1998 VOLVO C70 fuel pressure

are all important considerations.
In production, Volvo has partly or completely phased out several chemicals including freons, lead chromates,
naphtanates, asbestos, mercury and cadmium; and reduced the amount of chemicals used in our plants 50% since 1991.
In use, Volvo was the first in the world to introduce into production a three-way catalytic converter with a Lambda
sond, now called oxygen sensor, in 1976. The current version of this highly efficient system reduces emissions of
harmful substances (CO, HC, NOx) from the exhaust pipe by approximately 95% and the search to eliminate the
remaining emissions continues. Volvo is the only automobile manufacturer to offer CFC-free retrofit kits for the air
conditioning system for all models back to the M/Y 1975 240. Advanced electronic engine controls, refined
purification systems and cleaner fuels are bringing us closer to our goal.
After Volvo cars and parts have fulfilled their use, recycling is the next critical step in completing the life cycle. The
metal content is about 75% of the total weight of the car, which makes the car among the most recycled industrial
products. In order to have efficient and well controlled recycling, many Volvo variants have printed dismantling
manuals indication the weight and material of individual components. For Volvo, all homogeneous plastic parts
weighing more than 1.7 oz. (50 grams)are marked with international symbols that indicate how the component is to be
sorted for recycling.
In addition to continuous environmental refinement of conventional gasoline-powered internal combustion engines,
Volvo is actively looking at advanced technology alternative-fuel vehicles.
When you drive a Volvo, you become our partner in the work to lessen the car's impact on the environment.
To reduce your vehicle's environmental impact, you can:
Maintain proper air pressure in your tires. Tests have shown decreased fuel economy with improperly inflated
tires
Follow the recommended maintenance schedule
Drive at a constant speed
See an authorized Volvo retailer as soon as possible for inspection if the check engine (malfunction indicator)
lamp illuminates, or stays on after the vehicle has started
Properly dispose of any vehicle related waste such as used motor oil, used batteries, brake pads, etc.
When cleaning your car, use Volvo's own car care products, all of which have systematically been adapted to
the environment.

Important
Before you operate your car for the first time, please familiarize yourself with the BREAK-IN information on
page 56. You should also be familiar with the information in the first three chapters of this manual.
Information contained in the balance of the manual is extremely useful and should be studied after operating
the vehicle for the first time.
This manual is structured so that it can be used for reference. It should thus be kept in the car for ready access.
Do not export your Volvo to another country before investigating the country's applicable safety and exhaust
emission requirements. In some cases it may be difficult or impossible to comply with these requirements.
Modifications to the emission control system(s) may render your Volvo not certifiable for legal operation in the
U.S., Canada or other countries.
All information, illustrations and specifications contained in this manual are based on the latest product information
available at the time of publication. Volvo reserves the right to make model changes at any time, or to change
specifications or design, without notice and without incurring obligation.

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.
Refueling
The fuel filler cap is located inside the fuel tank cover on the right rear fender.
NOTE: The fuel tank cover is locked and must be popped open using the control on the driver's door (see page 37).

Open fuel filler cap slowly during hot weather conditions.
When filling, hang the cap on the special bracket on the inside of the fuel tank cover.
NOTE: Turn the ignition off or to position I when refueling. If the ignition is on, an incorrect reading could occur in
the fuel gauge (low fuel level will be indicated).
After filling the tank, install the cap and turn until a "click" is heard.
The fuel tank is designed to hold approximately 18.4 US gal. (70 liters) with sufficient volume left over to
accommodate possible expansion of the fuel in hot weather. Be aware that the "usable" tank will be somewhat less than
the specified maximum. When the fuel level is low, such factors as ambient temperature, the fuel's "vapor pressure"
characteristics, and terrain can affect the fuel pumps' 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.
CAUTION:
Do not refuel with the engine running. After refueling, close the fuel filler cap by turning it clockwise until it
clicks into place.
Allow for fuel expansion by not overfilling the tank. Overfilling could also cause damage to the emission control
systems.
NOTE: If the fuel filler cap is not closed tightly or if the engine is running when the car is refueled, the Malfunction
Indicator Lamp may indicate a fault. Use only Volvo original or approved fuel filler caps.
CAUTION: Avoid spilling gasoline during refueling. Gasolines containing alcohol can cause damage to painted
surfaces, which may not be covered under the New Vehicle Limited Warranty.
Do not use gasoline 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.

different design as this could also negatively affect overall tire road grip. Volvo recommends 195/65 R15 winter tires
on 15" steel wheels on all C70 models including those equipped with 16", 17" or 18" wheels.
Winter tires wear more quickly on dry roads in warm weather. They should be removed when the winter driving
season has ended.
Studded tires should be run-in 300-600 miles (500-1000 km) during which the car should be driven as smoothly as
possible to give the studs the opportunity to seat properly in the tires. The car tires should have the same rotational
direction throughout their entire lifetime. In other words, if you wish to rotate the wheels, make sure that the same
wheels are always on the same side of the car.
NOTE: Please consult state or local regulations restricting the use of studded winter tires before installing such tires.
* Where permitted
pg. 78 Wheels and tires (cont.)
Checking and correcting tire pressure
Check the tire pressure when refueling.
The tire pressure should be corrected only when the tires are cold.
With warm tires, correct only when the pressure is too low. The tire temperature rises after driving just a few miles.
Vehicle Loading
The tires on your Volvo will perform to specifications at all normal loads when inflated as recommended on the tire
information label* located on the rear facing edge of the passenger's door. This label lists both the tire and vehicle
design limits.
Do not load your car beyond the load limits indicated.
* Please note that the tire information label indicates pressures for both comfort and fuel economy.

Uniform tire quality grading

ALL PASSENGER CAR TIRES MUST CONFORM TO FEDERAL SAFETY REQUIREMENTS IN
ADDITION TO THESE GRADES
TREADWEAR
The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions
on a specified government test course. For example, a tire graded at 150 would wear one and one half (1 1/2) times as

CAUTION: Correct tightening torque on wheel bolts must be observed. The wheel bolts should never be greased or
lubricated. The extended, chromed wheel bolts must not be used with steel rims, as they make it impossible to fit the
hub caps.
pg. 84 Spare tire
Temporary Spare (certain models)
The spare tire of your car is what is called a "Temporary Spare". It has the following designation: T115/70 R15 or
T125/90R15.
Recommended tire pressure (see decal on fuel filler flap) should be maintained irrespective of which position on the
car the Temporary Spare tire is used on.
In the event of damage to this tire a new one can be purchased from your Volvo retailer.
CAUTION: The car must not be driven with wheels of different dimensions or with a spare tire other than the one
that came with the car. The use of different size wheels can seriously damage your car's transmission.
WARNING!
Current legislation prohibits the use of the "Temporary Spare" tire other than as a temporary replacement for a
punctured tire. In other words, it must be replaced as soon as possible by a standard tire. Roadholding, etc., may be
affected with the "Temporary Spare" in use. Do not, therefore, exceed 50 mph (80 km/h).
