Under-inflation detection
The tyre under-inflation detection system
is a driving aid which does not replace the
need for vigilance on the part of the driver.This system does not relieve you of
the monthly check of the tyre inflation
pressures (including the spare) and before
a


long journey.
Driving with under-inflated tyres impairs
handling, extends braking distances and
causes premature tyre wear, particularly
in adverse conditions (heavy loads, high
speeds, long journeys).
Driving with under-inflated tyres
increases fuel consumption.
The tyre pressure specifications for your
vehicle can be found on the tyre pressure
label.
Tyre pressures should be checked when
the tyres are "cold" (vehicle stopped for
1 hour or after a journey of less than
6 miles (10 km) at moderate speeds).
Other wise, add 0.3 bar to the values
indicated on the label.
For more information on Identification
markings , including in particular the tyre
pressure label, refer to the corresponding
section. The tyre pressure measurement unit can be
configured with the MODE
button: in the "Tyre
pressure measurement" menu, select "psi/bar/
k Pa".
For more information on Vehicle
configuration , refer to the corresponding
section.
Under-inflation warning
This warning is indicated by
continuous illumination of this lamp,
an audible signal and, depending on
the equipment installed, a message
displayed on the screen.
System which automatically checks the
pressures of the tyres while driving.
The system continuously monitors the
pressures of the four tyres, as soon as the
vehicle is moving.
A pressure sensor is located in the valve of
each tyre (except the spare wheel).
The system triggers an alert as soon as it
detects a

drop in the inflation pressure of one
or more tyres. In the event of a
problem with one of the tyres,
depending on equipment the symbol or the
message appears to identify it.

Maintenance
Correct operation is only possible if the towball
and its carrier are kept clean.
Before cleaning the vehicle with a high-
pressure jet wash, the towball must be removed
and the protective plug fitted to the carrier.
Apply the label provided to a


clearly visible
area, close to the carrier or in the boot.
Go to a
CITROËN dealer or a qualified
workshop for any work on the towbar
system.
Roof carrying systems
F Remove the towball downwards from its carrier 1 .
F

R
elease the locking wheel; this
automatically stops in the unlocked position
(position B ).
F

R
efit the protective plug to the carrier.
F

C
arefully stow the towball in its bag away
from knocks and dirt. For reasons of safety and to avoid damaging
the roof, it is essential to use a
carrying system
(roof bars or roof rack) that is approved for your
vehicle.
Roof bars can only be fitted to a
van, combi
or minibus model of height H1
or H2. On
a
minibus, check for the presence of roof air
conditioning units.
The carrying system must always be secured to
the fitting points provided on the vehicle's roof:
6, 8
or 10, depending on the wheelbase of the
vehicle.
Obser ve the instructions for fitting and use
provided with the carrying system.

Checks
These operations allow your vehicle to be
kept in good working order. Ask for advice
from a CITROËN dealer or refer to the
manufacturer's service schedule included
in the handbook pack.
Battery
The battery does not require any
maintenance.
However, check regularly that the
terminals are correctly tightened
(models without quick release
terminals) and that the connections
are clean. Models equipped with Stop & Start are
fitted with a
12 V lead-acid battery of
specific technology and specification.
Its replacement should be carried out
only by a CITROËN dealer or a qualified
workshop.
Filter, air
At the start of winter, have your battery checked
by a CITROËN dealer or a qualified workshop.
For best quality cleaning and to prevent
freezing, this fluid must not be topped up or
replaced with plain water.
In wintry conditions, the use of an alcohol or
methanol based fluid is recommended.
Refer to the manufacturer's
ser vice schedule for details of
the replacement inter val for this
component.
Depending on the environment (e.g. dusty
atmosphere) and the use of the vehicle (e.g.
city driving), replace it twice as often if
necessary .
Filter, passenger
compartment
Refer to the manufacturer's
ser vice schedule for details of
the replacement inter val for this
component. Depending on the environment (e.g. dusty
atmosphere) and the use of the vehicle (e.g.
city driving), replace it twice as often if
necessary
.
Oil filter
Change the oil filter each time the
engine oil is changed.
Refer to the manufacturer's
ser vice schedule for details of
the replacement inter val for this
component.
Particle filter (Diesel)
A clogged passenger compartment
filter may have an adverse effect on
the per formance of the air conditioning
system and generate undesirable odours.
As an addition to the catalytic converter,
this filter makes an active contribution to the
preser vation of air quality by retaining unburnt
pollutant particles. Black exhaust fumes are
also eliminated.
