Certification/Tire Label
A vehicle-specific Certification/Tire 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 GVWR 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 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 0 303.
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.
Driving and Operating
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.
