Unique Driving Characteristics AUTO-START-STOP (If Equipped) The system helps reduce fuel consumption by automatically shutting off and restarting the engine while stopped. The engine will restart automatically when you release the brake pedal. In some situations, your vehicle may restart automatically, for example: • To maintain interior comfort. • To recharge the battery. Note: Power assist steering turns off when the engine is off. WARNINGS The engine may restart automatically if required by the system. Switch the ignition off before opening the hood or performing any maintenance. Failure to do so may result in serious injuries due to automatic engine restart. Always switch the ignition off before leaving your vehicle, as the system may have turned the engine off, but the ignition will still be on and automatic restart may occur.
