DYNAMIC RADAR CRUISE CONTROL SYSTEM ROAD TEST


  1. PROBLEM SYMPTOM CONFIRMATION

    Tech Tips

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


    • The vehicle-to-vehicle distance control mode is always selected when starting up the dynamic radar cruise control system.

    • Operation of the constant speed control mode is the same as that for a conventional cruise control system.

      *1 ON/OFF
      *2 - SET

      Inspect the SET function.


      1. Turn the main switch on.

      2. Check that the cruise main indicator light illuminates on the combination meter assembly.

      3. Drive at a speed between 50 km/h (30 mph) and 170 km/h (105 mph).

        *2 "SET" Indicator
        *3 Multi-information Display

        Push the cruise control main switch to - SET.

      5. Check that "SET" is indicated on the combination meter.

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

      *1 ON/OFF
      *2 - SET
      *3 + RES

      Inspect the + (ACCEL) function.


      1. Turn the main switch on.

      2. Drive at a speed between 50 km/h (30 mph) and 170 km/h (105 mph).

      3. Push the cruise control main switch to - SET.

      4. Check that vehicle speed increases while the cruise control main switch is pushed to + RES, and that the vehicle cruises at the newly set speed when the switch is released.

      5. For Europe

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

        Tech Tips

        *: Constant speed control mode: increases by 1.6 km/h (1.0 mph); vehicle-to-vehicle distance control mode: increases by 5 km/h or 5 mph.

        [Example: 62 → 65 → 70 km/h (or mph)]

      6. For except Europe

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

        Tech Tips

        *: Constant speed control mode: increases by 1.6 km/h (1.0 mph); vehicle-to-vehicle distance control mode: increases by 1.6 km/h or 1 mph.

      *1 ON/OFF
      *2 - SET

      Inspect the - (COAST) function.


      1. Turn the main switch on.

      2. Drive at a speed between 50 km/h (30 mph) and 170 km/h (105 mph).

      3. Push the cruise control main switch to - SET.

      4. Check that vehicle speed decreases while the cruise control main switch is pushed to - SET, and the vehicle cruises at the newly set speed when the switch is released.

      5. For Europe

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

        Tech Tips

        *: Constant speed control mode: decreases by 1.6 km/h (1.0 mph); vehicle-to-vehicle distance control mode: decreases by 5 km/h or 5 mph.

        [Example: 82 → 80 → 75 km/h (or mph)]

      6. For except Europe

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

        Tech Tips

        *: Constant speed control mode: decreases by 1.6 km/h (1.0 mph); vehicle-to-vehicle distance control mode: decreases by 1.6 km/h or 1 mph.

      *1 ON/OFF
      *2 - SET
      *3 CANCEL

      Inspect the CANCEL function.


      1. Turn the main switch on.

      2. Drive at a speed between 50 km/h (30 mph) and 170 km/h (105 mph).

      3. Push the cruise control main switch to - SET.

      4. When performing any one of the following, check that the cruise control system is canceled and that the normal driving mode is reset.


        • Depressing the brake pedal

        • Moving the shift lever from D to N or B position

        • Turning the main switch off

        • Pulling the cruise control main switch to CANCEL

      *1 ON/OFF
      *2 - SET
      *3 + RES

      Inspect the RES (RESUME) function.


      1. Turn the main switch on.

      2. Drive at a speed between 50 km/h (30 mph) and 170 km/h (105 mph).

      3. Push the cruise control main switch to - SET.

      4. Cancel the cruise control system by performing any of the above operations (other than turning the main switch off).

      5. After pushing the cruise control main switch to "+ RES" at a driving speed of more than 40 km/h (25 mph), check that the vehicle resumes the speed set prior to the cancellation and that "SET" is also displayed on the combination meter.

        Tech Tips

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