load capacity CHEVROLET AVEO 2004 1.G Owners Manual

Loading Your Vehicle
It is very important to know how much weight your vehicle
can carry. This weight is called the vehicle capacity
weight or maximum load amount and includes the weight
of all occupants, cargo and all nonfactory-installed
options. Two labels on your vehicle show how much
weight it may properly carry, the Tire and Loading
Information label and the Certification label.
{CAUTION:
Do not load your vehicle any heavier than the
GVWR, or either the maximum front or rear
GAWR. If you do, parts on your vehicle can
break, and it can change the way your vehicle
handles. These could cause you to lose
control and crash. Also, overloading can
shorten the life of your vehicle.
Tire and Loading Information Label
A. Vehicle Capacity WeightExample 1 - United States
4-32

The Tire and Loading Information label shows your
vehicle’s seating capacity, the total weight it can properly
carry and the original equipment tire size and the
recommended cold tire inflation pressure for those tires.
For more information on tires and inflation seeTires
on page 5-51andInflation - Tire Pressure on page 5-59.
If your vehicle was purchased in the United States,
the Tire and Loading Information label, Example 1, is
attached to the driver’s side, center pillar, below the door
latch. Vehicles purchased in Canada, will find the Tire
and Loading Information label, Example 2, attached
to the inside of the glove compartment.
There is also important loading information on the
Certification label. It tells you the Gross Vehicle Weight
Rating (GVWR) and the Gross Axle Weight Rating
(GAWR) for the front and rear axle; see “Certification
Label” later in this section.
Example 2 - Canada

Steps for Determining Correct Load Limit
1. If your vehicle has the Tire and Loading Information
label, Example 1, locate the Vehicle Capacity
Weight ”. If your vehicle has the Tire and Loading
Information label, Example 2, locate the “Maximum
Load” amount.
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 Vehicle Capacity Weight
(Example 1-United States) or subtract the combined
weight of the driver and passengers from Maximum
Load (Example 2-Canada).
4. The resulting figure equals the available amount of
cargo and luggage load capacity. For example, if
the Vehicle Capacity Weight or the Maximum Load
amount equals 1400 lbs. (635 kg) and there will
be five 150 lb. (68 kg) passengers in your vehicle,
the amount of available cargo and luggage load
capacity is 650 lbs. (295 kg).
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.

Certication Label
The Certification label, found either on the center pillar,
near the Tire and Loading Information label or on
the end of the driver’s door, tells you the gross weight
capacity of your vehicle, called the Gross Vehicle Weight
Rating (GVWR). The GVWR includes the weight of
the vehicle, all occupants, fuel and cargo. Never exceed
the GVWR for your vehicle, or the Gross Axle Weight
Rating (GAWR) for either the front or rear axle. United States

Tire Size
The following illustration shows an example of a typical
passenger car tire size.
(A) Passenger (P-Metric) Tire:The United States
version of a metric tire sizing system. The letter “P” as
the first character in the tire size means a passenger
vehicle tire engineered to standards set by the U. S. Tire
and Rim Association.(B) Tire Width:The three-digit number indicates the
tire section width in millimeters from sidewall to sidewall.
(C) Aspect Ratio:A two-digit number that indicates
the tire height-to-width measurements. For example,
if the tire size aspect ratio is “70,” as shown in item “C”
of the illustration, it would mean that the tire’s sidewall
is 70% as high as it is wide.
(D) Construction Code:A letter code is used to
indicate the type of ply construction in the tire. The letter
“R” means radial ply construction; the letter “D” means
diagonal or bias ply construction; and the letter “B”
means belted-bias ply construction.
(E) Rim Diameter:Diameter of the wheel in inches.
(F) Service Description:These characters represent
the load range and the speed rating of a tire. The load
range represents the load carry capacity a tire is
certified to carry. The speed rating is the maximum
speed a tire is certified to carry a load. Speed ratings
range from “A” to “Z”.

5-58

Temperature – A, B, C
The temperature grades are A (the highest), B, and C,
representing the tire’s resistance to the generation
of heat and its ability to dissipate heat when tested
under controlled conditions on a specified indoor
laboratory test wheel. Sustained high temperature can
cause the material of the tire to degenerate and
reduce tire life, and excessive temperature can lead to
sudden tire failure. The grade C corresponds to a
level of performance which all passenger car tires must
meet under the Federal Motor Vehicle Safety Standard
No. 109. Grades B and A represent higher levels of
performance on the laboratory test wheel than the
minimum required by law.
Warning: The temperature grade for this tire is
established for a tire that is properly inflated and not
overloaded. Excessive speed, underinflation, or
excessive loading, either separately or in combination,
can cause heat buildup and possible tire failure.
Wheel Alignment and Tire Balance
The wheels on your vehicle were aligned and balanced
carefully at the factory to give you the longest tire life
and best overall performance.
Scheduled wheel alignment and wheel balancing are
not needed. However, if you notice unusual tire wear or
your vehicle pulling one way or the other, the alignment
may need to be reset. If you notice your vehicle
vibrating when driving on a smooth road, your wheels
may need to be rebalanced.
Wheel Replacement
Replace any wheel that is bent, cracked or badly rusted
or corroded. If wheel nuts keep coming loose, the
wheel, wheel bolts and wheel nuts should be replaced.
If the wheel leaks air, replace it (except some
aluminum wheels, which can sometimes be repaired).
See your dealer if any of these conditions exist.
Your dealer will know the kind of wheel you need.
Each new wheel should have the same load-carrying
capacity, diameter, width, offset and be mounted
the same way as the one it replaces.
