weight GMC SIERRA 2006 Owner's Guide

For example, adding a 700 lb (318 kg) snow plow
actually adds more than 700 lbs (318 kg) to the front
axle. Using the formula, if the snow plow is 4 ft (122 cm)
in front of the front axle and the wheel base is
10 ft (305 cm), then:
W = 700 lb (318 kg)
A = 4 ft (122 cm)
W.B. = 10 ft (305 cm)
(W x (A + W.B.))/W.B. = (700 x (4 + 10))/10 = 980 lbs
(445 kg)
So, if your truck’s front axle reserve capacity is more
than 980 lbs (445 kg), you could add the snow plow
without exceeding the front GAWR.
Q:What if I want to add heavier equipment to my
vehicle?
A:You can add heavier equipment on the front of the
vehicle if you compensate for it by carrying fewer
passengers, less cargo, or by positioning cargo
towards the rear. This has the effect of reducing
the load on the front. However, the front GAWR,
rear GAWR and the gross vehicle weight
rating (GVWR) must never be exceeded.
{CAUTION:
On some vehicles equipped with certain front
mounted equipment, such as a snow plow, it
may be possible to load the front axle to the
front GAWR but not have enough weight on the
rear axle to have proper braking performance.
If your brakes can not work properly, you could
have a crash. To help your brakes work properly
when a snow plow is installed, always follow
the snow plow manufacturer or installer’s
recommendation for rear ballast to ensure a
proper front and rear weight distribution ratio,
even though the actual front weight may be
less than the front GAWR, and the total vehicle
weight is less than the GVWR. Maintaining a
proper front and rear weight distribution ratio
is necessary to provide proper braking
performance.

Q:What is total vehicle reserve capacity?
A:This is the difference between your GVWR and the
weight of your truck with full fuel and passengers.
It is the amount of weight you can add to your vehicle
before reaching your GVWR. Keep in mind that
reserve capacity numbers are intended as a guide
when selecting the amount of equipment or cargo
your truck can carry. If you are unsure of your
vehicle’s front, rear, or total weight, go to a weigh
station and weigh your vehicle. Your dealer can also
help you with this.
The total vehicle reserve capacity for your vehicle
can be found in the lower right corner of the
Certication/Tire label as shown previously.
See your dealer for additional advice and information
about using a snow plow on your vehicle. Also, see
Loading Your Vehicle on page 4-48.
Emergency Roof Lamp Provisions
Vehicles with the RPO VYU snow plow prep package
also have an emergency roof lamp provision package,
RPO TRW. Wiring for the emergency roof lamp is
provided in the B-pillar as shown. SeeAuxiliary Roof
Mounted Lamp on page 3-18for switch location.

Truck-Camper Loading Information
A vehicle specic Truck-Camper Loading information
label is attached to the inside of your vehicle’s glove box.
This label will tell you if your vehicle can carry a slide-in
camper, how much of a load your vehicle can carry, and
how to correctly spread out the load. Also, it will help you
match the right slide-in camper to your vehicle.
When you carry a slide-in camper, the total cargo load
of your vehicle is the weight of the camper, plus the
following:
Everything else added to the camper after it left the
factory
Everything in the camper
All the people inside
The Cargo Weight Rating (CWR) is the maximum
weight of the load your vehicle can carry. It does not
include the weight of the people inside. But, you
can gure about 150 lbs (68 kg) for each seat.The total cargo load must not be more than your
vehicle’s CWR.
Refer to the Truck-Camper Loading Information label in
the glove box for dimensions A and B as shown in the
following illustration.
Use the rear edge of the load oor for measurement
purposes. The recommended location for the cargo
center of gravity is at point C for the CWR. It is the
point where the mass of a body is concentrated and, if
suspended at that point, would balance the front and rear.
4-59

Here is an example of proper truck and camper match:
A. Camper Center of Gravity
B. Recommended Center of Gravity Location Zone
When the truck is used to carry a slide-in camper,
the total cargo load of the truck consists of the
manufacturer’s camper weight gure, the weight of
installed additional camper equipment not included in
the manufacturer’s camper weight gure, the weight
of camper cargo, and the weight of passengers in the
camper. The total cargo load should not exceed the
truck’s cargo weight rating and the camper’s center of
gravity (A) should fall within the truck’s recommended
center of gravity zone (B) when installed.You must weigh any accessories or other equipment that
you add to your vehicle. Then, subtract this extra weight
from the CWR. This extra weight may shorten the center
of gravity zone of your vehicle. Your dealer can help you
with this.
If your slide-in camper and its load weighs less than the
CWR, the center of gravity zone for your vehicle may be
larger.
Your dealer can help you make a good vehicle-camper
match and help you determine the CWR.
After you have loaded your vehicle and camper, drive
to a weigh station and weigh the front and rear wheels
separately. This will tell you the loads on the axles. The
loads on the front and rear axles should not be more than
either of the Gross Axle Weight Ratings (GAWR). The
total of the axle loads should not be more than the Gross
Vehicle Weight Rating (GVWR).
Open the driver’s door and look at the Certication/Tire
label to nd out your vehicle’s GAWRs and GVWR.
If your vehicle has gone over the weight ratings, move or
take out some things until all the weight falls below the
ratings.
4-60

