The smart cruise control system may have limits to its ability to detect distance


The smart cruise control system may have limits to its ability to detect distance to the vehicle ahead due to road and traffic conditions.

On curves

  • On curves, the smart cruise control system may not detect a moving vehicle in your lane, and then your vehicle could accelerate to the set speed. Also, the vehicle speed will slow down when the vehicle ahead is recognized suddenly.
  • Select the appropriate set speed on curves and apply the brakes or accelerator pedal if necessary.


  • Your vehicle speed can be reduced due to a vehicle in the adjacent lane. Apply the accelerator pedal and select the appropriate set speed. Check to be sure that the road conditions permit safe operation of the smart cruise control.

On inclines


  • During uphill or downhill driving, the smart cruise control system may not detect a moving vehicle in your lane, and cause your vehicle to accelerate to the set speed. Also, the vehicle speed will slow down when the vehicle ahead is recognized suddenly.
  • Select the appropriate set speed on inclines and apply the brakes or accelerator pedal if necessary.

Lane changing


  • A vehicle which moves into your lane from an adjacent lane cannot be recognized by the sensor until it is in the sensor's detection range.
  • The sensor may not detect immediately when a vehicle cuts in suddenly. Always pay attention to the traffic, road and driving conditions.
  • If a vehicle which moves into your lane is slower than your vehicle, your speed may decrease to maintain the distance to the vehicle ahead.
  • If a vehicle which moves into your lane is faster than your vehicle, you may accelerate if that vehicle is traveling less than your set speed.


  • Your vehicle may accelerate when a vehicle ahead of you disappears.
  • When you are warned that the vehicle ahead of you is not detected, drive with caution.

Vehicle recognition

Some vehicles ahead in your lane cannot be recognized by the sensor as follows:


Some vehicles ahead in your lane cannot be recognized by the sensor as follows:

- Narrow vehicles such as motorcycles or bicycles
- Vehicles offset to one side
- Slow-moving vehicles or suddendecelerating vehicles
- Stopped vehicles
- Vehicles with small rear profile such as trailers with no loads

A vehicle ahead cannot be recognized correctly by the sensor if any of following occurs:

- When the vehicle is pointing upwards due to overloading in the trunk
- When operating the steering wheel
- When driving to one side of the lane
- When driving on narrow lanes or on curves

Apply the brakes or accelerator pedal if necessary.


  • When vehicles are at a standstill and the vehicle in front of you changes to the next lane, be careful when your vehicle starts to move because it may not recognize the stopped vehicle in front of you.


  • Always look out for pedestrians when your vehicle is maintaining a distance with the vehicle ahead.


  • Always be cautious for vehicles with higher height or vehicles carrying loads that sticks out to the back of the vehicle.

WARNING

  • The vehicle cannot be stopped by using the smart cruise control system. If an emergency stop is necessary, you must apply the brakes.
  • Keep a safe distance according to road conditions and vehicle speed. If the vehicle to vehicle distance is too close during a high-speed driving, it may cause a serious collision.
  • The smart cruise control system cannot recognize a stopped vehicle, pedestrians or an oncoming vehicle. Always look ahead cautiously to prevent unexpected and sudden situations from occurring.
  • Vehicles moving in front of you with a frequent lane change may cause a delay in the system's reaction or may cause the system to react to a vehicle actually in an adjacent lane. Always look ahead cautiously to prevent unexpected and sudden situations from occurring.
  • The smart cruise control system is not a substitute for safe driving practices but a convenience function only. It is the responsibility of the driver to always check the speed and the distance to the vehicle ahead.
  • Always be aware of the selected speed and vehicle to vehicle distance.
  • Always maintain sufficient braking distance and decelerate your vehicle by applying the brakes if necessary.
  • As the smart cruise control system may not recognize complex driving situations, always pay attention to driving conditions and control your vehicle speed.
  • For safe operation, carefully read and follow the instructions in this manual before use.

CAUTION

The smart cruise control system may not operate temporarily due to electrical interference.
