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:
-
b
efore a long journey,
-

a
t each change of season,
-

a
fter 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...) and
observe the schedule of operations recommended by the manufacturer.
When refuelling, do not continue after the third cut-off of the nozzle to
avoid any over flow.
At the wheel of your new vehicle, it is only after the first 1 800 miles
(3
000 kilometres) that you will see the fuel consumption settle down to
a consistent average.

Quality of the fuel used for
petrol engines
The petrol engines are per fectly compatible
with E10 type petrol biofuels (containing 10 %
ethanol), conforming to European standards
EN 228 and EN 15376.
E85 type fuels (containing up to 85 % ethanol)
are reserved exclusively for vehicles marketed
for the use of this type of fuel (BioFlex
vehicles). The quality of the ethanol must
comply with European standard EN 15293.
For Brazil only, special vehicles are marketed
to run on fuels containing up to 100 % ethanol
(E100 type).
Quality of the fuel used for
Diesel engines
The Diesel engines are per fectly 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.
Contact a CITROËN dealer or a qualified
workshop.
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 system).
1.6 litre petrol engines, even though they have
been designed to operate on 95 RON petrol,
can accept 90 RON petrol without engine
adjustments, but with a slight deterioration in
performance.
2.0 litre petrol engines can accept 90 RON or
higher petrol.

Checks

213
Checking levels
Take care when working under the bonnet, as certain areas of the engine may be extremely hot (risk of burns) and the cooling fan could start at
any time (even with the ignition off).
Oil level
The check of the the level is done
out with the dipstick, located under
the bonnet. Refer to the description
of your engine compartment for the
position of the dipstick.Engine oil change
Refer to the maintenance and warranty guide
for details of the interval for this operation.
In order to maintain the reliability of the engine
and emission control system, never use
additives in the engine oil.
Oil specification
The oil must be the correct grade for your
engine and conform to the manufacturer's
recommendations.
Check all of these levels regularly, in line with the maintenance and warranty guide. Top them up if necessary, unless other wise indicated.
If a level drops significantly, have the corresponding system checked by a CITROËN dealer or a qualified workshop.
Dipstick
There are two marks on the dipstick:
A = maximum
If the level is above this
mark, contact a CITROËN
dealer or a qualified
workshop.
B = minimum
Top up the level through the
oil filler orifice, using the
correct grade of oil for your
engine. The level must never
be below this mark.
This check will only be correct if the vehicle is
on level ground and the engine has been off for
more than 30 minutes.
It is normal to top up the oil level between
two services (or oil changes). CITROËN
recommends that you check the level, and top
up if necessary, every 3 000 miles (5 000 km).
After topping up the oil, the check when
switching on the ignition with the oil level
indicator in the instrument panel is not valid
during the 30 minutes after topping up.

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.

12 V battery
Electrolyte level
For access to the battery, refer to the
"12V battery" section.Refer to the maintenance and
warranty guide for details of the
replacement intervals for these
components.
Air filter and passenger compartment filter
Replace the oil filter each time the
engine oil is changed.
Refer to the maintenance and
warranty guide for details of the
replacement interval for this
component.
Oil filter
If necessary, top up using distilled water,
removing the battery cap from each cell.
Check the electrolyte level at least once
a
month.
When carrying out work on the battery, refer
to "12V battery" section for details of the
precautions to be taken before disconnecting
the battery and following its reconnection.
Unless other wise indicated, check these components in accordance with the maintenance and warranty guide and according to your engine.
Other wise, have them checked by a CITROËN dealer or a qualified workshop.
The electrolyte level must be between the
"LOWER LEVEL" and "UPPER LEVEL" marks.
Depending on the environment (e.g. dusty
atmosphere) and the use of the vehicle
(e.g. city driving), replace them twice as often
if necessary .
A clogged passenger compartment filter may
have an adverse effect on the per formance
of the air conditioning system and generate
undesirable odours.
