Sources and documentation scope
Editorial review: 12 September 2026. A reference for finding owner instructions; we do not use it as fault-frequency statistics.
A background reference does not establish how common a fault is. Match maintenance instructions and equipment to the model year, market and VIN; do not transfer a schedule or specification from a different version.
