i-stop (Some Models)

i-stop (Some Models)

The i-stop function automatically stops the engine when the vehicle is stopped at a traffic light or stuck in traffic, and then restarts the engine automatically to resume driving. The system provides improved fuel economy, reduced exhaust gas emissions, and eliminates idling noise while the engine is stopped.

Engine idle stopping and restarting

 

  • The i-stop indicator light (green) turns on under the following conditions:

    • When engine idling is stopped.

    • (Except European model)

      Engine idling stop conditions are met while the vehicle is being driven.

  • The i-stop indicator light (green) turns off when the engine is restarted.

Manual transmission

  1. Stop the vehicle by depressing the brake pedal and then the clutch pedal.

  2. While depressing the clutch pedal, shift the shift lever to the neutral position. Engine idling stops after the clutch pedal is released.

  3. The engine restarts automatically when the clutch pedal is depressed.

Automatic transmission

  1. Engine idling stops when the brake pedal is depressed while the vehicle is driven (except for driving in the R or M position second gear fixed mode) and the vehicle is stopped.

  2. The engine restarts automatically when the brake pedal is released with the selector lever in the D or M position (not in second gear fixed mode).

  3. If the selector lever is in the N or P position, the engine does not restart when the brake pedal is released. The engine restarts when the brake pedal is depressed again or the selector lever is shifted to the D, M (not in second gear fixed mode) or the R position. (For the purposes of safety, always keep the brake pedal depressed when shifting the selector lever while engine idling is stopped.)
