CADILLAC STS V 2007 1.G Owners Manual

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 of your vehicle.
Your vehicle is not designed nor intended to
tow any trailer.

Refer to your vehicle’s Tire and Loading
Information label for specic information about
your vehicle’s capacity weight and seating
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 is attached to
either the driver’s door edge or the lower center
pillar on the driver’s side of the vehicle. This label
shows the gross weight capacity of your vehicle,
called the Gross Vehicle Weight Rating (GVWR).
Example 3
353

The GVWR includes the weight of the vehicle, all
occupants, fuel, and cargo. The Certication
label also shows the maximum weights for the
front and rear axles, called the Gross Axle Weight
Rating (GAWR). Never exceed the GVWR or
the GAWR for either the front or rear axle.
{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.
{CAUTION:
Things you put inside your vehicle can
strike and injure people in a sudden stop
or turn, or in a crash.
Put things in the trunk of your vehicle.
In a trunk, put them as far forward as
you can. Try to spread the weight
evenly.
Never stack heavier things, like
suitcases, inside the vehicle so that
some of them are above the tops of
the seats.
Do not leave an unsecured child
restraint in your vehicle.
When you carry something inside the
vehicle, secure it whenever you can.
Do not leave a seat folded down unless
you need to.

Towing
Towing Your Vehicle
Consult your dealer or a professional towing
service if you need to have your disabled vehicle
towed. SeeRoadside Service on page 531.
If you want to tow your vehicle behind another
vehicle for recreational purposes (such as behind
a motorhome), see Recreational Vehicle Towing
following.
Recreational Vehicle Towing
Recreational vehicle towing means towing your
vehicle behind another vehicle – such as behind a
motorhome. The two most common types of
recreational vehicle towing are known as “dinghy
towing” (towing your vehicle with all four wheels
on the ground) and “dolly towing” (towing
your vehicle with two wheels on the ground and
two wheels up on a device known as a “dolly”).With the proper preparation and equipment, many
vehicles can be towed in these ways. See
“Dinghy Towing” and “Dolly Towing,” following.
Here are some important things to consider before
you do recreational vehicle towing:
What is the towing capacity of the towing
vehicle? Be sure you read the tow vehicle
manufacturer’s recommendations.
How far will you tow? Some vehicles have
restrictions on how far and how long they
can tow.
Do you have the proper towing equipment?
See your dealer or trailering professional
for additional advice and equipment
recommendations.
Is your vehicle ready to be towed? Just as
you would prepare your vehicle for a long
trip, you will want to make sure your vehicle is
prepared to be towed. SeeBefore Leaving
on a Long Trip on page 340.
355

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.
Your vehicle was not designed to be towed with
all four wheels on the ground. If your vehicle must
be towed, you should use a dolly. See “Dolly
Towing” later in this section for more information.
Dolly Towing (Rear-Wheel-Drive
Vehicles) (STS Only)
Notice:Dolly towing or dinghy towing your
vehicle may cause damage because of reduced
ground clearance. Always tow your vehicle
using the dolly towing or dinghy towing
procedure listed in this section or put your
vehicle on a atbed truck.If your vehicle is a rear-wheel drive, it can be towed
using a dolly. To tow your vehicle using a dolly,
follow these steps:
1. Put the rear wheels on the dolly.
2. Put the vehicle in PARK (P).
356

3. Set the parking brake and then remove the key.
4. Clamp the steering wheel in a straight-ahead
position with a clamping device designed for
towing.
5. Release the parking brake.
Dolly Towing (STS-V)
Notice:Dolly towing or dinghy towing your
vehicle may cause damage because of reduced
ground clearance. Always put your vehicle
on a atbed truck.
If you have an STS-V, it can only be towed on a
at-bed trailer.
Dolly Towing (All-Wheel-Drive Vehicles)
Notice:Towing an all-wheel-drive vehicle
with all four wheels on the ground, or even
with only two of its wheels on the ground, will
damage drivetrain components. Do not tow
an all-wheel-drive vehicle if any of its wheels
will be on the ground.
If you have an All-Wheel Drive (AWD) vehicle, it
can only be towed on a at-bed trailer.
Towing a Trailer
Your vehicle is neither designed nor intended to
tow a trailer.
