load capacity GMC ACADIA 2009 Owner's Manual

If the oor mat has a knob retainer,
a grommet in the oor mat
attaches to a knob on the oor of
the vehicle to secure the oor
mat. To remove the oor mat, turn
the knob till it is aligned with the
slot in the oor mat grommet
and pull the oor mat up. To
reinstall, center the slot in the oor
mat grommet with the knob on
the oor and set the mat in place.
Then turn the knob until it is
perpendicular to the slot in the
grommet to lock the mat in place.Luggage Carrier
{CAUTION
If something is carried on top of
the vehicle that is longer or wider
than the luggage carrier — like
paneling, plywood, or a
mattress — the wind can catch it
while the vehicle is being driven.
This can cause a driver to lose
control. The item being carried
could be violently torn off, and this
could cause a collision, and
damage the vehicle. Items may
be carried inside. Never carry
something longer or wider than
the luggage carrier on top of the
vehicle.
If you have the luggage carrier, you
can load things on top of your
vehicle. Crossrails are not standard
on this vehicle and must be
purchased at your dealer/retailer.Notice:Loading cargo on the
luggage carrier that weighs more
than 200 lbs (91 kg) or hangs
over the rear or sides of the
vehicle can damage the vehicle.
Load cargo so that it rests 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 the Vehicle on
page 4-16.
To prevent damage or loss of cargo
as you are driving, check to make
sure the cargo is still securely
fastened.
Rear Seat Armrest
Vehicles with a rear seat armrest,
have two cupholders. Pull the
armrest down from the rear
seatback to access the cupholders.

Loading the 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/Tire label.{CAUTION
Do not load the 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
the 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 the vehicle.Tire and Loading Information
Label
A vehicle specic Tire and
Loading Information label is
attached to the center pillar
(B-pillar) of your vehicle. With
the driver’s door open, you
will nd the label attached below
the door lock post (striker).
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.
Example Label
4-16 Driving Your Vehicle

The Tire and Loading Information
label also shows the 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 5-35and
Inflation - Tire Pressure on
page 5-41.
There is also important loading
information on the vehicle
Certication/Tire 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/Tire
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’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 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 for your vehicle.

4-18 Driving Your Vehicle

The combined weight of the
driver, passengers, and cargo
should never exceed your
vehicle’s capacity weight.
Certication/Tire Label
A vehicle specic Certication/
Tire label is attached to the rear
edge of the driver’s door.The label shows the gross
weight capacity of your vehicle.
This is called the Gross
Vehicle Weight Rating (GVWR).
The GVWR includes the
weight of the vehicle, all
occupants, fuel, and cargo.
The Certication/Tire label also
tells you the maximum weights
for the front and rear axles, called
the Gross Axle Weight Rating
(GAWR). To nd out the actual
loads on your front and rear
axles, you need to go to a weigh
station and weigh your vehicle.
Your dealer/retailer can help you
with this. Be sure to spread out
your load equally on both sides of
the centerline.Never exceed the GVWR for
your vehicle or the GAWR
for either the front or rear axle.
{CAUTION
Do not load the 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
the 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 the vehicle.
Notice
:Overloading your
vehicle may cause damage.
Repairs would not be covered
by your warranty. Do not
overload your vehicle.

Towing a Trailer
{CAUTION
The driver can lose control when
pulling a trailer if the correct
equipment is not used or the
vehicle is not driven properly.
For example, if the trailer is too
heavy, the brakes may not work
well — or even at all. The driver
and passengers could be
seriously injured. The vehicle may
also be damaged; the resulting
repairs would not be covered by
the vehicle warranty. Pull a trailer
only if all the steps in this section
have been followed. Ask your
dealer/retailer for advice and
information about towing a trailer
with the vehicle.
To identify the trailering capacity of
the vehicle, read the information
in “Weight of the Trailer” that
appears later in this section.Trailering is different than just
driving the 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.
The following information has many
time-tested, important trailering
tips and safety rules. Many of these
are important for the safety of the
driver and the passengers. So
please read this section carefully
before pulling a trailer.
Load-pulling components such as
the engine, transmission, rear
axle, 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. What’s more, the trailer
adds considerably to wind
resistance, increasing the pulling
requirements.
Pulling A Trailer
Here are some important points:
There are many different
laws, including speed limit
restrictions, having to do with
trailering. Make sure the 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.
See “Hitches” later in this section.
Do not tow a trailer at all during
the rst 500 miles (800 km) the
new vehicle is driven. The engine,
axle or other parts could be
damaged.
Then, during the rst 500 miles
(800 km) that a trailer is towed, do
not drive over 50 mph (80 km/h)
and do not make starts at full
throttle. This helps the engine and
other parts of the vehicle wear in
at the heavier loads.
4-24 Driving Your Vehicle

