HILL START ASSIST

System which keeps your vehicle im-
mobilised temporarily (approximately
2 seconds) when starting on a gradi-
ent, the time it takes to move your foot
from the brake pedal to the accelerator
pedal.
This function is only active when:


- the vehicle is completely stationary,
with your foot on the brake pedal,

- when certain conditions of gradient
are met,

- with the driver’s door closed.
The hill start assist function cannot be
deactivated.

On an ascending slope, with the ve-
hicle stationary, the vehicle is held
for a brief moment when you release
the brake pedal:



- if you are in fi rst gear or neutral with
a manual gearbox,

- if you are in position A
or M
with the
electronic gearbox system.

- if you are in position D
or M
with an
automatic gearbox.


Operation


Do not leave the vehicle while it
is being held in the hill start as-
sist phase.
If you need to leave the vehicle
while the engine is running, apply
the parking brake manually then
ensure that the parking brake
warning lamp is on (not fl ashing)
in the instrument panel.

On a descending slope, with the ve-
hicle stationary and reverse gear en-
gaged, the vehicle is held for a brief
moment when you release the brake
pedal.




Operating fault

If a fault occurs with the system, these
warning lamps come on. Contact a
CITROËN dealer or a qualifi ed work-
shop to have the system checked.

STOP & START

The Stop & Start system puts the en-
gine temporarily into 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 en-
gine goes into standby automatically:


- 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
periods in STOP mode dur-
ing a journey. It resets itself to zero ev-
ery 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 electronic gearbox sys-
tem, for your comfort during park-
ing maoeuvres, STOP mode is
not available for a few seconds
after coming out of reverse 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 fas-
tened,

- 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.

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.

Maintenance

In the event of a malfunction with the
system, the "ECO OFF"
switch warn-
ing lamp fl ashes, then comes on con-
tinuously.
Have it checked by a CITROËN dealer
or a qualifi ed workshop.


Operating fault

Before doing anything under the
bonnet, 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 techno-
logy (reference numbers available from
a CITROËN dealer or a qualifi ed work-
shop).
Fitting a battery not listed by CITROËN
introduces the risk of malfunction 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.
In the event of a fault in STOP
mode, the vehicle may stall. All
of the instrument panel warning
lamps come on.
Depending on version, an alert
message may also be displayed
asking you to put the gear lever
into position N
and put your foot
on the brake pedal.
It is then necessary to switch off
the ignition, then restart the en-
gine using the key.

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 con-
stantly check the traffi c, to asses
the distances and relative speeds
of other vehicles and to predict
their movements before 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 detected
in front and behind are confused with
a lorry or a stationary object,

- when overtaking quickly.

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.

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.
