Deactivation
Going into engine START mode
At any time, press the "ECO OFF"
switch to deactivate the system.
This is confi rmed by the switch warning
lamp coming on accompanied by the
display of a message.
Special cases: START invoked
automatically
If the system has been deacti-
vated in STOP mode, the engine
restarts immediately. The "ECO"
warning lamp goes
off and the engine starts auto-
matically:
- with a manual gearbox
, when you
fully
depress the clutch pedal,
- with the 6-speed electronic gear-
box system
:
●
gear lever in position A
or M
, when
you release the brake pedal,
●
or gear lever in position N
and the
brake pedal released, when you
move the gear lever to position A
or M
,
●
or when you engage reverse gear.
For safety reasons or to ensure smooth
operation, START mode is invoked au-
tomatically when:
- you open the driver's door,
- you unfasten the driver's seat belt,
- the speed of the vehicle exceeds
15 mph (25 km/h) with a manual
gearbox or 7 mph (11 km/h) with the
6-speed electronic gearbox system,
- the electric parking brake is being
applied,
- some special conditions (battery
charge, engine temperature, brak-
ing assistance, ambient tempera-
ture...) where the engine is needed
to assure control of a system.
In this case the "ECO"
warning
lamp fl ashes for few seconds,
then goes off.
With a manual gearbox in STOP
mode, if a gear is engaged with-
out fully depressing the clutch
pedal, a warning lamp comes
on or an alert message is dis-
played asking you to depress
the clutch pedal to restart the
engine.
Reactivation
Press the "ECO OFF"
switch again.
The system is active again; this is con-
fi rmed by the switch warning lamp going
off and the display of a message.
The system is reactivated auto-
matically at every new start using
the key.
This operation is perfectly normal.

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.

to health or indeed very corro-
sive.

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 wash
level
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.
