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
topping-up with coolant. Frequent removal
may prevent coolant circulations between the
engine tank during engine warm-up and
cooling.

Add coolant until the level is up to
the MAX mark or slightly above.
Start the engine and run until hot.

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
