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.

The vehicle-to-vehicle distance control mode is always selected when starting up the dynamic laser cruise control system.
Operation of the constant speed control mode is the same as that for the conventional type cruise control system.

  - Depressing the brake pedal
  - Moving the shift lever to any position except D (6th, 5th, and 4th gears)
  - Pulling the cruise control main switch to CANCEL
5. After pushing the cruise control main switch to RES/ACC at a driving speed of more than 40 km/h (25 mph), check that the vehicle restores the speed prior to the cancellation.
HINT:

RESUME function (in the Vehicle-to-vehicle Distance Control Mode only)

The stored vehicle speed is retained even if vehicle speed goes below 40 km/h (25 mph) once. The previously stored vehicle speed can be resumed by pushing the cruise control main switch to RES/ACC when vehicle speed returned to approximately 40 km/h (25 mph) or more.
