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.

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.

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.

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.)

Always entrust brake fluid changing to an authorized Volvo retailer.
Power steering fluid reservoir
The fluid level should always be between the ADD and FULL marks.
Fluid type : Volvo synthetic power steering fluid (Pincushion CHF 11S) P/N 1161529 \
or equivalent.
Replace : No fluid change required
NOTE: If a problem should occur in the power steering system or if the vehicle\
has no electrical current
and must be towed, it is still possible to steer the vehicle. However, k\
eep in mind that greater effort will
be required to turn the steering wheel.

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.

ace.
Ventilation hose
WARNING!
- Never expose the battery to open flame or electric spark.
- Do not smoke near the battery.
- Battery fluid contains sulfuric acid. Do not allow battery fluid to co\
ntact eyes, skin, fabrics or
painted surfaces. If contact occurs, flush the affected area immediately\
with water. Obtain medical
help immediately if eyes are affected.

Battery Maintenance (contd)
WARNING!
Ventilation hose: The battery generates hydrogen gas, which is flammable and explosive. T\
he
battery is fitted with a ventilation hose which vents hydrogen gas out o\
f the battery compartment
through a ventilation opening in the bottom of this compartment. If the \
battery must be replaced, it is
essential that the ventilation hose is properly connected to the battery\
and that it is routed through the
ventilation opening provided (see illustration).
Be sure the ventilation hose is free of debris. Only use replacement bat\
teries equipped with a
ventilation hose. Consult your Volvo retailer.
NOTE: After the battery has been disconnected or replaced, lock and unlock the\
vehicle with the central
