CAUTION
l Engine damage will occur if water is drawn into the air cleaner.
l 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 sh\
orten the service life of these
components.
l Do not allow the vehicle to stand in water up to the door sills longer t\
han absolutely necessary. This
could result in electrical malfunctions.
l If the engine has been stopped while the car is in water, do not attempt\
to restart the engine. Have the
car towed out of the water.
Cold weather precautions
If you wish to check your vehicle before the approach of cold weather, t\
he following advice is worth
noting:
l Make sure that the engine coolant contains 50 percent antifreeze. Any ot\
her mixture will reduce freeze
protection. This gives protection against freezing down to - 31°F (-\
35°C). See section "Coolant". The use
of "recycled" antifreeze is not approved by Volvo. Different types of an\
tifreeze must not be mixed.
l Volvo recommends using only genuine Volvo antifreeze in your vehicle's r\
adiator. Your Volvo retailer
stocks plenty of Volvo engine coolant to help protect your vehicle durin\
g cold weather.
l Try to keep the fuel tank well filled - this prevents the formation of c\
ondensation in the tank. In
addition, in extremely cold weather conditions it is worthwhile to add f\
uel line de-icer before refueling.
l The viscosity of the engine oil is important. Oil with low viscosity (t\
hinner oil) improves cold-weather
starting as well as decreasing fuel consumption while the engine is warm\
ing up. For winter use, 5W-30
oil, particularly the synthetic type
1, 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 239 for more information.
l The load placed on the battery is greater during the winter since the wi\
ndshield 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 there\
fore advisable to check the state
of
1Synthetic oil is not used when the oil is changed at the normal maintena\
nce intervals except at owner request and
at additional charge. Please consult your Volvo retailer.

charge more frequently and spray an antirust oil on the battery posts.
l Volvo recommends the use of snow tires on all four wheels for winter dri\
ving - see the chapter "Wheels
and tires."

l To prevent the washer fluid reservoir from freezing, add washer solvents\
containing antifreeze (see
page 193 for the location of the washer fluid reservoir). This is important sin\
ce 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): 1 part washer solvent and 3 parts water D\
own 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.
l Use Volvo Teflon Lock Spray in the locks.
NOTE
Avoid using de-icing sprays as they can cause damage to the
locks.
Conserving electrical current
Keep the following in mind to help minimize battery drain:
l When the engine is not running, avoid turning the ignition key to positi\
on II. Many electrical systems
(the audio system, the optional navigation system, power windows, etc)\
will function with the ignition
key in position I. This position reduces drain on the battery.
l 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 drain\
ed.
l The optional 12 volt socket in the cargo area provides electrical curren\
t even with the ignition switched
off, which drains the battery.
NOTE
l If the ignition is switched on, a warning message will be displayed in t\
he text window in the
instrument panel when the battery charge is low.
l An energy conserving function designed into the vehicle's electrical sys\
tem will switch off certain
functions or reduce the load on the battery by, e.g., reducing the audio\
system's volume.
Before a long distance trip
It is always worthwhile to have your vehicle checked at a Volvo retailer\
before driving long distances.
Your retailer will also be able to supply you with bulbs, fuses, spark p\
lugs 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\
:
l Check that engine runs smoothly and that fuel consumption is normal.
l Check for fuel, oil, and fluid leakage
l Have the transmission oil level checked1.

l Check condition of drive belts.
l Check state of the battery's charge.
l Examine tires carefully (the spare tire as well), and replace those th\
at are worn. Check tire pressures.
l The brakes, front wheel alignment, and steering gear should be checked b\
y your Volvo retailer only.
l Check all lights, including high beams.
l Reflective warning triangles are legally required in some states/provinc\
es.
l Have a word with your Volvo retailer if you intend to drive in countries\
where it may be difficult to
obtain the correct fuel.
l Consider your destination. If you will be driving through an area where \
snow or ice are likely to occur,
consider snow tires.
1 To prevent injury from contact with hot surfaces, do not inspect your v\
ehicle's transmission fluid yourself. Have
your vehicle's transmission fluid level inspected by a qualified Volvo s\
ervice technician.

