fill the tank.
In order to ensure a good flow of fuel,
do not place the nozzle of the fuel can

misfuel prevention device and pour

Misfuel prevention (Diesel)*
Mechanical device which prevents filling the tank of a Diesel vehicle with petrol. It avoids the risk of
engine damage that can result from filling with the wrong fuel.
Located in the filler neck, the misfuel prevention device appears when the filler cap is removed.
When a petrol filler nozzle is introduced into the
fuel filler neck of your Diesel vehicle, it comes
into contact with the flap. The system remains
closed and prevents filling.

Operation
Travelling abroad
As Diesel fuel pump nozzles may
be different in other countries, the
presence of the misfuel prevention
device may make refuelling impossible.
Not all Diesel vehicles are fitted with
misfuel protection, so before travelling
abroad, we recommend that you check
with the CITROËN dealer network,
whether your vehicle is suitable for the
fuel pumps in the country in which you
intend to travel.

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).
Engine oil level
The check is carried out either when
the ignition is switched on using the
oil level indicator in the instrument
panel for vehicles so equipped, or
using the dipstick.
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 kms). To ensure that the reading is correct,
your vehicle must be parked on a level
sur face with the engine having been off
for more than 30 minutes.
Check all of these levels regularly, in line with the manufacturer's service schedule. 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.checking using the

If you find that the level is above the A mark or
below the B mark, do not star t the engine .
-
If t

he level is above the MAX mark (risk
of damage to the engine), contact a
CITROËN dealer or a qualified workshop.
-
If t

he level is below the MIN mark, you
must top up the engine oil.

Power steering fluid
level
The power steering fluid level should
be close to the "MA X" mark. With
the engine cold, unscrew the cap to
check the level. The brake fluid level should be close
to the "MA X" mark. If it is not, check
the brake pad wear.

Changing the fluid
Refer to the manufacturer's service schedule
for details of the interval for this operation.
Fluid specification
The brake fluid must conform to the
manufacturer's recommendations.
Oil grade
Before topping-up the oil or changing the oil,
check that the oil is the correct grade for your
engine and conforms to the manufacturer's
recommendations.

switching on the ignition with the oil level
indicator in the instrument panel is not valid
during the 30 minutes after topping up.
Engine oil change
Refer to the manufacturer's service schedule
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.

coolant level
The coolant level should be close
to the "MA X" mark but should never
exceed it.
Fluid specification
The coolant must conform to the
manufacturer's recommendations.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.
When the engine is warm, the temperature of
the coolant is regulated by the fan.
The cooling fan may star t after switching
off the engine: take care with ar ticles and
clothing that might be caught by the fan
blades.
Specification of the fluid
To ensure optimum cleaning and to avoid
freezing, the fluid should never be topped up or
replaced by plain water.
In wintry conditions, the use of an ethyl alcohol
or methanol base fluid is recommended.
