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.

      *b -/SET

      Inspect the SET function.


      1. Turn the cruise control switch (ON-OFF button) on.

      2. Check that the cruise control 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).

        Push the cruise control switch to -/SET.

      5. Check that cruise control SET indication and the cruise control set speed are displayed on the multi-information display.

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

      *b -/SET
      *c +/RES

      Inspect the + (ACCEL) function.


      1. Turn the cruise control switch (ON-OFF button) on.

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

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

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

        Tech Tips

        *: Constant speed control mode: increases by approximately 1.6 km/h (1 mph); vehicle-to-vehicle distance control mode: increases by approximately 1 km/h (1 mph) or 5 km/h (5 mph).

      *a ON/OFF
      *b -/SET

      Inspect the - (COAST) function.


      1. Turn the cruise control switch (ON-OFF button) on.

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

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

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

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

        Tech Tips

        *: Constant speed control mode: decreases by approximately 1.6 km/h (1 mph); vehicle-to-vehicle distance control mode: decreases by approximately 1 km/h (1 mph) or 5 km/h (5 mph).

      *c CANCEL

      Inspect the CANCEL function.


      1. Turn the cruise control switch (ON-OFF button) on.

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

      3. Push the cruise control 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 any other position

        • Pulling the cruise control switch to CANCEL

        • Turning the cruise control switch off (the stored vehicle speed in the driving support ECU is not maintained)

      *a ON/OFF
      *b -/SET
      *c +/RES

      Inspect the RES (RESUME) function.


      1. Turn the cruise control switch (ON-OFF button) on.

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

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

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

      5. After pushing the cruise control switch to +/RES at a driving speed of more than approximately 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 approximately 40 km/h (25 mph) once. The previously stored vehicle speed can be resumed by pushing the cruise control switch to +/RES when the vehicle speed has returns to approximately 40 km/h (25 mph) or more.
