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 advisabl\
e to switch to higher octane fuel
(91 or higher) or to change gasoline brands to fully utilize your engi\
ne's capacity, and for the smoothest
possible operation.
NOTE
When switching to higher octane fuel or changing gasoline brands, it may\
be necessary to fill the tank
more than once before a difference in engine operation is noticeable.
Deposit control gasoline (detergent additives)
Volvo recommends the use of detergent gasoline to control engine deposit\
s. Detergent gasoline is
effective in keeping injectors and intake valves clean. Consistent use o\
f deposit control gasolines will help
ensure good drivability and fuel economy. If you are not sure whether th\
e gasoline contains deposit
control additives, check with the service station operator.
NOTE
Volvo does not recommend the use of store-bought fuel injector cleaning \
additives.
Unleaded fuel
Each Volvo has a three-way catalytic converter and must use only unleade\
d gasoline. U.S. and Canadian
regulations require that pumps delivering unleaded gasoline be labelled \
"UNLEADED". Only these
pumps have nozzles which fit your vehicle's filler inlet. It is unlawful\
to dispense leaded fuel into a

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 inflati\
on pressure is affected by the number
of occupants in the car, 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 inflation 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.
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 car has \
been parked for at least 3 hours.

Vehicle loading
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/Ca\
nadian Motor Vehicle Safety
Standards (FMVSS/ CMVSS) label, and the vehicle's tire information pla\
card:
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
146.

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/CMV\
SS) 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 235.
l A table listing important weight limits for your vehicle can be found on\
page
237.
Steps for Determining Correct Load Limit
1. Locate the statement ''the combined weight of occupants and cargo sho\
uld never exceed XXX pounds''
on your vehicle'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 ki\
lograms or XXX pounds.
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. passe\
ngers in your vehicle, the amount
of available cargo and luggage load capacity is 650 lbs. (1400-750 (5 \
x 150) = 650 lbs.)
5. Determine the combined weight of luggage and cargo being loaded on th\
e vehicle. That weight may not
safely exceed the available cargo and luggage load capacity calculated i\
n Step 4.
6. If your vehicle will be towing a trailer, load from your trailer will\
be transferred to your vehicle.
