When a belt squeal at startup occurs, first check whether the car remains safe to control. Keep hands, hair, and clothing away from moving belts; do not inspect with the engine running. If the symptom is mild and no critical warning appears, note the conditions and arrange a timely inspection.
The owner’s manual gives the vehicle-specific response for warning lights. Look for belt cracks, glazing, contamination, or a visibly misaligned pulley with the engine off. Do not continue a test drive when the car’s behavior becomes unsafe.
Quick educational note
For information, not a diagnosis or repair instruction. Vehicle-specific checks are still required. Consult the manufacturer's guidance and a qualified technician.
