This section describes the operation of the back door opener switch. The operation of the back door request

tion"

. 

• The back door opener function can open the back door by pressing the back door opener switch while carry-

door) and inside key antenna and transmits the request signal to the Intelligent Key. And then, check that the
Intelligent Key is near the back door.

• If the Intelligent Key is within the outside key antenna detection area, it receives the request signal and

transmits the key ID signal to the BCM via remote keyless entry receiver.

• BCM receives the key ID signal and compares it with the registered key ID.
• BCM open the back door and sounds Intelligent Key buzzer warning at the same time as a reminder.

If the following conditions are satisfied, the back door can be opened. 
• Back door is closed
• Ignition switch is in off position
• Intelligent Key is out of key slot
• Intelligent Key is outside of vehicle
• Intelligent Key is within out side key antenna detection area

OUTSIDE KEY ANTENNA DETECTION AREA

The outside key antenna detection area of back door open function
is in the range of approximately 80 cm (31.50 in) surrounding the
back door opener switch (1). However, this operating range depends
on the ambient conditions.
