wheel VOLVO C70 2008 Workshop Manual

Temporarily repairing a flat tire is done in two stages:
Stage 1: The hole is sealed by pumping sealing compound into the tire. The car is then driven a short distance to
distribute the sealing compound in the tire.
NOTE
Do not remove any foreign objects (nails, etc.) from the tire before using the sealing system.
NOTE
Stage 2: The tire's inflation pressure is checked and adjusted if necessary.
WARNING
Never leave the tire sealing system unattended when it is operating.
Keep the tire sealing system away from children.
Be sure the vehicle is parked safely off the road and away from moving traffic.
Apply the parking brake.
Stage 1: Sealing the hole
1. Open the cover on the tire sealing kit.
2. Peel off the speed limit sticker and affix it to the steering wheel hub where it will be clearly visible to the driver.
3. Ensure that the on/off switch is in position 0 (the 0 side of the switch should be pressed down).
4. Put on the gloves included in the tire sealing system.
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 Volvo retailer.
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.

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 workshop or
Volvo retailer.
Stage 2: Checking inflation pressure
1. Connect the tire sealing system as described in stage 1.
2. Refer to the tables on pages 172 and 173
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
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.
the container's expiration date has passed (see the date on decal).
NOTE
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.

Tire Pressure Monitoring System (TPMS)
Introduction
The tire pressure monitoring system uses sensors mounted in the tire valves to check inflation pressure levels. When
ProCarManuals.com

the vehicle is moving at a speed of approximately 20 mph (30 km/h) or faster, these sensors transmit inflation pressure
data to a receiver located in the vehicle.
NOTE
USA - FCC ID: KR5S122780002
This device complies with part 15 of the FCC rules. Operation is subject to the following conditions: (1) This device
may not cause harmful interference, and (2) this device must accept any interference received, including interference
that may cause undesired operation.
When low inflation pressure is detected, TPMS will light up the tire pressure warning light (
) (also referred to as a
telltale) in the instrument panel, and will display a message in the text window. The wording of this message is
determined by the degree of inflation pressure loss.
NOTE
If a fault occurs in TPMS, the tire pressure warning light will flash for approximately 1 minute and TIRE PRESS
SYST SERVICE REQUIRED will be displayed.
Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure
recommended by the vehicle manufacturer on the vehicle placard or tire inflation pressure label. (If your vehicle has
tires of a different size than the size indicated on the vehicle placard or tire inflation pressure label, you should
determine the proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire pressure monitoring system (TPMS) that
illuminates a low tire pressure telltale when one or more of your tires is significantly under-inflated. Accordingly,
when the low tire pressure telltale illuminates, you should stop and check your tires as soon as possible, and inflate
them to the proper pressure. Driving on a significantly under-inflated tire causes the tire to overheat and can lead to
tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle's handling and
stopping ability.
Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driver's responsibility to
maintain correct tire pressure, even if under-inflation has not reached the level to trigger illumination of the TPMS low
tire pressure telltale.
Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the system is not operating
properly. The TPMS malfunction indicator is combined with the low tire pressure telltale. When the system detects a
malfunction, the telltale will flash for approximately one minute and then remain continuously illuminated. This
sequence will continue upon subsequent vehicle start-ups as long as the malfunction exists. When the malfunction
indicator is illuminated, the system may not be able to detect or signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of reasons, including the installation of replacement or alternate tires or wheels
on the vehicle that prevent the TPMS from functioning properly. Always check the TPMS malfunction telltale after
replacing one or more tires or wheels on your vehicle to ensure that the replacement or alternate tires and wheels allow
the TPMS to continue to function properly.

Tire Pressure Monitoring System (TPMS)
NOTE
ProCarManuals.com

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 172 or consult your Volvo retailer.
The tire pressure warning light will not identify which tire is underinflated. 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 172
.
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.

Washing
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 when salt
has been used on the roads.
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.
ProCarManuals.com

NOTE
When washing the car, remember to remove dirt from the drain holes in the doors and sills.
Exterior components
Volvo recommends the use of special cleaning products, available at your Volvo retailer, for cleaning colored plastic,
rubber, or ornamental components such as chromed strips on the exterior of your vehicle. The instructions for using
these products should be followed carefully. Solvents or stain removers should not be used.
CAUTION
Avoid waxing or polishing plastic or rubber components
Polishing chromed strips can wear away or damage the surface
Polishes containing abrasive substances should not be used
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.
Dirt, snow, etc., on the headlights can reduce lighting capacity considerably. Clean the headlights regularly, for
example when refueling.
When washing or steam cleaning the engine, avoid spraying water or steam directly on the electrical components
or toward the rear side of the engine.
Chromed wheels : Clean chrome-plated wheels using the same detergents used for the body of the vehicle.
Aggressive wheel-cleaning agents can permanently stain chrome-plated wheels.
197 08 Car care
Washing and cleaning the vehicle
Automatic washing - simple and quick
We do NOT recommend washing your car in an automatic wash during the first six months (because the paint will not
have hardened sufficiently).
An automatic wash is a simple and quick way to clean your car, but it is worth remembering that it may not be as
thorough as when you yourself go over the car with sponge and water.
Keeping the underbody clean is most important, especially in the winter. Some automatic washers do not have
facilities for washing the underbody.
CAUTION
Before driving into an automatic car wash, turn off the optional rain sensor to avoid damaging the windshield
wipers.
Make sure that side view mirrors, auxiliary lamps, etc, are secure, and that any antenna(s) are retracted or removed.
Otherwise there is risk of the machine dislodging them.
WARNING
When the car is driven immediately after being washed, apply the brakes several times in order to remove any
ProCarManuals.com

The brake fluid should always be between the MIN and MAX marks on the side 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 your Volvo retailer. Always entrust brake fluid changing to a trained and
qualified Volvo service technician.
Power steering fluid
The fluid level is checked at each service interval.
Fluid type : Volvo power steering fluid or equivalent.
Replace : No fluid change required.
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.
