1998 VOLVO C70 check engine

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.

The ABS system in your car performs a self -diagnostic test when the vehicle first reaches the speed of approximately
12 mph (20 km/h). The brake pedal will pulsate several times and a sound may be audible from the ABS control
module. This is normal.
Fuel tank cover
The fuel tank cover is locked and must be popped open using the control on the driver's door.
The pages in this section provide detailed descriptions of the vehicle's instruments and controls. Note that vehicles may
be equipped differently, depending on special legal requirements.

1 Fuel gauge
The fuel tank holds approximately 18.4 US gals. (70 liters). When the warning light comes on there is approximately
1.8 US gals. (8 liters) of fuel remaining. See "Refueling" for further information.

2 Temperature gauge
Do not drive the car with the pointer in the red range. The pointer should be approximately midway on the gauge
face when driving. If the pointer approaches the red range repeatedly, check coolant level. See page 130

A new car should be broken -in

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
