Fuel gauge

The fuel gauge displays the amount of fuel remaining on a scale of 0 to 1/1. The

saddle-shaped fuel tank consists of a main tank compartment and a sub-tank

compartment. When the fuel level drops to approximately 2.9 gal. (11 L, 2.4 Imp. gal.)

between both compartments, the bar display will blink in amber to inform the driver

that the remaining fuel level is low. In this state, the remaining amount of fuel is directed

into the main tank compartment in order to ensure a stable supply of fuel to the engine

even under high cornering G-loads.

Blinks when remaining fuel drops to approx.

The main tank compartment and sub-tank compartment each have their own

individual sender gauges to monitor the fuel levels. The ECU calculates the total

amount of fuel remaining from both of these sensors and informs the driver using

the fuel gauge. The ECU digitally processes the fuel level data in order to display a

clear and accurate fuel level even when the fuel level ²uctuates under high cornering

G-loads.
