2008 VOLVO V70 service

Passenger compartment filter
Replace the cabin air filter with a new one at the recommended intervals. Please refer to your Warranty and Service
Records Information booklet, or consult a trained and qualified Volvo service technician for these intervals. The filter
should be replaced more often when driving under dirty and dusty conditions. The filter cannot be cleaned and
therefore should always be replaced with a new one.
NOTE
There are different types of cabin air filters. Ensure that the correct type is installed.
Interior Air Quality System (IAQS)
A multifilter helps reduce gases and particles in the incoming air, thereby reducing the levels of odors and
contaminants entering the vehicle. The air quality sensor detects increased levels of contaminants in the outside air.
When the air quality sensor detects contaminated outside air, the air intake closes and the air inside the passenger
compartment is recirculated, i.e. no outside air enters the vehicle. The filter also cleans recirculated passenger
compartment air.
NOTE
Contact your Volvo retailer for IAQS air filter replacement intervals.

A pulsating sound will be audible when the system is actively operating and is normal.
Traction control (TC)
This function is designed to help reduce wheel spin by transferring power from a drive wheel that begins to lose
traction to the wheel on the opposite side of the vehicle (on the same axle).
TC is most active at low speeds.
This is one of DSTC's permanent functions and cannot be switched off.
Active Yaw Control (AYC)
This function helps maintain directional stability, for example when cornering, by braking one or more of the wheels if
the vehicle shows a tendency to skid or slide laterally.
This is one of DSTC's permanent functions and cannot be switched off.
Spin control (SC)
The spin control function is designed to help prevent the drive wheels from spinning while the vehicle is accelerating.
Under certain circumstances, such as when driving with snow chains, or driving in deep snow or loose sand, it may be
advisable to temporarily switch off this function for maximum tractive force.
WARNING
The car's handling and stability characteristics will be altered if the spin control function has been disabled.
Operation
Temporarily switching off Spin control
1. Turn the thumbwheel
until the DSTC menu is shown.
2. Hold down the RESET button
to toggle between DSTC SPIN CONTROL ON or OFF .

Front park assist
The distance monitored in front of the vehicle is approximately 2.5 ft (0.8 m). The audible signal comes from the audio
system's front speakers.
It may not be possible to combine auxiliary headlights and front park assist since these lights could trigger the system's
sensors.
Faults in the system
If the information symbol illuminates and Park Assist syst Service required is shown on the information display, this
indicates that the system is not functioning properly and has been disengaged. Consult a trained and qualified Volvo
service technician.
CAUTION
In certain circumstances, the park assist system may give unexpected warning signals that can be caused by external
sound sources that use the same ultrasound frequencies as the system. This may include such things as the horns of
other vehicles, wet tires on asphalt, pneumatic brakes, motorcycle exhaust pipes, etc. This does not indicate a fault in
the system.

BLIS camera
Indicator light
BLIS symbol
The Blind Spot Information System (BLIS) is an information system that indicates the presence of another vehicle
moving in the same direction as your vehicle in the sideview mirror's "blind area."
CAUTION
The BLIS system should only be repaired by a trained and qualified Volvo service technician.
WARNING
BLIS is an information system, NOT a warning or safety system.
BLIS does not eliminate the need for you to visually confirm the conditions around you, and the need for you to
turn your head and shoulders to make sure that you can safely change lanes.
As the driver, you have full responsibility for changing lanes in a safe manner.
The system is based on digital camera technology. The cameras are located beneath the side-view mirrors.
When one (or both) of the cameras have detected a vehicle in the blind area (up to approximately 10 ft. (3 meters)
from the side of your vehicle, and up to approximately 31 ft. (9.5 meters) behind the side-view mirror), see the
illustration, the indicator light in the door panel illuminates. The light will glow continuously to alert the driver of the
vehicle in the blind area.
NOTE
The door panel indicator light illuminates on the side of the vehicle where the system has detected another vehicle. If
your vehicle is passed on both sides at the same time, both lights will illuminate.
BLIS has an integrated function that alerts the driver if a fault should occur with the system. For example, if one or
both of the system's cameras are obscured, a message (see the table on page 185
) will appear in the information
display in the instrument panel. If this occurs, clean the camera lenses. If necessary, the system can be temporarily
switched off (for instructions, see page 185
).

cameras were obscured.
In both of the above mentioned conditions, a message will appear in the information display.
When driving in such conditions, the system's function will be limited or it may be temporarily switched off. See
page 185
for instructions.
When the message is no longer displayed, BLIS will return to normal function.
The BLIS cameras have the same limitation as the human eye. In other words, their "vision is impaired" by
adverse weather conditions such as heavy snowfall, dense fog, etc.

