2009 VOLVO S60 engine

06 Starting and drivingGeneral information

Engine oilAlthough 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 wearingin 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 vehicle during this period.
See page 191 for more information.Fuel requirementsDeposit control gasoline (detergent
additives)Volvo recommends the use of detergent gas-
oline 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 driva-
bility and fuel economy. If you are not sure
whether the gasoline contains deposit control
additives, check with the service station oper-
ator.
NOTE
Volvo does not recommend the use of
external fuel injector cleaning systems.
Unleaded fuelEach Volvo has a three-way catalytic converter
and must use only unleaded gasoline. U.S. and
Canadian regulations require that pumps deliv-
ering unleaded gasoline be labelled "UNLEA-
DED". Only these pumps have nozzles which
fit your vehicle's filler inlet. It is unlawful to dis-
pense 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 effec-
tiveness of the emission control system and
could result in loss of emission warranty cov-
erage. State and local vehicle inspection pro-
grams 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 affec-
ted, and the Check Engine Light (malfunc-
tion indicator lamp) located on your instru-
ment 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 indi-
cating 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 sea-
sonal air quality standards, some areas require
the use of "oxygenated" fuel.
Volvo allows the use of the following "oxygen-
ated" 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 "Gaso-
hol".
Ethers – MTBE: Fuels containing up to 15%
MTBE may be used.

121 Octane rating
Minimum octane
G028920
Typical pump octane labelVolvo recommends premium for best perform-
ance, but using 87 octane or above will not
affect engine reliability.
Volvo engines are designed to achieve rated
horsepower, torque, and fuel economy per-
formance using premium 91 octane fuel.Demanding drivingIn demanding driving conditions, such as oper-
ating the vehicle in hot weather, towing a trailer,
or driving for extended periods at higher alti-
tudes than normal, it may be advisable to
switch to higher octane fuel (91 or higher) or to
change gasoline brands to fully utilize yourengine's capacity, and for the smoothest pos-
sible operation.
NOTE
When switching to higher octane fuel or
changing gasoline brands, it may be neces-
sary to fill the tank more than once before a
difference in engine operation is noticeable.Fuel FormulationsDo not use gasoline that contains lead as a
knock inhibitor, and do not use lead additives.
Besides damaging the exhaust emission con-
trol 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.
Use of AdditivesWith the exception of gas line antifreeze during
winter months, do not add solvents, thicken-
ers, 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.

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.
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.
WARNING
Driving with the trunk open: Driving with
the trunk open could lead to poisonous
exhaust gases entering the passenger com-
partment.
If the trunk must be kept open for any rea-
son, proceed as follows:•
Close the windows
•
Set the ventilation system control to air
flow to floor, windshield and side win-
dows and blower control to its highest
setting.
Fuel filler door
G025967
The fuel filler cap can be placed on the hook on
the fuel filler door while refuelingPress the button on the light switch panel (see
the illustration on page 59) when the vehicle is
at a standstill to unlock the fuel filler door.
Please note that the fuel filler door will remain
unlocked until the vehicle begins to move for-
ward. An audible click will be heard when the
fuel filler door relocks.
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 centrallocking 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.
NOTE
During a transitional period, a small number
of service stations may still have fuel noz-
zles that are not compatible with the fuel
filler neck on vehicles equipped with the
evaporative control system.RefuelingThe fuel tank is designed to accommodate
possible expansion of the fuel in hot weather.
See page 240 for fuel tank volume. Be aware
that the "usable" tank capacity will be some-
what 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 advis-
able to refuel as soon as possible when the
needle nears the red zone, or when the fuel
warning light comes on.

