pg. 63 Winter driving
Cold weather precautions
If you wish to check your car before the approach of cold weather, the following advice is worth noting:
●
Make sure that the engine coolant contains at least 50 percent antifreeze: that is, 5.0 qts. (4.25 liters)
Volvo type C blue-green glycol additive. This gives protection against freezing down to -31 ° F(-35 °C).
See section "Coolant".
●
Try to keep the fuel tank well filled-this prevents the formation of condensation in the tank.
In addition in extremely cold weather conditions it is worthwhile to add fuel line deicer before refueling.
●
Use the correct grade of engine oil to avoid difficulties when starting. See section "Engine oil".
●
The load placed on the battery is greater during the winter since the heater, windshield wipers,
lighting etc. are used more often. Moreover, the capacity of the battery decreases as the temperature
drops. In very cold weather, a poorly charged battery can freeze and be damaged. It is therefore
advisable to check the state of charge more frequently and spray an anti-rust oil on the battery posts.
●
The viscosity of the engine oil is important. Oil with low viscosity (thinner oil) improves cold-
weather starting as well as decreasing fuel consumption while the engine is warming up. For winter use,
5W-30 oil. particularly the synthetic type is recommended. Be sure to use good quality oil but do not use
this cold-weather oil for hard driving or in warm weather.
See section "Engine oil" for more information.
●
Use Volvo Teflon lock spray or grease in the locks. They can be purchased from your Volvo dealer.
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 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 °C): 1 part anti-freeze and 1 part water

Before a long distance trip
It is always worthwhile to have your car checked at a Volvo dealer before driving long distances. Your
Dealer will also be able to supply you with bulbs, fuses, spark plugs and wiper blades for your use in the
event that problems occur.
A list of all authorized Volvo dealers in the U.S. and Canada is available.
