Emergency braking
If depressing the brake pedal fails to provide
effective braking or in exceptional circumstances
(e.g.
driver unwell, assisted driving), the vehicle
can be braked by sustained pulling on the
electric parking brake control. Braking continues
for as long as the control is kept pulled, and
ceases when the control is released.
The ABS and DSC systems stabilise the vehicle
during emergency braking.
If emergency braking malfunctions, the message
"Parking brake fault" will be displayed on the
instrument panel.
If the ABS and DSC systems
malfunction, indicated by lighting
one or both warning lamps on the instrument
panel, the vehicle’s stability is no longer ensured.

Practical information
7For domestic or accelerated charging
Before charging
Depending on the context:
►

Have a professional check that the
electrical system to be used complies with
applicable standards and is compatible with
the vehicle.
►


Have a professional electrician install
a dedicated domestic power socket or
accelerated charging unit (W

allbox)
compatible with the vehicle.
You should preferably use the charging cable
available as an accessory.
For more information, contact a CITROËN
dealer or a qualified workshop.
During charging
While charging is in progress, unlocking
the vehicle will cause the charging to stop.
If no action is taken on one of the openings
(door or boot) or on the charging nozzle, the
vehicle will lock again after 30 seconds and
charging will resume automatically.
Never work under the bonnet:
–

Some areas remain very hot, even an hour
after charging ends - risk of burns!
–


The fan may start at any time - risk of cuts
or strangulation!
After charging
Check that the charging flap is closed.
Do not leave the cable connected to the
domestic power socket - risk of short-circuit
or electrocution in the event of contact with or
immersion in water!
For superfast charging
Before charging
Check that the fast public charging
station and its charging cable are compatible
with the vehicle.
If the exterior temperature is below:
–

0°C, charging times may be extended.
–


-20°C, charging is still possible, but
charging times may be extended even further
(the battery has to be heated first).
After charging
Check that the charging flap is closed.
Connection
► Before charging, check that the drive selector
is in mode P, otherwise charging is not possible.
►

Open the charging flap by pressing the
push-button, and check that there are no foreign
bodies on the charging connector

.
Domestic charging, mode 2



► Connect the charging cable from the control
unit to the domestic socket.
When the connection is made, all of the indicator
lamps on the control unit light up, then only the
POWER
indicator lamp remains on in green.
►

Remove the protective cover from the
charging nozzle.
►


Insert the nozzle into the charging connector
.
The start of charging is confirmed by the flashing
green CHARGE indicator lamps in the flap, then
those on the control unit.
If this is not the case, charging has not
started; restart the procedure, ensuring that all
connections are properly established.
The red indicator lamp in the flap comes on to
indicate that the nozzle is locked.
When charging is complete and while the
charging cable is still connected, opening

Practical information
7Precautions for use
AdBlue® is a urea-based solution. This fluid is
non-flammable, colourless and odourless (when
kept in a cool place).
In the event of contact with the skin, wash the
affected area with soap and running water. In the
event of contact with the eyes, immediately rinse
the eyes with large amounts of water or with an
eye wash solution for at least 15 minutes. Seek
medical attention if you feel a persistent burning
sensation or irritation.
If swallowed, immediately wash out the mouth
with clean water and then drink plenty of water.
In certain conditions (high temperature, for
example), the risk of release of ammonia cannot
be excluded: do not inhale the fluid. Ammonia
vapours have an irritant effect on mucous
membranes (eyes, nose and throat).
Store AdBlue® out of the reach of
children, in its original container.
Procedure
Before starting the top-up procedure, ensure that
the vehicle is parked on a flat and level surface.
In wintry conditions, ensure that the temperature
of the vehicle is above -11°C. Otherwise the
AdBlue
® may be frozen and so cannot be poured
into the tank. Park the vehicle in a warmer area
for a few hours to allow the top-up to be carried
out.
Never pour the AdBlue® into the Diesel
fuel tank.
If any AdBlue® is splashed, or if there are
any spillages on the bodywork, rinse
immediately with cold water or wipe with a
damp cloth.
If the fluid has crystallised, clean it off using a
sponge and hot water.
Important: in the event of a top-up after
a breakdown because of a lack of
AdBlue, it is essential to wait around 5
minutes before switching on the ignition,
without opening the driver’s door,
unlocking the vehicle, inserting the key
into the ignition switch, or bringing the
key for the "Keyless Entry and Start"
system into the passenger compartment.
Switch on the ignition, then wait for 10
seconds before starting the engine.
►

