Setting System

WARNING: This page is about a different car, the 2003 Lexus RX 300 and 2002 Lexus RX 300. However, it is still accessible from the selected car via links, so may be relevant.
  1. Turn the ignition key to the LOCK position and remove it. The engine immobilizer system causes the indicator light to flash.
  2. Close and lock all the doors and hood using an ignition key or wireless remote control. If you unlock them with the wireless remote control, the turn signals flash once (the turn signals can be set not to flash). The flashing indicator light will remain on when all the doors and hood are closed and locked.
  3. After 30 seconds, the indicator starts flashing and the system is set.
