  1. PROBLEM SYMPTOM CONFIRMATION

    Tip:

    • The dynamic radar cruise control system has 2 cruise control modes: constant speed control mode and vehicle-to-vehicle distance control mode.

    • Vehicle-to-vehicle distance control mode is selected by default when the dynamic radar cruise control system is turned on using the cruise control main switch.

      *2 Cruise Control Main Switch
      *3 -SET Switch

      Inspect the SET function.


      1. Turn the dynamic radar cruise control system on using the cruise control main switch.

      2. Check that the cruise control indicator illuminates in the combination meter assembly.

      3. Drive at a speed between approximately 50 km/h (31 mph) or higher.

        *2 Cruise Control SET Indicator

        Push the -SET switch.

      5. Check that the cruise control indicator remains illuminated, the cruise control SET indicator illuminates in the combination meter assembly and the set speed is displayed on the multi-information display.

      6. After releasing the switch, check that the vehicle maintains the set speed.

    2. Inspect the + (ACCEL) function.

        Check that vehicle speed increases while the +RES switch is pushed, and that the vehicle maintains the newly set speed when the switch is released.

      5. Push the +RES switch and then release it immediately. Check that the vehicle speed increases* (tap-up control).

        Tip:

        *: Constant speed control mode: increases by approximately 1 km/h or 1 mph; vehicle-to-vehicle distance control mode: increases by approximately 1 km/h or 1 mph.

    3. Inspect the - (COAST) function.

        Check that vehicle speed decreases while the -SET switch is pushed, and that the vehicle maintains the newly set speed when the switch is released.

      5. Push the cruise control main switch to -SET, and then release it immediately. Check that the vehicle speed decreases* (tap-down control).

        Tip:

        *: Constant speed control mode: increases by approximately 1 km/h or 1 mph; vehicle-to-vehicle distance control mode: increases by approximately 1 km/h or 1 mph.

      *1 Steering Pad Switch Assembly
      *2 Cruise Control Main Switch
      *3 -SET Switch

      Inspect the CANCEL function.


      1. Turn the dynamic radar cruise control system on using the cruise control main switch.

      2. Drive at a speed between approximately 50 km/h (31 mph) or higher.

      3. Push the -SET switch.

      4. B004VSCC16
        *1 Steering Pad Switch Assembly
        *2 CANCEL Switch

        When any of the following are performed, check that control of vehicle speed by the dynamic radar cruise control system is canceled and that the normal driving mode (no control of vehicle speed by the dynamic radar cruise control system) resumes.


        • Depressing the brake pedal.

        • Moving the shift lever from D or S to any other position.

        • Selecting the S3, S2 or S1 range with the shift lever in S.

        • Pushing the CANCEL switch.

        • Turning the dynamic radar cruise control system off using the cruise control main switch (The stored vehicle speed in the hybrid vehicle control ECU assembly is not maintained.).

        • Applying the electrical parking brake (only during vehicle-to-vehicle distance control mode).

    5. Inspect the RES (RESUME) function.


      1. B004VSCC14
        *1 Steering Pad Switch Assembly
        *2 Cruise Control Main Switch
        *3 -SET Switch

        Turn the dynamic radar cruise control system on using the cruise control main switch.

      2. Drive at a speed between approximately 50 km/h (31 mph) or higher.

      3. Push the -SET switch.

      4. Cancel control of vehicle speed by the dynamic radar cruise control system by performing any of the CANCEL functions (other than turning the dynamic radar cruise control system off using the cruise control main switch.

      5. B004VSCC17
        *1 Steering Pad Switch Assembly
        *2 +RES Switch

        Push the +RES switch while driving the vehicle at a speed of more than approximately 40 km/h (25 mph), and check that the vehicle resumes the speed set prior to cancellation and that the cruise control SET indicator illuminates.

        Tip:

        The stored vehicle speed is retained even if vehicle speed drops below approximately 40 km/h (25 mph). The previously stored vehicle speed can be resumed by pushing the +RES switch when the vehicle speed has returned to approximately 40 km/h (25 mph) or more.

  2. CHECK FULL-SPEED RANGE FOLLOWING FUNCTION


    1. Check cruise control setting


      1. B004VSCC18
        *1 Steering Pad Switch Assembly
        *2 Cruise Control Main Switch

        Turn the dynamic radar cruise control system on using the cruise control main switch.

      2. Drive at a speed between approximately 0 km/h (0 mph) and 180 km/h (110 mph).

      3. Check that there is a preceding vehicle that can be tracked.

        Tip:

        Tracking control may not track the preceding vehicle in the following conditions:


        • The rear of the preceding vehicle is small, such as an empty trailer or motorcycle.

      4. B004VSCC15
        *1 Steering Pad Switch Assembly
        *2 -SET Switch

        Push the -SET switch.

      5. Check that tracking of the preceding vehicle begins with the set vehicle speed as the upper limit when the SET switch is pressed.

      6. Check that the set vehicle speed is displayed on the multi-information display in the combination meter assembly.

    2. Check deceleration function


      1. When the preceding vehicle decelerates, check that the vehicle automatically decelerates while maintaining the set vehicle-to-vehicle distance.

      2. When the vehicle stops, check that "WAITING" is displayed on the multi-information display in the combination meter assembly.

        Tip:

        When "WAITING" is displayed on the multi-information display in the combination meter assembly, even if the brake pedal is depressed, dynamic radar cruise control is not canceled.

    3. Check acceleration function


      1. When the preceding vehicle starts off, check that "Push Cruise Control Switch or Press Accelerator to Resume" is displayed on the multi-information display in the combination meter assembly.

      2. B004VSCC17
        *1 Steering Pad Switch Assembly
        *2 +RES Switch

        When the +RES switch is pushed or the accelerator pedal is depressed, check that tracking control resumes and begins tracking the preceding vehicle.

    4. Check tracking control cancel function


      1. When the vehicle speed is approximately 40 km/h (25 mph) or less and the preceding vehicle is no longer in front of the vehicle, check that "CRUISE NOT AVAILABLE" is displayed on the multi-information display in the combination meter assembly and tracking control cancels.

        Tip:

        Tracking control also automatically cancels when the preceding vehicle moves out of the detection range due to a curve, etc., when the vehicle speed is 40 km/h (25 mph) or less.
