The fuel gauge unit consists of a float and a potentiometer whose resistance varies depending
on movement of the float. It is located inside the fuel tank and forms an integral part of the fuel
pump. The fuel gauge indicates the fuel level in the tank even when the ignition switch is in the
LOCK position.

All models are equipped with two fuel level sensors. These sensors are installed in the fuel tank,
one on the right side and the other on the left side. Two sensors are necessary because the fuel
tank is divided into main and sub tank compartments.
