STOP AND START SYSTEM PRECAUTION


  1. EXPRESSIONS OF IGNITION SWITCH

    Tech Tips

    The type of ignition switch used on this model differs depending to the specifications of the vehicle.

    The expressions listed in the table below are used in this section.

    Expression Ignition Switch (Position) Engine Switch (Condition)
    Ignition switch off LOCK Off (Lock)
    Ignition switch ACC ACC On (ACC)
    Ignition switch ON ON On (IG)
    Engine Start START On (Start)

  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 stop and start control operation is permitted (approximately 15 to 40 minutes).

    *: Disconnect the cables from the battery, wait for 30 seconds or more and then reconnect the cables.

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

    Tech Tips

    When the cable is disconnected from the negative (-) battery terminal, stop and start control is prohibited for a certain amount of time. After connecting the cable, drive the vehicle until stop and start control is permitted (approximately 15 to 40 minutes).

  4. PRECAUTIONS AFTER CHARGING BATTERY

    Tech Tips

    If the battery is charged with the cables connected after the stop and start control has been prohibited due to low battery charge, perform the integrated current value initialization using the GTS.

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

  5. POINTS TO BE NOTED 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.

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

  6. POINTS TO BE NOTED IF THE ENGINE FAILS TO RESTART FROM IDLING STOP

    Note

    In case that the engine fails to restart from engine stop due to stop and start control, since the brake assist control becomes active, there may be sound from the operation of the brake assist control, and vehicle vibration may be generated.

    Brake actuator condition:


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

    • When the brake negative pressure is deficient.

    • 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 from stopping by stop and start control and the brake negative pressure is deficient, the brake actuator is activated to ensure the braking force.

    • These are due to the activation of the brake assist control, and not due to malfunction of the stop and start system and the vehicle.

  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.
