TRAJECTORY CONTROL SYSTEMS

Anti-slip regulation (ASR) and electronic stability programme(ESP)


The anti-slip regulation (also known as
Traction Control) optimises traction to
prevent skidding of the wheels, by act-
ing on the brakes of the driving wheels
and on the engine.
The electronic stability programme 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)

Your vehicle has a system to help driving
on snow: Intelligent Traction Control.
This automatic system continuously
checks for 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, Intelligent Traction
Control
takes over from the ASR
sys-
tem, limiting the amount of wheel slip to
provide the best traction and trajectory
control, even without snow tyres and
with or without chains.
In extremely severe conditions (snow
on top of ice, sand, deep mud…), it can
be useful to deactivate the ESP/ASR

systems to allow a degree of wheel spin
and so recover grip.

Deactivation
In exceptional conditions (starting a ve-
hicle which is bogged down, stuck in
snow, on soft ground...), it may be ad-
visable to deactivate the ASR and ESP
systems, so that the wheels can move
freely and regain grip.


)
Press the "ESP OFF"
button, located
on the left below the steering wheel.

If this warning lamp comes on
in the instrument panel and
the indicator lamp in the button
comes on, this indicates that
the ASR and ESP systems are
deactivated.

ELECTRIC PARKING BRAKE

The electric parking brake combines
2 operating 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 ve-
hicle, the automatic application when the
engine is switched off and the automatic
release when you press the accelerator
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 parking
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:


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

- display of the message
"Handbrake on".

Before leaving the vehicle, check
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 loud beep is heard
and a message is displayed if the park-
ing brake has not been applied, unless
the gear lever is in position P
(Park) in
the case of an automatic gearbox.
Activation/deactivation is per-
formed using the vehicle confi gu-
ration menu, refer to the section
on parameter settings for the
systems of your vehicle.

The parking brake is then applied and
released manually. When the driver's
door is opened, there is an audible signal
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.

Manual release

With the ignition on or the engine run-
ning, to release the parking brake,
press
on the brake

pedal
or the accel-
erator, pull then release
control A
.
The full application of the parking brake
is confi rmed by:


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

- display of the message
"Handbrake off".

If you pull control lever A
with-
out pressing the brake pedal,
the parking brake will not be
released and a warning lamp
will come on in the instrument
panel.


Maximum application

If necessary, you can utilise maximum
application
of the parking brake. It is
obtained by means of a long pull
on
the control lever A
, until you see the
message "Handbrake on maximum"
and a beep is heard.

Maximum application is essential:



- in the case of a vehicle towing a
caravan or a trailer, if the auto-
matic functions are activated but
you are applying the parking brake
manually,

- when the gradient you are parked
on may vary (e.g. on a ferry, on a
lorry, during towing),

In the case of towing, a loaded vehicle
or parking on a gradient, make a maxi-
mum application of the parking brake
then turn the front wheels towards the
pavement and engage a gear when you
park.
After a maximum application, the re-
lease time will be longer.

Automatic application, engine off

With the vehicle stationary, the parking
brake is automatically applied when
the engine is switched off.

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
"Handbrake on".

Before leaving the vehicle, check
that parking brake warning lamp
in the instrument panel is on
fi xed (not fl ashing).
Never leave a child alone inside
the vehicle with the ignition on,
as they could release the parking
brake.

In the case of towing, a loaded
vehicle or parking on a gradient,
turn the front wheels towards the
pavement and engage a gear
when you park.

When stationary, with the engine
running, do not press the ac-
celerator pedal unnecessarily,
as you may release the parking
brake.



Immobilising the vehicle,
engine running
With the engine running and the vehicle
stationary, in order to immobilise the
vehicle it is essential to manually
ap-
ply the parking brake by pulling
control
lever A
.
The application of the parking brake is
confi rmed by:


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

Before leaving the vehicle, check
that parking brake warning lamp
on the instrument panel is on
fi xed, not fl ashing.

Particular situations


In certain situations (e.g. starting the
engine), the parking brake can auto-
matically alter its force. This is normal
operation.
To advance your vehicle a few centime-
tres without starting the engine, but with
the ignition on, press on the brake pedal
and release the parking brake by pull-
ing
then releasing
the control lever A
.
The full release of the parking brake is
confi rmed by the warning lamps in the
control lever A
and in the instrument
panel going off and display of the mes-
sage "Handbrake off".
If the parking brake malfunctions while
applied
or if the battery runs fl at, an
emergency release is always possible.

