1. Turn the vehicle’s key to the ignition “on” position, tap the Function button 3 times, and finally tap the Lock button. The parking lights
will flash once, the remote will read “VALET ON” and Z’s will show on the LCD above the vehicle’s hood to confirm valet mode.
Repeat this
process to exit valet mode. The parking lights will flash twice, remote read “VALET OFF” and Z’s will disappear confirming valet mode is disabled
