Key Battery Replacement
If the buttons on the smart key are inoperable and the operation indi-
cator light does not flash, the battery may be dead.
Replace with a new battery before the smart key becomes unusable.
The following conditions indicate that the battery power is low: • The KEY indicator light (green) flashes in the combination meter for about 30 seconds after the engine is turned off.
• The system does not operate and the operation indicator light on the smart key does not flash when the buttons are pressed.

instruction below.
