Cold weather precautions
If you wish to check your car before the approach of cold weather, the f\
ollowing advice is worth noting:
l Make sure that the engine coolant contains 50 percent antifreeze. Any ot\
her mixture will reduce
freeze protection. This gives protection against freezing down to -31°\
F (-35°C). See section "Coolant".
The use of "recycled" antifreeze is not approved by Volvo. Different typ\
es of antifreeze must not
be mixed.
l Volvo recommends using only genuine Volvo antifreeze in your car's radia\
tor. Your local Volvo
retailer stocks plenty of Volvo engine coolant to protect your car durin\
g cold weather.
l 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 f\
uel line de-icer before refueling.
l 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 secti\
on "Engine oil" for more
information.
l 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 batter\
y posts.
l Volvo recommends the use of snow tires on all four wheels for winter driving - see section "Wheels
and tires".
l To prevent the washer fluid reservoir from freezing, add washer solvents containing antifreeze (see
page 136 for the location of the washer fluid reservoir). This is important sin\
ce 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 \
l Use Volvo Teflon Lock Spray in the locks.
NOTE: Avoid the use of de-icing sprays as they can cause damage to the locks.
W Winter/Wet driving mode - enhanced vehicle traction
l Mode W will only function if the gear selector is in the (D)rive posit\
ion.
l Press the button at the base of the gear selector to engage/disengage th\
is driving mode.
l An LED in the button will light up to indicate that W is engaged and this will also be displayed in the
instrument panel (see
page 27).
l This mode may be selected for starting/moving off on slippery roads.

Park the car on a level surface and wait for at least 5 minutes after th\
e engine has been switched off. Be
sure the oil level is maintained between the upper and lower marks on th\
e dipstick. Low oil level can
damage the engine. Overfilling can result in high oil consumption and da\
mage the emissions system.
The distance between the dipstick marks represents approx. 1.6 US qt (1\
.5 liter). The oil should
preferably be checked when cold, before the engine has been started.
NOTE: The engine must be stopped when checking the oil. Do not fill to the max\
when the engine is
hot
WARNING!
Do not allow oil to spill onto or come into contact with hot exhaust pip\
e
surfaces.
Adding oil
l Add oil of the same kind as already used.
l Capacity (including oil filter): 6.1 US qts. (5.8 liters)
l Capacity (including oil filter and oil cooler): 7.1 US qts. (6.7 lite\
rs)
l The oil filter should be replaced at every oil change.
R-models
R-models are equipped with an oil level warning system. If the engine oi\
l level becomes too low, the
warning light in the instrument panel will come on and a warning will be\
displayed in the text window.
If the yellow warning light in the instrument panel comes on and the tex\
t OIL LEVEL LOW/FILL
OIL is displayed, stop safely as soon as possible and add 1 qt (1 liter) o\
f oil. Check the oil level with the
dipstick before restarting the engine.

Charge air cooler (Intercooler)
Turbocharged engines employ a turbo-compressor to force air into the eng\
ine inlet manifold and a
charge air cooler to cool the compressed inlet air. The resulting increa\
se in air flow raises pressure in the
intake manifold and increases engine power over that developed by A norm\
ally-aspirated engine. The
charge air cooler (which resembles a radiator) is located between the \
turbo-compressor and inlet
manifold.
