Speed limiter
The system prevents the vehicle
from exceeding the speed setting
programmed by the driver.
Speed selection is made with the vehicle
stationary and the engine running or with
the vehicle moving and 2nd gear or higher
engaged.
The minimum speed that can be programmed
is 19

mph (30 km/h).
The vehicle responds to the driver's foot
pressure on the accelerator until resistance is
felt in the pedal, which signifies that the vehicle
has reached the programmed speed.
However, pressing the pedal beyond this point
of resistance to the floor permits exceeding
the programmed speed. To resume use of
the limiter, simply reduce the pressure on
the accelerator pedal gradually and return to
a


speed below the programmed speed. 1.
Selecting the limiter function.
2. Activation/deactivation of the function.
3. Programming a
speed.
The function selection status and the
programmed speed are displayed in the
instrument panel screen. The speed limiter is a
driving aid that
cannot, in any circumstances, replace the
need to obser ve speed limits or the need
for vigilance on the part of the driver.

Compatibility of fuels

Fuel used for Diesel
engines
The diesel engines are compatible with biofuels
that conform to current and future European
standards and which can be obtained from
filling stations.Diesel fuel that meets standard
EN590
mixed with a biofuel that
meets standard EN14214 (possibly
containing up to 7% Fatty Acid
Methyl Ester).
Diesel fuel that meets standard
EN16734
mixed with a biofuel that
meets standard EN14214 (possibly
containing up to 10% Fatty Acid
Methyl Ester).
Paraffinic Diesel fuel that meets
standard EN15940
mixed with
a
biofuel that meets standard
EN14214 (possibly containing up to
7% Fatty Acid Methyl Ester). For 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,
domestic fuel…) is strictly prohibited (risk
of damage to the engine and fuel system).
The only Diesel additives authorised
for use are those that meet the
B715000


standard.
Diesel at low temperature
At temperatures below 0°C (+32°F), the
formation of paraffins in summer-type Diesel
fuels could entail an abnormal operation
of the fuel supply circuit. To avoid this, we
recommend using winter-type Diesel fuel and
keeping the fuel tank more than 50% full.
If, despite this, at temperatures below -15°C
(+5°F) the engine has problems starting,
just leave the vehicle in a garage or heated
workshop for a
little while.
The use of B20

or B30

fuel meeting
standard EN16709

is possible in
your Diesel engine. However, this
use, even occasional, requires strict
application of the special ser vicing
conditions referred to as "Arduous
conditions".
Travelling abroad
Cer tain fuels could damage the engine of
your vehicle.
In cer tain countries, the use of a
par ticular
fuel may be required (specific octane
rating, specific sales name, etc.) to ensure
correct operation of the engine.
For any additional information, contact a dealer.

For access to the reser voir filler cap, remove
the protective cover by turning its three fixing
screws a quarter turn, then remove the second
cover fitted to the cap.
Engine coolant level
Check the coolant level regularly.
It is normal to top up this fluid
between two services.
Check the coolant level regularly,
according to the use made of your vehicle
(every 3,000
miles (5,000 km)/3 months);
if necessary, top up using coolant
recommended by the manufacturer.
The check and top up must only be done
with the engine cold.
A low coolant level presents a
risk of
serious damage to your engine.
When the engine is hot, the temperature of the
coolant is regulated by the electric fan. This
may operate with the ignition off; furthermore,
because the cooling system is under pressure,
wait for at least one hour after the engine has
stopped before carrying out any work. F

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.

Practical information

Operation
This filter, fitted in the exhaust system,
accumulates particles of soot. The engine
management unit controls the automatic
periodic elimination of the soot particles
(regeneration).
The regeneration procedure is triggered
depending on the amount of particles
accumulated and the vehicle use conditions.
During this phase, you may notice some
unusual phenomena – increased idling speed,
cooling fan running, increase in smoke and
higher exhaust gas temperature – which does
not affect the operation of the vehicle or the
environment.After prolonged idling or driving at very
low speeds, you may occasionally notice
water vapour being emitted from the
exhaust when accelerating. This is of no
consequence to the running of the vehicle
or to the environment. Because of the higher exhaust gas
temperature resulting from the normal
operation of the particle filter, it is
recommended that you do not park the
vehicle over inflammable materials (grass,
dry leaves, pine needles, etc.) so as to
avoid any risk of fire.
Saturation/Regeneration
If there is risk of blockage of the
filter, this warning lamp comes on in
the instrument panel.
This alert tells you that the particle filter is
starting to saturate (in conditions of urban
driving of exceptionally long duration: low
speeds, traffic jams, etc.).
To regenerate the filter, it is advised to drive
as soon as possible, when traffic conditions
and the law permit, at a
speed of at least
37

mph (60 km/h), with an engine speed above
2,000

rpm for about fifteen minutes (until the
warning lamp and/or the message disappears).
If possible, avoid switching off the engine
before the end of the filter regeneration;
repeated interruptions could cause premature
deterioration of the engine oil. It is not
recommended to end regeneration of the filter
with the vehicle stationary.
Malfunction
If this alert persists, do not ignore the warning;
it indicates that a fault has occurred in the
exhaust system/particle filter assembly.
Have the whole system checked by a
CITROËN
dealer or a
qualified workshop.
Manual gearbox
The gearbox does not require any
maintenance (no oil change).
Brake pads
Brake wear depends on the style
of driving, particularly in the case
of vehicles used in town, over short
distances. It may be necessary to
have the condition of the brakes
checked, even between vehicle
services.
If this warning lamp comes on, have
the brake pad wear checked by
a
CITROËN dealer or a qualified
workshop.
