check engine VOLVO C70 2003 Owners Manual

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 as far back as 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 a 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, indicating 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 in your Warranty and Service Records Information booklet.
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

A self -diagnostic system incorporated in the sensor monitors the SRS. This system does not, however, monitor the
SIPS airbags. If a fault is detected, the "SRS" warning light will illuminate. The light is included in the
warning/indicator light cluster in the instrument panel. Normally, the SRS warning lamp should light up when the
ignition is switched on and should go out after 5 seconds or when the engine is started. Check that this light is
functioning properly every time the car is started.
The following items are monitored by the self -diagnostic system:
Sensor unit
Cable harness
Gas generator igniters
WARNING!
Never drive an SRS equipped car with your hands on the steering wheel pad/airbag housing.
No objects, accessory equipment or stickers may be placed on, attached to or installed near the SRS cover in the
center of the steering wheel, the SRS cover above the glove compartment or the area affected by airbag deployment.
If the SRS warning light stays on after the engine has started or if it comes on while you are driving, drive the car
to the nearest authorized Volvo retailer for inspection as soon as possible.
There is no maintenance to perform on the SRS yourself. The month and year shown on the decal on the door pillar
indicate when you should contact your Volvo retailer for specific servicing or replacement of airbags and seat belt
tensioners. This service must be performed by an authorized Volvo retailer.
Should you have any questions about the SRS system, please contact
your authorized Volvo retailer or Volvo Customer Support:

The warning lights described on pages 18 and 19 should never stay on when driving
When the ignition key is turned on and before the engine starts, all of the warning lights should go on to test the
function of the bulbs. Should a light not go off after the engine has started, the system indicated should be inspected.
However, the parking brake reminder light will not go off until the parking brake has been fully released.
Malfunction indicator lamp
On-Board Diagnostic II (OBDII): As you drive, a computer called "OBDII" monitors your car's engine, transmission,
electrical and emission systems. The CHECK ENGINE light will light up if the computer senses a condition that
potentially may need correcting. When this happens, please have your car checked by a Volvo retailer as soon as
possible.
A CHECK ENGINE light may have many causes. Sometimes, you may not notice a change in your car's behavior.
Even so, an uncorrected condition could hurt fuel economy, emission cleanliness, and driveability. Extended driving
without correcting the cause could even damage other components in your car.
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. However, your vehicle's performance will not be affected. Use only Volvo
original or approved fuel filler caps.
Canadian models are equipped with this warning light:
Oil pressure warning light
If the light comes on while driving, stop the car and then stop the engine immediately and check the engine oil
level . See page 116.
If the light stays on after restart, have the car towed to the nearest authorized Volvo retailer. After
hard driving, the light may come on occasionally when the engine is idling. This is normal, provided it goes off when
the engine speed is increased.
Roll Over Protection System (ROPS)
If the warning lamp remains on after the engine has started or comes on while you are driving, the ROPS self -
diagnostic system has detected a fault. The car should be driven to an authorized Volvo retailer as soon as possible for
inspection.
Please refer to page 10
for more information on the ROPS system.
Brake failure warning light
If the light comes on while driving or braking, stop immediately, open the hood and check the brake fluid level

STC disengaged
The indicator light (
) in the instrument panel will be ON when you have switched the Stability and Traction Control
system (STC) OFF using the button on the dashboard (see page 23
). The light will also come on if there is a fault in the
STC system or to indicate that the brakes have overheated. The light will go out when the brake temperature returns to
normal.
The
symbol will flash when STC is actively regulating power to the drive wheels. Normal power may be reduced at
this time. This is normal as power is momentarily reduced to help keep the drive wheels from losing traction and
spinning.
Anti-lock Brake system (ABS)
If the warning lamp lights up there is a malfunction of the ABS system (the standard braking system will however
function). The vehicle should be driven to a Volvo retailer for inspection.
See page 74
for additional information.
Canadian models are equipped with this warning light:

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 116-117.
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.

Posted speed limits should not be exceeded.
Deposit control (detergent) gasoline
Volvo recommends the use of detergent gasoline to control engine deposits. Detergent gasoline is effective 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 labelled "UNLEADED". Only these pumps have nozzles which fit
your car's filler inlet. It is unlawful to dispense leaded fuel into a vehicle labelled "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 methly-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.
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).

Fuel Formulations
ProCarManuals.com

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 car, lead has been strongly linked to certain forms of cancer.
Many fuels contain benzene as a solvent. Unburned benzene 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:
standing upwind away from the filler nozzle while refueling
refueling only at gas stations with vapor recovery systems that fully seal the mouth of the filler neck during refueling
wear neoprene gloves while handling a fuel filler nozzle.
Use of Additives
With the exception of gas line antifreeze during winter months, do not add solvents, thickeners, or other store -bought
additives to your car's fuel, cooling, or lubricating systems. Overuse may damage your engine, and some of these
additives contain organically volatile chemicals. Do not needlessly expose yourself to these chemicals.
Carbon Monoxide - Important Warning
Carbon monoxide is a poisonous, colorless, and odorless gas. It is present in all exhaust gases. If you ever smell
exhaust fumes inside the vehicle, make sure the passenger compartment is ventilated, and immediately return the
vehicle to your retailer for correction.
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 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 also be referred to as Ethyl alcohol, or "Gasohol".
Ethers — MTBE
Fuels containing up to 15% MTBE may be used.
