2008 VOLVO S80 service

Do not allow oil to spill onto or come into contact with hot exhaust pipe surfaces.
NOTE
Synthetic oil is not used when the oil is changed at the normal maintenance intervals except at owner request and at
additional charge. Please consult your Volvo retailer.
214 06 Maintenance and specifications
Fluids
Coolant
Normally, the coolant does not need to be changed. If the system must be drained, consult a trained and qualified
Volvo service technician.
See page 275
for information on cooling system capacities.
CAUTION
Do not top off with water only. This reduces the rust-protective and antifreeze qualities of the coolant and has a
lower boiling point. It can also cause damage to the cooling system if it should freeze. Top off with Volvo Genuine
Coolant/Antifreeze only (a 50/50 mix of water and antifreeze).
The cooling system must always be kept filled to the correct level, and the level must be between the MIN and
MAX marks. If it is not kept filled, there can be high local temperatures in the engine which could result in damage.
Different types of antifreeze/coolant may not be mixed. Check coolant regularly.
WARNING
Never remove the radiator cap while the engine is warm. Wait until the vehicle cools.
If it is necessary to top off the coolant when the engine is warm, unscrew the expansion tank cap slowly so that
the overpressure dissipates.
215 06 Maintenance and specifications
Fluids
Brake fluid

Checking the level
The fluid reservoir is concealed under the round cover at the rear of the engine compartment. The round cover must be
removed first before the reservoir cap can be accessed.
The brake fluid should always be between the MIN and MAX marks on the inside of the reservoir. Check, without
removing the cap, that there is sufficient fluid in the reservoir.
Fluid type: DOT 4+ boiling point >536°F (280°C), P/N 9437433
Replace: The fluid should be replaced according to the intervals specified in the Warranty and Service Records
Information booklet.
When driving under extremely hard conditions (mountain driving, etc), it may be necessary to replace the fluid more
often. Consult a trained and qualified Volvo service technician.
Always entrust brake fluid changing to a trained and qualified Volvo service technician.
WARNING
If the fluid level is below the MIN mark in the reservoir or if a brake-related message is shown in the information
display: DO NOT DRIVE. Have the car towed to a trained and qualified Volvo service technician and have the brake
system inspected.
Filling
Turn and open the cover.
Unscrew the reservoir cap and fill the fluid. The level must be between the MIN and MAX marks.
Power steering fluid
Check the level frequently. The fluid does not require changing. The fluid level must be between the MIN and MAX

marks. For capacities and recommended fluid grade, see page 275.
WARNING
If a problem should occur in the power steering system or if the vehicle has no electrical current and must be towed,
it is still possible to steer the vehicle. However, keep in mind that greater effort will be required to turn the steering
wheel.
CAUTION
Keep the area around the power steering fluid reservoir clean when checking.

Replacing bulbs
Introduction
All bulb specifications are listed on page 223
. The following bulbs should only be replaced by a trained and qualified
Volvo service technician:
Dome lighting
Reading lights
Glove compartment lighting
Turn signals in the door mirror
Approach lighting in the door mirror
Brake lights
Active Bi -Xenon® and LED bulbs
WARNING
Active Bi -Xenon® headlights (option) - due to the high voltage used by these headlights, these bulbs should only
be replaced by a trained and qualified Volvo service technician.
Turn off the lights and remove the remote key from the ignition before changing any bulbs.
Headlight housing

The entire headlight housing must be lifted out when replacing all front bulbs (except for the fog lights).
CAUTION
Never touch the glass of bulbs with your fingers. Grease and oils from your fingers vaporize in the heat and will
leave a deposit on the reflector, which will damage it.
NOTE
Always switch off the ignition before starting to replace a bulb.
The optional Bi -Xenon® headlight bulbs contain trace amounts of mercury. These bulbs should always be
disposed of by a trained and qualified Volvo service technician.
Removing the headlight housing
1. Switch off the ignition by pressing quickly on the START/STOP ENGINE button and remove the remote key from
the ignition slot
1.
2. (Upper illustration)
Withdraw the headlight housing's locking pins.
Pull the headlight housing straight out.
3. (Lower illustration)
Unplug the wiring connector by holding down the clip with your thumb.
Pull out the connector with the other hand.

Wiper blades and washer fluid
Wiper blades
The wiper blades are different lengths. The blade on the driver's side is longer than the blade on the passenger side.
Service position
The wiper blades must be in the service (vertical) position for replacement or washing.
1. Switch off the ignition (ignition mode 0, see page 80
) and keep the remote key in the ignition slot1.
2. Move the right steering wheel lever up and hold it for at least 1 second. The wipers will then move to the vertical
position on the windshield.

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.

Filling washer fluid

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.
227 06 Maintenance and specifications
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.

Changing

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.
