Warning/indicator lampis on Cause Action / Observations
Maximum coolant
temperature fixed.
The temperature of the cooling
system is too high. Stop as soon as it is safe to do so.
Wait until the engine has cooled down before topping
up the level, if necessary.
If the problem persists, contact a CITR
oËn

dealer or
qualified workshop.
Engine oil
pressure fixed.
There is a fault with the engine
lubrication system. You must stop as soon it is safe to do so.
Park, switch off the ignition and contact a CITROËN
dealer or a qualified workshop.
Battery charge fixed. The battery charging circuit has a
fault (dirty or loose terminals, slack or
cut alternator belt, ...). The warning lamp should go off when the engine is
started.
If it does not go off, contact a CITR
oËn

dealer or a
qualified workshop.
Low fuel level
fixed. 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),
46
litres (Diesel) or 37 litres (LPG); depending on
version: approximately 30 litres (petrol or Diesel).
ne

ver continue to drive until you run out of fuel as
this could damage the emission control and injection
systems.

Ventilation
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.
Air treatment
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 blower.
Control panel
The controls of this system are grouped
together on control panel A on the centre
console.

4. Air conditioning on/off
Press this button to switch off the air
conditioning.
Stopping the air conditioning may cause some
problems (humidity, misting).
au

tomatic operation of the air conditioning is
resumed when the button is pressed again.
The

symbol "A /C " is displayed.
5. Air intake / Air recirculation
Press this button for recirculation of
the interior air. The air recirculation
symbol 5 is displayed.
air recirculation enables the passenger compartment
to be isolated from exterior odours and smoke.
6. Air distribution adjustment
Pressing this button several times in
succession enables the air flow to be
directed in turn towards:
-

t

he windscreen and the side windows
(demisting or defrosting),
-

7. Air flow adjustment
Press the "full fan" button to
increase the air flow.
The air flow symbol, the fan, fills progressively
according to the value requested.
Switching the system off
Press the air flow "empty fan"
button 7 until the fan symbol
disappears.
This action switches off all of the functions of
the air conditioning system.
Thermal comfort is no longer controlled.
A

slight flow of air resulting from the movement
of the vehicle, remains perceptible however.
Pressing the air flow "full fan" button 7 or on
"AUTO" reactivates the system with the values
set before it was switched off. Press the "empty fan"
button to
decrease the air flow.
Press this button again or press the "AUTO"

button to resume automatic management of
the intake of air. The air recirculation symbol 5
goes off.
Avoid driving for long periods with the air
conditioning switched off (risk of misting
and reduction of the air quality in the cabin).
For maximum cooling or heating of the
cabin, it is possible to go beyond the
minimum 14 or maximum 28 values.

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.
Checking using
the dipstick
Refer to the "Petrol engine" or "di esel engine"
section for the location of the dipstick in the
engine compartment of your vehicle.
F

T
ake the dipstick by its coloured grip and
remove it completely.
F

W
ipe the end of the dipstick using a clean
non-fluffy cloth.
F

R
efit 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 .
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.
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.
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).
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). A = MA X
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.

Additive level (Diesel with
particle filter)
according to your version of instrument panel,
the additive reservoir low level is indicated by:
To p p i n g u p
The reservoir must be topped up without delay
by a CITROËN dealer or a qualified workshop.
Used products
- fixed illumination of the particle filter warning lamp, accompanied
by an audible signal,
or
do n
ot discard used oil or fluids into
sewers or onto the ground.
Take used oil to a CITR
oËn
dealer or
a qualified workshop (France) or to an
authorised waste disposal site.
av
oid prolonged contact of used oil or
fluids with the skin.
Most of these fluids are harmful to
health or indeed very corrosive.
Coolant level
The coolant level should be close
to the "MaX " mark but should never
exceed it.
When the engine is warm, the temperature of
the coolant is regulated by the fan.
Changing the coolant
The coolant does not have to be replaced at
routine services.
Fluid specification
The coolant must conform to the
manufacturer's recommendations. Top up the level when necessary.
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.
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.
Screenwash fluid level
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.

Braking
Towing a trailer increases the braking distance.
To avoid overheating of the brakes on a long
mountain type of descent, the use of engine
braking is recommended.
Ty r e s
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.
The rear parking sensors will be
deactivated automatically if a genuine
CITROËN towbar is used.
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.

I
f the warning lamp and the
STOP warning lamp come on,
stop the vehicle and switch off
the engine as soon as possible.
