Driving
Never leave the vehicle without first
switching the ignition off with the key.
Never refuel with the engine in STOP
mode; you must switch off the ignition
using the key.
Special cases: STOP mode
not available
STOP mode is not activated when:
– the system is initialising,
– the driver's door is open,
– the driver's seat belt is not fastened,
– the air conditioning is on,
– the rear screen demisting is on,
– the windscreen wipers are on fast wipe,
– the reverse gear is engaged for the parking
manoeuvre,
– some special conditions (battery charge,
engine temperature, particle filter regeneration,
braking assistance, exterior temperature, etc.)
where the engine is needed to assure control of
a system.
– during intensive use of Stop & Start, it may
be deactivated to conserve starting ability;
go to a CITROËN dealer to have the function
reactivated.
This indicator lamp in the instrument panel flashes for a few seconds, then
goes off.
This operation is perfectly normal.
Going into engine START
mode
With a gear engaged, the automatic restarting of
the engine is only possible by fully depressing
the clutch pedal.
This indicator lamp goes off and the engine restarts.
If, after an automatic restart in START mode, the
driver does not perform any action on the vehicle
within 3 minutes, the system stops the engine
permanently. The engine can only be restarted
with the ignition key.
Special cases: START mode
activated automatically
The START mode may be invoked automatically
in the following circumstances:
– the vehicle is free-wheeling on a gradient,
– the windscreen wipers are on fast wipe,
– the air conditioning is on,
– the engine has been stopped for around 3
minutes with Stop & Start,
– some special conditions (battery charge,
engine temperature, braking assistance, air
conditioning setting, etc.) where the engine is
needed for control of the system or vehicle.
In this case, a message appears in the
instrument panel screen, accompanied by
this indicator lamp, which flashes for a few
seconds, then goes off.
This operation is perfectly normal.
While in STOP mode with a manual
gearbox, if a gear is engaged without
fully depressing the clutch pedal, restarting
may not take place.
An indicator lamp and/or message is
displayed in the instrument panel asking
you to fully depress the clutch pedal to allow
restarting.
With the engine stopped in STOP mode,
if the driver unfastens their seat belt and
opens a front door, the engine can only be
restarted using the ignition key. There is an
audible signal, accompanied by flashing of this
indicator lamp, and the display of a message.
Malfunction
In the event of a malfunction, the Stop &
Start is deactivated and this warning lamp
comes on, accompanied by a message on the
instrument panel display.
Have the system checked by a CITROËN dealer
or a qualified workshop.
In the event of a malfunction in STOP mode, the
engine can be restarted by fully depressing the
clutch pedal or putting the gear lever in neutral.
Hill start assist
This system keeps your vehicle briefly stationary
(for approximately 2 seconds) when making a hill
start, while you transfer your foot from the brake
pedal to the accelerator pedal.
This system (also called HHC - Hill Hold
Control), integrated with the dynamic stability
control system, is activated in the following
conditions:
– the vehicle must be stationary, engine running,
foot on the brake,
– the gradient of the road must be steeper than
5%,
– uphill, the gearbox must be in neutral or in a
gear other than reverse,
– downhill, reverse gear must be engaged.
The hill start assist system is a driving
aid. It is not an automatic vehicle parking
function or an automatic parking brake.
Operation

With the brake pedal and clutch pedal pressed,
from the time you release the brake pedal,

Driving
6This system (also called HHC - Hill Hold
Control), integrated with the dynamic stability
control system, is activated in the following
conditions:
– the vehicle must be stationary, engine running,
foot on the brake,
– the gradient of the road must be steeper than
5%,
– uphill, the gearbox must be in neutral or in a
gear other than reverse,
– downhill, reverse gear must be engaged.
The hill start assist system is a driving
aid. It is not an automatic vehicle parking
function or an automatic parking brake.
Operation

With the brake pedal and clutch pedal pressed,
from the time you release the brake pedal,
without using the parking brake, you have
approximately 2 seconds to move off before the
vehicle starts to roll back.
During the moving off phase, the function is
deactivated automatically, gradually releasing
the braking pressure. During this phase, you
may hear the typical mechanical brake release
noise, signalling the imminent movement of the
vehicle.
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 ensure that the parking brake
indicator lamp is on.
Hill start assist is deactivated in the following
situations:
– when the clutch pedal is released,
– when the parking brake is applied,
– when the engine is switched off,
– if the engine stalls.
Malfunction
If a malfunction of the system occurs, this
warning lamp lights up, accompanied by
an audible signal and confirmed by a message
on the display. Have the system checked by a
CITROËN dealer or a qualified workshop.
Tyre under-inflation detection
System which automatically checks the
pressures of the tyres while driving.
The system continuously monitors the pressures
of the four tyres, as soon as the vehicle is
moving.
A pressure sensor is located in the valve of each
tyre (except the spare wheel).
The system triggers an alert as soon as it
detects a drop in the inflation 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
regularly check the tyre pressures (including
the spare wheel) as well as before a long
journey.
Driving with under-inflated tyres, particularly
in adverse conditions (heavy load, high
speed, long journey):
– worsens road-holding,
– lengthens braking distances,
– causes premature wear of the tyres,
– increases fuel consumption.

Driving
6Blind Spot Monitoring
System with trailer
detection
Refer to the General recommendations on the
use of driving and manoeuvring aids .


This system includes sensors, placed on the
sides of the rear bumper, which monitor the blind
spot areas.
It warns the driver of the presence of another
vehicle (car, truck, motorcycle) in the areas
hidden from their field of vision, while driving and
reversing.
If a trailer is hitched to the vehicle, the detection
area is enlarged by the length of the trailer.


