127
Practical information
7– 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.
Selecting the mode
A confirmation message is displayed when
energy economy mode is entered, and the active
functions are placed on standby.
If a telephone call is in progress at the
time, it will be maintained for around 10
minutes via the audio system’s hands-free
system.
Exiting the mode
These functions are automatically reactivated the
next time the vehicle is used.
To restore the use of these functions
immediately, start the engine and let it run:
–

For less than 10 minutes, to use the
equipment for approximately 5 minutes.
–


For more than 10 minutes, to use the
equipment for approximately 30 minutes.
Let the engine run for the specified duration to
ensure that the battery charge is sufficient.
T

o recharge the battery, avoid repeatedly or
continuously restarting the engine.
A flat battery prevents the engine from starting.
For more information on the 12
V battery,
refer to the corresponding section.
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.
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.

Practical information
further 1,500 miles (2,400 km) before the tank is
empty and the vehicle is immobilised.
If the estimated distance travelled by the
vehicle between two services is greater than
12,500
miles (20,000 km), it will be necessary to
top up the AdBlue.
For more information on the Warning
and indicator lamps and the associated
alerts, or the Indicators, please refer to the
corresponding sections.
Once the AdBlue® tank is empty, a device
required by law prevents the engine from
being restarted.
If the SCR system is faulty, the level of
emissions from the vehicle will no longer meet
the Euro 6 standard and the vehicle starts
polluting the environment.
In the event of a confirmed SCR system
malfunction, it is essential to visit a CITROËN
dealer or a qualified workshop. After 685
miles (1,100 km), a device is automatically
activated to prevent the engine from starting.
In both cases, a range indicator indicates
the distance that can be travelled before the
vehicle is stopped.
Freezing of the AdBlue®
AdBlue® freezes at temperatures below
around -11°C.
The SCR system includes a heater for the
AdBlue® tank, allowing you to continue driving
in very cold conditions.
Supply of AdBlue®
It is recommended that the AdBlue® be topped
up as soon as the first alert is issued indicating
that the reserve level has been reached.
For the correct operation of the SCR
system:
–

Use
only AdBlue
® fluid that meets the ISO
22241 standard.
–

Never

transfer AdBlue
® to another container
as it would lose its purity.
–

Never dilute

AdBlue
® with water.
You can obtain AdBlue
® from a CITROËN dealer
or a qualified workshop, as well as service
stations equipped with AdBlue
® pumps specially
designed for passenger vehicles.
Never top up from an AdBlue® dispenser
reserved for heavy goods vehicles.
Recommendations on storage
AdBlue® freezes at about -11°C and deteriorates
above +25°C. Containers should be stored in a
cool area and protected from direct sunlight.
Under these conditions, the fluid can be kept for
at least a year.
If the fluid has frozen, it can be used once it has
completely thawed out at room temperature.
Never store AdBlue® containers in your
vehicle.
Precautions 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.

Starting using another
battery
If the vehicle's battery is flat, the engine can be
started using a backup battery (either external or
from another vehicle) and jump leads or using a
battery booster.
Never start the engine by connecting a
battery charger.
Never use a 24
V or higher battery booster.
Check beforehand that the backup battery
has a nominal voltage of 12
V and a capacity
at least equal to that of the discharged
battery.
The two vehicles must not be in contact with
each other.
Switch off all electricity-consuming equipment
on both vehicles (audio system, wipers,
lighting, etc.).
Make sure that the jump leads are well away
from the engine’s moving parts (fan, belt,
etc.).
Do not disconnect the (+) terminal while the
engine is running.

minutes, with the vehicle stationary, so that
the battery reaches an adequate state of charge.
Driving immediately without having
reached a sufficient level of charge may
affect some of the vehicle's functions.
Automatic gearbox
Never try to start the engine by pushing
the vehicle.
Charging the battery using a
battery charger
For optimum service life of the battery, it is
essential to maintain an adequate state of
charge.
In some circumstances, it may be necessary to
charge the battery:
–

When using the vehicle mainly for short
journeys.
–


If the vehicle is to be taken off the road for
several weeks.
Contact a CITROËN dealer or a qualified
workshop.
To charge the vehicle's battery yourself, use only a charger compatible with
lead-acid batteries with a nominal voltage of
12

V.
