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 the conventional type cruise control system.
1. Inspect the SET function.
  1. Push the ON-OFF button on.
  2. Drive at the required speed (45 km/h (28 mph) or higher).
  3. Push the cruise control main switch to SET/COAST.
  4. After releasing the switch, check that the vehicle cruises at the set speed.

  1. Push the ON-OFF button on.
  2. Drive at the required speed (45 km/h (28 mph) or higher).
  3. Push the cruise control main switch to SET/COAST.
  4. Check that vehicle speed increases while the cruise control main switch is pushed to RES/ACC, and that the vehicle cruises at the newly set speed when the switch is released.
  5. Momentarily push the cruise control main switch to RES/ACC and then immediately release it. Check that vehicle speed increases (*1) (Tap-up function).
    *1: Constant speed control mode: increases by 1.6km/h (1.0 mph), Vehicle-to-vehicle distance control mode: increases by 5km/h (5mph)

3. Inspect the COAST function.
  1. Push the ON-OFF button on.
  2. Drive at the required speed (45 km/h (28 mph) or higher).
  3. Push the cruise control main switch to SET/COAST.

  5. Momentarily push the cruise control main switch to SET/COAST, and then immediately release it. Check that vehicle speed decreases (*1) (Tap-down function).
    *1: Constant speed control mode: decreases by 1.6km/h (1.0 mph), Vehicle-to-vehicle distance control mode: decreases by 5km/h (5mph)
4. Inspect the CANCEL function.
  1. Push the ON-OFF button on.
  2. Drive at the required speed (45 km/h (28 mph) or higher).
  3. Push the cruise control main switch to SET/COAST.
  4. When doing one of the following, check that the cruise control system is cancelled and that the normal driving mode is reset.
    - Depressing the brake pedal
    - Moving the shift lever to any position except D (6th, 5th, and 4th gears)
    - Pushing the ON-OFF button off
    - Pulling the cruise control main switch to CANCEL

5. Inspect the RES (RESUME) function.
  1. Push the ON-OFF button on.
  2. Drive at the required speed (40 km/h (25 mph) or higher).
  3. Push the cruise control main switch to SET/COAST.
  4. When doing one of the following, check that the cruise control system is cancelled and that the normal driving mode is reset.
    - 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.
