Start/Stop Engine

Engine Start Function When Key Battery is Dead

 


When starting the engine by holding the transmitter over the push button start due to a dead key battery or a malfunctioning key, be careful not to allow the following, otherwise the signal from the key will not be received correctly and the engine may not start.

  • Metal parts of other keys or metal objects touch the key.

  • Spare keys or keys for other vehicles equipped with an immobilizer system touch or come near the key.

  • Devices for electronic purchases, or security passage touch or come near the key.

If the engine cannot be started due to a dead key battery, the engine can be started using the following procedure:

  1. Continue to depress the brake pedal firmly until the engine has completely started.

  2. (Manual transmission)

    Continue to depress the clutch pedal firmly until the engine has completely started.

  3. Verify that the push button start indication light (green) flashes.

  4. Touch the push button start using the backside of the key (as shown) while the push button start indicator light (green) flashes.

     

     


    When touching the push button start using the backside of the key as shown in the illustration, touch the push button start with the lock switch side of the key facing up.

  5. Verify that the push button start indicator light (green) turns on.

  6. Press the push button start to start the engine.

     


    • The engine cannot be started unless the clutch pedal is fully depressed (manual transmission) or the brake pedal is fully depressed (automatic transmission).

    • If there is a malfunction with the push button start function, the push button start indicator light (amber) flashes. In this case, the engine may start, however, have the vehicle checked at an expert repairer, we recommend an Authorised Mazda Repairer as soon as possible.

    • If the push button start indicator light (green) does not illuminate, perform the operation from the beginning again. If it does not illuminate, have the vehicle checked at an expert repairer, we recommend an Authorised Mazda Repairer.

    • To switch the ignition position without starting the engine, perform the following operations after the push button start indicator light (green) turns on.

      1. Release the clutch pedal (manual transmission) or brake pedal (automatic transmission).

      2. Press the push button start to switch the ignition position. The ignition switches in the order of ACC, ON, and off each time the push button start is pressed. To switch the ignition position again, perform the operation from the beginning.

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.)
