Chevrolet Sonic: Starting the Engine

Chevrolet Sonic Owners Manual

The vehicle has a Computer-Controlled Cranking System. It assists in starting the engine and protects components. If the ignition key is turned to START and then released when the engine begins cranking, the engine will continue cranking for a few seconds or until the engine starts. If the engine does not start and the key is held in START, cranking will be stopped after 15 seconds to prevent damage. To prevent gear damage, cranking is not allowed if the engine is running. Engine cranking can be stopped by turning the ignition key to ACC/ ACCESSORY or LOCK/OFF. See Starting the Engine.
