Driving
6Effective eco-driving saves fuel; accelerate
progressively, anticipate the need to slow down
and adapt your speed to suit the situation.
Indicate changes of direction well in advance so
that you are seen by other road users.
Take care
The tyres must be inflated to at least the
pressures indicated on the label, even over-
inflated by 0.2 to 0.3 bar for long journeys.
On flooded roads
We strongly advise against driving on flooded
roads, as this could cause serious damage to
the engine or gearbox, as well as to the electrical
systems of your vehicle.


If you are obliged to drive on a flooded road:
► check that the depth of water does not
exceed 15 cm, taking account of waves that
might be generated by other users,
► deactivate the Stop & Start function,
► drive as slowly as possible without stalling. In
all cases, do not exceed 6 mph (10 km/h),
► do not stop and do not switch off the engine.
On leaving the flooded road, as soon as safety
conditions allow, make several light brake
applications to dry the brake discs and pads.
If in doubt about the state of your vehicle,
contact a CITROËN dealer or a qualified
workshop.
In case of towing
Driving with a trailer places greater
demands on the towing vehicle and
requires extra care from the driver.
Respect the maximum towable weights.
At altitude: reduce the maximum load by
10% per 1,000 metres of altitude; the density
of the air decreases with altitude and the
performance of the engine reduces.
New vehicle: do not pull a trailer before
having driven at least 620 miles (1,000
kilometres).
If the outside temperature is high, let the
engine idle for 1 to 2 minutes after the
vehicle comes to a stop, to help it to cool.
Before setting off
Nose weight
► Distribute the load in the trailer so that the
heaviest items are as close as possible to the
axle and the nose weight (at the point where it
joins your vehicle) approaches the maximum
permitted without exceeding it.
Tyres
► Check the tyre pressures of the towing
vehicle and of the trailer, observing the
recommended pressures.
Lighting
► Check the electrical signalling on the trailer
and the headlamp beam height of your vehicle.
If a genuine CITROËN towing device is
used, the rear parking sensors will be
deactivated automatically to avoid the audible
signal.
When driving
Cooling
Towing a trailer uphill increases the temperature
of the coolant. The maximum towable load
depends on the gradient and the exterior
temperature. The cooling capacity of the fan
does not increase with engine speed.
► Reduce speed and lower the engine speed,
so as to limit the heating-up.
In all cases, pay attention to the coolant
temperature.
If this warning lamp and the STOP
warning lamp come on, stop the vehicle
and switch off the engine as soon as possible.

68
Driving
When the battery is in standby mode,
access to the vehicle is only possible by
unlocking the mechanical lock on the driver's
side door.
After a battery standby, the information (time, date, radio stations, etc.) is
memorised.
To remove the battery from standby mode:
► Turn the key to the MAR - ON position.
► Start the vehicle normally ( AV V position).
Parking brake
Application
► Apply the parking brake to immobilise the
vehicle.
► Check that the parking brake is correctly
applied before leaving the vehicle.
Apply the parking brake only when the
vehicle is stationary.
When parking on a slope, turn your
wheels towards the kerb and pull the
parking brake lever up.
There is no advantage in engaging a gear
after parking the vehicle, particularly if the
vehicle is loaded.
In the event of a failure of the
hydraulic braking system
While driving , to avoid any accidental
movement of the vehicle, use the parking
brake while depressing the brake pedal.
In this exceptional circumstance, it is
advisable to pull the parking brake up gently
so as not to block the rear wheels - risk of
skidding!
Release

► Pull the lever up gently and press the button
to release the parking brake.
When the vehicle is being driven, this
warning lamp coming on indicates that
the parking brake is still applied or has not been
fully released.
Manual gearbox
To change gear easily, always fully depress the
clutch pedal.
To prevent the mat from becoming caught under
the pedal:
– ensure that the mat is positioned correctly,
– never fit one mat on top of another.
Avoid leaving your hand on the gear knob as
the force exerted, even if slight, may wear the
internal components of the gearbox over time.
Engaging reverse gear

► Lift the ring under the knob to engage reverse
gear.
Never engage it until the vehicle has
come to a complete stop.
The movement must be done slowly to reduce
the noise when engaging reverse gear.
If fitted to the vehicle, the parking
sensors are activated when reverse gear
is engaged; an audible signal sounds.
For more information on the Parking
sensors, refer to the corresponding section.
Gear shift indicator
Depending on version or engine, this system
reduces fuel consumption by recommending a
higher gear change.
Gear shift recommendations should not be
considered compulsory. 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.
The system cannot be deactivated.
Operation
The information appears in the instrument panel screen in the form of the SHIFT
indicator, accompanied by an upward arrow to
signal to the driver that they can change up.
The system adapts its gear shift recommendation according to the driving
conditions (slope, load, etc.) and the driver’s
requirements (power, acceleration, braking,
etc.).
The system never recommends engaging first
gear or reverse, or changing down.
Stop & Start
The Stop & Start function puts the engine temporarily into standby - STOP mode - during
phases when the vehicle is stopped (red lights,

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.

6Audible 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

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.

The proximity information is indicated by an
audible signal which becomes more rapid as the
vehicle approaches the obstacle.
When the distance between the rear of
the vehicle and the obstacle is less than
approximately 30 centimetres, the audible signal
becomes continuous.
Switching off
► Disengage reverse gear and shift to neutral.
Malfunction
If this warning lamp lights up on the
instrument panel, accompanied by a
message in the display, contact a CITROËN
dealer or a qualified workshop.
Reversing camera
Refer to the General recommendations on the
use of driving and manoeuvring aids .


If fitted to the vehicle, the camera is located at
the rear by the third brake lamp.


It transmits views to the screen installed in the
cab.
It can be activated or deactivated via the settings
menu of the touch screen audio and telematics
system.

88
Driving
This rear vision system is a driving aid. The
reversing camera may be associated with the
rear parking sensors.
Switching on
The camera comes into operation when reverse
gear is engaged and remains active up to
approximately 9 mph (15 km/h). It is deactivated
above 11 mph (18 km/h).
The camera also comes on with the vehicle
stationary, when the rear doors are opened.
Switching off
When engaging forward gear, the last image
remains displayed for approximately 5 seconds,
then goes out.
The last image also remains displayed in the
same way, with the vehicle stationary, when
closing the rear doors.
With optimum vehicle conditions (position
on the road, loading level) the maximum
area of visibility covered by the camera has a
field depth approximately 3 m long and 5.5 m
wide.
The area of visibility may vary depending on
the external weather conditions (brightness,
rain, snow, fog, etc.), the load in the vehicle
and the position of the vehicle on the road.
When cleaning the camera and the screen,
avoid using a detergent or a tool which may
scratch the glass.
Use a non-abrasive cloth or a small brush.
