2017 CITROEN C4 PICASSO brake

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.

Removing a wheel
* position P for the automatic gearbox
Parking the vehicle
Stop the vehicle where it does not block
traffic: the ground must be level, stable
and non-slippery.
Apply the parking brake, unless it is
programmed in automatic mode; switch
off the ignition and put the vehicle into first
gear* so as to block the wheels.
Check that the braking warning lamp and
the P warning lamp in the parking brake
control lever come on.
For more safety, position the
chock
2 against the wheel opposite the one you
are replacing.
Make absolutely certain that all the
occupants have left the vehicle and are
waiting in a safe area.
Never go underneath a vehicle raised
using a jack; use an axle stand.
Do not use:
-
t
he jack for any other purpose than
lifting the vehicle,
-
a j
ack other than the one supplied by
the manufacturer.
List of operationsF Place the foot of the jack 3 on the ground
and ensure that it is directly below the front
A or rear B jacking point provided on the
underbody, whichever is closest to the
wheel to be changed.
Ensure that the jack is stable. If the
ground is slippery or loose, the jack may
slip or collapse – Risk of injury!
Ensure that the jack is positioned only at
one of the jacking points A or B under the
vehicle, making sure that the vehicle's
contact sur face is centred on the head of
the jack. Otherwise, the vehicle could be
damaged and/or the jack could collapse –
Risk of injury!

Fitting the "space-saver " spare wheel
If your vehicle is fitted with alloy wheels,
when tightening the bolts on fitting, it is
normal to notice that the washers do not
come into contact with the "space-saver"
spare wheel. The wheel is secured by the
conical contact of each bolt.
After changing a wheel
With a "space-saver " type spare wheel
Visit a CITROËN dealer or a qualified
workshop as soon as possible to have the
tightness of the bolts and the pressure of
the spare wheel checked.
Have the punctured tyre examined. After
inspection, the technician will advise you
on whether the tyre can be repaired or if it
must be replaced. The tyre inflation pressures are given on
this label.
