Do not stop the engine while the vehicle is moving:

Stopping the engine while the vehicle is moving for any reason other than in an emergency is dangerous. Stopping the engine while the vehicle is moving will result in reduced braking ability due to the loss of power braking, which could cause an accident and serious injury.

  • If the system detects that the remaining battery power of the key is low when the ignition is switched from ON to ACC or OFF, the following is indicated.

    Replace with a new battery before the key becomes unusable.

    Refer to Key Battery Replacement (Search).

    A message is indicated in the display of the instrument cluster.

    Refer to KEY Warning Indication/Warning Light (Red) (Search).

Emergency Engine Stop

Continuously pressing the push button start or quickly pressing it any number of times while the engine is running or the vehicle is being driven will turn the engine off immediately. The ignition switches to ACC.

i-stop (Some Models)

i-stop

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

 

  • After parking the vehicle, make sure that the ignition is switched OFF. There is the possibility of the vehicle moving if the vehicle is parked while i-stop is operating.

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

    • When engine idling is stopped.

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

Engine idle stopping and restarting while vehicle is stopped

(AUTOHOLD operation turned off)

  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.

(When the vehicle is stopped by the AUTOHOLD function)

  1. Bring the vehicle to a complete stop by depressing the brake pedal first and then the clutch pedal.

  2. While depressing the clutch pedal, shift the shift lever to neutral. After releasing your foot from the clutch pedal, engine idling stops and continues to be stopped even if the brake pedal is released.

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

Engine idle stopping and restarting while driving

  1. The gear shift indicator (GSI) displays N when engine idling can be stopped while the change lever is in a position other than neutral.

  2. Depress the clutch pedal.

  3. Shift the change lever to the neutral position.

  4. Engine idling is stopped after releasing the clutch pedal.

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

Engine idle stopping and restarting while vehicle is stopped

(AUTOHOLD operation turned off and When not using Mazda Radar Cruise Control with Stop & Go function (MRCC with Stop & Go function)/Traffic Jam Assist (TJA))

  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.)

(When the vehicle is stopped by the MRCC with Stop & Go function/TJA stop hold control)

  1. When the vehicle is stopped by the MRCC with Stop & Go function/TJA, engine idling stops and continues to be stopped without depressing the brake pedal.

  2. When the accelerator pedal is depressed or the RES switch is operated, while the vehicle is stopped by the MRCC with Stop & Go function/TJA, the engine will automatically restart if the selector lever is in the D/M position (not in second gear fixed mode).

(When the vehicle is stopped by the AUTOHOLD function)

  1. When the brake pedal is depressed while the vehicle is being driven and the vehicle comes to a stop, the i-stop function will operate and continue to operate even if the brake is released (except when driving in the R or M position second gear fixed mode).

  2. The engine restarts automatically when the accelerator pedal is depressed with the selector lever in the D/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.)

(When using MRCC with Stop & Go function/TJA)

  1. Engine idling stops when the vehicle has decelerated to about 20 km/h (12 mph) or slower while in headway control using the MRCC with Stop & Go function/TJA.

  2. If it is necessary to accelerate while in headway control using the MRCC with Stop & Go function/TJA, the engine restarts automatically.

Vehicle Roll Prevention Function (Automatic transmission)

Vehicles with the i-stop function are equipped with a vehicle roll prevention function. This function prevents the vehicle from rolling, such as when releasing the brake pedal while on a slope under the following conditions:

  • While engine idling is stopped (prevents the vehicle from rolling back)

  • When the engine restarts after releasing the brake pedal (prevents the vehicle's sudden movement due to vehicle creep), sudden movement of the vehicle is prevented by controlling the brakes.

    1. Release foot from brake pedal

    2. Vehicle brake force maintained

    3. Engine restarted

    4. Acceleration

 

Do not rely completely on the vehicle roll prevention function.

  • The vehicle roll prevention function is a supplementary function which operates for a maximum of 2 seconds after releasing the brake pedal and accelerating the vehicle from an engine idling stop condition. Over reliance on the system may result in an unexpected accident if the vehicle were to suddenly accelerate. Before starting to drive the vehicle, always confirm the safety of the surroundings and operate the selector lever, brake pedal, and accelerator pedal appropriately. Note that the vehicle may move suddenly depending on the vehicle's load or if it is towing something.

  • Note that the vehicle may move suddenly after the vehicle roll prevention function is released while the vehicle is under the following conditions:

    • The selector lever is in the N position.

    • If the selector lever is shifted to the N position and the brake pedal is released while the i-stop function is operating, the brake force is gradually released. To accelerate the vehicle, release the brake pedal after the engine restarts and shift the selector lever to a position other than the N position.

Close Warning
View Warning

 

  • When the vehicle is stopped on a steep grade, the vehicle roll prevention function does not operate because engine idling is not stopped.

  • The brake pedal response may change, sound may occur from the brakes, or the brake pedal could vibrate from the operation of the vehicle roll prevention function. However, this does not indicate a malfunction.
