DYNAMIC RADAR CRUISE CONTROL SYSTEM ROAD TEST


  1. PROBLEM SYMPTOM CONFIRMATION

    Tech Tips

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


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

    • Operation of 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 (31 mph) and 170 km/h (105 mph).

        *1 Cruise Main Indicator Light
        *2 Multi-information Display
        *3 "SET" Indicator

        Push the cruise control main switch to - SET.

      5. Check that "SET" is indicated on the multi-information display.

      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 (31 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. 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)]

      *1 ON/OFF
      *2 - SET

      Inspect the - (COAST) function.


      1. Turn the main switch on.

      2. Drive at a speed between 50 km/h (31 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. 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)]

      *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 (31 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 selecting 3rd, 2nd, or 1st range with the shift lever in S

        • Turning the main switch off

        • Pulling the cruise control main switch to CANCEL

    5. A01NE58E01

      *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 (31 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 multi-information display.

        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.