Use the following chart to determine how much the vehicle can weigh, based upon the vehicle model and options.
VehicleMaximum Trailer Weight *GCWR
Front-Wheel Drive 2,000 lbs (907 kg)7,500 lbs (3 402 kg)
Front-Wheel Drive, V92 Trailer Towing Package 4,500 lbs (2 041 kg) 9,500 lbs (4 309 kg)
All-Wheel Drive 2,000 lbs (907 kg)7,700 lbs (3 493 kg)
All-Wheel Drive, V92 Trailer Towing Package 4,500 lbs (2 041 kg)9,700 lbs (4 400 kg)
*The Gross Combination Weight Rating (GCWR) is the total allowable weight of the completely loaded vehicle and
trailer including any passengers, cargo, equipment and conversions. The GCWR for the vehicle should not be
exceeded.
Ask your dealer/retailer for our
trailering information or advice, or
write us at our Customer Assistance
Offices. See Customer 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 gross
weight of the vehicle. The Gross
Vehicle Weight (GVW) includes the
curb weight of the vehicle, any
cargo carried in it, and the people
who will be riding in the vehicle. If there are a lot of options,
equipment, passengers or cargo in
the vehicle, it will reduce the
tongue weight the vehicle can carry,
which will also reduce the trailer
weight the vehicle can tow. If towing
a trailer, the tongue load must be
added to the GVW because
the vehicle will be carrying that
weight, too. See
Loading the Vehicle
on page 4-16 for more information
about the vehicle’s maximum
load capacity. If a weight-carrying hitch or a
weight-distributing hitch is being
used, the trailer tongue (A) should
weigh 10-15 percent of the total
loaded trailer weight (B).
4-26 Driving Your Vehicle

After loading the trailer, weigh the
trailer and then the tongue,
separately, to see if the weights are
proper. If they aren’t, adjustments
might be made by moving some
items around in the trailer.
Trailering may also be limited by the
vehicle’s ability to carry tongue
weight. Tongue weight cannot cause
the vehicle to exceed the GVWR
(Gross Vehicle Weight Rating) or the
RGAWR (Rear Gross Axle Weight
Rating). The effect of additional
weight may reduce the trailering
capacity more than the total of the
additional weight.Consider the following example:
A vehicle model base weight
is 5,500 lbs (2 495 kg); 2,800 lbs
(1 270 kg) at the front axle and
2,700 lbs (1 225 kg) at the rear axle.
It has a GVWR of 7,200 lbs
(3 266 kg), a RGAWR of 4,000 lbs
(1 814 kg) and a GCWR (Gross
Combination Weight Rating)
of 14,000 lbs (6 350 kg). The trailer
rating should be:
Expect tongue weight to be at
least 10 percent of trailer weight
(850 lbs (386 kg)) and because
the weight is applied well behind
the rear axle, the effect on the
rear axle is greater than just
the weight itself, as much as
1.5 times as much. The weight
at the rear axle could be 850 lbs
(386 kg) X 1.5 = 1,275 lbs (578 kg).Since the rear axle already weighs
2,700 lbs (1 225 kg), adding
1,275 lbs (578 kg) brings the total to
3,975 lbs (1 803 kg). This is very
close to, but within the limit for
RGAWR as well. The vehicle is set
to trailer up to 8,500 lbs (3 856 kg).
If the vehicle has many options
and there is a front seat passenger
and two rear seat passengers
with some luggage and gear in the
vehicle as well. 300 lbs (136 kg)
could be added to the front
axle weight and 400 lbs (181 kg) to
the rear axle weight. The vehicle
now weighs:
Weight is still below 7,200 lbs
(3 266 kg) and you might think
700 additional pounds (318 kg)
should be subtracted from the
trailering capacity to stay within
GCWR limits.
