Oil and fluids
Oil specifications
Engine oil must meet the minimum ILSAC specification GF-3, API SL, or AC\
EA A1/B1. Lower quality
oils may not offer the same fuel economy, engine performance, or engine \
protection.

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 when the normal mainte\
nance is carried out.
This oil is only used at customer request, at additional charge. Please \
consult your Volvo retailer.
Oil Viscosity
Operation in hot climates.
For the protection of your engine when temperatures in your area exceed \
86° F (30° C), Volvo
recommends that you use an oil with suitable viscosity, as shown in the \
chart below.
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
above.
Extreme engine operation
Synthetic oils meeting ACEA A5/B5 requirements are recommended for drivi\
ng in areas of sustained
temperature extremes (hot or cold), when towing a trailer over long di\
stances, and for prolonged driving
in mountainous areas.

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.
pg. 151 Maintenance
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.)
