2001 Volvo S40 & V40
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.
· The load placed on the battery is greater during the winter since the 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.
· Volvo recommends the use of snow tires on all four wheels for winter driving - see section "Wheels
and tires".
· To prevent the washer fluid reservoir from freezing, add washer solvents containing antifreeze (see
for the location of the
washer fluid reservoir). This is important since dirt is often splashed on the windshield during winter
driving, requiring the frequent use of the washers and wipers. The Volvo Washer Solvent should be
diluted as follows:
Down to 14° F (-10° C): 1 part washer solvent and 4 parts water
Down to 5° F (-15° C): 1 part washer solvent and 3 parts water
Down to 0° F (-18° C): 1 part washer solvent and 2 parts water
Down to -18° F (-28° C): 1 part washer solvent and 1 part water
· When driving in temperatures below 15° F (-10° C), we recommend the use of Volvo's radiator guard
to help the engine reach normal operating temperature as quickly as possible. This guard should not be
used when towing a trailer.
· Use Volvo Teflon Lock Spray in the locks.
· Power steering fluid: Use Pentosin CHF 11 S if your car is used mainly in areas with temperatures
below freezing point.
NOTE: Avoid the use of de-icing sprays as they can cause damage to the locks.
* Synthetic oil is not used when the oil is changed at the normal maintenance service intervals.
