Checks

145

C3Picasso_en_Chap10_verification_ed01-2015

Checking levels

Engine oil level

The check is carried out either when
the ignition is switched on using the
oil level indicator in the instrument
panel for vehicles so equipped, or
using the dipstick.

Checking using the dipstick

A = MAX

Check all of these levels regularly, in line with the manufacturer's service schedule. Top them up if necessary, unless otherwise indicated.
If a level drops significantly, have the corresponding system checked by a CITROËN dealer or a qualified workshop.

Take care when working under the
bonnet, as certain areas of the engine
may be extremely hot (risk of burns)
and the cooling fan could start at any
time (even with the ignition off).

To ensure that the reading is correct,
your vehicle must be parked on a level
surface with the engine having been off
for more than 30 minutes.

It is normal to top up the oil level between
two services (or oil changes). CITROËN
recommends that you check the level, and top
up if necessary, every 3 000 miles (5 000 kms).

B = MIN

If you find that the level is above the A mark or
below the B mark, do not start the engine.
-

If the level is above the MAX mark (risk
of damage to the engine), contact a
CITROËN dealer or a qualified workshop.

- If the level is below the MIN mark, you

must top up the engine oil.

Oil grade

Before topping-up the oil or changing the oil,
check that the oil is the correct grade for your
engine and conforms to the manufacturer's
recommendations.

F Locate the dipstick in the engine

compartment of your vehicle.

For more information on the petrol or Diesel
engine, refer to the corresponding section.
F Take the dipstick by its coloured grip and

remove it completely.

F Wipe the end of the dipstick using a clean

non-fluffy cloth.

F

Refit the dipstick and push fully down, then

pull it out again to make the visual check:
the correct level is between the marks A
and B.

C3Picasso_en_Chap10_verification_ed01-2015

Brake fluid level

The brake fluid level should be close
to the "MAX" mark. 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.

Topping-up the engine oil level

F Locate the oil filler cap in the engine

compartment of your vehicle.

For more information on the petrol or Diesel
engine, refer to the corresponding section.
F

Unscrew the oil filler cap to reveal the filler

aperture.

F Add oil in small quantities, avoiding any

spills on engine components (risk of fire).

F

Wait a few minutes before checking the

level again using the dipstick.

F Add more oil if necessary.
F After checking the level, carefully refit the

oil filler cap and the dipstick in its tube.

After topping-up the oil, the check when
switching on the ignition with the oil level
indicator in the instrument panel is not valid
during the 30 minutes after topping up.

Engine oil change

Refer to the manufacturer's service schedule
for details of the interval for this operation.
In order to maintain the reliability of the engine
and emission control system, never use
additives in the engine oil.

Checks

147

C3Picasso_en_Chap10_verification_ed01-2015

Coolant level

The coolant level should be close
to the "MAX" mark but should never
exceed it.

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.

Coolant specification

The coolant must conform to the
manufacturer's recommendations.

Screenwash fluid level

When the engine is warm, the temperature of
the coolant is regulated by the fan.

Top up the level when necessary.

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.

Diesel additive level (Diesel
engine with particle filter)

Used products

Topping up

This additive must be topped up by a CITROËN
dealer or a qualified workshop without delay.

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.

The additive reservoir low
level is indicated by fixed
illumination of this warning lamp,
accompanied by an audible
warning and a message in the
multifunction screen.

Checks

148

C3Picasso_en_Chap10_verification_ed01-2015

Particle filter (Diesel)

The start of saturation of the
particle filter is indicated by

the temporary illumination of this warning lamp
accompanied by a message in the multifunction
screen.
As soon as the traffic conditions permit, regenerate
the filter by driving at a speed of at least 40 mph
(60 km/h) until the warning lamp goes off.
If the warning lamp stays on, this indicates a low
additive level.
For more information on checking levels, refer to
the corresponding section.

On a new vehicle, the first particle
filter regeneration operations may be
accompanied by a "burning" smell,
which is perfectly normal.
Following prolonged operation of the
vehicle at very low speed or at idle,
you may, in exceptional circumstances,
notice the emission of water vapour at
the exhaust on acceleration. This does
not affect the behaviour of the vehicle
or the environment.

Checks

12 V battery

The battery does not require any maintenance.
However, check that the terminals are clean
and correctly tightened, particularly in summer
and winter.

Air filter and passenger compartment filter

Refer to the manufacturer's
service schedule for details of the
replacement intervals for these
components.

Oil filter

Replace the oil filter each time the
engine oil is changed.
Refer to the manufacturer's
service schedule for details of
the replacement interval for this
component.

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.

When carrying out work on the battery, refer
to the "12 V battery" section for details of the
precautions to be taken before disconnecting
the battery and following its reconnection.

Depending on the environment (e.g. dusty
atmosphere) and the use of the vehicle
(e.g. city driving), replace them twice as often
if necessary.
A clogged passenger compartment filter may
have an adverse effect on the performance
of the air conditioning system and generate
undesirable odours.

Parking brake

If excessive travel or a loss of
effectiveness of this system is
noticed, the parking brake must be
checked, even between two services.

Manual gearbox

The gearbox does not require any
maintenance (no oil change).
Refer to the manufacturer's service
schedule for the checking interval for
this component.

For information on checking brake
disc wear, contact a CITROËN dealer
or a qualified workshop.

Brake disc wear

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

The gearbox does not require any
maintenance (no oil change).
Refer to the manufacturer's service
schedule for details of the checking
interval for this component.

Electronic gearbox

Only use products recommended by
CITROËN or products of equivalent
quality and specification.
In order to optimise the operation of
units as important as those in the
braking system, CITROËN selects and
offers very specific products.
After washing the vehicle, dampness,
or in wintry conditions, ice can form
on the brake discs and pads: braking
efficiency may be reduced. Make light
brake applications to dry and defrost
the brakes.

Checking this system must be done 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.

Composition of the kit

1.

12 V compressor, with integral pressure

gauge.

2.

Sealant cartridge, with integral hose.

3. Speed limit sticker.

Access to the kit

This kit is installed in the storage box, under the
boot floor.

The speed limit sticker must be secured
to the interior of the vehicle in the
driver's field of vision, to remind you
that a wheel is in temporary use.

Comprising a compressor and a sealant
cartridge, it allows the temporary repair of
a tyre so that you can drive to the nearest
garage.
It is designed to repair most punctures which
could affect the tyre, located on the tyre tread
or shoulder.

Do not exceed a speed of 50 mph
(80 km/h) when driving with a tyre
repaired using this type of kit.

The vehicle's electric system allows the
connection of a compressor for long
enough to inflate a tyre after a puncture
repair or for inflating a small inflatable
accessory.
