engine VOLVO S40 2008 Owner's Manual

The brakes, front wheel alignment, and steering gear should be checked by a trained and qualified Volvo service
technician only.
Check all lights, including high beams.
Reflective warning triangles are legally required in some states/provinces.
Have a word with your Volvo retailer if you intend to drive in countries where it may be difficult to obtain the
correct fuel.
Consider your destination. If you will be driving through an area where snow or ice are likely to occur, consider
snow tires.
1To prevent injury from contact with hot surfaces, do not inspect your vehicle's transmission fluid yourself. Have your vehicle's transmission fluid
level inspected by a qualified Volvo service technician.

Fuel requirements
Octane rating
MINIMUM
Volvo recommends premium for best performance, but using 87 octane or above will not affect engine reliability.
Volvo engines are designed to achieve rated horsepower, torque, and fuel economy performance using premium 91
octane fuel.
In demanding driving conditions, such as operating the vehicle in hot weather, towing a trailer, or driving for extended
periods at higher altitudes than normal, it may be advisable to switch to higher octane fuelRECOMMENDED
ProCarManuals.com

(91 or higher) or to change gasoline brands to fully utilize your engine's capacity, and for the smoothest possible
operation.
NOTE
When switching to higher octane fuel or changing gasoline brands, it may be necessary to fill the tank more than
once before a difference in engine operation is noticeable.
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.
NOTE
Volvo does not recommend the use of store -bought fuel injector cleaning additives.
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 vehicle'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
133 06 Starting and driving
Fuel requirements
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
ProCarManuals.com

Check Engine Light (malfunction indicator lamp) located on your instrument panel may light. If this occurs, please
return your vehicle to a trained and qualified Volvo service technician for maintenance.
Gasoline containing alcohol and ethers
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.
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 vehicle, 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
wearing neoprene gloves while handling a fuel filler nozzle.
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 a trained and qualified Volvo service technician for correction.
Use of Additives
With the exception of fuel line antifreeze during winter months, do not add solvents, thickeners, or other store -bought
additives to your vehicle'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.
Fuel filler door
Press the button on the light switch panel (see the illustration on page 59
) with the ignition switched off to unlock the
fuel filler door. Please note that the fuel filler door will remain unlocked until the vehicle begins to move forward. An
audible click will be heard when the fuel filler door relocks.
134 06 Starting and driving
Fuel requirements
ProCarManuals.com

If you intend to leave your vehicle while it is being refueled, this feature enables you to lock the doors/trunk while
leaving the fuel filler door unlocked.
You can also keep the vehicle 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.
Refueling
The fuel tank is designed to accommodate possible expansion of the fuel in hot weather. See page 252
for fuel tank
volume. 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.
CAUTION
Do not refuel with the engine running1. 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 overfilling the fuel tank. Do not press the handle on the filler nozzle more than one extra time. Too much
fuel in the tank in hot weather conditions can cause the fuel to overflow. Overfilling could also cause damage to the
emission control systems.
Avoid spilling gasoline during 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.
1If the fuel filler cap is not closed tightly or if the engine is running when the vehicle 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.

Starting the vehicle
WARNING
Never switch off the ignition (turn the ignition key or start control to position 0) or remove the key or start control
from the ignition switch while the vehicle is in motion. This could cause the steering wheel to lock, which would
make the vehicle impossible to steer.
To start the engine
1. Fasten the seat belt.
WARNING
Before starting, check that the seat, steering wheel and mirrors are adjusted properly. Make sure the brake pedal can
be depressed completely. Adjust the seat if necessary.
2. Apply the parking brake if not already set. The gear selector should be locked in the Park ( P) position (Shiftlock).

.
Manual transmission: the clutch must be fully depressed.
3. The vehicle is equipped with an autostart feature. Without touching the throttle pedal, turn the key to position III
and release it. The starter motor will then operate automatically (for up to ten seconds) until the engine starts. If the
engine fails to start, repeat this step.
NOTE
After a cold start, idle speed may be noticeably higher than normal for a short period. This is done to help bring
components in the emission control system to their normal operating temperature as quickly as possible, which
enables them to control emissions and help reduce the vehicle's impact on the environment.
4. To release the gear selector from the Park ( P) 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. On models with an automatic transmission, the gear engages after a very slight delay which
is especially noticeable when selecting R.
NOTE
Immobilizer : If two of the keys to your vehicle are close together, e.g., on the same key ring when you try to start
the vehicle, this could cause interference in the immobilizer system and result in the vehicle not starting. If this
should occur, remove one of the keys from the key ring before trying to start the vehicle again.
Keylock: Models equipped an automatic transmission have a keylock system. When the engine is switched off, the
gear selector must be in the Park ( P) position before the key can be removed from the ignition switch1.

WARNING
Volvo's floor mats are specially manufactured for your car. They must be firmly secured in the clips on the floor so
that they cannot slide and become trapped under the pedals on the driver's side.
CAUTION
Automatic transmission: 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 of time will help
prevent overheating of the automatic transmission fluid.
WARNING
Always place the gear selector in Park (manual transmission: first or reverse gear) and apply the parking brake
before leaving the vehicle.and apply the parking brake before leaving the vehicle. Never leave the vehicle unattended
with the engine running.

parking brake when the car is stationary with the gear selector in N .
NOTE
If the gear selector is in the Neutral position and the vehicle has been at a standstill for at least 3 seconds, the brake
pedal must be pressed before the gear selector can be moved to another position.
In order to move the gear selector to another position:
1. Turn the ignition key to position II (if the engine is not already running).
2. Depress the brake pedal.
3. Move the gear selector to the desired position.
D - Drive
D is the normal driving position. The Drive position offers 5 forward gears
1. The car automatically shifts between the
various forward gears, based on the level of acceleration and speed. The car must be at a standstill when shifting to
position D from position R .
1T5 models have 6 forward gears.
Manual shifting - Geartronic
The manual shifting mode (Geartronic) can be selected at any time to manually select forward gears, including while
the car is moving.
NOTE
Reverse, Neutral, and Park cannot be selected in Geartronic mode.
To access the ( M)anual shifting position from Drive ( D), move the gear selector to the right to M.
To return to the ( D)rive position from M , move the gear selector to the left.
While driving
If you select the M position while driving, the gear that was being used in the Drive position will also initially be
selected in the M position.
Move the gear selector forward (toward "+") to shift to a higher gear or rearward (toward "-") to shift to a lower
gear.
If you hold the gear selector toward "-", the transmission will downshift one gear at a time and will utilize the
braking power of the engine. If the current speed is too high for using a lower gear, the downshift will not occur until
the speed has decreased enough to allow the lower gear to be used.
If you slow to a very low speed, the transmission will automatically shift down.