Limitations
In certain situations, the BLIS indicator light(s) may illuminate even when there are no other vehicles in the area
monitored by the system.
NOTE
If the BLIS indicator lights illuminate occasionally even when there are no other vehicles in the blind area, this does
not indicate a fault in the system. In the event of a fault, Blind spot syst. service required will be displayed.
The following are several examples of situations in which the BLIS indicator light(s) may illuminate even when there
are no other vehicles in the area monitored by the system.
Cleaning the BLIS camera lenses
In order to function optimally, the BLIS camera lenses must be kept clean. They can be wiped clean with a soft cloth
or wet sponge.
CAUTION
Clean the lenses carefully to avoid scratching.
The lenses are electrically heated to help melt ice or snow. If necessary, gently brush away snow from the lenses.

Water or mud can make the brake linings slippery, resulting in delayed braking effect.
CAUTION
Engine damage will occur if water is drawn into the air cleaner.
If the vehicle is driven through water deeper than 9 in (25 cm), water may enter the differential and the
transmission. This reduces the oil's lubricating capacity and may shorten the service life of these components.
Do not allow the vehicle to stand in water up to the door sills longer than absolutely necessary. This could result
in electrical malfunctions.
If the engine has been stopped while the vehicle is in water, do not attempt to restart it. Have the vehicle towed
out of the water.
Engine and cooling system
Under special conditions, for example when driving in hilly terrain, extreme heat or with heavy loads, there is a risk
that the engine and cooling system will overheat. Proceed as follows to avoid overheating the engine.
Maintain a low speed when driving with a trailer up long, steep hills.
Do not turn the engine off immediately when stopping after a hard drive.
WARNING
The cooling fan may start or continue to operate (for up to 6 minutes) after the engine has been switched off.
Remove any auxiliary lights from in front of the grille when driving in hot weather conditions.
Do not exceed engine speeds of 4500 rpm if driving with a trailer in hilly terrain. The oil temperature could become
too high.
Conserving electrical current
Keep the following in mind to help minimize battery drain:
When the engine is not running, avoid using ignition mode II . Many electrical systems (the audio system, the
optional navigation system, power windows, etc) will function in ignition modes 0 and I . These modes reduce drain on
the battery.
Please keep in mind that using systems, accessories, etc., that consume a great deal of current when the engine is not
running could result in the battery being completely drained.
The optional 12 volt socket in the cargo area provides electrical current even with the ignition switched off, which
drains the battery.

Driving recommendations
Before a long distance trip
It is always worthwhile to have your vehicle checked by a trained and qualified Volvo service technician before
driving long distances. Your retailer will also be able to supply you with bulbs, fuses, spark plugs and wiper blades for
your use in the event that problems occur.
As a minimum, the following items should be checked before any long trip:
Check that engine runs smoothly and that fuel consumption is normal.
Check for fuel, oil, and fluid leakage
Have the transmission oil level checked.
ProCarManuals.com

