AT A GLANCE
Limit the causes of excess consumption
Spread loads throughout the vehicle; place the heaviest items in
the bottom of the boot, as close as possible to the rear seats.
Limit the loads carried in the vehicle and reduce wind resistance
(roof bars, roof rack, bicycle carrier, trailer...). Use a roof box in
preference.
Remove roof bars and roof racks after use.
At the end of winter, remove snow tyres and refit your summer
tyres.
Observe the recommendations on maintenance
Check the tyre pressures regularly, when cold, referring to the
label in the door aperture, driver's side.
Carry out this check in particular:
- before a long journey,
- at each change of season,
- after a long period out of use.
Don't forget the spare wheel and the tyres on any trailer or
caravan.
Have your vehicle serviced regularly (engine oil, oil filter, air
filter, cabin filter...) and observe the schedule of operations in the
maintenance and warranty guide.
When refuelling, do not continue after the 3
rd cut-off of the nozzle
to avoid any overflow.
At the wheel of your new vehicle, it is only after the fi rst 1 800 miles
(3 000 kilometres) that you will see the fuel consumption settle
down to a consistent average.

SERVICE INDICATOR
For a few seconds after the ignition is
switched on, the spanner symbolising the
service indicator comes on: the screen
informs you when the next service is due,
in accordance with the servicing schedule
indicated in the maintenance and warranty
guide. This information is determined in
relation to the distance travelled since the
previous service.
After a few seconds, the display returns to
its usual functions. A long press returns you to the main menu.
Refer to the "Technology on board -
Vehicle configuration" section.
Deterioration of the engine oil
Refer to the list of checks in the
maintenance and warranty guide
which was given to you on handover of
the vehicle.
Reminder of servicing information
At any time, to access the service indicator,
press briefly on the MODE button.
Use the up/down arrows to see
the scheduling and engine oil wear
information.
Pressing the MODE button again allows
you to return to the various display
menus.

Resetting to zero
The stopping of the permanent flashing of
the indicator is carried out by a qualified
workshop equipped with a diagnostic tool. This 2 nd warning lamp, coupled
with the 1 st , comes on in the
instrument panel when the oil
has not been changed and the
deterioration of the oil has reached another
threshold. To avoid the risk of damage, have
the oil changed without waiting for this level. The warning lamp flashing and,
if your vehicle has the function,
a message displayed at every
engine start: the system has
detected deterioration of the engine oil.
Have the oil changed as soon as possible.
For 3.0 litre HDi engines, the engine speed
is restricted to 3 000 rpm, then 1 500 rpm
until the oil change is done. Have the engine
oil changed to avoid any risk of damage.

Levels and checks
Used products
Avoid prolonged contact of used oil or fluids
with the skin.
Most of these fluids are harmful to health or
indeed very corrosive.
Do not discard used oil or fluids into sewers
or onto the ground.
Take used oil to a CITROËN dealer or
a qualified workshop (France) or to an
authorised waste disposal site.
LEVELS
These regular maintenance operations
will keep your vehicle in good running
order. Ask for advice at a CITROËN dealer
or consult the maintenance and warranty
guide contained in the handbook pack.
To maintain the reliability of engines and
emission control systems, the use of
additives in engine oil is prohibited.
Changing the brake fluid
The brake fluid must be changed at
the intervals stated, according to the
manufacturer's servicing schedule.
Use fluids recommended by the
manufacturer, which fulfil DOT4 standards.
The level must be between the MIN and
MAX marks on the reservoir.
If fluid has to be added frequently, this
indicates a failure which must be checked by
a CITROËN dealer or a qualified workshop
as soon as possible.
If you have to remove/refit the
engine styling cover, handle it
with care to avoid damaging the
fixing clips. Dipstick
There are two marks on
the dipstick:
Oil change
It is imperative that this is carried out at the
intervals specified in the manufacturer's
servicing schedule. Ask for advice at at
CITROËN dealer.
Remove the dipstick before filling.
Check the level after filling (never exceed
the maximum mark).
Screw the cap back onto the sump before
closing the bonnet.
Viscosity selection
When topping-up, the oil selected must meet
the manufacturer's requirements.
Warning lamps
Checking by means of the warning
lamps on the instrument panel is
described in the "Ready to go -
Instruments and controls" section.
A
= maximum
If you fill past this mark,
contact a CITROËN dealer
or a qualified workshop.
B = minimum
Never allow the level to fall
below this mark.
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.

Levels and checks

The presence of this label, in particular
with the Stop & Start system, indicates the
use of a specific 12 V lead-acid battery
with special technology and specification.
The involvement of a CITROËN dealer
or a qualified workshop is essential when
replacing or disconnecting the battery. These operations will keep your vehicle
in good running order. Ask for advice
from a CITROËN dealer or refer to the
maintenance and warranty guide included in
the handbook pack.
CHECKS
Battery
At the start of winter, have your battery
checked by a CITROËN dealer or a qualified
workshop.
Bleeding water from the Diesel filter
If this warning lamp comes on,
bleed the filter, or bleed regularly
each time the engine oil is
changed.
To drain the water out, unscrew the bleed
screw or the water in Diesel sensor, located
at the base of the filter. Leave open until
all of the water has been drained out. Then
tighten the bleed screw or the water sensor.
Air filter and passenger compartment filter
A clogged passenger compartment filter
may reduce the performance of the
air conditioning system and generate
undesirable odours. The replacement
intervals for these components are given in
the maintenance and warranty guide.
Depending on the environment (dusty
atmosphere...) and the use of the vehicle
(urban driving...), change them twice as
often if necessary.
Refer to the "Checks - Under the
bonnet" section.
HDi engines use advanced technology.
All work requires a special qualification
which is guaranteed by a CITROËN dealer
or a qualified workshop.

CHECKS
Levels and checks
Manual gearbox
Have the level checked in accordance with
the manufacturer's servicing schedule.
Good practice
To check the main levels and certain
components, in accordance with the
manufacturer's servicing schedule, refer to
the pages of the maintenance and warranty
guide which correspond to your vehicle's
engine.
Only use products recommended by
CITROËN or products of equivalent quality
and specification.
In order to optimise the operation of units as
important as the braking system, CITROËN
selects and offers specific products.
Oil filter
Change the filter regularly, in accordance
with the manufacturer's servicing schedule.
Brake pads
Brake pad wear depends on the style of
driving, in particular for vehicles which are
used in town, over short distances. It may
be necessary to check the thickness of the
pads, even between services.
Brake disc/drum wear status
For any information relating to checking
the brake disc/drum wear status, contact a
CITROËN dealer or a qualified workshop.
Parking brake
Where the parking brake travel is too great
or there is a reduction in the performance
of the system, the parking brake should be
adjusted, even between services.
Have the system checked by a CITROËN
dealer or a qualified workshop.
If this warning lamp comes on,
have the brake pad wear checked
by a CITROËN dealer or a
qualified workshop. In order to avoid damaging the
electrical units, high pressure washing
to clean the engine compartment is strictly
prohibited.
After washing the vehicle dampness, or in
winter, ice may form on the brake discs and
pads: braking efficiency may be reduced.
Make some light brake applications to dry
and de-ice the brakes.
