Driving
6Towing
Driving with a trailer places greater
demands on the towing vehicle and
particular care must be taken.
Do not exceed the maximum towable
weights.
At altitude: reduce the maximum load by
10% per 1,000 metres of altitude; the lower
air density at high altitudes decreases engine
performance.
New vehicle: do not tow a trailer until the
vehicle has 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 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.



Pay constant 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
Using the engine brake is recommended to limit
the overheating of the brakes. Braking distances
are increased when towing a trailer.
Side wind
Bear in mind that the vehicle will be more
susceptible to wind when towing.
Anti-theft protection
Electronic immobiliser
The keys contain a code, which must be
recognised by the vehicle before starting is
possible.
If the system malfunctions, indicated by the
display of a message, the engine will not start.
Contact a CITROËN dealer.
Starting/Switching off the
engine with Keyless Entry
and Starting
The electronic key must be present in the passenger compartment.
If the electronic key is not detected, a
message is displayed.
Move the electronic key so that the engine
can be started or switched off.

Driving
coming out of reverse gear or turning the
steering wheel.
Restarting the engine (START mode)
The engine automatically restarts as soon as the
driver indicates the intention of moving off again:

With the selector in mode
D or M: with the
brake pedal released.


With the selector in mode
N and the brake
pedal released: when you place the gear
selector in mode D or M.


With the selector in mode
P and the brake
pedal depressed: when you place the gear
selector in mode R, N, D or M.


With reverse gear engaged.
Special cases
The engine will restart automatically if the
conditions for operation are met again and in the
following case:

Automatic gearbox in mode N

, vehicle speed
exceeds 0.6 mph (1 km/h).
In this case, this indicator lamp flashes for
a few seconds, then goes off.
Malfunctions
In the event of a fault with the system, this
warning lamp flashes for a few moments
on the instrument panel, then remains on,
accompanied by the display of a message.
Have it checked by a CITROËN dealer or a
qualified workshop.
The vehicle stalls in STOP mode
All of the instrument panel warning lamps come
on if there is a fault.


Switch off the ignition then start the engine
again with the " ST

ART/STOP" button.
12 V battery
The Stop & Start system requires a
12 V battery of specific technology and
specification.
All work must be carried out only by a
CITROËN dealer or a qualified workshop
Tyre under-inflation detection
This system alerts the driver when one or more
tyres have a drop in pressure.
The alert is raised when the vehicle is moving,
not when stationary.
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.
It takes the last values

stored during
the

reinitialisation request into account. It is
therefore essential that the tyre pressure is
correct during the operation. This operation is
the driver’s responsibility.
The tyre under-inflation detection cannot, in any circumstances, 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), especially 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 energy consumption.
The inflation pressures defined 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 monthly
when the tyres are "cold" (vehicle stopped for
1 hour or after a journey of less than 6 miles
(10

km) at moderate speeds).
Otherwise, add 0.3 bar to the pressures
shown on the label.

6Deactivation/Activation
By default, the system is automatically activated
at every engine start.
It is configured in 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
Vehicle moving forward without trailer.
Brake system operational.
ASR / ESP system activated.
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 via ADAS touch screen application is
recommended, for instance:


T

owing a trailer (particularly a trailer without its
own braking system).


Carrying long objects on roof bars.



Driving with snow chains.
– Using an automatic car wash.
– Performing any maintenance (e.g. changing a
wheel, working underhood).


Placing the vehicle on a rolling bench in a
workshop.



T
owing the vehicle.


Following a front bumper deformation (version
with radar).



Following
an impact to the windscreen close to
the detection camera.
The system is automatically deactivated if:


A

spare wheel with a too small diameter is
detected.


A

fault with the brake pedal switch or with
the right or left brake lamp is detected.


A

fault in the sensors, in the electronic or in
the brake system is detected.


A

trailer is detected by the equipped vehicle
hitch (with an electrical connection plug).
The system diagnoses permanently its capability and may inhibit itself without
specific driver indication, if the system is
outside of the regular operating conditions.
Examples: sensor initialization, board voltage
out of regular range, activation of stability
system…
Therefore the system may not be available
just after starting the vehicle.
It can be dangerous to drive if the brake
lamps are not in perfect working order.
The driver must not load his vehicle excessively (respect of MTAC values,
MTRA values and loading height on roof
bars).
Following an impact (e.g. a collision), the
system is automatically deactivated.
Have it checked by a CITROËN dealer or a
qualified workshop.
Collision Risk Alert
This function warns the driver if there is a risk
of collision with the preceding vehicle, or with a
pedestrian or cyclist.
Modifying the alert trigger threshold
The trigger threshold determines the sensitivity
with which the function warns of the risk of
collision.
It is configured in the ADAS touch screen
application.


Select one of the 3 preset thresholds: “ Far

”,
“Medium” or “Near”.
The selected threshold is memorised when the
ignition is switched off.
Operation
Depending on the collision risk detected by the
system and the alert trigger threshold chosen

Driving
6Operation
The system operates subject to the following
conditions:

The vehicle's speed does not exceed 50
mph (80 km/h) when a pedestrian or a cyclist is
detected.



