{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).
This can cause systems to
break and change the way the
vehicle handles. This could
cause loss of control and a
crash. Overloading can also
reduce stopping distance,
damage the tires, and shorten
the life of the vehicle.
Tire and Loading InformationLabel
Label Example
Avehicle-specificTireand
Loading Information label is
attached to the B-pillar or on the
forward edge of the rear door.
The Tire and Loading
Information label shows the
number of occupant seating
positions (1), and the maximum
vehicle capacity weight (2) in
kilograms and pounds.
The Tire and Loading
Information label also shows the
size of the original equipment
tires (3) and the recommended
cold tire inflation pressures (4).
For more information on tires
and inflation seeTires0316
andTire Pressure0323.
There is also important loading
information on the vehicle
Certification/Tire label. It may
show the Gross Vehicle Weight
Rating (GVWR) and the Gross
Axle Weight Rating (GAWR) for
the front and rear axles. See
“Certification/Tire Label”later in
this section.
“Steps for Determining CorrectLoad 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.

Example 3
1. Vehicle Capacity Weight forExample 3 = 453 kg(1,000 lb)
2. Subtract Occupant Weight@91kg(200lb)◊5=453 kg (1,000 lb)
3. Available Cargo Weight =0kg (0lb)
Refer to the Tire and Loading
Information label for specific
information about the vehicle's
capacity weight and seating
positions. The combined weight
of the driver, passengers, and
cargo should never exceed the
vehicle's capacity weight.
Certification/Tire Label
Label Example
Avehicle-specificCertification/
Tire label is attached to the
B-pillar or on the forward edge
of the rear door. 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 may
also show the maximum weights
for the front and rear axles,
called Gross Axle Weight
Rating (GAWR). To find out 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.
{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.

Ask your dealer for traileringinformation or advice.
Weight of the Trailer Tongue
The tongue load (1) of any trailer isvery important because it is alsopart of the vehicle weight. TheGross Vehicle Weight (GVW)includes the curb weight of thevehicle, any cargo carried in it, andthe people who will be riding in thevehicle as well as trailer tongueweight. Vehicle options, equipment,passengers and cargo in the vehiclereduce the amount of tongue weightthe vehicle can carry, which will alsoreduce the trailer weight the vehiclecan tow.
Trailer tongue weight (1) should be10–15% of the loaded trailerweight (2) up to 408 kg (900 lb).
Trailer rating may be limited by thevehicle's ability to carry tongueweight. Tongue weight cannot cause
the vehicle to exceed theGVWR (Gross Vehicle WeightRating) or the RGAWR (Rear GrossAxle Weight Rating).
After loading the trailer, weigh thetrailer and then the tongue,separately, to see if the weights areproper. If they are not, adjustmentsmight be made by moving someitems around in the trailer.

Warning (Continued)
.Underinflated tires pose
the same danger as
overloaded tires. The
resulting crash could
cause serious injury.
Check all tires frequently
to maintain the
recommended pressure.
Tire pressure should be
checked when the tires
are cold.
.Overinflated tires are
more likely to be cut,
punctured, or broken by
asuddenimpact—such
as when hitting a pothole.
Keep tires at the
recommended pressure.
.Worn or old tires can
cause a crash. If the
tread is badly worn,
replace them.
(Continued)
Warning (Continued)
.Replace any tires that
have been damaged by
impacts with potholes,
curbs, etc.
.Improperly repaired tires
can cause a crash. Only
the dealer or an
authorized tire service
center should repair,
replace, dismount, and
mount the tires.
.Do not spin the tires in
excess of 56 km/h
(35 mph) on slippery
surfaces such as snow,
mud, ice, etc. Excessive
spinning may cause the
tires to explode.
