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 an
electronic gearbox.
- 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 vehi-
cle while the engine is running,
apply the parking brake manu-
ally 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.

The fl ashing and then fi xed
illumination of the under-infl a-
tion warning lamp accompa-
nied by the illumination of the
"service" warning lamp indi-
cates a fault with the system.
Operating fault
The alert is given by the fi xed il-
lumination of this warning lamp,
accompanied by an audible sig-
nal, and depending on equip-
ment, the display of a message.
Under-inflation alert
The alert is maintained until the
tyre or tyres concerned is rein-
fl ated or repaired.
The loss of pressure detected
does not always lead to visible
deformation of the tyre. Do not
rely on just a visual check.
This alert is also displayed when
one or more wheels is not fi tted
with a sensor.
In the event of a problem on one of
the tyres, the symbol or the message
appears, according to equipment, to
identify it.
Reduce speed, avoid sudden steer-
ing movements or harsh brake ap-
plications.
Stop as soon as it is safe to do so.
In the event of a puncture, use the
temporary puncture repair kit or the
spare wheel (according to equip-
ment),
or
if you have a compressor, the one in
the temporary puncture repair kit for
example, check the four tyre pres-
sures when cold,
or
if it is not possible to check the tyre
pressures at the time, drive care-
fully at reduced speed. In this case, monitoring of the tyre pres-
sures is not assured.
Have the system checked by a
CITROËN dealer or a qualifi ed work-
shop.

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 coun-
ter calculates the sum of
the periods in STOP mode
d uring a journey. It resets itself to zero
every time the ignition is switched on
with the key.
- with an electronic gearbox
, at a
speed below 5 mph (8 km/h), when
you press the brake pedal or put the
gear lever into position N
. With an electronic gearbox, for
your comfort during parking
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 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"
warn-
ing lamp fl ashes for a few sec-
onds, 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 an electronic gearbox
:
●
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 an
electronic gearbox,
- 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 go-
ing off and the display of a message.
The system is reactivated auto-
matically at every new start us-
ing the key.
This operation is perfectly normal.

Maintenance
In the event of a malfunction with the sys-
tem, the "ECO OFF"
switch warning lamp
fl ashes, then comes on continuously.
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 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.
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.

The cruise control system can-
not, in any circumstances, re-
place the need to respect speed
limits, nor can it replace the need
for vigilance and responsibility
on the part of the driver.
You are advised to keep your
feet near the pedals at all times.

Displays in the instrument panel
Operation
The cruise control is switched on
manually: it requires a minimum ve-
hicle speed of 25 mph (40 km/h) and
engagement of:
- fourth gear on the manual gearbox,
- second gear on the electronic gear-
box system or automatic gearbox,
in sequential driving mode,
- position A
on the electronic gearbox
system or D
on an automatic gear-
box.
The cruise control is switched off
man-
ually or by pressing the brake or clutch
pedal or on triggering of the ESP sys-
tem for safety reasons.
It is possible to exceed the programmed
speed temporarily by pressing the ac-
celerator pedal.
To return to the programmed speed,
simply release the accelerator pedal.
Switching off the ignition cancels any
programmed speed value.
