includes 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
aweighstation.Yourdealercan
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. SeeAdding a Snow
Plow or Similar
Equipment0345.
{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

264 Driving and Operating
There is also important loading
information for off-road driving in
this manual. See“Loading the
Vehicle for Off-Road Driving“
underOff-Road Driving0251.
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,
alimitonhowmanypeople
carried inside the vehicle may
be necessary. Be sure to weigh
the vehicle before buying and
installing the new equipment.
Caution
Overloading the vehicle may
cause damage. Repairs would not
be covered by the vehicle
warranty. Do not overload the
vehicle.
Remember not to exceed the
Gross Axle Weight

266 Driving and Operating
Use the rear edge of the load
floor 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.
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
aslide-incamper,thetotalcargo
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
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
ascaleandweighonthefront
and on the rear wheels
separately to determine axle
loads. Individual axle loads
should not exceed either of the
gross axle weight ratings
(GAWR). The total axle loads

Accessory Power Outlets (APOs)
The vehicle may have AccessoryPower Outlets (APOs) in severallocations. SeePower Outlets0124.
The APOs in the console or centerseat position are powered byRetained Accessory Power (RAP).They will continue to work for up to10 minutes after the key is turnedfrom ON/RUN to LOCK/OFF, or untilthe driver door is opened.
The APOs on the center stack comefrom the factory powered directlyfrom the vehicle battery, and supplyaccessory power at all times,regardless of ignition key position.
If electronic items are left pluggedinto these APOs for long periods oftime with the vehicle off, the vehiclebattery could be drained. Thevehicle may not start if the battery isallowed to drain for an extendedperiod of time.
Engine Coolant Heater
The engine heater can provideeasier starting and better fueleconomy during engine warm-up incold weather conditions at or below✓18 °C (0 °F). Vehicles with anengine heater should be plugged inat least four hours before starting.An internal thermostat in theplug-end of the cord may exist,which will prevent engine coolantheater operation at temperaturesabove✓18 °C (0 °F).
If the vehicle has a diesel engine,see the Duramax dieselsupplement.
