    2. Step 2: Check that when the key is brought within 0.7 to 1.0 m (2.3 to 3.3 ft.) of the vehicle, the system enters unlock standby mode.

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

    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.

    2. Step 2: Inspect the entry lock operation's detection area and the indoor electrical key antenna for wave leaks. Hold the key at a height of 1 m (3.3 ft.)

Check that when the key is approximately 0.3 m (0.9 ft.) from the vehicle and the lock switch is pressed, the front doors lock and the warning buzzer (for when the key is forgotten) does not sound. If the warning buzzer sounds, the indoor electrical key antenna may have a wave leak.

      Due to the key being unable to communicate with the system within a 0.2 m (0.6 ft.) distance from the outside handle, do not press the lock switch with the same hand that is holding the key. The doors will not lock.
    3. Step 3: Repeat step 1 and step 2 for the remaining doors.
