Important Instructions for Using Adaptive Cruise Control

Chapter 5 · Manual page 256

The adaptive cruise control system is designed as a comfort system. It provides assistance to the driver, but DOES NOT replace any of the driver’s responsibilities. When using the adaptive cruise control system, it is important that the driver maintains concentration at ALL times and is prepared to take action. Otherwise, accidents or personal injuries may occur.

It is the driver’s responsibility to cruise at a safe speed and maintain a safe following distance based on road conditions and applicable speed limits.

The adaptive cruise control system is designed for motorways and roads in good condition. It is not recommended for use on urban roads and mountain roads.

After following the vehicle ahead to a stop with the adaptive cruise control system, the driver must ensure that there are no obstacles or other traffic participants (such as pedestrians) directly in front of the vehicle before starting off to follow the vehicle ahead again.

Whilst using the car following cruise function, it is strongly recommended that the driver does not touch the accelerator pedal. Any activation of the accelerator will not allow the adaptive cruise control system to automatically apply the brakes, and the vehicle is only controlled by the driver’s manipulation of the accelerator pedal.

DO NOT exit the vehicle when the adaptive cruise control system is holding the car stationary. Before leaving the vehicle, always shift into P gear and ensure that the vehicle has been powered off.

If the adaptive cruise control system is holding the car stationary, the driver still needs to pay full attention and be ready to apply the brakes manually. Please note that the vehicle will no longer remain stationary and may move forward or slip on a slope if the function is deactivated, turned off or canceled at any time.

When driving on a bend, the adaptive cruise control system may actively reduce the vehicle speed to ensure driving safety.

Adaptive cruise control system may be unable to provide adequate speed control because of limited braking capability on hills. It can also misjudge the distance from a vehicle ahead. Driving downhill can increase driving speed, causing the vehicle to exceed your set speed (and potentially the road’s speed limit).

Adaptive cruise control system may occasionally cause the vehicle to brake when not required or when you are not expecting it. This can be caused by closely following a vehicle ahead, detecting vehicles or objects in adjacent lanes (especially on bends), etc.

If the vehicle ahead continuously makes hard acceleration or deceleration actions, the ACC system may not be able to maintain the following distance accurately, the driver must pay attention and perform operations such as braking or lane change in time according to the surrounding environment.

If the driver actively applies the accelerator pedal when the adaptive cruise control is active, the speed will be controlled by the accelerator pedal, and the system will not automatically decrease the speed, requiring the driver to maintain a safe distance. With the accelerator pedal released, the adaptive cruise control system will resume to the preset target cruise speed. The adaptive cruise control system is limited or does not work even if it is enabled in the following conditions:

  • Encounter a vehicle or object which is stationary or traverses the lanes (including but not limited to traffic cones, water-filled barriers, construction warning signs, etc.);
  • Approach the vehicle ahead so fast that the system cannot apply sufficient braking;
  • There is oncoming traffic or the vehicle ahead applies emergency braking;
  • The vehicle ahead reverses;
  • A vehicle suddenly cuts into the lane in front;
  • Encounters a vehicle driving at a low speed;
  • Encounters a vehicle with loaded items protruding from the body contour;
  • Encounters a vehicle with a higher chassis (e.g., a truck);
  • Encounters pedestrians, non-motor vehicles or animals;
  • The vehicle is driving on an uneven road or a complex traffic road section;
  • The vehicle makes a sharp turn;
  • The vehicle is passing through a tunnel or driving in the tunnel;
  • The vehicle is driving under the mottled tree shadow;
  • Overload at the cargo area causes the vehicle head tilting upward. Special Driving Environments: If the adaptive cruise control system is used in the following special driving environments, the driver must pay special attention to surroundings, select a suitable speed and be prepared to take full control at all times:
  • When turning at the intersection or driving into or out of the bend following the vehicle ahead, the adaptive cruise control system may be unable to detect the vehicle ahead on the same lane, or may respond to the vehicles in another lane.
  • If the vehicle ahead changes the lane, but not driving into the new lane completely, the adaptive cruise control system may be unable to detect the vehicle.
  • If the vehicle ahead changes lane, but does not exit the original lane completely, the adaptive cruise control system may determine that the vehicle ahead has already left and accelerates.
  • When driving on a steep slope, the adaptive cruise control system can not detect the vehicle in the same lane, so please do not use the adaptive cruise control system.
  • When driving at a small body width overlap ratio with the vehicle ahead, the adaptive cruise control system may be unable to detect the vehicle. Note: It is recommended to turn off the adaptive cruise control system in the following situations:
  • Driving in bad weather conditions;
  • When the ambient light is insufficient, the light is too bright or the forward lighting of the vehicle is poor;
  • Driving on rough or poor road surfaces;
  • Driving through roadworks or construction sites;
  • Driving on low friction roads (the rapid change of the tyre traction may result in the excessive wheel slip).
  • Driving on the entry-exit road or sharp bends.
  • There is no center line separation from the oncoming lane, no lane lines, no lane line at the exit, roundabout, and roadside stationary vehicles.
