Volvo recommends .
NOTE
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 owner
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 lint-free 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 MAX mark.

CAUTION
l Not checking the oil level regularly can result in serious engine damage\
if the oil level becomes too
low.
l Oil that is lower than the specified quality can damage the engine.
l Always add oil of the same type and viscosity as already used.
l Never fill oil above the MAX mark. This could cause an increase in oil c\
onsumption.
192 09 Maintenance and servicing
Engine oil
WARNING
Do not allow oil to spill onto or come into contact with hot exhaust pip\
e
surfaces
NOTE
Volvo uses different systems to indicate a low oil level or pressure. So\
me models have an oil pressure
sensor, in which case a warning symbol (see
page 48) is used to indicate low oil pressure. Other models
have an oil level sensor, in which case the driver is alerted by the war\
ning symbol in the center of the
instrument panel and a text in the information display. Some models use \
both systems. Contact an
authorized Volvo retailer for more information.

193 09 Maintenance and servicing
Fluids
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.

Driving habits and conditions, climate, the number of starts, etc., all \
affect 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 15,0001 miles (24,000 km),
whichever is sooner. The fluid should be at the level shown in the illus\
trations above (A). Do not overfill.
l Use a screw driver to open the caps or cover and a flashlight to inspect\
the level.
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 or the cover is\
securely in place.
l Check that the battery cables are correctly connected and properly tight\
ened.
l Never disconnect the battery when the engine is running, or when the key\
is in the ignition. This could
damage the vehicle's electrical system.
l The battery should be disconnected from the vehicle when a battery charg\
er is used directly on the
battery.

Removing the battery
1. Switch off the ignition and remove the key.
2. Wait at least 5 minutes after switching off the ignition before disco\
nnecting the battery so that all

rol modules.
3. Remove the cover over the battery.
4. Disconnect the battery negative (ground) cable.
5. Disconnect the positive cable.
6. Remove the front side of the battery box with a screwdriver.
7. Release the clamp holding the battery.
8. Lift out the battery.
Installing a new battery
1. Put the battery in place in the engine compartment.
2. Install the battery's retaining clamp.
3. Reinstall the front side of the battery box.
4. Connect the positive cable.
5. Connect the ground cable.
6. Reinstall the cover over the battery.
NOTE

Fuses
Replacing fuses
There are relay/fuse boxes located in the engine compartment and the pas\
senger compartment.
If an electrical component fails to function, this may be due to a blown\
fuse. The easiest way to see if a
fuse is blown is to remove it.
To do so:
1. Pull the fuse straight out. If a fuse is difficult to remove, special\
fuse removal tools are located on the
inside of the fuse box covers.
2. From the side, examine the curved metal wire in the fuse to see if it\
is intact.
3. If the wire is broken, insert a new fuse of the same color and amperage (written on the fuse).
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 in the following \
tables. Doing so could overload
the vehicle's electrical system.
