Three-way catalytic converter cautions pg. 66
l Keep your engine properly tuned. Certain engine malfunctions,
particularly involving the electrical, fuel or distributor ignition syst\
ems,
may cause unusually high three-way catalytic converter temperatures. Do \
not continue to operate your vehicle if you detect engine misfire,
noticeable loss of power or other unusual operating conditions, such as \
engine overheating or backfiring. Aproperly tuned engine will help avoid\

malfunctions that could damage the three-way catalytic converter.
l Remember that tampering or unauthorized modification to the engine or
the vehicle may be illegal and can cause three-way catalytic converter o\
r
exhaust system overheating. This includes:
-Altering fuel injection settings or components.
-Altering emission system components or location or removing
components -Repeated use of leaded
fuel.
l Do not park your car
over combustible
materials, such as grass
or leaves, which can
come into contact with
the hot exhaust system
and cause such materials
to ignite under certain
wind and weather
conditions.
l Excessive starter
cranking (in excess of
one minute), with an
intermittently firing or
flooded engine, can
cause three-way catalytic
converter or exhaust
system overheating.

NOTE: Unleaded fuel is
required for cars with

Replacing bulbs
pg. 81


Replacing bulbs

The method for replacement of bulbs in
the various lighting units is shown on the
following pages. Make sure when
installing bulbs, that the guide pin on the
socket fits into its corresponding recess.
When installing Halogen bulbs, do not
touch the glass with your fingers because
grease, oil or any other impurities can be
carbonized onto the bulb and damage the
reflector.
Use bulbs of correct type and voltage.
Failure to do so could cause the bulb
failure warning light to activate.

NOTE: Turn the ignition and light
switch off before replacing any bulbs.


Headlights (high/low beams)

1. Press the protruding tabs on the plastic
cover and pull out towards the fender.
2. Turn the bulb and connector 1/4 turn
counterclockwise and remove.
3. Remove the connector from the bulb.
4. Press a new bulb into the connector
without touching the bulb itself.
5. Reinsert the bulb into the headlight
housing and turn 1/4 turn clockwise until
the unit seats properly.
6. Reinstall the plastic cover.

Bulb Power US Bulb No.
High beam 70W HB3/9005
Low beam 60W HB4/9006

Headlight adjustment


The height of the headlight beams can be
adjusted according to vehicle load. The
headlights should be re-aimed if heavy
loads are carried in the trunk/cargo area or
rear seat, or when towing a trailer.
To adjust the headlights:
Park the car on a level surface and open
the hood.
The headlights are equipped with a level
which can be seen by looking through the
clear "window" on the top of the headlight
lens.
Turn the height adjustment knob (A) until
the bubble in the level aligns with within
the marking lines on the level.

Lateral headlight adjustment (B) should
only be carried out by an authorized
Volvo retailer. This setting should be
preset to "0".

Replacing tail light bulbs
(wagon models)

l Turn off the lights.
l Remove the cover with a screw driver.
l Rotate the bulb holder about 1/4" (0.6
cm) counterclockwise and remove the
holder from the tail light cluster.
l Gently press the bulb into the holder,
then rotate the bulb counterclockwise in
order to release it.
l Install a new bulb in the holder and
replace the bulb holder in the tail light
cluster. One of the guide lugs on the bulb holder
is slightly wider than the other two and,
thus, this lug fits into the widest recess
only.
l Turn the bulb holder clockwise
l Check that the bulb lights
l Re-install cluster cover

Two types of bulbs are in use
The guide lugs on the twin-pole bulb are
at different heights, and it is only possible
to fit these bulbs in one way. Try at first to
turn the bulb gently. Do not use force. If
this does not work, take out the bulb and
turn it half a turn and try again.

in the engine
compartment.

The fuse box
in the
passenger
compartment
(C) contains
the fuses
which protect
the various
functions in
the interior of
the car.
Fuse replacement

If an electrical component fails to function, it is likely that a fuse h\
as blown due to an
overloaded circuit. Pull out the fuse and look at it from the side to se\
e if there is a break
in the curved wire. If there is, install a new fuse of the same amperage\
and color.
Anumber of spare fuses are located in the fuse box in the passenger comp\
artment. There
is also a fuse removal tool to help with the removal and replacement of \
fuses.
Fuses pg. 90
Main fuse box (Box A)

Fuses in the main fuse box protect the entire
electrical system. If one of the fuses blows,
there is a serious electrical fault. Do not
change any of these fuses. Contact your
nearest Volvo workshop for a closer analysis.

When checking whether a fuse has blown, you
should first try to locate the blown fuse in the
fuse box in the passenger compartment or in
the relay/fuse box in the engine compartment.

Relay/fuse box (Box B)

The fuses in the relay/fuse box generally protect the electrical compone\
nts in the engine compartment.

The fuses are located under the cover in the relay/fuse box. Undo the fo\
ur clamps and pull out the fuse
you want to check. Look at the fuse from the side to see if there is a b\
reak in the curved wire. Should you
need to replace a fuse, you will find spare fuses in the central fuse bo\
x in the passenger compartment.
Replace the blown fuse with a new one of the same amperage and color. Ne\
ver use a fuse with a higher
amperage! There are a pair of pliers, to help when replacing fuses, in t\
he central fuse box in the passenger

In order to avoid interference and damage to your car's electrical syste\

connectors for the installation of a telephone and other electrical acce\
ssories. The two connectors are
located beneath the glove compartment behind the soundproofing panel.

When installing the accessories or the telephone, contact an authorized \
Volvo workshop.

extreme operating conditions such as trailer
towing in sustained ambient temperatures over

Servicing pg. 110
Torque exhaust and
intake manifold nuts


A loose manifold could alter air/
fuel ratio and cause an increase
in emissions and/or poor
driveability.

Air cleaner

Replace the air cleaner cartridge
with a new one every 30,000
miles (48,000 km). The
cartridge should be replaced
more often when driving under
dirty and dusty conditions, The
filter cannot be cleaned and,
therefore, should always be
replaced with a new one.

Vacuum fittings, hoses
and connections


Unstable idle, misfiring, or poor
emission control is often caused
by leaking vacuum hoses or
connections. Check hoses and
connections on distributor
vacuum unit, connections on
heater control servo systems and
hydraulic brake servo.
Fuel system cap, tank
and lines, and
connections


The effectiveness of the fuel
system to contain hydrocarbons
is dependent largely on a
leakfree system. Check for
proper sealing of gasoline filler
cap which contains "O" ring-
type seals. Check all
evaporative hoses in vehicle for
tightness. Check fuel lines under
vehicle and repair if necessary.

Fuel (line) filter

The fuel line filter is located
next to the fuel pump. This filter
should be replaced every
100,000 miles (160,000 km).
The filter is replaced as one
complete unit.
Replace more frequently if
contaminated fuel is introduced
into the tank (or if there is
reason to suspect that this has
occurred).

Timing belt

WARNING!
The distributor ignition
system operates at very high
voltages. Special safety
precautions must be followed
to prevent injury.
Always turn the ignition off
when:
l Replacing distributor
ignition components e.g.
plugs, coil, etc.
l Do not touch any part of
the distributor ignition system
while the engine is running.
This may result in unintended
movements and body injury.


Replacing spark plugs

The spark plugs should be
changed every 30,000 miles
(48,000 km). However, city
driving or fast highway driving
may necessitate changing after
15,000 miles (24,000 km) of
driving. When installing new
plugs, be sure to fit the right type
