l The API Service Symbol "donut" is divided into three parts:
l The upper section describes the oil's performance level.
l The center identifies the oil's viscosity.
l The lower section indicates whether the oil has demonstrated energy-cons\
erving properties in a
standard test in comparison to a reference oil.
pg. 149 Maintenance
Changing engine oil and oil filter
See the previous page for oil specifications and
page 176 for oil volumes. Refer to the Warranty and
Service Records Information booklet for information on the oil change in\
tervals.
NOTE:
l Volvo does not recommend the use of oil additives.
l 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 retailer.
Checking and adding oil
The oil level should be checked every time the vehicle is refueled. This\
is especially important during
the period up to the first scheduled maintenance service.
l The car should be parked on a level surface when the oil is checked.
l If the engine is warm, wait for at least 10-15 minutes after the engine has been switched off\
before
checking the oil.
Checking the oil
1. Pull out the dipstick and wipe it with a lintfree rag.

2. Reinsert the dipstick, pull it out, and check the oil level.
3. Add oil if necessary. If the level is close to the MIN mark, add appr\
oximately 1 US quart (1 liter) of
oil.
4. Run the engine until it reaches normal operating temperature.
5. Switch off the engine and wait for at least 10-15 minutes and recheck\
the oil level. If necessary, add
oil until the level is near the mark.

Oil level should be between the MIN and MAX marks on the dipstick
CAUTION
- Not checking the oil level regularly can result in serious engine dama\
ge if the oil level becomes too
low.
- Never fill oil above the MAX mark. This could cause an increase in oil\
consumption.
- Not checking the oil level regularly can result in serious engine dama\
ge if the oil level becomes too
low.
- Always add oil of the same type and viscosity as already used.
WARNING!
Do not allow oil to spill onto or come into contact with hot exhaust pip\
e
surfaces.

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).
When there is less than approximately 1 US qt (1 liter) remaining in t\
he reservoir, the washer fluid spray
will be directed to the windshield only.
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.

Oil and fluids (contd)
Brake fluid reservoir
The brake fluid should always be above the MIN mark on the side of the r\
eservoir. Check, without
removing the cap, that there is sufficient fluid in the reservoir.
Fluid type : DOT 4+ boiling point >536°F (280°C), P/N 9437433
Replace : Every second year or 30,000 miles (48,000 km). The fluid should be rep\
laced once a year or
every 15,000 miles (24,000 km) when driving under extremely hard condi\
tions (mountain driving, etc.)

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 151)
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 103), 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 four different places:
1. Relays/fuse box in the engine compartment
2. Fuse box in the passenger compartment, behind the plastic cover
3. Fuse box in the passenger compartment, on the edge of the dashboard
4. 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 (and several extra fu\
ses) in the passenger compartment
fuse box on the driver's end of the dashboard. From the side, examine th\
e 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.
