Service indicator
The display, located in the control
block, informs you when the next
service will be due in accordance
with the "Manufacturer's" servicing
schedule indicated in the servicing
booklet. This information is determined
in relation to the distance travelled
since the previous service. A few seconds after the ignition is
switched on, the oil level is displayed,
then the total distance recorder
resumes normal operation showing the
total and trip distances.
The distance remaining before the next
service is less than 500 miles/1 000 km
Each time the ignition is switched on
and for a few seconds, the spanner
fl ashes and the number of miles/
kilometres remaining is displayed: A few seconds after the ignition is
switched on, the oil level is displayed,
then the total distance recorder
resumes normal operation and the
spanner remains lit. This indicates that
a service should be carried out shortly.

The service is overdue
Each time the ignition is switched on
and for a few seconds, the spanner
fl ashes and the excess distance is
displayed.
With the engine running the
spanner remains lit until the
service has been carried out.

Example: 4 800 miles/km remain
before the next service is due. When
the ignition is switched on and for a
few seconds, the display shows:
Refer to the list of checks in the
servicing booklet which was given
to you on delivery of the vehicle.
Operation
A few moments after the ignition
has been switched on, the spanner
indicating a service operation lights
up; the display for the total distance
recorder tells you (in round fi gures)
the distance remaining before the next
service.
The points at which a service is due
are calculated from the last indicator
zero reset.
The point at which a service is due is
determined by the distance travelled. For further information, consult

TRACTION CONTROL (ASR)
AND DYNAMIC STABILITY
CONTROL (ESP)
Activation of the ASR and ESP
systems
When the ignition is on, the ASR and
ESP systems are always active. Disarming the ASR/ESP systems
In certain conditions (vehicle stuck in
mud or snow, or on loose ground...), it
could prove useful to disarm the ASR
and ESP systems to make the wheels
spin and regain grip.
- Press the switch, situated under the
steering wheel on the right of the
fascia.
The indicator light comes on
accompanied by a message:
the ESP and ASR systems
no longer act on the engine
operation, but continue to act
on the brakes. Operating check
The ASR/ESP systems offer
increased safety during normal
driving, but should not incite the
driver to take risks or to drive at high
speed.
The operation of these systems is
ensured if the recommendations
of the manufacturer regarding
the wheels (tyres and rims), the
braking components, the electronic
components and the fi tting and repair
procedures within the CITROËN
network are observed.
After an impact, have the system
checked by a CITROËN dealer.

They engage again:

automatically above 30 mph (50 km/h),

- manually by pressing the switch again.
Operation of the ASR and
ESP systems
The warning light fl ashes if
the ASR or ESP is activated.
These systems are linked and
complement the ABS.
The ASR system optimises drive to
prevent the wheels skidding, by acting
on the brakes of the drive wheels
and on the engine. It also allows the
directional stability of the vehicle to be
improved on acceleration.
If there is a variation between the
trajectory followed by the vehicle and
that required by the driver, the ESP
system automatically acts on the
engine and the brake of one or more
wheels, in order to put the vehicle back
on course, within the limits of the laws
of physics.
When a malfunction of the
systems occurs, the indicator
light comes on, accompanied
by an audible signal and a
message on the display.
Contact a CITROËN dealer to have the
system checked.

Towing a trailer
On the contrary, use a high gear to
lower the engine speed and reduce
your speed.
In all cases, pay attention to the
coolant temperature.
Brakes: towing increases the braking
distance. Drive at a moderate speed,
change down early and brake
gradually. Please contact a CITROËN dealer fi rst
for further information .
Automatic adjustment
For vehicles with Xenon bulbs, and if
the change in load makes it necessary,
this system automatically corrects the
height of the beam after approximately
2 minutes. The driver is then assured
of having optimum lighting and not
causing a nuisance to other road
users.
In certain cases of particularly
arduous use (towing the
maximum load up a steep slope
in high temperatures), the engine
automatically limits its power. In this
case, cutting off the air conditioning
allows the engine power to be
recovered, and therefore the towing
speed to be signifi cantly increased
(approximately 12 mph [20 km/h]
more). Sequential control of the
gearbox may also become unavailable.
Lighting
Bicycle carrier
Refer to the "Identifi cation
features" section of chapter 8. Refer to the "Steering wheel
controls" section of chapter 3.
When using a trailer connection,
you must add a fuse. Refer to
the "Changing a fuse" section of
chapter 7.

If the coolant temperature warning light
comes on, stop the vehicle and switch
off the engine as soon as possible.

Tyres: check the tyre pressures of
the towing vehicle and of the trailer,
observing the recommended pressure.
Side wind: sensitivity to side wind is
increased. Drive smoothly and at a
moderate speed.
Towbar
We recommend the use of original
CITROËN towbars, which have been
tested for endurance from the design
stage of your vehicle.
Towing equipment must be fi tted in
accordance with the manufacturer’s
instructions, with particular attention to
the towing capacities of your vehicle,
the load towed, the nose weight and
the electrical connection. As this fi tting
should be carried out by a professional,
we recommend that you entrust the
fi tting of this equipment to a CITROËN
dealer.
In accordance with the general
instructions referred to above, we draw
your attention to the risk connected
with fi tting a towbar or other electrical
accessory which is not recommended
by the CITROËN network. Fitting such
equipment could result in a failure of
your vehicle’s electronic system. Manual adjustment
Adjust your headlamps so as not to
dazzle other road users. Check the
electrical signalling of the trailer.
If you fi t a bicycle carrier on
the tailgate, deactivate the
rear wiper from the display's
confi guration menu.

