2003 VOLVO XC90
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.

Oil viscosity (stable ambient temperatures)
Operation in temperate climates
Incorrect viscosity oil can shorten engine life. Under normal use when t\
emperatures do not exceed 86° F
(30° C), SAE 5W-30 will provide good fuel economy and engine protec\
tion. See the viscosity chart at
right.
Extreme engine operation
Synthetic oils meeting SAE 10W-30 and complying with oil quality require\
ments are recommended for
driving in areas of sustained temperature extremes (hot or cold), when\
towing a trailer over long
distances, and for prolonged driving in mountainous areas.
Changing oil and oil filter
Oil and oil filter changes should be made at 7,500 mile (12,000 km) in\
tervals.
Volvo does not recommend the use of oil additives.
Synthetic oil is not used when the oil is changed at the normal maintena\
nce intervals except at
ower request and at additional charge. Please consult your Volvo retaile\
r.
l The API Service Symbol "donut" is divided into three parts:
l The top half describes the oil's performance level.
l The center identifies the oil's viscosity.
l The bottom half tells whether the oil has demonstrated energy-conserving\
properties in a standard test
in comparison to a reference oil.

Oil and fluids (contd)
Checking the oil level
The oil level should be checked every time the vehicle is refueled. This\
is especially important
during the period up to the first maintenance. CAUTION
Not checking the oil level regularly can result in serious engine damage\
if the oil level becomes too
low.
Park the vehicle on a level surface and wait for at least 5 minutes afte\
r the engine has been switched
off. Be sure the oil level is maintained between the upper and lower mar\
ks on the dipstick. Low oil
level can cause internal damage to the engine and overfilling can result\
in high oil consumption. The
distance between the dipstick marks represents approx. 1.6 US qt (1.5 l\
iter). The oil should preferably
be checked when cold, before the engine has been started.
NOTE: The engine must be stopped when checking the oil.
WARNING!
Do not allow oil to spill onto or come into contact with hot exhaust pip\
e
surfaces.
Adding oil (topping up)
l Add oil of the same kind as already used.

6-cylinder turbo engine - 7 US qt (6.7 liters)
l The oil filter should be replaced at every oil change.

Washer fluid reservoir
Washer fluid reservoir
The washer fluid reservoir is located in the engine compartment and hold\
s approx. 6.8 US qt (6.5 liters).
During cold weather, the reservoir should be filled with windshield wash\
er solvent containing antifreeze.

Coolant reservoir
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\
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.
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.

Battery Maintenance
The battery in your vehicle is located under the floor of the cargo comp\
artment.
Driving habits and conditions, climate, the number of starts, etc. all a\
ffect the service life and function of
the battery. In order for your battery to perform satisfactorily, keep t\
he following in mind:
l Check the fluid level in each cell in the battery every 24 months or eve\
ry 15,000* miles (24,000 km),
whichever is sooner. The fluid should be at the level shown in the illus\
tration above (A)**.
l Use a screw driver to open the caps and a flashlight to inspect the leve\
l.
l If necessary, add distilled water. The level should never be above the i\
ndicator (A**).
l The fluid level should be checked if the battery has been recharged.
l After inspection, be sure the cap over each battery cell is securely in \
place.
l Check that the battery cables are correctly connected and properly tight\
ened. Route ventilation hose
through opening in floor (see
page 135)
l Never disconnect the battery when the engine is running, for example whe\
n changing the battery.
l The battery should be disconnected from the vehicle when a battery charg\
er is used directly on the
battery.
l However, if the battery is being charged via the connecting points in th\
e engine compartment (see
page 102), the battery must be connected.
* More frequently in warm climates.
** The level indicator inside the battery could be designed in various w\
ays. See illustration.

Replacing fuses
If an electrical component fails to function, it is possible that a fuse\
has blown.
The fuse boxes are located in three different places:
A - Relays/fuse box in the engine compartment
B - Fuse box in the passenger compartment
C - Relays/fuse box in the cargo compartment.
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 (see next page) to see if it is broken. \
If so, put in a new fuse of the same
color and amperage (written on the fuse). Spare fuses are stored in the fuse box in the \
engine
compartment and the passenger compartment. If fuses burn out repeatedly,\
have the electrical system
inspected by an authorized Volvo retailer.
WARNING!
Never use fuses with higher amperage than those stated on the following \
pages. Doing so could
overload the vehicle's electrical system.
