Charging is managed by the smartphone.
For versions with Keyless Entry and Starting,
operation of the charger may be interrupted
when opening a door or switching off the
ignition.
Charging
F With the charging area clear, place a device
at its centre.
The system only supports charging one
portable device at a


time.
Once the portable device is detected, the
charge indicator lamp comes on in green. It
stays lit for the whole time that the battery is
being charged. Do not leave any metal objects (coins,
keys, vehicle remote control, etc.) in
the charging area while a
device is
being charged – risk of overheating or
interrupting the charging process!Checking operation

Emergency braking assistance
(EBA)
In an emergency, this system enables you to
reach the optimum braking pressure more
quickly and therefore reduce the stopping
distance.
It is triggered in relation to the speed at which
the brake pedal is pressed. This is felt by
a reduction in the resistance of the pedal and
an increase in braking efficiency.
Anti-slip regulation (ASR)
This system optimises traction in order to
avoid wheel slip by acting on the brakes of
the driving wheels and on the engine. It also
improves the directional stability of the vehicle
on acceleration.
Dynamic stability control (DSC)
If there is a difference between the path
f ollowed by the vehicle and that required by the
driver, this system monitors each wheel and
automatically acts on the brake of one or more
wheels and on the engine to return the vehicle
to the required path, within the limits of the laws
of physics.
Trailer stability assist (TSA)
This system allows control of the vehicle to be
retained when towing a trailer, so as to avoid
the risk of snaking.
Anti-lock braking system
(ABS) and electronic brake
force distribution (EBFD)
The fixed illumination of this warning
lamp signals that there is a fault with
the ABS.
Illumination of this warning lamp,
coupled with the STOP and ABS
warning lamps, accompanied by the
display of a
message and an audible
signal, signals that there is a
fault
with the electronic brake force
distribution (EBFD). Normal operation of the ABS may make
itself felt by slight vibrations of the brake
pedal.
When braking in an emergency, press
very firmly and maintain this pressure.
When changing wheels (tyres and rims),
ensure that these are approved for your
vehicle.
After an impact, have these systems
checked by a
CITROËN dealer or
a


qualified workshop.
Intelligent traction control
system ("Snow motion ")
The vehicle retains conventional braking. Drive
carefully at moderate speed.
Contact a
CITROËN dealer or a qualified
workshop as soon as possible.
You must stop as soon as it is safe to do so.
Call a
CITROËN dealer or a qualified
workshop. Depending on version, your vehicle has
a
system to help driving on snow: intelligent
traction control.
This system detects situations of poor sur face
grip that could make it difficult to move off
or make progress on deep fresh snow or
compacted snow.
In these situations, the intelligent traction
control limits the amount of wheel spin to
provide the best traction and trajectory control
for your vehicle.
Safety

94
ASR/DSC
These systems offer increased safety
in normal driving, but they should not
encourage the driver to take extra risks or
drive at high speed.
It is in conditions of reduced grip (rain,
snow, ice) that the risk of loss of grip
increases. It is therefore important for your
safety to keep these systems activated in
all conditions, and particularly in difficult
conditions.
The correct operation of these
systems depends on obser vation of
the manufacturer's recommendations
regarding both the wheels (tyres and
rims), braking and electronic components
and the assembly and repair procedures
used by CITROËN dealers.
The use of snow tyres is recommended,
in order to be able to benefit from the
efficiency of these systems in winter
conditions.
In this case, it is essential to equip the
four wheels with tyres approved for your
vehicle.Trailer stability assist (TSA)
When towing, this system reduces the risk of
the vehicle or trailer swaying.
Operation
The system is activated automatically when the
ignition is switched on.
The electronic stability control (ESC) must not
have any faults.
If the system detects oscillations (snaking) in
the movement of the trailer at speeds between
37 and 99 mph (60 and 160 km/h), it acts
on the brakes to stabilise the trailer and, if
necessary, reduces the engine power to slow
down the vehicle.
The correction is signalled by the
flashing of this warning lamp in the
instrument panel and illumination of
the brake lamps.
For information on the weights and towed
loads, refer to the "Technical data" section or
the registration certificate for your vehicle.
To ensure complete safety while driving with
a
To w b a r d e v i c e , refer to the corresponding
section.
Operating fault
Should a fault occur with the system,
t his warning lamp comes on in the
instrument panel, accompanied by
the display of a
message and an
audible signal.
The trailer stability assist system offers
increased safety in normal driving,
provided that the recommendations on
towing a
trailer are obser ved. It should not
encourage the driver to take risks, such
as towing a
trailer in adverse operating
conditions (overloading, failure to obser ve
the trailer nose weight, worn or under-
inflated tyres, faulty braking system, etc.)
or drive at too high a
speed.
In certain cases, snaking of the trailer
may not be detected by the ESC system,
particularly with a


light trailer.
When driving on slippery or poor sur faces,
the system may not be able to prevent
sudden snaking of the trailer.
If you continue to tow a
trailer, reduce your
speed and drive carefully!
Contact a
CITROËN dealer or a qualified
workshop to have the system checked.
Safety

In case of towing
Driving with a trailer places greater
d emands on the towing vehicle and
requires extra care from the driver.
Respect the maximum towable weights.
At altitude: reduce the maximum load
by 10% per 1,000
metres of altitude; the
decreased air density at altitude reduces
engine performance.
New vehicle: do not pull a
trailer
before having 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
On leaving the flooded road, as soon as safety
conditions allow, make several light brake
applications to dry the brake discs and pads.
If in doubt about the state of your vehicle,
contact a
CITROËN dealer or a qualified
workshop.
F

D
istribute 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.
Ty r e s
F Check the tyre pressures of the towing vehicle and of the trailer, observing the
recommended pressures.
Lighting
F 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 increases the
t emperature of the coolant. The maximum
towable load depends on the gradient and the
exterior temperature. The cooling capacity of
the fan does not increase with engine speed.

R
educe speed and lower the engine speed,
so as to limit the heating-up.
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 of the brakes, the
use of engine braking is recommended.
Side wind
Bear in mind the increased susceptibility to the
wind that the vehicle will have.
