Start/Stop Engine
Ignition Switch
Push Button Start Positions
The system operates only when the key is within operational range.
Each time the push button start is pressed, the ignition switches in the order of off, ACC, and ON. Pressing the push button start again from ON switches the ignition off.
-
The engine starts by pressing the push button start while depressing the clutch pedal (manual transmission) or the brake pedal (automatic transmission). To switch the ignition position, press the push button start without depressing the pedal.
-
Do not leave the ignition switched ON while the engine is not running. Doing so could result in the battery going dead. If the ignition is left in ACC (For automatic transmission, the selector lever is in the P position, and the ignition is in ACC), the ignition switches off automatically after about 25 minutes.
Off
The power supply to electrical devices turns off and the push button start indicator light (amber) also turns off.
In this position the steering wheel is locked. (Some Models)
Before leaving the driver's seat, always switch the ignition off, set the parking brake, and make sure the selector lever is in P (automatic transmission) or in 1st gear or R (manual transmission):
Leaving the driver's seat without switching the ignition off, setting the parking brake, and shifting the selector lever to P (automatic transmission) or to 1st gear or R (manual transmission) is dangerous. Unexpected vehicle movement could occur which could result in an accident.
In addition, if your intention is to leave the vehicle for even a short period, it is important to switch the ignition off, as leaving it in another position will disable some of the vehicle's security systems and run the battery down.
(Locked steering wheel) (Some Models)
If the push button start indicator light (green) is flashing and the beep sound is heard, this indicates that the steering wheel is not unlocked. To unlock the steering wheel, press the push button start while moving the steering wheel left and right.
ACC (Accessory)
Some electrical accessories will operate and the indicator light (amber) illuminates.
In this position the steering wheel is unlocked. (Some Models)
The keyless entry system does not function while the push button start has been pressed to ACC, and the doors will not lock/unlock even if they have been locked manually.
ON
This is the normal running position after the engine is started. The indicator light (amber) turns off. (The indicator light (amber) illuminates when the ignition is switched ON and the engine is not running.)
Some indicator lights/warning lights should be inspected before the engine is started (Search).
When the push button start is pressed to ON, the sound of the fuel pump motor operating near the fuel tank can be heard. This does not indicate an abnormality.
Starting the Engine
Radio waves from the key may affect medical devices such as pacemakers:
Before using the key near people who use medical devices, ask the medical device manufacturer or your physician if radio waves from the key will affect the device.
-
The key must be carried because the key carries an immobilizer chip that must communicate with the engine controls at short range.
-
The engine can be started when the push button start is pressed from off, ACC, or ON.
-
The push button start system functions (function which can start the engine by only carrying the key) can be deactivated to prevent any possible adverse effect on a user wearing a pacemaker or other medical device. If the system is deactivated, you will be unable to start the engine by carrying the key. Consult an expert repairer, we recommend an Authorised Mazda Repairer for details. If the push button start system functions have been deactivated, you can start the engine by following the procedure indicated when the key battery goes dead.
Refer to Engine Start Function When Key Battery is Dead (Search).

(Manual transmission)
The light flashes when the shift lever is shifted to a position other than the neutral while engine idling is stopped to notify the driver that engine idling is stopped.
By depressing the clutch pedal, the engine restarts automatically and the light turns off.
-
(European model)
-
The light flashes when the driver's door is opened while engine idling is stopped to notify the driver that engine idling is stopped. It turns off when the driver's door is closed.
-
If the engine is restarted due to low battery voltage while the engine idling is stopped, the i-stop indicator light (green) in the instrument cluster flashes for about 3 seconds. However, when the engine is restarted automatically after operating the retractable hardtop switch, the i-stop indicator light (green) in the instrument cluster does not flash.
-
-
(Except European model)

If the engine is stopped with the i-stop function cancelled, the i-stop function becomes operational when the engine is started the next time.
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 or the automatic transmission.
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 four 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.
-
-
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.
