CAUTION Take the following precautions to
maintain optimal performance of the
detecting sensor:
• Never disassemble the detecting sensor or sensor assembly, or cause
any damage to it.
• If the detecting sensors have been replaced or repaired, have the vehicle
inspected by an authorized HYUNDAI
dealer.
• Never install any accessories or stickers on the front windshield, or tint the front
windshield.
• Exercise extreme caution to keep the front view camera dry.

Use only a soft cloth to wash the
vehicle. Do not spray pressurized water
directly on the sensor or sensor cover.
• If the radar or around the radar has been damaged or impacted in any way,
