Eco-driving
Eco-driving
Eco-driving refers to a range of everyday
practices that allow the motorist to optimise their
fuel consumption and CO
2emissions.
Optimise your use of the gearbox
With a manual gearbox, move off gently and
change up promptly. While accelerating, change
up early.
With an automatic gearbox, favour automatic
mode and avoid pressing the accelerator pedal
heavily or suddenly.
The gear efficiency indicator prompts you to
engage the most suitable gear: whenever this
indication is displayed on the instrument panel,
follow it straight away.
With an automatic gearbox, this indicator
appears only in manual mode.
Drive smoothly
Maintain a safe distance between vehicles, use
engine braking rather than the brake pedal and
press the accelerator gradually. These attitudes
help to save fuel, reduce CO
2 emissions and
decrease general traffic noise.
If the vehicle has the steering-mounted
"CRUISE" control, use cruise control at speeds
above 25 mph (40

km/h) when the traffic is
flowing well.
Use electrical equipment wisely
Before moving off, if the passenger compartment
is too warm, ventilate it by opening the windows
and air vents before using the air conditioning.
At speeds above 31
mph (50 km/h), close the
windows and leave the air vents open.
Consider using equipment that can help keep
the temperature in the passenger compartment
down (sunroof blind and window blinds, etc.).
Unless automatically regulated, switch off the air
conditioning as soon as the desired temperature
has been reached.
Switch off the demisting and defrosting functions,
if they are not managed automatically.
Switch off the heated seat as soon as possible.
Switch off the headlamps and foglamps when
the visibility conditions do not require their use.
Avoid running the engine before moving off,
particularly in winter; your vehicle will warm up
much faster while driving.
As a passenger, avoid connecting your
multimedia devices (film, music, video game,
etc.) to help reduce consumption of electrical
energy, and hence fuel.
Disconnect all portable devices before leaving
the vehicle.
Limit the causes of excess consumption
Spread loads throughout the vehicle; place the
heaviest items in the boot, as close as possible
to the rear seats.
Limit the loads carried in the vehicle and
minimise wind resistance (roof bars, roof rack, bicycle carrier, trailer, etc.). Preferably, use a
roof box.
Remove roof bars and roof racks after use.
At the end of winter, remove snow tyres and refit
summer tyres.
Avoid using the SPORT mode for too long, in
order to limit your fuel consumption.
Comply with servicing instructions
Check tyre pressures regularly, with the tyres
cold, referring to the label in the door aperture on
the driver's side.
Carry out this check in particular:
–

before a long journey
.
–

at each change of season.
–


after a long period out of use.
Do not overlook the spare wheel and, where
applicable, the tyres on your trailer or caravan.
Have your vehicle serviced regularly (engine oil,
oil filter

, air filter, passenger compartment filter,
etc.) and observe the schedule of operations in
the manufacturer's service schedule.
With a BlueHDi Diesel engine, if the SCR system
is faulty, your vehicle will emit pollution. Visit
a CITROËN dealer or a qualified workshop
as soon as possible to restore your vehicle’s
nitrogen oxide emissions to regulatory
compliance.
When filling the fuel tank, do not continue after
the third nozzle cut-out, to avoid overflow.
You will only see the fuel consumption of your
new vehicle settle down to a consistent average
after the first 1,900 miles (3,000 kilometres).

Practical information
Compatibility of fuels
Petrol fuels conforming to the EN228 standard
containing up to 5% and 10% ethanol
respectively.

Diesel fuels conforming to the EN590, EN16734
and EN16709 standards and containing up to
7%, 10%, 20% and 30% fatty acid methyl ester
respectively. The use of B20 or B30 fuels, even
occasionally, imposes special maintenance
conditions referred to as "Arduous conditions".

Paraffinic Diesel fuel conforming to the EN15940
standard.
The use of any other type of (bio) fuel (vegetable or animal oils, pure or diluted,
domestic fuel, etc.) is strictly prohibited (risk
of damage to the engine and fuel system).
The only fuel additives authorised for use are those that meet the B715001 (petrol)
or B715000 (Diesel) standards.
Diesel at low temperature
At temperatures below 0 °C (+32 °F), the
formation of paraffins in summer-type Diesel fuels could prevent the engine from operating
correctly
. In these temperature conditions, use
winter-type Diesel fuel and keep the fuel tank
more than 50 % full.
At temperatures below -15 °C (+5 °F) to avoid
problems starting, it is best to park the vehicle
under shelter (heated garage).
Travelling abroad
Certain fuels could damage your vehicle’s
engine.
In certain countries, the use of a particular
fuel may be required (specific octane rating,
specific trade name, etc.) to ensure correct
operation of the engine.
For all additional information, consult a dealer.
Refuelling
Fuel tank capacity (depending on version):
approximately 47 or 50 litres (petrol) or
approximately 45 or 50 litres (Diesel).
Reserve level: approximately 5 litres.
Low fuel level
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.
When it first comes on, about 5 litres of fuel
remain in the tank.
This warning lamp will come on every time
the ignition is switched on, accompanied by a
message and an audible signal, until a sufficient
addition of fuel is made. This audible signal and
message are repeated with increasing frequency
as the fuel level drops and approaches " 0".
You must refuel as soon as possible to avoid
running out of fuel.
For more information on Running out of
fuel (Diesel), refer to the corresponding
section.
Stop & Start
Never refuel with the engine in STOP
mode; you must switch off the ignition.
Refuelling
Additions of fuel must be of at least 5 litres, in
order to be registered by the fuel gauge.
Opening the filler cap may create a noise caused
by an inrush of air. This vacuum is entirely
normal, resulting from the sealing of the fuel
system.
To refuel in complete safety:
►

Y
ou must switch off the engine.