The warning is given by a fixed warning lamp
that appears in the door mirror on the side in
question. Depending on the configuration, an
audible warning may sound.
Activation/Deactivation
The function can be activated or deactivated using the MODE button in the
Blind spot menu.
For more information on Vehicle configuration
(MODE), refer to the corresponding section.
Two modes of activation are available:
– VISUAL: visual warning. While driving, a
warning lamp appears in the door mirror on the
side where a vehicle is detected.
– VISUAL and AUDIBLE: visual and audible
warning. While driving, a warning lamp appears
in the door mirror on the side in question. If the
direction indicator is activated on the side where
the vehicle is detected, an audible warning will
sound.
When starting the vehicle, the warning lamp
comes on in each mirror to indicate that the
system is activated.
The status of the system remains in the memory
when the ignition is switched off.
Reverse gear

The system assists the driver during their
manoeuvres in reverse (e.g. exit from a parking
space).
It detects vehicles arriving to the left or right of
the vehicle at a speed of between approximately
1 and 22 mph (1 and 35 km/h).
When a vehicle is detected, a warning lamp
comes on in the mirror on the side in question,
supplemented by an audible warning.
Trailer detection
The system detects the presence and length of a
trailer. The vehicle detection area in blind spots
is extended by the length of the trailer.
The trailer detection mode is set via the MODE button.
For more information on Vehicle configuration
(MODE), refer to the corresponding section.
Two modes are available:
– Max: for a trailer length greater than 9 metres.

86
Driving
The message "Vehicle close" is displayed.Level 2 (red): visual and audible alert,
signalling that a collision is imminent.
The message "Brake! " is displayed.
Level 3: finally, in some cases, a haptic alert
in the form of micro-braking can be given,
confirming the risk of collision.
Where the speed of your vehicle is too
high approaching another vehicle, the
first level of alert may not be displayed: the
level 2 alert may be displayed directly.
Important: the level 1 alert is never displayed
for a stationary obstacle or when the " Close"
trigger threshold has been selected.
Intelligent emergency
braking assistance
If the driver brakes, but not sufficiently to avoid a
collision, this system will supplement the braking,
within the limits of the laws of physics.
This assistance will only be provided if the driver
presses the brake pedal.
Active Safety Brake

This function, also called automatic emergency
braking, intervenes following the alerts if the
driver does not react quickly enough and does
not operate the vehicle's brakes.
It aims to reduce the speed of impact or avoid a
collision where the driver fails to react.
Operation
The system operates under the following
conditions:
– The vehicle's speed does not exceed 50 mph
(80 km/h) when a stationary vehicle is detected.
– The vehicle's speed is between 3 mph and
53 mph (5 km/h and 85 km/h) when a moving
vehicle is detected.
This warning lamp flashes (for about 10 seconds) once the function is acting
on the vehicle's brakes.
With a manual gearbox, in the event of automatic
emergency braking until the vehicle comes to a
complete stop, the engine may stall.
The driver can maintain control of the vehicle at any time by sharply turning the
steering wheel and/or pressing the
accelerator pedal.
Operation of the function may be felt by
slight vibration in the brake pedal.
If the vehicle comes to a complete stop, the
automatic braking is maintained for 1 to 2
seconds.
Malfunction
In the event of a system malfunction, this
warning lamp comes on on the instrument
panel, accompanied by an onscreen message
and an audible signal.
Contact a CITROËN dealer or a qualified
workshop to have the system checked.
If these warning lamps come on
after the engine has been switched
off and then restarted, contact a CITROËN
dealer or a qualified workshop to have the
system checked.
Audible rear parking sensors
Refer to the General recommendations on the
use of driving and manoeuvring aids .


If fitted to your vehicle, the system consists of 4
proximity sensors installed in the rear bumper.
They detect any obstacle, e.g. person, vehicle,
tree, barrier, which is behind the vehicle while
manoeuvring.
Certain types of obstacle detected at the
beginning of the manoeuvre will no longer be
detected at the end of manoeuvre if they are
located in the blind spots between and under the
sensors. Examples: stake, roadworks cone or
pavement post.
The rear parking sensors may be associated
with the reversing camera.
Switching on
► Engage reverse gear with the gear lever.

In the event of a breakdown
► Connect the red cable to metallic terminal A,
then to the (+) terminal of backup battery B.
► Connect one end of the green or black cable
to the negative (-) terminal of backup battery B.
► Connect the other end of the green or black
cable to earth point C of your vehicle.
► Operate the starter, let the engine run.
► Wait for the engine to return to idle and
disconnect the cables.
Charging the battery using a
battery charger
► Access the battery, located in the left-hand
front floor.
► Disconnect the battery.
► Follow the instructions for use provided by
the manufacturer of the charger.
► Reconnect starting with the (-) terminal.
► Check the cleanliness of the terminals. If they
are covered with sulphate (whitish or greenish
deposit), remove and clean them.
The charging operation must be carried out in a well-ventilated area and away
from naked flames and any sources of sparks
so as to avoid the risk of explosion or fire.
Do not try to recharge a frozen battery: it
must first be thawed to avoid the risk of
explosion. If it has frozen, before charging it,
have the battery checked by a specialist who
will check that the interior components have
not been damaged and that the container is
not cracked, which would involve a risk of
leakage of toxic and corrosive acid.
Perform a slow charge at low amperage for
about 24 hours maximum to avoid damaging
the battery.
The presence of this label, in particular with the Stop & Start system, indicates
the use of a 12 V lead-acid battery with
special technology and specification; the
involvement of a CITROËN dealer or a
qualified workshop is essential when
replacing or disconnecting the battery.
After refitting the battery at a CITROËN dealer or a qualified workshop, the Stop
& Start system will only be active after a
continuous period of immobilisation of the
vehicle, a period which depends on the
climatic conditions and the state of charge of
the battery (up to about 8 hours).
