Engine light CITROEN C4 PICASSO 2022 Owner's Manual

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

12 V battery
General points
Lead-acid starter batteries
Batteries contain harmful substances
such as sulphuric acid and lead.
They must be disposed of in
accordance with regulations and must
not, in any circumstances, be discarded
with household waste.
Take used remote control batteries and
vehicle batteries to a
special collection
point.
Protect your eyes and face before
handling the battery.
All operations on the battery must be
carried out in a
well ventilated area and
away from naked flames and sources of
sparks, so as to avoid the risk of explosion
or fire.
Wash your hands afterwards.
Access to the battery
The battery (-) terminal is not accessible.
A remote earth point is located on the upper
part of the bonnet (next to the battery).
Starting using another
battery
When your vehicle's battery is discharged, the
engine can be started using a backup battery
(external or from another vehicle) and jump
leads or a
battery booster.
Never try to start the engine by connecting
a
battery charger.
Never use a
24 V or higher battery
b o o s t e r.
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 the electrical consumers on
both vehicles (audio system, wipers,
lighting, etc.).
Ensure that the jump lead cables do not
pass close to moving parts of the engine
(cooling fan, belts, etc.).
Do not disconnect the (+) terminal while
the engine is running.
The battery is located under the bonnet.
For access to the (+) terminal:
F

r

elease the bonnet using the interior lever,
then the exterior safety catch,
F

r

aise the bonnet and secure it with its stay,
F

l

ift the plastic cover for access to the (+)
terminal.

233
Disconnecting the battery
In order to maintain an adequate state
of charge for starting the engine, it is
recommended that the battery be disconnected
if the vehicle is taken out of ser vice for a long
period.
Quick-release terminal clamp
F Switch off the ignition.
F S witch off all electrical consumers (audio
system, lighting, wipers, etc.).
F

S
witch off charger B before connecting the
cables to the battery, so as to avoid any
dangerous sparks.
F

E
nsure that the charger cables are in good
condition.
F

R
aise the plastic cover, if your vehicle has
one, on the (+) terminal.
F

C
onnect charger B cables as follows:
-

t
he (+) red cable to the (+) terminal of
battery A ,
-

t
he (-) black cable to earth point C on the
vehicle. Never try to charge a
frozen battery – risk
of explosion!
If the battery has frozen, have it checked
by a
CITROËN dealer or by a qualified
workshop who will check that the internal
components have not been damaged and
that the container has not cracked, which
would mean a
risk of toxic and corrosive
acid leaking.
F

A
t the end of the charging operation, switch
off charger B before disconnecting the
cables from battery A .
If this label is present, it is essential to
use only a 12 V charger to avoid causing
irreversible damage to the electrical
components related to the Stop & Start
system. Before disconnecting the battery:
F
c
lose all openings (doors, boot, windows,
roof),
F
s
witch off all electrical consumers (audio
system, wipers, lighting, etc.).
F
s
witch off the ignition and wait for four
minutes.
At the battery, detach the (+) terminal only.
Disconnecting the (+) terminal
F

Ra
ise the lever A fully to release the clamp B .
F

R
emove the clamp B by lifting it off.

Engine technical data and
towed loads
Engines
The engine characteristics are given in the
vehicle's registration document, as well as in
sales brochures.The maximum power corresponds to the
value type-approved on a
test bed, under
conditions defined in European legislation
(Directive 1999/99/EC).
For more information, contact a
CITROËN
dealer or a
qualified workshop.
Weights and towed loads
The weights and towed loads relating to your
vehicle are given in the registration document,
as well as in sales brochures.
These values are also given on the
manufacturer's plate or label.
For more information, contact a CITROËN
dealer or a
qualified workshop. The GTW (Gross Train Weight) and towed load
values indicated are valid up to a
maximum
altitude of 1,000 metres. The towed load value
must be reduced by 10% for each additional
1,000 metres of altitude.
The maximum authorised nose weight
corresponds to the weight permitted on the
towball.
When exterior temperatures are high,
the vehicle per formance may be limited
in order to protect the engine. When the
exterior temperature is higher than 37°C,
limit the towed weight.
Towing using a lightly loaded vehicle can
adversely affect roadholding.
Braking distances are increased when
towing a trailer.
When using a vehicle to tow, never
exceed a speed of approximately 60 mph
(100
km/h) (obser ve the local legislation
in force).
If the exterior temperature is high, it is
recommended that the engine is allowed
to idle for 1
to 2 minutes after the vehicle
comes to a
stop, to facilitate its cooling.
