Alcohol - Ethanol: Fuels containing up to 10% ethanol by volume may be u\
sed. Ethanol may also be
referred to as Ethyl alcohol, or "Gasohol".
Ethers - MTBE: Fuels containing up to 15% MTBE may be used.

Fuel requirements
Octane rating
Volvo engines are designed to achieve rated horsepower, torque, and fuel\
economy performance using
premium 91 octane fuel.
Volvo recommends premium for best performance, but using 87 octane or ab\
ove will not affect engine
reliability.
In demanding driving conditions, such as operating the vehicle in hot we\
ather, towing a trailer, or
driving for extended periods at higher altitudes than normal, it may be \
advisable to switch to higher
octane fuel (91 or higher) or to change gasoline brands to fully utili\
ze your engine's capacity, and for the
smoothest possible operation.

l Rim: The metal support (wheel) for a tire or a tire and tube assembly upo\
n which the tire beads are
seated.
l Maximum load rating: a figure indicating the maximum load in pounds and kilograms that can \
be
carried by the tire. This rating is established by the tire manufacturer\
.
l Maximum permissible inflation pressure: the greatest amount of air pressure that should ever be
put in the tire. This limit is set by the tire manufacturer.
l 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 inf\
lation pressure is affected by the
number of occupants in the vehicle, the amount of cargo, and the speed a\
t which the vehicle will be
driven for a prolonged period. This information can be found on the tire\
inflation placard(s) located on
the driver's side B-pillar or on the inside of the fuel filler door on C\
anadian models, and in the tire
inflation table in this chapter.
l Cold tires: The tires are considered to be cold when they have the same temperatur\
e as the
surrounding (ambient) air. This temperature is normally reached after \
the vehicle has been parked for at
least 3 hours.

Vehicle loading
Properly loading your vehicle will provide maximum return of vehicle des\
ign performance.
Before loading your vehicle, familiarize yourself with the following ter\
ms for determining your vehicle's
weight ratings, with or without a trailer, from the vehicle's Federal/ C\
anadian Motor Vehicle Safety
Standards (FMVSS/CMVSS) label, and the vehicle's tire information plac\
ard:
Curb weight
The weight of the vehicle including a full tank of fuel and all standard\
equipment. It does not include
passengers, cargo, or optional equipment.
Capacity weight
All weight added to the curb weight, including cargo and optional equipm\
ent. When towing, trailer hitch
tongue load is also part of cargo weight.
NOTE: For trailer towing information, please refer to the section "Towing a tr\
ailer" on
page 145.
Permissible axle weight
The maximum allowable weight that can be carried by a single axle (fron\
t or rear). These numbers are
shown on the Federal/Canadian Motor Vehicle Safety Standards (FMVSS/ CM\
VSS) label. The total
load on each axle must never exceed its maximum permissible weight.
Gross vehicle weight (GVW)

The vehicle's curb weight + cargo + passengers.
NOTE:
l The location of the various labels in your vehicle can be found on page 213.
l A table listing important weight limits for your vehicle can be found on\
page 215.
Steps for Determining Correct Load Limit
- Locate the statement "the combined weight of occupants and cargo shoul\
d never exceed XXX pounds"
on your vehicle's placard.
- Determine the combined weight of the driver and passengers that will b\
e riding in your vehicle.
- Subtract the combined weight of the driver and passengers from XXX kil\
ograms 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 five 150 lb. passeng\
ers 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 calculat\
ed 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 capa\
city of
your vehicle.

WARNING!
l Exceeding the permissible axle weight, gross vehicle weight, or any othe\
r weight rating limits can
cause tire overheating resulting in permanent deformation or catastrophi\
c failure.
l Do not use replacement tires with lower load carrying capacities than th\
e tires that were original
equipment on the vehicle because this will lower the vehicle's GVW ratin\
g. Replacement tires with a
higher limit than the originals do not increase the vehicle's GVW rating\
limitations.
