2008 PONTIAC GRAND PRIX towing capacity

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.

Here are some important things to consider before you
do recreational vehicle towing:
What is the towing capacity of the towing vehicle?
Be sure to read the tow vehicle manufacturer’s
recommendations.
How far will the vehicle be towed? Some vehicles
have restrictions on how far and how long they
can tow.
Do you have the proper towing equipment? See
your dealer/retailer or trailering professional for
additional advice and equipment recommendations.
Is the vehicle ready to be towed? Just as you would
prepare your vehicle for a long trip, you will want to
make sure the vehicle is prepared to be towed.
SeeBefore Leaving on a Long Trip on page 4-15.
Dinghy Towing
Notice:If you tow your vehicle with all four wheels
on the ground, the drivetrain components could
be damaged. The repairs would not be covered
by your warranty. Do not tow your vehicle with all
four wheels on the ground.
The vehicle was not designed to be towed with all
four wheels on the ground. If the vehicle must be
towed, use a dolly. See “Dolly Towing” following for
more information.
Dolly Towing
The vehicle can be towed using a dolly. To tow your
vehicle using a dolly, follow these steps:
1. Put the front wheels on the dolly.
2. Put the vehicle in PARK (P).
3. Set the parking brake and then remove the key.
4. Clamp the steering wheel in a straight-ahead
position.
5. Release the parking brake.

Towing a Trailer
{CAUTION:
If you do not use the correct equipment and
drive properly, you can lose control when you
pull a trailer. For example, if the trailer is too
heavy, the brakes may not work well — or
even at all. You and your passengers could
be seriously injured. You may also damage
your vehicle; the resulting repairs would
not be covered by your warranty. Pull a trailer
only if you have followed all the steps in this
section. Ask your dealer/retailer for advice
and information about towing a trailer with
your vehicle.The vehicle can tow a trailer if it is equipped with the
proper trailer towing equipment. 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, 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 pulling 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.
The trailer also adds considerably to wind resistance,
increasing the pulling requirements.

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 the vehicle. The Gross Vehicle Weight (GVW)
includes the curb weight of the vehicle, any cargo
in it, and the people who will be riding in the vehicle.
If there are a lot of options, equipment, passengers
and 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. And if towing
a trailer, the tongue load must be added to the GVW
because the vehicle will be carrying that weight, too.
SeeLoading Your Vehicle on page 4-22for more
information about your vehicle’s maximum load
capacity.When using a weight-carrying hitch or a
weight-distributing hitch, the trailer tongue (A)
should weigh 10 to 15 percent of the total loaded
trailer weight (B).
After the trailer is loaded, weigh the trailer and then
the tongue, separately, to see if the weights are
proper. The correct weight could be achieved simply
by moving some items around in the trailer.
