After a prolonged period of driving, do not
turn off the engine immediately after stop-
ping.
•
The engine cooling fan commonly continues
to run for several minutes after the engine
has been turned off.
WARNING

engine compartment, behind the radiator) may
start or continue to operate (for up to
6 minutes) after the engine has been
switched off.

Winter driving
Check your vehicle before the approach of cold
weather.
The following advice is worth noting:
•
Make sure that the engine coolant contains
50 percent antifreeze. Any other mixture will
reduce freeze protection. This gives protec-
tion against freezing down to –31 °F
(–35 °C). The use of "recycled" antifreeze is
not approved by Volvo. Different types of
antifreeze must not be mixed.
•
Volvo recommends using only genuine Volvo
antifreeze in your vehicle's radiator.
•
Try to keep the fuel tank well filled – this
helps prevent the formation of condensation
in the tank. In addition, in extremely cold
weather conditions it is worthwhile to add
fuel line de-icer before refueling.
•
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 warm-
ing up. Full synthetic 0W-30 oil is recom-
mended for driving in areas with sustained
low temperatures.
•
The load placed on the battery is greater dur-
ing 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.
•
To prevent the washer fluid reservoir from
freezing, add washer solvents containing
antifreeze. This is important since dirt is often
splashed on the windshield during winter
driving, requiring the frequent use of the
washers and wipers. 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.
•
Use Volvo Teflon Lock Spray in the locks.
•
Avoid using de-icing sprays as they can
cause damage to the locks.
