Auto Idle Stop

To help maximize fuel economy, the engine automatically stops when the vehicle comes to a stop, depending on environmental and vehicle operating conditions. The indicator (green) comes on at this time.

The environmental and vehicle conditions that impact Auto Idle Stop system operation are varied.

The engine then restarts once the vehicle is about to move again, and the indicator (green) goes off.

If the driver’s door is opened while the indicator (green) comes on, a buzzer sounds to notify you that the Auto Idle Stop function is in operation.

A message associated with Auto Idle Stop appears on the driver information interface.

The Auto Idle Stop suspend indicator comes on and a message appears on the driver information interface when the Auto Idle Stop system cannot be activated.
