 2 marks on
the dipstick:
- A = max; never ex-
ceed this level,
- B = min; top up the
level via the oil fi ller
cap, using the type
of oil suited to your
engine.
Following this operation, if you wish
to disconnect the battery, lock the
vehicle and wait at least fi ve minutes
for the zero reset to be taken into ac-
count.

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 an anti-tamper function.
Exterior perimiter 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 com-
partment.
The alarm is triggered if anyone breaks
a window or moves inside the vehicle.
If you wish to leave a pet in the ve-
hicle or a window partially open,
deactivate the interior volumetric
protection.
Anti-tamper 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 us-
ing the locking button on the re-
mote control.
The alarm is activated; the indicator
light on button A fl ashes once per
second.
Deactivation

 Unlock the vehicle using the
unlocking button on the remote
control.
The alarm is deactivated; the indica-
tor light on button A switches off. Locking the vehicle with
exterior protection alarm only
Deactivation of the interior
volumetric protection

 Switch off the ignition.

 Within ten seconds, press but-
ton A until the indicator lamp is lit
continuously.

 Get out of the vehicle.

 Lock or deadlock the vehicle us-
ing the locking button on the re-
mote control.
The exterior protection alarm alone
remains activated; the indicator
lamp on button A fl ashes once per
second.
To be effective, this deactivation
must be carried out each time the
ignition is switched off.
Reactivation of the interior
volumetric protection

 Unlock the vehicle using the
unlocking button on the remote
control.

 Relock the vehicle using the re-
mote control.
The alarm is activated again with
both types of protection; the indica-
tor lamp on button A switches off.

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
bumper, trigger a warning if the vehi-
cle 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 indica-
tor 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,
accompanied 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.
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 en-
gine and conform to the manufactur-
er'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
Draining the system
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 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.
