Hyundai Elantra HD: Fuel gauge
The fuel gauge indicates the approximate amount of fuel remaining in the fuel tank. The fuel tank capacity is given in section 9. The fuel gauge is supplemented by a low fuel warning light, which will illuminate when the fuel tank is nearly empty.
WARNING - Fuel gauge
Running out of fuel can expose vehicle occupants to danger. You must stop and obtain additional fuel as soon as possible after the warning light comes on or when the gauge indicator comes close to the E level.
CAUTION
Avoid driving with a very low fuel level. If you run out of fuel, it could cause the engine to misfire and result in excessive loading of the catalytic converter.
