Introduction
The park assist system is designed to assist
you when driving into parking spaces, garages,
etc. It utilizes four ultrasound sensors located
in one or both bumpers to measure the dis-
tance to a vehicle, object, or a person who may
be close to the front or rear of your vehicle.
This system is available in the rear bumper
only, or in both the front and rear bumpers.
Park assist utilizes four ultrasound sensors in
the bumper(s) to measure the distance to a
vehicle, object, or a person who may be close
to the front or rear of your vehicle. An audible
signal and symbols in the audio system’s dis-
play indicate the distance to the object
WARNING
Park Assist is an information system, NOT a
safety system. This system is designed to
be a supplementary aid when parking the
vehicle. It is not, however, intended to
replace the driver\fs attention and judge-
ment. Function

202 General information
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:
\b
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.
\b Whenever possible, avoid using the vehicle
for driving short distances. This does not
allow the engine to reach normal operating
temperature.
\b Drive carefully and avoid rapid acceleration
and hard braking.
\b Use the transmission\fs Drive (
D) position
as often as possible and avoid using kick-
down.
\b Do not exceed posted speed limits.
\b Avoid carrying unnecessary items (extra
load) in the vehicle.
\b Maintain correct tire pressure. Check tire
pressure regularly (when tires are cold). \b
Remove snow tires when threat of snow or
ice has ended.
\b Note that roof racks, ski racks, etc,
increase air resistance and also fuel con-
sumption.
\b At highway driving speeds, fuel consump-
tion will be lower with the air conditioning
on and the windows closed than with the
air conditioning off and the windows open.
\b Using the onboard trip computer\fs fuel
consumption modes can help you learn
how to drive more economically.
Other factors that decrease gas mileage
are:
\b Dirty air cleaner
\b Dirty engine oil and clogged oil filter
\b Dragging brakes
\b Incorrect front end alignment
Some of the above mentioned items and others
are checked at the standard maintenance
intervals.
WARNING Driving with the tailgate open: Driving with
the tailgate open could lead to poisonous
exhaust gases entering the passenger com-
partment. If the tailgate must be kept open
for any reason, proceed as follows:
\b
Close the windows
\b Set the ventilation system control to air
flow to floor, windshield and side win-
dows and the blower control to its high-
est setting.
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 cargo area, 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 the
"Tire pressure" section. Loads should be dis-
tributed so that capacity weight or maximum
permissible axle loads are not exceeded.

Driving through water
\b
The vehicle can be driven through water up
to a depth of approximately 10 in. (25 cm),
at a maximum speed of 6 mph (10 km/h).
\b Take particular care when driving through
flowing water.
\b Clean the electrical connections for trailer
wiring after driving in mud or water.
\b 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 \b
Engine damage will occur if water is
drawn into the air cleaner.
\b If the vehicle is driven through water
deeper than 10 in (25 cm), water may
enter the differential and the transmis-
sion. This reduces the oil\fs lubricating
capacity and may shorten the service
life of these components.
\b Do not allow the vehicle to stand in
water up to the door sills longer than
absolutely necessary. This could result
in electrical malfunctions.
\b If the engine has been stopped while the
vehicle is in water, do not attempt to
restart it. Have the vehicle towed out of
the water.
Engine and cooling systemUnder special conditions, for example when
driving in hilly terrain, extreme heat or with
heavy loads, there is a risk that the engine and
cooling system will overheat. Proceed as fol-
lows to avoid overheating the engine.
\b
Maintain a low speed when driving with a
trailer up long, steep hills.
\b Do not turn the engine off immediately
when stopping after a hard drive.
WARNING The cooling fan may start or continue to
operate (for up to 6 minutes) after the engine
has been switched off.
\b
Remove any auxiliary lights from in front of
the grille when driving in hot weather con-
ditions.
\b Do not exceed engine speeds of 4500 rpm
if driving with a trailer in hilly terrain. The oil
temperature could become too high.
Conserving electrical currentKeep the following in mind to help minimize
battery drain:
\bWhen the engine is not running, avoid
using ignition mode
II. Many electrical sys-
tems (the audio system, the optional navi-
gation system, power windows, etc) will
function in ignition modes 0 and I. These
modes reduce drain on the battery.
\b Please keep in mind that using systems,
accessories, etc., that consume a great
deal of current when the engine is not run-
ning could result in the battery being com-
pletely drained.
\b The optional 12 volt socket in the cargo
area provides electrical current even with
the ignition switched off, which drains the
battery.

