Driving
Manoeuvring aids
The driver must always check the 
surroundings of the vehicle before and during 
the whole manoeuvre, in particular using the 
mirrors.
Radar(s)
The operation of the radar(s), along with 
any associated functions, may be affected 
by the accumulation of dirt (e.g.
  mud, ice), 
in poor weather conditions (e.g.
  heavy rain, 
snow), or if the bumpers are damaged.
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(s).
 
 
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 (e.g.
  inadequate street lighting, 
heavy rain, thick fog, snowfall), dazzle 
(e.g. 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/Pedal trims
The use of mats or pedal trims 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
 .

This system:
– warns the driver that their vehicle is at risk of 
collision with the vehicle in front, a pedestrian or
, 
depending on version, a cyclist.
–
 
reduces the vehicle's speed to avoid a 
collision or limit its severity
.
The speed will be reduced by a maximum of 12 mph (20   km/h) (versions 
with camera only) or by a maximum of 31 
mph (50
  km/h) (versions with camera and 
radar).
The system also takes motorcyclists into  account.
This system is comprised of three functions:
–
 
Collision 
 Risk Alert.
–
 
Intelligent emergency braking assistance 
(iEBA).
–
 
Active Safety Brake (automatic emergency 
braking).
 
 
The vehicle has a multifunction camera located 
at the top of the windscreen and, depending on 
version, a radar located in the front bumper.
This system does not replace the need  for driver vigilance.
This system is designed to assist the driver 
and improve road safety.
It is the driver's responsibility to continuously 
monitor traffic conditions in accordance with 
applicable driving regulations.
As soon as the system detects a  potential collision, it prepares the braking 
circuit. This may cause a slight noise and a 
slight sensation of deceleration.
Deactivation/Activation
By default, the system is automatically activated 
at every engine start.
With Touch screen BLUETOOTH audio 
system or MyCitroën Play
The settings are changed via the  Driving 
touch screen menu.
With MyCitroën Drive
The settings are changed via the  Vehicle 
touch screen menu.
With MyCitroën Drive Plus
The settings are changed via the  ADAS 
touch screen application.
Deactivation of the system is signalled by 
the illumination of this warning lamp, 
accompanied by the display of a message.
Operating conditions and 
limits

Seat belts fastened for all passengers.
Stabilised speed on roads with no or low 
curvature.
This warning lamp lights up on the  instrument panel without any additional 
message, to indicate that the automatic braking 
system is not available.
This is a normal behavior indicating that a 
condition is not fulfilled and which does not 
request the support of a workshop.
In any situations with ignition on where automatic 
braking presents a risk, deactivating the system 
is recommended, for instance:

Practical information
7Traction battery
This battery stores the energy that powers 
the electric motor and the thermal comfort 
equipment in the passenger compartment. It is 
discharged during use, and must therefore be 
regularly recharged. There is no need to wait 
for the traction battery to fall to its reserve level 
before recharging.
The range of the battery may vary according 
to the type of driving, the route, the use of 
thermal comfort equipment and the ageing of its 
components.
The lifespan of the traction battery depends on multiple factors, such as 
climatic conditions, distance travelled and 
how often it has been fast-charged.
To preserve the mileage of your vehicle  and the durability of your traction battery, 
CITROËN recommends that you:
–
 
Do not fully charge the battery of your 
electric vehicle daily (charge the traction 
battery below 80% as often as possible).
–
 
Do not completely discharge the battery
 .
–
 
Do not store the vehicle for a long period 
of non-use (more than 12
  hours) when the 
traction battery has a low or high charge level. 
Prefer a charge level between 20 and 40%.
–
 
Limit the use of fast charging.
–
 
Do not expose the vehicle to temperatures 
below -30°C and above +60°C for more than 
24
 
hours.
– Avoid charging the vehicle at negative 
temperatures (except if the vehicle ran more 
than 20   minutes) or above +30°C.
–
 
Do not use the vehicle's traction battery as 
a generator of energy
.
–
 
Do not use a generator to recharge your 
vehicle's traction battery
.
In the event of damage to the traction 
battery
It is strictly prohibited to work on the vehicle 
yourself.
Do not touch liquids coming from the battery, 
and in the event of skin contact with these 
products, wash abundantly with water and 
contact a doctor as soon as possible.
Contact a CITROËN dealer or a qualified 
workshop to have the system checked.
Disposal of the traction battery
The traction battery is designed for the life of the 
vehicle if the recommendations of CITROËN are 
followed.
If it becomes necessary to replace the battery, 
contact the CITROËN dealer for instructions on 
its disposal. Improper disposal carries the risk of 
severe burns, electric shock, and damage to the 
environment.

