DYNAMIC RADAR CRUISE CONTROL SYSTEM ROAD TEST

  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 switch (ON/OFF).

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

      Inspect the SET function.

      1. Turn the dynamic radar cruise control system on using the cruise control switch (ON/OFF).

      2. Check that the cruise control indicator is displayed in the multi-information display.

      3. Drive at a speed between approximately 50 km/h (or 30 mph) and 180 km/h (or 110 mph).

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

      Inspect the + (ACCEL) function.

      1. Turn the dynamic radar cruise control system on using the cruise control switch (ON/OFF).

      2. Drive at a speed between approximately 50 km/h (or 30 mph) and 180 km/h (or 110 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 maintains the newly set speed when the switch is released.

      5. Push the cruise control switch to +/RES and then release it immediately. Check that vehicle speed increases by approximately 1 km/h (or 1 mph) or 5 km/h (or 5 mph)* (tap-up control).

      Inspect the - (COAST) function.

      1. Turn the dynamic radar cruise control system on using the cruise control switch (ON/OFF).

      2. Drive at a speed between approximately 50 km/h (or 30 mph) and 180 km/h (or 110 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 that the vehicle maintains the newly set speed when the switch is released.

      5. Push the cruise control switch to -/SET, and then release it immediately. Check that vehicle speed decreases by approximately 1 km/h (or 1 mph) or 5 km/h (or 5 mph)* (tap-down control).

      CANCEL

      Inspect the CANCEL function.

      1. Turn the dynamic radar cruise control system on using the cruise control switch (ON/OFF).

      2. Drive at a speed between approximately 50 km/h (or 30 mph) and 180 km/h (or 110 mph).

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

      4. When any of the following are performed, check that dynamic radar cruise control system control of vehicle speed 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.

        • for U760E, U760F:

          Moving the shift lever to any position except D or S (6th, 5th or 4th gear).

        • for U660F, K111, K111F, K114F:

          Moving the shift lever to any position except D or M (6th, 5th or 4th gear).

        • w/ Shift Paddle Switch:

          The transmission is changed from 4th gear to 3rd, 2nd or 1st gear with the transmission shift switch assembly while the shift lever is in D or M.

        • for Manual Transaxle:

          • Vehicle-to-vehicle Distance Control Mode:

            • Clutch pedal is depressed for a certain period of time or longer.

            • Moving the shift lever to neutral and waiting for a certain amount of time.

          • Constant Speed Control Mode:

            Depressing the clutch pedal.

        • Pulling the cruise control switch to CANCEL.

        • Turning the dynamic radar cruise control system off using the cruise control switch (ON/OFF). The stored vehicle speed in the ECM is not maintained.

      *b

      -SET

      *c

      +RES

      Inspect the RES (RESUME) function.

      1. Turn the dynamic radar cruise control system on using the cruise control switch (ON/OFF).

      2. Drive at a speed between approximately 50 km/h (or 30 mph) and 180 km/h (or 110 mph).

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

      4. Cancel the dynamic radar cruise control system control of vehicle speed by performing any of the above operations (other than turning the dynamic radar cruise control system off using the ON/OFF switch).

      5. After pushing the cruise control switch to +/RES at a speed of more than approximately 40 km/h (or 25 mph), check that the vehicle resumes the speed set prior to cancellation and that the cruise control SET indicator comes on.

        Tip:

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