Warning and indicator
lamps
Displayed as symbols, the warning and indicator
lamps inform the driver of the occurrence of a
malfunction (warning lamps) or of the operating
status of a system (operation or deactivation
indicator lamps). Certain lamps light up in two
ways (fixed or flashing) and/or in several colours.
Associated warnings
The illumination of a lamp may be accompanied
by an audible signal and/or a message displayed
in a screen.
Relating the type of alert to the operating status
of the vehicle allows you to determine whether
the situation is normal or whether a fault has
occurred: refer to the description of each lamp
for further information.
When the ignition is switched on
Certain red or orange warning lamps come on
for a few seconds when the ignition is switched
on. These warning lamps should go off as soon
as the engine is started.
For more information on a system or a function,
refer to the corresponding section.
Warning lamp continuously
lit
The illumination of a red or orange warning lamp
may indicate the occurrence of a fault that needs
further investigation.
If a warning lamp remains lit
The references (1), (2) and (3) in the warning
and indicator lamp description indicate whether
you should contact a qualified professional in
addition to the immediate recommended actions.
(1): You must stop the vehicle .

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.
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.
Engine oil
The level is checked, with the engine having been switched off for at least 30
minutes and on level ground, using the dipstick.
To know how often the engine oil should be
replaced, refer to the manufacturer's servicing
schedule.
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
level: 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.

38
Practical information
– 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 the engine
and complies with the recommendations in
the service schedule 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).
►


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.
Within 30 minutes of adding oil, the oil
level indication in the instrument panel
when the ignition is switched on is not valid.
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.).

40
Practical information
The battery electrolyte must be filled. If the level
is found to be below the “MIN” level line, add
distilled water to the “MAX” level line.
For more information on the precautions
to take before any work on the 12 V
battery, refer to the corresponding section.
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.
Manual 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 and drum wear
For information on checking brake disc
and drum wear, contact a CITROËN
dealer.
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 10
kilometres at over 50 km/h, add 0.3 bar (30 kPa)
to the values indicated on the label.
Under-inflation increases fuel
consumption. Non-compliant tyre
pressure causes premature wear on tyres and
has an adverse effect on the vehicle's road
holding - risk of an accident!
Driving with worn or damaged tyres reduces the
braking and road holding performance of the
vehicle. It is recommended to regularly check the
condition of the tyres (tread and sidewalls) and
wheel rims as well as the presence of the valves.
When the wear indicators no longer appear set
back from the tread, the depth of the grooves is
less than 1.6 mm; it is imperative to replace the
tyres.
Using different size wheels and tyres from those
specified can affect the lifetime of tyres, wheel
rotation, ground clearance, the speedometer
reading and have an adverse effect on road
holding.
Fitting different tyres on the front and rear axles
can cause ABS and EBFD systems to mistime.
Shock absorbers
It is not easy for drivers to detect when
shock absorbers are worn. Nevertheless,
the shock absorbers have a major impact on
road-holding and braking performance.
For your safety and driving comfort, it is
important to have them regularly checked by a
CITROËN dealer.
