2021 CITROEN C3 AIRCROSS coolant level

133
Practical information
7Engine coolant
It is normal to top up this fluid between two services.
The check and top-up must only be done with
the engine cold.
A low level presents a risk of serious damage to
the engine.
The level of this fluid should be close to the
"MAX" mark but should never exceed it.
If the level is close to or below the " MIN” mark, it
is essential to top up.
When the engine is hot, the temperature of this
fluid is regulated by the fan.
As the cooling system is pressurised, wait at
least one hour after switching off the engine
before carrying out any work.
In order to avoid the risk of scalding if you need
to top up in an emergency, wrap a cloth around
the cap and unscrew the cap by two turns to
allow the pressure to drop.
Once the pressure has dropped, remove the cap
and top up to the required level.
Cooling of the engine when stopped
The engine cooling fan may start after
the engine has been switched off.
Take care with objects or clothing that
could be caught in the blades of the fan!
Screenwash fluid
Top up to the required level when necessary.
Fluid specification
The fluid must be topped up with a ready-to-use
mixture.
In winter (temperatures below zero), a liquid
containing an agent to prevent freezing must
be used which is appropriate for the prevailing
conditions, in order to protect the elements of the
system (pump, tank, ducts, jets, etc.).
Filling with pure water is prohibited under
all circumstances (risk of freezing,
limestone deposits, etc.).
Diesel fuel additive (Diesel
with particle filter)
On reaching the minimum level in the particle filter additive tank, this warning
lamp comes on fixed, accompanied by an
audible warning and a message warning that the
additive level is too low.
Topping up
This additive must be topped up without delay by
a CITROËN dealer or a qualified workshop.
AdBlue (BlueHDi)
An alert is triggered when the reserve level is
reached.
For more information on the AdBlue range
indicators, refer to the corresponding section.
To avoid the vehicle being immobilised in
accordance with regulations, you must top up the
AdBlue tank.
For more information on the Supply of AdBlue,
refer to the corresponding section.
Checks
Unless otherwise indicated, check these
components in accordance with the
manufacturer's service schedule and according
to your engine.
Otherwise, have them checked by a CITROËN
dealer or a qualified workshop.
Only use products recommended by
CITROËN or products of equivalent
quality and specification.
In order to optimise the operation of
components as important as those in the
braking system, CITROËN selects and offers
very specific products.
12 V battery
The battery does not require any maintenance.
However, check regularly that the terminals
are correctly tightened (versions without quick
release terminals) and that the connections are
clean.
