2016 NISSAN Towing Guide 11
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:
 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 result in 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.

2016 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.

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
economy and transmission/engine driving characteristics. See your vehicle owner’s manual for
additional information about Tow Mode.

HILLS – UPGRADES
As the incline increases, if your vehicle is equipped with an automatic transmission — it is
designed to select automatically the correct gear for the best towing comfort and
performance. To maintain speed or avoid up and down shifts, manually shift to a lower gear as
needed.

The added weight of a trailer places an increased load on the engine and cooling system, so
monitor your coolant temperature gauge and automatic transmission fluid temperature gauge
(if equipped) carefully. At the first sign of overheating, pull to the side of the road. See IF
YOUR ENGINE OVERHEATS later in this section for more information.

HILLS – DOWNGRADES

WARNING - While going downhill, the weight of the trailer pushing on the tow vehicle
may decrease overall stability, and may deteriorate overall handling characteristics, which
could result in an accident, property damage, serious injury or death. Therefore, to maintain
adequate control, reduce your speed and shift to a lower gear. If your vehicle is equipped with
Tow Mode, see your vehicle owner’s manual for information about the use of this function.
Avoid long or repeated use of the brakes when descending a hill, as this reduces their
effectiveness, and could cause overheating. Shifting to a lower gear instead provides “engine
braking” and reduces the need to brake as frequently.

AUTOMATIC CRUISE CONTROL
WARNING – In order to maintain a safe distance to the vehicle ahead to avoid the
possibility of accidents, property damage, serious injury or death, never use the Intelligent
Cruise control (ICC) system while towing a trailer or other vehicle. If the ICC sensor cannot
detect the reflector on the vehicle ahead, the system may not function properly.

IF YOUR ENGINE OVERHEATS
“A moderate increase in engine operating temperature is normal when towing a trailer.” If,
however, the coolant temperature gauge reading is abnormally high, if you are experiencing a
significant loss of power, or if you hear unusual engine noises,* the engine may be overheating
and you should immediately take the following steps:

2016 NISSAN Towing Guide 23


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 that 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
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.
