Belt check
Check the belt regularly to make sure it is in
good condition and is clean. A worn or dirty belt
can cause poor cooling and low alternator out-
put as well as impair the operation of the power
steering and the air conditioning unit.
NOTE
The drive belt is equipped with a self-ten-
sioning mechanism and requires no adjust-
ment between changes.
WARNING
The engine must not be running when this
check is performed.
Check coolant level
The cooling system must be filled with coolant
and not leak to operate at maximum efficiency.
Check the coolant level regularly. The level
should be between the MAX and MIN marks
on the expansion tank. The check should be
made with particular thoroughness when the
engine is new or when the cooling system has
been drained.
Do not remove the filler cap other than for top-
ping up with coolant. Frequent removal may
prevent coolant circulation between the engineand the expansion tank during engine warm up
and cooling.
Changing coolant
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.
Do not top off with water only. This reduces the
rust-protective and antifreeze qualities of the
coolant and has a lower boiling point. It can
also cause damage to the cooling system if it
should freeze. Top off with Volvo Genuine
Coolant/Antifreeze only (a 50/50 mix of water
and antifreeze.
CAUTION
The cooling system must always be kept
filled to the correct level. If it is not kept filled,
there can be high local temperatures in the
engine which could result in damage. Dif-
ferent types of antifreeze/coolant may not
be mixed.
WARNING
•Never remove the expansion tank cap
while the engine is warm. Wait until the
engine cools.
•If it is necessary to top off the coolant
when the engine is warm, unscrew the
expansion tank cap slowly so that the
overpressure dissipates.

Engine oil 09
220
Oil specifications
Engine oil must meet the minimum
ACEA A5/B5. Lower quality oils may not offer
the same fuel economy, engine performance,
or engine protection.
Oil additives must not be used.
Oil viscosityIncorrect viscosity oil can shorten engine life
under normal use. SAE 5W-30 will provide
good fuel economy and engine protection. See
the viscosity chart.
Viscosity chart
Extreme engine operationSAE 0W-30 oil meeting ACEA A5/B5 require-
ments is recommended for driving in areas with
sustained low temperatures.
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 60) 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 293 for oil volumes. Refer to the
Warranty and Service Records Information
booklet for information on the oil change inter-
vals.
NOTE
Volvo does not recommend the use of oil
additives.
Checking and adding oil
G030880
Location of dipstick (1) and oil filler cap (2)
The oil level should be checked at regular inter-
vals, particularly 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.

09 Maintenance and servicing
Fluids09

WARNING
•Never remove the coolant reservoir cap
while the engine is warm. Wait until the
engine cools.
•If it is necessary to top up the coolant
when the engine is warm, unscrew the
coolant reservoir 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
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.

Overview of information and warning symbols

297 Introduction
The symbols in the vehicle's various displays
are divided into three main categories:
•Warning symbols
•Indicator symbols
•Information symbols
The following tables list the most common
symbols, their meaning and the pages in this
manual that provide more detailed information.
Warning/information symbol
This symbol () lights up and glows red if
the condition is related to safety and/or driva-
bility or yellow to alert the driver to e.g., fill the
washer fluid reservoir, etc. In either case, a
message will be displayed in the instrument
panel display.
