Fatigue detection system
As soon as the speed of the vehicle
drops below 40 mph (65 km/h), the
system goes into standby.
The driving time is counted again once
the speed is above 40 mph (65 km/h).
It is recommended that you take a break as soon as you feel tired or at least every two hours.
The system cannot in any
circumstances replace the need for
vigilance on the part of the driver.
Do not take the wheel if you are tired.
Driving time warning
The system triggers an alert once it detects that
the driver has not taken a break after two hours
of driving at a speed above 40 mph (65 km/h).
This alert takes the form of the display of a
message encouraging you to take a break,
accompanied by an audible signal.
If the driver does not follow this advice, the
alert is repeated hourly until the vehicle is
stopped. The system resets itself if one of the following
conditions is met:
-

e
ngine running, the vehicle has been
stationary for more than 15 minutes,
-

t
he ignition has been switched off for a
few
m

inutes,
-

t
he driver's seat belt is unfastened and
their door is open.
Activation / Deactivation
The system is activated or deactivated via the
vehicle configuration menu.
For more information on the menu, refer to the
part covering your screen in the "Dashboard
instruments" section.
The state of the system stays in memory when
the ignition is switched off.

Driving with under-inflated tyres
increases fuel consumption.The under-inflation detection system
does not replace the need for vigilance
on the part of the driver.
This system does not avoid the need to
check the tyre pressures (including the
spare wheel) every month as well as
before a long journey.
Driving with under-inflated tyres impairs
road holding, extends braking distances
and causes premature tyre wear,
particularly under arduous conditions
(high loading, high speed, long journey).
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 section.
Snow chains
The system does not have to be
reinitialised after fitting or removing
snow chains.
Under-inflation detection
System which automatically checks the pressures of the tyres while driving.
The system monitors the pressures in the four
tyres, once the vehicle is moving.
It compares the information given by the four
wheel 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
detects a drop in the inflation pressure of one
or more tyres. Checking tyre pressures
This check should be done 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 pressures
shown on the label.

Fuel tank
Capacity of the tank:
- Pe trol: approximately 45 litres.
-

D
iesel: approximately 42 or 50 litres (depending on version).
Low fuel level Refuelling
When the low fuel level is reached,
this warning lamp in the instrument
panel comes on, accompanied by
an audible warning, a message and
the last bar of the fuel gauge flashes
in red.
To refuel in complete safety:
F

Y
ou must switch off the engine.
F

O
pen the filler flap.
A label on the inside of the fuel filler flap
reminds you of the type of fuel to use,
depending on your engine type.
Additions of fuel must be of at least 5 litres to
be registered by the fuel gauge.
When it first comes on, about 5 litres of fuel
remain in the tank.
Until sufficient fuel has been added, this
warning lamp appears every time the ignition
is switched on, accompanied by an audible
warning and a message. This audible warning
and message are repeated with increasing
frequency as the fuel level drops towards " 0".
Refuel as soon as possible to avoid running
out. Opening the filler cap may result in an inrush of
air. This is entirely normal and results from the
sealing of the fuel system.
If your vehicle is fitted with Stop & Start,
never refuel with the engine in STOP
mode; you must switch off the ignition
using the key, or the START/STOP
button if your vehicle has Keyless Entry
and Starting.

Snow chains
In wintry conditions, snow chains improve traction as well as the behaviour of the vehicle when braking.Use only the chains designed to be fitted to the
type of wheel fitted to your vehicle:
Original tyre size Type of chain
185/65 R15 Link of 9 mm maximum
195/65 R15
205/55 R16 205/50 R17
Cannot be fitted with chains
For more information on snow chains, contact a
CITROËN dealer or a qualified workshop.
Advice on installation
F If you have to fit the chains during a journey, stop the vehicle on a flat sur face
on the side of the road.
F

A
pply the parking brake and position any
wheel chocks to prevent movement of your
vehicle.
F

F
it the chains following the instructions
provided by the manufacturer.
F

M
ove off gently and drive for a few
moments, without exceeding 30 mph
(50
km/h).
F

S
top your vehicle and check that the snow
chains are correctly tightened.
Take account of the legislation in force
in your country on the use of snow
chains and the maximum running speed
authorised.
The snow chains must be fitted only
to the front wheels. They must never
be fitted to "space-saver" type spare
wheels.
Avoid driving with snow chains on roads
that have been cleared of snow, to
avoid damaging your vehicle's tyres and
the road sur face. If your vehicle is fitted
with alloy wheels, check that no part of
the chain or its fixings is in contact with
the wheel rim.
It is strongly recommended that before
you leave, you practise fitting the snow
chains on a level and dry sur face.

Checking components
12 V battery
The battery does not require any maintenance.
However, check regularly that the terminals
are correctly tightened (versions without quick
release terminals) and that the connections
are clean.Refer to the manufacturer's
service schedule for details of the
replacement intervals for these
components.
Air filter and passenger compartment filter
Replace the oil filter each time the
engine oil is changed.
Refer to the manufacturer's
service schedule for details of
the replacement interval for this
component.
Oil filter
Unless other wise indicated, check these components in accordance with the manufacturer's service schedule and according to your engine.
Other wise, have them checked by a CITROËN dealer or a qualified workshop.Depending on the environment (e.g. dusty
atmosphere) and the use of the vehicle (e.g.
city driving), replace them twice as often if
necessary.
A clogged passenger compartment filter may
have an adverse effect on the per formance
of the air conditioning system and generate
undesirable odours.
Particle filter (Diesel)
The start of saturation of the particle
filter is indicated by the fixed
illumination of this warning lamp
accompanied by a warning message.
As soon as the traffic conditions permit,
regenerate the filter by driving at a speed of at
least 40 mph (60 km/h) until the warning lamp
goes off.
If the warning lamp stays on, this indicates a
low additive level.
For more information on Checking levels and
the Diesel additive level in particular, refer to
the corresponding section.
On a new vehicle, the first particle
filter regeneration operations may be
accompanied by a "burning" smell,
which is per fectly normal.
Following prolonged operation of the
vehicle at very low speed or at idle,
you may, in exceptional circumstances,
notice the emission of water vapour at
the exhaust on acceleration. This does
not affect the behaviour of the vehicle
or the environment.
For more information and the precautions to
take before starting work on the 12 V batter y
,
refer to the corresponding section.
Versions 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.
