Automatic Engine Start/Stop Feature
Vehicles with eAssist have an automatic engine start/stop feature.
After the engine is started and has reached operating temperature, the auto stop feature may cause the engine to turn off when the brake pedal is applied and the vehicle comes to a complete stop. When the brake pedal is released, or the accelerator pedal is applied, the engine will restart. The engine will continue to run until the next auto stop.
To restart the engine during the auto stop, release the brake pedal or press the accelerator pedal. The engine starts immediately. The vehicle continues to run until the next stop.
AUTO STOP on the tachometer signifies that the engine is in auto stop mode. See Tachometer for more information.
A chime will sound when the driver door is opened while in auto stop mode. Remember to shift to P (Park) and turn the ignition to LOCK/OFF before exiting the vehicle.
See Starting the Engine.
