Speedometer
Indicates the current vehicle speed.
Fuel gauge
Displays approximately how much
fuel is in the fuel tank (when the
key is in the ON position). The fuel
gauge may vary slightly when the
vehicle is in motion. The ignition
should be in the OFF position while
the vehicle is being refueled. When
the gauge first indicates empty, there is a small amount of reserve fuel in
the tank. When refueling the vehicle from empty indication, the amount
of fuel that can be added will be less than the advertised capacity due to
the reserve fuel.
A minimum of six gallons must be added or removed from the fuel tank
in order for the gauge to instantaneously update. If less than six gallons
is the change, the gauge will take between five to ten minutes to update.
