139 Octane rating
Minimum octane
G028920
Typical pump octane label
Volvo recommends premium for best perform-
ance, but using 87 octane1 or above will not
affect engine reliability.
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'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
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 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:
•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.
1AKI (ANTI KNOCK INDEX) is an average of the Research Octane Number (RON) and the Motor Octane Number (MON), MON+RON/2.

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 139 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.
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
"Tire pressure" section.
Loads should be distributed so that capacity
weight or maximum permissible axle loads are
not exceeded.
Conserving electrical currentKeep the following in mind to help minimize
battery drain:
•When the engine is not running, avoid turn-
ing the ignition key to position II (see
page 145). Many electrical systems (the
audio system, the optional infotainment/
navigation systems, power windows, etc)
will function with the ignition key in positionI. This position reduces drain on the bat-
tery.
•Please keep in mind that using systems,
accessories, etc that consume a great deal
of current when the engine is not running
could result in the battery being completely
drained. Driving or having the engine run-
ning for approximately 15 minutes will help
keep the battery charged.
NOTE
A warning message will be displayed in the
text window in the instrument panel when
the battery charge is low.

141 Fuel filler door
G027073
The fuel filler cap can be placed on the hook on
the fuel filler door while refueling
Press the button on the light switch panel (see
the illustration on page 67) 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/tailgate 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.
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 290 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 theneedle nears the red zone, or when the fuel
warning light comes on.
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 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
1.
•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 emis-
sion 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.

147 Driving on rough/unpaved surfaces
The Volvo XC90 is designed primarily for on-
road driving, and it has excellent handling cha-
racteristics on very rough or unpaved roads.
When driving on poorly maintained or unpaved
roads, please keep the following in mind:
•Reduce speed on rough surfaces to mini-
mize possible damage to the vehicle's
underbody.
•When driving on soft surfaces such as dry
sand or snow, try to avoid stopping if at all
possible.
WARNING
•Avoid driving diagonally across steep
inclines as this could increase the risk of
a roll-over. Try to drive straight up or
down the slope.
•If the road is very steep, avoid turning
the vehicle around to help avoid the risk
of rolling over. Back the vehicle up or
down the incline instead.
NOTE
Avoid driving on steep inclines if the fuel
tank is nearly empty. If the flow of fuel to the
engine is interrupted due to the vehicle's
angle of inclination, this could result in dam-
age to the three-way catalytic converter. We
recommend keeping the fuel tank at least
half full when driving on steep inclines.
Driving through water
The vehicle can be driven through water up to
a depth of approximately 16 inches (40 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 18 in (48 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.

06 Starting and driving
Cold weather precautions
06
168
If you wish to check your vehicle before the
approach of cold weather, the following advice
is worth noting:
•Make 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). See section "Coolant".
•The use of "recycled" antifreeze is not
approved by Volvo. Different types of
antifreeze must not be mixed.
•Volvo recommends using only genuine
Volvo antifreeze in your vehicle's radiator.
Your Volvo retailer stocks plenty of Volvo
engine coolant to protect your vehicle dur-
ing cold weather.
•Try to keep the fuel tank well filled – this
prevents the formation of condensation in
the tank. In addition, in extremely cold
weather conditions it is worthwhile to add
fuel line de-icer before refueling.
•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. 0W-30 oil is recommended for
driving in areas with sustained low temper-
atures.
•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 antirust oil on
the battery posts.
•Volvo recommends the use of snow tires
on all four wheels for winter driving – see
section "Wheels and tires."
•To prevent the washer fluid reservoir
from freezing, add washer solvents con-
taining antifreeze (see page 222 for the
location of the washer fluid reservoir). 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 sol-
vent and 3 parts water
•Down to 0 ° F (–18 ° C):1 part washer sol-
vent and 2 parts water
•Down to –18 ° F (–28 ° C): 1 part washer
solvent and 1 part water
•Use Volvo Teflon Lock Spray in the locks.
NOTE
Avoid the use of de-icing sprays as they can
cause damage to the locks.
W – Winter/Wet driving mode – enhanced
vehicle traction
•Mode W will only function if the gear selec-
tor is in the (D)rive position.
•Press the button at the base of the gear
selector to engage/disengage this driving
mode.
•An LED in the button will light up to indicate
that W is engaged and this will also be dis-
played in the instrument panel (see
page 58).
•This mode may be selected for starting/
moving off on slippery roads.

