Driving Your Vehicle

System Limitations

~4min read

The Smart Cruise Control system may have limits in its ability to detect the vehicle ahead due to road and traffic conditions.

On Curves

Hyundai i30. Limitations of the system
  • The Smart Cruise Control system cannot detect a vehicle moving into your lane, and your vehicle may accelerate to the set speed. Also, the vehicle speed will decrease when a vehicle ahead is suddenly detected.
  • Select an appropriate set speed in curves and press the brake or accelerator pedal as necessary.
Hyundai i30. Limitations of the system

Your vehicle's speed may be reduced due to a vehicle in an adjacent lane.

Press the accelerator pedal and select an appropriate set speed. Make sure road conditions allow safe operation of Smart Cruise Control.

On Slopes

Hyundai i30. Limitations of the system
  • When driving uphill or downhill, the Smart Cruise Control system cannot detect a vehicle moving into your lane, which may cause your vehicle to accelerate to the set speed. Also, the vehicle speed will decrease rapidly when a vehicle ahead is suddenly detected.
  • Select an appropriate set speed on slopes and press the brake or accelerator pedal as necessary.

Lane Changes

Hyundai i30. Limitations of the system
  • A vehicle moving into your lane from an adjacent lane cannot be detected by the sensor until it is within the sensor's detection range.
  • The radar may not detect a vehicle immediately when a vehicle suddenly cuts in. Always pay attention to traffic, the road, and driving conditions.
  • If a slower vehicle approaches in your lane, your speed may decrease to maintain the distance to the vehicle ahead.
  • If a faster vehicle moves into your lane, your vehicle will accelerate to the set speed.

Vehicle Recognition

Hyundai i30. Limitations of the system

Some vehicles in your lane may not be detected by the sensor:

- Narrow vehicles, such as motorcycles or bicycles
- Vehicles offset to one side
- Slow-moving vehicles or vehicles that decelerate suddenly
- Stopped vehicles
- Vehicles with a small rear profile, such as unloaded trailers

The vehicle ahead may not be detected correctly by the sensor if any of the following occur:

- When the vehicle is pitched upward due to heavy loads in the cargo area
- While the steering wheel is being operated
- When driving in a one-way lane
- When driving on narrow lanes or on curves

Press the brake or accelerator pedal if necessary.

Hyundai i30. Limitations of the system
  • Your vehicle may accelerate when the vehicle ahead disappears from detection.
  • When you are warned that a vehicle ahead is not detected, drive with caution.
Hyundai i30. Limitations of the system

• When driving in heavy traffic and a stopped vehicle ahead of you merges out of the lane, the system may not immediately detect the new vehicle in front of you. In this case, you must maintain a safe braking distance and, if necessary, press the brake pedal to reduce speed and maintain a safe distance.

Hyundai i30. Limitations of the system

• Always watch for pedestrians when your vehicle is maintaining a distance from the preceding vehicle.

Hyundai i30. Limitations of the system

• Always be careful with vehicles of greater height or vehicles carrying cargo that protrudes from the rear of the vehicle.

WARNING

When using Smart Cruise Control, observe the following precautions:

  • If emergency braking is required, you must apply the brakes. The vehicle cannot be stopped in every emergency situation with the Smart Cruise Control system.
  • Maintain a safe distance according to road conditions and vehicle speed. If the distance to the vehicle ahead is too small while driving at high speed, a serious collision may occur.
  • Always maintain sufficient braking distance and decelerate your vehicle by applying the brakes when necessary.
  • The Smart Cruise Control system cannot detect a stopped vehicle, pedestrians, or oncoming vehicles. Always watch the road ahead carefully to prevent unexpected and sudden situations.
  • Vehicles moving ahead of you that frequently change lanes may cause a delayed system response or may cause the system to react to a vehicle that is actually in an adjacent lane. Always drive carefully to prevent unexpected and sudden situations.
  • Always be aware of the selected speed and the distance to the vehicle ahead. Do not rely solely on the system; always pay attention to driving conditions and control vehicle speed.
  • The Smart Cruise Control system may not recognize complex road situations, so always pay attention to driving conditions and control the speed of your vehicle.

NOTICE

The Smart Cruise Control system may temporarily not operate due to:

  • Electrical interference
  • Suspension modification
  • Differences in tire wear or tire pressure
  • Installation of different types of tires.
