To determine the available towing capacity, use
the following procedure.
1. Find the GCWR for your vehicle on the
ЉTowing Load/SpecificationЉ chart found
later in this section.
2. Subtract the actual vehicle weight from the
GCWR. The remaining amount is the avail-
able maximum towing capacity.
To determine the Gross Trailer Weight, weigh
your trailer on a scale with all equipment and
cargo, that are normally in the trailer when it is
towed. Make sure the Gross Trailer Weight is not
more than the GrossTrailer Weight Rating shown
on the trailer and is not more than the calculated
available maximum towing capacity.
Also weigh the front and rear axles on the scale to
make sure the Front Gross Axle Weight and Rear
Gross Axle Weight are not more than Front
Gross Axle Weight and Rear Gross Axle Weight
on the F.M.V.S.S./C.M.V.S.S. certification label.
The cargo in the trailer and vehicle may need to
be moved or removed to meet the specified rat-
ings.
Example:
● Gross Vehicle Weight (GVW) as weighed
on a scale- including passengers, cargo and
hitch - 5,185 lb. (2352 kg).
● Gross Vehicle Weight Rating (GVWR) from
F.M.V.S.S./C.M.V.S.S. certification label -
5,815 lb. (2638 kg).
● Gross Combined Weight Rating (GCWR)
from “Towing Load/SpecificationЉ chart -
11,133 lb. (5050 kg).
● Maximum Trailer towing capacity from “Tow-
ing Load/SpecificationЉ chart - 6,100 lb.
(2767 kg).
5,815 lb. (2638 kg) GVWR
– 5,185 lb. (2352 kg) GVW
= 630 lb. (286 kg) Available for tongue
weight
11,133 lb. (5050 kg) GCWR
– 5,185 lb. (2352 kg) GVW
= 5,948 lb. (2698 kg) Capacity available for
towing
630 lb. (286 kg) Available tongue weight
/ 5,948 lb. (2698 kg) Available capacity
= 10 % tongue weight
The available towing capacity may be less than
the maximum towing capacity due to the passen-
ger and cargo load in the vehicle.
Remember to keep trailer tongue weight be-
tween 10 - 15% ofthe trailer weight. If the tongue
load becomes excessive, rearrange the cargo to
obtain the proper tongue load. Do not exceed the
10 - 15% tongue weight specification even if the
calculated available tongue weight is greater
than 15%. If the calculated tongue weight is less
than 10% , reduce the total trailer weight to
match the available tongue weight.
Always verify that available capacities are within
the required ratings.
Trailer frontal area
CAUTION
Exceeding the maximum trailer frontal
area specification may exceed the towing
capacity of the vehicle. This may affect the
towing performance and lead to vehicle
damage.
The trailer frontal area affects the towing load of a
trailer. The frontal area is the total area of the
vehicle and trailer that is affected by air resis-
tance while towing. Do not exceed the maximum
trailer frontal area specification shown in the
ЉTowing Load/Specification” chart. The frontal
area can be determined by multiplying the width
of the trailer by the height of the trailer. For
example, a trailer that is 8 feet wide by 6 feet tall
has a trailer frontal area of 48 square feet.
