seat cushion:
-

o
n the right-hand side, if the marking on
the ground has been crossed on the right,
-

o
n the left-hand side, if the marking on the
ground has been crossed on the left.
No warning is transmitted while the direction
indicator is active and for approximately
20 seconds after the direction indicator is
switched off.
A warning may be transmitted if a direction
marking (e.g. arrow) or non-standard marking
(e.g. graffiti) is crossed.
Operating fault
In the event of a malfunction, the service
warning lamp comes on, accompanied by an
audible signal and a message in the screen.
Contact a CITROËN dealer or a qualified

System which detects the involuntary crossing
of longitudinal traffic lane markings on the
ground (solid or broken line).
Sensors, fitted below the front bumper, trigger
a warning if the vehicle drifts over a lane
marking (speed higher than 50 mph (80 km/h)).
The detection may be impeded:- if the sensors are dirty (mud, snow...),- if the markings on the ground are worn,
- if there is little contrast between the
markings on the ground and the road
sur face.
The lane departure warning system
cannot in any circumstances replace
the need for vigilance on the part of

Checks

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 with an electric oil
level gauge, 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 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).
Checking using the dipstick
Refer to the "Petrol engine" or "Diesel engine"
section for the location of the dipstick in the
engine compartment of your vehicle.

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.

section for the location of the oil filler cap in the
engine compartment of your vehicle.

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.

workshop.
Coolant level
The coolant level should be close
to the "MA X" mark but should never
exceed it.
Changing the coolant
The coolant does not have to be replaced at routine services.
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 that the terminals are clean
and correctly tightened, particularly in summer
and winter.
The presence of this label, in particular with
the Stop & Start system, indicates the use of
a specific 12 V lead-acid battery with special
technology and specification. The involvement
of a CITROËN dealer or a qualified workshop
is essential when replacing or disconnecting
the battery. 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.
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. Refer to the manufacturer's
service schedule for details of the
replacement intervals for these
components.

Manual gearbox
The gearbox does not require any
maintenance (no oil change).
Automatic gearbox
The gearbox does not require any
maintenance (no oil change).

Refer to the manufacturer's service schedule

Particle filter system
(Diesel)
Complementary to the catalytic converter,
this filter makes an active contribution to the
preservation of air quality by trapping unburnt
pollutant particles. Black exhaust fumes are
thus no longer emitted.
After prolonged idling or driving at very low
speeds, you may occasionally notice water
vapour being emitted from the exhaust when
accelerating. This is of no consequence to the
running of the vehicle or to the environment.
If there is risk of blockage, a message
appears in the instrument panel screen,
accompanied by an audible signal and
illumination of the service warning lamp.
This alert tells you that the particle filter
is approaching saturation (in conditions
of urban driving of exceptionally long
duration: low speeds, traffic jams etc.)
To regenerate the filter, it is advised to
drive as soon as possible, when traffic
conditions permit, at a speed of 40 mph
(around 60 km/h) or more for at least
five minutes (until the alert message
disappears).
If this alert persists, contact a CITR
oËn


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