Toyota Sienna Service Manual: Road test

1. PROBLEM SYMPTOM CONFIRMATION

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

PROBLEM SYMPTOM CONFIRMATION

  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 - (COAST)/SET.
  4.  After releasing the switch, check that the vehicle cruises at the set speed.

PROBLEM SYMPTOM CONFIRMATION

  1. Inspect the + (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 - (COAST)/SET.
  4.  Check that vehicle speed increases while the cruise control main switch is pushed to + (ACCEL)/RES (RESUME), and that the vehicle cruises at the newly set speed when the switch is released.
  5.  Push the cruise control main switch to + (ACCEL)/RES (RESUME) and then release it immediately. 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 mph (for USA) or 5 km/h (for Canada).

PROBLEM SYMPTOM CONFIRMATION

  1. 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 - (COAST)/SET.
  4.  Check that vehicle speed decreases while the cruise control main switch is pushed to - (COAST)/SET, and that the vehicle cruises at the newly set speed when the switch is released.
  5. Push the cruise control main switch to - (COAST)/SET, and then release it immediately.

    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 mph (for USA) or 5 km/h (for Canada).

PROBLEM SYMPTOM CONFIRMATION

  1. 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 - (COAST)/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.

PROBLEM SYMPTOM CONFIRMATION

  1. 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 - (COAST)/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 + (ACCEL)/RES (RESUME) at a driving speed of more than 40 km/h (25 mph), check that the vehicle resumes the speed set prior to the cancellation.

HINT: 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 + (ACCEL)/RES (RESUME) when vehicle speed returned to approximately 40 km/h (25 mph) or more.
