Winter driving pg. 69
Cold weather precautions
l If you wish to check your car before the
approach of cold weather, the following advice is
worth noting:
Make sure that the engine coolant contains at least
50 percent antifreeze: that is, 5.3 qts. (5 liters)
Volvo Genuine Coolant/Antifreeze. This gives
protection against freezing down to -31°F (-35°
C). See section "Coolant".
The use of "recycled" antifreeze is not approved
by Volvo. Different types of antifreeze may not be
mixed.
l Try to keep the fuel tank well filled - this
prevents the formation of condensation in the
tank.
In addition in extremely cold weather conditions it
is worthwhile to add fuel line de-icer before
refueling.
l The viscosity of the engine oil is important. Oil
with low viscosity (thinner oil) improves cold-
weather starting as well as decreasing fuel
consumption while the engine is warming up. For
winter use, 5W-30 oil, particularly the synthetic
type, is recommended.
Be sure to use good quality oil but do not use this

l The Volvo Washer Solvent should be diluted as
follows:
Down to 14°F (-10°C): 1 part anti-freeze and 4
parts water
Down to 5°F (-15°C): 1 part anti-freeze and 3
parts water
Down to 0°F (-18°C): 1 part anti-freeze and 2
parts water
Down to -18°F (-28°): 1 part anti-freeze and 1
part water
l Use lock spray or grease in the locks.

NOTE: Avoid the use of de-icing spray as they
can cause damage to the locks.

Automatic differential lock (certain
models)


The differential automatically locks at speed
between 3 - 25 mph (5 - 40 km/h) if either of the
drive wheels begins to lose traction. The
differential lock improves power distribution to
the drive wheels in slippery conditions, shifting
power to the wheel with best traction. It also

cold-weather oil for hard driving or in warm
weather. See section "Engine oil" for more
information.
l The load placed on the battery is greater during
the winter since the heater, windshield wipers,
lighting etc. are used more often. Moreover, the
capacity of the battery decreases as the
temperature drops. In very cold weather, a poorly
charged battery can freeze and be damaged. It is
therefore advisable to check the state of charge
more frequently and spray an anti-rust oil on the
battery posts.
l Volvo recommends the use of snow tires on all
four wheels for winter driving - see section
"Wheels and tires".
l To prevent the washer reservoir from freezing,
add washer solvents containing antifreeze. This is
important since dirt is often splashed on the
windshield during winter driving, thus requiring
frequent use of the washers and wipers.
functions when the transmission is in reverse.
Also see "Winter/Wet" mode on page 59.

*These positions always offer the kick-down
feature.
Long distance trip pg. 70


Before a long distance trip

It is always worthwhile to have your car checked at a Volvo retailer
before driving long distances. Your retailer will also be able to supply\

you with bulbs, fuses, spark plugs and wiper blades for your use in the \
event that problems occur.

If you prefer to check the car yourself, please note the following:
l Check that the engine runs smoothly and that fuel consumption is
normal.
l Check engine oil, coolant levels, and for possible fuel leakage.
l Check transmission oil level and rear axle for leakage.
l Check condition of drive belts.
l Check state of charge of battery.
l Examine tires carefully (the spare tire as well), and replace those
that are worn. Check tire pressures.
l The brakes, front wheel alignment, and steering gear should be
checked by your Volvo retailer only.
l Check all lights, including high beams.

cleaning improves visibility
considerably.
l Wash off the dirt from the
underside (wheel housings fenders,
etc.).
l In areas of high industrial fallout,
more frequent washing is
recommended.

CAUTION: During high pressure
washing, the spray mouth piece
must never be closer to the vehicle
than 13" (30 cm). Do not spray
into the locks.


l When washing or steam cleaning
the engine, avoid spraying water or
steam directly on the electrical
WARNING!
When the car is driven immediately after being washed,
apply the brake several times in order to remove any
moisture from the brake linings.
Engine cleaning agents should not be used when the engine
is warm. This constitutes a fire risk.




NOTE: When washing the car, remember to remove dirt from
the drain holes in the doors and sills. Bumpers: Wash the
bumpers with the same cleaning agent used on the rest of the
car. Never clean the bumpers with gasoline or paint thinner.
Difficult spots can be removed with denatured alcohol. To
avoid scratches, do not dry the bumpers with paper.

*Pay special attention to the drain holes at the base of the
windshield in the cowl under the rear edge of the hood.

