Year-by-year variations
Variations by year or market are possible, especially in regions with different glass or wiper standards.

How to confirm the right size
To ensure you purchase the correct blades, check the length printed on the blade you remove, refer to the vehicle’s manual, or use a trusted parts retailer. When in doubt, provide your vehicle’s year, model (GLA 250), and trim to the retailer to receive the exact fitment guidance.
