check engine VOLVO V4 2002 Owners Manual

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 Infromation 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

The entire process, including inflation and deflation of the airbags, takes approximately two-tenths of a second.
WARNING!
· As its name implies, SRS is designed to be a SUPPLEMENT to - not a replacement for - the three-point belt
system. For maximum protection, wear seat belts at all times. Be aware that no system can prevent all possible
injuries that may occur in an accident.
· When installing any optional equipment, make sure that the SRS system is not damaged. Do not attempt to service
any component of the SRS yourself. Attempting to do so may result in serious personal injury. If a problem arises,
take your car to the nearest authorized Volvo retailer for inspection as soon as possible.
pg. 5 Volvo SRS
A self -diagnostic system incorporated into the sensor monitors the SRS, SIPS and IC-system. 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
· SRS wiring
· InflatorsWARNING!
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.

The warning lights described on pages 22 and 23 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.
Supplemental Restraint System (SRS)
If the light comes on (or stays on after the vehicle has started), the SRS diagnostic system has detected a fault.
Drive to an authorized Volvo retailer for an inspection of the system. See the SRS section for more information.
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 114.
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.
Parking brake reminder light
This light will be on when the parking brake (hand brake) is applied. The parking brake lever is situated
between the front seats.

whichever occurs first. It is a reminder to the driver that the service interval has been exceeded. The light will
stay on for 2 minutes after start until reset by the servicing retailer.
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 73
for additional information.
Malfunction Indicator Lamp
On-Board Diagnostics 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.

Deposit control gasoline (detergent additives)
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
ProCarManuals.com

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 methly-cyclopentadienyl
manganese tricarbonyl (MMT). If such fuels are used, your Emission Control System performance may be affected,
and the Check Engine Lamp located on your instrument panel may light. If this occurs, please return your vehicle to
an authorized Volvo retailer for service.
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.
Fuel Formulations
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.
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
.
pg. 63 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).
ProCarManuals.com

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 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.
Refueling
The fuel tank is designed to hold approximately: 16 US gallons (60 liters) with sufficient volume left over to
accommodate possible expansion of the fuel in hot weather.
Fuel filler door
The fuel filler door (on the left rear fender) is unlocked along with the car's central locking system.
Open fuel filler cap slowly during hot weather.
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 *.
· 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 gasolines 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.
· Do not overfill the fuel tank. Overfilling could damage the emission control system.
* If the fuel filler cap is not closed tightly or if the engine is running when the car is refueled, the Check Engine
Lamp may indicate a fault. However, your vehicle's performance will not be affected. Use only Volvo original or
approved fuel filler caps.

pg. 64 Driving economy
Economical driving conserves natural resources
Better driving economy may be obtained by thinking ahead, avoiding rapid starts and stops and adjusting the speed of
your vehicle to immediate traffic conditions. Observe the following rules:
· Bring the engine to normal operating temperature as soon as possible by driving with a light foot on the accelerator
pedal for the first few minutes of operation. A cold engine uses more fuel and is subject to increased wear.
· Whenever possible, avoid using the car for short trips. Short trips do not allow the engine to reach normal operating
temperature.
· Drive carefully and avoid rapid acceleration and hard braking.
· Do not exceed posted speed limits.
· Avoid carrying unnecessary items (extra load) in the car.
· Maintain correct tire pressure. Check tire pressure regularly (check when tires are cold).
· Remove snow tires when threat of snow or ice has ended.
· Note that roof racks, ski racks, etc., increase air resistance and thereby fuel consumption.
· Avoid using automatic transmission kickdown feature unless necessary.
· Avoid using the air conditioning when it is not required. When engaged, the air conditioner's compressor places an
additional load on the engine. However, please note that fuel consumption is lower with the air conditioning on than it
is when driving with the air conditioning switched off and the windows down.
· Utilizing the fuel consumption modes in the Trip Computer can help you "learn" how to drive more economically.
Other factors which decrease gas mileage are:
· Worn or dirty spark plugs
· Incorrect spark plug gap
· Dirty air cleaner
· Dirty engine oil and clogged oil filter
· Dragging brakes
· Incorrect front end alignment
Some of the above mentioned items and others are checked at the standard Maintenance Service intervals.
NOTE : The automatic transmission's ( D)rive position should be used as often as possible to help improve fuel
economy.
WARNING!
It is recommended that tires of the same make and dimensions be used on all four wheels (including the use of
snow tires). Do not use bias ply tires as this will adversely alter vehicle handling characteristics. Maintain correct tire
pressure.
Do not drive with trunk lid open! A warning light in the instrument panel will indicate that the trunk is open.
Poisonous exhaust gases may enter via the open trunk lid. If the trunk lid/tailgate must be kept open for any reason,
proceed as follows:
· Close the windows.
· Set the ventilation system control to air flow to floor, windshield and side windows and blower control to its
highest setting.
