Driving
6In the following cases, deactivating the system
via the vehicle's configuration menu is advised:
– towing a trailer,
– carrying long objects on roof bars or roof rack,
– with snow chains fitted,
– before using an automatic car wash, with the
engine running,
– before placing the vehicle on a rolling road in
a workshop,
– towed vehicle, engine running,
– following an impact to the windscreen close to
the detection camera.
It is automatically deactivated after
detection of a fault with the brake pedal
switch or with at least two brake lamps.
After an impact, the function automatically stops operating. Contact a
CITROËN dealer or a qualified workshop to
have the system checked.
It is possible that warnings are not given,
are given too late or seem unjustified.
The driver must always stay in control of their
vehicle and be prepared to react at any time
to avoid an accident.
Cases of non-detection by the system:
– Pedestrians, cyclists, animals, objects on the
road.
– Vehicles crossing your lane.
– Vehicles driving in the opposite direction.


Pay particular attention:
– When narrow vehicles (motorcycles)
are present and/or there are vehicles
staggered across the traffic lane.
– When entering a tunnel or crossing a
bridge.
When the driver must suspend the system:


– Vehicles in a tight bend.
– When approaching a roundabout.


– When a vehicle cuts in sharply between your
vehicle and the one in front.
Collision Risk Alert
It warns the driver that their vehicle is at risk of
collision with the vehicle in front.
Modifying the alert trigger threshold
This trigger threshold determines the sensitivity
with which the function warns of the risk of
collision.
The threshold is set via the vehicle configuration menu.
► Select one of the three pre-defined
thresholds:
– "Near ".
– "Normal".
– "Distant".
The last threshold selected is memorised when
the ignition is switched off.
Operation
Depending on the degree of risk of collision
detected by the system and the alert threshold
chosen by the driver, several different levels
of alert may be triggered and displayed in the
instrument panel.
They take account of the vehicle dynamics, the
speed of your vehicle and the one in front, the
environmental conditions and the operation of
the vehicle (cornering, actions on the pedals,
etc.) to trigger the alert at the best moment.
Level 1 (orange): visual alert only,
signalling that the vehicle in front is very
close.

Practical information
Before each use
Check that the towball is correctly locked,
verifying the follow points:
– the green mark on the wheel is in line with
the green mark on the towball,
– the wheel is in contact with the towball,
– the key lock is closed and the key removed;
the wheel can no longer be operated,
– the towball must not be able to move in its
carrier; test by shaking it with your hand.
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 Vehicle
Weight - GVW), the trailer, or the sum of the
two (the Gross Train Weight - GTW).
Following use
When travelling without a trailer or load on a
towbar-mounted carrier, the towball must be
removed and the protective plug inserted in the
carrier. This measure applies particularly where
the towball might obscure visibility of the number
plate or its lighting.
wheels, check that no part of the chain or its
fixings is in contact with the wheel rim.
Towing a trailer

The type-approved towable weights are entered
in your vehicle's registration certificate, as well
as on the manufacturer's plate.
For more information on the Technical
characteristics of the vehicle and
particularly on weights and towable loads,
refer to the corresponding section.
You will then have information on your vehicle's
ability to tow a trailer, a caravan, a boat, etc.
These values are also given in the sales
brochures.
We recommend using genuine CITROËN
towbars and their harnesses that have
been tested and approved from the design
stage of your vehicle, and having a CITROËN
dealer fit the towbar.
These genuine towbars are compatible with
the operation of the rear parking sensors and
the reversing camera, if your vehicle is so
equipped.
If the towbar is not fitted by a CITROËN
dealer, it must still be fitted in accordance with
the vehicle manufacturer's instructions.

In the event of a breakdown
► Connect the red cable to metallic terminal A,
then to the (+) terminal of backup battery B.
► Connect one end of the green or black cable
to the negative (-) terminal of backup battery B.
► Connect the other end of the green or black
cable to earth point C of your vehicle.
► Operate the starter, let the engine run.
► Wait for the engine to return to idle and
disconnect the cables.
Charging the battery using a
battery charger
► Access the battery, located in the left-hand
front floor.
► Disconnect the battery.
► Follow the instructions for use provided by
the manufacturer of the charger.
► Reconnect starting with the (-) terminal.
► Check the cleanliness of the terminals. If they
are covered with sulphate (whitish or greenish
deposit), remove and clean them.
The charging operation must be carried out in a well-ventilated area and away
from naked flames and any sources of sparks
so as to avoid the risk of explosion or fire.
Do not try to recharge a frozen battery: it
must first be thawed to avoid the risk of
explosion. If it has frozen, before charging it,
have the battery checked by a specialist who
will check that the interior components have
not been damaged and that the container is
not cracked, which would involve a risk of
leakage of toxic and corrosive acid.
Perform a slow charge at low amperage for
about 24 hours maximum to avoid damaging
the battery.
The presence of this label, in particular with the Stop & Start system, indicates
the use of a 12 V lead-acid battery with
special technology and specification; the
involvement of a CITROËN dealer or a
qualified workshop is essential when
replacing or disconnecting the battery.
After refitting the battery at a CITROËN dealer or a qualified workshop, the Stop
& Start system will only be active after a
continuous period of immobilisation of the
vehicle, a period which depends on the
climatic conditions and the state of charge of
the battery (up to about 8 hours).
