PROBLEM SYMPTOM CONFIRMATION
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 (45 km/h (28 mph) or higher).
  3. Push the cruise control main switch to -/SET.
  4. After releasing the switch, check that the vehicle cruises at the set speed.
2. Inspect the ACC (ACCEL) function.
  1. Turn the main switch ON.

  2. Drive at the required speed (45 km/h (28 mph) or higher).
  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. Momentarily push the cruise control main switch +/RES 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 (45 km/h (28 mph) or higher).
  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. Momentarily push the cruise control main switch to -/SET, 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 (45 km/h (28 mph) or higher).
  3. Push the cruise control main switch to -/SET.
  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 (5th and 4th gears)
    - 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 (45 km/h (28 mph) or higher).
  3. Push the cruise control main switch to -/SET.
  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 at a driving speed of more than 45 km/h (28 mph), check that the vehicle drives at the set speed.
    HINT:
    
    The stored vehicle speed is retained even if vehicle speed goes below 45 km/h (28 mph) once. The previously stored vehicle speed can be resumed by pushing the cruise control main switch to +/RES when vehicle speed returned to approximately 45 km/h (28 mph) or more.