FUEL CIRCUIT DISARMED
In a serious collision, a mechanism
automatically prevents fuel from
reaching the engine. The fl ashing of this warning
light is accompanied by a
message on the display.
DIESEL REPRIMING
PUMP
If you should run out of fuel, it is
necessary to re-prime the circuit:
- fi ll the fuel tank with at least fi ve litres of diesel,
- squeeze and release the manual re-priming pump, under the bonnet
under the protective cover, until fuel
appears in the transparent pipe,
- operate the starter until the engine starts.
Check that there is no odour or
leakage of fuel outside the vehicle and
re-establish the fuel supply:
- switch off the ignition
(STOP position).
- remove the key.
- put the key back in the ignition.
- switch on the ignition and start.
Quality of the fuel used for Diesel
engines
The Diesel engines are perfectly
compatible with biofuels which conform
to current and future European
standards (diesel fuel which complies
with standard EN 590 mixed with a
biofuel which complies with standard
EN 14214) available at the pumps
(containing up to 7 % Fatty Acid
Methyl Ester).
The B30 biofuel can be used in certain
Diesel engines; however, this use
is subject to strict application of the
special servicing conditions. Consult a
CITROËN dealer.
The use of any other type of (bio)fuel
(vegetable or animal oils, pure or
diluted, domestic fuel...) is strictly
prohibited (risk of damage to the
engine and fuel circuit).

These regular maintenance
operations will keep your vehicle
in good running order. Consult the
instructions at CITROËN dealerships
or in the servicing booklet enclosed in
the handbook pack. To maintain the reliability of engines
and emission control systems, the use
of additives in engine oil is prohibited.
Oil change
It is imperative that this is carried out at
the intervals specifi ed and the viscosity
grade of the oil selected must fulfi l the
requirements in accordance with the
manufacturer's servicing schedule.
Consult the instructions at CITROËN
dealerships.
Remove the dipstick before fi lling.
Check the level after fi lling (never
exceed the max mark).
Screw the cap back onto the sump
before closing the bonnet.
LEVELS
If you have to remove/refi t the
engine style cover, handle it with
care to avoid damaging the fi xing
clips.
Dipstick
Warning lights
Oil level
Check the level regularly and top up
between changes. The maximum
consumption is 0.5 litre per 600 miles
(1 000 km).
Check the level with the vehicle level,
engine cold, using the dipstick.
Viscosity selection
In all cases, the oil selected must meet
the manufacturer's requirements. Checking by means of the
warning lights on the instrument
panel is described in chapter 2,
"Instruments and controls" section.
Changing the brake fluid
The brake fl uid must be changed at
the intervals stated, according to the
manufacturer's servicing schedule.
Use fl uids recommended by the
manufacturer, which fulfi l DOT4
standards.
The level must be between the MIN
and MAX marks on the reservoir.
If fl uid has to be added frequently,
this indicates a failure which must be
checked by a CITROËN dealer as
soon as possible.
There are two marks
on the dipstick:

A = maximum
If you fi ll past this
mark, contact a
CITROËN dealer.

B = minimum
Never allow the level
to fall below this
mark.

Levels
Cooling system
Only use the fl uid recommended by
the manufacturer.
Otherwise, you risk seriously damaging
your engine.
When the engine is warm, the
temperature of the coolant is controlled
by the engine fan. As this fan can
operate with the ignition key removed
and because the cooling system is
pressurised, wait for at least one hour
after the engine has stopped before
carrying out any work.
Slacken the cap by 1/4 of a turn to
release the pressure to prevent any
risk of scalding. When the pressure
has dropped, remove the cap and top
up the level with coolant.
If fl uid has to be added frequently,
this indicates a failure which must be
checked by a CITROËN dealer as
soon as possible.
Power steering fluid level
The vehicle must be parked on level
ground with the engine cold. Unscrew
the cap integrated with the gauge and
check the level which must be between
the MIN and MAX marks. During regeneration of the particle
emission fi lter, relay noise may be
heard under the fascia.
If the message is still displayed and
the service warning light remains on,
contact a CITROËN dealer.
Diesel additive level (Diesel with
particle emission filter)
When this occurs with the engine running,
this is due to the start of saturation of
the particle emission fi lter (exceptionally
prolonged urban driving conditions: low
speed, long traffi c jams, ...).
In order to regenerate the fi lter, you
are advised to drive at a speed of
more than 40 mph (60 km/h) as soon
as possible, when traffi c conditions
permit, for at least fi ve minutes (until
the message disappears and the
service warning light is switched off).
Topping up
The level must be between the MIN
and MAX marks on the expansion
bottle. If more than 1 litre of fl uid is
required to top up the level, have the
system checked by a CITROËN dealer.
Windscreen wash and headlamp
wash level
For best quality cleaning and for your
safety, we would advise that you use
products of the CITROËN range.
To avoid ice forming, do not use water.
Topping up
It is imperative that this additive is
topped up by a CITROËN dealer
without delay.
Used oil
Avoid prolonged contact of used oil
with the skin.
Brake fl uid is harmful to health and
very corrosive.
Do not dispose of used oil, brake
fl uid or coolant into drains or onto
the ground but into the containers
dedicated to this use at CITROËN
dealerships.
The minimum level of this
additive is indicated by
lighting of the service warning
light, accompanied by an
audible signal and a message
on the display.
