31Monitoring
Warning lamps
When the engine is running or the vehicle is being driven, the switching on 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 switching on of a warning lamp must be investigated fur ther by reading the associated message on the multifunction screen. If you encounter any problems, do not hesitate to contact a CITROËN dealer.
Warning lampis onCauseAction/Obser vations
STOP fixed, alone or associated with another warning lamp, accompanied by an audible signal and a message on the screen.
Illumination of the warning lamp is associated with a serious braking system or engine coolant temperature fault.
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.
Ser vice
temporarily. A minor fault has occurred for which there is no specific warning lamp. Identify the fault by reading the message shown onthe screen, such as, for example:
- the engine oil level, - the screenwash level, - the remote control battery, - saturation of the par ticle emission filter (Diesel). For any other faults, contact a CITROËN dealer.
fixed. A major fault has occurred for which there is no specific warning lamp. Identify the fault by reading the message shown onthe screen and contact a CITROËN dealer.

33Monitoring
Warning lampis onCauseAction/Obser vations
Engine autodiagnosis system
fixed. The emission control system has a
fault.
This lamp should switch off when the engine is star ted.
If it does not switch off, contact a CITROËN dealer urgently.
flashing. The engine management system has a fault. Risk of destruction of the catalytic conver tor. Have it checked by a CITROËN dealer.
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 48 litres (Diesel). Never continue to drive until you run out of fuel a s 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.

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 light up in red, accompanied by an audible signal and a message on the multifunction screen. You must stop as soon as it is safe to do so. Wait a few minutes before switching off the engine. Consult a CITROËN dealer.
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 allowthe pressure to drop,  when the pressure has dropped, remove the cap,  top up the level to the "MA X" 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 water.
Take care when carrying out checks under the bonnet as some par ts 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.
