pg. 4:17 Trailer towing
When preparing for trailer towing, observe the following:
●
Use a trailer which meets Federal Safety Standards for rear end collisions (FMVSS 301-75). For
trailer weights exceeding 2000 lbs. (908 kg), use only a trailer hitch offered as a Genuine Volvo
accessory.
NOTE: Models with automatic transmission are equipped with a transmission oil cooler as standard
equipment. This cooler helps prevent overheating of the transmission during times of increased load, as
when towing a trailer.
●
Maximum trailer weight recommended by Volvo is:
Trailers without brakes : 1540 lbs (700kg)
Trailers with brakes: 2" (50 mm) ball - 3300 lbs (1500 kg), 1 7/8" (47 mm) ball - 2000 lbs (900 kg).
Observe the legal requirements of the state/province in which the vehicles are registered.
WARNING! Bumper-attached trailer hitches must not be used on Volvos, nor should safety chains be
attached to the bumper. Trailer hitches attaching to the vehicle rear axle must not be used.
WARNING! Never connect a trailer's hydraulic brake system directly to the vehicle brake system, nor
a trailer's lighting system directly to the vehicle lighting system. Consult your nearest authorized
Volvo dealer for correct installation.
All Volvo models are equipped with energy-absorbing shock-mounted bumpers. Trailer hitch
installation should not interfere with the proper operation of this bumper system.

compensates for load variations. The system operates when the vehicle is in motion. The rear of the
vehicle will however droop if for instance you are carrying a lot of luggage in the trunk or if the vehicle
