Checking and correcting tire pressure
Check the tire pressure when refueling. The tire pressure should only be\
corrected when the tires are
cold. With warm tires, correct only when the pressure is too low. The ti\
re temperature (and, thus,
pressure) rises after driving just a few miles.
Warning: Improperly inflated tires will reduce tire life, adversely affe\
ct vehicle handling and can
possibly lead to failure resulting in loss of vehicle control without pr\
ior warning.
Vehicle Loading
The tires on your Volvo will perform to specifications at all normal loa\
ds when inflated as
recommended on the tire information label located on the rear facing sid\
e of the right front door. This
label lists both tire and vehicle design limits.
Do not load your car beyond the load limits indicated.
Tire Pressure Label
The tire pressure label is located on the rear facing side of the right \
front door.
See section titled ''Specifications'' and Consumer Information Booklet f\
or complete tire pressure
information.
Wear indicator
The tires have a so-called "wear indicator in the form of a number of na\
rrow strips running across or
parallel to the tread. When approx 1/16 " (1.5 mm) is left on the trea\
d, these strips show up and indicate
the tire should be replaced.
Tires with less than 1/16" (1.5 mm) tread have a very poor grip in rai\
n or snow.

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).

Volvo 1990 240 Model
During the winter, multigrade oil 10W-30 should be used in the engine. \
The viscosity of the engine oil is important. Oil with low viscosity (t\
hinner oil) improves cold-weather
starting as well as decreasing fuel consumption while the engine is warm\
ing up. To avoid difficult cold
start conditions (during extreme winter weather), use of 5W-30 oil, pa\
rticularly the synthetic type, is
recommended.
Be sure to use good quality oil but do not use this cold-weather oil for\
hard driving or in warm weather.
See section "Engine oil" for more information.
Electrical system
The electrical system is subject to greater stresses during the winter. \
Lighting and starter motor are used
more often. The battery capacity is reduced at low air temperature. The \
state of charge must be checked
more frequently, and if necessary the battery should be recharged. The b\
attery can freeze if the state of
charge is too low.
Windshield washers
Anti-freeze washer fluid should also be added to the washer fluid contai\
ner for the windshield and rear
window (tailgate, wagon model) washer.
This is particularly important during the winter because the windshield \
frequently becomes dirty and is
often splashed with water which freezes rapidly. This may necessitate th\
e frequent use of the windshield
washer and wipers. Your Volvo dealer can supply you with suitable anti-f\
reeze for this purpose. Suitable
mixtures of anti-freeze and water are:
Down to +14 ° F (-10 ° C) 1 part anti-freeze 4 parts water.
Down to + 7 ° F (-14 ° C) 1 part anti-freeze 3 parts water.
Down to 0 ° F (-18 ° C) 1 part anti-freeze 2 parts water.
Down to -18 ° F (-28 ° C) 1 part anti-freeze 1 part water.
Use Volvo Teflon lock spray or grease in the locks. They can be purchase\
d from your Volvo dealer
Note: Avoid the use of de-icing sprays as they can cause damage to the
locks.
pg. 92 Service diagnosis
The diagnoses outlined below are intended to serve only as a guide to lo\
cate and temporarily correct
minor faults. Causes of unsatisfactory performance should be investigate\
d and corrected by your Volvo

Possible cause Correction
Intake system leaking. Check vacuum hose connections at manifold and
auxiliary air valve.
No fuel reaching engine. Check for fuel in the tank.
Check fuse No 4.
