Practical information
supplied with the vehicle (or available from
your CITROËN dealer).
Use of non-recommended oil may invalidate
the contractual warranty in the event of
engine failure.
Topping up the engine oil level
For the location of the engine oil filler cap,
please refer to the corresponding under-bonnet
engine compartment illustration.
► Add oil in small quantities, avoiding any spills
on engine components (risk of fire).
► Wait a few minutes before checking the
level again using the dipstick.
► Top up the level if necessary.
► After checking the level, carefully screw the
oil filler cap back on and replace the dipstick in
its tube.
Brake fluid
The level of this fluid should be close to
the "MAX" mark. If not, check the
leakage in the circuit and the brake pad wear.
To know how often the brake fluid should be
replaced, refer to the manufacturer's servicing
schedule.
Clean the cap before removing it to
refill. Use only DOT3 or DOT4 brake
fluid from a sealed container.

Engine 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 engine coolant 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
engine coolant 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 burning, 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.
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.).
