If the temperature is below -23°C, the
engine should be left at idle for four
minutes, to ensure the correct operation
and durability of the engine and gearbox.
When you move the selector to select a
position, the corresponding indicator is
displayed in the instrument panel.
When the engine is running at idle, with
the brakes released, if position R
, D or

without the accelerator being pressed.
Do not leave children unsuper vised inside
the vehicle when the engine is running.
When carrying out maintenance with the
engine running, apply the parking brake
and select position P .
Automatic operation
F Select position D for automatic changing of
the six gears.
The gearbox then operates in auto-adaptive
mode, without any action needed from the
driver. It continuously selects the most suitable
gear according to the style of driving, the profile
of the road and the load in the vehicle.
For maximum acceleration without touching
the selector, press the accelerator 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 efficient engine
braking.
Driving

Gears are changed only if the vehicle’s
speed and engine speed allow; other wise, the
gearbox will operate temporarily in automatic
mode. It is possible to change from position D
(automatic) to position M (manual) at any time.
When the vehicle is stationary or crawling, the
gearbox engages first gear automatically.
The sport and snow programmes are inactive
in manual mode.
Invalid value during manual
operation
This symbol is displayed if a gear
is not engaged correctly (selector
between two positions).
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.
D disappears, and the gears engaged appear
in succession on the instrument panel.
If the engine is under-revving or over-revving,
the gear selected flashes for a few seconds,
then the actual gear engaged is displayed.
If the selector is not in position P
, when the
driver's door is opened or approximately
45 seconds after the ignition is switched
off, a warning message appears in the
screen.

Malfunction
When the ignition is on, the lighting
of this warning lamp, accompanied
by an audible signal and a message
in the screen, indicates a gearbox
fault.
In this case, the gearbox switches to back-up
mode and is locked in 3
rd 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.
Contact a CITROËN dealer or a qualified
workshop as soon as possible.
There is a risk of damage to the gearbox:
-

i

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

i

f you force the movement of the
selector from position P to another
position when the battery is flat.
To reduce fuel consumption when at
a prolonged standstill with the engine
running (traffic jam, etc.), put the
selector in position N and apply the
parking brake. If your vehicle has an automatic gearbox,
never try to start the engine by pushing
the vehicle.
Gear efficiency indicator
System which 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 shift recommendations should not be
considered obligatory. The configuration of the
road, the amount of traffic and safety remain
determining factors when choosing the best
gear. The driver thus remains responsible
for deciding whether to follow or ignore the
system's instructions.
This function cannot be deactivated.
With an automatic gearbox, the system is
only active in manual mode. On BlueHDi Diesel versions with manual
gearbox, in certain driving conditions the
system may suggest changing into neutral so
that the engine can go into standby (STOP
mode of Stop & Start). In this case, N is
displayed in the instrument panel.
Example:
-

Y
ou are in 3
rd g e a r.
-
Y
ou press the accelerator pedal.
-

T

he system may suggest that you engage a
higher gear.
The system adapts its gear change
recommendations according to the
driving conditions (slope, load, etc.)
and the demands of the driver (power,
acceleration, braking, etc.).
The system never suggests:
-
e

ngaging first gear,
-
enga

ging reverse gear,
-
enga

ging a lower gear.
The information appears in the instrument
panel in the form of an arrow.
Driving

