started.
If it does not go off, contact a CITROËN dealer or

flashing. The engine management system has
a fault. Risk of destruction of the catalytic conver ter.
Have it checked by a CITROËN 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) or
46 litres (Diesel); depending on version: approximately
30 litres (petrol or Diesel).
Never continue to drive until you run out of fuel as
this could damage the emission control and injection
systems.
Maximum coolant
temperature
fixed red. 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 CITROËN dealer or
qualified workshop.

With the engine running, when the needle is:
- in zone A
, the temperature is correct,
- in zone B
, the temperature is too high;
the central STOP
warning lamp and the
maximum temperature warning lamp 1
come on in red, accompanied by an audible
signal and a message in the multifunction
screen.
You must stop as soon as it is safe to do so.
Wait a few minutes before switching off the
engine.
Contact a CITROËN dealer or a qualified
workshop.
Coolant temperature indicator
After driving for a few minutes, the temperature
and pressure in the cooling system increase.
To top up the level:
)
wait for the engine to cool down,
)
unscrew the cap by two turns to allow the
pressure to drop,
)
when the pressure has dropped, remove
the cap,
)
top up the level to the "MA X" mark.

Vent ilat ion
Air intake
The air circulating in the passenger compar tment
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:
- direct arrival in the passenger compartment
(air int ake),
- passage through a heating circuit (heating),
- passage through a cooling circuit (air
conditioning).
The temperature control enables you to obtain
the level of comfor t required by mixing the air of
the various circuits.
The air distribution control enables you to
diffuse the air in the passenger compar tment
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. Depending on the model, the functions
offered are:
- the level of comfor t required,
- air flow,
- air distribution,
- demisting-defrosting,
- manual or digital air conditioning controls.
Air distribution
1.
Windscreen demisting-defrosting vents.
2.
Front side window demisting-defrosting
vents.
3.
Side adjustable air vents.
4.
Central adjustable air vents.
5.
Air outlets to the front footwells.
6.
Air outlets to the rear footwells.

Changing the coolant
The coolant does not have to be changed.
Fluid specifi cation
The coolant must conform to the
manufacturer's recommendations.
Screenwash fluid level
Fluid specifi cation
For optimum cleaning and to avoid freezing,
this fluid must not be topped up or replaced
with water.
Take care when carrying out checks
under the bonnet as some parts of the
engine can be very hot (risk of burns).
Coolant level
Top up the level when necessary.
The coolant level should be close
to the "MA X" mark but should never
exceed it.
When the engine is warm, the
temperature of the coolant is regulated by the
fan. This can operate with the ignition off.
On vehicles which are fitted with a par ticle
emission filter, the fan may operate after
the vehicle has been switched off, even if
the engine is cold.
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.
