How to use the air conditioner:
1
Fan
Position 4 for rapid cooling.
2 AIR COND
Start the air conditioning compressor by turning the control knob clockw\
ise toward MAX.
For rapid cooling, position the knob into the orange range beyond MAX. A\
fter desired temperature is
reached re-position the control knob into the blue range.
At cruising speeds, the knob should be kept within the blue range. If it\
remains in the orange range, icing
may occur resulting in decreased cooling capacity.
3
Recirculation
Push in for rapid cooling and during high humidity conditions.
4 TEMP
When using the air conditioner for cooling, the TEMP control should be s\
et to COOL position, fully left.
Use the AIR COND control to regulate the temperature.
To obtain rapid cooling, all windows must be closed and buttons
and out. Cool air will then be
discharged through the four dash outlets which should be fully open.
Note: For rapid removal of condensation from inside glass surfaces, the \
air conditioner can be
switched on even when not required for interior cooling. The air conditi\
oner will dehumidify the air
inside the vehicle.
Have your Volvo dealer check the system for correct operation yearly. Th\
e air conditioning system
should be operated periodically to ensure trouble-free performance year \
round.

Checking oil level
The oil level should be checked each time the fuel tank is refilled. Be \
sure the oil level is maintained
between the upper and lower marks on the dipstick. Low oil level can cau\
se internal damage to the
engine and overfilling can result in high oil consumption. The distance \
between the dipstick marks
represents approx. 1 quart (1 liter) of oil.
Changing oil filter
Replace the oil filter at every oil change. If the oil filter is changed\
separately, 1/2 US qt = 1/2 liter of oil
should be added.
To add oil or change oil
Add oil of the same kind as already used. See engine oil section.
Note: Allow engine to cool before changing
oil.
Coolant
Maintain fluid level between MAX and MIN marks on expansion tank. Mixtur\
e of 50 percent Volvo
antifreeze type C (blue-green) or similar and 50 percent water should \
be used. See "Coolant" section.

pg. 91 Long distance trips, Cold weather
Prior to a long distance trip
Have your car checked at a Volvo dealer. Preventive maintenance will hel\
p to ensure a trouble free trip.
Remember to take along a Volvo dealer directory.
The main items to check are listed below:
1. Brakes, front wheel alignment and steering gear.
2. Engine running condition.
3. Fuel system operation.
4. Oil leaks: engine, transmission, rear axle.
5. Cooling system for leaks or worn hoses.
6. Examine tires carefully, replace worn tires.
7. Battery and terminals.
8. Tool equipment.
9. Lighting.
10. Drive belts, for tightness and wear.
11. All fluid levels.
Cold weather/Engine fuel system
During the winter, large variations in temperature cause condensation to\
form in the fuel tank and can
impair the running of the engine. This can be reduced by adding dry gas \
to the fuel. There is less risk of
condensation forming in the fuel tank if it is kept full or nearly full.\
Engine cooling system
Volvo type C (blue-green) coolant should be used all year round. The c\
ooling system should always
contain water plus anti-freeze and rust inhibitor, even during the summe\
r. Experience has also shown
that extremely weak anti-freeze solutions (10-25 percent) are ineffect\
ive for rust protection. For this
reason, the quantity of antifreeze/summer coolant should be about 50 per\
cent of the solution. This
lowers the freezing point to - 30 ° F (-35 ° C).

dealer.
Condition: Starter fails to operate (or operates very slowly)
Possible cause Correction
Weak battery or dead cell. With the starting (ignition) switch in the "Driving"
or "On" position, check to see if the warning lights
on the dashboard come on and if they stay on when
the starter is engaged. If the lights do not come on or
if they go off when the starter is engaged, the battery
is discharged or see below.
Loose or corroded battery cable terminals. Check battery terminals and clamps. Clean or
replace if necessary. Check that the starter cable is
secure at its terminals.
The ground strap, which connects the battery
negative (-) terminal to the engine, should also be
checked for corrosion or looseness.
Open circuit between starting (ignition) switch
and starting (ignition) switch terminal on
starter. The circuit is closed if a clicking sound is heard
from the starter when it is engaged. If no clicking
sound is heard, check that the blue wire at the starter
is secure. If still no clicking sound is heard, the
starting (ignition) switch or the wire is defective.
Starter motor defective. If the above checks have been performed, and no
fault is evident, the starter may be defective. NOTE:
In this case the headlight intensity will not dim when
the starter is engaged.
