Malfunctions
If a fault occurs, this warning lamp
comes on accompanied by a
message and an audible signal.
In the event of a fault with the
power steering, this warning lamp
flashes in the instrument panel,
accompanied by a message.
If the lateral distance between your vehicle
and the space is too great, the system may
not be able to measure the space.
Any object projecting beyond the dimensions
of the vehicle (e.g. a ladder on the roof or a
towball) will not be taken into account by the
Park Assist system during a manoeuvre.
In bad weather or in winter, ensure that
the sensors are not covered by road dirt,
ice or snow.
In the event of a fault, have the system
checked by a CITROËN dealer or a
qualified workshop.High pressure jet washing
When washing your vehicle, keep the lance at
least 12 inches (30
cm) away from the sensors.
Contact a CITROËN dealer or a qualified
workshop.
Under-inflation detection
System which automatically checks the
pressures of the tyres while driving.
The system monitors the pressure in all four
tyres, as soon as the vehicle is moving.
It compares the information given by the wheel
speed sensors with reference values, which
must be reinitialised ever y time the tyre
pressures are adjusted or a wheel changed .
The system triggers an alert as soon as it
detects a drop in the pressure of one or more
tyres. The under-inflation detection system 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 (including the
spare wheel) every month as well as
before a long journey.
Driving with under-inflated tyres worsens
road-holding, lengthens braking distances,
causes premature wear of the tyres,
particularly in adverse conditions (heavy
loads, high speeds, long journeys).
Driving with under-inflated tyres
increases fuel consumption.
The inflation pressures defined for your
vehicle can be found on the tyre pressure
label.
For more information on the
Identification markings , refer to the
corresponding section.

Fuel used for petrol engines
The petrol engines are compatible with biofuels
that conform to current and future European
standards and which can be obtained from
filling stations:Petrol that meets standard EN228,
mixed with a biofuel that meets
standard EN15376.
The only petrol additives authorised for
use are those that meet the B715001
standard.
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
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 that meets
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. 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 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.
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 trade name, etc.) to ensure
correct operation of the engine.
For any additional information, contact a dealer.
Compatibility of fuels
Diesel fuel that meets standard
EN590
mixed with a biofuel that meets
standard EN14214 (possibly containing
up to 7% Fatty Acid Methyl Ester).

Fuel tank
Tank capacity: approximately 45 litres.
I f you have put the wrong fuel in your
vehicle, you must have the fuel tank
drained and filled with the correct fuel
before star ting the engine.
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.
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".

Checking levels
Check all of these levels regularly, in line with
the manufacturer's service schedule. Top them
up if necessary, unless other wise indicated.
If a level drops significantly, have the
corresponding system checked by a CITROËN
dealer or a qualified workshop. The fluid must comply with the
manufacturer's recommendations and with
the vehicle's engine. 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
or indeed very corrosive.
Do not discard used oil or fluids into
sewers or onto the ground.
Take used oil to a CITROËN dealer or
a qualified workshop and dispose of
it in the containers reser ved for this
purpose.
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. To ensure that the reading is correct, your
vehicle must be parked on a level sur face
with the engine having been off for more
than 30


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

When the engine is warm, the temperature of
the coolant 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 when you need to
top up in an emergency, place 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 the coolant.The cooling fan may star t after
switching off the engine: take care
with articles and clothing that might be
caught by the fan blades.
Fluid specification
The fluid must conform to the manufacturer's
recommendations.
Screenwash fluid level
A low coolant level presents a risk of serious
damage to your engine.
Top up the fluid when necessary.Fluid specification
The screenwash fluid must be topped up with a
ready for use mix.
In winter (temperatures below zero), a fluid with
antifreeze must be used that is appropriate for
the prevailing conditions, in order to preser ve
the elements of the system (pump, tank, ducts,
e t c .) .
Filling with pure water is prohibited under all
circumstances (risk of freezing, limestone
deposits, etc.).
