Information

If the Auto Stop ( ) indicator on the instrument cluster is white, the ISG system does not meet the above conditions and is not active. If the Auto Stop ( ) indicator is yellow, have the system inspected by an authorized HYUNDAI dealer.

Auto Stop

When ISG is enabled, the engine stops automatically when both of the following occur:

1. Vehicle speed decreases to 0 km/h (complete stop condition).

2. Brake pedal is depressed and the transmission is in D (Drive) or N (Neutral).

The Auto Stop ( ) indicator illuminates green on the instrument cluster when the engine stops.

Information

Idle stop cannot be repeated until the vehicle speed exceeds 3 mph (5 km/h) and then comes to a complete stop again.

In Auto Stop mode, if the hood is open, the ISG system is deactivated.

When the system is deactivated, the ISG OFF button indicator illuminates, and the message "Auto Stop disabled. Shift to P or N and start the engine manually" appears on the cluster display with a warning chime.

In this case, depress the brake pedal and restart the engine manually.

Auto Start

When the ISG stops the engine automatically, the engine restarts if:

- The brake pedal is released. - You release the brake pedal and then depress the accelerator pedal while Auto Hold is activated. - You shift from N (Neutral) or D (Drive) to R (Reverse) or P (Park) while depressing the brake pedal. - You shift from N (Neutral) to D (Drive) while depressing the brake pedal.

The Auto Stop ( ) indicator turns white on the instrument cluster when the engine restarts.

Messages on the Cluster Display

Auto Stop disabled. Shift to P or N and start the engine manually.

When the system is deactivated, the ISG OFF button indicator illuminates and a message appears on the cluster display with a warning chime if:

- The hood is open.
- The ISG system is not operating normally.

In this case, depress the brake pedal and restart the engine manually. For your safety, restart the vehicle in P (Park) position.

Depress the brake pedal to start automatically.

When shifting from N (Neutral) to R (Reverse), D (Drive), or manual shift mode without depressing the brake pedal, a message appears on the cluster display. To activate auto start, depress the brake pedal.

Auto Stop Elapsed Time

The AUTO STOP display shows the elapsed time of engine idle stop and the Drive system.

You can check the elapsed AUTO STOP time in the trip computer mode on the instrument cluster.
