    Cruise Main Indicator Light

    (Vehicle-to-vehicle distance control mode)

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

    Vehicle Condition Auto Cancel Condition Fail-safe Deactivation Condition

    • Cruise main indicator light goes off

    • Master warning light comes on

    • "CHECK CRUISE CONTROL 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 off

  2. Vehicle-to-vehicle distance control mode:

    Cruise Main Indicator Light

    (Vehicle-to-vehicle distance control mode)

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

    Vehicle Condition Auto Cancel Condition Fail-safe Deactivation Condition

    • Cruise main indicator light goes off

    • Master warning light comes on

    • "CHECK CRUISE CONTROL SYSTEM" is displayed

    • "Pong" warning sound is heard

    • Problem with millimeter wave radar sensor

    *1 Multi-information Display
    *2 Master Warning Light
    *3

    Cruise Main Indicator Light

    (Vehicle-to-vehicle distance control mode)

    If the following conditions are detected while the dynamic radar cruise control system is in operation, the system maintains the stored vehicle speed in the ECM 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 Recover from condition on left (RESUME operation is possible after recovery)

    • Cruise main indicator light goes off

    • 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 sensitivity is reduced 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 in operation, the system clears the stored vehicle speed 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

    • 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


    • Problem with throttle position sensor and motor

    		 Push the cruise control main switch to + RES

    • Cruise main indicator light goes off

    • Master warning light comes on

    • "CHECK CRUISE SYSTEM" is displayed

    • "Pong" warning sound is heard

    • Problem with input circuit of stop light switch circuit


    • Problem with cancel circuit

    		 Engine switch off
