PANORAMIC SUNROOF
Your vehicle is fi tted with a tinted glass
panoramic sunroof which increases the
light and visibility in the passenger com-
partment. Its electric blind helps control
the temperature in the passenger com-
partment.

Electric blind


Opening
Turn the dial to the left (four possible
settings).

Closing
Return the dial to the initial position.
Safety anti-pinch
If the blind encounters an obstacle dur-
ing closing, it stops and partially opens
again.
If the blind fails to close at a second
attempt, it may be necessary to force
the closing of the blind using the reini-
tialisation procedure.
The blind is controlled electrically by a
rotary dial.
In the event of contact during op-
eration of the blind, you must re-
verse its movement. To do this,
turn the dial.
When the driver operates the
dial, they must ensure that noth-
ing prevents the blind from closing
correctly.
The driver must ensure that the
passengers use the blind cor-
rectly.
Be aware of children during op-
eration of the blind.

Reinitialising the system


Following reconnection of the battery,
or in the event of a malfunction in its
operation, it may be necessary to reini-
tialise the system:


)
turn the dial to the fully closed
position,

)
then immediately press the dial, clos-
ing starts after about 10 seconds,

)
maintain pressure on the dial until
the blind has fully closed.

The anti-pinch function is inoperative
during these operations.

If the position of the blind does not
agree with the position indicated by the
dial, press the dial to open the blind to
this position.

Switching off the lighting when
switching off the ignition
When the ignition is switched off,
all of the lamps switch off immedi-
ately, except for the dipped beam
headlamps if automatic guide-
me-home lighting is activated.
In some weather conditions (e.g.
low temperature or humidity),
the presence of misting on the
internal surface of the glass of
the headlamps and rear lamps
is normal; it disappears after the
lamps have been on for a few
minutes.






Daytime running lamps

Daytime lighting, compulsory in certain
countries, which comes on automati-
cally when the engine is started making
the vehicle more visible to other users.
Manual guide-me-home lighting
Temporarily keeping the dipped beam
headlamps on after the vehicle's igni-
tion has been switched off makes the
driver's exit easier when the light is poor.

Switching on


)
With the ignition off, "fl ash" the
headlamps using the lighting stalk.

)
A further "headlamp fl ash" switches
the function off.


Switching off

The manual guide-me-home lighting
switches off automatically after a set time.



This function is assured:


- in countries where it is imposed by
regulations,
by illumination of the dipped beam
headlamps with the sidelamps and
number plate lamps; this function
cannot be deactivated.

- for other countries where it is pro-
vided,
by the use of dedicated lamps; this
function can be activated or deac-
tivated via the vehicle confi guration
menu.


The instruments and controls (instru-
ment panel, multifunction screen, air
conditioning control panel, ...) are not
illuminated, except in night mode with
manual or automatic illumination of
headlamps.

Switching on the lighting
when switching on the ignition
To reactivate the lighting control stalk, turn the ring A
to position "0"
- lighting off, then to the position of
your choice.
If the lighting is switched on manu-
ally after switching off the ignition,
there is an audible signal when a
front door is opened to warn the
driver that they have forgotten to
switch off the vehicle's lighting, with
the ignition off.
They switch off automatically after a
period which depends on the state
of charge of the battery (entry to en-
ergy economy mode).

STOP & START
The Stop & Start system puts the en-
gine temporarily on standby - STOP
mode - during stops in the traffi c (red
lights, traffi c jams, or other...). The en-
gine restarts automatically - START
mode - as soon as you want to move
off. The restart takes place instantly,
quickly and silently.
Perfect for urban use, the Stop & Start
system reduces fuel consumption and
exhaust emissions as well as the noise
level when stationary.

Operation


Going into engine STOP mode
The "ECO"
warning lamp comes
on in the instrument panel and the
engine goes into standby:


- with a manual gearbox
, at speeds
below 12 mph (20 km/h), when you
put the gear lever into neutral and
release the clutch pedal, If your vehicle is fi tted with
the system, a time counter
calculates the sum of the pe-
riods in STOP mode during a
journey. It resets itself to zero every time
the ignition is switched on with the key.

- with the 6-speed electronic gear-
box system
, at a speed below
5 mph (8 km/h), when you press the
brake pedal or put the gear lever
into position N
. With the automatic gearbox
system, for your comfort dur-
ing parking maoeuvres, STOP
mode is not available for a few
seconds after coming out of re-
verse gear.
STOP mode does not affect the
functionality of the vehicle, such
as braking, power steering, for
example.
Special cases: STOP mode
unavailable
STOP mode is not invoked when:


- the driver's door is open,

- the driver's seat belt is not fastened,

- the vehicle has not exceeded 6 mph
(10 km/h) since the last engine start
using the key,

- the electric parking brake is applied
or being applied,

- the engine is needed to maintain a
comfortable temperature in the pas-
senger compartment,

- demisting is active,

- 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 a few seconds,
then goes off. Never refuel with the engine in
STOP mode; you must switch off
the ignition with the key.

This operation is perfectly normal.

- 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-

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.

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.
