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

    Table 1. Text in Illustration
    *1 Master Warning Light
    *2 Cruise Control Indicator Light (Constant Speed Control Mode)
    *3 Multi-information Display
    *4 Cruise Control 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 control indicator light turns off

    • Master warning light comes on

    • "CHECK CRUISE CONTROL SYSTEM" is displayed

    • "Pong" warning sound is heard

    • There is an open or short in the stop light switch circuit

    • There is a problem with the vehicle speed signal

    		 Turn the cruise control main switch on again

  2. 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 in the ECM and prohibits the dynamic radar cruise control operation.

    Vehicle Condition Auto Cancel Condition Fail-safe Deactivation Condition
    Cruise control indicator light turns off There is a problem with the throttle position sensor and the motor Turn the cruise control main switch on again

    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 control indicator light (vehicle-to-vehicle distance control mode) turns off

    • Master warning light comes on

    • "CHECK CRUISE CONTROL SYSTEM" is displayed

    • "Pong" warning sound is heard

    • There is a problem with the millimeter wave radar sensor

    • The beam axis of the millimeter wave radar sensor deviates

    • There is a problem with the radar cruise control system

    		 Turn the engine switch on (IG)
  5. A0158TEE01

    Vehicle-to-vehicle distance control mode:

    Table 4. Text in Illustration
    *1 Master Warning Light
    *2 Cruise Control Indicator Light (Vehicle-to-vehicle Distance Control Mode)
    *3 Multi-information Display

    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

    • Cruise control indicator light (vehicle-to-vehicle distance control mode) turns off

    • Master warning light comes on

    • "CLEAN RADAR SENSOR" is displayed

    • "Pong" warning sound is heard

    There is dirt on the millimeter wave radar sensor.

    Tip:

    When there is snow or water droplets on the front grill, the fail-safe function may operate.

    		 Recover from the condition on left (RESUME operation is possible after recovery)
  6. A015D3RE01

    Vehicle-to-vehicle distance control mode:

    Table 5. Text in Illustration
    *1 Master Warning Light
    *2 Cruise Control Indicator Light (Vehicle-to-vehicle Distance Control Mode)
    *3 Multi-information Display

    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

    • Cruise control indicator light (vehicle-to-vehicle distance control mode) turns off

    • Master warning light comes on

    • "CRUISE CONTROL NOT AVAILABLE" is displayed

    • "Pong" warning sound is heard

    • The wiper switch is in HI position

    • The ECT 2nd Start switch is on

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

  7. Constant speed control mode:

    If the actual vehicle speed is 16 km/h (10 mph) less than the set vehicle speed 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, as the load on the vehicle may be excessive or the set vehicle speed may be set too high.

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

    If the actual vehicle speed drops below the low speed limit (approximately 50 km/h [30 mph]) while the dynamic radar cruise control system is in operation, the system maintains the stored vehicle speed in the ECM when in vehicle-to-vehicle distance control mode and clears the stored vehicle speed in the ECM when in constant speed control mode and cancels the dynamic radar cruise control operation.

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

    If the VSC system operates or a cancel request is received from the 4WD system 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.
