a message. A minor malfunction has
occurred for which there is
no specifi c warning lamp. Identify the malfunction by reading the
message displayed in the screen, such
as, for example:


- the opening of the doors, boot or
bonnet,

- the engine oil level,

- the remote control battery,

- the tyre pressures,

- saturation of the particle emission fi lter on
Diesel vehicles (see "Checks - § Checks/
Particle emissions fi lter").

For any other malfunctions, contact a
CITROËN dealer or a qualifi ed workshop.

fi xed,
accompanied by
a message and
an audible signal. A major malfunction has
occurred for which there is no

fi xed. The brake pedal is not
pressed. With the 6-speed electronic gearbox
system, press the brake pedal to start the

Engine oil level indicator
The vehicle must be on level
ground and the engine must
have been off for more than
30 minutes for this level check to
be accurate.
Oil level correct
This is indicated by the fl ashing of
"OIL"
or the display of a specifi c mes-
sage in the instrument panel, coupled
with the service warning lamp and ac-
companied by an audible signal.
If the low oil level is confi rmed by a
check using the dipstick, the level must
be topped up to avoid damage to the
engine.
Oil level indicator error

Dipstick
Refer to the "Checks" section to locate
the dipstick and the oil fi ller cap on your
engine.
Oil level incorrect This is indicated by the fl ashing of
"OIL--"
or the display of a specifi c mes-
sage in the instrument panel. Contact a
CITROËN or a qualifi ed workshop.
There are 2 marks on the
dipstick:


- A
= max; never exceed
this level (risk of dam-
age to the engine),

- B
= min; top up the level
via the oil fi ller cap, us-
ing the correct grade of
oil for your engine.

This information is displayed for a few
seconds when the ignition is switched
on, at the same time as the service in-
formation.

of the "activated"/"deactivated" status
of the confi gurable functions) and to
display the alerts log.

With the engine running, to start a
manual test, briefl y press the ".../000"

button on the instrument panel. The following information appears suc-
cessively in the instrument panel cen-
tral colour screen:


- engine oil level indicator (see corre-
sponding section),

- service indicator (see corresponding
section),

- under-infl ation detection (if your ve-
hicle is fi tted with this system; see
the "Safety" section),

- current warnings and alert messages,
if any (see corresponding section
for the warning lamp or system con-
cerned),

- status of confi gurable functions (see
"Multifunction screens").
This information also appears every
time the ignition is switched on (au-
tomatic test).

CHECKS

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 corre-
sponding system checked by a CITROËN
dealer or a qualifi ed workshop.

When working under the bon-
net, 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 igni-
tion is switched on using the oil level indicator
in the instrument panel, or using the dipstick.

Oil level


Engine oil change
Refer to the Maintenance and Warranty
Guide 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 Maintenance and Warranty
Guide 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 igni-
tion off.

On vehicles which are fi tted with a par-
ticle emission fi lter, the fan may operate
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.

CHECKS
175
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 corrosive.
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.
Additive level (Diesel with particle emissions filter)

According to your version of instrument
panel, the additive reservoir low level is
indicated by:

Topping up
The reservoir must be topped up with-
out delay by a CITROËN dealer or a
qualifi ed workshop.


- fi xed illumination of the par-
ticle emissions fi lter warning
lamp, accompanied by an au-
dible signal and a message
that the particle emissions fi l-
ter additive level is too low,

- fi xed illumination of the
service warning lamp, ac-
companied by an audible
signal and a message that
the particle emissions fi lter additive level is too low. or

Screenwash/headlamp washlevel

Specifi cation of the fl uid
To ensure optimum cleaning and to
avoid freezing, the fl uid should never be
topped up or replaced by plain water.


To check the level or top up the
fl uid on vehicle fi tted with head-
lamp washers, immobilise the
vehicle and switch of the engine.


)
Open the bonnet and secure it with
the stay.

)
Open the screenwash reservoir fi ller
cap.

)
Take and pinch the level gauge to
block its breather.

)
Remove the gauge completely from
the reservoir to read the level in the
transparent section.

)
Top up if necessary.

)
Refi t the fi ller cap to the reservoir
and close the bonnet.
