WARNING: This page is about a different car, the 2002 Toyota Camry Solara. However, it is still accessible from the selected car via links, so may be relevant.
Turning On The System : To operate the cruise control, press the "CRUISE ON-OFF " button. See Figure. This turns the system on. The indicator light in the instrument panel shows that you can now set the vehicle at a desired cruising speed. See Figure. Another press will turn the system completely off. Also note that a blinking indicator light is a trouble code display, and counting blinks in between long pauses derives the DTC number. See Figure.
