When you switch on the ignition, the
indicator lamp comes on briefly to
confirm that the system is operational.
Once the indicator lamp stays on
continuously, there are still approx.
2.1 gallons (8 liters) of fuel in the fuel
tank.

If the tilt of the vehicle varies (extended
driving in mountainous areas, for
example), the needle may fluctuate
slightly.
Please refuel early, since driving
to the last drop of fuel can result in
damage to the engine and/or catalytic
converter.< 36mus729
