of the driver, passengers, and
cargo should never exceed the
vehicle's capacity weight.
Certification/Tire Label
A vehicle-specific Certification/
Tire label is label is attached to
the center pillar (B-pillar). The
label may show the size of the
vehicle's original tires and the
inflation pressures needed to
obtain the gross weight capacity
of the vehicle. This is called
Gross Vehicle Weight
Rating (GVWR). The GVWRincludes the weight of the
vehicle, all occupants, fuel, and
cargo.
The Certification/Tire label also
may show the maximum weights
for the front and rear axles,
called Gross Axle Weight
Rating (GAWR). To determine
the actual loads on the front and
rear axles, weigh the vehicle at
a weigh station. Your dealer can
help with this. Be sure to spread
the load equally on both sides of
the centerline.
The Certification/Tire label also
contains important information
about the Front Axle Reserve
Capacity. See
Adding a Snow
Plow or Similar Equipment
0 319.
{Warning
In the case of a sudden stop
or collision, things carried in
the bed of your truck could
shift forward and come into
the passenger area, injuring
you and others. If you put
things in the bed of your truck,
you should make sure they
are properly secured.
Caution
Overloading the vehicle may
cause damage. Repairs would not
be covered by the vehicle
warranty. Do not overload the
vehicle.
Using heavier suspension
components to get added
durability might not change the
weight ratings. Ask your dealer
to help load the vehicle the
right way.

{Warning
Things you put inside the
vehicle can strike and injure
people in a sudden stop or
turn, or in a crash.
.Put things in the cargo
area of the vehicle. 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 the vehicle.
.When you carry
something inside the
vehicle, secure it
whenever you can.
.Do not leave a seat
folded down unless you
need to. There is also important loading
information for off-road driving in
this manual. See
“Loading the
Vehicle for Off-Road Driving“
under Off-Road Driving 0188.
Two-Tiered Loading
Depending on the model of the
pickup, an upper load platform
can be created by positioning
three or four 5 cm (2 in) by
15 cm (6 in) wooden planks
across the width of the pickup
box. The planks must be
inserted in the pickup box
depressions.
When using this upper load
platform, be sure the load is
securely tied down to prevent it
from shifting. The load's center
of gravity should be positioned
in a zone over the rear axle. The
zone is located in the area
between the front of each wheel
well and the rear of each wheel well. The center of gravity height
must not extend above the top
of the pickup box flareboard.
Any load that extends beyond
the vehicle's taillamp area must
be properly marked according to
local laws and regulations.
Remember not to exceed the
Gross Axle Weight
Rating (GAWR) of the front or
rear axle.
Add-On Equipment
When carrying removable items,
a limit on how many people
carried inside the vehicle may
be necessary. Be sure to weigh
the vehicle before buying and
installing the new equipment.

Structural members (1) and (2) are
included in the pickup box design.
Additional accessories should use
these load points. Depending on the
accessory design, use a spacer
under the accessory at the load
points to remove gap. The holes for
GM approved accessories (3) are
not intended for aftermarket equipment. See www.gmupfitter.com
for additional pickup box load
bearing structural information.
Truck-Camper Loading
Information
A vehicle-specific Truck-Camper
Loading Information label is
attached to the inside of the
vehicle's glove box. This label
indicates if a slide-in camper
can be carried, how much of a
load the vehicle can carry, and
how to correctly spread out the
load. It will help to match the
right slide-in camper to the
vehicle.
Your dealer can help make a
good vehicle-camper match and
help determine the Cargo
Weight Rating (CWR).
When installing and loading a
slide-in camper, check the
manufacturer's instructions.

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
13337620) - 2020 - CTC - 1/27/20
Driving and Operating 203
When carrying a slide-in
camper, the total cargo load of
the vehicle is the weight of the
camper plus:
.Everything added to the
camper after it left the
factory.
.Everything in the camper.
.All the people inside.
The CWR is the maximum
weight of the load the vehicle
can carry. It does not include the
weight of the people inside. But,
use about 68 kg (150 lb) for
each seat.
The total cargo load must not be
more than the 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
floor for measurement purposes.
The recommended location for
the cargo center of gravity is in
zone 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.
Here is an example of proper
truck and camper match:
1.Camper Center of
Gravity
2.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
figure, the weight of installed
additional camper equipment not
included in the manufacturer's
camper weight figure, the weight
of camper cargo, and the weight
of passengers in the camper.
The total cargo load should not

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
13337620) - 2020 - CTC - 1/27/20
204 Driving and Operating
exceed the truck's cargo weight
rating, and the camper's center
of gravity (1) should fall within
the truck's recommended center
of gravity zone (2) when
installed.
Any accessories or other
equipment that are added to the
vehicle must be weighed. Then,
subtract this extra weight from
the CWR. This extra weight may
shorten the center of gravity
zone of the vehicle.
If the slide-in camper and its
load weighs less than the CWR,
the center of gravity zone for the
vehicle may be larger.
Secure loose items to prevent
weight shifts that could affect the
balance of the vehicle. When the
truck-camper is loaded, drive to
a scale and weigh on the front
and on the rear wheels
separately to determine axle
loads. Individual axle loads
should not exceed either of thegross axle weight ratings
(GAWR). The total axle
loads should not exceed the
vehicle's gross vehicle weight
rating (GVWR). These ratings
are given on the Certification/
Tire label attached to the
B-pillar. See
“Certification/Tire
Label” underVehicle Load
Limits 0197. If weight ratings
are exceeded, move or remove
items to bring all weights below
the ratings.
See your dealer for more
information on curb weights,
cargo weights, Cargo Weight
Rating, and the correct center of
gravity zone.Starting and

New Vehicle Break-In
Caution
The vehicle does not need an
elaborate break-in. But it will
perform better in the long run if
you follow these guidelines:
. Keep the vehicle speed at
88 km/h (55 mph) or less for
the first 805 km (500 mi).
. Do not drive at any one
constant speed, fast or slow,
for the first 805 km (500 mi).
Do not make full-throttle
