Check, without removing the cap, that the level is above
the "MIN" mark of the fluid reservoir.
Always entrust brake fluid changing to an authorized
Volvo retailer.
Drive belt pg. 117
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 generator output as well as impair the
operation of the power steering and the air conditioning
unit.
WARNING! The engine must not be running when
this check is performed. NOTE: The belt is equipped with a self-questioning
mechanism and requires no adjustment between changes.
Cooling system pg. 118
Changing coolant
Normally, the coolant does not
need to be changed. If the system
must be drained, use the following
procedure:
Remove the expansion tank cap.
Open the drain cock on the right
side of the engine block and
disconnect the lower radiator
hose.
Fill coolant through the expansion
tank. The heater controls should
be fully open when draining and
WARNING: If the engine is
warm and you are going to top
up coolant, unscrew the cap
slowly in order to allow any
excess pressure to escape.
NOTE: Do not top up with water
only. Water by itself 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.

Oil quality
Meeting API specification SG, SG/CD, SH or
Energy Conserving (EC) II
For best fuel economy and engine protection,
consult with your authorized Volvo retailer for
recommended oils. Oil with a different quality
rating may not provide adequate engine
protection.
Synthetic oils complying with oil quality
requirements are recommended for: driving in
areas of sustained temperature extremes (hot or
cold), when towing a trailer over long distances or
for prolonged driving in mountainous areas.
Extra oil additives must not be used unless
advised by an authorized Volvo retailer.
NOTE:SAE 15W/40 should only be used in
extreme operating conditions such as trailer
towing in sustained ambient temperatures over
104° F (40° C). However, SAE 10W-30 synthetic
oil would be a better alternative in such
conditions.
SAE 15W-40 should not be used under normal
operating conditions.

Vehicle Loading
The tires on your Volvo should perform to
specifications at all normal loads when inflated as
recommended on the tire information label. The
label is located on the rear-facing edge of the
right-front door. This label lists both tire and
vehicle design limits. Do not load your car beyond
the load limits indicated.
WARNING!
Improperly inflated tire will reduce tire life,
adversely affect vehicle handling and can possibly
lead to failure resulting in loss of vehicle control
without prior warning.

Cassettes
l Store cassettes in their cases.
l Do not touch the tape surface
with your fingers.
l Tapes should not be exposed to
direct sunlight or extreme
temperatures.
l Keep tapes away from oil,
grease and other contaminants.
l For optimal tape deck
performance Volvo does not
recommend the use of C-120
tapes.
l Take up slack using a pen or a
pencil before inserting a cassette
in the cassette slot.
Cassette cleaning
We recommend the use of the
Volvo Cleaning Cassette available
as a genuine Volvo accessory.
Regular use improves sound
quality, cleans vital parts and
prevents tape tangle. Compact disc care
l Before using a new disk for the
first time, remove any burrs in the
center/outer edge by running the
stem of a pen or similar object
around the hole/edge of the disc.
l Use high quality discs only.
l Keep the discs clean. Wipe
them with a soft, clean, lint-free
cloth, working from the center
outwards. If necessary, dampen
the cloth with a neutral soap
solution. Dry thoroughly before
using.
l Never use cleaning spray or
antistatic liquid. Use only cleaners
specifically made for CD's.
l Use discs of the correct size
only (3.5" discs should never be
used).
l Do not put tape or labels on the
disc itself.
l Volvo does not recommend the
use of plastic outer rings on the
disc.
l Condensation may occur on
discs/optical components of the
changer in cold winter weather.
The disc can be dried with a clean,
lint-free cloth. Optical
components in the CD changer
may, however, take up to one hour
to dry off.
l Never attempt to play a disc
which is damaged in any way.
l When not in use, the discs
should be stored in their covers.
Avoid storing discs in excessive
heat, direct sunlight or dusty
