SAFETY
146
For the airbags to be fully
effective, observe the
following safety rules:
Sit in a normal upright position.
Wear a correctly adjusted seat
belt.
Do not leave anything between
the occupants and the airbags
(a child, pet, object...). This could
hamper the operation of the air-
bags or injure the occupants.
After an accident or if the ve-
hicle has been stolen or broken
into, have the airbag systems
checked.
All work on the airbag system must
be carried out by a CITROËN
dealer or a qualifi ed workshop.
Even if all of the precautions men-
tioned are observed, a risk of in-
jury or of minor burns to the head,
chest or arms when an airbag is
deployed cannot be ruled out.
The bag infl ates almost instantly
(within a few milliseconds) then
defl ates within the same time dis-
charging the hot gas via openings
provided for this purpose.
Front airbags
Do not drive holding the steering wheel by its spokes or resting your hands on
the centre part of the wheel.
Passengers must not place their feet on the dashboard.
If possible, do not smoke as deployment of the airbags can cause burns or the
risk of injury from a cigarette or pipe.
Never remove or pierce the steering wheel or hit it violently.
Lateral airbags
Use only approved covers on the seats, compatible with the deployment the lateral
airbags. For information on the range of seat covers suitable for your vehicle, you
can contact a CITROËN dealer (see "Practical information - § Accessories").
Do not fi x or attach anything to the seat backs (clothing...). This could cause in-
jury to the chest or arms if the lateral airbag is deployed.
Do not sit with the upper part of the body any nearer to the door than necessary.
Curtain airbags
Do not fi x or attach anything to the roof. This could cause injury to the head if the
curtain airbag is deployed.
If fi tted on your vehicle, do not remove the grab handles installed on the roof, they
play a part in securing the curtain airbags.

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:
- the braking warning lamp
and the P
warning lamp in
the control lever A
going off,
- 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 make a maxi-
mum application
of the parking brake.
This is obtained by means of a long
pull
on the control lever A
, until you
see the message "Handbrake on maxi-
mum" and a beep is heard.
Maximum application is essential:
- in the case of a vehicle towing a
caravan or a trailer, if the automatic
functions are activated but you are
applying the parking brake manu-
ally,
- 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, en-
sure 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 park-
ing 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
,
- display of the message
"Handbrake on".
Before leaving the vehicle, en-
sure that parking brake warning
lamp in 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 pulling
then releasing
the control lever A
. The
full release of the parking brake is con-
fi rmed by the warning lamps in the con-
trol lever A
and in the instrument panel
going off and display of the message
"Handbrake off".
If the parking brake develops a fault
while applied
or if the battery runs fl at,
an emergency release is always pos-
sible.
When the driver’s door is opened, a
message is displayed accompanied by
an audible signal, if the parking brake
has not been applied, except in the
case of an automatic gearbox with the
gear lever in position P
.

Immobilise the vehicle by placing
the blocks in front or behind the two
front wheels, opposite to the direc-
tion of the slope.
For safety reasons, after this op-
eration it is essential to contact
a CITROËN dealer or a qualifi ed
workshop without delay to re-
place the protective cover.
Following an emergency unlock-
ing, immobilisation of the vehicle
is no longer assured once the
manual emergency release has
been deployed and the manual
control does not allow the re-ap-
plication of your parking brake.
Take no action, either on the
control lever A
, or stopping start-
ing the engine while the release
device is engaged.
Take care not to allow moisture
or dust in the proximity of the
protective cover.
)
Remove the storage box under the
boot carpet for access to the emer-
gency release device.
)
Pierce the protective cover D
on the
tube E
with the release device.
)

For safety reasons
, it is essential
to continue turning the device until it
reaches its stop. The parking brake
is released.
)
Remove the release device and
store it with the blocks in the toolbox
under the boot carpet.
- The operation of the parking
brake reinitialises when the igni-
tion is switched off then on again.
If the reinitialisation of the parking
brake proves impossible, contact
a CITROËN dealer or a qualifi ed
workshop.

You can change mode at any
time by moving the gear lever
from A
to M
or the other way
round.
At very low speed, if reverse gear is re-
quested, this will only be acted on when
the vehicle is immobilised. The Foot on
brake
warning lamp may come on in
the instrument panel to prompt you to
brake.
At high speed, if reverse gear is re-
quested, the N
indicator fl ashes and the
gearbox goes into neutral. To engage a
gear again, put the gear lever in posi-
tion A
or M
.
When immobilising the vehicle,
with the engine running, you
must place the gear lever in neu-
tral N
.
Before carrying out any work in
the engine compartment, ensure
that the gear lever is in neutral N
and that the parking brake is ap-
plied.
Whatever the circumstances,
you must manually apply the
parking brake when parking,
unless the parking brake is pro-
grammed in automatic mode.
Reverse
To engage reverse gear R
, the vehicle
must be immobilised with your foot on
the brake pedal.
)
Select position R
.
Operating fault
With the ignition on, the fl ashing of
AUTO
, accompanied by an audible sig-
nal and a message in the screen, indi-
cates a malfunction of the gearbox.
Have it checked by a CITROËN dealer
or a qualifi ed workshop.
Manual mode
)
Select position M
.
The gears engaged appear in
succession in the instrument
panel screen.
The gear change requests are only act-
ed on 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.
On sharp acceleration, the gearbox will
not change up unless the driver acts on
the gear lever or the steering mounted
paddles.
Temporary control of gear changing
You can temporarily take over control
of gear changing using the "+"
and "-"
steering mounted paddles: if the engine
speed allows, the request to change
gear is acted on.
This function allows you to anticipate
certain situations such as overtaking a
vehicle or the approach to a corner.
After a few moments without any action
on the control paddles, the gearbox re-
sumes automatic control of the gears.
Never select neutral N
while the
vehicle is moving.
In both cases, you must apply the
parking brake
to immobilise the
vehicle. When immobilising the vehicle,
with the engine running, you must place
the gear lever in neutral
Stopping the vehicle
Before switching off the engine, you
can:
- move to position N
to engage neutral,
or
- leave the gear engaged; in this
case, it will not be possible to move
the vehicle.

idle, with the brakes released,
if position R
, D
or M
is selected,
the vehicle moves even without
the accelerator being pressed.
When the engine is running,
never leave children in the ve-
hicle without supervision.
When carrying out maintenance
with the engine running, apply
the parking brake and select po-
sition P
.
Automatic operation
)
Select position D
for automatic
changing of the six gears.
The gearbox then operates in auto-
adaptive mode, without any intervention
on the part of the driver. It continuously
selects the most suitable gear accord-
ing to the style of driving, the profi le of
the road and the load in the vehicle.
For maximum acceleration without
touching the lever, press the accelera-
tor pedal down fully (kick down). The
gearbox changes down automatically
or maintains the gear selected until the
maximum engine speed is reached.
On braking, the gearbox changes down
automatically to provide effi cient engine
braking.
If you release the accelerator sharply,
the gearbox will not change to a higher
gear for safety reasons.
Never select position N
while the
vehicle is moving.

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 mov-
ing 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 accelera-
tor 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 multifunc-
tion screen, indicates a gearbox mal-
function.
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), lo-
cal 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:
- 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 engine 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
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 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.
