control lever.
Repeat this procedure to reactivate automatic
operation.
Reactivation of automatic operation is
confirmed by the indicator lamp in the
instrument panel going off.
Emergency braking
The emergency braking should only be
used in an exceptional situation. In the event of a
failure of the main ser vice
brake or in an exceptional situation (e.g. driver
taken ill, under instruction, etc.), a continuous
pull on the control lever will brake the vehicle.
Braking takes place while the control lever is
being pulled. It is interrupted if the control lever
is released.
The ABS and DSC systems ensure stability of
the vehicle during emergency braking.
If the emergency braking malfunctions,
the message "Parking brake fault" will be
displayed.
If the ABS and DSC systems malfunction,
signalled by the illumination of one or both
warning lamps in the instrument panel, then
stability of the vehicle is no longer guaranteed.
In this event, stability must be assured by the
driver by repeating alternate "pull-release"
actions on the control lever until the vehicle is
immobilised.
Hill start assist
System which keeps your vehicle immobilised
temporarily (approximately 2 seconds) when
starting on a
gradient, the time it takes to
move your foot from the brake pedal to the
accelerator pedal. This system only operates when:
-

t
he vehicle is completely stationary, with
your foot on the brake pedal,
-
c
ertain slope conditions are met,
-
t
he driver's door is closed.
The hill start assist system cannot be
deactivated.
Do not leave the vehicle while it is being
held temporarily by hill start assist.
If you need to get out of the vehicle with
the engine running, apply the parking
brake manually. Then verify that the
parking brake warning lamp (and the
warning lamp P on the electric parking
brake control lever) are on continuously.

In the event of a
battery failure, you
must place the chocks supplied with the
vehicle tools against one of the wheels to
immobilise the vehicle.
If your vehicle has an automatic gearbox,
never try to start the engine by pushing
the vehicle.Automatic mode
F Select position D .
D and the gear engaged appear in the
instrument panel.
The gearbox operates in auto-adaptive mode,
without any action by the driver. It continuously
selects the gear best suited to the following
parameters:

ehicle load.
For maximum acceleration without touching
the selector, press the accelerator fully down
(kick-down). The gearbox changes down
automatically or holds the gear selected until
the maximum engine speed is reached.
When braking, the gearbox changes down
automatically to provide effective engine
braking.
If you release the accelerator sharply, the
gearbox will not change to a
higher gear for
safety reasons.
Temporary control of gear
changing
You can temporarily take control of gear
changes using the steering mounted control
paddles " +" and " -". The gear change
instruction is acted on if the engine speed
permits.
This function allows you to anticipate certain
situations, such as overtaking another vehicle
or approaching a
bend in the road.
After a
few moments with no action on the
control paddles, the gearbox returns to
automatic operation.
Manual mode
F Select position M .
F U se the steering mounted control paddles

The gears engaged are displayed in sequence
in the instrument panel.
When the vehicle is stationary or moving very
slowly, the gearbox automatically selects gear 1 .
Driving

139
In sequential mode, it is not necessary to
release the accelerator pedal when changing
g e a r.
Changing from one gear to another only
occurs if the vehicle speed and engine speed
conditions allow; other wise the gearbox will
operate temporarily in automatic mode.
If the engine speed is too low or too high, the
gear selected flashes for a few seconds, then
the gear actually engaged is displayed.
Invalid value during manual operation
This symbol is displayed if a gear
is not engaged correctly (selector
between two positions).
You can change mode at any time by
moving the gear selector from D to M or
vice versa.

eposition the lever to position P ; the
audible signal stops and the message
disappears.
Whatever the parking circumstances, you must
apply the parking brake manually to immobilise
the vehicle if automatic operation has been
deactivated.
In all circumstances, ensure that the
selector is in position P before leaving
your 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 In the event of a
battery failure, use the
chock to immobilise your vehicle.
Operating fault
If the gearbox malfunctions, the
Ser vice warning lamp comes on in
the instrument panel, accompanied
by a
message and an audible signal. Do not exceed 62
mph (100 km/h), local speed
restrictions permitting.
Have it checked by a CITROËN dealer or
a

qualified workshop.
In this case, the gearbox switches to back-up
mode and is locked in 3rd gear. You may then
feel a

substantial jolt when changing from P to
R and from N to R . This jolt will not cause any
damage to the gearbox.
Gear efficiency indicator
This system reduces fuel consumption by
recommending the most appropriate gear.
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 instruction without engaging the
intermediate gears.
Gear efficiency recommendations are for
information only. In fact, the road layout, the
traffic density and safety remain the deciding
factors when choosing the best gear. The driver
therefore remains responsible for deciding
whether or not to follow the indications issued
by the system.
This function cannot be deactivated.
With an automatic gearbox, the system is
only active in manual mode.

