Starting (ignition) switch/steering wheel lock

O Locked position: remove the key to lock the steering wheel.
I Intermediate position: certain circuits (heater blower, cigarette lig\
hter, accessories, etc.) on.
II Drive position: key position when engine is running.
III Starting position: release the key when engine starts. The key retur\
ns automatically to
drive position.
The steering wheel lock may be under tension when the car is parked. Tur\
n the steering wheel slightly to
free the ignition key.
A chime will sound if the starting key is in the ignition lock and the f\
ront door on the driver's side is
open. The chime will also sound if the headlights or parking lights are \
on when the door is open. The

Seat heaters

The front seats are equipped with electrically-heated backrests and seat\
cushions. The switches engage
the heating which then is thermostatically controlled. It switches on au\
tomatically when the temperature
drops below 60°F (15°C) and switches off at approx. 95°F (35\
°C). pg. 20 Cigarette lighter, Ash trays

Cigarette lighter

To operate, depress the knob fully. When the knob automatically releases\
, the cigarette lighter is ready
for use.
The starting (ignition) switch must be ON for the cigarette lighter to\
function.

Changing coolant

Every two years or 30,000 miles (48,000 km) the cooling system should \
be drained, flushed and refilled.
Remove the expansion tank cap. Open the drain cock on right side of the \
engine block and disconnect
the lower radiator hose.

Fill coolant through the expansion tank.
The heater controls should be fully open when draining and filling.
Add coolant until the level is up to the MAX mark or slightly above.

Start engine and run until hot. Check the cooling system connections for\
tightness. Also re-check the
coolant level. Capacity: 9.9 US qts. = 9.4 liters (manual transmission \
models); 9.7 US qts = 9.2 liters
(automatic transmission models)

Engine Mechanical Components

Torque manifold nuts

The manifold nuts should be torqued at the 600-1,200 mile (1,000-2,000 \
km) inspection. A loose
manifold could alter air/fuel ratio and cause an increase in emission an\
d/or poor driveability.

Valves

The valve clearance should be checked every 30,000 miles (48,000 km). \

Vacuum fittings, hoses and connections

Unstable idle, misfiring or poor emission control is often caused by lea\
king vacuum hoses or
connections. Check hoses and connections on distributor vacuum unit, EGR\
valve (where applicable)
and connections on heater control servo systems and hydraulic brake serv\
o.

Exhaust Gas Recirculation (EGR)

This system operates by returning some of the exhaust gases to the engin\
e to be recombusted: since this
lowers the combustion temperature the amount of nitrogen oxides released\
into the atmosphere is
reduced.
The EGR valve should be cleaned at the 60,000 mile inspection and therea\
fter cleaned every 25,000
miles (40,000 km).

Timing belt

The timing belt tensioner should be adjusted at the 600-1,200 mile (1,0\
00-2,000 km) inspection.

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.

Replacing fuses

The fuse box is positioned in front of the left front door pillar. When \
replacing fuses, check that the
correct amperage is used.
Never use fuses of higher amperage. unless specified by your Volvo deale\
r. If one fuse repeatedly fails,
take the car to your Volvo dealer for fault tracing.
A spare fuse kit is available from your Volvo dealer.
