Checks
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.


1.
Opening the filer flap.

2.
Removing the filler cap.

3.
Hooking the filler cap.
To fill the tank safely:


)
the engine must be switched off,


)
pull the control A
located at the bottom
right of the driver's seat to release the fuel
filler flap,

)
open the fuel filler flap B
,

)
turn the filler cap C
to the left,

)
remove the filler cap C
,

)
fill the tank, but do not continue after the
3rd cut- off of the nozzle
; this could cause
malfunctions.
When you have filled the tank:


)
refit the filler cap, inserting the upper part
first,

)
screw in the filler cap to the right,

)
close the flap.
Ensure that the fuel filler flap is closed
correctly. This symbol indicates that the fuel
tank cap is located on the left-hand
side of the vehicle.
Opening the cap may cause an inrush of air.
This vacuum, which is completely normal, is
caused by the sealing of the fuel system. The symbol flashes slowly
(approximately
once per second).

Checks










Quality of the fuel used for
petrol engines

The petrol engines are per fectly compatible
with E10 or E24 type petrol biofuels
(containing 10 % or 24 % 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 ser vicing 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






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 inter val for this operation.
In order to maintain the reliability of the engine
and emission control system, the use of
additives in the engine oil is prohibited.


Oil specifi cation

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 ser vices (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.

220
Checks










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 specifi cation

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 fl uid

Refer to the maintenance and warranty guide
for details of the inter val for this operation.


Fluid specifi cation

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.