Switch off the ignition and remove the key
from the switch to switch off the engine.
or
►


With Keyless Entry and Start, press the
"

START/STOP" button to switch off the engine.


► Turn the blue cap of the AdBlue® tank anti-
clockwise and remove it.
►

With a container of

AdBlue
®: after checking
the expiry date, read the instructions on the
label carefully before pouring the contents of the
container into the vehicle's AdBlue tank.
►

With an


AdBlue® pump: insert the nozzle and
fill the tank until the nozzle automatically cuts
out.
In order not to overfill the AdBlue® tank:
–
Add between 10 and 13 litres using
AdBlue® containers.
–
Stop after the nozzle’ s first automatic cut-
out, if you are refilling at a service station.
The system only registers AdBlue
® top-ups of
5

litres or more.
If the AdBlue® tank is completely empty
– which is confirmed by the message
"Top up

AdBlue: Starting impossible" – it is
essential to add at least 5 litres.

In the event of a breakdown

► Switch on the compressor by moving the
switch to position " I
" until the tyre pressure
reaches 2 bar. The sealant product is injected
under pressure into the tyre; do not disconnect
the pipe from the valve during this operation (risk
of blowback).
If after approximately 7 minutes, the
pressure of 2 bar is not reached, this
indicates that the tyre is not repairable;
contact a CITROËN dealer or a qualified
workshop for assistance.
►

Move the switch to position " O

".
►

Disconnect the compressor's electric plug
from the vehicle's 12

V socket.
►

Remove the kit.
►


Refit the cap on the valve.
►


Remove and store the bottle of sealant.
The sealant product is harmful if swallowed and causes irritation to the
eyes.
Keep this product out of the reach of children.
The use-by date of the fluid is marked on the
bottle.
After use, do not discard the bottle into the
environment; take it to a CITROËN dealer or
an authorised waste disposal site.
Do not forget to obtain a new bottle of
sealant, available from a CITROËN dealer or
a qualified workshop.


► Drive immediately for approximately 3 miles
(5 kilometres) at reduced speed (between
12 and 37 mph (20 and 60
km/h)) to plug the
puncture.
►

Stop to check the repair
and the tyre
pressure using the kit.
With a tyre repaired using this type of kit,
do not exceed a speed of 50
mph
(80

km/h) and do not drive more than
50

miles (80 km).
You must contact a CITROËN dealer or a
qualified workshop to have the repair checked
and the tyre changed.
Checking/adjusting tyre
pressures
The compressor can be used, without injecting
sealant, to check and, if necessary, adjust the
tyre pressures.
►

Remove the valve cap from the tyre and keep
it in a clean place.
►


Uncoil
the pipe stowed under the compressor.
►

Screw the pipe onto the valve and tighten
firmly

.
►

Check that the compressor switch is in
position " O

".
►

Fully uncoil the electric cable stowed under
the compressor

.
►

Connect the compressor's electric plug to the
vehicle's 12

V socket.
►

Switch the ignition on.
►


Start the compressor by placing the switch at
position " I

" and adjust the pressure to the value
shown on the vehicle's tyre pressure label. To
deflate: press the black button located on the
compressor pipe, near the valve connection.
If after 7 minutes the pressure of 2 bar is
not reached, the tyre is damaged;
contact a CITROËN dealer or a qualified
workshop for assistance.
►

Once the correct pressure is reached, put the
switch in position " O

".
►

Remove the kit and stow it.
►


Refit the cap on the valve.
