2005 VOLVO V70 engine

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).
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
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. 89 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.

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.
pg. 90 Refueling
Refueling
The fuel tank holds approximately:
Front wheel drive, non-turbo models - 18.5 US gal. (70 liters)
All turbo models - 18 US gal. (68 liters)
with sufficient volume left over to accommodate possible expansion of the fuel in hot weather. Be aware that the
"usable" tank capacity will be somewhat less than the specified maximum. When the fuel level is low, such factors as
ambient temperature, the fuel's "Reid vapor pressure" characteristics, and terrain can affect the fuel pump's ability to
supply the engine with an adequate supply of fuel. Therefore, it is advisable to refuel as soon as possible when the
needle nears the red zone, or when the fuel warning light comes on.
Fuel filler door
Press the button on the light switch panel (see illustration on page 37
) 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.
If you intend to leave your car while it is being refueled, this features enables you to lock the door/tailgate while
leaving the fuel filler door unlocked.
You can also keep the car locked if you remain inside it during refueling. The central locking button does not lock the
fuel filler door.
Be sure the fuel filler door is not obstructed and is completely closed after refueling.
Open the fuel filler cap slowly during hot weather conditions.
NOTE: During a transitional period, a small number of service stations may still have fuel nozzles that are not
compatible with the fuel filler neck on cars equipped with the evaporative control system. Please refer to page 147

additional information.
WARNING!
Never carry a cell phone that is switched on while refueling your vehicle. If the phone rings, this may cause a spark
that could ignite gasoline fumes, resulting in fire and injury.
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. 91 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 60.
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.
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.
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. While keeping firm pressure on the brake pedal, release the parking
brake.

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. 92 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 or in reverse on models with a manual transmission, 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.
