engine VOLVO C70 1999 Owners Manual

This manual deals with the operation and care of your Volvo.
Welcome to the world-wide family of Volvo owners. We trust that you will enjoy many years of safe driving in your
Volvo, an automobile designed with your safety and comfort in mind. To help ensure your satisfaction with this
vehicle, we encourage you to familiarize yourself with the equipment descriptions, operating instructions and
maintenance requirements/recommendations in this manual. We also urge you and your passengers to wear seat belts
at all times in this (or any other) automobile. And, of course, please do not operate a vehicle if you may be affected by
alcohol, medication or any impairment that could hinder your ability to drive.
Your Volvo is designed to meet all applicable safety and emission standards, as evidenced by the certification labels
attached to the driver's door opening and on the left wheel housing in the engine compartment.
Volvo and the environment
Volvo is committed to the well being of our customers. As a natural part of this commitment, we care about the
environment in which we all live. Caring for the environment means an everyday involvement in reducing our
environmental impact.
Volvo's environmental activities are based on a holistic view, which means we consider the overall environmental
impact of a product throughout its complete life cycle. In this context, design, production, product use, and recycling
ProCarManuals.com

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.

Refrain from utilizing your car's full driving potential during the first 1,200 miles (2,000 km) including the "kick -
down" function (automatic transmission).
NOTE - ENGINE OIL:
Although some oil consumption occurs during normal engine operation, more oil is consumed when the engine is new
as the internal parts generate higher friction while wearing-in to each other. From the time the engine is new until
the first service is performed, the oil consumption could be higher than normal. For this reason, it is especially
important to check the oil every time you refuel your car during this period. See page 114
.
In general, the rate of oil consumption depends on such factors as: engine temperature, length of trip, driving
conditions, oil viscosity and quality, engine speed and acceleration/deceleration.
Checking your engine oil level each time the car is refueled is one of the most important items you can perform to
help keep your car in good running order.

5th gear/overdrive 80 mph (130 km/h)95 mph (150 km/h)
Posted speed limits should not be exceeded.
Deposit control gasoline (detergent additives)
Volvo recommends the use of gasoline containing deposit control additives. These additives have shown to be efficient
in keeping injectors and intake valves clean. Consistent use of deposit control gasolines will help ensure good
driveability and fuel economy. If you are not sure whether the gasoline contains deposit control additives, check with
the service station operator.
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 labeled "UNLEADED". Only these pumps have nozzles which fit
your car's filler inlet. It is unlawful to dispense leaded fuel into a vehicle labeled "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 Malfunction Indicator Lamp located on your instrument panel may light. If this occurs, please return your
vehicle to an authorized Volvo retailer for service.
pg. 57 Fuel requirements, Refueling
Octane Rating

Volvo engines are designed for optimum performance on unleaded premium gasoline with an octane rating. AKI of 91,
or above. AKI (ANTI KNOCK INDEX) is an average of the Research Octane Number, RON, and the Motor Octane
Number, MON, (RON + MON/ 2).
The minimum octane requirement is AKI 87 (RON 91).
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 alcohol 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 restrictions, some states require the use of "oxygenated" fuel in certain areas.
Volvo allows the use of the following "oxygenated fuels; however, the octane ratings listed on this page must still be
met.
Alcohol — Ethanol
ProCarManuals.com

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 tank is designed to hold approximately 17.9 US gal. (68 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 "Reid 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.
Fuel tank cover
The fuel tank cover (on the right rear fender) is locked and must be popped open using the control on the driver's door.
Open fuel filler cap slowly during hot weather conditions.
CAUTION:
Do not refuel with the engine running. Turn the ignition off or to position I. If the ignition is on, an incorrect
reading could occur in the fuel gauge.
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.
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.
* 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. However, your vehicle's performance will not be affected. Use only Volvo
original or approved fuel filler caps.