Towing device
Load distribution
►  Distribute the load in the trailer so that the 
heaviest items are as close as possible to the 
axle, and the nose weight approaches the 
maximum permitted without exceeding it.
Air density decreases with altitude, thus reducing 
engine performance. 
The maximum towable load 
must be reduced by 10% per 1,000
  metres of 
altitude.
Use genuine towing devices and wiring 
harnesses approved by CITROËN. We 
recommend having them fitted by a CITROËN 
dealer or a qualified workshop.
If not fitted by a CITROËN dealer, they must 
still be fitted in accordance with the vehicle 
manufacturer's instructions.
Certain driving or manoeuvring aid functions 
are automatically deactivated while an 
approved towing system is in use.
Comply with the maximum authorised 
towable weight, as indicated on your 
vehicle's registration certificate, on the 
manufacturer's label and in the  Technical 
data section of this guide.
If using accessories attached to the 
towing device (e.g.   bicycle carriers, tow 
boxes):
–
 
Comply with the maximum authorised nose 
weight.
–
 
Do not transport more than 4 conventional 
bicycles or 2 electric bicycles.
When loading bicycles onto a bicycle carrier 
on a towball, be sure to place the heaviest 
bicycles as close as possible to the vehicle.
Observe the legislation in force in the 
country where you are driving.
Electric motor
An electric vehicle cannot under any 
circumstances be fitted with a towing device.

As a safety measure and to avoid  damaging the roof, it is essential to use 
transverse roof bars approved for your 
vehicle.
Observe the instructions on fitting and use 
contained in the guide supplied with the roof 
bars.
Maximum load distributed over the 
transverse roof bars, for a loading height 
not exceeding 40 cm (except bicycle carrier): 
80
 
kg.
As this value may change, please verify the 
maximum load quoted in the guide supplied 
with the roof bars.
If the height exceeds 40 cm, adapt the speed 
of the vehicle to the profile of the road to 
avoid damaging the roof bars and the fixings 
on the vehicle.
Be sure to refer to national legislation in order 
to comply with the regulations for transporting 
objects that are longer than the vehicle.
Recommendations
Distribute the load uniformly, taking care 
to avoid overloading one of the sides.
Arrange the heaviest part of the load as close 
as possible to the roof.
Secure the load firmly.

Practical information
Oil grade
Before topping up or changing the 
engine oil, check that the oil is suitable 
for your engine and complies with the 
recommendations in the service schedule 
supplied with the vehicle (or available from 
your CITROËN dealer or qualified workshop).
Use of non-recommended oil may invalidate 
your warranty in the event of engine failure.
Topping up the engine oil level
For the location of the engine oil filler cap, please 
refer to the corresponding engine compartment 
illustration.
►
 
Add oil in small quantities, avoiding any spills 
on engine components (risk of fire).
►
 
W
 ait a few minutes before checking the level 
again using the dipstick.
►
 
T
 op up the level if necessary.
►
 
After checking the level, carefully screw the 
oil filler cap back on
  and replace the dipstick in 
its tube.
The oil level indication displayed on the  instrument panel when the ignition is 
switched on is not valid for 30 minutes 
following an addition of oil. 
Brake fluid
The level of this fluid should be  close to 
the "MAX" mark. If not, check the brake 
pads for wear.
To know how often the brake fluid should be 
replaced, refer to the manufacturer's servicing 
schedule.
Clean the cap before removing it to refill. 
Use only DOT4 brake fluid from a sealed 
container.
Engine coolant
(Petrol or Diesel)
It is normal to top up this fluid between 
two services.
The check and top-up must only be done with 
the engine cold.
A level of coolant that is too low risks causing 
major damage to the engine; the coolant level 
must be close to the "MAX" mark without ever 
going above it.
If the level is close to or below the " MIN" mark, it 
is essential to top it up.
When the engine is hot, the temperature of the 
coolant is regulated by the fan.
As the cooling system is pressurised, wait at 
least one hour after switching off the engine 
before carrying out any work.
In order to avoid the risk of scalding if you need 
to top up in an emergency, wrap a cloth around 
the cap and unscrew the cap by two turns to 
allow the pressure to drop.
Once the pressure has dropped, remove the cap 
and top up to the required level.
(Electric)
Do not top up the coolant. 
If the level is close to or below 
the   "MIN"   mark, it is essential to contact a 
CITROËN dealer or a qualified workshop.
Screenwash fluid
Top up to the required level when  necessary.
Fluid specification
The fluid must be topped up with a pre-mixed 
product.
In winter (temperatures below zero), a fluid 
containing an anti-freeze agent which is 
appropriate for the temperature conditions 
must be used in order to protect the system's 
components (pump, tank, ducts, jets).
Filling with pure water is prohibited in all 
circumstances (risk of freezing, 
limescale, etc.).
