CAUTION:
The above function operates when the Intelligent Key is inside the vehicle. However, there are cases
that Intelligent Key cannot be detect ed and this function will not operate when Intelligent Key is on the
instrument panel, rear parcel shelf, or in the gl ove box. Also, this system sometimes does not operate
if the Intelligent Key is in th e door pocket for the open door.
REMOTE CONTROL ENTRY FUNCTIONS
Door Lock Function
 Operating a remote controller button on the Intelligent Ke y sends the Intelligent Key-ID to the Intelligent Key
unit. Intelligent Key unit conducts a verification of the received key-ID, and if the verification is accepted, a
door lock or door unlock request signal is sent to BCM via CAN communication to lock/unlock the door.
 When door lock/unlock is performed using Intelligent Ke y remote controller button operation, operation con-
firmation is conducted by making hazard lamps flash and Intelligent Key warning buzzer sound.

ENGINE STARTUP FUNCTION
Operation Description
 When ignition knob is pressed, Intelligent Key unit sends request signal from inside key antenna, key-ID ver- ification is conducted with Intelligent Key using two-wa y communication, and if verification is successful, an
ignition rotation prohibition latch release signal is sent to steering lock unit. Steering lock unit releases igni-
tion knob rotation prohibition latch. (Ignition knob can now be turned.)
 When it becomes possible to rotate the ignition knob, “KEY” warning lamp in combination meter lights up green to notify driver that ignition knob can be turned.
NOTE:
When it becomes impossible to rotate the ignition knob, “KEY” warning lamp in combination meter lights up
red.
 When key-ID verification is successful and ignition knob switch is in the ON state, Intelligent Key unit uses CAN communication to send engine start permission signal to BCM.
 When BCM receives engine start permission signal, it uses CAN communication to sent starter request sig-
nal to IPDM E/R so that the engine will start when ignition knob is rotated to START position.
Operation Range
Engine can be started when Intelligent Key is in the v ehicle. However, sometimes engine might not start when
Intelligent Key is on instrument panel, rear parcel shelf, or in glove box.
NOTE:
