Towing a trailer Loading a trailer RWhen 201 loading a trailer, please note that neither the permissible gross trailer weight nor the permissible Gross Vehicle Weight Rating (GVWR) may be exceeded. The permissible Gross Vehicle Weight Rating (GVWR) is specified on the type plate located on the B-pillar on the driver's side of your vehicle. You can find the maximum permissible values on the type plates of your vehicle and the trailer. Always observe the lowest respective value when determining the maximum weight with which you can load the vehicle and the trailer. RThe drawbar noseweight acting on the ball coupling has to be added to the rear axle weight in order to prevent the permissible Gross Axle Weight Rating (GAWR) from being exceeded. The permissible Gross Vehicle Weight Rating (GVWR) is specified on the type plate located on the B-pillar on the driver's side of your vehicle. Check the permissible axle weight of the front and rear axle, the Gross Trailer Weight (GTW), and the drawbar noseweight. Trailer power supply The trailer power socket of your vehicle is designed for connecting the 7-pin connector supplied as part of the Mercedes-Benzapproved trailer coupling. i Depending on your trailer, you may need an adapter to connect your trailer to the vehicle. Further information is available from any authorized Mercedes-Benz Center. i Mercedes-Benz recommends loading the trailer so that the drawbar noseweight remains between 8% and 15% of the permissible gross trailer weight. i The weight of additional accessories, passengers, and cargo reduces the permissible trailer load and drawbar noseweight for your vehicle. Checking the vehicle and trailer weight RTo check that the weights of the towing vehicle and the trailer comply with the maximum permissible values, have the vehicle/trailer combination (including the driver, passengers, and cargo with a fully laden trailer) weighed on a calibrated weighbridge. RCheck the permissible axle weight of the front and rear axle, the Gross Trailer Weight (GTW), and the drawbar noseweight. Z Driving and parking
