Quick answer

• Max Towing Capacity: 5,000 lbs
• Max Payload Capacity: 2,425 lbs (Cargo Van), 1,720 lbs (Passenger Van)
• Gross Vehicle Weight Rating (GVWR): 6,834 lbs
• Gross Combined Weight Rating (GCWR): 11,834 lbs
• Curb Weight: 4,110 - 4,683 lbs (varies by configuration)
• Hitch Class: Class III

Tow ratings by engine & trim

The 2021 Mercedes-Benz Metris comes with a single engine option across both Cargo and Passenger Van configurations, but towing and payload capacities can vary slightly based on the specific trim and options.

Note: All ratings are based on a properly equipped vehicle. Always refer to your vehicle's door jamb sticker for precise capacities.

Tow package contents

For the 2021 Mercedes-Benz Metris, an optional trailer hitch is available, which typically includes the necessary wiring harness for trailer lights. While Mercedes-Benz offers a robust platform for towing, certain advanced towing features commonly found on heavy-duty trucks are not standard or available as factory options for the Metris:

• Transmission Cooler: The Metris's transmission is designed to handle the vehicle's rated towing capacity. While an auxiliary transmission cooler isn't a standalone factory option, the vehicle's cooling system is engineered to manage temperatures during towing.
• Integrated Brake Controller: An integrated trailer brake controller is generally not available as a factory option for the Metris. Owners wishing to control electric trailer brakes will need to install an aftermarket brake controller.
• Trailer Sway Control: The Metris may have electronic stability programs that offer some degree of trailer sway mitigation, but a dedicated, advanced trailer sway control system specifically for trailers is not a prominently featured factory option.
• 7-pin Wiring Harness: When equipped with the factory trailer hitch, the Metris typically includes a 7-pin wiring connector providing connections for trailer lights, turn signals, brake lights, and potentially a 12V power supply for the trailer.

5th-wheel & gooseneck

The 2021 Mercedes-Benz Metris is a mid-size commercial van and is not designed for 5th-wheel or gooseneck towing. These types of hitches require a heavy-duty truck chassis and a bed-mounted hitch, which the Metris does not possess. Attempting to install or use a 5th-wheel or gooseneck hitch with a Metris would be unsafe and could lead to severe damage to the vehicle and trailer.

Weight distribution & WDH requirements

For trailers approaching the upper limits of the 2021 Mercedes-Benz Metris's 5,000-pound towing capacity, especially those with a substantial tongue weight (typically 10-15% of the trailer's loaded weight), a weight distribution hitch (WDH) is highly recommended. A WDH helps to distribute the tongue weight more evenly across all axles of the tow vehicle and trailer, restoring lost weight to the front axle of the Metris. This can significantly improve handling, braking, and overall stability, reducing sway and porpoising.

Always consult your owner's manual for specific recommendations regarding WDH use and any tongue weight limits that might trigger the need for one.

Real-world towing tips for this vehicle

• Stay Within Limits: Never exceed the maximum towing capacity, payload capacity, GVWR, or GCWR. Overloading can lead to dangerous handling, reduced braking performance, and premature wear on vehicle components.
• Proper Weight Distribution: Load your trailer correctly, with about 10-15% of the total trailer weight on the tongue. Too much or too little tongue weight can lead to instability.
• Check Tires: Ensure both your Metris and trailer tires are properly inflated to the manufacturer's recommended pressures for towing.
• Brake Controller: If your trailer has electric brakes, an aftermarket trailer brake controller is essential for safe towing.
• Pre-Trip Inspection: Before each trip, check lights, brakes, hitch connection, and safety chains.
• Drive Conservatively: Allow for longer braking distances, accelerate slowly, and avoid sudden maneuvers. Be mindful of crosswinds and road conditions.
• Monitor Temperatures: Keep an eye on your engine temperature, especially on long grades or during hot weather. If available, monitor transmission temperature as well.

Common towing-related issues

While the Metris is a capable tow vehicle, common issues can arise, especially if not prepared properly:

• Reduced Braking Performance: The added weight of a trailer significantly increases stopping distances. Ensure your trailer brakes are functioning correctly if equipped.
• Engine Strain: Towing at or near the maximum capacity, especially in hilly terrain, will put more strain on the 2.0L turbocharged engine. It's designed for this, but regular maintenance is crucial.
• Transmission Overheating: While the transmission is robust, sustained heavy towing in demanding conditions can lead to increased transmission temperatures. Driving in a lower gear can help prevent this.
• Suspension Sag: Heavy tongue weight without a WDH can cause the rear of the Metris to sag, affecting steering and headlight aim. A WDH can mitigate this.
• Trailer Sway: Improper loading, strong crosswinds, or high speeds can induce trailer sway. A WDH can help, but reducing speed is the most effective immediate solution.
