STOP AND START SYSTEM PRECAUTION


  1. PRECAUTIONS WHEN INSPECTING STOP AND START SYSTEM

    Note

    When the audio and visual system volume is high, a fail-safe function may operate in order to maintain the operation of stop and start control. The fail-safe function is canceled when the ignition switch is turned off. Using the same power source for the audio and visual system and other systems allows the fail-safe functions to operate more precisely.

  2. PRECAUTIONS AFTER LEAVING VEHICLE FOR A LONG TIME

    Tech Tips

    If the vehicle has not been driven for a long time, the battery charge will be low and stop and start control operation will be prohibited. In this case, recharge the battery, initialize the integrated current value* and drive the vehicle until refresh charge is completed and stop and start control operation is permitted (approximately 15 to 40 minutes).

    *: Use the GTS to perform Integrated Current Value Initialization Click here.

  3. PRECAUTIONS WHEN CONNECTING/DISCONNECTING CABLE TO/FROM NEGATIVE BATTERY TERMINAL

    Tech Tips

    If the cable is disconnected from the negative (-) battery terminal, stop and start control is prohibited until refresh charge is completed. After connecting the cable, drive the vehicle until refresh charge is completed and stop and start control is permitted (approximately 15 to 40 minutes).


    1. If power is not supplied to the audio & visual system when the ignition switch is ON for the first time after the battery has been reconnected, DTC B22C0 will be stored. Perform either of the following operations:


      1. Turn the ignition switch from on to off twice.

      2. After turning the ignition switch from on to off, clear the DTCs.

  4. PRECAUTIONS AFTER CHARGING BATTERY

    Tech Tips

    If stop and start system control has been prohibited due to low battery charge, first charge the battery and then using the GTS, initialize the integrated current item Click here.

    If the Data List item "Integrated Current" indicates 0 or more, initialization is not necessary.

  5. IF THE ENGINE FAILS TO RESTART FROM IDLING STOP

    Note

    If the engine fails to restart when stopped by stop and start control, the brake actuator may be activated.

    Brake actuator condition:


    • When the engine fails to restart from stopping by stop and start control.

    • When the brake booster vacuum is insufficient.

    • When the vehicle speed is 3 km/h or higher and the brake pedal is depressed*.

    *: When the engine is not running.

    Tech Tips


    • When the engine fails to restart when stopped by stop and start control and the brake booster vacuum is deficient, the brake actuator is activated to ensure the braking force.

    • When the brake actuator is activated, sound and vibration may be generated. This is not due to malfunction of the stop and start system or the vehicle.

  6. WHEN THE ENGINE STOP AND START ECU AND THE STARTER ASSEMBLY ARE REPLACED

    Note


    • When the engine stop and start ECU is replaced, it is necessary to read the number of starter operation before the replacement, and to store this number in the new engine stop and start ECU. Moreover, initialization/learning of information for the air conditioner and initialization/learning of information for the deceleration sensor 0 point learning are also required Click here.

    • When the starter assembly is replaced, the number of starter operations stored in the engine stop and start ECU must be reset Click here.

  7. NOTE REGARDING PROHIBITION OF FOUR-WHEEL TOWING TRACTION

    Note

    When towing the vehicle, its front wheels or four wheels must be lifted.

    Tech Tips

    When the vehicle is towed while its four wheels touch the ground, the stop and start system may be impaired or damaged.
