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.

Inspect the SET function.

Turn the main switch on.
Drive at a speed between approximately 50 km/h (30 mph) and 170 km/h (105 mph).
Push the cruise control main switch to - SET.
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.
Push the cruise control main switch to + RES 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 mph); vehicle-to-vehicle distance control mode: increases by 1 km/h (1 mph).

Inspect the - (COAST) function.

Turn the main switch on.
Drive at a speed between approximately 50 km/h (30 mph) and 170 km/h (105 mph).
Push the cruise control main switch to - SET.
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.
Push the cruise control main switch to - 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 1.6 km/h (1 mph).

Inspect the CANCEL function.

Turn the main switch on.
Drive at a speed between approximately 50 km/h (30 mph) and 170 km/h (105 mph).
Push the cruise control main switch to - SET.
When performing any one of the following, check that the cruise control system is canceled and that the normal driving mode is reset.
- Depressing the brake pedal
- Moving the shift lever from D to any other position
- Turning the main switch off
- Pulling the cruise control main switch to CANCEL

Inspect the RES (RESUME) function.

Fig 6: Inspecting + (ACCEL) Function

Turn the main switch on.
Drive at a speed between approximately 50 km/h (30 mph) and 170 km/h (105 mph).
Push the cruise control main switch to - SET.
Cancel the cruise control system by performing any of the above operations (other than turning the main switch off).
After pushing the cruise control main 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 main switch to + RES when vehicle speed returns to approximately 40 km/h (25 mph) or more.
