Loading specifications
Properly loading your vehicle will provide maxi-
mum return of vehicle design performance.
Weight designations
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 Vehi-
cle Safety Standards (FMVSS/CMVSS) label, and
the vehicle's tire information placard:
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 equipment. When towing,
trailer hitch tongue load is also part of cargo
weight.
Permissible axle weight
The maximum allowable weight that can be car-
ried by a single axle (front or rear). These num-
bers 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 cargo + passengers.
Steps for Determining Correct Load
Limit
1. Locate the statement "the combined weight
of occupants and cargo should never exceed
XXX kg or XXX lbs." on your vehicle's plac-
ard.
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 kg or XXX lbs.
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. pas-
sengers in your vehicle, the amount of availa-
ble 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 to determine
how this reduces the available cargo and lug-
gage load capacity of your vehicle.
WARNING
•
Exceeding the permissible axle weight,
gross vehicle weight, or any other weight
rating limits can cause tire overheating
resulting in permanent deformation 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 vehicle's GVW
rating. Use only tires with the correct load
carrying capacity. Consult your Volvo
retailer for information.