129
On vehicles fitted with a manual gearbox,
the arrow may be accompanied by the
gear recommended.
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.
It is only active 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.Do not leave the vehicle while it is being
held temporarily in the hill start assist
phase.
If you need to leave the vehicle with the
engine running, apply the parking brake
manually then ensure that the parking
brake warning lamp lights up fixed on the
instrument panel. The hill start assist function cannot be
deactivated. However, use of the parking
brake to immobilise the vehicle interrupts
its operation.
On an ascending slope, with the vehicle
stationar y, the vehicle is held for a shor t
time when you release the brake pedal:
With a manual gearbox, if you are in first gear
or in neutral.
With an automatic gearbox, if you are in
position D or M . On a descending slope, with the vehicle
stationary and reverse gear engaged, the
vehicle is held for a shor t time when you
release the brake pedal.
Malfunction
If a fault in the system occurs, this warning
lamp comes on accompanied by a message.
Contact a CITROËN dealer or a qualified
workshop to have the system checked.
Stop & Start
The Stop & Start system puts the engine
t emporarily into standby – STOP mode – during
stops in traffic (red lights, traffic jams, etc.). The
engine restarts automatically – START mode –
as soon as you want to move off.
The restart takes place instantly, quickly and
silently.
Per fect for urban use, the Stop & Start system
reduces fuel consumption and exhaust
emissions as well as the noise level when
stationary.

Stop & Star t time counter
(minutes/seconds or hours/minutes)
For your comfort, during parking
manoeuvres, STOP mode is not available
for a few seconds after coming out of
reverse gear.
The Stop & Start system does not affect
the functionality of the vehicle, 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.
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.

the blade and its correct operation.
In certain extreme weather conditions
(rain and/or snow, bright sunshine, etc.)
the head-up display may not be legible or
may suffer temporary interference.
Some sunglasses may hamper reading of
the information.
To clean the blade, use a clean, soft cloth
(such as a spectacles cloth or microfibre
cloth). Do not use a dry or abrasive cloth
or detergent or solvent products as these
could scratch the blade or damage the
anti-reflection coating.
This system operates when the engine is
running, and the settings are stored when
the ignition is switched off.
Memorising speeds
This function allows speed settings to be stored
that will then be offered for configuration of two
systems: speed limiter or cruise control.
You can store up to six speed settings for each
system.
Default speed settings have already been
stored.As a safety measure, the driver must only
carry out these operations to change

The system is activated from 3 mph (5 km/h).
I t takes account of:
-

v
ehicles driving in the same direction or
stationary,
-

p
edestrians in the traffic lane (bicycles,
motorcycles, animals and objects on the
road are not necessarily detected).
This system is designed to assist the
driver and improve road safety.
It is the driver's responsibility to
continuously monitor the state of the
traffic, observing the driving regulations.
This system does not replace the need for
vigilance on the part of the driver.
As soon as the system detects a potential
obstacle, it prepares the braking circuit in
case automatic braking is needed. This
may cause a slight noise and a sense of
deceleration.
Operating limits
In the following cases, deactivating the
system via the vehicle's configuration menu is
recommended:
-
w
hen towing a trailer,
-

w
hen carrying long objects on roof bars or a
roof rack,
-

b
efore using an automatic car wash, with
the engine running,
-

b
efore placing the vehicle on a rolling stand
in a workshop,
-

w
hen the vehicle is being towed, with the
engine running,
-

w
hen a "space-saver" type spare wheel is
fitted (depending on version),
-
fo

llowing impact damage to the windscreen
close to the detection camera,
-

i
f the brake lamps are not working.It is possible that warnings are not given,
are given too late or seem unjustified.
Consequently, always stay alert and be
prepared to react at any time to avoid an
accident.
Collision Risk Alert
Depending on the degree of risk of collision
detected by the system and the alert threshold
chosen by the driver, different levels of
alert can be triggered and displayed in the
instrument panel or on the head-up display. Level 1 (orange) : visual alert only,
signalling to you that the vehicle in
front is very close.
The message " Vehicle close" is
displayed.
This level of alert is based on the inter-vehicle
time between your vehicle and the vehicle in
front. Level 2 (red) : visual and audible
alert, warning you that a collision is
imminent.
The message " Brake!" is displayed.
This level of alert is based on the time before
collision. It takes into account the vehicle
dynamics, the speed of your vehicle and the
one in front, the environmental conditions, the
operating conditions of the vehicle (on a cur ve,
pedals pressed, etc.) to trigger the alert at the
relevant moment.
