The widely popular Ford Mondeo also know as the Ford Fusion was first manufactured in 1993 and is now currently on the 5th generation. With many years of upgrades and improvements, the Ford Mondeo is considered dependable and reliable. With most modern cars however, if a problem occurs, you’ll know about it via a dashboard warning light.
The onboard computer in a car, called the ECU (Engine Control Unit) reads various sensor located around a vehicle. When the ECU detects a fault, a dashboard warning light is triggered. The colour of the light often determines how serious or urgent the fault it is.
Blue and green symbols are used to represent and active system such as lights. Amber / orange / yellow represent either a maintenance reminder or a minor fault. Red symbols are much more urgent and demand immediate attention. In some instances a red symbol that’s ignored may result in expensive damage to the vehicle, or potential risk to vehicle occupant safety.

Ford Mondeo / Fusion Engine Fault Light
Often referred to the MIL (Malfunction Indicator Lamp), ‘check engine light’, or ‘engine management light’, this symbol illuminates when the OBD (On Board Diagnostics system) has detected a malfunction of the vehicle emissions control system. If the light is flashing, this indicates an engine misfire and may damage the catalytic converter due to excessive exhaust emission temperatures. There is a risk of fire. In this instance (flashing light), drive carefully and seek immediate assistance from Ford Engineer. For further help, see why is the engine management light on?
Ford Mondeo / Fusion Stability Control (ESP) Warning Light
This system also known as ESP (Electronic Stability Program) makes the vehicle more stable when it starts to slide away from the intended path. This is done by braking individual wheels and reducing engine power as required. Traction control is also a feature of this system to prevent wheel spin which aids in pulling away on slippery or loose road surfaces. The stability control light will flash when the system in engaged – reduce speed and drive carefully. If it remains illuminated or does not illuminate when you switch the ignition on, this indicates a malfunction.
Ford Mondeo / Fusion Low Fuel Warning Light
This low fuel warning light will come on when there’s approximately 50 miles remaining. This is an estimate and is relative to driving style and conditions. It’s advised to refuel as soon as possible. Running out of fuel can damage the engine. Any damage obtained as a result of running out of fuel is not covered under manufacturers warranty.
Ford Mondeo / Fusion Seat Belt Warning Light
The seat belt warning light illuminates along with an audible sound when the front safety belts have not been fastened and the vehicle exceeds a relatively low speed. If you do not fasten your seat belt, the safety warning alert will turn off after approximately five minutes. If you are experiencing issues will the light failing to go out, see seat belt light stays on.
Ford Mondeo / Fusion DPF Warning Light
The DPF (Diesel Particulate Filter) light comes on indicating that the DPF requires cleaning. Not all models of the Ford Mondeo have a DPF warning light, instead you may receive message Diesel Filter Overloaded. In either case, the regeneration process is usually automatic, though under certain conditions driver support may be required. This is more likely if you drive for only short journeys and the system may require driver support at approximately every 500 miles. To assist the process, drive at 50 mph (80 km/h) for 25 miles (40 kilometres) using the lowest possible gear.
