Smart Access System with Push-Button Start (Continued)
Vehicle Starting/Stopping
The smart key has replaced the conventional metal cut key, and the power
button has replaced the ignition switch. The smart key only needs to be in
proximity to the vehicle to allow the system to function.
•
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.

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, check that the READY indicator is
illuminated in the instrument cluster.
•
If the internal smart key battery is dead, use the following method to start
the vehicle.
1. Touch the Lexus emblem side of the smart key to the power button.
2. Within the 10 seconds after the buzzer sounds, push the power button
with the brake pedal depressed (the READY indicator will illuminate).
•
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.
•
To shut off the vehicle before coming to a stop in an emergency, push and
hold down the power button for more than 2 seconds or push the power
button 3 times or more in a row. This procedure may be useful at an
accident scene in which the READY indicator is on, Park cannot be
selected, and the drive wheels remain in motion.
