Volvo 1991 740 Model
NOTE: Avoid the use of de-icing sprays as they can cause damage to the
locks.
To prevent the washer reservoir from freezing, add washer solvents containing antifreeze. This is
important since the dirt is
often splashed on the windshield during winter driving, thus requiring frequent use of the washers and
wipers. The Volvo
Washer Solvent should be diluted as follows:
Down to 14°F (-10°C): 1 part anti-freeze and 4 parts water
Down to 5°F (-15°C): 1 part anti-freeze and 3 parts water
Down to 0°F (-18°C): 1 part anti-freeze and 2 parts water
Down to -18°F (-28°): 1 part anti-freeze and 1 part water
Automatic differential lock
The differential automatically locks at speed between 3 - 25 mph (5 - 40 km/h) if either of the drive
wheels begins to lose traction. The differential lock improves power distribution to the drive wheels in
slippery conditions, shifting power to the wheel with best traction. It also functions when the
transmission is in reverse.
pg. 4:16 Towing a trailer
When preparing for trailer hauling, observe the following:
Use a trailer hitch 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. Since the automatic transmission is subject to increased load and temperature, certain
vehicles are equipped with an extra oil cooler as standard equipment. Consult your Volvo dealer for
further information.
Maximum trailer weight recommended by Volvo is 3300 lbs (1500 kg). Observe legal requirements
of the state in which the vehicles are registered.
Towing loads above 3,000 lbs (1360 kgs), vehicle should use an automatic transmission cooler.
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.
