Under-inflation detection
The system monitors the pressures in the four
tyres,
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
or
more tyres. The under-inflation detection system
does
not replace the need for vigilance
o
n the part of the driver.
This system does not avoid the need to
check
the tyre pressures (including the
s
pare wheel) every month as well as
before
a long journey.
Driving
with under-inflated tyres impairs
r
oad holding, extends braking distances
a
nd causes premature tyre wear,
particularly under arduous conditions
(high
loading, high speed, long journey).
System
which automatically checks the pressures of the tyres while driving.
The inflation pressures defined for
your vehicle can be found on the tyre
pressure
label.
For more information on the
Identification markings , refer to the
corresponding
s
ection.
Tyre
pressures should be checked
w
hen the tyres are "cold" (vehicle
stopped
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.

Fuel used for petrol engines
The petrol engines are compatible with E10 bio-petrol (containing 10 % ethanol),
c
onforming to European standards EN 228 and
E
N
1
5376.
E85
type fuels (containing up to 85 % ethanol)
a
re reserved exclusively for vehicles marketed
f
or the use of this type of fuel (BioFlex
v
ehicles). The quality of the ethanol must
c
omply with European standard EN 15293.
Fuel used for Diesel
engines
The Diesel engines are compatible with biofuels available at the pumps which meet
current
and future European standards:
-
D
iesel fuel that meets standard EN 590
mixed
with a biofuel that meets standard
E
N 14214,
-
D
iesel fuel that meets standard EN16734
m
ixed with a biofuel that meets standard
E
N14214 (possibly containing up to 10 %
F
atty Acid Methyl Ester),
-
P
araffinic Diesel fuel that meets standard
EN15940
mixed with a biofuel that meets
s
tandard EN14214 (possibly containing up
t
o 7 % Fatty Acid Methyl Ester).The
use of B20 or B30 fuel meeting standard E
N16709 is possible in your Diesel engines.
H
owever, this use, even occasional, requires
strict
application of the special servicing
c
onditions referred to as "Arduous conditions".
F
or more information, contact a CITROËN
dealer
or a qualified workshop.
The use of any other type of (bio)fuel
(vegetable
or animal oils, pure or diluted,
d
omestic fuel...) is strictly prohibited (risk of
d
amage to the engine and fuel system).
Only the use of Diesel fuel additives that meet
the
standard B715000 is authorised.
