Hyundai Tucson: Smart Cruise Control Malfunction and Limitations / Limitations of Smart Cruise Control

Smart Cruise Control may not operate normally or may operate unexpectedly if:

Driving on curves

On curves, Smart Cruise Control may not detect a vehicle in the same lane, and may accelerate to the set speed. Your vehicle speed may be reduced if a vehicle is detected in an adjacent lane and your vehicle speed may rapidly decrease when a vehicle ahead is detected suddenly.

Select an appropriate set speed for curves and apply the brake pedal or accelerator pedal depending on the road and driving conditions.

Driving on hills

During uphill or downhill driving, Smart Cruise Control may not detect a moving vehicle in your lane, and cause your vehicle to accelerate to the set speed. Also, your vehicle speed rapidly decreases when a vehicle ahead is detected suddenly.

Select an appropriate set speed on inclines and apply the brake pedal or accelerator pedal depending on the road and driving conditions.

Changing lanes

A: Your vehicle, B: Lane changing vehicle

When a vehicle moves into your lane from an adjacent lane, it cannot be detected by the sensor until it is in the sensor's detection range. Smart Cruise Control may not immediately detect the vehicle when your vehicle changes lanes abruptly. Brake as needed to reduce your driving speed.

Detecting vehicle

Some vehicles in your lane or in be detected by the sensor:

- Vehicles offset to one side
- Slow-moving vehicles or suddendecelerating vehicles
- Vehicles with higher ground clearance or vehicles carrying loads that extend past the end of the vehicle
- Vehicles that have the front tilted due to heavy loads
- Oncoming vehicles
- Stopped vehicles
- Vehicles with small rear profile, such as trailers
- Narrow vehicles, such as motorcycles or bicycles
- Vehicles with low (e.g., sports car) or high (e.g. large truck, bus) ground clearance
- Animals and pedestrians
- Making sharp steering inputs when driving
- Driving on narrow or sharply curved roads

Brake as needed to reduce your driving speed.
