In this car the A/C compressor is electric and can run off the hybrid battery. The engine will only start again either when the vehicle moves, or when the Hybrid battery charge level drops below the threshold and it can no longer power the systems.@ishan.fdoThe engine turns off when you become stationary in traffic if the hybrid battery has enough charge. When you lift your foot off the break the engine switches back on automatically. This is called 'Auto Stop'.When you are on the move, the petrol engine (which is a 1300cc 3 stage i-VTEC) always runs. When you require more power (i.e. accelerating), the electric motor spins and adds 20 horsepower to ease the engine's burden, saving fuel, and it gives you a feeling of 'boost' when driving. Although the engine would never turn off while the car is on the move,  it has VCM (Variable Cylinder Management), which permits deactivation of all four cylinders at certain cruise speeds which increases fuel efficiency.The plus side of this system is that the car would never become stationary even if the hybrid battery totally goes dead . You could technically remove the H/V battery and still the car would run using the petrol engine. but with less horsepower at its disposal.</blockquote>
