Practical information
Engine compartment
The engine shown here is an example for
illustrative purposes only.
The locations of the following elements may
vary:
–
Air filter
.
–

Engine oil dipstick.
–


Engine oil filler cap.
Petrol engine

1. Screenwash fluid reservoir
2. Engine coolant reservoir
3. Brake fluid reservoir
4. Battery/Fuses
5. Remote earth point (-)
6. Fusebox
7. Air filter
8. Engine oil filler cap
9. Engine oil dipstick
Checking levels
Check all of the following levels regularly in
accordance with the manufacturer's service
schedule. Top them up if required, unless
otherwise indicated.
If a level drops significantly, have the
corresponding system checked by a CITROËN
dealer or a qualified workshop.
The fluids must comply with the
manufacturer's requirements and with
the vehicle's engine.
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).
Used products
Avoid prolonged contact of used oil or fluids with the skin.
Most of these fluids are harmful to health and
very corrosive.
Do not discard used oil or fluids into
sewers or onto the ground.
Empty used oil into the containers reserved
for this purpose at a CITROËN dealer or a
qualified workshop.
Engine oil
The level is checked, with the engine having been switched off for at least 30
minutes and on level ground, either using the oil
level indicator in the instrument panel when the
ignition is switched on (for vehicles equipped
with an electric gauge), or using the dipstick.
It is normal to top up the oil level between two
services (or oil changes). It is recommended
that you check the level, and top up if necessary,
every 3,000 miles (5,000 km).
In order to maintain the reliability of the
engine and emissions control system,
never use additives in the engine oil.
Checking using the dipstick
For the location of the dipstick, please refer
to the illustration of the corresponding engine
compartment.
►

Grasp the dipstick by its coloured grip and
pull it out completely

.
►

Wipe the end of the dipstick using a clean,
lint-free cloth.


► Reinsert the dipstick and push fully down,
then pull it out again to visually check the oil

159
Practical information
7level: the correct level is between marks A (max)
and B (min).
Do not start the engine if the level is:
–

above mark
A: contact a CITROËN dealer or a
qualified workshop.
–

below mark B

: top up the engine oil
immediately.
Oil grade
Before topping up or changing the
engine oil, check that the oil is suitable
for your engine and complies with the
recommendations in the service schedule
supplied with the vehicle (or available from
your CITROËN dealer or qualified workshop).
Use of non-recommended oil may invalidate
your 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 engine compartment
illustration.
►

Add oil in small quantities, avoiding any spills
on engine components (risk of fire).
►


W
ait a few minutes before checking the level
again using the dipstick.
►

T
op up the level if necessary.
►

After checking the level, carefully screw the
oil filler cap back on

and replace the dipstick in
its tube.
The oil level indication displayed on the instrument panel when the ignition is
switched on is not valid for 30 minutes
following an addition of oil.
Brake fluid
The level of this fluid should be close to
the "MAX" mark. If not, check the brake
pads for 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 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 level of coolant that is too low risks causing
major damage to the engine; the coolant level
must be close to the "MAX" mark without ever
going above 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 the
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 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.
Screenwash fluid
Top up to the required level when necessary.
Fluid specification
The fluid must be topped up with a pre-mixed
product.
In winter (temperatures below zero), a fluid
containing an anti-freeze agent which is
appropriate for the temperature conditions
must be used in order to protect the system's
components (pump, tank, ducts, jets).
Filling with pure water is prohibited in all
circumstances (risk of freezing,
limescale, etc.).
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.

160
Practical information
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.
Check regularly that the terminals are correctly
tightened (versions without quick-release
terminals) and that the connections are clean.
For more information on the precautions
to take before any work on the 12 V
battery, refer to the corresponding section.
Versions equipped with Stop & Start are
fitted with a 12 V lead-acid battery of
specific technology and specification.
Its replacement should be carried out only by
a CITROËN dealer or a qualified workshop.
Passenger compartment
filter
Depending on the environment and the
use of the vehicle (e.g. dusty atmosphere,
city driving), change it twice as often, if
necessary .
A clogged passenger compartment filter
can adversely affect air conditioning
system performance and generate
undesirable odours.
Air filter
Depending on the environment and the
use of the vehicle (e.g. dusty atmosphere,
city driving), change it twice as often, if
necessary .
Oil filter
Change the oil filter each time the engine
oil is changed.
Automatic gearbox
The gearbox does not require any
maintenance (no oil change).
Brake pads
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.
Unless there is a leak in the circuit, a drop in the
brake fluid level indicates that the brake pads
are worn.
After washing the vehicle, moisture, or in wintry conditions, ice can form on the
brake discs and pads: braking efficiency may
be reduced. Gently dab the brakes to dry and
defrost them.
Brake disc wear
For information on checking brake disc
wear, contact a CITROËN dealer or a
qualified workshop.
Electric parking brake
This system does not require any routine servicing. However, in the event of a
problem, do not hesitate to have the system
checked by a CITROËN dealer or a qualified
workshop.
For more information on the Electric
parking brake, refer to the
corresponding section.
Wheels and tyres
The inflation pressure of all tyres, including the spare wheel, must be
checked on "cold” tyres.
The pressures indicated on the tyre pressure
label are valid for "cold" tyres. If you have driven
for more than 10 minutes or more than 6 miles
(10 kilometres) at over 31 mph (50
km/h), add
0.3 bar (30 kPa) to the values indicated on the
label.
Under-inflation increases energy
consumption. Non-compliant tyre
