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.
Check all of these levels regularly, in line with the manufacturer's service schedule. 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.
If you find that the level is above the A mark or
below the B mark, do not star t the engine.
-

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

I
f the level is below the MIN mark, you
must top-up the engine oil.
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 sur face
with the engine having been off for more than
30
m

inutes.
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).
Checking using the dipstick
The location of the dipstick is shown in the
corresponding underbonnet layout view.

the correct level is between the marks A
and B .
A = MA X
B = MIN

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.
Topping-up the engine oil level
The location of the oil filler cap is shown in the
corresponding underbonnet layout view.

aperture.

level again using the dipstick.

fter 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.

Brake fluid level
The brake fluid level should be close
to the "MA X" 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.
Power steering or power
steering and suspension
fluid level
For topping up, it is necessary to go
to a CITROËN dealer or a qualified
workshop.
Coolant level
The coolant level should be close
to the "MA X" mark but should never
exceed it.
Fluid specification
The coolant must conform to the
manufacturer's recommendations. The cooling fan may star t after switching
off the engine: take care with ar ticles 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. When the engine is warm, the temperature of
the coolant is regulated by the fan.

Checks
12 V battery
The battery does not require any
maintenance.
However, check regularly that the terminals are
correctly tightened (versions without quick release
terminals) and that the connections are clean.
Unless other wise indicated, check these components in accordance with the manufacturer's service schedule and according to your engine.
Other wise, have them checked by a CITROËN dealer or a qualified workshop.
Air filter and passenger compartment filter
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 per formance
of the air conditioning system and generate
undesirable odours. Replace the oil filter each time the
engine oil is changed.
Oil filter
Refer to the manufacturer's service schedule
for details of the replacement interval for this
component.
Refer to the manufacturer's
service schedule for details of the
replacement intervals for these
components.
For more information and the precautions to
take before starting work on the 12 V batter y ,
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.

In the event of a fault with the SCR emissions control system
These warning lamps come on, accompanied
by an audible signal and the display of the
message "Emissions fault".
The alert is triggered when driving when the
fault is detected for the first time, then when
switching on the ignition for subsequent
journeys, while the fault persists.If it is a temporary fault, the alert
disappears during the next journey,
after self-diagnosis of the SCR system.
During an authorised driving phase (between
650 miles and 0 miles) (1 100 km and 0 km)A system that prevents engine starting
is activated automatically from
650 miles (1 100 km) after confirmation
of a fault with the SCR emissions
control system. Have the system
checked by a CITROËN dealer or a
qualified workshop as soon as possible. In the event of the detection of a fault
If a fault with the SCR system is confirmed
(after 30 miles (50 km) covered with the
permanent display of the message signalling
a fault), these warning lamps come on,
accompanied by an audible signal and the
display of a message (e.g.: "Emissions fault:
Starting prevented in 150 miles") indicating
the remaining range expressed in miles or
kilometres.
While driving, the message is displayed every
30 seconds while the fault with the SCR system
persists.
The alert is repeated when switching on the
ignition.
You should go to a CITROËN dealer or a
qualified workshop as soon as possible.
Other wise, you will not be able to restart your
engine.

First check that the slave battery has a
nominal voltage of 12 V and a capacity
at least equal to that of the discharged
battery.
The two vehicles must not be in contact
with each other.
Switch off the electrical consumers on
both vehicles (audio system, wipers,
lighting, ...).
Ensure that the jump lead cables do
not pass close to moving parts of the
engine (cooling fan, belts, ...).

QUESTIONANSWER SOLUTION
There is a difference in
sound quality between the
different audio sources. For optimum sound quality, the audio settings for Volume, Bass,
Treble, Equalizer and Loudness can be adapted to the different
sound sources, which may result in audible differences when
changing source. Check that the audio settings for (Volume, Bass,
Treble, Equalizer, Loudness) are adapted to the
sources listened to. It is advisable to set the
audio functions (Bass, Treble, Fr-Re balance,
Le-Ri balance) to the middle position, select the
"Linear", musical ambience and set the loudness
correction to the "Inactive" position in radio mode.
With the engine off, the
system switches off after a
few minutes of use. When the engine is switched off, the system's operating time
depends on the state of charge of the battery.
The switch-off is normal: the system switches to economy mode and
switches off to prevent discharging of the vehicle's battery. Start the vehicle's engine to increase the battery
charge.

The message "the audio
system is overheated"
appears on the display. In order to protect the installation if the surrounding temperature
is too high, the audio system switches to an automatic thermal
protection mode leading to a reduction in volume or CD play
stopping. Switch the audio system off for a few minutes to
allow the system to cool.
