service VOLVO S80 2008 Repair Manual

NOTE
TPMS indicates low tire pressure but does not replace normal tire maintenance. For information on correct tire
pressure, please refer to the tables beginning on page 240
, or consult your Volvo retailer.
The tire pressure warning light will not identify which tire is under-inflated. Be sure to check all four tires.
A certain amount of air seepage from the tires occurs naturally and tire pressure fluctuates with seasonal changes
in temperature. Always check tire pressure regularly.
Erasing warning messages
When a low tire pressure warning message has been displayed, and the tire pressure warning light has come on:
1. Use a tire pressure gauge to check the inflation pressure of all four tires.
2. Re-inflate the tire(s) to the correct pressure (consult the tire pressure placard or the tables beginning on page 240
).
3. In certain cases, it may be necessary to drive the vehicle for several minutes at a speed of 20 mph (30 km/h) or
faster. This will erase the warning text and the warning light will go out.
WARNING
Incorrect inflation pressure could lead to tire failure, resulting in a loss of control of the vehicle.
Changing wheels with TPMS
Please note the following when changing or replacing the factory installed TPMS wheels/tires on the vehicle:
Only the factory-mounted wheels are equipped with TPMS sensors in the valves.
If the vehicle is equipped with a temporary spare tire, this tire does not have a TPMS sensor.
If wheels without TPMS sensors are mounted on the vehicle, TIRE PRESS SYST SERVICE REQUIRED will be
displayed each time the vehicle is driven above 25 mph (40 km/h) for 10 minutes or more.
Once TPMS sensors are properly installed, the warning message should not reappear. If the message is still
displayed, drive the vehicle for several minutes at a speed of 20 mph (30 km/h) or faster to erase the message.
Volvo recommends that TPMS sensors be fitted on all wheels used on the vehicle. Volvo does not recommend
moving sensors back and forth between sets of wheels.
NOTE
If you change to tires with a different recommended inflation pressure, the TPMS system must be recalibrated to
these tires. This must be done by a trained and qualified Volvo service technician.
If a tire is changed, or if the TPMS sensor is moved to another wheel, the sensor's seal, nut, and valve core should
be replaced.
When installing TPMS sensors, the vehicle must be parked for at least 15 minutes with the ignition off. if the
vehicle is driven within 15 minutes, a TPMS error message will be displayed.
CAUTION
When inflating tires with TPMS valves, press the pump's mouthpiece straight onto the valve to help avoid bending or
otherwise damaging the valve.

Tire sealing system
Certain models are equipped with a tire sealing system that enables you to temporarily seal a hole in the tread surface
and reinflate a flat tire, or to adjust a tire's inflation pressure.
The system consists of an air compressor, a container for the sealing compound, wiring to connect the system to the
vehicle's electrical system via one of the 12-volt sockets, and a hose used to connect the system to the tire's inflation
valve.
The 12-volt sockets are located in the front tunnel console, on the rear side of the center console in the rear seat. See
page 185
.
Accessing the tire sealing system
The tire sealing system is stowed under the floor of the trunk. To access it:
1. Fold up the floor carpeting, starting at the rear and working forward.
2. Remove the retaining screws
3. Lift out the foam plastic block holding the jack and lug wrench.
4. Lift out the tire sealing system.
NOTE
The tire sealing system is only intended to seal holes on the tire's tread area, not the sidewall.
Tires with large holes or tears cannot be repaired with the tire sealing system.
WARNING
After using the tire sealing system, the vehicle should not be driven farther than approximately 120 miles (200
km).
Have the tire inspected by a qualified service technician as soon as possible to determine if it can be permanently
repaired or must be replaced.
The vehicle should not be driven faster than 50 mph (80 km/h) while using a tire that has been temporarily
repaired with the tire sealing system.
After using the tire sealing system, drive carefully and avoid abrupt steering maneuvers and sudden stops.

Tire sealing system -overview

Contact with the sealing compound may cause skin irritation. If contact occurs, wash the affected area immediately
with soap and water.
5. Unscrew the orange cover over the bottle holder and unscrew the cap on the bottle of sealing compound.
NOTE
Do not break the seal on the bottle. This occurs automatically when the bottle is screwed into the holder.
6. Screw the bottle into the bottle holder.
WARNING
The bottle is equipped with a catch to keep it securely in place and help prevent sealing compound leakage. Once in
place, the bottle cannot be unscrewed. This must be done by a trained and qualified Volvo service technician.
7. Remove the valve cap from the tire's inflation valve and screw the tire sealing system's hose connector onto the
valve as tightly as possible by hand.

8. Connect the electrical wire to the nearest 12-volt socket in the vehicle.
9. Start the vehicle's engine.
WARNING
The vehicle's engine should be running when the tire sealing system is used to avoid battery drain. Therefore, be sure
the vehicle is parked in a well ventilated place, or outdoors, before using the system.
10. Start the tire sealing system's compressor by pressing the on/off switch to position I .
WARNING
Never stand next to the tire being inflated when the compressor is in operation.
If cracks, bubbles, etc. form on the tire, switch off the compressor immediately.
If there is visible damage to the sidewall or the rim, the tire cannot be repaired. The vehicle should not be driven if
this occurs. Contact a towing service or Volvo On Call Roadside Assistance if applicable.
NOTE
The air pressure gauge will temporarily show an increase in pressure to approximately 88 psi (6 bar) while the
sealing compound is being pumped into the tire. The pressure should return to a normal level after approximately 30
seconds.
11. Within seven minutes, inflate the tire to between 22-44 psi (1.8-3.0 bar). Switch off the compressor briefly to get a
clear reading from the pressure gauge.

