Inspect cracking, contamination, tracking, tensioner behavior, and pulley condition.
Verify vehicle intervalInterval and replacement scope are engine-specific; failure can cause severe damage on some designs.
Verify vehicle intervalClassify an unfamiliar vehicle noise by location, timing, speed, load, and safety evidence before choosing a system-specific inspection path.
intermediateClassify smoke or a burning smell by location, color, timing, and nearby systems before attempting another drive or touching a hot component.
intermediateThe charging system supports electrical loads and restores energy to the battery. Modern output can change intentionally, so one voltage reading does not automatically prove an alternator is good or bad.
System guideA transmission changes the relationship between engine or motor speed and wheel speed. Shift concerns can originate in fluid condition, controls, sensors, engine operation, mounts, driveline parts, or internal wear.
System guideThe vehicle has detected a charging-system or electrical-generation concern. The battery symbol does not by itself prove the battery failed.
Assess promptlyThe engine or cooling system is reporting excessive temperature or a related protection condition. The warning does not identify whether the cause is coolant loss, airflow, circulation, control, or internal leakage.
Stop and assessAI guidance is separate from verified IAR sources.
