Maximum load, distributed over the roof
bars, for a loading height not exceeding
40
cm: 80 kg.
As this value may be changed, please
verify the maximum load quoted in the
user guide supplied with the roof bars.
If the height exceeds 40
cm, adapt the
speed of the vehicle to the profile of the
road to avoid damaging the roof bars and
the fixings on the vehicle.
Be sure to refer to national legislation in
order to comply with the regulations for
transporting objects which are longer than
the vehicle.
When carrying long objects, it is
recommended that the motorised tailgate
function is deactivated.
Very cold climate screen(s)
(Depending on the country where the product
is sold.)
Removable screen(s) which prevent snow
accumulating at the radiator cooling fan.
Depending on the version, you have one or two
screens. Before fitting or removing a
screen,
ensure that the engine is off and the
cooling fan has stopped.
Fitting Removing
F Use a
screwdriver as a lever to release each
of the fixings of each screen in turn.
It is essential to remove the very cold
climate screen (or screens):
-

hen the exterior temperature exceeds
10°C,
-
w

hen towing,
-

a

The pre-cut section must be removed
before fitting the screen on the front
bumper, in order to be able to release the

present, the camera image is slightly
altered.

Practical information

204
Only use products recommended by
CITROËN or products of equivalent quality
and specification.
In order to optimise the operation of
components as important as those in the
braking system, CITROËN selects and
offers very specific products.
After washing the vehicle, dampness, or
in wintry conditions, ice can form on the
brake discs and pads: braking efficiency
may be reduced. Make light brake
applications to dry and defrost the brakes.
AdBlue® (BlueHDi engines)
To respect the environment and ensure
compliance with the Euro 6 standard, without
adversely affecting the per formance or fuel
consumption of Diesel engines, CITROËN
has taken the decision to equip its vehicles
with a
system that associates SCR (Selective
Catalytic Reduction) with a
Diesel particle filter
(DPF) for the treatment of exhaust gases.
SCR system
Using a fluid called AdBlue® that contains
urea, a catalytic converter turns up to 85%
of nitrogen oxides (NOx) into nitrogen and
water, which are harmless to health and the
environment.
The AdBlue
® is contained in
a
special tank holding about
17


litres.
Its capacity allows a

driving range of around
12,500

miles (20,000

km). An alert system is
triggered automatically once the reser ve level
is reached: you can then drive for a
further
1,500

miles (2,400

km) before the tank is
e m pt y. Once the AdBlue
® tank is empty, a system
required by regulations prevents starting
of the engine.
If the SCR system is defective, the level of
emissions from your vehicle will no longer
meet the Euro 6

standard: your vehicle
becomes polluting.
In the event of a

confirmed fault with the
SCR system, you must go to a
CITROËN
dealer or a

qualified workshop as soon
as possible: after a
running distance of
685

miles (1,100

km), a system will be
triggered automatically to prevent engine
starting.
In either case, a range indicator gives you
the distance you can travel before the
vehicle is immobilised.
For more information on the Warning and
indicator lamps and associated alerts,
refer to the corresponding section.
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.
Practical information

205
Topping up the AdBlue®
Filling the AdBlue® tank is an operation
included in every routine ser vice on your
vehicle by a

CITROËN dealer or a qualified
workshop.
Nevertheless, given the capacity of the tank, it
may be necessary to top up the fluid between
services, more particularly if an alert (warning
lamps and a


message) signals the requirement.
You can go to a

CITROËN dealer or a qualified
workshop.
If you envisage topping up yourself, please
read the following warnings carefully.
Supply of AdBlue®
It is recommended that the AdBlue® is
topped up as soon as the first alert is
issued indicating that the reser ve level has
been reached.
In order to ensure that the SCR system
operates correctly:
-

U

se only AdBlue
® liquid that meets the
ISO
22241
standard.
-

N

ever transfer AdBlue
® to another
container: it would lose its purity.
-

N

ever dilute AdBlue
® with water. You can obtain AdBlue
® from a CITROËN
d
ealer or a

qualified workshop.
You can also visit a
petrol station
equipped with AdBlue
® pumps specially
designed for passenger vehicles (for those
versions with access to the AdBlue
® tank
via the fuel filler flap).
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. It should be stored in
a

cool place and protected from direct sunlight.
Under these conditions, the fluid can be kept
for at least a
year.
If the additive has frozen, it can be used once it
has completely thawed out.
Never keep containers or bottles of
AdBlue
® in your vehicle.
Precautions for use
AdBlue® is a urea-based solution. This liquid
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 water. In the event
of contact with the eyes, wash (irrigate) the
eyes with large amounts of water or with an eye
wash solution for at least 15
minutes. If you feel
a

persistent burning sensation or irritation, get
medical attention.
If swallowed, immediately wash out the mouth
with clean water and then drink plenty of water.
In certain conditions (at high temperature,
for example), the risk of release of ammonia
cannot be excluded: do not inhale the vapour.
Ammonia has an irritant effect on mucous
membranes (eyes, nose and throat).
Keep AdBlue
® out of the reach of children,
in its original container or bottle.
Procedure
Before starting the top-up procedure, ensure
that the vehicle is parked on a flat and level
sur face.

Changing a bulb
The lamps have polycarbonate lenses with
a
protective coating:
F

d
o not clean them using a dr y or
abrasive cloth, nor with a
detergent
or solvent product,
F

u
se a sponge and soapy water or a pH
neutral product,
F

w
hen using a high pressure washer
on persistent marks, do not keep the
lance directed towards the lamps or
their edges for too long, so as not to
damage their protective coating and
seals.
Changing a
bulb should only be done after
the lamp has been switched off for several
minutes (risk of serious burns).
F

D
o not touch the bulb directly with your
fingers, use a
lint-free cloth.
It is essential only to use anti-ultraviolet
(UV) type bulbs, so as not to damage the
headlamp.
Always replace a
failed bulb with a new
bulb with the same type and specification. In some weather conditions (e.g. low
temperature or humidity), the presence
of misting on the internal sur face of the
glass of the headlamps and rear lamps is
normal; it disappears after the lamps have
been on for a
few minutes.
Risk of electrocution
Xenon bulbs (D5S-25W) must be replaced
by a
CITROËN dealer or a qualified
workshop.
