Smart Access System and Push Button Start

Smart Access System & Push Button Start
The GS450h smart access system consists of a smart key transceiver that communicates bi-directionally enabling the vehicle to recognize the smart key in close proximity to the vehicle. Once recognized, the smart key will allow the user to lock and unlock the doors without pushing smart key buttons, and start the vehicle without inserting it into an ignition switch.




Smart key features:
- Passive (remote) function to lock/unlock the doors and start the vehicle.
- Wireless transmitter to lock/unlock the doors.
- Hidden metal cut key to lock/unlock the doors from the exterior door lock.

Door (Lock/Unlock)
Three methods are available to lock/unlock the doors.
1. Pushing wireless smart key lock/unlock buttons.
2. Touching the sensor on the backside of any exterior door handle, with the smart key in close proximity to the vehicle, unlocks the doors. Pushing the lock button on any exterior door handle locks the doors.
3. Inserting the hidden metal cut key in the driver door lock and turning clockwise once unlocks the driver door, twice unlocks all doors. To lock all doors turn the key counter-clockwise once. Only the driver door contains an exterior door lock for the metal cut key.

Vehicle Starting/Stopping
The smart key has replaced the conventional metal cut key, and the power button with an integral status indicator light has replaced the ignition switch. The smart key only needs to be in proximity to the vehicle.




- With the brake pedal released, the first push of the power button operates the accessory mode, the second push operates the ignition-on mode, and the third push turns the ignition off again.




Ignition Mode Sequence (Brake pedal released)

- Starting the vehicle takes priority over all other ignition modes and is accomplished by depressing the brake pedal and pushing the power button once. To verify the vehicle has started, the power button status indicator light is off and the READY light is illuminated in the instrument cluster.

- If the internal smart key battery is dead, it cannot communicate with the vehicle. In order for the vehicle to recognize the smart key, the driver must hold the smart key next to the power button while pushing.

- Once the vehicle has started and is on and operational (READY-ON), the vehicle is shut off by bringing the vehicle to a complete stop, placing the gearshift lever in Park, and then depressing the power button once.
