Safety
– a child or an animal in a vehicle which is
exposed to the sun, with the windows closed,
– the keys within reach of children inside the
vehicle.
Child seat at the front

► Adjust the front passenger seat to the
highest and fully back longitudinal position ,
with the backrest straightened.
"Rearward facing"

The front passenger airbag must be deactivated. Otherwise, the child risks
being seriously injured or killed if the
airbag is deployed .
A damaged door or any unauthorised or
incorrectly executed work (modification or
repair) on the front doors or their interior trim
could compromise the operation of these
sensors - risk of malfunction of the lateral
airbags!
Such work must only be done by a CITROËN
dealer or a qualified workshop.
Curtain airbags
Do not fix or attach anything to the roof,
as this could cause head injuries when the
curtain airbag is deployed.
Child seats
The legislation on carrying children is specific to each country. Refer to the
legislation in force in your country.
For maximum safety, please observe the
following recommendations:
–

In accordance with European regulations, all
children under the age of 12 or less than one
and a half metres tall must travel in approved
child seats suited to their weight , on seats
fitted with a seat belt or ISOFIX mountings.
–


Statistically
, the safest seats in your
vehicle for carrying children are the rear
seats.
– A child weighing less than 9 kg must travel
in the "rearward facing" position both in the
front and in the rear.
It is recommended that children travel
on the rear seats of the vehicle:
–

"rearward facing" up to the age of 3,
–

"forward facing" over the age of 3.
Make sure that the seat belt is correctly
positioned and tightened.
For child seats with a support leg, ensure that
the support leg is in firm and steady contact
with the floor.
Advice
An incorrectly installed child seat compromises the child's safety in the
event of an accident.
Ensure that there is no seat belt or seat belt
buckle under the child seat, as this could
destabilise it.
Remember to fasten the seat belts or the
harness of child seats, keeping the slack
relative to the child's body to a minimum,
even for short journeys.
When installing a child seat using the seat
belt, ensure that the seat belt is tightened
correctly on the child seat and that it secures
the child seat firmly on the seat of the vehicle.
If the passenger seat is adjustable, move it
forwards if necessary.
Remove the head restraint before
installing a child seat with a backrest on a
passenger seat.
Ensure that the head restraint is stored or
attached securely to prevent it from being
thrown around the vehicle in the event of
sharp braking. Refit the head restraint once
the child seat has been removed.
Children at the rear
A child seat with ISOFIX or i-Size
mountings must never be installed on the
centre rear passenger seat.
Installing a booster seat
The chest part of the seat belt must be
positioned on the child's shoulder without
touching the neck.
Ensure that the lap part of the seat belt
passes correctly over the child's thighs.
Use a booster seat with backrest, equipped
with a belt guide at shoulder level.
Additional protections
To prevent accidental opening of the
doors and rear windows, use the "Child lock".
Take care not to open the rear windows by
more than one third.
To protect young children from the rays of the
sun, fit side blinds on the rear windows.
As a safety precaution, do not leave:
–

a child alone and unattended in a vehicle,

automatically to preserve the remaining battery
charge.
Switching off the engine leads to a loss
of braking assistance.
Starting the engine
Parking brake applied:
► With a manual gearbox, place the gear lever
in neutral then depress the clutch pedal fully.
► With an automatic gearbox, place the gear
selector in mode N or P then depress the brake
pedal fully.
► Insert the key into the ignition switch; the
system recognises the code.
► Unlock the steering column by simultaneously
turning the steering wheel and the key.
In certain cases, you may have to apply
significant force to move the steering
wheel (wheels on full lock, for example).
► With a petrol engine , operate the starter
motor by turning the key to position 3 without
pressing the accelerator pedal, until the engine
starts. Once the engine starts, release the key.
With petrol engines , after a cold start,
pre-heating the catalytic converter can
cause clearly-felt engine vibrations when
stationary, with the engine running, for
anything up to two minutes (accelerated idle
speed).
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 causes the coolant
temperature to increase. The maximum towable
load depends on the gradient and the exterior temperature. The fan’s cooling capacity does not
increase with engine speed.
►

Reduce speed and lower the engine speed to
limit the amount of heating produced.
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.
Brakes
Braking distances are increased when towing a
trailer. To avoid overheating the brakes, the use
of engine braking is recommended.
Side wind
Bear in mind that the vehicle will be more
susceptible to wind when towing.
Anti-theft protection
Electronic immobiliser
The keys include an electronic engine
immobiliser system, which secret code must be
recognised in order for starting to be possible.
If the system malfunctions, indicated by the
display of a message, the engine will not start.
Contact the CITROËN dealer.
Starting / Switching off the
engine with the key
Key ignition switch

It has 3 positions:
– position 1 (Stop): inserting and removing the
key, steering column locked.
–
position 2 (Ignition on) : steering column
unlocked, ignition on, Diesel preheating, engine
running,
–
position 3 (Starting).
Avoid attaching heavy objects to the key
or the remote control, which would weigh
down on its blade in the ignition switch and
could cause a malfunction.
Ignition on position
It allows the use of the vehicle's electric
equipment or portable devices to be charged.
Once the state of charge of the battery drops to
the reserve level, the system switches to energy
economy mode : the power supply is cut off

Driving
The vehicle stalls in STOP mode
All of the instrument panel warning lamps come
on if there is a fault.
The Stop & Start system requires a 12 V battery of specific technology and
specification.
All work concerning the battery must be
carried out only by a CITROËN dealer or a
qualified workshop.
Tyre under-inflation detection
This system automatically checks the pressures
of the tyres while driving.
It compares the information given by the wheel
speed sensors with reference values, which
must be reinitialised every time the tyre
pressures are adjusted or a wheel changed.
The system triggers an alert as soon as it
detects a drop in the inflation pressure of one or
more tyres.
Under-inflation detection 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.
The inflation pressures specified for the vehicle can be found on the tyre pressure
label.
For more information on the Identification
markings, refer to the corresponding section.
Checking tyre pressures
This check should be done when the
tyres are "cold" (vehicle stopped for 1 hour or

Speed Limit Recognition
and Recommendation
Refer to the General recommendations on the
use of driving and manoeuvring aids.


This system displays the maximum authorised
speed in the instrument panel, according to
the speed limits in the country in which you are
driving, using:
– Speed limit signs detected by the camera.
– Speed limit details from the navigation system
mapping.
Navigation mapping should be regularly
updated in order to receive accurate
speed limit information from the system.
– Signs indicating an intersection area detected
by the camera.
If the front bumper is to be repainted, contact
a CITROËN dealer or a qualified workshop;
certain types of paint could interfere with the
operation of the radar.


Driving aids camera
This camera and its associated functions
may be impaired or not work if the windscreen
area in front of the camera is dirty, misty,
frosty, covered with snow, damaged or
masked by a sticker.
In humid and cold weather, demist the
windscreen regularly.
Poor visibility (inadequate street lighting,
heavy rain, thick fog, snowfall), dazzle
(headlamps of an oncoming vehicle, low sun,
reflections on a damp road, leaving a tunnel,
alternating shade and light) can also impair
detection performance.
In the event of a windscreen replacement,
contact a CITROËN dealer or a qualified
workshop to recalibrate the camera;
otherwise, the operation of the associated
driving aids may be disrupted.
Other cameras
The images from the camera(s)
displayed on the touch screen or on the
instrument panel may be distorted by the
terrain.
In the presence of areas in shade, or in
conditions of bright sunlight or inadequate
lighting, the image may be darkened and with
lower contrast.
Obstacles may appear further away than they
actually are.
Sensors
The operation of the sensors, as well as
any associated functions, may be disrupted
by noise pollution such as that emitted by
noisy vehicles and machinery (e.g. lorries,
pneumatic drills), by the accumulation of
snow or dead leaves on the road or in the
event of damaged bumpers and mirrors.
When reverse gear is engaged, an audible
signal (long beep) indicates that the sensors
may be dirty.
A front or rear impact to the vehicle can
upset the sensors’ settings, which is not
always detected by the system: distance
measurements may be distorted.
The sensors do not systematically detect
obstacles that are too low (pavements, studs)
or too thin (trees, posts, wire fences).
Certain obstacles located in the sensors’ blind
spots may not be detected or may no longer
be detected during the manoeuvre.
Certain materials (fabrics) absorb sound
waves: pedestrians may not be detected.
Maintenance
Clean the bumpers and door mirrors and
the field of vision of the cameras regularly.
When washing your vehicle at high pressure,
direct the spray from at least 30
cm away
from the radar, sensors and cameras.
Mats
The use of mats not approved by
CITROËN may interfere with the operation of
the speed limiter or cruise control.
To avoid any risk of jamming the pedals:
–

Ensure that the mat is secured correctly
.
–

Never fit one mat on top of another
.
Units of speed
Ensure that the units of speed displayed
in the instrument panel (mph or km/h) are
those for the country you are driving in.
If this is not the case, when the vehicle is
stationary, set the display to the required
units of speed so that it complies with what is
authorised locally.
In case of doubt, contact a CITROËN dealer
or a qualified workshop.

workshop to have the system checked.
The system may suffer temporary interference in certain weather conditions
(rain, hail, etc.).
In particular, driving on a wet surface or
moving from a dry area to a wet area can
cause false alerts (for example, the presence
of a fog of water droplets in the blind spot can
be interpreted as a vehicle).
In bad or wintry weather, ensure that the
sensors are not covered by mud, ice or snow.
Take care not to cover the warning zone in
the door mirrors, or the detection zones on
the front and rear bumpers with adhesive
labels or other objects; they may hamper
correct operation of the system.
