Engine Immobiliser System (W/ Smart Key System) -- Precaution



1.PRECAUTIONS WHEN USING TECHSTREAM

  1. When using the Techstream to troubleshoot the smart key system: Connect the Techstream to the DLC3 while the engine switch is off, and turn a door courtesy light switch on and off at 1.5-second intervals until communication between the Techstream and vehicle begins.


2.PRECAUTIONS FOR EACH FUNCTION

  1. Precautions for the key:

    1. The key is a precision instrument. Be sure to observe the following:

    1. Do not drop or strike the key.

    2. Do not keep the key in a high temperature area for a long time.

    3. Do not use an ultrasonic washing machine to clean the key.

    4. Keep the key away from magnets or magnetized items during use.

    5. Do not attach any stickers to the key.

  2. Precautions for the engine start function:

    1. Before starting the engine, firmly depress the brake pedal until the indicator of the engine switch illuminates in green.

    2. Be sure to turn the engine switch off before disconnecting the cable from the negative (-) battery terminal. When the battery terminal is disconnected, the power source mode (off, on (ACC), on (IG)) will remain in memory. When the vehicle battery becomes discharged, be sure to remember the power source mode.

    3. After the battery is removed and reinstalled, be sure to wait 10 seconds or more before starting the engine. The engine may not start immediately after the battery is reinstalled.

  3. Precautions for the battery built into the key and the vehicle battery:

    1. When the doors are locked (locked state), signals are emitted by the vehicle at predetermined intervals. If the vehicle remains parked for a long time, the battery may become discharged. To prevent this, periodically charge the vehicle battery, or disable the smart key system.

    2. When the doors are locked (locked state), and the key remains in the door oscillator detection area, the system will maintain periodic communication with the key. If the vehicle remains parked in this state for a long time, the vehicle and key batteries may become discharged. If the vehicle is not being used, keep the key at least 2 m (6.56 ft.) away from the vehicle.
