Monitoring
Warning lamps
When the engine is running or the vehicle is
being driven, the illumination of one of the following warning lamps indicates a fault which
requires action on the par t of the driver.
Any fault resulting in the illumination of a warning lamp must be investigated fur ther byreading the associated message in the multifunction screen.If you encounter any problems, do not hesitate to contact a CITROËN dealer or a qualified
workshop.

Warning lampis onCauseAction/Observations
STOPfixed, alone or associated with another warning lamp, accompanied by anaudible signal and a message on thescreen. Illumination o
f the warning lamp is
associated with a serious brakingsystem or engine coolant temperature
problem.
Stop as soon as it is safe to do so as the engine may cut out when driving.
Park, switch off the ignition and call a CITROËN dealer
or a qualified workshop.
Servicetemporarily. Minor problems have occurred for
which there is no specific warning lamp. Identi
fy the problem by reading the message shown in
the screen, such as, for example:
- the en
gine oil level,
- the screenwash level,
- the remote control batter
y,
- saturation of the par ticle emission filter on Diesel
vehicles (see "Checks - § particle emissionsfilter").
For any other faults, contact a CITROËN dealer or a
qualified workshop.

fixed. The emission control system has a fault.The warning lamp should go off when the engine is started.
If it does not go off, contact a CITROËN dealer or qualified workshop without delay.
Low fuel levelfixed. When it first comes on there remains approximately 5 litres offuelin thetank. You must refuel as soon as possible to avoid runnin
gout 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 coolanttemperaturefixed 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 toppingup 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 themaximum 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 "MAX" mark.

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 plain water.

Take care when carrying out checks under the bonnet as some parts of theengine can be very hot (risk of burns).

Coolant level
Top up the level when necessary.
Th
e 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 particle emission filter, the fan may operate after
the vehicle has been switched off, even if
the en
gine 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.

The rear parking sensors will be deactivated automatically if a genuineCITROËN towbar is used.
Cooling
Towing a trailer on a slope increases the
temperature of the coolant.
As the fan is electrically controlled, its coolingcapacity is not dependent on the engine speed. )To 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.
Braking
To w i ng a trailer increases the braking distance.
To avoid overheating of the brakes on a longmountain type of descent, the use of engine braking is recommended.

Tyres
)
Check the tyre pressures of the towing
vehicle and of the trailer, obser ving the
recommended pressures.

Lighting
)
Check the electrical lighting and signallingon the trailer.
)
If the warning lamp and the
STOPwarning lamp come on,
stop the vehicle and switch off
the engine as soon as possible.

RACING towbar

Your vehicle cannot be fitted with a towbar. The space occupied by thesport diffuser prevents this.