Before a long distance tripIt is always worthwhile to have your vehicle
checked by a trained and qualified Volvo serv-
ice technician before driving long distances.
Your retailer will also be able to supply you with
bulbs, fuses, spark plugs and wiper blades for
your use in the event that problems occur.
As a minimum, the following items should be
checked before any long trip:
\b
Check that engine runs smoothly and that
fuel consumption is normal.
\b Check for fuel, oil, and fluid leakage
\b Have the transmission oil level checked.
\b Check condition of drive belts.
\b Check state of the battery\fs charge.
\b Examine tires carefully (the spare tire as
well), and replace those that are worn.
Check tire pressures.
\b The brakes, front wheel alignment, and
steering gear should be checked by a
trained and qualified Volvo service techni-
cian only.
\b Check all lights, including high beams.
\b Reflective warning triangles are legally
required in some states/provinces.
\b Have a word with a trained and qualified
Volvo service technician if you intend to
drive in countries where it may be difficult
to obtain the correct fuel. \b
Consider your destination. If you will be
driving through an area where snow or ice
are likely to occur, consider snow tires.
Cold weather precautionsIf you wish to check your vehicle before the
approach of cold weather, the following advice
is worth noting:
\bMake sure that the engine coolant contains
50 percent antifreeze. Any other mixture
will reduce freeze protection. This gives
protection against freezing down to
–31 °F (–35 °C). The use of "recycled" anti-
freeze is not approved by Volvo. Different
types of antifreeze must not be mixed.
\b Volvo recommends using only genuine
Volvo antifreeze in your vehicle\fs radiator.
\b Try to keep the fuel tank well filled – this
helps prevent the formation of condensa-
tion in the tank. In addition, in extremely
cold weather conditions it is worthwhile to
add fuel line de-icer before refueling.
\b The viscosity of the engine oil is important.
Oil with low viscosity (thinner oil) improves
cold-weather starting as well as decreas-
ing fuel consumption while the engine is
warming up. For winter use, 5W-30 oil, par-
ticularly the synthetic type, is recom-
mended. Be sure to use good quality oil but
do not use cold-weather oil for hard driving
or in warm weather, see page 283 for more
information on engine oil.
NOTE Synthetic oil is not used when the oil is
changed at the normal maintenance inter-
vals except at owner request and at addi-
tional charge.
\b
The load placed on the battery is greater
during the winter since the windshield wip-
ers, lighting, etc. are used more often.
Moreover, the capacity of the battery
decreases as the temperature drops. In
very cold weather, a poorly charged bat-
tery can freeze and be damaged. It is there-
fore advisable to check the state of charge
more frequently and spray an anti-rust oil
on the battery posts.
\b Volvo recommends the use of snow tires
on all four wheels for winter driving, see
page 262.
\b To prevent the washer fluid reservoir from
freezing, add washer solvents containing
antifreeze. This is important since dirt is
often splashed on the windshield during
winter driving, requiring the frequent use of
the washers and wipers. Volvo Washer
Solvent should be diluted as follows: Down
to 14 °F (–10 °C): 1 part washer solvent and
4 parts water Down to 5 °F (–15 °C): 1 part
washer solvent and 3 parts water Down to
0 °F (–18 °C): 1 part washer solvent and

206 Fuel requirements
Deposit 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 labeled "UNLEA-
DED". Only these pumps have nozzles which
fit your vehicle\fs filler inlet. It is unlawful to dis-
pense leaded fuel into a vehicle labeled "unlea-
ded 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 affec-
ted, and the Check Engine Light (malfunc-
tion indicator light) located on your instru-
ment panel may light. If this occurs, please
return your vehicle to a trained and qualified
Volvo service technician 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 page 207 must still be met.
Alcohol – EthanolFuels 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.
MethanolDo 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 sys-
tem. Such damage may not be covered under
the New Vehicle Limited Warranty.

Octane rating
Minimum octane
Typical pump octane label
Volvo engines are designed to run on unleaded
gasoline with an octane rating of 87
1
or above.
Please be aware that the engine specifications
for horsepower and torque listed on page
283 are based on the use of premium 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 your engine\fs 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:
\b
standing upwind away from the filler nozzle
while refueling
\b refueling only at gas stations with vapor
recovery systems that fully seal the mouth
of the filler neck during refueling
\b 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\fs 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.

CAUTION\b
Do not refuel with the engine running 2
.
Turn the ignition off or to position I. If the
ignition is on, an incorrect reading could
occur in the fuel gauge.
\b 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. Emission controls
Three-way catalytic converter
\b
Keep your engine properly tuned. Certain
engine malfunctions, particularly involving
the electrical, fuel or distributor ignition
systems, may cause unusually high three-
way catalytic converter temperatures. Do
not continue to operate your vehicle if you
detect engine misfire, noticeable loss of
power or other unusual operating condi-
tions, such as engine overheating or back-
firing. A properly tuned engine will help avoid malfunctions that could damage the
three-way catalytic converter.
\b Do not park your vehicle over combustible
materials, such as grass or leaves, which
can come into contact with the hot exhaust
system and cause such materials to ignite
under certain wind and weather condi-
tions.
\b Excessive starter cranking (in excess of
one minute), or an intermittently firing or
flooded engine can cause three-way cata-
lytic converter or exhaust system over-
heating.
\b Remember that tampering or unauthorized
modifications to the engine, the Engine
Control Module, or the vehicle may be ille-
gal and can cause three-way catalytic con-
verter or exhaust system overheating. This
includes: altering fuel injection settings or
components, altering emission system
components or location or removing com-
ponents, and/or repeated use of leaded
fuel.
NOTE Unleaded fuel is required for vehicles with
three-way catalytic converters.
Heated oxygen sensorsThe heated oxygen sensors monitor the oxy-
gen content of the exhaust gases. Readings
are fed into a control module that continuously
monitors engine functions and controls fuel
injection. The ratio of fuel to air into the engine
is continuously adjusted for efficient combus-
tion to help reduce harmful emissions.

If the fuel filler cap is not closed tightly or if the engine is running\
when the vehicle is refueled, the Check Engine Light (malfunction indi\
cator lamp) may indicate a fault. However, your vehicle\fs
performance will not be affected. Use only Volvo original or approved fu\
el filler caps.
