one of the airbag or seat belt
pretensioner systems.
Maximum coolant temperature
If this comes on, it indicates
that the temperature in the
cooling system is too high.
Stop the vehicle as soon as
it is safe to do so.
Low fuel level When the tank is full, all the
bars are lit up.
If the fuel low warning lamp comes on
accompanied by an audible signal and
a message on the multifunction screen,
there are approximately 7 litres of fuel
remaining in the tank and 2 or 3 bars
fl ash in the instrument panel.

A control located on the panel to the
left of the steering wheel allows you
to open the fuel fl ap from inside the

ing warning lamp will only come on
if the seat is occupied and the seat
belt not fastened.

- the warning lamp lights up be-
tween 0 and 20 km/h. Above
20 km/h (approx.12 mph), it

sage on the multifunction screen
and an audible signal for around
120 seconds.

CHECKING LEVELS
Check all of these levels regularly
and top them up if necessary, unless
otherwise indicated.
If a level drops signifi cantly, have the
corresponding system checked by a
CITROËN dealer.
Oil level
Oil change
Refer to the Maintenance and
Warranty Guide for details of the in-
terval for this operation. Oil specifi cation
The oil must correspond to your en-
gine and conform to the manufactur-
er's recommendations.
Brake fluid level
Fluid change
Refer to the Maintenance and
Warranty Guide for details of the in-
terval for this operation.
This fl uid must be changed regu-
larly. Fluid which has been used for
too long may cause a loss of braking
effi ciency.
Fluid specifi cation
The brake fl uid must conform to the
manufacturer's recommendations
and fulfi l the DOT4 standards.
Coolant level
Draining the system
The coolant does not have to be
changed.
Fluid specifi cation
The coolant must conform to the
manufacturer's recommendations.
The reading will only be
correct if the vehicle is on
level ground and the engine
has been off for more than
15 minutes.
The check is carried out either when
the ignition is switched on using the
oil level indicator on the instrument
panel, or using the dipstick.
Between two oil changes, the con-
sumption should not exceed 0.5 litre
per 600 miles (approx. 1 000 km).
Check this level also between each
scheduled service and before long
journeys. The brake fl uid level should
be close to the "MAX" mark.
If it is not, check the brake
pad wear.
The coolant level should be
close to the "MAX" mark but
should never exceed it.
When the engine is warm,
the temperature of the coolant is
regulated by the fan. This can oper-
ate with the ignition off.

On vehicles which are fi tted with
a particle emission fi lter, the fan
may operate after the vehicle has
been switched off, even if the en-
gine is cold.
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, un-
screw the cap by two turns to al-
low the pressure to drop. When the
pressure has dropped, remove the
cap and top up the level.
In order to maintain the re-
liability of the engine and
emission control system,
the use of additives in the engine
oil is prohibited.
