Volvo recommends the use of energy-conserving oils. Look for the API lab\
el. Synthetic or
semisynthetic oils may be used if their specifications comply with the o\
il quality requirements.
Volvo does not recommend oil additives, as they can adversely affect the\
engine.

Changing oil and oil filter

Oil and oil filter are first changed at the 600-1,200 mile (1,000-2,000\
km) service. Thereafter, changes
should be made as specified by this table:

Capacity

Including oil filter: 4.0 US qts = 3.85 litres
Check oil level when filling fuel.
SAE 15W/40 is recommended for use in driving conditions that raise oil t\
emperature and increase oil
consumption (i.e., mountain driving, trailer towing).

chart.

Volvo recommends the use of oils with the American Petroleum Institute (\
API) label. This
label certifies that the oil conforms to the applicable standards and sp\
ecifications of the
API.
If driving conditions include: Then the correct oil/oil filter change interval
is:
l Extended periods of idling and/or low-speed
operation
l Frequent short trips (less than 7 miles = 11 km)
l Extended periods of driving in dusty and/or sandy
areas
l Trailer towing
l Driving in mountainous areas EVERY 3 MONTHS
or 5,000 miles = 8,000 km
WHICHEVER COMES FIRST
l Primarily highway driving
l Frequent trips of longer than 7 miles = 11 km
EVERY 6 MONTHS
or 5,000 miles = 8,000 km

Cooling system

The risk of overheating is greatest, especially in hot weather, when:
- towing a trailer up steep inclines for prolonged periods at full throt\
tle, and at low engine rpm.
- idling for prolonged periods while the air conditioning system is in o\
peration.
- stopping the engine suddenly after high speed driving, so called after\
-boiling.
To avoid overheating. the following rules should be followed.
l Reduce speed and downshift when towing a trailer up long steep inclines.\
The risk of over heating can
be reduced by switching off the air conditioning system for a short whil\
e.
l Do not let the engine idle unnecessarily.
l Do not stop the engine immediately after high-speed driving, but allow t\
he engine to idle for 1/2 - 1
minute before switching off.
When the risk of overheating is imminent, or in the event of overheating\
, (the temperature gauge goes
repeatedly into, or stays continually in, the red section) the followin\
g precautions should be taken:
l Switch off the air conditioning system and switch the heater to full (m\
aximum) position.
l Stop the car and put the gear lever into neutral position-position N. Do\
not stop the engine!
l Increase the engine speed to approx. 2000 rpm (twice idling speed).
l Check the level of coolant in the expansion tank. Top-up, if necessary

Electrical System cautions

When changing the battery or when carrying out work involving the electr\
ical system, the following
should be observed:

1 A battery connection to the wrong terminal will damage the diodes. Bef\
ore connections are made,
check the polarity of the battery with a voltmeter.

2 If booster batteries are used for starting, they must be properly conn\
ected to prevent the diodes from
being damaged. For correct connection, see "Jump starting".

3 The battery leads should be disconnected any time the battery is being\
charged.
