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

Practical information
– The towball must not be able to move in
its carrier; test by attempting to shake it with
your hand.
If the towball is not locked, the trailer can
become detached - risk of an accident!
During use
Never release the locking system with a
trailer or load carrier on the towball.
Never exceed the maximum authorised
weight for the vehicle - the Gross Train
Weight or GTW.
Always comply with the maximum authorised
load on the towing device: if it is exceeded,
this device may become detached from the
vehicle - risk of an accident!
Before driving, check the headlamp height
adjustment and check that the lamps on the
trailer operate correctly.
For more information on Headlamp height
adjustment, refer to the corresponding
section.
After use
When travelling without a trailer or
load carrier, remove the towball and fit the
protective plug into the carrier, to provide
clear visibility of the number plate and/or its
lighting.
Fitting the towball

► Below the rear bumper , remove the protective
plug 2 from the carrier 1.
►

Insert the end of the towball
5 into the carrier
1 and push it upwards; it will lock into position
automatically.


► The wheel 6 rotates a quarter turn anti-
clockwise; take care to keep your hands clear!


► Check that the mechanism has correctly
locked into place and that the green mark on
the wheel is aligned with the white mark on the
towball (position A
).
►

Close the lock 7

using the key.
►

Remove the key
. The key cannot be removed
while the lock is open.
►

Lower the cap to protect the lock.

154
Practical information
► Replace the protective plug 2 into the
carrier 1.
►

Stow the towball in its bag to protect it from
knocks and dirt.
Maintenance
Correct operation is only possible if the towball
and its carrier are kept clean.
Before cleaning the vehicle with a high-pressure
jet wash, the towball must be removed and the
protective plug fitted to the carrier.
Work on the towing device
Contact a CITROËN dealer or a qualified
workshop.
Roof bars
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.
Fitting on longitudinal bars

The transverse bars must be fixed at the
markings located on the longitudinal bars.
Fitting directly to the roof

You must only attach the transverse bars to
the four fixing points located on the roof frame.
These points are concealed by the vehicle doors
when the doors are closed.
The roof bar fixings have a stud which must be
inserted into the opening of each fixing point.
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.
Drive gently: the vehicle will be more
susceptible to the effects of side winds and its
stability may be affected.
Regularly check the security and tight
fastening of the roof bars, at least before each
trip.
