Toyota Sienna Service Manual: Cruise Main Indicator Light Circuit

DESCRIPTION

When the cruise control main switch is on, the CRUISE main indicator light and READY indicator light come on. This indicates the control condition (presence or absence of a vehicle in front, vehicle-to-vehicle distance, and set vehicle speed) and fail-safe state through the multiplex communication system. The master warning light and CRUISE main indicator light come on and vehicle-to-vehicle distance information is displayed on the combination meter as the alarm buzzer sounds.

HINT: If the vehicle in front in the same lane significantly decreases vehicle speed or another vehicle cuts in front of your vehicle, adequate deceleration cannot be applied and the vehicle-to-vehicle distance will shorten. At this time, the system sounds the buzzer and the multi-information display blinks to warn the driver.
