DEF refill bottle
DEF refill bottles can be obtained at many gas stations or at an authorized Mercedes-Benz Center. Refill bottles without a threaded cap do not provide overfill protection. DEF may leak if overfilled. Mercedes Benz provides special refill bottles with threaded caps.
These are available at any authorized Mercedes-Benz Center.
