litres.
Low fuel level
When the level in the tank becomes
low, this warning lamp comes on in
the instrument panel, accompanied
by the display of a
message and an
audible signal. When it first comes
on, there remains about 6


litres of
fuel in the tank.
Refuelling
Fuel top-ups must be of at least 5 litres in order
t o be registered by the fuel gauge.

fuel.
The filler neck is narrower, admitting unleaded
petrol nozzles only.
If your vehicle is fitted with Stop & Start,
never refuel with the engine in STOP
mode; you must switch off the ignition.
Misfuel prevention (Diesel)
(Depending on country of sale.)
Mechanical device which prevents filling the
tank of a Diesel vehicle with petrol.
Operation
Until sufficient fuel is added, this warning lamp
reappears every time the ignition is switched
on, accompanied by the message and the
audible signal. When driving, this message
and audible signal are repeated with increasing
frequency as the fuel level drops towards 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. entirely normal and results from the sealing of
the fuel system.
Practical information

181
It remains possible to use a fuel can to fill
t he tank.
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 a
CITROËN dealer whether your
vehicle is suitable for the fuel pumps in the
country in which you intend to travel.
When a
petrol filler nozzle is introduced into
the fuel filler neck of a 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.
Compatibility of fuels
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
syste m). The only fuel additives authorised for use
are those that meet the B715001 (petrol)
or B715000 (Diesel) standards.
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 respectively
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.
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
Cer tain fuels could damage your vehicle's
engine.
In cer tain countries, the use of a
par ticular
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.

weight, indicated on your vehicle's
registration certificate, the manufacturer's
label as well as in the Technical data
section of this guide.
Complying with the maximum
authorised nose weight (towball)
also includes the use of accessories
(bicycle carriers, tow boxes, etc.).
Obser ve the legislation in force in the
country in which you are driving.
Vehicle equipped with motorised tailgate
with " Hands-Free Tailgate Access "
function
To avoid unwanted opening of the tailgate
when using the towing device:
-

d
eactivate the "Hands-Free Tailgate
Access" function in advance in your
vehicle's configuration menu,
-

o
r remove the electronic key from the
recognition zone, with the tailgate closed.
Towing device
Load distribution
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. The maximum
towed load must be reduced by 10% for every
1,000
metres of altitude. Use towing devices and their genuine
harnesses approved by CITROËN. It
is recommended that the installation
be per formed by a
CITROËN dealer or
a

qualified workshop.
If the towing device is not fitted by
a CITROËN dealer, it must still be
fitted in accordance with the vehicle
manufacturer's instructions.
Important: for versions equipped with
the motorised tailgate with Hands-Free
Tailgate Access function, if a
towing
device other than a
genuine CITROËN
one is installed, it is essential to visit
a
CITROËN dealer or a qualified
workshop to recalibrate the detection
system: risk of "Hands-Free Tailgate
Access" function failure.
Certain driving or manoeuvring aid
functions are automatically disabled if an
approved towing system is used.

Load reduction mode
System which manages the use of certain
functions according to the level of charge
remaining in the battery.
When the vehicle is being driven, the load
reduction function temporarily deactivates
certain functions, such as air conditioning,
heated rear screen, etc.
The deactivated functions are reactivated
automatically as soon as conditions permit.
Snow chains
In wintry conditions, snow chains
improve traction as well as the
behaviour of the vehicle when
braking.
Snow chains must be fitted only to the
front wheels. They must never be fitted to
"space-saver" type spare wheels.

, then contact a CITROËN
dealer or a qualified workshop.
-
B
elow mark B
, then top up the engine oil
immediately.
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).
Used products
Avoid prolonged contact of used oil or
fluids with the skin.
Most of these fluids are harmful to health,
and may be very corrosive.
Do not discard used oil or fluids into
sewers or onto the ground.
Empty used oil into the containers
reser ved for this purpose at a
CITROËN
dealer or a
qualified workshop.
Engine oil
The level is checked either using the
oil level indicator in the instrument
panel when the ignition is switched
on, for vehicles equipped with an
electric gauge, or using the dipstick.
The vehicle must be parked on a level sur face,
w ith the engine stopped for more than 30 minutes.
It is normal to top up the oil level between two
ser vices (or oil changes). It is recommended
that you check the level, and top up if
necessary, every 3,000
miles (5,000 km).
In order to maintain the reliability of the
engine and emissions control system,
never use additives in the engine oil.
Practical information

191
During the 30 minutes after topping up the
o il, the check per formed with the oil level
indicator in the instrument panel when the
ignition is switched on is not valid.
Brake fluid
The level of this fluid should be close
to the " MAX" mark. If not, check the
brake pad wear.
To know how often the brake fluid should be
replaced, refer to the manufacturer's servicing
schedule.
Engine coolant
Check the engine coolant level
regularly.
It is normal to top up this fluid
between two services. The check and top-up must only be done with
the engine cold.
A low level presents a
risk of serious damage
to the engine.
The level of this fluid should be close to the
" MAX " mark but should never exceed it.
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.
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 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.
If topping up, clean the cap before
replacing it. Use only DOT4 brake fluid
from a sealed canister.

fan!Screenwash fluid
Top up to the required level when
necessary.
Fluid specification
The screenwash fluid must be topped up with
a ready for use mix.
In winter (temperatures below zero), a liquid
containing an anti-freeze agent must be
used which is appropriate for the prevailing
conditions, in order to preser ve the elements of
the system (pump, tank, ducts, etc.).
Filling with pure water is prohibited
under all circumstances (risk of freezing,
limestone deposits, jets, etc.).
