2009 CHEVROLET COBALT load capacity

Loading Your Vehicle
It is very important to know how much weight your
vehicle can carry. This weight is called the vehicle
capacity weight 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 Certication label.
{CAUTION:
Do not load your vehicle any heavier than
the Gross Vehicle Weight Rating (GVWR),
or either the maximum front or rear Gross
Axle Weight Rating (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 specic Tire and Loading Information
label is attached to the vehicle’s center pillar
(B-pillar). With the driver’s door open, you will nd
the label either attached above the door lock
post for a two door vehicle or below the door lock
post for a four door vehicle. The Tire and Loading
Information label shows the number of occupant
seating positions (A), and the maximum vehicle
capacity weight (B) in kilograms and pounds.
Label Example
4-27

The Tire and Loading Information label also shows
the tire size of the original equipment tires (C) and
the recommended cold tire ination pressures (D).
For more information on tires and ination seeTires
on page 5-49andInflation - Tire Pressure on
page 5-56.
There is also important loading information on the
Certication label. It tells you the Gross Vehicle
Weight Rating (GVWR) and the Gross Axle Weight
Rating (GAWR) for the front and rear axle; see
“Certication Label” later in this section.
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 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 kg or XXX lbs.
4.The resulting gure equals the available
amount of cargo and luggage load capacity.
For example, if the “XXX” amount equals
1400 lbs and there will be ve 150 lb
passengers 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 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, the load
from your trailer will be transferred to your
vehicle. Consult this manual to determine how
this reduces the available cargo and luggage
load capacity of your vehicle.
If your vehicle can tow a trailer, seeTowing a
Trailer (Manual Transmission) on page 4-34
orTowing a Trailer (Automatic Transmission)
on page 4-34for important information on
towing a trailer, towing safety rules, and
trailering tips.

Refer to your vehicle’s Tire and Loading
Information label for specic information about

positions.The combined weight of the driver, passengers,
and cargo should never exceed your vehicle’s
capacity weight.
Certication Label
A vehicle specic Certication label, found on the
rear edge 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.

Your vehicle can tow a trailer if it is equipped with the
proper trailer towing equipment. If your vehicle is not
equipped as stated above, do not tow a trailer. To identify
the trailering capacity of your vehicle, you should read the
information in “Weight of the Trailer” that appears later in
this section. Trailering is different than just driving your
vehicle by itself. Trailering means changes in handling,
acceleration, braking, durability and fuel economy.
Successful, safe trailering takes correct equipment, and it
has to be used properly.
That is the reason for this part. In it are many
time-tested, important trailering tips and safety rules.
Many of these are important for your safety and that of
your passengers. So please read this section carefully
before you pull a trailer.
Load-pulling components such as the engine,
transmission, wheel assemblies and tires are forced to
work harder against the drag of the added weight.
The engine is required to operate at relatively higher
speeds and under greater loads, generating extra heat.
Also, the trailer adds considerably to wind resistance,
increasing the pulling requirements.If You Do Decide To Pull A Trailer
If you do, here are some important points:
There are many different laws, including speed limit
restrictions, having to do with trailering. Make sure
your rig will be legal, not only where you live but
also where you will be driving. A good source for this
information can be state or provincial police.
Consider using a sway control. You can ask a hitch
dealer about sway controls.
Do not tow a trailer at all during the rst 1,000 miles
(1 600 km) your new vehicle is driven. Your engine,
axle or other parts could be damaged.
Then, during the rst 500 miles (800 km) that you tow
a trailer, do not drive over 50 mph (80 km/h) and do
not make starts at full throttle. This helps your engine
and other parts of your vehicle wear in at the
heavier loads.
Obey speed limit restrictions when towing a trailer.
Do not drive faster than the maximum posted speed
for trailers, or no more than 55 mph (90 km/h), to
save wear on your vehicle’s parts.
Do not tow when the outside air temperature is
above 100°F (38°C).
Do not tow more than 1,000 miles (1 600 km)
per year.

Three important considerations have to do with weight:
The weight of the trailer
The weight of the trailer tongue
The total weight on your vehicle’s tires
Weight of the Trailer
How heavy can a trailer safely be?
It should never weigh more than 1,000 lbs (450 kg).
But even that can be too heavy.
It depends on how you plan to use your rig. For
example, speed, altitude, road grades, outside
temperature and how much your vehicle is used to pull
a trailer are all important. It can also depend on any
special equipment that you have on your vehicle,
and the amount of tongue weight the vehicle can carry.
See “Weight of the Trailer Tongue” later in this
section for more information.
Maximum trailer weight is calculated assuming only the
driver is in the tow vehicle and it has all the required
trailering equipment. The weight of additional optional
equipment, passengers and cargo must be subtracted
from the maximum trailer weight.
Ask your dealer/retailer for our trailering information
or advice, or write us at our Customer Assistance
Offices. SeeCustomer Assistance Offices on page 7-5
for more information.
Weight of the Trailer Tongue
The tongue load (A) of any trailer is an important weight
to measure because it affects the total or gross weight
of your vehicle. The Gross Vehicle Weight (GVW)
includes the curb weight of the vehicle, any cargo you
may carry in it, and the people who will be riding in the
vehicle. If you have a lot of options, equipment,
passengers, or cargo in your vehicle, it will reduce the
tongue weight your vehicle can carry, which will also
reduce the trailer weight your vehicle can tow. And if you
tow a trailer, you must add the tongue load to the GVW
because your vehicle will be carrying that weight, too.
SeeLoading Your Vehicle on page 4-27for more
information about your vehicle’s maximum load capacity.
If you are using a weight-carrying hitch, the trailer
tongue (A) should weigh 10 to 15 percent of the total
loaded trailer weight (B).
