The gauge pointer must not go down to the red
field while driving.
Do not continue to drive the car with the pointer in
the red zone.
Note: While idling with a hot engine the pointer
may go into the red field. This is not a cause for
concern providing the pointer rises to the normal
driving range again when you increase the engine
speed. should be within the black field.
Should the pointer point to the upper or lower red
field when driving, this may indicate some fault in
the electrical system.
Note: While idling with a hot engine (especially
with air conditioning ON), the pointer may
indicate low voltage. This is not a cause for
concern provided that the indicated voltage
increases when you increase engine speed.

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.

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.
