Cold weather precautions
If you wish to check your vehicle before the approach of cold weather, t\
he following 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 vehicle's r\
adiator. Your Volvo
retailer stocks plenty of Volvo engine coolant to help protect your vehi\
cle during 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 cold-weather oil for hard driving or in warm weather. See section "E\
ngine 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 antirust oil on the battery\
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

Normally, the coolant does not need to be changed. If the system must be\
drained, consult your Volvo
retailer.
NOTE: Do not top off with water only. This reduces the rust-protective and ant\
ifreeze qualities of the
coolant and has a lower boiling point. It can also cause damage to the c\
ooling system if it should freeze.
Top off with Volvo Genuine Coolant/Antifreeze only (a 50/50 mix of wate\
r and antifreeze). CAUTION
The cooling system must always be kept filled to the correct level. If i\
t is not kept filled, there can be
high local temperatures in the engine which could result in damage. Diff\
erent types of antifreeze/
coolant may not be mixed.
WARNING!
Never remove the radiator cap while the engine is warm. Wait until the v\
ehicle
cools.

Oil and fluids
Oil quality
Engine oil must meet the minimum ILSAC specification GF-2, including ACE\
A A1, API SJ, SJ/CF and
SJ/Energy Conserving.
Your Volvo has been certified to standards using ILSAC oil specification\
GF-2 5W-30. Volvo
recommends use of oil with a quality rating equal to or higher than ILSA\
C GF-2. Equivalent and better
oils include ACEA A1, API SJ, SJ/CF, and SJ/Energy conserving. Lower qua\
lity oils may not offer the
same fuel economy, engine performance, or engine protection.
Volvo Cars recommends Castrol.
Depending on your driving habits, premium or synthetic oils may provide \
superior fuel economy and
engine protection. Consult your Volvo retailer for recommendations on pr\
emium or synthetic oils.
Oil additives must not be used.
NOTE: Synthetic oil is not used when the oil is changed at the normal maintena\
nce is carried out. This
oil is only used at customer request, at additional charge. Please consu\
lt your Volvo retailer.
Operation in hot climates.
When temperatures exceed 86° F (30° C) in your area, Volvo recom\
mends, for the protection of your
engine, that you use a heavier weight oil, such as SAE 10W-30. See the v\
iscosity chart below.

Changing coolant
Normally, the coolant does not need to be changed. If the system must be\
drained, consult your Volvo
retailer.
NOTE: Do not top off with water only. This reduces the rust-protective and ant\
ifreeze qualities of the
coolant and has a lower boiling point. It can also cause damage to the c\
ooling system if it should freeze.
Top off with Volvo Genuine Coolant/Antifreeze only (a 50/50 mix of wate\

CAUTION
The cooling system must always be kept filled to the correct level. If i\
t is not kept filled, there can be
high local temperatures in the engine which could result in damage. Diff\
erent types of antifreeze/
coolant may not be mixed.
Check coolant regularly!
WARNING!
- Never remove the radiator cap while the engine is warm. Wait until the\
vehicle cools.
- If it is necessary to top up the coolant when the engine is warm, unsc\
rew the expansion tank cap
slowly so that the overpressure dissipates.

The following should be checked regularly:*
1. Washer fluid reservoir should be filled with water and solvent (wint\
ertime: windshield washer anti-
freeze). See
page 131.
2. Power steering - When cold, the level must not be above the COLD mark\
and when hot it must not be
above the HOT mark. Top up if the level drops to the ADD mark with ATF f\
luid. See
page 132.
3. Coolant level should be between the expansion tank marks. Mixture: 50\
% antifreeze and 50% water.
See
page 127.
4. Engine oil should be checked each time the vehicle is refueled. The o\
il level should be between the
dipstick marks. The distance between the marks represents approx. 1.6 US\
qt. (1.5 liter). See
page 130.
5. Brake fluid - check, without removing the cap, that the level is abov\
e the MIN mark. Use brake fluid
DOT 4+. See
page 132.
Fuel octane rating, see
page 84.
Tire pressure, see
page 116, and the label located on the inside of the fuel tank cover.
