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
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.

5. Continue to raise the wheel by turning the
crank clockwise. Raise the wheel a little bit
at a time and guide it around the rear axle
until it is securely seated in the storage
area.
6. When it is no longer possible to turn the
crank any further, check that the spare
wheel is securely in position in the storage
compartment.

Jack attachment pointsJack attachmentsThere are two attachment points for the jack on
each side of the vehicle. These attachment
points are under the center of each door.
WARNING
There is an attachment point on each side
of the vehicle located under the pillars
between the front and rear doors. This point
is used during the production process only,
and is NOT intended for attaching the jack.
G020332
WARNING
The undersides of accessory running
boards are not intended for attaching the
jack.
Changing a wheel•
Park the vehicle on a firm, level, non-slip-
pery surface.
•
Engage the parking brake and put the gear
selector in the Park position.
•
Loosen the wheel bolts by exerting down-
ward pressure on the lug wrench.
•
Remove the wheel cap (where applicable)
using the lug wrench in the tool bag.
•
With the wheels still on the ground, use the
lug wrench to loosen the wheel bolts
1/2 – 1 turn. Turn the bolts counterclock-
wise to loosen the bolts.CAUTION
•
The vehicle must not be driven with
wheels of different dimensions or with a
spare tire other than the one that came
with the vehicle. The use of different size
wheels can seriously damage your vehi-
cle's transmission.
•
Correct tightening torque on wheel
bolts must be observed.
•
The wheel bolts should never be
greased or lubricated.
•
Extended, chromed wheel bolts must
not be used with steel rims, as they
make it impossible to fit the hub caps.

Charge air cooler (Intercooler)Turbocharged engines employ a turbo-com-
pressor to force air into the engine inlet mani-
fold and a charge air cooler to cool the
compressed inlet air. The resulting increase in
air flow raises pressure in the intake manifold
and increases engine power over that devel-
oped by the normally-aspirated engine. The
charge air cooler (which resembles a radiator)
is located between the turbo-compressor and
inlet manifold.
Fuel systemThe engine is equipped with a multiport fuel
injection system.
