Service indicator zero reset Engine oil level indicator
After each service, the service indi-
cator 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 cor-
rect 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 en-
gine.
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.

Lost keys
Visit a CITROËN dealer with the vehi-
cle's V5 registration document and your
personal identifi cation documents.
The CITROËN dealer will be able to
retrieve the key code and the transpon-
der code required to order a replace-
ment key.
Remote control
The high frequency remote control is
a sensitive system; do not operate it
while it is in your pocket as there is a
possibility that it may unlock the ve-
hicle, without you being aware of it.
Do not repeatedly press the buttons
of your remote control out of range
and out of sight of your vehicle. You
run the risk of stopping it from wor-
king and the remote control would
have to be reinitialised.
The remote control does not operate
when the key is in the ignition, even
when the ignition is switched off, ex-
cept for reinitialisation.
Locking the vehicle
Driving with the doors locked may
make access to the passenger com-
partment by the emergency services
more diffi cult in an emergency.
As a safety precaution (with children
on board), remove the key from the
ignition when you leave the vehicle,
even for a short time. Anti-theft protection
Do not make any modifi cations to
the electronic engine immobiliser
system; this could cause malfunc-
tions.
When purchasing a second-
hand vehicle
Have the key codes memorised by a
CITROËN dealer, to ensure that the
keys in your possession are the only
ones which can start the vehicle.
Do not throw the remote
control batteries away, they
contain metals which are
harmful to the environment.
Take them to an approved collection
point.

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.
The interior volumetric protection is
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.

TYRE UNDER-INFLATION DETECTION
Sensors fi tted in each valve check
the tyre pressure during driving and
trigger a warning in the event of
malfunction (speed above 12 mph
(20 km/h)).
Under-infl ated tyre The tyre under-infl ation detection
system is an aid to driving which
does not replace the vigilance or
responsibility of the driver. Puncture
The service warning lamp
comes on in the instru-
ment panel, accompanied
by an audible signal and
a message on the multi-
function screen locating
the wheel concerned.
Check the tyre pressures as soon as
possible. This check must be carried
out when the tyres are cold. The
STOP warning lamp
comes on in the instru-
ment panel, accompanied
by an audible signal and
a message on the multi-
function screen locating
the wheel concerned.
Stop immediately, avoiding any sud-
den movement of the steering wheel
and the brakes.
Change the damaged wheel (punctured
or very defl ated tyre), and have the tyre
pressure checked as soon as possible.
Sensor(s) not detected or faulty
The service warning lamp
comes on in the instrument
panel, accompanied by an
audible signal and a mes-
sage on the multifunction
screen locating the wheel
or wheels which are not detected or
indicating a fault in the system.
Have the faulty sensor(s) checked by
a CITROËN dealer. All repairs and changing of tyres
on a wheel fi tted with this system
must be carried out by a CITROËN
dealer.
If, when changing a tyre, you in-
stall a wheel which is not detected
by your vehicle (example: fi tting
of snow tyres), you must have the
system reinitialised by a CITROËN
dealer.
This system does not avoid the
need to have the tyre pressures
checked regularly (refer to the
"Technical data - § Identifi cation
markings" section) to ensure that
the optimum dynamic perform-
ance of the vehicle is maintained
and prevent premature wear of the
tyres, particularly in arduous driv-
ing conditions (heavy load, high
speed).
The tyre pressures must be
checked cold, at least once a
month. Remember to check the
pressure of the spare wheel.
The tyre under-infl ation detection
system may experience temporary
interference due to electro-mag-
netic signals on a frequency close
to that used by the system.
This message is also displayed
when one of the wheels is away
from the vehicle (being repaired) or
when one or more wheels without a
sensor are fi tted.
The spare wheel is not fi tted with a
sensor.

Displays on the instrument panel
- The selector position is displayed in the instrument panel, on the left
on multifunction screens A and C
and on the right on the NaviDrive
multifunction screen.
- A back-lit position grille associ- ated with the selector shows the
position selected. Moving off

When the ignition is on, lighting of
the service warning lamp, accom-
panied by an audible signal and
the message "Gearbox faulty" in-
dicates a malfunction.
Consult a CITROËN dealer.
For safety:

 Position N can only be disen-
gaged if you are pressing the
brake pedal.

 If the gearbox is in position N
but the selector position is diffe-
rent, reposition the selector on N
in order to be able to start.
 To start the engine, the selector
must be in position N .

 Press fi rmly on the brake pedal.

 Operate the starter.

 When the engine is running,
place the selector on R , A or M
as desired.

 Check, in the instrument panel,
the position engaged.

 Release the brake pedal and
accelerate.
If the selector is not in position N ,
and/or if the brake pedal is not
pressed, the corresponding warning
lamp(s) are displayed and a mes-
sage informs you that at least one of
these two conditions is not met.
In this case, the engine will not start,
recommence the above procedure.
Engaging reverse gear
To engage reverse gear, move the
selector to R .

Only attempt to select reverse gear
when the vehicle is stationary.
If the vehicle is moving rapidly, if an in-
advertent attempt to engage reverse
gear is made, the warning lamp N will
fl ash and your vehicle will go auto-
matically into neutral. To re-engage a
gear, you have only to reposition the
selector on A , M or R .

Override of the programmed
speed
The accelerator pedal is equipped
with an end-of-travel switch. If you
action this switch by pressing the
pedal hard down, you can exceed
the memorised maximum speed at
any time.
During the time the speed is be-
ing exceeded, the displayed speed
fl ashes.
You have only to release the ac-
celerator pedal to return below the
maximum speed and render the
function active again.
If during the operation of the speed
limiter, the system is unable to keep
within the maximum speed (for exam-
ple on a steep descent or under heavy
acceleration) then the speed fl ashes.
Adapt your speed as necessary.
The function will re-engage when
your speed returns below the de-
sired maximum speed. Return to normal driving

 By moving the control 1 from po-
sition "LIM" to position 0 .

 By the engine stopping.
The speed previously chosen is still
memorised.
Operating fault
If there is a speed limiter malfunc-
tion, a message will display accom-
panied by an audible signal and
lighting of the service warning lamp.
Have it checked by a CITROËN
dealer.
On a steep downhill gradient or on
sharp acceleration, the speed limiter
will not be able to prevent the vehi-
cle from exceeding the programmed
speed.
Use of fl oor mats that are not ap-
proved by CITROËN may hinder
access to the accelerator pedal and
thus interfere with the functioning of
the speed limiter.
To avoid any risk of interfering with
the pedals:
- check that the fl oor mat is cor- rectly positioned,
- never use more than one fl oor mat.

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.

Screenwash and headlamp
wash fluid
Fluid specifi cation
For optimum cleaning and to avoid
freezing, this fl uid must not be topped
up or replaced with plain water.
Reservoir capacities:
- screenwash: approximately 3 litres,
- screenwash and headlamp wash: approximately 6 litres. Diesel additive level (Diesel
engine with particle emission
filter)
A low additive level is indicated by
lighting of the service warning lamp,
accompanied by an audible warning
and a message on the multifunction
screen.
Topping up
This additive must be topped up by
a CITROËN dealer without delay.
Used products
Avoid prolonged contact of
used oil or fl uids with the
skin.
Most of these fl uids are harmful to
health or indeed very corrosive.
Do not discard used oil or
fl uids into sewers or onto
the ground.
Take used oil to a CITROËN deal-
er (France) or an authorised waste
disposal site.
In the case of vehicles fi tted
with headlamp washers, the
minimum level of this fl uid is
indicated by an audible signal
and a message on the multifunction
screen.
Top up the level when you next stop
the vehicle.
