NOTE
Volvo uses different systems to indicate a
low oil level or pressure. Some models have
an oil pressure sensor, in which case a
warning symbol (see page 56) is used to
indicate low oil pressure. Other models have
an oil level sensor, in which case the driver
is alerted by the warning symbol in the cen-
ter of the instrument panel and a text in the
information display. Some models use both
systems. Contact a trained and qualified
Volvo service technician for more informa-
tion.
Changing engine oil and oil filter
See page 208 for oil specifications and page
273 for oil volumes. Refer to the Warranty and
Service Records Information booklet for infor-
mation on the oil change intervals.
NOTE
Volvo does not recommend the use of oil
additives.
Synthetic oil is not used when the oil is
changed at the normal maintenance inter-
vals except at owner request and at addi-
tional charge. Please consult a trained and
qualified Volvo service technician.
Checking and adding oil
G030880
Location of dipstick (1) and oil filler cap (2)
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.
•The vehicle should be parked on a level
surface when the oil is checked.
•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
•Pull out the dipstick and wipe it with a lint-
free rag.
•Reinsert the dipstick, pull it out, and check
the oil level.
•Add oil if necessary. If the level is close to
the MIN mark, add approximately
1 US quart (1 liter) of oil.
•Run the engine until it reaches normal
operating temperature.
•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 damage if the oil level
becomes too low.
•Never fill oil above the MAX mark. This
could cause an increase in oil consump-
tion.
•Not checking the oil level regularly can
result in serious engine damage 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 pipe surfaces.

Fluids09

211 Washer fluid reservoir
G027097
Washer fluid reservoir
The washer fluid reservoir is located in the
engine compartment and holds approx.
6.8 US qts (6.5 liters).
When there is less than approximately 1 US qt
(1 liter) remaining in the reservoir, the washer
fluid spray will be directed to the windshield
only.
During cold weather, the reservoir should be
filled with windshield washer solvent contain-
ing antifreeze.
Changing coolant
G027087
Coolant reservoir
Normally, the coolant does not need to be
changed. If the system must be drained, con-
sult a trained and qualified Volvo service tech-
nician.
CAUTION
•If necessary, top up the cooling system
with Volvo Genuine Coolant/Antifreeze
only (a 50/50 mix of water and anti-
freeze).
•Different types of antifreeze/coolant
may not be mixed.
•If the cooling system is drained, it
should be flushed with clean water or
premixed anti-freeze before it is refilled
with the correct mixture of water/anti-
freeze.
•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 temperatures in the
engine which could result in damage.
Check coolant regularly!
•Do not top up with water only. This
reduces the rust-protective and anti-
freeze qualities of the coolant and has a
lower boiling point. It can also cause
damage to the cooling system if it
should freeze.
•Do not use chlorinated tap water in the
vehicles cooling system.

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, unscrew the
expansion tank cap slowly so that the
overpressure dissipates.
Brake fluid reservoir
G000000
The brake fluid should always be above the
MIN mark on the side of the reservoir. Check,
without removing the cap, that there is suffi-
cient 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 replaced once
a year or every 15,000 miles (24,000 km) when
driving under extremely hard conditions
(mountain driving, etc.).
Always entrust brake fluid changing to a
trained and qualified Volvo service technician.
WARNING
•If the fluid level is below the MIN mark
in the reservoir or if a brake-related
message is shown in the information
display: DO NOT DRIVE. Have the car
towed to a trained and qualified Volvo
service technician and have the brake
system inspected.
•Dot 4+ should never be mixed with any
other type of brake fluid.
Power steering fluid reservoir
FULL
ADD
G026991
The fluid level should always be between the
ADD and FULL marks.
Fluid type: Volvo synthetic power steering fluid
(Pentosin CHF 11S) P/N 1161529 or equiva-
lent.
Replace: No fluid change required.
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, keep 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 compartment.
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 the fol-
lowing in mind:
•Use a screw driver to open the caps or
cover and a flashlight to inspect the level.
•If necessary, add distilled water. The level
should never be above the indicator.
•The fluid level should be checked if the
battery has been recharged.
•After inspection, be sure the cap over each
battery cell or the cover is securely in
place.
•Check that the battery cables are correctly
connected and properly tightened.
•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.
•The battery should be disconnected from
the vehicle when a battery charger is used
directly on the battery.
•To help keep the battery in good condition,
the vehicle should be driven for at least 15minutes a week or connected to a charger
with an automatic charging function.
•If the battery is fully discharged a number
of times, this may shorten its service life.
Keeping the battery fully charged helps
prolong its service life.
•The service life of a battery is affected by
factors such as driving conditions and cli-
mate. Extreme cold may also further
decrease the battery’s starting capacity.
•Because the battery’s starting capacity
decreases with time, it may be necessary
to recharge it if the vehicle is not driven for
an extended period of time or if the vehicle
is usually only driven short distances.
