Operation Check

  1. SMART ACCESS SYSTEM WITH PUSH-BUTTON START OPERATION INSPECTION 
    1. Check the entry unlock function
      1. Use the wireless lock operation to lock the doors With the key in your possession, touch a door's outside handle (touch sensor) and check that the door unlocks
    2. Check the entry unlock operation's detection area
      1. Step 1 Hold the key at the same height as the door's outside handle (approximately 0 8m (2 62 ft)) Pay attention to the direction of the key in the illustration
      2. Step 2 Check that when the key is brought within 0 7 to 1 0 m (2 30 to 3 28 ft) of the vehicle, the system enters unlock standby mode

        HINT

        Unlock standby mode is signified by the key's red LED illuminating

      3. Step 3 After the system enters unlock standby mode, touch the outside handle's sensor within 3 seconds Check that the door unlocks
        NOTE: The key may not be able to communicate with the system within a 0.2 m (0.656 ft.) radius of each outside handle.

      4. Step 4 Repeat step  2 and step  3 for the remaining doors
      5. Step 5: Inspect the door electrical key oscillator's response sensitivity Wear protective gloves, set the system to unlock standby mode, and check that touching the inner side of the outside handle (the highlighted area in the illustration) with your finger causes the door to unlock
        NOTE: When touching the highlighted area, tapping too quickly or having extended contact may not trigger the sensor. In such a case, the door will not unlock.
      6. Step 6. Repeat step  5 for the remaining doors.
    3. Check the entry lock function
      1. Step 1 Close all of the vehicle's doors. With the key in your possession outside of the vehicle, check that pressing the lock switch locks the doors

        HINT

        • When pressing the lock switch, hold the electrical key transmitter about 1 m (3.28 ft) above the ground and about 0 3 m (0 984 ft.) away from the vehicle as shown in the illustration
        • Due to the key being unable to communicate with the system within a 0 2 m (0 656 ft.) distance from the outside handle, do not press the lock switch with the same hand that is holding the key The doors may not lock.
        • If the key lock-in prevention function buzzer sounds, radio waves from the indoor electrical key oscillator may be leaking from the vehicle Perform the same check for the front passenger side and rear doors.

      2. Step 2. Repeat step  1 for the remaining doors
    4. Check the entry luggage compartment door open function.
      1. Close the luggage compartment door With the key in your possession, check that pressing the luggage door opener switch opens the luggage compartment door.
      2. Inspect the entry luggage compartment door open operation's detection area Hold the key at the same height as the luggage door opener switch (approximately 0 8 m (2 62 ft)) aligning it with the center of the rear of the vehicle Pay attention to the direction of the key shown in the illustration Check that when the key is brought within 0 7 to 1 0 m (2 30 to 3 28 ft) of the vehicle, pressing the luggage door opener switch opens the luggage compartment door.

    5. Check the entry ignition function
      1. When the engine is off

        With the key in your possession and the brake pedal depressed, check that pressing the engine switch releases the steering wheel lock and starts the engine

        HINT

        The engine can be started only when the engine switch indicator illuminates in green

      2. When the engine is running

        With the key in your possession, check that pressing the engine switch stops the engine and activates the steering wheel lock

        HINT

        The shift lever must be in P to be able to stop the engine

      3. Inspect the entry ignition operation's detection area (front seat) Pay attention to the direction of the key in the illustration When the key is in either of the 2 locations in the illustration, check that the engine can start
        NOTE: The engine cannot be started when the key is on the instrument panel or rear package tray, or in the glove box.

    6. Check the key lock-in prevention function (for luggage compartment)
      1. Place the key in the luggage compartment with all doors locked Check that 1) closing the luggage compartment door triggers the key's wireless buzzer (which lasts approximately 2 seconds), and 2) pressing the luggage door opener switch opens the luggage compartment door
      2. Inspect the key lock-in prevention's detection area Pay attention to the direction of the key shown in the illustration When the key is in either of the 2 locations in the illustration, check that 1) closing the luggage compartment door sounds the wireless buzzer, and 2) pressing the luggage door opener switch opens the luggage compartment door
        NOTE: If the key is inside a metal storage item, such as a metal briefcase or metal box, the key will not be able to be detected by the system.

  2. KEY DIAGNOSTIC MODE 

    HINT

    Key diagnostic mode checks if the electrical key transmitter within a selected oscillator/amplifier detection area is operating normally The results are output through the wireless door lock buzzer
