28. Fuel Gauge
Shows level of fuel in tank when ignition switch is in the
ON position.
29. Low Fuel Warning Light
This light will illuminate when the pointer is be-
tween "E" and 1/8 indication mark (approximately
15% of tank volume) on the fuel gauge. When the
fuel gauge pointer is on "E" (equivalent to Distance To
Empty [DTE] = 0 on the overhead console, if so
equipped) there is reserve fuel capacity, which corre-
sponds to approximately 8% of tank volume. This reserve
capacity was put in place to prevent the likelihood of
customers running out of fuel when operating at maxi-
mum load conditions in areas where there are not many
fuel stations.
30. CRUISE Indicator Light
This light will illuminate when the electronic
speed control system is turned on.
