2003 VOLVO V70 check engine light

Anti-lock Brake System (ABS)
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 filler door
Press the button on the light switch panel (see page 34
) when the car is at a standstill to unlock the fuel filler door.
Please note that the fuel filler door will remain unlocked until the car begins to move forward. An audible click will be
heard when the fuel filler door relocks.
Fuel filler cap
After refueling, close the fuel filler cap by turning it clockwise until it clicks into place. If this cap is not closed tightly
or if the engine is running when the car is refueled, the Malfunction Indicator Lamp ("Check Engine" light) may
indicate a fault.

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 Front airbags - SRS
A self -diagnostic system incorporated in the sensor monitors the SRS. This system does not, however, monitor the
Side Impact Protection System (SIPS) airbags. If a fault is detected, the 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 key is turned to positions I, II or III and should go out after 7 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.

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.
Canadian models are equipped with this warning light:
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.
Anti-lock Brake System ABS
If the warning light comes on, there is a malfunction of the ABS system (the standard braking system will still
function). The vehicle should be driven to a Volvo retailer for inspection. See page 19
for additional information.
Stability Traction Control (STC) system (option), or Dynamic Stability and
Traction Control (DSTC) system (option)
An indicator light will flash when STC or DSTC is actively working to stabilize the car. See pages 20-21 for more
detailed information.

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).
Deposit control gasoline (detergent additives)
Volvo recommends the use of gasoline containing deposit control additives. These additives have shown to be
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 methyl-cyclopentadienyl
manganese tricarbonyl (MMT). If such fuels are used, your Emission Control System performance may be affected,
and the Check Engine light (malfunction indicator lamp) located on your instrument panel may light. If this occurs,
please return your vehicle to an authorized Volvo retailer for service.
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.
CAUTION! 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.
pg. 85 Fuel requirements
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.

additional information.
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 when refueling. In addition to causing damage to the environment, 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.
* If the fuel filler cap is not closed tightly or if the engine is running when the car is refueled, the Check Engine light
(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.
pg. 87 Starting the engine
Starting the engine
1. Fasten the seat belt.
WARNING!
Before starting, check that the seat, steering wheel and mirrors adjusted properly. Make sure the brake pedal can be
depressed completely. Adjust the seat if necessary. See page 56.
2. Apply the parking brake, if not already set. The gear selector ( automatic transmission) is locked in the (P)ark
position ( SHIFT -LOCK ). Manual transmission: the clutch must be fully depressed.
3. Without touching the accelerator pedal, turn the ignition key* to the starting position. Allow the starter to operate
for up to 10 seconds. Release the key as soon as the engine starts. If the engine fails to start, repeat this step.
For cold starts at altitudes above 6000 ft (1800 meters), depress the accelerator pedal halfway and turn the key to the
starting position. Release the pedal slowly when the engine starts.
NOTE:
On certain models, when the car is started, idle speed may be noticeably higher than normal for a short period,
depending on the temperature of the engine.
This has been done to help bring components in the emission control system to their normal operating temperature as
quickly as possible, which enables them to function normally.
4. To release the gear selector from the (P)ark position, the engine must be running (or the ignition key must be in
position II) and the brake pedal must be depressed.
5. Select the desired gear. The gear engages after a very slight delay which is especially noticeable when selecting R.
NOTE:
Your car is equipped with a KEYLOCK system. When the engine is switched off, the gear selector must be in the
(P)ark position before the key can be removed from the ignition switch.

When starting in cold weather, the transmission may shift up at slightly higher engine speeds than normal until the
automatic transmission fluid reaches normal operating temperature.
* Your car is equipped with an electronic start inhibitor (immobilizer). The keys you received with your car are
specially coded. The code in the key is transmitted to an antenna in the ignition switch where it is compared to the
code stored in the start inhibitor module. The car can only be started if a properly coded key is used.
If two of the keys to your car are close together, e.g., on the same key ring, when you try to start the car, this could
cause interference in the immobilizer system and result in the car not starting. If this should occur, remove one of the
keys from the key ring before trying to start the car again.
pg. 88 Starting the engine
CAUTION:
The engine should be idling when you move the gear selector. Never accelerate until after you feel the transmission
engage! Accelerating immediately after selecting a gear will cause harsh engagement and premature transmission wear.
Selecting P or N when idling at a standstill for prolonged periods time will help prevent overheating of the automatic
transmission fluid.
Do not race a cold engine immediately after starting. Oil flow may not reach some lubrication points fast enough to
prevent engine damage.
WARNING!
Always place the gear selector in Park and apply the parking brake before leaving the vehicle. Never leave the car
unattended with the engine running.
Always open garage doors fully before starting the engine inside a garage to ensure adequate ventilation. The
exhaust gases contain carbon monoxide, which is invisible and odorless but very poisonous.
An extra mat on the driver's floor can cause the accelerator pedal and the clutch to catch. Check that the movement
of the accelerator pedal and clutch is not impeded. Not more than one protective floor covering may be used at one
time.
