Under-inflation detection
The under-inflation detection system d
oes not replace the need for vigilance
o
n the part of the driver.
This
system does not avoid the need to
c
heck the tyre pressures (including the
s
pare wheel) every month as well as
b
efore a long journey.
Driving
with under-inflated tyres impairs
r
oad holding, extends braking distances
a
nd causes premature tyre wear,
p
articularly under arduous condition
(
high loading, high speed, long journey).The
inflation pressures defined for y
our vehicle can be found on the tyre
p
ressure label.
For
more information on the
i
dentification markings, refer to the
c
orresponding
s
ection.
Tyre
pressures should be checked
w
hen the tyres are "cold" (vehicle
s
topped for 1 hour or after a journey of
l
ess than 6 miles (10 km) at moderate
s
peeds).
Other wise
(when hot), add 0.3 bar to
t
he pressures shown on the label.
Driving
with under-inflated tyres
i
ncreases fuel consumption.
System
which
automatically
checks
the
pressures
of
the
tyres while driving.
The
system
monitors
the
pressures
in
the
four
t
yres,
once
the
vehicle
is
moving.
It
compares
the
information
given
by
the
four
w
heel
speed
sensors
with
reference values,
which must be reinitialised ever y time the
tyre pressures are adjusted or a wheel
changed .
The
system
triggers
an
alert
as
soon
as
it
d
etects
a
drop
in
the
inflation
pressure
of
one
o
r
more
tyres.

AdBlue® additive and SCR system
f
or
BlueHDi Diesel engines
To assure respect for the environment and c
onformity with the new Euro 6 emissions
s
tandard, without adversely affecting the
p
er formance or fuel consumption of Diesel
e
ngines, CITROËN has taken the decision to
e
quip its vehicles with an effective system that
a
ssociates SCR (Selective Catalytic Reduction)
w
ith a particle filter (FAP) for the treatment of
e
xhaust gases.
Presentation of the SCR system
Using an additive called AdBlue® containing u
rea,
a
catalytic
converter
turns
up to 85%
o
f
nitrous
oxides
(NOx)
into
nitrogen and
w
ater,
which
are
harmless
to
health and the
e
nvironment. The
AdBlue
® additive is held in a special t
ank
located
under the boot at the rear of
t
he
vehicle.
It has a capacity of 17 litres: this
p
rovides
a
driving range of about 12 500 miles
(
20
000
km),
after which an alert is triggered
w
arning
you
when the reserve remaining is
e
nough
for
just 1 500 miles (2 400 km).
During
each
scheduled service of your vehicle
b
y
a
CITROËN dealer or a qualified workshop,
t
he
AdBlue
® additive tank is refilled in order to a
llow
normal operation of the SCR system.
If
the
estimated mileage between two services
i
s
greater
than 12 500 miles (20 000 km), we
r
ecommend
that you go to a CITROËN dealer
o
r
a
qualified workshop to have the necessary
t
op-up
carried out. Once
the AdBlue
® tank is empty, a s
ystem
required
by regulations prevents
s
tarting
of
the
engine.
If the SCR
is faulty, the level of
emissions
from
your vehicle will no
l
onger
meet
the
Euro 6 standard: your
v
ehicle
becomes
polluting.
In
the
event
of
a
confirmed fault
w
ith
the
SCR
system, you must go
t
o
a
CITROËN
dealer or a qualified
w
orkshop
as
soon as possible: after
a
running
distance of 650 miles
(
1 100
km),
a
system will be triggered
a
utomatically
to
prevent engine starting.