The vehicle's speed does not exceed 50 mph
(80 km/h) when a stationary vehicle is detected.



The vehicle's speed is between 6 mph and
53 mph (10

km/h and 85 km/h) (versions with
camera only) or 87 mph (140 km/h) (versions
with camera and radar) when a moving vehicle
is detected.
This warning lamp flashes (for approximately 10 seconds) as soon as
the function applies the vehicle’s brakes. During
the flashing time, the function is not available.
In the event of automatic emergency braking,
keep the brake pedal depressed, also after a
complete stop is reached, to prevent the vehicle
from rolling away.
The driver can override the "automatic emergency braking" at any time by firmly
turning the steering wheel and/or firmly
depressing the accelerator pedal.
The brake pedal may feel hard and vibrate slightly while the function is
operating.
If the vehicle comes to a complete stop,
automatic braking is maintained for 1 to 2
seconds.
Turning scenarios
Crossing road with another vehicle

The system may operate when the vehicle is
turning and detects another vehicle, on the
adjacent lane, approaching from the opposite
direction if:


The corresponding direction indicator is
activated.



Then the vehicle is about to cross the path of
another vehicle.



The vehicle speed is between 3 and 12
mph
(5 and 20
km/h).


A
collision on the side of the other vehicle is
probable.
Crossing road with a pedestrian

The system may operate when the vehicle
is turning left or right and detects a crossing
pedestrian if:


The pedestrian is crossing in front of the
vehicle.



The pedestrian can clearly be detected by the
sensors.



The scenery is detectable by the sensors (e.g.
brightness, contrast vs background).



The vehicle speed is between 3 and 15
mph
(5 and 25
km/h).
Malfunction
This warning lamp lights up on the instrument panel with the message
"Sensor blind" in certain cases. With the variant
"camera only", the system is deactivated. With
the variant "camera and radar", the system may
continue to operate in a degraded mode. This
may be caused by a reduced visibility (rain, fog,
snow, blending by low sun…) or by a real sensor
blockage. In this case, stop the vehicle and verify

Event data recorders
11Recording event data
Electronic control units are installed in your
vehicle. These control units process data
received from the vehicle's sensors, for example,
or data they generate themselves or exchange
with each other. Some of these control units are
required for the correct operation of your vehicle,
some others assist you while driving (driving or
manoeuvring aids), while others provide comfort
or infotainment functions.
The following contains general information about
how data is processed within the vehicle.
You will find additional information about the
specific data which is downloaded, stored
and transmitted to third parties and what it is
used for in your vehicle under the keyword
"Data protection". This information is directly
associated with the references for the functions
in question contained in the corresponding
vehicle handbook, or in the general terms and
conditions of sale.
This information is also available online.
Vehicle operating data
The control units process the data used for the
operation of the vehicle.
This data includes, for example:

Information about the state of the vehicle (e.g.
speed, travel time, lateral acceleration, wheel
rotation rate, fastened seat belts display). –


Environmental conditions (e.g. temperature,
rain sensor
, distance sensor).
As a general rule, this data is temporary, is
not stored for longer than one operating cycle
and is only used within the vehicle itself. The
control units often record this data (including the
vehicle's key). This function allows either the
temporary or permanent storage of information
about the state of the vehicle, stresses on
components, servicing requirements, as well as
events and technical errors.
Depending on the vehicle's equipment level, the
data stored is as follows:

Operating state of system components (e.g.
filling level, tyre pressures, battery charge
status).


Faults and malfunctions in important system
components (e.g. lamps, brakes).


System reactions in specific driving situations
(e.g. deployment of an airbag, triggering of
stability control and braking systems).


Information about events which have
damaged the vehicle.


For electric and rechargeable hybrid vehicles,
the traction battery charge level and the
estimated driving range.
In particular circumstances (e.g. if the vehicle
has detected a malfunction), it may be necessary
to record data which would otherwise simply not
be stored.
When taking your vehicle in for servicing (e.g.
repairs, maintenance), the stored operating
data may be read along with the vehicle's identification number and used if necessary

.
The personnel working for the servicing network
(e.g. garages, manufacturers) or third parties
(e.g. roadside assistance agents) may read
the vehicle's data. This also applies to work
carried out under warranty and quality assurance
measures.
This data is generally read via the OBD
(On-Board Diagnostics) port fitted by law to
the vehicle. It is used to report on the technical
state of the vehicle or its components and
facilitates the diagnosis of malfunctions, in
compliance with warranty obligations and for
quality improvement. This data, in particular the
information relating to stress on components,
technical events, operator errors and other
malfunctions, is sent to the Manufacturer, if
necessary, along with the vehicle's identification
number. The Manufacturer's liability may also be
engaged. The Manufacturer may also use the
operating data taken from the vehicle for product
recalls. This data may also be used to check the
customer's warranty and any claims made under
warranty.
Any malfunctions stored in the vehicle may be
reset by an after-sales service company during
servicing or repair work, or at your request.
