Electronic Key Alarm
The electronic key alarm uses an alarm and warning messages to indicate that the electronic key has been used improperly. Take appropriate measure in response to any warning messages that are displayed. In some cases, an alarm may sound without an accompanying warning message. If so, follow the correction procedure in the table below.


*1: A message will be shown on the multi-information display in the
instrument cluster.
*2: If the engine does not start when the electronic key is inside the vehicle,
the electronic
key battery may be depleted or there may be difficulties receiving signal from
the key.
