DYNAMIC RADAR CRUISE CONTROL SYSTEM > ROAD TEST

for Preparation Click here

HINT:

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

1. Vehicle-to-vehicle distance control mode is always selected when starting up the dynamic radar cruise control system.
   
2. Operation of constant speed control mode is the same as that for a conventional cruise control system.
   

1. 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).
      

   
   
   

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

      *4	Cruise Control SET Indication

   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.
      





2. Inspect the + (ACCEL) function.

   *b	-/SET
   *c	+/RES

   
   

   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).
      

      HINT:

      *: 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).





3. Inspect the - (COAST) function.

   *a	ON/OFF
   *b	-/SET

   
   

   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).
      

      HINT:

      *: 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).





4. Inspect the CANCEL function.

   *a	ON/OFF
   *b	-/SET
   *c	CANCEL

   
   

   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.
      

      1. Depressing the brake pedal
         
      2. Moving the shift lever from D to any other position
         
      3. Pulling the cruise control switch to CANCEL
         
      4. Turning the cruise control switch off (the stored vehicle speed in the driving support ECU is not maintained)
         





5. Inspect the RES (RESUME) function.
   

   Text in Illustration 

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

   
   

   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.
      

      HINT:

      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.
