KEY REMINDER FUNCTION
Key reminder functions have the following 2 functions.
CAUTION:
• The above function operates when the Intelligent Key is inside the vehicle. However, there may be
times when the Intelligent Key cannot be detected, and this function will not operate when the Intelli-
gent Key is on the instrument panel, rear parcel shelf or in the glove box. Also, this system some-
times does not operate if the Intelligent Key is in the door pocket of an open door.
List of Operation Related Parts
Parts marked with × are the parts related to operation
REMOTE KEYLESS ENTRY FUNCTIONS
The Intelligent Key has the same functions as the remote keyless entry system. Therefore, it can be used in
the same manner as the keyfob by operating the door lock/unlock button.
