Fuel tank

Capacity of the tank: approximately 71 litres*.

Low fuel level

When the low fuel 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 display screen. When it
first comes on, there remains
around 5 litres of fuel in the tank.

F Press at the top left corner, then pull on its

edge.

While you are refuelling, the engine must be
stopped and the ignition switched off.
F

Turn the key a quarter turn to lock and

unlock the filler cap.

F

When refuelling, place the cap on hook A.

F

Fill the tank, but do not persist after the

third cut-off

; this could cause your vehicle

to malfunction.

For a petrol engine with a catalytic
converter, the use of unleaded fuel is
compulsory.
The filler neck is narrower to ensure that only
unleaded petrol nozzles can be put in.

Opening the fuel flap

Refuelling

Additions of fuel must be of at least
5 litres to be taken into account by the
fuel gauge.
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.

* 55 litres for Slovakia.

You must refuel to avoid running out of fuel.

Fuel used for petrol engines

The petrol engines are compatible with
bio-fuels that conform to current and future
European standards and can be obtained from
filling stations:

Fuel used for Diesel
engines

The Diesel engines are compatible with
biofuels that conform to current and future
European standards and can be obtained from
filling stations:

The only Diesel additives authorised for
use are those that meet the B715000
standard.

- Petrol that meets the EN228

standard, mixed with a bio-
fuel meeting the EN15376
standard.

The only petrol additives authorised for
use are those that meet the B715001
standard.

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).

- 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).

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
servicing conditions referred to as
"Arduous conditions".

For more information, contact a CITROËN
dealer or a qualified workshop.

Travelling abroad

Certain fuels could damage the
engine of your vehicle. In certain
countries, the use of a particular fuel
may be required (specific octane
rating, specific sales name…) to
ensure correct operation of the
engine.
For any additional information, contact
your dealer.

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.

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
slowly.

* Depending on the country of sale.

Travelling abroad

As Diesel fuel pump nozzles may
be different in other countries, the
presence of the misfuel prevention
device may make refuelling impossible.
Not all Diesel vehicles are fitted with
misfuel protection, so 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
intend to travel.

Snow chains

In wintry conditions, snow chains improve traction as well as the behaviour of the vehicle when braking.

The snow chains must be fitted only
to the front wheels. They must never
be fitted to "space-saver" type spare
wheels.

Take account of the legislation in force
in your country on the use of snow
chains and the maximum running speed
authorised.

Avoid driving with snow chains on roads
that have been cleared of snow, to
avoid damaging your vehicle's tyres and
the road surface. 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.

Advice on installation

F

If you have to fit the chains during a

journey, stop the vehicle on a flat surface
on the side of the road.

F

Apply the parking brake and position any

wheel chocks to prevent movement of your
vehicle.

F

Fit the chains following the instructions

provided by the manufacturer.

F

Move off gently and drive for a few

moments, without exceeding 30 mph
(50 km/h).

F

Stop your vehicle and check that the snow

chains are correctly tightened.

Use only the chains designed to be fitted to the
type of wheel fitted to your vehicle:

Original tyre size

Chain specification

225/60 V16

Maximum link size:

9 mm

225/55 W17

245/45 W18

These tyres cannot

be fitted with chains

245/40 Y19

For more information on snow chains, contact a
CITROËN dealer or a qualified workshop.

It is strongly recommended that before
you leave, you practise fitting the snow
chains on a level and dry surface.

Energy economy mode

System which manages the duration of use of
certain functions to conserve a sufficient level
of charge in the battery.
After the engine has stopped, you can still use
functions such as the audio and telematics
system, windscreen wipers, dipped beam
headlamps, courtesy lamps, etc. for a
maximum combined duration of about forty
minutes.

Switching to economy mode

A message appears in the instrument panel
screen indicating that the vehicle has switched
to economy mode and the active functions are
put on standby.

If a telephone call is being made at this
time, it will be maintained for around
10 minutes with the Bluetooth

®

hands-

free system of your audio system.

Exiting economy mode

These functions are reactivated automatically
next time the vehicle is driven.
In order to restore the use of these functions
immediately, start the engine and let it run:
- for less than ten minutes, to use the

equipment for approximately five minutes,

- for more than ten minutes, to use the

equipment for up to approximately
thirty minutes.

Let the engine run for the duration specified to
ensure that the battery charge is sufficient.
Do not repeatedly and continuously restart the
engine in order to charge the battery.

A flat battery prevents the engine from
starting.

Towing a trailer

Your vehicle is primarily designed for transporting people and luggage, but it may also be used for towing a trailer.

Side wind

F

Take into account the increased sensitivity

to side wind.

When towing

We recommend the use of genuine
CITROËN towbars and their harnesses
that have been tested and approved
from the design stage of your vehicle,
and that the fitting of the towbar is
entrusted to a CITROËN dealer or a
qualified workshop.
If the towbar is not fitted by a
CITROËN dealer, it must still be
fitted in accordance with the vehicle
manufacturer's instructions.

Distribution of loads

F Distribute the load in the trailer so that the

heaviest items are as close as possible to the
axle, and the nose weight approaches the
maximum permitted without exceeding it.

Air density decreases with altitude, thus
reducing engine performance. Above
1 000 metres, the maximum towed load must
be reduced by 10 % for every 1 000 metres of
altitude.

For more information on Weights, refer
to the corresponding section.

Driving with a trailer places greater
demands on the towing vehicle and the
driver must take particular care.
For more information on Driving
advice

, particularly when towing, refer

to the corresponding section.

