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:
 Gross Vehicle Weight
 Gross Axle Weight (Front and Rear)
 Gross Combined Weight
 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).
WARNING – Attempting to tow loads greater than the GVWR, GAWR, GCWR,
overloading and/or improperly loading the trailer tongue/king pin load specified could
adversely affect vehicle handling, braking, and performance. This may cause unsafe vehicle
handling and longer braking distance which could result in a serious accident and personal
injury. Failures to your vehicle caused by overloading are not covered by your vehicle’s
warranty.











GROSS VEHICLE WEIGHT (GVW)
The Gross Vehicle Weight (GVW) is the actual weight of the fully loaded vehicle or trailer,
including 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. That figure must include the combined weight of all
passengers and cargo that are normally in the vehicle when towing a trailer.
The GVW you come up with must not exceed the Gross Vehicle Weight Rating (GVWR)
for your vehicle.

2015 NISSAN Towing Guide 13










GROSS COMBINED WEIGHT (GCW)
The Gross Combined Weight (GCW) is the total weight of the tow vehicle with all
passengers, cargo, and fuel, plus the total weight of the trailer and all its cargo.
To determine the GCW, simply weigh your vehicle when fully loaded and ready to tow, and
add in the weight of the loaded trailer.
The GCW you come up with must not exceed the Gross Combined Weight Rating
(GCWR) for your vehicle. Refer to your vehicle owner’s manual to view the maximum
GCWR specification listed for your vehicle.

TRAILER TONGUE/KING PIN LOAD
The amount of trailer’s weight pressing down on the tow vehicle hitch ball is called trailer
tongue load (conventional trailer) or king pin load (5th wheel and gooseneck trailers).
To measure trailer tongue/king pin load, place the tongue of the trailer on a scale when the
trailer is not attached to the
vehicle. A separate vehicle
jack — not the trailer jack —
should be used, as the
location of the trailer jack is
rearward of the trailer tongue
and will not give you an
accurate measurement of the
true tongue/king pin load.
Make sure the vehicle jack is
placed directly under the
trailer tongue coupler, and the tongue is set at the height/level of the tow vehicle hitch.
For proper handling, you must keep conventional trailer tongue load between 10-15% of
the actual trailer weight, within the limits of the maximum trailer tongue load allowable.

WARNING -When towing a 5th wheel or gooseneck trailer, do not make sharp turns while
driving or backing as the trailer may contact the vehicle and cause damage to both the trailer
and vehicle, or result in an accident leading to property damage or personal injury.
A special extended 5th wheel pin box or sliding hitch may be required to provide additional
trailer-to-truck clearance for tight maneuvering.

BACK UP WITH CAUTION
Backing up with a trailer is a difficult maneuver. The best way to steer is by placing one hand
at the bottom of the steering wheel to direct the trailer. The trailer will go in the same direction
your hand moves. If you want to turn the trailer to the left, you will turn the steering wheel to
the left. To turn the trailer to the right, move the wheel to the right. All movements of the wheel
should be done in small increments. Of course, backing up should be done only at very slow
speeds. For large trailers that obstruct your rearward vision, have someone outside the vehicle
act as a “spotter” to guide you along.

PARK SMART
A tow vehicle and trailer can be an unwieldy combination in a small area, so always try to park
where you will have a relatively easy time maneuvering. Once parked, always block the wheels
on both the tow vehicle and the trailer.
Parking on a slope is not recommended. If, however, you must park on a slope and your
vehicle is equipped with an automatic transmission, there are some precautions you should
take:
 Have someone block the wheels once the tow vehicle and trailer are in position and are
being held by the vehicle’s brake.
 Next, apply the parking brake and only then move the gear lever into PARK.

CAUTION - If you move the lever into PARK before blocking the wheels and applying the
parking brake, it may be difficult later to shift out of PARK. Transmission damage could also
occur.

HIGH-ALTITUDE PERFORMANCE
An engine will lose about 4% of its performance for every 1,000 feet above sea level that you
travel. If you will be towing in high altitudes, it is a good idea to allow more time than usual due
to the engine’s reduced performance.

TOW MODE (IF EQUIPPED)
Tow Mode is recommended when towing a heavy trailer or hauling a heavy load, in stop-and-
go traffic, rolling terrain, or a busy parking lot. Driving the vehicle in Tow Mode may affect fuel

2015 NISSAN Towing Guide 22 1 Maximum Trailer Weight values are calculated assuming a base vehicle with driver and any
options required to achieve the rating. Additional passengers, cargo and/or additional
optional equipment will add weight to the vehicle and reduce your vehicle’s maximum
towing capacity and trailer tongue load.

2 Use of a weight-distributing hitch system is re when towing over 5,000 lbs.

3 The Maximum Trailer Weight and Gross Combined Weight ratings for 5th wheel and
gooseneck trailer towing are the same as specified for conventional trailer towing.

4 Most states require a separate braking system on trailers with a loaded weight above a
specific amount. Check local regulations where you plan to tow. 7-pin connector trailer
wire harnesses are required for use with trailer brakes (available separately).

Other Recommendations and Information – Towing performance and speed are affected by
vehicle payload, tow weight, road grades, and weather conditions, including high
temperatures. See your vehicle owner’s manual for details.



TOWING
GLOSSARY
5TH WHEEL
HITCH Located just forward of the rear axle centerline, this hitch uses a king pin to
serve as the pivot point for the trailer.

BALL MOUNT A bar that holds the hitch ball and is inserted into the hitch receiver. Also
commonly called a drawbar.

BREAKAWAY SWITCH A safety device using a trailer battery that automatically applies the trailer’s
brakes if the trailer accidentally becomes separated from the tow vehicle.
A breakaway switch may be used with both electric or surge trailer brake
systems.

BUMPER HITCH A reinforced bumper designed to accommodate a hitch ball.

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
