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\
m, your car is supplied with two
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
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.
American Petroleum Institute
(API) labels. These labels certify
the oil conforms to the applicable
standards and specifications of
the API.
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
