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.

, when you
depress the clutch pedal,

- with the 6-speed electronic gearbox
system
:

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,

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 tech-
nology (reference numbers available
from a CITROËN dealer or a qualifi ed
workshop).
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.

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.

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

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
vehicle).
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.

PARKING SPACE SENSORS

System which measures the parking
space available between two vehicles
or obstacles. It measures the size of the
space and gives you information on:


- the possibility of fi tting into a free
space, depending on the dimensions
of your vehicle and the distances
needed for manoeuvring,

- the level of diffi culty of the manoeuvre
to be performed.
The system does not measure spaces
which are clearly much smaller or larger
than the size of the vehicle.

Displays in the instrument panel



- on fi xed:
the function is selected by
a press on control A
.

- off:
the function is not selected,
The parking space sensor
function warning lamp can
have two different states:
Operation
You have identifi ed a parking space:


)
Press button A
to select the function.

)
Operate the direction indicator on
the side where the space is to be
measured; a message is displayed
to confi rm that measurement is in
progress.

)
During measurement, go forward
the length of the space, at a speed
less than 12 mph (approx. 20 km/h),
to prepare for your manoeuvre.

)
Once the measurement has been
completed, the system informs you
of the level of diffi culty of the ma-
noeuvre by a message in the multi-
function screen accompanied by an
audible signal.