Secure loose items to prevent weight shifts that could
affect the balance of your vehicle. When the truck-camper
is loaded, drive to a scale and weigh the front and the
rear wheels separately to determine axle loads. Individual
axle loads should not exceed either of the GAWRs. The
total of the front and rear axle loads should not exceed
your vehicle’s GVWR. These ratings are given on the
vehicle certication label attached to the rear edge of
the driver’s door. See “Certication/Tire Label” under
Loading Your Vehicle on page 4-48. If weight ratings are
exceeded, move or remove items to bring all weights
below the ratings.
When you install and load your slide-in camper, check
the manufacturer’s instructions.
If you want more information on curb weights, cargo
weights, Cargo Weight Rating and the correct center of
gravity zone for your vehicle, your dealer can help
you. Just ask for a copy of “Consumer Information,
Truck-Camper Loading.”Pickup Conversion to Chassis Cab
General Motors is aware that some vehicle owners
may consider having the pickup box removed and a
commercial or recreational body installed. Before you do
so, rst contact GM Customer Assistance for information
on such conversions specic to this vehicle. Owners
should be aware that, as manufactured, there are
differences between a chassis cab and a pickup with
the box removed which may affect vehicle safety. The
components necessary to adapt a pickup to permit its
safe use with a specialized body should be installed by a
body builder in accordance with the information available
from GM Customer Assistance. SeeCustomer
Assistance Offices on page 7-4.

Towing a Trailer
Do not tow a trailer during break-in. SeeNew Vehicle
Break-In on page 2-21
{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. Pull a trailer only if you have
followed all the steps in this section. Ask your
dealer for advice and information about towing
a trailer with your vehicle.Notice:Pulling a trailer improperly can damage
your vehicle and result in costly repairs not covered
by your warranty. To pull a trailer correctly, follow
the advice in this part, and see your dealer for
important information about towing a trailer with
your vehicle.
To identify the trailering capacity of your vehicle, you
should read the information in “Weight of the Trailer”
that appears later in this section.
Trailering is different than just driving your vehicle by
itself. Trailering means changes in acceleration, braking,
handling, durability and fuel economy. Successful, safe
trailering takes correct equipment, and it has to be used
properly.
That’s 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 you pull a
trailer.
4-67

If You Do Decide To Pull A Trailer
If you do, here are some important points:
There are many different laws, including speed limit
restrictions, having to do with trailering. Make sure
your rig will be legal, not only where you live but also
where you’ll 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.
Don’t tow a trailer at all during the rst
500 miles (800 km) your new vehicle is driven.
Your engine, axle or other parts could be damaged.
Then, during the rst 500 miles (800 km) that you tow
a trailer, don’t drive over 50 mph (80 km/h) and don’t
make starts at full throttle. This helps your engine
and other parts of your vehicle wear in at the heavier
loads.
If you have an automatic transmission, you can tow
in DRIVE (D). You may want to shift the transmission
to THIRD (3) or, if necessary, a lower gear selection
if the transmission shifts too often, such as under
heavy loads and/or hilly conditions. If you have a
manual transmission and you are towing a trailer,
it’s better not to use the highest gear. SeeTow/Haul
Mode Light on page 3-50.Three important considerations have to do with weight:
The weight of the trailer
The weight of the trailer tongue
The weight on your vehicle’s tires
Tow/Haul Mode
Tow/Haul is a feature on automatic transmission
equipped vehicles that assists when pulling a heavy
trailer or a large or heavy load. SeeTow/Haul Mode
on page 2-31for more information.
Tow/Haul is designed to be most effective when the
vehicle and trailer combined weight is at least 75 percent
of the vehicle’s Gross Combined Weight Rating (GCWR).
See “Weight of the Trailer” later in the section. Tow/Haul
is most useful under the following driving conditions:
When pulling a heavy trailer or a large or heavy load
through rolling terrain.
When pulling a heavy trailer or a large or heavy load
in stop and go traffic.
When pulling a heavy trailer or a large or heavy load
in busy parking lots where improved low speed
control of the vehicle is desired.
4-68

Operating the vehicle in Tow/Haul when lightly loaded
or with no trailer at all will not cause damage. However,
there is no benet to the selection of Tow/Haul when the
vehicle is unloaded. Such a selection when unloaded
may result in unpleasant engine and transmission driving
characteristics and reduced fuel economy. Tow/Haul is
recommended only when pulling a heavy trailer or a large
or heavy load.
Weight of the Trailer
How heavy can a trailer safely be?
It depends on how you plan to use your rig. For example,
speed, altitude, road grades, outside temperature and
how much your vehicle is used to pull a trailer are all
important. It can also depend on any special equipment
that you have on your 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.
Above the 5,000 lb (2 268 kg) trailer rating, the
handling/trailering suspension is required on
C-1500 models and the handling/trailering or
off-road suspension is required on K-1500 models.
Use one of the following charts to determine how much
your vehicle can weigh, based upon your vehicle model
and options.
