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.

Maintenance

In the event of a malfunction with the
system, the "ECO OFF"
switch warning
lamp fl ashes, then comes on continu-
ously.
have it checked by a CITROËN dealer
or a qualifi ed workshop.
In the event of a fault in STOP mode,
the vehicle may stall. It is then neces-
sary to switch off the ignition and start
the engine again using the key.


Operating fault

Before working under the bon-
net, deactivate the Stop & Start
system to avoid any risk of injury
resulting from automatic operation
of START mode.
This system requires a specifi c battery
with a special specifi cation and technol-
ogy (reference numbers available from
a CITROËN dealer or a qualifi ed work-
shop).
Fitting a battery not listed by
CITROËN introduces the risk of mal-
function of the system.
The Stop & Start system makes
use of advanced technology. All
work on this type of battery must
be done only by a CITROËN
dealer or a qualifi ed workshop.

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 malfunc-
tion, the service warning
lamp comes on, accompa-
nied by an audible signal
and a message in the screen.
Contact a CITROËN dealer or a qualifi ed
workshop.

BLIND SPOT SENSORS

This driving assistance system warns
the driver of the presence of another
vehicle in the blind spot angle of their
vehicle (areas masked from the driver's
fi eld of vision), as soon as this presents
a potential danger.
Operation



)
On switching on the ignition, or en-
gine running, press this button to
activate the function; the warning
lamp comes on.

This system is designed to im-
prove safety when driving and is
in no circumstances a substitute
for the use of the interior rear
view mirror and door mirrors. It
is the driver's responsibility to
constantly check the traffi c, to
asses the distances and relative
speeds of other vehicles and
to predict their movements be-
fore deciding whether to change
lane.
The blind spot sensor system
can never replace the vigilance
and responsibility of the driver.
Sensors fi tted in the front and rear bum-
pers monitor the blind spots. A warning lamp appears in the door
mirror on the side in question:


- immediately, when being overtaken,

- after a delay of about one second,
when overtaking a vehicle slowly.

DRIVING
163

No alert will be given in the following
situations:


- in the presence of stationary objects
(parked vehicles, barriers, street
lamps, road signs...),

- with vehicles moving in the opposite
direction,

- driving on a sinuous road or a sharp
corner, The alert is given by a warning lamp
which comes on in the door mirror on
the side in question as soon as a ve-
hicle - car, lorry, cycle - is detected and
the following conditions are fulfi lled:


- all the vehicles must be moving in
the same direction,

- the speed of your vehicle is between
7 and 75 mph (12 and 140 km/h),

- the difference in speed between
your vehicle and the other vehicles
must be less than 6 mph (10 km/h),

- the traffi c must be fl owing normally,

- in the case of an overtaking ma-
noeuvre, if this is prolonged and the
vehicle being overtaken remains in
the blind spot,

- you are driving on a straight or slightly
curved road,

- your vehicle is not pulling a trailer, a
caravan...

- when overtaking (or being over-
taken by) a very long vehicle (lorry,
coach...) which is at the same time
detected at the rear in the blind spot
angle and present in the driver's for-
ward fi eld of vision,

- in very heavy traffi c: vehicles detect-
ed in front and behind are confused
with a lorry or a stationary object,

- when overtaking quickly.

DRIVING
164

The system may suffer tem-
porary interference in certain
weather conditions(rain, hail...).
In particular, driving on a wet sur-
face or moving from a dry area to
a wet area can cause false alerts
(for example, the presence of a
fog of water droplets in the blind
spot angle is interpreted as a ve-
hicle).
In bad or wintry weather, ensure
that the sensors are not covered
by mud, ice or snow.
Take care not to cover the warn-
ing zone in the door mirrors or
the detection zones on the front
and rear bumpers with adhesive
labels or other objects; they may
hamper the correct operation of
the system.



)
To deactivate the system, press this
button again; the warning lamp goes
off.
The state of the system remains in
memory on switching off the ignition.

Operating fault

In the event of a fault, the warning lamp
in the button fl ashes then goes off.
Have it checked by a CITROËN dealer
or a qualifi ed workshop.
The system is automatically de-
activated when towing with a
towbar approved by CITROËN.

SPEED LIMITER

System which prevents the vehicle
from exceeding the speed programmed
by the driver.
When the programmed speed limit is
reached, pressing the accelerator pedal
no longer has any effect.
The speed limiter cannot, in any
circumstances, replace the need
to respect speed limits, nor can
it replace the need for vigilance
and responsibility on the part of
the driver. The functions of this system are grouped
together on the steering mounted con-
trols.

Steering mounted controls

Operation

The speed limiter is switched on
man-
ually: it requires a programmed speed
of at least 20 mph (30 km/h).
The speed limiter is switched off
by
manual operation of the control.
The programmed speed can be ex-
ceeded temporarily by pressing the
accelerator fi rmly beyond the point of
resistance.
To return to the programmed speed,
simply release the accelerator pedal.
The programmed speed remains in the
memory when the ignition is switched
off.
