The turning engine off feature recognizes when the vehicle has stopped moving and activates the engine shut-off.
The Mazda 3 Hatchback’s engine-turning off feature was created with the comfort and convenience of the driver in mind. It determines the best circumstances for engine shut-off by taking into account a number of variables, including interior and external temperatures, battery charge level, and the operation of other electrical systems. Additionally, the system offers an override option that enables the driver to momentarily turn off the feature as needed. The 2023 Mazda 3 Hatchback is an eye-catching vehicle with a plethora of features and improvements. One of this model’s main features is its ability to turn off the engine.
Turning Engine Off
WARNING
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.
- Stop the vehicle completely.
- (Manual transmission)
Shift into neutral and set the parking brake.
(Automatic transmission)
Shift the selector lever to the P position and set the parking brake. - Press the push button start to turn off the engine. The ignition position is off.
CAUTION
- When leaving the vehicle, make sure the push button start is off.
NOTE
- The cooling fan in the engine compartment could turn on for a few minutes after the ignition is switched from ON to OFF, whether or not the A/C is on or off, to cool the engine compartment quickly.
- 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 on page 6-30.
A message is indicated in the display of the instrument cluster.
Refer to KEY Warning Indication/Warning Light (Red) on page 7-34. - (Automatic transmission)
If the engine is turned off while the selector lever is in a position other than P, the ignition switches to ACC.
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
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.

The engine will restart if the brake pedal is depressed again or the selector lever is shifted to the D, M (not in second gear fixed mode), or R position. (For the purposes of safety, always keep the brake pedal depressed when shifting the selector lever.) If the selector lever is shifted from the D or M (not in second gear fixed mode) to the N or P position, and the driver’s seat belt is unfastened or the driver’s door is opened, the engine restarts.
Battery terminals have been disconnected
Engine idling may not stop right after the battery terminals have been disconnected. In addition, if the battery is replaced, the i-stop functions must be verified. Consult an Authorized Mazda Dealer.

- Indicator light
NOTE
If the engine is stopped with the i-stop function stopped, the i-stop function becomes operational again when the engine is started the next time.
Vehicle Roll Prevention Function
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.
- Release foot from brake pedal
- Vehicle brake force maintained
- Engine restarted
- Acceleration
WARNING
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.
NOTE
- 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.
i-stop Warning Light (Amber)/ i- stop Indicator Light (Green)
To ensure safe and comfortable use of the vehicle, the i-stop system constantly monitors the driver’s operations, the vehicle’s interior and exterior environment, and the operational status of the vehicle, and uses the i-stop warning light (amber) and i-stop indicator light (green) to inform the driver of various cautions and warnings.
NOTE
On vehicles equipped with the center display, the i-stop operation status is displayed in the fuel efficiency monitor display.
Refer to the Fuel Efficiency Monitor section in the Mazda Connect Owner’s Manual.
