When the symbol begins to flash
rapidly (approximately twice per
second), there is not much fuel
remaining in your tank (approximately
5
litres).
You must fill the tank to avoid running
out of fuel.
Fuel tank
Capacity of the tank: approximately 60 litres.
Low fuel level
Filling
A label, affixed on the inside of the flap,
reminds you of the type of fuel to be used
according to your engine.
More than 5 litres of fuel must be added in
order to be registered by the fuel gauge.
Location of the cap
When the low fuel level is reached,
this indication appears in the
instrument panel screen. When it first
comes on, you have approximately
10 litres of fuel remaining.
The symbol flashes slowly (approximately
once per second).

This vacuum, which is completely normal, is
caused by the sealing of the fuel system.

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 (
di
esel 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 CITR
oËn

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.

primed if you run out of fuel; refer to the

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.

Coolant level
The coolant level should be between
the two marks.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, unscrew the cap
by two turns to allow the pressure to drop.
When the pressure has dropped, remove the
cap and top up the level.
Fluid specification
The coolant must conform to the
manufacturer's recommendations.
The brake fluid level should be close
to the "MA X" mark. If it is not, check
the brake pad wear.
Brake fluid level
Changing the fluid
Refer to the maintenance and warranty guide
for details of the interval for this operation.
Fluid specification
The brake fluid must conform to the
manufacturer's recommendations and meet
the
DOT3 or DOT4 standard.
The cooling fan may star t after switching
off the engine: take care with ar ticles and
clothing that might become caught by the
fan blades. When the engine is warm, the temperature of
the coolant is regulated by the fan.

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.

Particle filter (Diesel)
The start of saturation of the particle filter is
indicated by the temporary illumination of this
warning lamp accompanied by a message in
the instrument panel screen.As soon as the traffic conditions permit,
regenerate the filter by driving at a
speed of at least 25 mph (40 km/h) for
about 20 minutes (with the 1.6 litre HDi
engine the minimum speed is 36 mph
(60 km/h)).
If the warning lamp stays on, this
indicates a low additive level.
on a n

ew vehicle, the first particle
filter regeneration operations may be
accompanied by a "burning" smell,
which is per fectly normal.
Following prolonged operation of the
vehicle at very low speed or at idle,
you may, in exceptional circumstances,
notice the emission of water vapour at
the exhaust on acceleration. This does
not affect the behaviour of the vehicle
or the environment.
