Minimum octane
G028920
Typical pump octane labelVolvo recommends premium fuel for best per-
formance, 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.

IntroductionVolvo recommends the use of Volvo trailer
hitches that are specially designed for the vehi-
cle.
NOTE
See page 271 for the maximum trailer and
tongue weights recommended by Volvo.•
Observe the legal requirements of the
state/province in which the vehicles are
•
All Volvo models are equipped with
energy-absorbing shock-mounted bump-
ers. Trailer hitch installation should not
interfere with the proper operation of this
bumper system.
Trailer towing does not normally present any
particular problems, but take into considera-
tion:
•
Increase tire pressure to recommended
full. See the tire inflation tables on pages
248 and 249.
•
When your vehicle is new, avoid towing
heavy trailers during the first 620 miles
(1,000 km).
•
Maximum speed when towing a trailer:
50 mph (80 km/h).
•
Engine and transmission are subject to
increased loads. Therefore, engine coolant
temperature should be closely watchedwhen driving in hot climates or hilly terrain.
Use a lower gear and turn off the air con-
ditioner if the temperature gauge needle
enters the red range.
•
If the automatic transmission begins to
overheat, a message will be displayed in
the text window.
•
Avoid overload and other abusive opera-
tion.
•
Hauling a trailer affects handling, durabil-
ity, and economy.
•
It is necessary to balance trailer brakes
with the towing vehicle brakes to provide a
safe stop (check and observe state/local
regulations).
•
Do not connect the trailer's brake system
directly to the vehicle's brake system.
•
More frequent vehicle maintenance is
required.
•
Remove the ball and drawbar assembly
when the hitch is not being used.
•
Volvo recommends the use of synthetic
engine oil when towing a trailer over long
distances or in mountainous areas.
WARNING
•
Bumper-attached trailer hitches must
not be used on Volvos, nor should
safety chains be attached to the
bumper.
•
Trailer hitches attaching to the vehicle
rear axle must not be used.
•
Never connect a trailer's hydraulic
brake system directly to the vehicle
brake system, nor a trailer's lighting
system directly to the vehicle lighting
system. Consult your nearest author-
ized Volvo retailer for correct installa-
tion.
•
When towing a trailer, the trailer's safety
wire must be correctly fastened to the
hole or hook provided in the trailer hitch
on the vehicle. The safety wire should
never be fastened to or wound around
the drawbar ball.

NOTE
•
When parking the vehicle with a trailer
on a hill, apply the parking brake before
putting the gear selector in P. Always
follow the trailer manufacturer's recom-
mendations for wheel chocking.
•
When starting on a hill, put the gear
selector in D before releasing the park-
ing brake. See also page 115 for more
detailed information about starting off
on a hill while towing a trailer.
•
If you use the manual (Geartronic) shift
positions while towing a trailer, make
sure the gear you select does not put
too much strain on the engine (using too
high a gear).
•
The drawbar assembly/trailer hitch may
be rated for trailers heavier than the
vehicle is designed to tow. Please
adhere to Volvo's recommended trailer
weights.
•
Avoid driving with a trailer on inclines of
more than 15 %.
Trailer cableAn adapter is required if the vehicle's trailer
hitch has a 13-pin connector and the trailer has
7 pins. Use an adapter cable approved by
Volvo. Make sure the cable does not drag on
the ground.

Attaching the towing eyeletThe towing eyelet is located under the floor of
the cargo area, with the spare tire. This eyelet
must be screwed into the positions providedon the right sides of either the front or rear
bumper (see illustration).
CAUTION
If the vehicle is being towed on a flat bed
truck, the towing eyelets must not be used
to pull the vehicle up onto the flat bed.
NOTE
On certain models equipped with a trailer
hitch, the towing eyelet cannot be screwed
into the hole in the rear bumper. The towing
rope should be attached to the trailer hitch
instead. For this reason, the detachable
section of the trailer hitch should be safely
stowed in the vehicle at all times.Attaching the towing eyelet

should be removed and returned to its storage
location.
Press the cover for the attachment point back
into position.WARNING
If the vehicle has no electrical current and
must be towed, the power steering and
brake systems will not function normally. It
will still be possible to steer the vehicle and
apply the brakes. However, keep in mind
that greater effort will be required to turn the
steering wheel and depress the brake pedal.Precautions when the vehicle is in tow•
The steering wheel must be unlocked. The
remote key must be in the ignition slot
1.
•
Attach jumper cables (see page 105) to
provide current for releasing the optional
electric parking brake and to move the gear
selector from the P position.