On sharp acceleration, the gear-
box will not change up unless the
driver acts on the gear lever or
the steering mounted paddles.
Never select neutral N
while the
vehicle is moving.
Only engage reverse gear R

when the vehicle is immobilised
with the brake pedal pressed.



Manual gear changing

This selective gear change mode en-
ables you to overtake, for example, while
still remaining in automatic mode.


)
Operate the +
or -
steering mounted
control paddle.
The gearbox engages the gear requested
if the engine speed permits. AUTO
is
still displayed in the instrument panel.
After a few moments without any action
on the controls, the gearbox resumes
automatic control of the gears.
At very low speed, if reverse
gear is requested, this will only
be taken into account when the
vehicle is immobilised. The Foot
on brake
warning lamp may
fl ash in the instrument panel to
prompt you to brake.


Stopping the vehicle

Before switching off the engine, you
can choose to:


- move to position N
to engage neutral,

- leave the gear engaged; in this
case, it will not be possible to move
the vehicle.
In both cases, you must apply the park-
ing brake to immobilise the vehicle.
When immobilising the vehicle,
with the engine running, you
must place the gear lever in
neutral N
.
Before carrying out any work in
the engine compartment, check
that the gear lever is in neutral N

and that the parking brake is
applied.

Operating fault

With the ignition on, the fl ashing of
AUTO
, accompanied by an audible sig-
nal and a message in the multifunction
screen, indicates a malfunction of the
gearbox.
Have it checked by a CITROËN dealer
or a qualifi ed workshop.

You must press the brake pedal
when starting the engine.
Whatever the circumstances,
you must manually apply the
parking brake when parking,
unless the parking brake is pro-
grammed in automatic mode.



Manual mode



)
When the vehicle has moved off, se-
lect position M
to change to manual
mode.

AUTO
disappears and the
gears engaged appear in suc-
cession in the instrument panel
screen.
The gear change requests are only car-
ried out if the engine speed permits.
It is not necessary to release the accel-
erator during gear changes.
When braking or slowing down, the
gearbox changes down automatically
to allow the vehicle to accelerate in the
correct gear.

for sequential

changing of the six gears.

)
Push the lever towards the +
sign to
change up a gear.

)
Pull the lever towards the -
sign to
change down a gear.
It is only possible to change from one
gear to another if the vehicle speed
and engine speed permit; otherwise,
the gearbox will operate temporarily in
automatic mode.

D
disappears and the gears
engaged appear in succes-
sion in the instrument panel.
If the engine speed is too low
or too high, the gear selected
fl ashes for a few seconds, then the ac-
tual gear engaged is displayed.
It is possible to change from position D

(automatic) to position M
(manual) at
any time.
When the vehicle is stationary or moving
very slowly, the gearbox selects gear M1

automatically.
The sport and snow programmes do
not operate in manual mode.
Invalid value during manual
operation
This symbol is displayed if a
gear is not engaged correctly
(selector between two posi-
tions).



Stopping the vehicle

Before switching off the engine, you
can engage position P
or N
to place the
gearbox in neutral.
In both cases, apply the parking brake
to immobilise the vehicle, unless it is
programmed to automatic mode.

If the lever is not in position P
,
when the driver's door is opened
or approximately 45 seconds af-
ter the ignition is switched off,
there is an audible signal and a
message appears.


)
Return the lever to position P
;
the audible signal stops and
the message disappears.


You risk damaging the gearbox:


- if you press the accelerator
and brake pedals at the same
time,

- if you force the lever from po-
sition P
to another position
when the battery is fl at. When the ignition is on, the
lighting of this warning lamp,
accompanied by an audible
signal and a message in the multifunction
screen, indicates a gearbox malfunction.
In this case, the gearbox switches to
back-up mode and is locked in 3rd gear.
You may feel a substantial knock when
changing from P
to R
and from N
to R
.
This will not cause any damage to the
gearbox.
Do not exceed 60 mph (100 km/h), local
speed restrictions permitting.
Have it checked by a CITROËN dealer
or a qualifi ed workshop.
This warning lamp may also come on if
a door is opened.
Operating fault
To reduce fuel consumption
when stationary for long periods
with the engine running (traffi c
jam...), position the gear lever at
N
and apply the parking brake,
unless it is programmed in auto-
matic mode.

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:



- provided you are in fi rst gear or neu-
tral with a manual gearbox,

- provided you are in position A
or M

with the electronic gearbox system,

- provided 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 assist
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 vehicle
stationary and reverse gear engaged,
the vehicle is held for a brief moment
when you release the brake pedal.

Operating fault

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

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.
