2010 Nissan Towing Guide 11 MEASURING VEHICLE WEIGHT
The key to safe, efficient towing has to do with weight. Your vehicle — SUV, crossover, truck
or passenger car — is capable of carrying and towing only a certain amount of weight. You
must compare your vehicle’s tow weight ratings with the combined weight of the vehicle,
trailer, and their contents. This will help ensure that the total weight does not exceed any of
your vehicle’s tow weight ratings.
There are four weights to consider when towing:
Š Gross Vehicle Weight
Š Gross Axle Weight (Front and Rear)
Š Gross Combined Weight
Š Trailer Tongue/King Pin Load
These ratings are based upon normal highway driving and may be reduced if operating in
reduced-traction situations, for example, slippery boat ramps.
NOTE – Attempting to tow loads greater than the GVWR, GAWR, GCWR, and/or the trailer
tongue/king pin load specified could adversely affect vehicle handling, braking, and
performance. Damage to your vehicle resulting from overloading may not be covered by your
vehicle warranty.
GROSS VEHICLE WEIGHT (GVW)
The Gross Vehicle Weight (GVW) is the total weight of the vehicle, plus passengers, cargo,
fuel, hitch, trailer tongue/king pin load, and any optional equipment.
The best way to determine the GVW is by having the vehicle — loaded and ready to
tow — weighed at a public scale. To that figure, add the combined weight of all passengers.
Then, add the trailer tongue/king pin load to determine the approximate GVW. The GVW you
come up with must not exceed the Gross Vehicle Weight Rating (GVWR) for your
vehicle.

ELECTRIC TRAILER
BRAKES When the brakes on a tow vehicle are applied, an electric current is sent to
an actuator which applies the trailer’s brakes.
ELECTRIC TRAILER
BRAKE CONTROLLER A device that controls the electric trailer brakes.
GOOSENECK HITCH Located just forward of the rear axle centerline, this hitch uses a ball to
serve as the pivot point for the trailer.
GROSS AXLE
WEIGHT RATING (GAWR)
The maximum amount of weight each vehicle axle (front and rear) is
designed to safely carry.
GROSS COMBINED
WEIGHT RATING (GCWR) The maximum allowable combined weight of the vehicle and trailer,
including passengers and all cargo.
GROSS VEHICLE
WEIGHT RATING (GVWR) The maximum allowable weight of the vehicle, including passengers, cargo,
fuel, hitch, trailer tongue load, and any optional equipment.
KING PIN
LOAD The amount of trailer (5th wheel or gooseneck) weight pressing down on
the tow vehicle hitch.
HITCH BALL
A ball that connects the trailer to the tow vehicle hitch and provides the
means by which the trailer pivots during cornering. Available in a number of
sizes and weight capacities, it must correspond to the trailer coupler size,
and have a sufficient capacity rating for the trailer being pulled.
RECEIVER HITCH A frame- or structure-mounted hitch with a receiver that allows removal of
the ball mount.
SAFETY CHAINS/CABLES Provides an emergency connection between the tow vehicle and the trailer,
should the trailer become disengaged for any reason.
SURGE BRAKES
Hydraulic-type braking system activated by inertia. As the tow vehicle
begins to brake, the trailer pushes against the hitch ball, consequently
activating the trailer brakes.
TRAILER TONGUE/COUPLER The part of the trailer that extends forward to meet the tow vehicle, and also
carries the coupler assembly.
TRAILER TONGUE
LOAD The amount of trailer (conventional) weight pressing down on the tow
vehicle hitch.
WEIGHT-DISTRIBUTING
HITCH SYSTEM Type of hitch system that helps shift the trailer tongue weight to all trailer
tires and the tow vehicle front tires. Strongly recommended when towing
trailers with a Maximum Trailer Weight greater than 5,000 lbs.
WIRING HARNESS
Provides an electrical connection linking the tow vehicle’s electrical system
to the trailer’s system.