The information appears in the
instrument panel in the form of an
ar row.
With a
manual gearbox, the arrow may be
accompanied by the gear recommended.
This arrow may be pointing up or down,
depending on the context.
The system adapts its gear efficiency
recommendation according to the driving
conditions (slope, load, etc.) and the
driver's requirements (power, acceleration,
b r a k i n g , e t c .) .
The system never suggests:
-
e

ngaging first gear,
-
enga

ging reverse gear.
Stop & Start
Per fect for urban use, the Stop & Start system
reduces fuel consumption and exhaust
emissions as well as the noise level when
stationary.
The Stop & Start system puts the engine
temporarily into standby – STOP mode – during
stops in the traffic (red lights, traffic jams, or
other, etc.). The engine restarts automatically –
START mode – as soon as you wish to move off
again.
Restarting occurs instantaneously, quickly and
silently.

below 2
mph (3 km/h), or when the vehicle
is stationary (depending on version), when
you press the brake pedal or place the gear
selector into position N .
If your vehicle is fitted with this system, a time
counter calculates the sum of the periods in
STOP mode during a
journey. It resets to zero
every time the ignition is switched on with the
"START/STOP" button. For your convenience, during parking
manoeuvres, STOP mode is not available
for a
few seconds after coming out of
reverse gear.
The Stop & Start system does not modify
the vehicle's functions, such as, for
example, braking, power steering, etc.
Never refuel with the engine in STOP
mode; you must switch off the ignition with
the "START/STOP" button.
Special cases: STOP mode not
available
STOP mode is not invoked when:

Have it checked by a CITROËN dealer or
a qualified workshop.
If a
fault occurs in STOP mode, the engine may
stall.
All of the instrument panel warning lamps come
on.
Depending on version, an alert message may also
be displayed, asking you to place the gear lever in
position N and press the brake pedal.
It is then necessary to switch off the ignition and
start the engine again using the "START/STOP"
button.
The Stop & Start requires the use of
a 12 V battery of special specification and
technology.
All work on this type of battery must be
carried out only by a
CITROËN dealer or
a


qualified workshop.
For more information on the 12
V batter y,
refer to the corresponding section.
Opening the bonnet
Before doing anything under the bonnet,
deactivate the Stop & Start system to avoid
the risk of injury related to an automatic
change to START mode. Driving on flooded roads
Before driving in a
flooded area, it is
strongly recommended that you deactivate
the Stop & Start system.
For more information on Driving advice ,
particularly on flooded roads, refer to the
corresponding section.
Tyre under-inflation
detection
System which automatically checks the
pressures of the tyres while driving.
The system monitors the pressure of the four
tyres when the vehicle is moving.
It compares the information given by the
wheel speed sensors with reference values,
which must be reinitialised after ever y tyre
pressure adjustment or wheel change .
The system triggers an alert as soon as it
detects a
drop in the pressure of one or more
tyres. The under-inflation detection system does
not replace the need for vigilance on the
part of the driver.
This system does not avoid the need to
check the tyre pressures (including the
spare wheel) every month as well as
before a


long journey.
Driving with under-inflated tyres worsens
road-holding, lengthens braking distances,
causes premature wear of the tyres,
particularly in adverse conditions (heavy
loads, high speeds, long journeys).
Driving with under-inflated tyres
increases fuel consumption.
The inflation pressures defined for your
vehicle can be found on the tyre pressure
label.
For more information on the
Identification markings , refer to the
corresponding section.

Memorising speeds
This function allows speeds to be saved, which
can then be offered to set the two systems: the
speed limiter (to limit the speed of the vehicle)
or the cruise control (for a vehicle cruising
speed).
You can memorise up to six speed settings
for each of the two systems. By default, some
speed settings are already memorised.
Memorisation
This function can be accessed in the Driving
menu of the touch screen.

memorise new speed settings.
Speed Limit recognition
and recommendation
This system allows the speed limit detected by
the camera to be displayed in the instrument
panel.
The system also processes speed limit
information from the navigation system
mapping.
You should update your navigation
mapping regularly in order to receive
accurate speed limit information from the
system.
Specific speed limits, such as those for heavy
goods vehicles, are not displayed.
The display of the speed limit in the instrument
panel is updated as you pass a
speed limit sign
intended for cars (light vehicles).
Driving

145
The speed limit units (mph or km/h)
depend on the country you are driving in.
This should be taken into account in order
to obser ve the speed limit.
For the system to operate correctly when
you change country, the units for speed in
the instrument panel must be those for the
country you are driving in.
The automatic reading of road signs is
a driving assistance system and does not
always display speed limits correctly.
The speed limit signs present on the road
always take priority over the display by the
system.
The system cannot in any circumstances
replace the need for vigilance on the part
of the driver.
The driver must observe the driving
regulations and must adapt the speed of
the vehicle to suit the weather and traffic.
The system may not display the speed
limit if it does not detect a
speed limit sign
within a
preset period.
The system is designed to detect signs
that conform to the Vienna Convention on
road signs. To maintain correct operation of the
system: regularly clean the area in front of
the camera.
The internal sur face of the windscreen can
also become misted around the camera.
In humid and cold weather, demist the
windscreen regularly.
Activation/Deactivation
Activation and deactivation of the system is
done in the touch screen's Driving
menu.
Select the " Vehicle settings " tab, then

Speed limiter "LIMIT"
System which prevents the
vehicle from exceeding the speed
programmed by the driver.
Once the programmed speed limit is reached,
additional pressure on the accelerator pedal
has no effect.
Operation of the speed limiter requires
a

programmed speed of at least 19 mph
(30


km/h).
The speed limiter is paused using the control.
The programmed speed can be exceeded
temporarily by pressing the accelerator firmly
beyond the point of resistance.
To return to the programmed speed, simply
release the accelerator pedal until the set
speed limit has been reached again.
The programmed speed remains in the system
memory when the ignition is switched off.
The speed limiter cannot, in any circumstances,
replace the need to obser ve speed limits, nor can it
replace the need for vigilance on the part of the driver.
