1998 VOLVO C70 brake sensor

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.

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.
pg. 16 Instruments
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
.
3 Speedometer
4 Clock, ambient temperature sensor, trip computer (certain models)
5 Odometer
6 Trip odometer
Used for measuring shorter distances. The last digit indicates 1/10 mile/kilometer.
7 Trip odometer reset button
8 Tachometer
Reads thousands of engine rpm. The engine should not be operated in red range. The highest permitted constant
engine speed is 6,200 rpm.
