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 warn-
ing lamp coming on accompanied by a
message on the screen.
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:


- with a manual gearbox
, when you
depress the clutch pedal,

- with the 6-speed electronic gearbox
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.

START is invoked automatically 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 a message is displayed
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 go-
ing off and a message in the instrument
panel.
The system is reactivated auto-
matically at every new start using
the key.
This operation is perfectly normal.

CHECKS
179
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 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.

CHANGING A WIPER BLADE

Before removin
g a front wiper blade



)
Within one minute after switching off
the ignition, operate the wiper stalk
to position the wiper blades verti-
cally on the windscreen.



Removing



)
Raise the corresponding wiper arm.

)
Unclip the wiper blade and remove it.



Fitting



)
Put the corresponding new wiper
blade in place and clip it.

)
Fold down the wiper arm carefully.



After fitting a front wiper blade



)
Switch on the ignition.

)
Operate the wiper stalk again to
park the wiper blades.

VERY COLD CLIMATE SCREEN *


*
According to country.


Fitting



)
Offer up the very cold climate screen
to the front of the lower section of
the front bumper.

)
Press around its edge to engage its
fi xing clips one by one.

Removal



)
Use a screwdriver as a lever to re-
lease each fi xing clip in turn.
Do not forget to remove the very
cold climate screen:


- when the ambient temperature
exceeds 10 °C,

- when towing,

- at speeds above 75 mph
(120 km/h).
Removable protective screen which
prevents the accumulation of snow at
the radiator cooling fan.

PRACTICAL INFORMATION
208
TOWING A TRAILER,
A CARAVAN, ETC.
We recommend the use of genu-
ine CITROËN towbars and their
harnesses that have been tested
and approved from the design
stage of your vehicle, and that
the fi tting of the towbar is en-
trusted to a CITROËN dealer or
a qualifi ed workshop.
If the trailer is not fi tted by a
CITROËN dealer, it is imperative
that it is fi tted using the vehicle's
electrical pre-equipment, in ac-
cordance with the manufacturer's
instructions. The rear parking sensors will
be deactivated automatically if
a genuine CITROËN towbar is
used.

Towbar suitable for the attachment of a
trailer or caravan with additional lighting
and signalling.
Your vehicle is primarily designed for
transporting people and luggage, but it
may also be used for towing a trailer. Driving with a trailer places greater de-
mands on the towing vehicle and the
driver must take particular care.


Driving advice


Distribution of loads


)
Distribute the load in the trailer so
that the heaviest items are as close
as possible to the axle and the nose
weight approaches the maximum
permitted without exceeding it.
Air density decreases with altitude, thus
reducing engine performance. Above
1 000 metres, the maximum towed load
must be reduced by 10 % for every
1 000 metres of altitude.
Refer to the "Technical Data" section for
details of the weights and towed loads
which apply to your vehicle.

Side wind


)
Take into account the increased
sensitivity to side wind.


Cooling
Towing a trailer on a slope increases
the temperature of the coolant.
As the fan is electrically controlled, its
cooling capacity is not dependent on
the engine speed.


)
To lower the engine speed, reduce
your speed. The maximum towed load on a long in-
cline depends on the gradient and the
ambient temperature.
In all cases, keep a check on the coolant
temperature.


)
If the warning lamp and the
STOP
warning lamp come
on, stop the vehicle and
switch off the engine as
soon as possible.


Braking
Towing a trailer increases the braking
distance.

Tyres


)
Check the tyre pressures of the towing
vehicle and of the trailer, observing the
recommended pressures.


Lighting


)
Check the electrical lighting and sig-
nalling on the trailer.

TECHNICAL DATA

The GTW and towed load values indicated are valid up to a maximum altitude of 1 000 metres; the towed load mentioned
must be reduced by 10 % for each additional 1 000 metres of altitude.
The speed of a towing vehicle must not exceed 60 mph (100 km/h) (comply with the legislation in force in your country).
High ambient temperatures may result in a reduction in the performance of the vehicle to protect the engine; if the ambient
temperature is above 37 °C, limit the towed load.
*
The weight of the braked trailer can be increased, within the GTW limit, if the GVW of the towing vehicle is reduced by an
equal amount. Warning: towing using a lightly loaded towing vehicle may have an adverse effect on its road holding.