Chapter 8 - (cont.)Engine oil
pg. 108
Checking the oil level

The oil level should be checked every
time the car is refuelled. This is
especially important during the engine
break-in period (up to the first service).

CAUTION: Not checking the oil level
regularly can result in serious engine
damage if the oil becomes too low.


Be sure the oil level is maintained between
the upper and lower marks on the dipstick.
Low oil level can cause internal damage to
the engine and over-filling can result in
high oil consumption. The distance
between the dipstick marks represents
approx. 1 US qt (1 liter) of oil. Before
checking the oil level after the car has been
driven, park the car on a level surface and
wait at least 5 minutes after the engine has
been switched off. The oil level should be
halfway between the MIN and MAX
marks.
If the oil is checked before the car is driven
(engine completely cold) the oil level
should be at the MAX mark.

NOTE: The engine must be stopped when
checking the oil.

Draining the oil

Drain the oil after driving while it is still
warm.

WARNING! The oil may be very
hot.
To add or change engine oil

Add oil of the same kind as already used.
Capacity (including filter): 5.9 US qts = 5.75 liters

Changing oil filter



Replace the oil filter at every oil change



WARNING! Oil spilled on a hot exhaust pipe
constitutes a fire risk.

If you change the engine oil and filter
yourself, your Volvo retailer can assist you
in disposing of the used oil. Engine oil can
be harmful to your skin - gloves should
worn when performing this work.
Engine oil pg. 109
Oil quality

Meeting API specification SG, SG/CD, SH or
Energy Conserving (EC) II
For best fuel economy and engine protection
consult with your authorized Volvo retailer for
recommended oils. Oils with a different quality
rating may not provide adequate engine
protection.

Viscosity (stable ambient
temperatures):




Do not use oils with other viscosity ratings. The
use of incorrect viscosity oil can shorten engine
life.
Volvo recommends the use of energy-conserving
oils. Look for the API label. Synthetic oils
complying with oil quality requirements are
recommended for: driving in areas of sustained
temperature extremes (hot or cold), when towing
a trailer over long distances or for prolonged
driving in mountainous areas.
Extra oil additives must not be used unless
advised by an authorized Volvo retailer.

NOTE: SAE 15W/40 should only be used in


Changing oil and oil filter

Oil and oil filter changes should be made as
specified in the following table:

If driving conditions

extreme operating conditions such as trailer
towing in sustained ambient temperatures over
104° F (40° C). However, SAE 10W-30 synthetic
oil would be a better alternative in such
conditions.
SAE 15W-40 should not be used under normal
operating conditions.

(API) labels. These labels certify
the oil conforms to the applicable
standards and specifications of
the API.
Servicing pg. 110
Torque exhaust and
intake manifold nuts


A loose manifold could alter air/
fuel ratio and cause an increase
in emissions and/or poor
driveability.

Air cleaner

Replace the air cleaner cartridge
with a new one every 30,000
miles (48,000 km). The
cartridge should be replaced
more often when driving under
dirty and dusty conditions, The
filter cannot be cleaned and,
therefore, should always be
replaced with a new one.

Vacuum fittings, hoses
and connections


Unstable idle, misfiring, or poor
emission control is often caused
by leaking vacuum hoses or
connections. Check hoses and
connections on distributor
vacuum unit, connections on
heater control servo systems and
hydraulic brake servo.
Fuel system cap, tank
and lines, and
connections


The effectiveness of the fuel
system to contain hydrocarbons
is dependent largely on a
leakfree system. Check for
proper sealing of gasoline filler
cap which contains "O" ring-
type seals. Check all
evaporative hoses in vehicle for
tightness. Check fuel lines under
vehicle and repair if necessary.

Fuel (line) filter

The fuel line filter is located
next to the fuel pump. This filter
should be replaced every
100,000 miles (160,000 km).
The filter is replaced as one
complete unit.
Replace more frequently if
contaminated fuel is introduced
into the tank (or if there is
reason to suspect that this has
occurred).

Timing belt

WARNING!
The distributor ignition
system operates at very high
voltages. Special safety
precautions must be followed
to prevent injury.
Always turn the ignition off
when:
l Replacing distributor
ignition components e.g.
plugs, coil, etc.
l Do not touch any part of
the distributor ignition system
while the engine is running.
This may result in unintended
movements and body injury.


Replacing spark plugs

The spark plugs should be
changed every 30,000 miles
(48,000 km). However, city
driving or fast highway driving
may necessitate changing after
15,000 miles (24,000 km) of
driving. When installing new
plugs, be sure to fit the right type
