Some models have a low fuel level sensor
and warning light that illuminates when there
is less than about 1/5 of a tank of fuel
remaining. The system uses the same bulb as
the brake light failure indicator. The sensor is
mounted in the fuel tank. If the warning light
does not illuminate correctly, replace the
sensor; see
