80 |
Engine Speed too high or too low |
The vehicle decelerated because the leading vehicle decelerated, and the engine speed dropped below the mid-speed ranges. |
The driver did not operate the clutch pedal within 10 seconds after the shift-down request was displayed. |
The engine speed returned to the specified speed or higher. |
Prevention of engine stall while the vehicle is decelerating because the leading vehicle is decelerating. |
84 |
Target vehicle comes closer than the radar detecting limits |
|
The leading vehicle slowed down rapidly. |
|
Another vehicle suddenly cut in front of the own vehicle. | |
The distance between the leading vehicle and your vehicle is less than the minimum allowable vehicle-to-vehicle distance.
|
Models with the low speed follow (LSF) feature: 1.5 m (4.9 ft) |
|
Models without the low speed follow (LSF) feature: 5 m (16 ft) | |
The system returns to normal when the distance between the leading vehicle and your vehicle reaches or exceeds the minimum allowable vehicle-to-vehicle distance + 0.5 m (1.6 ft). |
The control is prohibited at a close distance to the leading vehicle where the ACC system is unavailable. If the leading vehicle is too close to your vehicle, the millimeter wave radar may fail to detect the leading vehicle. |

Front wheel spin |
|
Driving on a low ? road |
|
TCS control is executed. | |
A change in the wheel speed equivalent to 0.75 G occurs. |
Other than those listed to the left |
Prevention of use of ACC on a road where vehicle behavior is unstable |
99 |
Acceleration/deceleration abnormality |
|
The inclination of the road changed significantly while the vehicle accelerates/decelerates at around the maximum acceleration/deceleration speed of the ACC system. |
|
The powertrain or brake system is abnormal. | |
|
While the ACC was operating, an acceleration of 0.4 G or more* continued for 1.0 second or more. |
|
While the ACC was operating, a deceleration of -0.5 G or less* continued for 1.5 seconds or more. | |
Other than those listed to the left |
Because the maximum acceleration/deceleration speed for the ACC system is exceeded. |
101 |
Rear wheel locked |
The parking brake is not released or the vehicle is driven on a frozen road surface. |
A signal of 5 mph (8 km/h) or more is inputted to the front wheel sensor and a signal of 0 mph (0 km/h) is inputted to the rear wheel sensor. |
The front and rear wheel sensors detect a wheel speed. |
Prevention of unstable vehicle behavior |
109 |
Movement distance too short after initiation |
When the millimeter wave radar detects an object that turns on low speed follow (LSF) control immediately after vehicle ON mode. |
When the distance the vehicle travels after vehicle ON mode, which is calculated based on the vehicle speed, is less than 8 m (26 ft). |
When the distance the vehicle travels is 8 m (26 ft) or more. |
This is because an object other than a vehicle may be recognized as the leading vehicle after vehicle ON mode in a parking lot etc. |
110 |
Shift position 1st |
|
While driving in 1st gear. |
|
Vehicle is driven at an extremely low speed. | |
1st gear shift position is detected. |
Vehicle is driven in 2nd or higher gear (forward gear). |
Inappropriate gear is selected for ACC system. |
