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 transaxle) or the brake pedal (automatic transaxle). 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 transaxle, 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.
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 transaxle) or in 1st gear or R (manual transaxle):
Leaving the driver's seat without switching the ignition off, setting the parking brake, and shifting the selector lever to P (automatic transaxle) or to 1st gear or R (manual transaxle) 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)
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.
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).
(SKYACTIV-G 2.0, SKYACTIV-G 2.5)
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).
-
After starting a cold engine, the engine speed increases and a whining sound from the engine compartment can be heard.
This is for improved exhaust gas purification and does not indicate any parts defect.

Verify that the KEY indicator light (green) (if equipped) in the instrument cluster and the push button start indicator light (green) illuminate.
-
If the push button start indicator light (green) flashes, make sure that the key is being carried (for vehicles with a type A instrument cluster (Search), messages are displayed in the instrument cluster).
-
If the push button start indicator light (green) flashes with the key being carried, touch the key to the push button start and start the engine (for vehicles with a type A instrument cluster (Search), messages are displayed in the instrument cluster). Refer to Engine Start Function When Key Battery is Dead (Search).
If the KEY warning light (red) illuminates, or the push button start indicator light (amber) flashes, this could indicate a problem with the engine starting system. This may prevent the engine from starting or from switching the ignition to ACC or ON (for vehicles with a type A instrument cluster (Search), messages are displayed in the instrument cluster). Have your vehicle inspected at an expert repairer, we recommend an Authorised Mazda Repairer as soon as possible.
-
Under the following conditions, the KEY warning light (red) flashes after the push button start is pressed. This informs the driver that the push button start will not switch to ACC, even if it is pressed from off (for vehicles with a type A instrument cluster (Search), messages are displayed in the instrument cluster).

(Forced engine starting method)
If the KEY warning light (red) illuminates, or the push button start indicator light (amber) flashes, this could indicate that the engine may not start using the usual starting method (for vehicles with a type A instrument cluster (Search), messages are displayed in the instrument cluster). Have your vehicle inspected at an expert repairer, we recommend an Authorised Mazda Repairer as soon as possible. If this occurs, the engine can be force-started. Press and hold the push button start until the engine starts. Other procedures necessary for starting the engine, such as having the key in the cabin, and depressing the clutch pedal (manual transaxle) or the brake pedal (automatic transaxle) are required.
-
When the engine is force-started, the KEY warning light (red) (if equipped) remains illuminated and the push button start indicator light (amber) remains flashing.

-
(SKYACTIV-G 2.0, SKYACTIV-G 2.5)
-
Whether the engine is cold or warm, it should be started without the use of the accelerator.
-
If the engine does not start the first time, refer to Starting a Flooded Engine under Emergency Starting. If the engine still does not start, have your vehicle inspected by an Authorised Mazda Repairer (Search).
