2014.5 Citroen C5 fuel

System which reduces fuel consumption by advising the driver to change up.
The system intervenes only when driving
economically.
Depending on the driving situation and your
vehicle's equipment, the system may advise
you to skip one or more gears. You can
follow this instruction without engaging the
intermediate gears.
The gear engagement recommendations must
not be considered compulsory. In fact, the
configuration of the road, the amount of traffic
and safety remain determining factors when
choosing the best gear. Therefore, the driver
remains responsible for deciding whether or not
to follow the advice given by the system.
This function cannot be deactivated.Example:
-

Y
ou are in third gear.
-

Y
ou press the accelerator pedal
moderately. The information appears in the instrument
panel in the form of an arrow accompanied by
the suggested gear.
Gear efficiency indicator*
In the case of driving which makes
particular demands on the per formance
of the engine (firm pressure on the
accelerator pedal, for example, when
overtaking...), the system will not
recommend a gear change.
The system never suggests:
-

e
ngaging first gear,
-
enga

ging reverse gear,
-

e
ngaging a lower gear.
Operation
* Depending on engine. -
T
he system may suggest that you engage
a higher gear, if appropriate.
With an electronic or automatic
gearbox, the system is only active in
manual mode.

Stop & Start
Operation
- with an electronic gearbox, at speeds
below 4 mph (6 km/h), press the brake
pedal or put the gear lever in position N .
Going into engine STOP
mode
The "ECO" warning lamp comes
on in the instrument panel and the
engine goes into standby:
If your vehicle is fitted with the
system, a time counter calculates
the sum of the periods in STOP
mode during a journey. It rests itself
to zero every time the ignition is
switched on with the key.
Special cases: STOP mode not
available
In this case, the "ECO" warning
lamp flashes for a few seconds then
goes
off.
This operation is perfectly normal. STOP mode is not invoked when:
-

t

he driver's door is open,
-

t

he driver's seat belt is not fastened,
-

t

he vehicle has not exceeded 6 mph
(10 km/h) since the last engine start using
the key,
-

t

he electric parking brake is applied or
being applied,
-

t

he engine is needed to maintain a
comfortable temperature in the passenger
compartment,
-

d

emisting is active,
-

s

ome special conditions (battery charge,
engine temperature, braking assistance,
ambient temperature...) where the engine is
needed to assure control of a system.
The Stop & Start

system puts the engine temporarily into standby - STOP mode - during stops in the traffic (red lights, traffic jams, or other...).
The

engine restarts automatically - START mode - as soon as you want to move off. The restart takes place instantly, quickly and silently.
Per fect for urban use, the Stop & Start system reduces fuel consumption and exhaust emissions as well as the noise level when stationary.
Never refuel with the engine in STOP
mode; you must switch off the ignition
with the key. For your comfort, during parking
maoeuvres, STOP mode is not
available for a few seconds after
coming out of reverse gear.
STOP mode does not affect the
functionality of the vehicle, such as for
example, braking, power steering...

Tyre under-inflation detection
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.The tyre under-inflation detection
system is an aid to driving which 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 regularly
(including the spare wheel) and before
a long journey.
Driving with under-inflated tyres
adversely affects road holding,
extends braking distances and causes
premature tyre wear, particularly under
arduous conditions (vehicle loaded,
high speed, long journey).
The tyre pressures for your vehicle can
be found on the tyre pressure label (see
the "Identification markings" section).
The tyre pressures must be checked
when the tyres cold (vehicle stopped
for 1 hour or after driving for less then
6 miles (10 km) at moderate speed).
Other wise, add 0.3 bar to the values
indicated on the label.
Driving with under-inflated tyres
increases fuel consumption.
A pressure sensor is located in the valve of
each tyre (except the spare wheel).
The system triggers an alert if a drop in
pressure is detected in one or more tyres.

Fuel tank
Capacity of the tank: approximately 71 litres*.
Low fuel level
When the minimum level
in the tank is reached, this
warning lamp comes on in the
instrument panel, accompanied
by an audible warning and a message in the
multifunction screen. When it first comes on,
there remains around 5 litres of fuel in the tank.
You must refuel to avoid running out of fuel.

While you are refuelling, the engine must be
stopped and the ignition switched off.
For a petrol engine with a catalytic
converter, unleaded fuel is compulsory.
Opening the fuel flap Refuelling
* 55 litres for Slovakia. Additions of fuel must be of at least
5 litres to be taken into account by the
fuel gauge.
The filler neck is narrower to ensure
that only unleaded petrol nozzles can
be put in.
Opening the filler cap may create a
noise of an inrush of air. This vacuum,
which is entirely normal, is caused by
the sealing of the fuel system.
With Stop & Start, never refuel with the
system in STOP mode; you must switch
off the ignition with the key.

Misfuel prevention (Diesel)*
When a petrol filler nozzle is introduced into the
fuel filler neck of your Diesel vehicle, it comes
into contact with the flap. The system remains
closed and prevents filling.
Do not persist but introduce a Diesel type
filler nozzle.
* According to country of sale. Mechanical device which prevents filling the tank of a Diesel vehicle with petrol. It avoids the risk of
engine damage that can result from filling with the wrong fuel.
Located in the filler neck, the misfuel prevention device appears when the filler cap is removed.
Operation
It remains possible to use a fuel can to
fill the tank.
In order to ensure a good flow of fuel,
do not place the nozzle of the fuel can
in direct contact with the flap of the
misfuel prevention device and pour
s l ow l y.

Fuel used for petrol
engines
The petrol engines are compatible with
E10 bio-petrol (containing 10 % ethanol),
conforming to European standards EN 228
and EN 15376.
E85 type fuels (containing up to 85 % ethanol)
are reserved exclusively for vehicles marketed
for the use of this type of fuel (BioFlex
vehicles). The quality of the ethanol must
comply with European standard EN 15293.
Fuel used for Diesel
engines
The Diesel engines are compatible with
biofuels which conform to current and future
European standards (Diesel fuel which
complies with standard EN 590 mixed with
a biofuel which complies with standard
EN
14214) available at the pumps (containing
up to 7 % Fatty Acid Methyl Ester).
B30 biofuel can be used in certain Diesel
engines. However, this use, even occasional,
requires strict application of the special
servicing conditions. 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).
Travelling abroad
As Diesel fuel pump nozzles may
be different in other countries, the
presence of the misfuel prevention
device may make refuelling impossible.
Before travelling abroad,
we
recommend that you check with the
CITROËN dealer network, whether your
vehicle is suitable for the fuel pumps in
the country in which you want to travel.

Removing the cover
Bleeding water from the
fuel filter
Bleed regularly (at each oil change).
To bleed the water, slacken the bleed screw or
the water in diesel fuel sensor, located at the
base of the filter.
Continue until all the water has flowed out.
Then tighten the bleed screw or the water
detection sensor.

the protective cover, operate the manual
priming pump, until some resistance is felt,
F

o
perate the starter motor while depressing
the accelerator pedal slightly until the
engine starts. HDi engines make use of advanced
technology.
For any work on your vehicle, contact
a qualified workshop that has the
skills and equipment required, which a
CITROËN dealer is able to provide.
If the engine fails to start at the first attempt,
wait fifteen seconds before trying again.
If the engine fails to start after a few attempts,
operate the priming pump again and then try to
start the engine.
When the engine is idling, accelerate slightly to
complete the bleeding of the circuit.