Vehicle loading
07
185
Properly loading your vehicle will provide maxi-
mum return of vehicle design performance.
Before loading your vehicle, familiarize yourself
with the following terms for determining your
vehicle's weight ratings, with or without a
trailer, from the vehicle's Federal/ Canadian
Motor Vehicle Safety Standards (FMVSS/
CMVSS) label, and the vehicle's tire informa-
tion placard.
Curb weightThe weight of the vehicle including a full tank
of fuel and all standard equipment. It does not
include passengers, cargo, or optional equip-
ment.
Capacity weightAll weight added to the curb weight, including
cargo and optional equipment. When towing,
trailer hitch tongue load is also part of cargo
weight.
NOTE
For trailer towing information, please refer to
the section "Towing a trailer."
Permissible axle weightThe maximum allowable weight that can be
carried by a single axle (front or rear). Thesenumbers are shown on the Federal/Canadian
Motor Vehicle Safety Standards (FMVSS/
CMVSS) label. The total load on each axle must
never exceed its maximum permissible weight.
Gross vehicle weight (GVW)The vehicle's curb weight + cargo + passen-
gers.
A table listing important weight limits for your
vehicle, is in chapter "Dimension and weights".
For the location of the various labels in your
vehicle, see page 284
Steps for Determining Correct Load
Limit
•Locate the statement "the combined
weight of occupants and cargo should
never exceed XXX pounds" on your vehi-
cle's placard.
•Determine the combined weight of the
driver and passengers that will be riding in
your vehicle.
•Subtract the combined weight of the driver
and passengers from XXX kilograms or
XXX pounds.
•The resulting figure equals the available
amount of cargo and luggage load
capacity. For example, if the "XXX" amount
equals 1400 lbs. and there will be five150 lb. passengers in your vehicle, the
amount of available cargo and luggage
load capacity is 650 lbs. (1400-750 (5 x
150) = 650 lbs.)
•Determine the combined weight of luggage
and cargo being loaded on the vehicle.
That weight may not safely exceed the
available cargo and luggage load capacity
calculated in Step 4.
•If your vehicle will be towing a trailer, load
from your trailer will be transferred to your
vehicle. Consult this manual
1 to determine
how this reduces the available cargo and
luggage load capacity of your vehicle.
WARNING
•Exceeding the permissible axle weight,
gross vehicle weight, or any other
weight rating limits can cause tire over-
heating resulting in permanent defor-
mation or catastrophic failure.
•Do not use replacement tires with lower
load carrying capacities than the tires
that were original equipment on the
vehicle because this will lower the vehi-
cle's GVW rating. Use only tires with the
correct load carrying capacity. Consult
your Volvo retailer for information.
1For "Towing a trailer" see page 163.

08 Car care
Washing and cleaning the vehicle
08
206
Washing
•The vehicle should be washed at regular
intervals since dirt, dust, insects and tar
spots adhere to the paint and may cause
damage. It is particularly important to wash
the vehicle frequently in the wintertime to
prevent corrosion, when salt has been
used on the roads.
•When washing the vehicle, do not expose
it to direct sunlight. Use lukewarm water to
soften the dirt before you wash with a
sponge, and plenty of water, to avoid
scratching.
•Bird droppings: Remove from paintwork as
soon as possible. Otherwise the finish may
be permanently damaged.
•A detergent can be used to facilitate the
softening of dirt and oil.
CAUTION
Chromed wheels: Clean chrome-plated
wheels using the same detergents used for
the body of the vehicle. Aggressive wheel
cleaning agents can permanently stain
chrome-plated wheels.
•Dry the vehicle with a clean chamois and
remember to clean the drain holes in the
doors and rocker panels.
•Tar spots can be removed with tar remover
after the vehicle has been washed.
•A stiff-bristle brush and lukewarm soapy
water can be used to clean the wiper
blades. Frequent cleaning of the wind-
shield and wiper blades improves visibility
considerably and also helps prolong the
service life of the wiper blades.
•Wash off the dirt from the underside (wheel
housings, fenders, etc.).
•In areas of high industrial fallout, more fre-
quent washing is recommended.
Suitable detergentsSpecial vehicle washing detergents should be
used. A suitable mixture is about 2.5 fl. oz.
(8.5 cl) of detergent to 2.6 US gal. (10 liters) of
warm water. After washing with a detergent the
vehicle should be well rinsed with clean water.
CAUTION
•Avoid waxing or polishing plastic or rub-
ber components
•Polishing chromed strips can wear
away or damage the surface
•Polishes containing abrasive sub-
stances should not be used
CAUTION
•Dirt, snow, etc., on the headlights can
reduce lighting capacity considerably.
Clean the headlights regularly, for
example when refueling.
•During high pressure washing, the
spray mouthpiece must never be closer
to the vehicle than 13 " (30 cm). Do not
spray into the locks.
Special moonroof cautions:
•Always close the moonroof and sun
shade before washing your vehicle.
•Never use abrasive cleaning agents on
the moonroof.
•Never use wax on the rubber seals
around the moonroof.
Exterior componentsVolvo recommends the use of special cleaning
products, available at your Volvo retailer, for
cleaning colored plastic, rubber, or ornamental
components such as chromed strips on the
exterior of your vehicle. The instructions for
using these products should be followed care-
fully. Solvents or stain removers should not be
used.
