HINT: 

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. Inspect the SET function.

   1. Turn the main switch ON.
   2. Drive at the required speed (43 km/h (27 mph) or higher).
   3. Push the cruise control main switch to SET / COAST.
   4. After releasing the switch, check that the vehicle cruises at the set speed.
2. Inspect the ACCELERATION function.

   1. Turn the main switch ON.
   2. Drive at the required speed (43 km/h (27 mph) or higher).
   3. Push the cruise control main switch to SET / COAST.
   4. Check that vehicle speed increases while the cruise control main switch is pushed to RES / ACC, and that the vehicle cruises at the newly set speed when the switch is released.
   5. Momentarily push the cruise control main switch RES / ACC and then immediately release it. Check that vehicle speed increases* (tap-up control).

      HINT: 

      *: Constant speed control mode: increases by 1.6 km/h (1.0 mph); vehicle-to-vehicle distance control mode: increases by 5 km/h (3 mph)

3. Inspect the COAST function.

   1. Turn the main switch ON.
   2. Drive at the required speed (43 km/h (27 mph) or higher).
   3. Push the cruise control main switch to SET / COAST.
   4. Check that vehicle speed decreases while the cruise control main switch is pushed to SET / COAST, and the vehicle cruises at the newly set speed when the switch is released.
   5. Momentarily push the cruise control main switch to SET / COAST, and then immediately release it. Check that vehicle speed decreases* (tap-down control).

      HINT: 

      *: Constant speed control mode: decreases by 1.6 km/h (1.0 mph); vehicle-to-vehicle distance control mode: decreases by 5 km/h (3 mph).

4. Inspect the CANCEL function.

   1. Turn the main switch ON.
   2. Drive at the required speed (43 km/h (27 mph) or higher).
   3. Push the cruise control main switch to SET / COAST.
   4. When performing one of the following, check that the cruise control system is cancelled and that the normal driving mode is reset.
      • Depressing the brake pedal
      • Moving the shift lever to any position except D or S (6th, 5th, and 4th gear) (for 2GR-FSE)
      • Moving the shift lever to any position except D or S (8th, 7th, 6th, 5th, and 4th gear) (for 1UR-FSE)
      • Turning the main switch OFF
      • Pulling the cruise control main switch to CANCEL
5. Inspect the RES (RESUME) function.

   1. Turn the main switch ON.
   2. Drive at the required speed (43 km/h (27 mph) or higher).
   3. Push the cruise control main switch to SET / COAST.
   4. Cancel the cruise control system according to any of the above operations (other than turning the main switch OFF).
   5. After pushing the cruise control main switch to RES / ACC at a driving speed of more than 40 km/h (25 mph), check that the vehicle drives at the set speed.

      HINT: 

      RESUME function in vehicle-to-vehicle distance control mode only: The stored vehicle speed is retained even if vehicle speed goes below 40 km/h (25 mph) once. The previously stored vehicle speed can be resumed by pushing the cruise control main switch to RES / ACC when vehicle speed returned to approximately 40 km/h (25 mph) or more.
