Checking levelsCheck all of these levels regularly and top them up if necessary, unless other wise indicated.
If a level drops significantly, have the corresponding system checked by a CITROËN dealer or a qualified workshop.Never do anything in the compartments
when the "Ready" lamp is on or when
your vehicle is being charged.
Take care when carrying out checks
in the front and rear compartments as
some parts of the compartments can
be very hot (risk of burns): wait at least
one hour after stopping the motor or the
end of the charging procedure before
carrying out any work.
Brake fluid level
The brake fluid level should be
between the "MIN" and "MA X"
marks. If it is not, check the brake
pad wear.
Changing the fluid
Refer to the manufacturer's service schedule
for details of the interval for this operation.
Fluid specification
The brake fluid must conform to the
manufacturer's recommendations.
Front compartment Heating system fluid level
Changing the fluid
This fluid does not have to be changed.
Fluid specification
The fluid must conform to the manufacturer's
recommendations. The level of this fluid should be between
the "L" MIN and "F" MA X marks.
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.

The coolant level should be between
the MIN "L" and MA X "F" marks.
Coolant levelAvoid prolonged contact of used fluids
with the skin.
Most of these fluids are harmful to
health and some are very corrosive.
Do not discard used fluids into sewers
or onto the ground.
Take used fluids to a CITROËN dealer
or a qualified workshop (France) or to
an authorised waste disposal site.
Used products
Rear compartment
Changing the coolant
The coolant does not have to be changed.
Coolant specification
The coolant must conform to the
manufacturer's recommendations. As the cooling system is pressurised, wait at
least one hour after switching off the motor
and/or the end of the charging cycle 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.
12 V battery electrolyte
level
Remove the battery protective cover to check
this level.
For more information on the 12 V battery, refer
to the corresponding section.
The level of this fluid should be between the
MIN "LOWER LEVEL" and MA X "UPPER
LEVEL" marks.
If necessary, top up using distilled water by
removing the caps of the different battery
compartments.
Check the electrolyte level at least once
per month.

111
Checking componentsUnless other wise indicated, check these components in accordance with the manufacturer's service schedule.
Other wise, have them checked by a CITROËN dealer or a qualified workshop.
Passenger compartment filter
Refer to the manufacturer's
service schedule for details of the
replacement intervals for this filter.
Brake wear depends on the style
of driving, particularly in the case
of vehicles used in town, over short
distances. It may be necessary to have
the condition of the brakes checked,
even between vehicle services.
Brake pads
Only use products recommended by
CITROËN or products of equivalent
quality and specifications.
In order to optimise the operation
of units as important as the braking
system, CITROËN selects and offers
very specific products.
Parking brake
If a loss of effectiveness of this
system is noticed, the parking brake
must be checked, even between
two services.
Brake disc / drum wear
For information on checking the
brake disc or drum wear, contact
a CITROËN dealer or a qualified
workshop.
This system must be checked by a CITROËN
dealer or a qualified workshop.
Unless there is a leak in the circuit, a drop in
the brake fluid level indicates that the brake
pads are worn. Depending on the environment (e.g. dusty
atmosphere) and the use of the vehicle
(e.g.

city driving), replace it twice as often
if necessary .
A dirty passenger compartment filter may have
an adverse effect on the per formance of the air
conditioning system and generate undesirable
odours.

Precautions for
washing
To avoid damaging the electrical
components, the use of a high pressure
jet wash is strictly prohibited:
-

i
n the front compartment (under the
bonnet).
-

u
nder the body.
For washing the bodywork, do not use a
pressure greater than 80 bars. Check - before washing the vehicle -
that the charging flaps and the charging
socket covers (normal and fast charge)
are properly closed. Do not wash the vehicle while the
battery is being recharged.
Practical information

113
12 V battery
All of the electrical components of your vehicle
(other than the electric motor, the heating and
the air conditioning) are powered by this 12 V
ancillaries battery.
It is located in the front compartment and is
recharged by the main battery, during phases
of operation ("Ready" lamp on in the instrument
panel) and charging.If the 12 V battery is discharged, it will
not be possible to start the motor and
the main battery cannot be charged. F

Disconnecting the battery is not
recommended.
However, if the vehicle is not to be used
for a prolonged period of more than a
month, it may be necessary, in winter,
to disconnect and store the battery to
avoid the electrolyte freezing.
After prolonged disconnection of the
battery, you must contact a CITROËN
dealer or a qualified workshop to have
the electronic control unit reinitialised.
