CAUTION
l Engine damage will occur if water is drawn into the air cleaner.
l If the vehicle is driven through water deeper than 9 in (25 cm), water\
may enter the differential and
the transmission. This reduces the oil's lubricating capacity and may sh\
orten the service life of these
components.
l Do not allow the vehicle to stand in water up to the door sills longer t\
han absolutely necessary. This
could result in electrical malfunctions.
l If the engine has been stopped while the car is in water, do not attempt\
to restart the engine. Have the
car towed out of the water.
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 types of an\
tifreeze 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 vehicle durin\
g cold weather.
l Try to keep the fuel tank well filled - this prevents the formation of c\
ondensation 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 (t\
hinner oil) improves cold-weather
starting as well as decreasing fuel consumption while the engine is warm\
ing up. For winter use, 5W-30
oil, particularly the synthetic type
1, is recommended. Be sure to use good quality oil but do not use cold-
weather oil for hard driving or in warm weather. See
page 239 for more information.
l The load placed on the battery is greater during the winter since the wi\
ndshield 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 there\
fore advisable to check the state
of
1Synthetic oil is not used when the oil is changed at the normal maintena\
nce intervals except at owner request and
at additional charge. Please consult your Volvo retailer.

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 dri\
ving - see the chapter "Wheels
and tires."

Periodic maintenance will help keep your vehicle running well. Your Warr\
anty and Service Records
Information booklet provides a comprehensive periodic maintenance schedu\
le up to 150,000 miles
(240,000 km) of vehicle maintenance. The schedule includes components \
that affect vehicle emissions.
This page describes some of the emission-related components.
Vehicle Event Data (Black Box)
Your vehicle's driving and safety systems employ computers that monitor,\
and share with each other,
information about your vehicle's operation. One or more of these compute\
rs may store what they monitor,
either during normal vehicle operation or in a crash or near-crash event\
. Stored information may be read
and used by:
l Volvo Car Corporation
l service and repair facilities
l law enforcement or government agencies
l others who may assert a legal right to know, or who obtain your consent \
to know such information.

Owner maintenance
Periodic maintenance requirements and intervals are described in your ve\
hicle's Warranty and Service
Records Information booklet.
The following points can be carried out between the normally scheduled m\
aintenance services.
Each time the car is refueled:
l Check the engine oil level
l Clean the windshield, windshield wipers, headlights, and taillights
Monthly:
l Check cold tire pressure in all tires. Inspect the tires for wear.
l Check that engine coolant and other fluid levels are between the indicat\
ed "min" and "max" markings.
l Clean interior glass surfaces with a glass cleaner and soft paper towels\
.
l Wipe driver information displays with a soft cloth.
l Visually inspect battery terminals for corrosion. Corrosion may indicate\
a loose terminal connector, or
a battery near the end of its useful service life. Consult your Volvo re\
tailer for additional information.
As needed:
l Wash the car, including the undercarriage, to reduce wear that can be ca\
used by a buildup of dirt, and

Washer fluid
The washer fluid reservoir is located in the engine compartment and hold\
s approximately 6.8 US qts (6.5
liters). During cold weather, the reservoir should be filled with winds\
hield washer solvent containing
antifreeze.
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 cooling s\
ystem if it should freeze. Top off
with Volvo Genuine Coolant/Antifreeze only (a 50/50 mix of water and an\
tifreeze).
CAUTION
The cooling system must always be kept filled to the correct level, and \
the level must be between the
MIN and MAX marks. If it is not kept filled, there can be high local tem\
peratures in the engine which
could result in damage. Different 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 v\
ehicle cools. If it is necessary
to top off the coolant when the engine is warm, unscrew the expansion ta\
nk cap slowly so that the
overpressure dissipates.

The fuse box in the passenger compartment is located under the glove com\
partment.
To access the fuses:
1. Remove the upholstery covering the fuse box by first pressing in the \
center pins in the mounting clips
approximately 0.5 in (1 cm) with a small screwdriver and then pulling \
the pins out.
2. Turn both retaining screws (2) counterclockwise until they release.\
3. Fold down the fuse box (3) half way. Pull it toward the seat until \
it stops. Fold it down completely. The
fuse box can be unhooked completely.
4. Replace the blown fuse.
5. Close the fuse box in reverse order.
6. Pull the center pins fully out of the mounting clips, secure the upho\
lstery with the mounting clips and
press the pins into the mounting clips again. The mounting clips then ex\
pand, holding the upholstery in
position.
