Checks
Coolant level
The coolant level must be:
- between the "FULL" or "F" and
"LOW" or "L" marks for VTi 68
and VTi 68 S&S engines,
between the "MIN" and "MAX" marks for
-
the PureTech 82 engine.
When the engine is warm, the temperature of
the coolant is regulated by the fan.
The cooling fan may start after switching
off the engine: take care with articles and
clothing that might be caught by the fan
blades.
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.

Screenwash fluid level
Top up the level when necessary.
Fluid specification
For optimum cleaning and to avoid freezing,
this fluid must not be topped up or replaced
with plain water.
In wintry conditions, it is recommended that you
use an ethyl alcohol or methanol based fluid.
Used products
Avoid prolonged contact of used oil or
fluids with the skin.
Most of these fluids are harmful to
health or indeed very corrosive.
Do not discard used oil or fluids into
sewers or onto the ground.
Take used oil to a CITROËN dealer or
a qualified workshop (France) or to an
authorised waste disposal site.
