LED Fuel Gauge
See Figure 2. The fuel gauge has seven warm red LEDs which indicate the amount of fuel in the tank. Refer to Table 1.
NOTE
  • The fuel gauge is mirror glass. Recommended cleaning is with glass cleaner. Any type of abrasive chrome cleaner could damage the surface and damage surrounding painted surfaces.
  • The fuel gauge is equipped with a light-sensitive sensor. The sensor causes the fuel gauge to illuminate brighter in lighted conditions.
  • When the fuel tank has less than one gallon (3.8 liters) of fuel remaining, the low fuel lamp lights in the speedometer.
  • See Figure 2. The gas pump icon on the LED fuel gauge is not a low fuel warning lamp. It will be illuminated at all times when the ignition/headlamp key switch is in the IGNITION position.