CAUTION
The compressor should not be used for more than 10 minutes at a time to avoid overheating.
WARNING
If the pressure remains below 22 psi (1.8 bar) after approximately seven minutes, turn off the compressor. In this
case, the hole is too large to be sealed and the vehicle should not be driven.
12. Switch off the compressor and disconnect the electrical wire from the 12-volt socket.
13. Unscrew the hose from the tire's inflation valve and reinstall the valve cap.
14. Immediately drive the vehicle for approximately 2 miles (3 km) at a maximum speed of 50 mph (80 km/h) to
distribute the sealing compound in the tire.
NOTE
Safely stow the tire sealing system in a convenient place as it will soon be used again to check the tire's inflation
pressure.
The empty bottle of sealing compound cannot be removed from the bottle holder. Consult a trained and qualified
Volvo service technician to have the bottle removed and properly disposed of.
WARNING
If heavy vibrations, unsteady steering behavior, or noises should occur while driving, reduce speed and park the
vehicle in a safe place. Recheck the tire for bumps, cracks, or other visible damage, and recheck its inflation
pressure. If the pressure is below 19 psi (1.3 bar), do not continue driving. Have the vehicle towed to a trained and
qualified Volvo service technician.

Stage 2: Checking inflation pressure
1. Connect the tire sealing system as described in stage 1.
2. Refer to the tables on pages 240 and 241
for the correct tire inflation pressure. If the tire needs to be inflated, start
the tire sealing system's compressor. If necessary, release air from the tire by turning the air release knob
counterclockwise.
CAUTION
The compressor should not be used for more than 10 minutes at a time to avoid overheating.
WARNING
If you interrupt your trip for more than 1 hour, check the inflation pressure in the damaged tire again before
continuing.

Replacing the sealing compound container
The sealing compound container must be replaced if:
the tire sealing system has been used to repair a tire
the container's expiration date has passed (see the date on decal).
NOTE
After use, the sealing compound bottle, the hose, and certain other system components must be replaced. Please
consult your Volvo retailer for replacement parts.
If the sealing compound bottle's expiration date has passed, please take it to a Volvo retailer or a recycling station
that can properly dispose of harmful substances.

Vehicle care
Washing the car
WARNING
Be sure that the compressor is not connected to a 12-volt socket while replacing the container.
The following points should be kept in mind when washing and cleaning the car:
The car should be washed at regular intervals since dirt, dust, insects and tar spots adhere to the paint and may cause
damage. To help prevent corrosion, it is particularly important to wash the car frequently in the wintertime.
Avoid washing your car in direct sunlight. Doing so may cause detergents and wax to dry out and become abrasive.
To avoid scratching, use lukewarm water to soften the dirt before you wash with a soft sponge, and plenty of sudsy
water.
Bird droppings : Remove from paintwork as soon as possible. Otherwise the finish may be permanently damaged.
A detergent can be used to facilitate the softening of dirt and oil.
A water-soluble grease solvent may be used in cases of sticky dirt. However, use a wash place equipped with a
drainage separator.
Dry the car with a clean chamois and remember to clean the drain holes in the doors and rocker panels.
Tar spots can be removed with kerosene or tar remover after the car has been washed.
A stiff-bristle brush and lukewarm soapy water can be used to clean the wiper blades. Frequent cleaning of the
windshield and wiper blades improves visibility considerably and also helps prolong the service life of the wiper
blades.
Wash off the dirt from the underside (wheel housings, fenders, etc).
In areas of high industrial fallout, more frequent washing is recommended.
After cleaning the engine, the spark plug wells should be inspected for water and blown dry if necessary.
NOTE
When washing the car, remember to remove dirt from the drain holes in the doors and sills.
CAUTION
During high pressure washing, the spray mouthpiece must never be closer to the vehicle than 13" (30 cm). Do not
spray into the locks.

Volvo recommends Castrol oil products.
Depending on your driving habits, premium or synthetic oils may provide superior fuel economy and engine
protection. Consult your Volvo retailer for recommendations on premium or synthetic oils.
Oil additives must not be used.
Synthetic oil is not used when the oil is changed at the normal maintenance services. This oil is only used at customer
request, at additional charge. Please consult your Volvo retailer.
Oil viscosity (stable ambient temperatures)
Operation in hot climates
When temperatures exceed 104° F (40° C) in your area, Volvo recommends, for the protection of your engine, that you
use a heavier weight oil, such as such as SAE 5W -40 or 0W -40. See the viscosity chart.
Operation in temperate climates
Incorrect viscosity oil can shorten engine life. Under normal use when temperatures do not exceed 104° F (40° C),
SAE 5W -30 will provide good fuel economy and engine protection. See the viscosity chart.
Extreme engine operation
Synthetic oils meeting SAE 0W -30 or 0W -40 and 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, and for
prolonged driving in mountainous areas.