•
Maximum load rating: a figure indicating
the maximum load in pounds and kilo-
grams that can be carried by the tire. This
rating is established by the tire manufac-
turer.
•
Maximum permissible inflation
pressure: the greatest amount of air pres-
sure that should ever be put in the tire. This
limit is set by the tire manufacturer.
•
Recommended tire inflation pressure:
inflation pressure, established by Volvo,
which is based on the type of tires that are
mounted on a vehicle at the factory. This
inflation pressure is affected by the number
of occupants in the vehicle, the amount of
cargo, and the speed at which the vehicle
will be driven for a prolonged period. This
information can be found on the tire infla-
tion placard(s) located on the driver's side
B-pillar or on the inside of the fuel filler door
on Canadian models, and in the tire infla-
tion table in this chapter.
•
Cold tires: The tires are considered to be
cold when they have the same temperature
as the surrounding (ambient) air. This tem-
perature is normally reached after the vehi-
cle has been parked for at least 3 hours.
Vehicle loadingProperly 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", see
page 210.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.
NOTE
•
The location of the various labels in your
vehicle can be found on page 266.
•
A table listing important weight limits for
your vehicle can be found on page
271.
Steps for Determining Correct Load
Limit1. Locate the statement "the combined
weight of occupants and cargo should
never exceed XXX pounds" on your vehi-
cle's placard.
2. Determine the combined weight of the
driver and passengers that will be riding in
your vehicle.
3. Subtract the combined weight of the driver
and passengers from XXX kilograms or
XXX pounds.

06 Maintenance and specificationsWheels and tires
06252
4. 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 five
150 lb. passengers in your vehicle, the
amount of available cargo and luggage
load capacity is 650 lbs. (1400 – 750
(5 × 150) = 650 lbs.)
5. 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.
6. 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. Replacement tires
with a higher limit than the originals do
not increase the vehicle's GVW rating
limitations.
Uniform Tire Quality GradingALL PASSENGER VEHICLE TIRES MUST
CONFORM TO FEDERAL SAFETY
REQUIREMENTS IN ADDITION TO THESE
GRADES
Quality grades can be found, where appli-
cable, on the tire sidewall between the tread
shoulder and maximum section width. For
example:
Treadwear 200 Traction AA Temperature A
TREADWEARThe treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov-
ernment test course. For example, a tire gra-
ded 150 would wear one and one half (1 1/2)
times as well on the government course as a
tire graded 100. The relative performance of
tires depends upon the actual conditions of
their use, however, and many depart signifi-
cantly from the norm due to variation in driving
habits, maintenance practices and differences
in road characteristics and climate.TRACTIONThe traction grades, from highest to lowest, are
AA, A, B, and C, as measured under controlled
conditions on specified government test sur-
faces of asphalt and concrete. A tire marked C
may have poor traction performance. The trac-
tion grade assigned to this tire is based on
braking (straight-ahead) traction tests and is
not a measure of cornering (turning) traction.
WARNING
The traction grade assigned to this tire is
based on braking (straight-ahead) traction
tests and is not a measure of cornering
(turning) traction.

06``273 Engine oil
Engine oil must meet the minimum ILSAC
specification GF-4, API SL, or ACEA A1/B1.
Lower quality oils may not offer the same fuel
economy, engine performance, or engine pro-
tection.
Volvo recommends Castrol.
Depending on your driving habits, premium or
synthetic oils may provide superior fuel econ-
omy and engine protection. Consult your Volvo
retailer for recommendations on premium or
synthetic oils.
Oil additives must not be used.
Synthetic oil is not used when the oil is
changed at the normal maintenance services.
This oil is only used at customer request, at
additional charge. Please consult your Volvo
retailer.Oil viscosity (stable ambient
temperatures)
Operation in hot climatesWhen temperatures exceed 104 °F (40 °C) in
your area, Volvo recommends, for the protec-
tion of your engine, that you use a heavierweight oil, such as such as SAE 5W-40 or
0W-40. See the viscosity chart.
G023491
Viscosity tableOperation in temperate climatesIncorrect viscosity oil can shorten engine life.
Under normal use when temperatures do not
exceed 104 °F (40 °C), SAE 5W-30 will provide
good fuel economy and engine protection. See
the viscosity chart.Extreme engine operationSynthetic oils meeting SAE 0W-30 or 0W-40
and complying with oil quality requirements are
recommended for driving in areas of sustained
temperature extremes (hot or cold), when tow-ing a trailer over long distances, and for pro-
longed driving in mountainous areas.

The API Service Symbol "donut" is divided into
three parts:•
The upper section describes the oil's per-
formance level.
•
The center identifies the oil's viscosity.
•
The lower section indicates whether the oil
has demonstrated energy-conserving
properties in a standard test in comparison
to a reference oil.
