Auxiliary warning system - general information and component renewal
Body electrical system / Auxiliary warning system - general information and component renewal


1 Some models are fitted with an auxiliary warning system, which monitors brake lights, sidelights, dipped beam and tail lights, external temperature, and door/tailgate/ bootlid opening. An engine oil level warning light on the instrument panel is also part of the system.

2 The auxiliary warning system module and graphic warning display are combined into one unit.

Service interval reminder 3 The system also includes a service interval reminder warning light, which is illuminated if the specified mileage (or time) since the last service has been reached.

4 To reset the service interval system and turn off the light, a switch inside the glovebox must be depressed for a minimum of 4 seconds with the ignition switched on. This should be carried out by a Ford dealer if the vehicle is still in the warranty period.
