2011 CADILLAC DTS load capacity

Black plate (18,1)Cadillac DTS Owner Manual - 2011
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 Certification
label.
{WARNING:
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 the 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
Label Example
A vehicle specific Tire and Loading Information
label is attached to the vehicle's center pillar
(B-pillar). With the driver's door open, you will
find 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.

The Tire and Loading Information label also
shows the tire size of the original equipment
tires (C) and the recommended cold tire inflation
pressures (D). For more information on tires and
inflation seeTires
on page 6‑48andInflation - Tire
Pressure
on page 6‑57.
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.
If you have a Professional Vehicle, a Tire and
Loading Information label specific to your vehicle
will be provided and installed by the final body
manufacturer. The Tire and Loading Information
label, should be attached to the B‐pillar of your
vehicle. See the final stage manufacturer's
manual or contact them directly. The label shows
the original tires installed on your professional
vehicle and the recommended cold tire inflation
pressures for those tires. The label also tells you
the professional vehicle's capacity weight.
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 figure equals the available
amount of cargo and luggage load capacity.
For example, if the“XXX”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).
5-19

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, see“Towing a
Trailer” for important information on towing a
trailer, towing safety rules, and trailering tips.

Refer to your vehicle's Tire and Loading
Information label for specific 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.
Certification Label
A vehicle specific Certification label is attached
to the rear edge of the driver's door. This label
shows 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.
If your vehicle is a Professional Vehicle,
the vehicle specific Certification label is
provided by the final stage manufacturer. The
coach‐builder should be consulted if the final
stage manufacturer's label is not present. The
Gross Vehicle Weight Rating GVWR label should
be on the driver's door edge.
If you do have a heavy load, you should spread it
out. See
“Steps for Determining Correct Load
Limit” earlier in this section.

Notice:Pulling a trailer improperly can damage the
vehicle and result in costly repairs not covered by
the vehicle warranty. To pull a trailer correctly,
follow the advice in this section and see your dealer
for important information about towing a trailer with
the 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,
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, axles, 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.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.
.Do not tow a trailer at all during the
first 1,000 miles (1600 km) the new vehicle
is driven. The engine, transmission or other
parts could be damaged. The repairs would
not be covered by the vehicle's warranty.
.Then, during the first 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.
.Vehicles can tow in D (Drive). Shift the
transmission to a lower gear if the transmission
shifts too often under heavy loads and/or hilly
conditions.
.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 the vehicle's parts.
5-27

Black plate (28,1)Cadillac DTS Owner Manual - 2011
.Do not tow a trailer when the outside temperature
is above 100°F (38°C).
.If the vehicle has the Side Blind Zone Alert (SBZA)
system and it doesn't seem to be working properly
while pulling a trailer, turn the system off. SeeSide
Blind Zone Alert (SBZA)
on page 3‑42for more
information.
Three important considerations have to do with weight:
.The weight of the trailer
.The weight of the trailer tongue
.The total weight on the vehicle's tires
Weight of the Trailer
How heavy can a trailer safely be?
It should never weigh more than 1,000 lbs (454 kg). But
even that can be too heavy.
It depends on how the rig is used. For example,
speed, altitude, road grades, outside temperature and
how much the vehicle is used to pull a trailer are all
important. It can depend on any special equipment
on the 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 in the tow vehicle
must be subtracted from the maximum trailer weight.
Ask your dealer for trailering information or advice,
or write us at our Customer Assistance Offices. See
Customer Assistance Offices
on page 8‑6for 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 5‑18for more information about the vehicle's
maximum load capacity.

(C) Aspect Ratio:A two‐digit number that
indicates the tire height‐to‐width measurements.
For example, if the tire size aspect ratio is 60, as
shown in item C of the illustration, it would mean
that the tire's sidewall is 60 percent as high as it
is wide.
(D) Construction Code
:A letter code is used to
indicate the type of ply construction in the tire.
The letter R means radial ply construction; the
letter D means diagonal or bias ply construction;
and the letter B means belted‐bias ply
construction.
(E) Rim Diameter
:Diameter of the wheel in
inches.
(F) Service Description
:These characters
represent the load index and speed rating of the
tire. The load index represents the load carry
capacity a tire is certified to carry. The speed
rating is the maximum speed a tire is certified to
carry a load.
Light Truck (LT‐Metric) Tire
(A) Light Truck (LT‐Metric) Tire:The United
States version of a metric tire sizing system. The
letters LT as the first two characters in the tire size
means a light truck tire engineered to standards
set by the U.S. Tire and Rim Association.
(B) Tire Width
:The three‐digit number indicates
the tire section width in millimeters from sidewall
to sidewall.
(C) Aspect Ratio
:A two‐digit number that
indicates the tire height‐to‐width measurements.
For example, if the tire size aspect ratio is 75, as
shown in item C of the light truck (LT‐Metric) tire
illustration, it would mean that the tire's sidewall is
75 percent as high as it is wide.

(D) Construction Code:A letter code is used to
indicate the type of ply construction in the tire.
The letter R means radial ply construction; the
letter D means diagonal or bias ply construction;
and the letter B means belted‐bias ply
construction.
(E) Rim Diameter
:Diameter of the wheel in
inches.
(F) Load Range
:Load Range.
(G) Service Description
:The service description
indicates the load index and speed rating of a
tire. If two numbers are given as in the example,
120/116, then this represents the load index for
single versus dual wheel usage (single/dual).
The speed rating is the maximum speed a tire is
certified to carry a load.
Tire Terminology and Definitions
Air Pressure:The amount of air inside the tire
pressing outward on each square inch of the tire.
Air pressure is expressed in pounds per square
inch (psi) or kilopascal (kPa). Accessory Weight
