The fuel-saving Engine Stop/Start system automatically turns off the engine, referred to as an Auto Stop, when the brake pedal is pressed and the vehicle is at a complete stop, if certain operating conditions are met. In Auto Stop mode, the tachometer will read AUTO STOP. When the brake pedal is released or the accelerator pedal is pressed, the engine will restart. After parking the vehicle and turning off the engine, the tachometer will read OFF.