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. Overfill-
ing 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 War-
ranty.
•
Do not use gasolines containing meth-
anol (methyl alcohol, wood alcohol).
This practice can result in vehicle per-
formance deterioration and can dam-
age critical parts in the fuel system.
Such damage may not be covered
under the New Vehicle Limited War-
ranty.
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 engine
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. See pages 94 and 94.1. Fasten the seat belt.
2. Apply the parking brake (hand brake) if not
already set. The gear selector (automatic
transmission) is locked in the (P)ark posi-
tion (SHIFTLOCK).
Manual transmission: the clutch must be
fully depressed.
3. Without touching the accelerator pedal,
turn the ignition key
1to the starting posi-
tion. 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.
NOTE
•
If the key blade section of the remote is
not fully folded out when starting the
vehicle, the immobilizer function may
make it impossible to start the engine.
•
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 tem-
perature as quickly as possible, which
enables them to control emissions and
help reduce the vehicle's impact on the
environment.
•
To release the gear selector from the P
position, the engine must be running (or
the ignition key must be in position II)
and the brake pedal must be
depressed.
•
Select the desired gear. The gear
engages after a very slight delay which
is especially noticeable when selecting
R.
NOTE
Your vehicle is equipped with a KEYLOCK
system (automatic transmission). When the
engine is switched off, the gear selector
must be in the P position before the key can
be removed from the ignition switch.
When starting in cold weather, the trans-
mission may shift up at slightly higher
engine speeds than normal until the auto-
matic transmission fluid reaches normal
operating temperature.
WARNING
An extra mat on the driver's floor can cause
the accelerator pedal to catch. Check that
the movement of the accelerator pedal is
not impeded. No more than one protective
floor covering may be used at one time.
1If 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.

WARNING
Always place the gear selector in Park or in
reverse on models with a manual transmis-
sion, and apply the parking brake before
leaving the vehicle. Never leave the vehicle
unattended with the engine running.
Always open garage doors fully before star-
ting the engine inside a garage to ensure
adequate ventilation. The exhaust gases
contain carbon monoxide, which is invisible
and odorless but very poisonous
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 pre-
mature transmission wear.
SelectingP or N when idling at a standstill
for prolonged periods of time will help pre-
vent overheating of the automatic transmis-
sion fluid.Do not race a cold engine immediately after
starting.

127 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 fol-
lowing rules:•
Bring the engine to normal operating tem-
perature 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 vehicle
for driving short distances. This does 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 vehicle.
•
Maintain correct tire pressure. Check tire
pressure regularly (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 also fuel con-
sumption.
•
Avoid using automatic transmission kick-
down feature unless necessary.
•
However, at higher driving speeds, fuel
consumption will be lower with the air con-
ditioning on and the windows closed than
with the air conditioning off and the win-
dows open.
•
Using the onboard trip computer's fuel
consumption modes can help you learn
how to drive more economically.
Other factors that decrease gas mileage are:
•
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
Vehicles equipped with automatic transmis-
sions should use (D)rive as often as possible
and avoid using "kickdown" to help improve
fuel economy.
CAUTION
Drive slowly and carefully if going through
standing water (i.e. flooded roadways, etc.).
Damage to the engine could result if excess
water is drawn in through the air intake sys-
tem. Never drive the vehicle in water deeper
than 1 foot (300 mm).

06 Starting and drivingHandling and road holding
06128
Weight distribution affects handlingAt the specified curb weight your vehicle has a
tendency to understeer, which means that the
steering wheel has to be turned more than
might seem appropriate for the curvature of a
bend.
This ensures good stability and reduces the
risk of rear wheel skid. Remember that these
properties can alter with the vehicle load.
The heavier the load in the trunk (max. 220 lbs,
100 kg), the less the tendency to understeer.Handling, roadholdingVehicle load, tire design and inflation pressure
all affect vehicle handling. Therefore, check
that the tires are inflated to the recommended
pressure according to the vehicle load. See
"Tire pressure" section.
Loads should be distributed so that capacity
weight or maximum permissible axle loads are
not exceeded.
Speed-sensitive power steering
(Option on certain models)With this feature, the steering is most respon-
sive at lower speeds to make parking, driving
in city traffic, etc., easier. The effect of the
power steering diminishes as you accelerate
for greater stability at highway speeds.Driving through waterThe vehicle can be driven through water up to
a depth of approximately 9 in. (25 cm), at a
maximum speed of 6 mph (10 km/h).
Take particular care when driving through flow-
ing water.
Clean the electrical connections for trailer wir-
ing after driving in mud or water.
When driving through water, maintain low
speed and do not stop in the water.
WARNING
After driving through water, press lightly on
the brake pedal to ensure that the brakes
are functioning normally. Water or mud can
make the brake linings slippery, resulting in
delayed braking effect.
CAUTION
•
Engine damage will occur if water is
drawn into the air cleaner.
•
If the vehicle is driven through water
deeper than 9 in (25 cm), water may
enter the differential and the transmis-
sion. This reduces the oil's lubricating
capacity and may shorten the service
life of these components.
•
Do not allow the vehicle to stand in
water up to the door sills longer than
absolutely necessary. This could result
in electrical malfunctions.
•
If the engine has been stopped while the
car is in water, do not attempt to restart
the engine. Have the car towed out of
the water.