Check condition of drive belts.
Check state of the battery's charge.
Examine tires carefully (the spare tire as well), and replace those that are worn. Check tire pressures.
The brakes, front wheel alignment, and steering gear should be checked by a trained and qualified Volvo service
technician only.
Check all lights, including high beams.
Reflective warning triangles are legally required in some states/provinces.
Have a word with a trained and qualified Volvo service technician if you intend to drive in countries where it may
be difficult to obtain the correct fuel.
Consider your destination. If you will be driving through an area where snow or ice are likely to occur, consider
snow tires.
Cold weather precautions
If you wish to check your vehicle before the approach of cold weather, the following advice is worth noting:
Make sure that the engine coolant contains 50 percent antifreeze. Any other mixture will reduce freeze protection.
This gives protection against freezing down to - 31°F (-35°C). The use of "recycled" antifreeze is not approved by
Volvo. Different types of antifreeze must not be mixed.
Volvo recommends using only genuine Volvo antifreeze in your vehicle's radiator.
Try to keep the fuel tank well filled - this helps prevent the formation of condensation in the tank. In addition, in
extremely cold weather conditions it is worthwhile to add fuel line de -icer before refueling.
The viscosity of the engine oil is important. Oil with low viscosity (thinner oil) improves cold-weather starting as
well as decreasing fuel consumption while the engine is warming up. For winter use, 5W -30 oil, particularly the
synthetic type, is recommended. Be sure to use good quality oil but do not use cold-weather oil for hard driving or in
warm weather. See page 276
for more information on engine oil.
NOTE
Synthetic oil is not used when the oil is changed at the normal maintenance intervals except at owner request and at
additional charge.
The load placed on the battery is greater during the winter since the windshield wipers, lighting, etc. are used more
often. Moreover, the capacity of the battery decreases as the temperature drops. In very cold weather, a poorly charged
battery can freeze and be damaged. It is therefore advisable to check the state of charge more frequently and spray an
anti-rust oil on the battery posts.
Volvo recommends the use of snow tires on all four wheels for winter driving. See the information on page 259.
To prevent the washer fluid reservoir from freezing, add washer solvents containing antifreeze. This is important
since dirt is often splashed on the windshield during winter driving, requiring the frequent use of the washers and
wipers. Volvo Washer Solvent should be diluted as follows: Down to 14° F (-10° C): 1 part washer solvent and 4 parts
water Down to 5° F (-15° C):
195 05 During your trip
Driving recommendations
1 part washer solvent and 3 parts water Down to 0° F (-18° C): 1 part washer solvent and 2 parts water Down to -18°
F (-28° C): 1 part washer solvent and 1 part water.
Use Volvo Teflon Lock Spray in the locks.
Avoid using de -icing sprays as they can cause damage to the locks.

Fuel requirements
Deposit control gasoline (detergent additives)
Volvo recommends the use of detergent gasoline to control engine deposits. Detergent gasoline is effective in keeping
injectors and intake valves clean. Consistent use of deposit control gasolines will help ensure good drivability and fuel
economy. If you are not sure whether the gasoline contains deposit control additives, check with the service station
operator.
NOTE
Volvo does not recommend the use of external fuel injector cleaning systems.
Unleaded fuel
Each Volvo has a three-way catalytic converter and must use only unleaded gasoline. U.S. and Canadian regulations
require that pumps delivering unleaded gasoline be labelled "UNLEADED". Only these pumps have nozzles which fit
your vehicle's filler inlet. It is unlawful to dispense leaded fuel into a vehicle labelled "unleaded gasoline only".
Leaded gasoline damages the three-way catalytic converter and the heated oxygen sensor system. Repeated use of
leaded gasoline will lessen the effectiveness of the emission control system and could result in loss of emission
warranty coverage. State and local vehicle inspection programs will make detection of misfueling easier, possibly
resulting in emission test failure for misfueled vehicles.
NOTE
Some U.S. and Canadian gasolines contain an octane enhancing additive called methyl-cyclopentadienyl manganese
tricarbonyl (MMT). If such fuels are used, your Emission Control System performance may be affected, and the
Check Engine Light (malfunction indicator light) located on your instrument panel may light. If this occurs, please
return your vehicle to a trained and qualified Volvo service technician for service.
Gasoline containing alcohol and ethers, "Oxygenated fuels"
Some fuel suppliers sell gasoline containing "oxygenates" which are usually alcohols or ethers. In some areas, state or
local laws require that the service pump be marked indicating use of alcohols or ethers. However, there are areas in
which the pumps are unmarked. If you are not sure whether there is alcohol or ethers in the gasoline you buy, check
with the service station operator. To meet seasonal air quality standards, some areas require the use of "oxygenated"
fuel.
Volvo allows the use of the following "oxygenated" fuels; however, the octane ratings listed on page 197
must still be
met.
Alcohol - Ethanol
Fuels containing up to 10% ethanol by volume may be used. Ethanol may also be referred to as Ethyl alcohol, or
"Gasohol".
Ethers - MTBE: Fuels containing up to 15% MTBE may be used.
Methanol
Do not use gasolines containing methanol (methyl alcohol, wood alcohol). This practice can result in vehicle
performance deterioration and can damage critical parts in the fuel system. Such damage may not be covered under the
New Vehicle Limited Warranty.
