If there is only a small amount of fuel, the hybrid system may not be able to start. (The minimum amount of fuel to add to make the low fuel level warning light go out is about 2.6 gal. [10 L, 2.1 Imp.gal.], when the vehicle is on a level surface. This value may vary when the vehicle is on a slope.) n Hybrid battery (traction battery) The hybrid battery (traction battery) has a limited service life.
