Description and operation

Description

The smart cruise control unit is installed on the front right-hand side of the chassis. A radar sensor is embedded in the front section of the unit. This sensor detects vehicles and objects in front of the vehicle. The radar sensor can detect up to 64 objects ahead of the vehicle. The alarm goes off when the vehicle deviates from the horizontal and vertical alignment reference points during operation. This sensor communicates with the dashboard, warning buzzer, smart cruise control switch, Electronic Stability Program (ESP), ECM, and TCM via CAN communication. The sensor controls vehicle speed through CAN communication between the Electronic Stability Program (ESP) system and the ECM and TCM.

Kia Stinger (CK) 2018-2023 Service Manual: Parking distance warningreverse precautions

The parking distance warningreverse may not sound consistently depending on the speed and shapes of the objects detected. The parking distance warningreverse may malfunction if the vehicle bumper height or sensor installation has been modified or damaged. Any non-factory installed equipment or accessories may also interfere with the sensor performance.

Kia Stinger (CK) 2018-2023 Service Manual: Air bag non-inflation conditions

• In certain low-speed collisions the air bags may not deploy. The air bags are designed not to deploy in such cases because they may not provide benefits beyond the protection of the seat belts in such collisions. • Air bags are not designed to inflate in rear collisions, because occupants are moved backward by the force of the impact.
