    Cruise Main Indicator Light

    (Constant speed control mode)
    *4

    Cruise Main Indicator Light

    (Vehicle-to-vehicle distance control mode)

    If the following conditions are detected while the dynamic radar cruise control system is operating, the system clears the stored vehicle speed in the driving support control ECU and cancels the dynamic radar cruise control operation.

    Tech Tips

    During constant speed control mode, the cruise main indicator light (constant speed control mode) flashes. During vehicle-to-vehicle distance control, the cruise main indicator light (vehicle-to-vehicle distance control mode) flashes.

    Vehicle Condition Auto Cancel Condition Fail-safe Deactivation Condition

    • Cruise main indicator light blinks

    • Master warning light comes on

    • "CHECK CRUISE SYSTEM" is displayed

    • "Pong" warning sound is heard

    • Open or short in stop light switch circuit

    • Problem with vehicle speed signal

    		 Turn cruise control main switch on again

    Cruise Main Indicator Light

    (Vehicle-to-vehicle distance control mode)

    If the following conditions are detected while the dynamic radar cruise control system is operating, the system maintains the stored vehicle speed in the driving support control ECU and cancels the dynamic radar cruise control operation.

    Vehicle Condition Auto Cancel Condition Fail-safe Deactivation Condition

    • Master warning light comes on

    • Cruise main indicator light blinks

    • "CLEAN RADAR SENSOR" is displayed

    • "Pong" warning sound is heard

    		 There is dirt on millimeter wave radar sensor assembly Recover from condition on left (RESUME operation is possible after recovery)

    • Cruise main indicator light blinks

    • Master warning light comes on

    • "CRUISE NOT AVAILABLE" is displayed

    • "Pong" warning sound is heard

    • Wiper switch is in HI position

    • ECT-SNOW switch is on

    • Millimeter wave radar sensor assembly is least sensitive because of bad weather such as rain, fog, snow, and sandstorms

    • Recover from condition on left (RESUME operation is possible after recovery)

    • Turn cruise control main switch on again

  4. Constant speed control mode and vehicle-to-vehicle distance control mode:

    If the following conditions are detected while the dynamic radar cruise control system is operating, the system clears the stored vehicle speed in driving support control ECU and cancels the dynamic radar cruise control operation.

    Vehicle Condition Auto Cancel Condition Fail-safe Deactivation Condition
    Cruise main indicator light goes off

    • Constant Speed Control Mode:

      Vehicle speed is lower than stored vehicle speed by approximately 16 km/h (10 mph) or more while cruise control is operating

    • Constant Speed Control Mode and Vehicle-to-vehicle Distance Control Mode:

      Hybrid control system malfunction

    		 Turn cruise control main switch on again

    Vehicle-to-vehicle Distance Control Mode:

    Vehicle speed is lower than stored vehicle speed by approximately 16 km/h (10 mph) or more while cruise control is operating

    		 Power switch on (IG) again

  5. Constant speed control mode and vehicle-to-vehicle distance control mode:

    If the following conditions are detected while the dynamic radar cruise control system is operating, the system maintain the stored vehicle speed in driving support control ECU and cancels the dynamic radar cruise control operation.

    Vehicle Condition Auto Cancel Condition Fail-safe Deactivation Condition
    Cruise main indicator light goes off Vehicle speed is lower than low speed limit (approximately 40 km/h (25 mph)) while cruise control is operating Push the cruise control main switch to + RES
