maintenance VOLVO S80 2008 Owner's Guide

The wipers will return to the normal position when the vehicle is started.
1Does not apply to vehicles with the optional keyless drive.
Replacing the wiper blades
With the wipers in the service position, fold out the wiper arm from the windshield. Press the button on the wiper
blade attachment and pull the wiper blade straight out, parallel with the wiper arm.
Slide in the new wiper blade until it clicks into place.
Check that the blade is securely in place.
Cleaning
Keeping the windshield and wiper blades clean helps improve visibility and prolongs the service life of the wiper
blades. Clean the wiper blades with a stiff-bristle brush and lukewarm soap solution or car washing detergent.

Wiper blades and washer fluid
Filling washer fluid

The windshield and headlight washers share a common reservoir.
The washer fluid reservoir is located on the driver's side of the engine compartment. During cold weather, the reservoir
should be filled with windshield washer solvent containing antifreeze. For capacities, see page 275
.

Battery
Warning symbols on the battery
NOTE
A used battery should be disposed of in an environmentally responsible manner. Consult your Volvo retailer or take
the battery to a recycling station.
Handling
Check that the battery cables are correctly connected and tightened.
Never disconnect the battery when the engine is running (for example, when replacing the battery).

The service life and function of the battery is influenced by factors such as the number of starts, discharging, driving
style, driving conditions, climatic conditions etc.
Never use a quick charger to charge the battery.
WARNING
Never expose the battery to open flame or electric spark.
Do not smoke near the battery.
Battery fluid contains sulfuric acid. Do not allow battery fluid to contact eyes, skin, fabrics or painted surfaces. If
contact occurs, flush the affected area immediately with water. Obtain medical help immediately if eyes are affected.
NOTE
The life of the battery is shortened if it becomes discharged repeatedly.

Battery
Maintenance
Regularly check that the electrolyte level is correct and never fill above the level mark.
Check all cells. Use a large screwdriver or a coin to remove the cell caps. Each cell has its own maximum and
minimum level mark.
If necessary, top up with distilled water to the battery's maximum mark.
Tighten the cell caps thoroughly.
CAUTION
Always use distilled or deionized water (battery water).
Never fill above the level mark in the cell.

Fuses
Replacing fuses
There are relay/fuse boxes located in the engine compartment, the passenger compartment, and the trunk.
If an electrical component fails to function, this may be due to a blown fuse. The easiest way to see if a fuse is blown
is to remove it.
To do so:
1. Pull the fuse straight out. If a fuse is difficult to remove, special fuse removal tools are located on the inside of the
fuse box covers.
2. From the side, examine the curved metal wire in the fuse to see if it is intact.
If the wire is broken, insert a new fuse of the same color and amperage (written on the fuse).
If fuses burn out repeatedly, have the electrical system inspected by a trained and qualified Volvo service technician.
WARNING
Never use metal objects or fuses with higher amperage than those stated on the following pages. Doing so could
seriously damage or overload the vehicle's electrical system.

Wheels and tires
Introduction
Your vehicle is equipped with tires according to the vehicle's tire information placard on the B-pillar (the structural
member at the side of the vehicle, at the rear of the driver's door opening).
The tires have good road holding characteristics and offer good handling on dry and wet surfaces. It should be noted
however that the tires have been developed to give these features on snow/ice-free surfaces.
Certain models are equipped with "all-season" tires, which provide a somewhat higher degree of road holding on
slippery surfaces than tires without the "all-season" rating. However, for optimum road holding on icy or snow-
covered roads, we recommend suitable winter tires on all four wheels.
When replacing tires, be sure that the new tires are the same size designation, type (radial) and preferably from the
same manufacturer, on all four wheels. Otherwise there is a risk of altering the car's roadholding and handling
characteristics.
Storing wheels and tires
When storing complete wheels (tires mounted on rims), they should be suspended off the floor or placed on their sides
on the floor.
Tires not mounted on rims should be stored on their sides or standing upright, but should not be suspended.
CAUTION
Tires should preferably be stored in a cool, dry, dark place, and should never be stored in close proximity to
solvents, gasoline, oils, etc.
Tread wear indicator

The tires have wear indicator strips running across or parallel to the tread. The letters TWI are printed on the side of
the tire. When approximately 1/16" (1.6 mm) is left on the tread, these strips become visible and indicate that the tire
should be replaced. Tires with less than 1/16" (1.6 mm) tread offer very poor traction.
When replacing worn tires, it is recommended that the tire be identical in type (radial) and size as the one being
replaced. Using a tire of the same make (manufacturer) will prevent alteration of the driving characteristics of the
vehicle.
WARNING
The wheel and tire sizes for your Volvo are specified to meet stringent stability and handling requirements.
Unapproved wheel/tire size combinations can negatively affect your vehicle's stability and handling. Approved tire
sizes are shown in the Tire inflation pressure tables beginning on page 240
.
Any damage caused by installation of unapproved wheel/tire size combinations will not be covered by your new
vehicle warranty. Volvo assumes no responsibility for death, injury, or expenses that may result from such
installations.

Wheels and tires
New tires
Remember that tires are perishable goods. As of 2000, the manufacturing week and year (Department of
Transportation (DOT) stamp) will be indicated with 4 digits (e.g. 1502 means that the tire illustrated was manufactured
during week 15 of 2002).
Tire age
Tires degrade over time, even when they are not being used. It is recommended that tires generally be replaced after
6 years of normal service. Heat caused by hot climates, frequent high loading conditions or Ultra Violet (U.V.)
exposure can accelerate the aging process.
You should replace the spare tire when you replace the other road tires due to the aging of the spare.
A tire's age can be determined by the DOT stamp on the sidewall (see the illustration).
A tire with e.g., visible cracks or discoloration should be replaced immediately.
Improving tire economy
Maintain correct tire pressure. See the tire pressure tables beginning on page 240.
Drive smoothly: avoid fast starts, hard braking and tire screeching.
Tire wear increases with speed.
Correct front wheel alignment is very important.
