HINT:

The dynamic radar cruise control system has 2 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 the cruise control system.

INSPECT SET SWITCH
1. Turn the cruise control main switch on.
2. Drive at the desired speed (40 km/h (25 mph) or higher).
3. Push the cruise control main switch to -SET (COAST/SET).
4. Check that the vehicle cruises at the desired speed.

INSPECT "+" SWITCH
1. Turn the cruise control main switch on.
2. Drive at the desired speed (40 km/h (25 mph) or higher).
3. Push the cruise control main switch to -SET (COAST/SET).
4. Check that vehicle speed increases while the cruise control main switch is pushed to +RES (ACCELERATION/RESUME), and that the vehicle cruises at the set speed when released.

5. Vehicle-to-vehicle distance control mode:
  Momentarily push the cruise control main switch to +RES (ACCELERATION/RESUME), and then immediately release it. Check that the driving and the stored vehicle speed increase by 5 km/h or 5 mph (Tap-up function).
  
  HINT:
  
  Pushing the cruise control main switch to +RES while following a vehicle in front with the vehicle-to-vehicle distance control mode on does not increase the actual vehicle speed, but changes only the stored vehicle speed.
6. Constant speed control mode:
  Momentarily push the control main switch to +RES (ACCELERATION/RESUME), and then immediately release it. Check that the vehicle speed increases by approximately 1.6 km/h (1.0 mph) (Tap-up function).
INSPECT "-" SWITCH

1. Turn the cruise control main switch on.
2. Drive at the desired speed (40 km/h (25 mph) or higher).
3. Push the cruise control main switch to -SET (COAST/SET).
4. Check that vehicle speed decreases while the cruise control main switch is pushed to -SET (COAST/SET), and the vehicle cruises at the set speed when released.
5. Vehicle-to-vehicle distance control mode: Momentarily push the cruise control main switch to -SET (COAST/SET), and then immediately release it. Check that the driving and the stored vehicle speed decrease by 5 km/h or 5 mph (Tap-down function).
6. Constant speed control mode:
  Momentarily push the cruise control main switch to -SET (COAST/SET), and then immediately release it. Check that the vehicle speed decreases by approximately 1.6 km/h (1.0 mph) (Tap-down function).
INSPECT CANCEL SWITCH
1. Turn the cruise control main switch on.
2. Drive at the desired speed (40 km/h (25 mph) or higher).
3. Push the cruise control main switch to -SET (COAST/SET).
4. When performing one of the following, check that the cruise control system is canceled.

  - Depressing the brake pedal.
  - Moving the shift lever from D to N.
  - With the shift lever in S, selecting the S1, S2 or S3 range.
  - Turning the cruise control main switch off (the stored vehicle speed in the ECM is not maintained).
  - Pulling the cruise control main switch to CANCEL.
  - Driving the vehicle while the VSC system is operating.
INSPECT RES (RESUME) SWITCH

1. Turn the cruise control main switch on.
2. Drive at the desired speed (40 km/h (25 mph) or higher).
3. Push the cruise control main switch to -SET (COAST/SET).
4. Cancel the cruise control system by performing any of the operations below.
  - Depressing the brake pedal.
  - Moving the shift lever from D to N.
  - With the shift lever in S, selecting the S1, S2 or S3 range.
  - Pulling the cruise control switch to CANCEL.
  - Driving the vehicle while the VSC system is operating.
5. After the cruise control main switch is pushed to +RES (ACCELERATION/RESUME) at a driving speed of more than 40 km/h (25 mph), check that the vehicle restores the speed before the cancellation.
