CITROEN C4 CACTUS 2016 Handbook page 175

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.
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.
Changing the coolant
The coolant does not have to be replaced at routine services.
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.
Diesel fuel additive
level (Diesel with particle
filter)
The additive reservoir low level is
indicated by fixed illumination of
this warning lamp, accompanied by an audible
signal and a message that the particle filter
additive level is too low.
Topping up
The reservoir must be topped up without delay
by a CITROËN dealer or a qualified workshop.
Practical information
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.
