1999 VOLVO S80 Owners Manual

Checking and correcting tire pressure
· Check the tire pressure when refuelling.
· The tire pressure should be corrected only when the tires are cold.
· With warm tires, correct only when the pressure is too low. The tire temperature rises after driving just a few miles.
Vehicle loading
The tires on your Volvo will perform to specifications at all normal loads when inflated as recommended on the tire
information label located on the inside of the fuel tankcover. This label lists both tire and vehicle design limits.
Do not load your car beyond the load limits indicated.
Temporary Spare (certain models)
The spare tire in your car is called a "Temporary Spare". It has the following designation: T125/80 R17.
Recommended tire pressure (see decal on fuel tank cover) should be maintained irrespective of which position on the
car the Temporary Spare tire is used on.
In the event of damage to this tire, a new one can be purchased from your Volvo retailer.WARNING!
Current legislation prohibits the use of the "Temporary Spare" tire other than as a temporary replacement for a
punctured tire. In other words, it must be replaced as soon as possible by a standard tire. Roadholding, etc., may be
affected with the "Temporary Spare" in use. Do not, therefore, exceed 50 mph (80 km/h).
CAUTION:
The car must not be driven with wheels of different dimensions or with a spare tire other than the one that came with
the car. The use of different size wheels can seriously damage your car's transmission.
NOTE: Certain models may be equipped with a full-size spare wheel.
pg. 83 Wheels and tires
Uniform tire quality grading
All passenger car tires must conform to Federal Safety Requirements in addition to these grades
TREADWEAR
The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions
on a specified government test course. For example, a tire graded 150 would wear one and one half (1 1/2) times as
well on the government course as a tire graded 100. The relative performance of tires depends upon the actual
conditions of their use, however, and many depart significantly from the norm due to variation in driving habits,
service practices and differences in road characteristics and climate.
TRACTION
ProCarManuals.com

The traction grades, from highest to lowest, are AA, A, B, and C, as measured under controlled conditions on specified
government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance.WARNING!
The traction grade assigned to this tire is based on braking (straight-ahead) traction tests and does not include
cornering (turning) traction.
TEMPERATURE
The temperature grades are AA (the highest), A, B, and C, representing the tire's resistance to the generation of heat
and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel.
Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive
temperature can lead to sudden tire failure. The grade C corresponds to a level of performance which all passenger car
tires must meet under the Federal Motor Safety Standard No. 109. Grades B and A represent higher levels of
performance on the laboratory test wheel than the minimum required by law. WARNING!
The temperature grade for this tire is established for a tire that is properly inflated and not overloaded. Excessive
speed, under-inflation, or excessive loading, either separately or in combination, can cause heat buildup and possible
tire failure.
pg. 84 Changing wheels
Insert flat end of lug wrench and turn/pull straight out
Changing wheels
The spare wheel is located under the carpet on the trunk floor. The jack and crank are secured in the wheel recess.
There are two jack attachment points on each side of the car.
To change a wheel:
· Engage the parking brake.
· Put the gear selector in (P)ark.
· Remove the wheel cap (where applicable) using the lug wrench in the tool kit.
· With the car still on the ground, use the lug wrench to loosen the wheel bolts 1/2 1 turn. Turn the bolts
counterclockwise to loosen.
ProCarManuals.com

Loosen wheel bolts
· Position the jack on the bar in the attachment (A in the illustration in right column) and crank while simultaneously
guiding the base of the jack to the ground. The base of the jack must be flat on a level, firm, non-slippery surface.
Before raising the car, check that the jack is still correctly positioned in the attachment.
· Raise the vehicle until the wheel to be changed is lifted off the ground.
· Unscrew the wheel bolts completely and carefully remove the wheel so as not to damage the thread on the studs.
Attaching the jack
NOTE: To avoid excessive wear and the necessity of rebalancing, mark and reinstall wheels in the same location and
position as before removal. To lessen the chance of imbalance, each wheel hub is equipped with a guide stud to ensure
that a removed wheel can be reinstalled in its original position (as when changing over to winter tires/wheels).
pg. 85 Changing wheels
Correct tightening order for wheel bolts
Installing the wheel
· Clean the contact surfaces on the wheel and hub.
· Lift the wheel and place it on the hub. Make sure that you align the wheel with the guide stud on the wheel hub prior
to installation.
· Install the wheel bolts crosswise (see illustration above) and tighten by turning lightly clockwise.
· Lower the vehicle to the ground and alternately tighten the bolts crosswise to 87 ft. lbs. (120 Nm).
· Install the wheel cap (where applicable).
WARNING!
ProCarManuals.com

· The jack must correctly engage the bar in the jack attachment (A). The car's weight must not rest on the jack
attachment (B). See illustration on page 84.
· Be sure the jack is on a firm, level, non-slippery surface.
· Never allow any part of your body to be extended under a car supported by a jack.
· Use the jack intended for the car when replacing a wheel. For any other job, use stands to support the side of the
car being worked on.
· Apply the parking brake and put the gear selector in the (P)ark position.
· Block the wheels standing on the ground, use rigid wooden blocks or large stones.
· The jack should be kept well-greased.
CAUTION:
· The car must not be driven with wheels of different dimensions or with a spare tire other than the one that came with
the car. The use of different size wheels can seriously damage your car's transmission.
· Correct tightening torque on wheel bolts must be observed. The wheel bolts should never be greased or lubricated.
The extended, chromed wheel bolts must not be used with steel rims, as they make it impossible to fit the hub caps.

Replacing fuses
If an electrical component fails to function, it is likely that a fuse has blown due to a temporary circuit overload.
The fuse boxes are located in three different places:
A - Relays/fuse box in the engine compartment *
B - Fuse box in the passenger compartment
C - Relays/fuse box in the trunk *
A label on the inside of each cover indicates the amperage and the electrical components that are connected to each
fuse.
The easiest way to see if a fuse is blown is to remove it. Pull the fuse straight out. If a fuse is difficult to remove, you
will find a special fuse removal tool in the passenger compartment fuse box. From the side, examine the curved metal
wire to see if it is broken. If so, put in a new
fuse of the same color and amperage (written on the fuse). Spare fuses are stored in the fuse box in the passenger
compartment. If fuses burn out repeatedly, have the electrical system inspected by an authorized Volvo retailer.
* The relays and main fuses in the engine compartment and trunk should only be replaced by an authorized
Volvo retailer. You can, however, replace the ordinary fuses if necessary.
pg.89 Fuses in the engine compartment
Relays/fuses in the engine compartment
The relay/fuse box in the engine compartment contains 8 main fuses and space for 21 ordinary fuses. The main fuses
should only be replaced by an authorized Volvo retailer. You can, however, replace the ordinary fuses if necessary.
Be sure to replace a blown fuse with a new one of the same color and amperage (written on the fuse).
