load capacity CHEVROLET OPTRA 5 2007 1.G Owners Manual

Notice:Loading cargo on the roof rack that
weighs more than 220 lbs (100 kg) or hangs
over the rear or sides of the vehicle may
damage your vehicle. Load cargo so that it
rests on the slats as far forward as possible
and against the side rails, making sure to
fasten it securely.
Do not exceed the maximum vehicle capacity
when loading your vehicle. For more information
on vehicle capacity and loading, seeLoading Your
Vehicle on page 236.
To prevent damage or loss of cargo as you are
driving, check now and then to make sure cargo is
still securely fastened.Rear Seat Armrest
Your vehicle may have a rear seat armrest that
contains two cupholders. To access the
cupholders, pull the armrest down from the rear
seatback.
Convenience Net
The convenience net can help keep small loads
from moving during sharp turns or quick starts and
stops.
Hang the four net hooks in the metal rings on
each corner of the floor.

Tire and Loading Information LabelA vehicle specific tire and loading information label
shows the seating capacity and the maximum
load your vehicle can properly carry. This label
also contains your vehicle’s original equipment tire
size and the recommended tire inflation pressure.
For more information on tires and inflation see
Tires on page 303andInflation - Tire Pressure on
page 311. The tire and loading information label
is attached inside the glove box of the five door
hatchback model. The tire and loading information
label for the wagon is attached to the vehicle’s
center pillar, below the driver’s door latch.
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.

Steps for Determining Correct Load Limit
1. Locate the “Maximum Load” amount
printed on the Tire and Loading Information
label.
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 the maximum load
amount, shown in pounds and kilograms.
4. The resulting figure equals the available
amount of cargo and luggage load capacity.
For example, if the “maximum load” amount
equals 1400 lbs and there will be five 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.

Certication Label
A vehicle specific certification label is attached to
the center pillar, near the driver’s door latch.
This label 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.
And, if you do have a heavy load, you should
spread it out. See “Steps for Determining Correct
Load Limit” earlier in this section.
{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.
Notice:Overloading your vehicle may cause
damage. Repairs would not be covered by your
warranty. Do not overload your vehicle.
If you put things inside your vehicle — like
suitcases, tools, packages, or anything else — they
will go as fast as the vehicle goes. If you have to
stop or turn quickly, or if there is a crash, they will
keep going.

Ination - Tire Pressure
Tires need the correct amount of air pressure to
operate effectively.
Notice:Do not let anyone tell you that
under-ination or over-ination is all right.
It is not. If your tires do not have enough air
(under-ination), you can get the following:
Too much exing
Too much heat
Tire overloading
Premature or irregular wear
Poor handling
Reduced fuel economy
If your tires have too much air (over-ination),
you can get the following:
Unusual wear
Poor handling
Rough ride
Needless damage from road hazardsA vehicle specific tire and loading information
label is attached to your vehicle. This label shows
your vehicle’s original equipment tires and the
correct inflation pressures for your tires when they
are cold. The recommended cold tire inflation
pressure, shown on the label, is the minimum
amount of air pressure needed to support
your vehicle’s maximum load carrying capacity.
For additional information regarding how much
weight your vehicle can carry, and an example
of the tire and loading information label, see
Loading Your Vehicle on page 236. How you load
your vehicle affects vehicle handling and ride
comfort, never load your vehicle with more weight
than it was designed to carry.
When to Check
Check your tires once a month or more. Do not
forget to check the compact spare tire. For
additional information regarding the compact spare
tire, seeCompact Spare Tire on page 334.

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.
If you need to replace any of your wheels,
wheel bolts, or wheel nuts, replace them only with
new GM original equipment parts. This way,
you will be sure to have the right wheel, wheel
bolts, and wheel nuts for your vehicle.{CAUTION:
Using the wrong replacement wheels,
wheel bolts, or wheel nuts on your vehicle
can be dangerous. It could affect the
braking and handling of your vehicle,
make your tires lose air and make you
lose control. You could have a collision
in which you or others could be injured.
Always use the correct wheel, wheel bolts,
and wheel nuts for replacement.
Notice:The wrong wheel can also cause
problems with bearing life, brake cooling,
speedometer or odometer calibration,
headlamp aim, bumper height, vehicle ground
clearance, and tire or tire chain clearance
to the body and chassis.
SeeChanging a Flat Tire on page 324for more
information.
