Towing a trailer places an additional load on your vehicle’s engine,

transmission, axle, brakes, tires and suspension. Inspect these

components carefully prior to and after any towing operation. Refer to

Transmission fluid temperature gauge in the Instrument Cluster

chapter for the transmission fluid temperature information.

To find the maximum trailer weight allowed for your vehicle, consult

your authorized dealer (or the RV and Trailer Towing Guide provided

by your authorized dealer).

To calculate your maximum trailer weight on your own:

1. Pick-up trucks: Take curb weight, hitch hardware and the driver’s

weight, then subtract them from the GCWR listed for your vehicle

series and drive axle ratio listed on the following table.

2. Chassis cabs and pick-up trucks with aftermarket equipment:

Weigh your vehicle at a certified scale and subtract this actual curb

weight, hitch hardware and the driver’s weight from the GCWR listed

for your vehicle series and drive axle ratio listed on the following

table.

The weight of all additional cargo and passengers must be subtracted

from the maximum trailer weight calculated above.

Further trailer/hitch restrictions and limitations exist depending on the

type of trailer and hitch used. This information follows the table listing

the maximum GCWRs.

For load specification terms found on the label and instructions on

calculating your vehicle’s load, refer to Vehicle loading - with and

without a trailer in this chapter when figuring the total weight of your

vehicle.

Note: Do not exceed the tire ratings specified on the Tire Label or

Safety Compliance Certification Label.

WARNING: Do not exceed the GVWR or the GAWR specified on

the certification label.

WARNING: Towing trailers beyond the maximum recommended

gross trailer weight exceeds the limit of the vehicle and could

result in engine damage, transmission damage, structural damage, loss

of vehicle control, vehicle rollover and personal injury.