You must observe the maximum trailer
weight, indicated on the registration
certificate or in the technical
specification for your vehicle.

For more information on Weights (and
the towed loads which apply to your
vehicle) refer to the corresponding
section.

C5_en_Chap07_info-pratiques_ed01-2016

Blanking cover

When towing, you must remove the blanking
cover in the front bumper as well as the bonnet
seal if fitted.
Contact a CITROËN dealer or a qualified
workshop for this.

Tyres

F

Check the tyre pressures of the towing

vehicle and of the trailer, observing the
recommended pressures.

Lighting

F

Check the electrical lighting and signalling

on the trailer and the headlamp beam
height of your vehicle.

For more information on Adjusting the
headlamps

, refer to the corresponding section.

The rear parking sensors will be
deactivated automatically to avoid the
audible signal if a genuine CITROËN
towbar is used.

Braking

Towing a trailer increases the braking distance.
To avoid overheating of the brakes, the use of
engine braking is recommended.

Cooling

Towing a trailer on a slope increases the
temperature of the coolant.
As the fan is electrically controlled, its cooling
capacity is not dependent on the engine speed.
F

To lower the engine speed, reduce your

speed.

The maximum towed load on a long incline
depends on the gradient and the exterior
temperature.
In all cases, keep a check on the coolant
temperature.

F

If the warning lamp and the

STOP

warning lamp come on,

stop the vehicle and switch off
the engine as soon as possible.

C5_en_Chap07_info-pratiques_ed01-2016

Roof bars

The design of your vehicle requires the use
of roof bars that are tested and approved by
CITROËN, for your safety and to avoid damage
to the roof and tailgate.
Regardless of the type of loading equipment
to be transported on the roof (bicycle carrier,
ski carrier...), it is imperative that you add
transverse roof bars. Any securing or lashing to
components other than the roof bars is strictly
prohibited.

Recommendations

F

Distribute your load evenly, avoiding

overloading on one side.

F

Arrange the heaviest part of the load as

close as possible to the roof.

F Anchor the load securely and draw

attention to it if any part of it is
overhanging.

F

Drive gently, as the vehicle will be more

liable to the effects of side winds (vehicle
stability may be altered).

F

Remove the roof bars as soon as they are

no longer needed.

Maximum load that can be distributed
on the roof bars (for a loading height
not exceeding 40 cm; except bicycle
carrier): 80 kg.
If the height exceeds 40 cm, adapt your
speed to the profile of the road to avoid
damaging the roof bars and the fixings
on the roof.

Please refer to national legislation in
order to comply with the regulations
concerning the transportation of objects
which are longer than the vehicle.

Checking levels

Engine oil level

The check is carried out either when
the ignition is switched on using the
oil level indicator in the instrument
panel for vehicles so equipped, or
using the dipstick.

Check all of these levels regularly, in line with the manufacturer's service schedule. Top them up if necessary, unless otherwise indicated.
If a level drops significantly, have the corresponding system checked by a CITROËN dealer or a qualified workshop.

If you find that the level is above the A

mark or

below the B

mark, do not start the engine.

-

If the level is above the MAX

mark (risk

of damage to the engine), contact a
CITROËN dealer or a qualified workshop.

-

If the level is below the MIN

mark, you

must top-up the engine oil.

Take care when working under the
bonnet, as certain areas of the engine
may be extremely hot (risk of burns) and
the cooling fan could start at any time
(even with the ignition off).

To ensure that the reading is correct, your
vehicle must be parked on a level surface
with the engine having been off for more than
30 minutes.

It is normal to top-up the oil level between
two services (or oil changes). CITROËN
recommends that you check the level, and top-
up if necessary, every 3 000 miles (5 000 kms).

Checking using the dipstick

The location of the dipstick is shown in the
corresponding underbonnet layout view.
F

Take the dipstick by its coloured grip and

remove it completely.

F

Wipe the end of the dipstick using a clean

non-fluffy cloth.

F

Refit the dipstick and push fully down, then

pull it out again to make the visual check:
the correct level is between the marks A
and B

.

A = MAX

B = MIN

recommendations.

Topping-up the engine oil level

The location of the oil filler cap is shown in the
corresponding underbonnet layout view.
F Unscrew the oil filler cap to reveal the filler

aperture.

F

Add oil in small quantities, avoiding any

spills on engine components (risk of fire).

F

Wait a few minutes before checking the

level again using the dipstick.

F

Add more oil if necessary.

F

After checking the level, carefully refit the

oil filler cap and the dipstick in its tube.

After topping-up the oil, the check when
switching on the ignition with the oil
level indicator in the instrument panel
is not valid during the 30 minutes after
topping-up.

Engine oil change

Refer to the manufacturer's service schedule
for details of the interval for this operation.
In order to maintain the reliability of the engine
and emission control system, never use
additives in the engine oil.

manufacturer's recommendations.

Power steering or power
steering and suspension
fluid level

For topping up, it is necessary to go
to a CITROËN dealer or a qualified
workshop.

Coolant level

The coolant level should be close
to the "MAX" mark but should never
exceed it.

Fluid specification

The coolant must conform to the
manufacturer's recommendations.

The cooling fan may start after switching
off the engine: take care with articles and
clothing that might be caught by the fan
blades.

In addition, as the cooling system is
pressurised, wait at least one hour after
switching off the engine before carrying out any
work.
To avoid any risk of scalding, unscrew the cap
by two turns to allow the pressure to drop.
When the pressure has dropped, remove the
cap and top-up the level.

When the engine is warm, the temperature of
the coolant is regulated by the fan.
