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.

203Practical information
The rear parking sensors will be deactivated automatically if a genuine
CITROËN towbar is used.
Driving advice
Distribution of loads
 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 per formance. Above 1 000 metres, the maximum towing load must be reduced by 10 % and so on for every 1 000 metres of altitude. Refer to the "Technical Data" section for details of the weights and towing loads which apply to your vehicle.
Side wind
 Take into account the increased sensitivity to side wind.
Cooling
Towing a trailer on a slope increases the temperature of the coolant. As the fan is electrically controlled, its cooling capacity is not dependent on the engine speed.  To lower the engine speed, reduce your speed. The maximum towing load on a long slope depends on the gradient and the ambient temperature. In all cases, pay attention to the coolant temperature.
Braking
Towing a trailer increases the braking distance.
Tyres
 Check the tyre pressures of the towing vehicle and of the trailer, obser ving the recommended pressures.
Lighting
 Check the electrical lighting and signalling on the trailer.
 If the warning lamp and the STOP warning lamp come on, stop the vehicle and switch off
the engine as soon as possible.
