Low fuel levelfixed. When it first comes on there remains
approximately 5 litres of fuel in the
tank. You must refuel as soon as possible to avoid running
out of fuel.
This warning lamp will come on every time the ignition
is switched on, until a sufficient addition of fuel is
made.
Fuel tank capacity: approximately 50 litres (petrol) or
48 litres (Diesel); depending on version: approximately
30 litres (petrol or Diesel).

Ventilation
Air flow paths
The incoming air follows various routes
depending on the controls selected by the
driver:
-
d
irect arrival in the passenger
compartment (air intake),
-
p

assage through a heating circuit (heating),
-

p
assage through a cooling circuit (air
conditioning).
The temperature control enables you to obtain
the level of comfort required by mixing the air of
the various circuits.
The air distribution control enables you to
diffuse the air in the passenger compartment
combining several air vents.
The air flow control enables you to increase or
reduce the speed of the ventilation fan.
Air intake
The air circulating in the passenger compartment
is filtered and originates either from the outside
via the grille located at the base of the windscreen
or from the inside in air recirculation mode.
Control panel
The controls of this system are grouped
together on control panel A on the centre
console.

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 with an electric oil
level gauge, or using the dipstick.
Checking using the dipstick
A = MA X
Check all of these levels regularly, in line with the maintenance and warranty guide. 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.
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
sur face 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). B = MINIf you find that the level is above the A mark or
below the B mark, do not star t the engine
.

I
f the level is above the MAX
mark (risk
of damage to the engine), contact a
CITROËN dealer or a qualified workshop.
-
I
f the level is below the MIN
mark, you
must top up the engine oil.
Oil grade
before topping-up the oil or changing the oil,
check that the oil is the correct grade for your
engine and conforms to the manufacturer's
recommendations.
Refer to the "Petrol engine" or "
di

esel engine"
section for the location of the dipstick in the
engine compartment of your vehicle.

Coolant level
The coolant level should be close
to the "MaX" mark but should never
exceed it.
Fluid specification
For optimum cleaning and to avoid freezing,
this fluid must not be topped up or replaced
with plain water.
In wintry conditions, it is recommended that you
use an ethyl alcohol or methanol based fluid.
Fluid specification
The coolant must conform to the
manufacturer's recommendations.
Changing the coolant
The coolant does not have to be replaced at
routine services.
Screenwash fluid level
When the engine is warm, the temperature of
the coolant is regulated by the fan. Top up the level when necessary.
The cooling fan may star t after switching
off the engine: take care with ar ticles 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.

Towing a trailer, ...
Driving advice
Cooling
Towing a trailer on a slope increases the
temperature of the coolant.
as t
he fan is electrically controlled, its cooling
capacity is not dependent on the engine speed.
F

T
o lower the engine speed, reduce your
speed.
The maximum towed load on a long incline
depends on the gradient and the ambient
temperature.
In all cases, keep a check on the coolant
temperature.
Side wind
F Take into account the increased sensitivity to side wind. F

I
f the warning lamp and the
STOP warning lamp come on,
stop the vehicle and switch off
the engine as soon as possible.
Towbar suitable for the attachment of a trailer or installation of a bicycle carrier, with additional lighting and signalling.
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.
a
b
ove
1
000 metres, the maximum towed load must
be reduced by 10
% for every 1 000 metres of
altitude.
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 CITR
oËn

dealer or a
qualified workshop.
If the towbar is not fitted by a CITROËN
dealer, it is imperative that it is
fitted in accordance with the vehicle
manufacturer's instructions.
Driving with a trailer places greater demands
on the towing vehicle and the driver must take
particular care. Your vehicle is primarily designed for transporting people and luggage, but it may also be used for towing a trailer.
Refer to the "Technical data" section for details
of the weights and towed loads which apply to
your vehicle.
