Low Fuel Warning Indicator
WARNING: This page is about a different car, the 2007 Mercury Mariner and 2007 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
The low fuel warning indicator is controlled by the instrument cluster and uses hardwired fuel level data from the fuel pump module. When the fuel level drops below a pre-determined level, the instrument cluster illuminates the low fuel warning indicator (Escape, Mariner) or a display in the message center (Hybrid).