Fuel requirements
Octane rating
Volvo engines are designed to achieve rated horsepower, torque, and fuel\
economy performance using
premium 91 octane fuel.
Volvo recommends premium for best performance, but using 87 octane or ab\
ove will not affect engine
reliability.
file:///K|/delme/2007_C70/07c70_06.htm (6 of 18)12/22/2006 9:15:48 PM

2007 Volvo C70
In demanding driving conditions, such as operating the vehicle in hot we\
ather, towing a trailer, or driving
for extended periods at higher altitudes than normal, it may be advisabl\
e to switch to higher octane fuel
(91 or higher) or to change gasoline brands to fully utilize your engi\
ne's capacity, and for the smoothest
possible operation.
NOTE
When switching to higher octane fuel or changing gasoline brands, it may\
be necessary to fill the tank
more than once before a difference in engine operation is noticeable.
Deposit control gasoline (detergent additives)
Volvo recommends the use of detergent gasoline to control engine deposit\
s. Detergent gasoline is
effective in keeping injectors and intake valves clean. Consistent use o\
f deposit control gasolines will help
ensure good drivability and fuel economy. If you are not sure whether th\
e gasoline contains deposit
control additives, check with the service station operator.
NOTE
Volvo does not recommend the use of store-bought fuel injector cleaning \
additives.
Unleaded fuel
Each Volvo has a three-way catalytic converter and must use only unleade\
d 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 t\
hree-way catalytic converter and
the heated oxygen sensor system. Repeated use of leaded gasoline will le\
ssen the effectiveness of the
126 06 Starting and driving
Fuel requirements
emission control system and could result in loss of emission warranty co\
verage. State and local vehicle
inspection programs will make detection of misfueling easier, possibly r\
esulting in emission test failure
for misfueled vehicles.
NOTE
Some U.S. and Canadian gasolines contain an octane enhancing additive ca\
lled methyl-
cyclopentadienyl manganese tricarbonyl (MMT). If such fuels are used, \
your Emission Control System
performance may be affected, and the Check Engine Light (malfunction in\
dicator lamp) located on your
instrument panel may light. If this occurs, please return your vehicle t\
o an authorized Volvo retailer for
maintenance.
Gasoline containing alcohol and ethers
Some fuel suppliers sell gasoline containing "oxygenates" which are usua\
lly alcohols or ethers. In some
areas, state or local laws require that the service pump be marked indic\
ating 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 this page must\
still be met. Alcohol - Ethanol:
Fuels containing up to 10% ethanol by volume may be used. Ethanol may al\
so be referred to as Ethyl
alcohol, or "Gasohol". Ethers - MTBE: Fuels containing up to 15% MTBE ma\
y be used.
Fuel Formulations
Do not use gasoline that contains lead as a knock inhibitor, and do not \
use lead additives. Besides
damaging the exhaust emission control systems on your vehicle, lead has \
been strongly linked to certain
forms of cancer. Many fuels contain benzene as a solvent. Unburned benze\
ne has been strongly linked to
certain forms of cancer. If you live in an area where you must fill your\
own gas tank, take precautions.
These may include:
l standing upwind away from the filler nozzle while refueling
l refueling only at gas stations with vapor recovery systems that fully se\
al the mouth of the filler neck
during refueling

pump's ability to supply the engine with an adequate supply of fuel.
Therefore, it is advisable to refuel as soon as possible when the needle\
nears the red zone, or when the
fuel warning light comes on.
1Models with All Wheel Drive have a tank volume of 15 US gallons (57 lit\
ers). Models with engine code 39 have
a fuel tank capacity of 14 US gallons (53 liters). This code is the 6t\
h and 7th digits from the left in your vehicle's
VIN number. See
page 235 for the location of the VIN plate.
CAUTION
l Do not refuel with the engine running1. Turn the ignition off or to position I. If the ignition is on, an
incorrect reading could occur in the fuel gauge
l After refueling, close the fuel filler cap by turning it clockwise until\
it clicks into place.
l Avoid overfilling the fuel tank. Do not press the handle on the filler n\
ozzle more than one extra time.
Too much fuel in the tank in hot weather conditions can cause the fuel t\
o overflow. Overfilling could
also cause damage to the emission control systems.
l Avoid spilling gasoline during refueling. In addition to causing damage \
to the environment, gasolines
containing alcohol can cause damage to painted surfaces, which may not b\
e covered under the New
Vehicle Limited Warranty.
l 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 f\
uel system. Such damage may
not be covered under the New Vehicle Limited Warranty.
1If the fuel filler cap is not closed tightly or if the engine is running\
when the vehicle is refueled, the Check Engine
Light (malfunction indicator lamp) may indicate a fault. However, your\
vehicle's performance will not be affected.
Use only Volvo original or approved fuel filler caps.
