TRAJECTORY CONTROL
SYSTEMS (ESP)

Anti-slip regulation (ASR) and
electronic stability control (ESC)

The anti-slip regulation (also known as
traction control) optimises traction to pre-
vent skidding of the wheels, by acting on
the brakes of the driving wheels and on
the engine.
The electronic stability control acts on
the brake of one or more wheels and
on the engine to keep the vehicle on the
trajectory required by the driver, within
the limits of the laws of physics.

Activation
These systems are activated automati-
cally each time the vehicle is started.
They come into operation in the event
of a grip or trajectory problem.
This is indicated by fl ashing of
this warning lamp in the instru-
ment panel.








Intelligent traction control
system ("Snow motion")
Your vehicle has a system to help driving
on snow: intelligent traction control.
This system detects situations of diffi -
cult surface adhesion that could make it
diffi cult to move off or make progress on
deep fresh snow or compacted snow.
In these situations, the intelligent trac-
tion control
limits the amount of wheel
slip to provide the best traction and tra-
jectory control for your vehicle.
In extremely severe conditions (deep
snow, mud, ...), when it proves impos-
sible to move off, it may be useful to
temporarily deactivate the ESP/ASR
systems to allow the wheels to spin
freely and so allow movement of the
vehicle.

Deactivation
In exceptional conditions (starting a
vehicle which is bogged down, stuck in
snow, on soft ground...), if you are un-
able to make progress, it may be ad-
visable to temporarily deactivate these
systems, so that the wheels can spin
freely and allow the vehicle to move.



Press the "ESP OFF"
button, locat-
ed near the steering wheel.
If the indicator lamp in the button comes
on, this indicates that these systems
are deactivated.
The use of snow tyres is strongly
recommended on surfaces of-
fering low levels of adhesion.

It is recommended that the systems be
reactivated as soon as possible.

Deactivation
Only the passenger's front airbag can
be deactivated:



insert the key in the passenger air-
bag deactivation switch,


turn it to the "OFF"
position,


then, remove the key keeping the
switch in the new position.
According to version, this warn-
ing lamp comes on in the in-
strument panel and/or in the
seat belt and passenger's front
airbag warning lamps display when the
ignition is on and until the airbag is re-
activated. To assure the safety of your
child, the passenger's front air-
bag must be deactivated when
you install a "rear facing" child
seat on the front passenger seat.
Otherwise, the child would risk
being seriously injured or killed if
the airbag were deployed.

Reactivation
When you remove the child seat, turn
the switch to the "ON"
position to re-
activate the airbag and so assure the
safety of your front passenger in the
event of an impact.
With the ignition on, this warn-
ing lamp comes on in the seat
belt and passenger's front air-
bag warning lamps display for
approximately one minute, if the pas-
senger's front airbag is activated.
Operating fault
If this warning lamp comes on
in the instrument panel, con-
tact a CITROËN dealer or a
qualifi ed workshop to have the
system checked. The airbags may no
longer be deployed in the event of a se-
rious impact.

ELECTRIC PARKING BRAKE


The electric parking brake combines
2 operational modes:


- Automatic Application/Release

Application is automatic when the
engine stops, release is automatic
on use of the accelerator (activated
by default),

- Manual Application/Release

The parking brake can be applied /
released manually by pulling control
lever A
.
If this warning lamp comes on
in the instrument panel, the au-
tomatic mode is deactivated.
Programming the mode
Depending on the country of sale of the
vehicle, the automatic application when
the engine is switched off and the auto-
matic release when you press the ac-
celerator can be deactivated.

It is recommended that you do
not apply the parking brake in
very cold conditions (ice) and
during towing (breakdown, cara-
van...). Deactivate the automatic
functions and release the park-
ing brake manually.



Manual application

With the vehicle stationary, to apply the
parking brake whether the engine is
running or off, pull
control lever A
.
The application of the parking brake is
confi rmed by:



- illumination of the braking warn-
ing lamp and of the P
warning
lamp in the control lever A
,


- display of the message
"Parking brake on".

Before leaving the vehicle, en-
sure that parking brake warning
lamp in the instrument panel is
on fi xed, not fl ashing.
When the driver’s door is opened with
the engine running, a message is dis-
played accompanied by an audible sig-
nal if the parking brake has not been
applied. Activation / deactivation is done
using the vehicle confi guration
menu; refer to the section cov-
ering the confi guration of your
vehicle's systems.
The parking brake is then applied and
released manually. When the driver's
door is opened, there is an audible sig-
nal and a message is displayed if the
brake is not applied.

Do not place any object (packet
of cigarettes, telephone...) be-
tween the gear lever and the
electric parking brake control
lever.

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.

GEAR SHIFT INDICATOR

System which reduces fuel consump-
tion by advising the driver to change up.
With an electronic gearbox, the system
is only active in manual mode.

Operation

Depending on the driving situation and
your vehicle's equipment, the system
may advise you to skip one (or more)
gear(s). You can follow this instruc-
tion without engaging the intermediate
gears.
The gear engagement recommenda-
tions must not be considered compulso-
ry. In fact, the confi guration of the road,
the amount of traffi c and safety remain
determining factors when choosing the
best gear. Therefore, the driver remains
responsible for deciding whether or not
to follow the advice given by the system.
This function cannot be deactivated.
- You press the accelerator pedal.
Example:


- You are in third gear.

- The system may suggest that you
engage a higher gear.
The information appears in the instru-
ment panel in the form of an arrow.
On vehicles with manual gearbox, the
arrow can be accompanied by the rec-
ommended gear.

The system adapts its gear
change recommendation ac-
cording to the driving conditions
(slope, load, ...) and the de-
mands of the driver (power, ac-
celeration, braking, ...).
The system never suggests:


- engaging fi rst gear,

- engaging reverse gear,

- engaging a lower gear.

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.
