Emergency braking


In the event of failure of the elec-
tronic stability control system,
signalled by the illumination of
this warning lamp, braking sta-
bility is then not guaranteed.
In this event, stability must be assured
by the driver by repeating alternate
"pull-release" actions on the control
lever A
.
In the event of a failure of the main
service brake or in an exceptional
situation (e.g. driver taken ill, under
instruction, etc) a continuous pull on
the control lever A
will stop the vehicle.
The electronic stability control provides
stability during emergency braking.
If the emergency braking malfunctions,
the message "Parking brake faulty" will
be displayed.
The emergency braking must
only be used in exceptional cir-
cumstances.










Emergency release

In the event of the electric parking brake
malfunctioning or the battery running
fl at, an emergency manual device can
release the parking brake.


)
Immobilise the vehicle (or keep
it stationary, if the brake pedal is
pressed), with the engine running,
by engaging fi rst gear (manual gear-
box), position P
(automatic gear-
box) or position M
or R
(6-speed
electronic gearbox system).

)
Switch off the engine but leave the
ignition on. If it is not possible to im-
mobilise the vehicle, do not operate
the control and contact a CITROËN
dealer or a qualifi ed workshop with-
out delay.

LANE DEPARTURE WARNING
SYSTEM
The lane departure warning sys-
tem cannot, in any circumstances,
replace the need for vigilance and
responsibility on the part of the
driver.

Activation



)
Press this button, the indicator lamp
comes on.



Deactivation



)
Press this button again, the indicator
lamp goes off.
The status of the system remains in the
memory when the ignition is switched
off.


Detection

You are warned by the vibration of the
driver's seat cushion:


- on the right-hand side, if the mark-
ing on the ground has been crossed
on the right,

- on 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 di-
rection indicator is switched off.
A warning may be transmitted if a direc-
tion marking (e.g. arrow) or non-standard
marking (e.g. graffi ti) is crossed.


Operating fault


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 be-
tween the markings on the
ground and the road surface.

System which detects the involuntary
crossing of longitudinal traffi c lane mark-
ings on the ground (solid or broken
line).
Sensors, fi tted below the front bumper,
trigger a warning if the vehicle drifts
over a lane marking (speed higher than
50 mph (80 km/h)).
This system is particularly useful on
motorways and main roads. 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 qualifi ed
workshop.

CHECKING LEVELS

Check all of these levels regularly and
top them up if necessary, unless other-
wise indicated.
If a level drops signifi cantly, have the
corresponding system checked by a
CITROËN dealer or a qualifi ed work-
shop.

When working under the bonnet,
take care, as certain areas of the
engine may be extremely hot (risk
of burns).
The reading will only be correct if
the vehicle is on level ground and
the engine has been off for more
than 30 minutes.
The check is carried out either when the
ignition is switched on using the oil level
indicator in the instrument panel, or using
the dipstick.
It is normal to top up the oil level between
two services. CITROËN recommends that
you check the oil level, and top up if neces-
sary, every 3 000 miles (5 000 kilometres).

Oil level


Engine oil change
Refer to the servicing booklet for the
interval for this operation.
In order to maintain the reliability of the
engine and emission control system,
the use of additives in the engine oil is
prohibited.
Oil specifi cation
The oil must correspond to your engine
and conform to the manufacturer's rec-
ommendations.



Brake fluid level

The brake fl uid level should be
close to the "MAX" mark. If it is
not, check the brake pad wear.

Changing the fl uid
Refer to the servicing booklet for the
interval for this operation.

Fluid specifi cation
The brake fl uid must conform to the
manufacturer's recommendations and
meet the DOT4 standard.



Power steering fluid level

The power steering fl uid level
should be close to the "MAX"
mark. Unscrew the cap, with
the engine cold, to check the
level.


Coolant level

The coolant level should be
close to the "MAX" mark but
should never exceed it.
When the engine is warm, the
temperature of the coolant is regulated
by the fan. This can operate with the ig-
nition off.

On vehicles which are fi tted with a par-
ticle emission fi lter, the fan may oper-
ate after the vehicle has been switched
off, even if the engine is cold.
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 pres-
sure to drop. When the pressure has
dropped, remove the cap and top up
the level.

Changing the coolant
The coolant does not have to be
changed.

Coolant specifi cation
The coolant must conform to the manu-
facturer's recommendations.

Used products

Avoid prolonged contact of used
oil or fl uids with the skin.
Most of these fl uids are harmful
to health or indeed very corro-
sive.
Do not discard used oil or fl uids
into sewers or onto the ground.
Take used oil to a CITROËN
dealer or a qualifi ed workshop
(France) or to an authorised
waste disposal site.

CHECKS

Unless otherwise indicated, check
these components in accordance with
the servicing booklet and according to
your engine.
Otherwise, have them checked by a
CITROËN dealer or a qualifi ed workshop.


Battery

The battery does not require
any maintenance.
However, check that the ter-
minals are clean and correctly
tightened, particularly in sum-
mer and winter.
When carrying out work on the battery,
refer to the "Practical information" sec-
tion for details of the precautions to be
taken before disconnecting the battery
and following its reconnection.


Air filter and passenger compartment filter

Refer to the servicing booklet
for details of the replacement
intervals for these compo-
nents.

Oil filter

Replace the oil fi lter each time
the engine oil is changed.
Refer to the servicing booklet
for details of the replacement
interval for this component.










Particle emission filter (Diesel)

According to your version of instrument
panel, the start of saturation of the par-
ticle emissions fi lter is indicated by:


- fi xed illumination of the par-
ticle emissions fi lter warning
lamp, accompanied by an au-
dible signal and a message
that there is a risk of blockage
of the particle emissions fi lter,






The presence of this label, in particular
with the Stop & Start system, indicates
the use of a specifi c 12 V lead-acid bat-
tery with special technology and speci-
fi cation, for which the involvement of a
CITROËN dealer or a qualifi ed work-
shop is required when replacing or dis-
connecting the battery.
Failure to observe this recommendation
may shorten the life of the battery.

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
(refer to
the "Engines" section).
A clogged passenger compartment fi l-
ter may have an adverse effect on the
performance of the air conditioning sys-
tem and generate undesirable odours.
As soon as the traffi c conditions per-
mit, regenerate the fi lter 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, refer to
the "Additive level" section.
On a new vehicle, the fi rst opera-
tions of regeneration of the particle
emissions fi lter may be accom-
panied by the smell of "burning",
which is perfectly normal.
Following prolonged operation
of the vehicle at very low speed
or at idle, you may, in excep-
tional circumstances, notice the
emission of water vapour at the
exhaust on acceleration. This
does not affect the behaviour of
the vehicle or the environment. or

-
temporary illumination of
the service warning lamp,
accompanied by an audible
signal and a message that
there is a risk of blockage of
the particle emissions fi lter.

brake must be checked, even
between two services.
Checking this system must be
done by a CITROËN dealer or a quali-
fi ed workshop.

















Only use products recommended
by CITROËN or products of equiv-
alent quality and specifi cation.

In order to optimise the opera-
tion of units as important as
the braking system, CITROËN
selects and offers very specifi c
products.
To avoid damaging the electrical
units, the use of a high pressure
washer in the engine compart-
ment is strictly prohibited
.



Manual parking brake

For information on checking
brake disc wear, contact a
CITROËN dealer or a quali-
fi ed workshop. 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 system, a drop
in the brake fl uid level indicates that the
brake pads are worn.