Practical information
city driving), change it twice as often, if
necessary.
A clogged passenger compartment filter
can adversely affect air conditioning
system performance and generate
undesirable odours.
Air filter
Depending on the environment and the
use of the vehicle (e.g. dusty atmosphere,
city driving), change it twice as often, if
necessary .
Oil filter
Change the oil filter each time the engine
oil is changed.
Particle filter (Diesel)
The start of saturation of the particle filter
is signalled by the temporary illumination
of this warning lamp, accompanied by a
message warning of the risk of the filter clogging
up.
As soon as the traffic conditions permit,
regenerate the filter by driving at a speed of at
least 37 mph (60 km/h) until the warning lamp
goes off.
If the warning lamp stays on, this
indicates a low Diesel additive level.
For more information on Checking levels,
refer to the corresponding section.
If the level is close to or below the " MIN” mark, it
is essential to top up.
When the engine is hot, the temperature of this
fluid is regulated by the fan.
As the cooling system is pressurised, wait at
least one hour after switching off the engine
before carrying out any work.
In order to avoid the risk of scalding if you need
to top up in an emergency, wrap a cloth around
the cap and unscrew the cap by two turns to
allow the pressure to drop.
Once the pressure has dropped, remove the cap
and top up to the required level.
Screenwash fluid
Top up to the required level when necessary.
Fluid specification
The fluid must be topped up with a ready-to-use
mixture.
In winter (temperatures below zero), a liquid
containing an agent to prevent freezing must
be used which is appropriate for the prevailing
conditions, in order to protect the elements of the
system (pump, tank, ducts, jets, etc.).
Filling with pure water is prohibited under
all circumstances (risk of freezing,
limestone deposits, etc.).
Diesel fuel additive (Diesel
with particle filter)
On reaching the minimum level in the
particle filter additive tank, this warning
lamp comes on fixed, accompanied by an
audible warning and a message warning that the
additive level is too low.
Topping up
This additive must be topped up without delay by
a CITROËN dealer or a qualified workshop.
AdBlue (BlueHDi)
An alert is triggered when the reserve level is
reached.
For more information on the AdBlue range
indicators, refer to the corresponding section.
To avoid the vehicle being immobilised in
accordance with regulations, you must top up the
AdBlue tank.
For more information on the Supply of AdBlue,
refer to the corresponding section.
Checks
Unless otherwise indicated, check these
components in accordance with the
manufacturer's service schedule and according
to your engine.
Otherwise, have them checked by a CITROËN
dealer or a qualified workshop.
Only use products recommended by
CITROËN or products of equivalent
quality and specification.
In order to optimise the operation of
components as important as those in the
braking system, CITROËN selects and offers
very specific products.
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.
For more information on the precautions
to take before any work on the 12 V
battery, 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.

Practical information
For the care of the stickers in the rear
door windows (quarter panels), we
recommend the following:
– Use a wide jet at a temperature of between
25°C and 40°C.
– Where possible, direct the jet at right
angles to the stickers."Top up AdBlue: Starting impossible" – it is
essential to add at least 5 litres.
After refilling
► Refit the blue cap to the tank filler and turn it
clockwise, as far as it will go.
►

Close the fuel filler flap.
Do not dispose of AdBlue® bottles or
containers in the household waste.
Place them in a container reserved for this
purpose or take them back to where you
purchased them.
Advice on care and maintenance
General recommendations
Observe the following recommendations to avoid
damaging your vehicle.
Exterior
Never use a high-pressure jet wash in
the engine compartment, due to the risk
of damaging electrical components.
Do not wash the vehicle in strong sunshine or
extremely cold conditions.
When washing the vehicle at an
automatic roller-brush car wash, be sure
to lock the doors and, depending on version,
remove the electronic key.
When using a pressure washer, hold the
lance at least 30 cm from the vehicle
(particularly when cleaning areas containing
chipped paint, sensors or seals).
Promptly clean up any stains containing
chemicals liable to damage the vehicle's paint
(including tree resin, bird droppings, insect
secretions, pollen and tar).
If justified by the environment, clean the
vehicle more frequently to remove salty
deposits (in coastal areas), soot (in industrial
estates) and mud (in wet or cold areas).
These substances can be highly corrosive.
Contact a CITROËN dealer or a qualified
workshop if you require advice on removing
stubborn stains requiring special products
(such as tar or insect removers).
Preferably, have paint touch-ups performed
by a CITROËN dealer or a qualified
workshop.
Interior
When washing the vehicle, never use a
water hose or high-pressure washer to
clean the interior.
Liquids carried in cups or other open
containers can spill, presenting a risk of
damage if they come into contact with the
controls in the dashboard and centre console.
Take care!
Bodywork
High-gloss paint
Do not use abrasive products or
solvents, petrol or oil to clean the
bodywork.
Never use an abrasive sponge to clean
stubborn stains. Risk of scratching the
paintwork!
Do not apply polish in strong sunshine, or to
plastic or rubber parts.
Use a soft sponge and soapy water or a
pH neutral product.
Gently wipe the bodywork with a clean
microfibre cloth.
Apply polish with the vehicle clean and dry.
Comply with the instructions for use stated on
the product.
Care of the stickers
These styling stickers are treated to give good
resistance to ageing and tearing.
They have been designed to allow you to
customise your vehicle's bodywork.
When washing your vehicle, keep the high-
pressure lance tip at least 30 cm away from the
stickers.
