Coolant level
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.
Changing the coolant
X
The coolant does not have to be
changed.
Fluid specifi cation

manufacturer's recommendations.

with headlamp washers, the
low fl uid level is indicated
by an audible signal and a
message in the screen.
Top up the reservoir when you next
stop the vehicle.

filter)
A low additive level is indicated by
illumination of the service warning
lamp, accompanied by an audible

function screen.
Topping up
This additive must be topped up by
a CITROËN dealer or a qualifi ed

Used products
Avoid prolonged contact of
used oil or fl uids with the

Most of these fl uids are harmful to
health or indeed very corrosive.
Do not discard used oil or
fl uids into sewers or onto
the ground.
Take used oil to a CITROËN
dealer or a qualifi ed workshop
(France) or to an authorised waste
