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 section "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 dri\
ving - see section "Wheels
and tires".
l To prevent the washer fluid reservoir from freezing, add washer solvents\
containing antifreeze (see
page 130 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 (see
illustration).
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.

pg. 105 Long distance trips
Before a long distance trip
It is always worthwhile to have your car checked at a Volvo retailer bef\
ore driving long distances. Your
retailer will also be able to supply you with bulbs, fuses, spark plugs \
and wiper blades for your use in the
event that problems occur.
As a minimum, the following items should be checked before any long trip\
:
l Check that engine runs smoothly and that fuel consumption is normal.
l Check for fuel, oil, and fluid leakage.
l Check condition of accessory drive belts.
l Check transmission oil level*.
l Check state of the battery's charge.
l Examine tires carefully (the spare tire as well), and replace those th\
at are worn. Check tire pressures.
l The brakes, front wheel alignment, and steering gear should be checked b\
y your Volvo retailer only.
l Check all lights, including high beams.
l Reflective warning triangles are legal requirement in some countries.
l Have a word with your Volvo retailer if you intend to drive in countries\
where it may be difficult to
obtain the correct fuel.
l Consider your destination. If you will be driving through an area where \
snow or ice are likely to
occur, consider snow tires.
* To prevent injury from contact with hot surfaces, do not inspect your \
car's transmission fluid yourself.
Have your car's transmission fluid level inspected by a qualified Volvo \
service technician.

Three-way catalytic converter cautions
l Keep your engine properly tuned. Certain engine malfunctions, particular\
ly involving the electrical,
fuel or distributor ignition systems, may cause unusually high three-way\
catalytic converter
temperatures. Do not continue to operate your vehicle if you detect engine misfire, no\
ticeable loss of
power or other unusual operating conditions, such as engine overheating \
or backfiring. A properly
tuned engine will help avoid malfunctions that could damage the three-wa\
y catalytic converters.
l Do not park your car over combustible materials, such as grass or leaves\
, which can come into contact
with the hot exhaust system and cause such materials to ignite under cer\
tain wind and weather
conditions.
l Excessive starter cranking (in excess of one minute), with an intermit\
tently firing or flooded engine,
can cause three-way catalytic converter or exhaust system overheating.
l Remember that tampering or unauthorized modifications to the engine or t\
he vehicle may be illegal
and can cause three-way catalytic converter or exhaust system overheatin\
g. This includes:
- Altering fuel injection setting or components.
- Altering emission system components or location or removing components\
.
- Repeated use of leaded fuel.
NOTE: Unleaded fuel is required for cars with three-way catalytic converters \

pg. 116 Fuses

Replacing fuses
If an electrical component fails to function, it is possible that a fuse\
has blown due to a temporary circuit
overload.
Fuses are located in different places:
A - Relays/fuse box in the engine compartment
B - Fuse box in the passenger compartment
C - Relays/fuse box in the cargo area
A label on the inside of each cover indicates the amperage and the elect\
rical components that are
connected to each fuse.
The easiest way to see if a fuse is blown is to remove it. Pull the fuse\
straight out. If a fuse is difficult to
remove, you will find a special fuse removal tool in the passenger compa\
rtment fuse box. From the side,
examine the curved metal wire to see if it is broken. If so, put in a ne\
w fuse of the same color and
amperage (written on the fuse). Spare fuses are stored in the fuse box in the \
passenger compartment. If
fuses burn out repeatedly, have the electrical system inspected by an au\
thorized Volvo retailer.
WARNING!
Never use fuses with higher amperage that those stated on the following \
pages. Doing so could
overload the car's electrical system.
