protective plug fitted to the carrier.
Work on the towing device
Contact a CITROËN dealer or a qualified
workshop.
Towing device
Load distribution
► Distribute the load in the trailer so that the
heaviest items are as close as possible to the
axle, and the nose weight approaches the
maximum permitted without exceeding it.
Air density decreases with altitude, thus reducing
engine performance. The maximum towable load
must be reduced by 10% per 1,000
metres of
altitude.
Use genuine towing devices and wiring
harnesses approved by CITROËN. We
recommend having them fitted by a CITROËN
dealer or a qualified workshop.
If not fitted by a CITROËN dealer, they must
still be fitted in accordance with the vehicle
manufacturer's instructions.
Certain driving or manoeuvring aid functions
are automatically deactivated while an
approved towing system is in use.
For more information about driving with a
towing device fitted to a trailer and associated
with the Trailer stability assist, refer to the
corresponding section.
Comply with the maximum authorised
towable weight, as indicated on your
vehicle's registration certificate, on the
manufacturer's label and in the Technical
data section of this guide.
If using accessories attached to the
towing device (e.g. bicycle carriers, tow
boxes):
–

Comply with the maximum authorised nose
weight.
– Do not transport more than 4 conventional
bicycles or 2 electric bicycles.
When loading bicycles onto a bicycle carrier
on a towball, be sure to place the heaviest
bicycles as close as possible to the vehicle.
Observe the legislation in force in the
country where you are driving.
Load reduction mode
This system manages the use of certain
functions according to the level of charge
remaining in the battery.
When the vehicle is being driven, the load
reduction function temporarily deactivates certain
functions, such as the air conditioning and the
heated rear screen.
The deactivated functions are reactivated
automatically as soon as conditions permit.
Energy economy mode
This system manages the duration of use of
certain functions, in order to conserve a sufficient
level of charge in the battery with the ignition off.
After switching off the engine and for a maximum
cumulative period of around 30 minutes, you can
continue to use functions such as the audio and
telematics system, dipped beam headlamps or
courtesy lamps.

Practical information
7for 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.


► With the vehicle unlocked and the fuel filler
flap open, turn the blue cap of the AdBlue® tank
a quarter turn anti-clockwise.
Filling up
► 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.
After refilling
► Perform the same sequence of operations in
reverse order .
Do not dispose of AdBlue® containers in
the household waste.
Place them in a container reserved for this
purpose or take them back to where you
purchased them.
