2006 Nissan Towing Guide 1
INTRODUCTION

SAFETY IS PRIORITY ONE
Obviously, your first concern should be safety. Your vehicle was designed to be used
primarily to carry passengers and cargo. Always remember that towing a trailer places
additional loads on your vehicle’s engine, drivetrain, steering, braking, and other systems.
Therefore, be certain that your vehicle can meet the demands of the towing application you
have in mind.
Rent or purchase only the highest-quality towing and safety equipment you can find.
Reinforced tow hitches designed especially for certain Nissan vehicles are available from
your Nissan dealer.* Hitches for the other Nissan models should be bought from and
installed by a professional supplier of towing equipment. Finally, it is important to follow the
towing capacity limit set for your specific vehicle, and to ensure that your vehicle is in top
mechanical condition; especially the tires, brakes, suspension, and engine cooling system.
See your owner’s manual for details.

NEVER EXCEED THE ESTABLISHED TOWING CAPACITY
Towing capacities vary from vehicle to vehicle. See the SPECIFICATIONS section of this
guide to view the towing capacities of 2006 Nissan vehicles produced at the time of
Towing Guide publication. Use this data to help select the proper Nissan vehicle to meet
your anticipated needs, and refer to it when renting a trailer or other piece of towing
equipment.

EQUIP YOUR NISSAN FOR TOWING
The frequency and type of towing should also influence the manner in which you equip
your vehicle. If you plan to tow often, either for recreation or work, select the engine size,
transmission type, suspension, and towing capacity that are best suited to your
requirements. This guide can help you select that equipment.
If, on the other hand, your towing will be infrequent, choose the Nissan vehicle and
equipment that best meets your day-to-day needs. Then, be careful not to exceed the
towing capacity on those few occasions when you do tow.


READ THIS GUIDE BEFORE YOU TOW
This guide was designed to provide an overview of safe towing practices. In it you’ll find
information on towing equipment, safety, proper loading and driving techniques, towing tips,
and much more.
It is also a good idea to discuss your towing requirements with either your Nissan dealer
or a professional supplier of towing equipment before you equip your Nissan vehicle for
towing. Finally, there are state and local laws on towing that you should review to ensure
you comply with all regulations.

TOWING
EQUIPMENT

RENTING
The first thing to keep in mind when renting a trailer is to rent only from professional
companies that specialize in towing and towing equipment. More than likely, these
representatives will have some experience in selecting and fitting the towing equipment
that is appropriate for your Nissan vehicle.
When renting, make sure you have your owner’s manual on hand so that you can check
the towing capacities for your specific vehicle. Never rent a trailer that exceeds these
capacities, and make sure that any other equipment you rent is sufficient for your loaded
trailer.
While you’re there, ask questions: How much does the trailer weigh? What is the trailer
tongue load? How much weight will the trailer hold? What type of brakes is it equipped
with? All of these items have an effect on whether your Nissan vehicle is capable of safely
pulling that trailer or piece of equipment.
Make certain that all trailer stoplights, taillights, and turn signals are hooked up and
operate correctly, and that all safety equipment is properly installed. Check the safety
chains/cables, tie-downs, etc.
Carefully inspect the condition of the trailer and equipment. Are the tires worn
excessively? Are the tire pressures correct? Are there broken welds, missing bolts or
pieces? All these factors can also affect your safety.
Towing safety should be a high priority when choosing and renting equipment, and this
is especially true concerning hitches. Never rent a clamp-on-type hitch. Since Nissan
bumpers not specifically marked for towing are not designed for trailer loads, using this
type of hitch may cause damage to your vehicle and could result in trailer separation during
towing. Tow only with a permanent-type hitch.

PURCHASING
Purchase towing items such as hitches and hitch balls only from your Nissan dealer or a
professional supplier of towing equipment.
If you are intending to use your vehicle to tow a trailer you already own, first determine
the trailer’s weight when fully loaded. This will tell you if, in fact, your vehicle is capable of
pulling this amount of weight. In addition, it will also help you purchase the right type, style,
and class* of hitch and other equipment.

*See the SPECIFICATIONS section of this guide for equipment class information specific to your
vehicle.

2006 Nissan Towing Guide 8 BREAKAWAY SWITCH
On a trailer with electric brakes, a breakaway switch can automatically activate the trailer
brake system if the trailer becomes separated from the tow vehicle. Should the trailer
become detached, a breakaway switch may help prevent the trailer from wandering into
another lane and will bring it to a safer stop with less damage.
A breakaway switch relies on the power of a trailer battery, so make sure it is not
discharged. Never use the breakaway switch to “park” the trailer on a grade. The battery
would eventually discharge and release the brake, allowing the trailer to roll.
Be sure to leave enough slack in the tether on the breakaway switch to turn corners
without binding. If not, the electric trailer brakes will lock-up and not release.
See your trailer manufacturer for proper installation of a breakaway switch that is
compatible with your trailer braking system.

TRAILER LIGHTS
Trailer lights should comply with all applicable federal, state, and local regulations, and
should be in proper working order at all times. A trailer’s taillights, stoplights, and turn
signals must be wired* into the tow vehicle’s electrical system. Many trailers use the same
filament of a dual-filament bulb for both stoplights and turn signals. The second filament is
used for the trailer’s taillights. All Nissan vehicles utilize separate filaments for each
function. Direct splicing of this type of trailer lighting may cause damage to your vehicle’s
electrical system and malfunction of the trailer lighting. When connecting your Nissan
vehicle to this type of trailer lighting system, a 3-wire to 2-wire power converter** must be
used. A power converter of this type creates only minimal additional demand (draw) on the
vehicle lighting circuits to power the trailer lighting.
Always check for correct operation of the turn signals, stoplights, and taillights every
time you connect a trailer for towing. Never replace vehicle fuses with fuses of a higher
amperage rating than the original.
NOTE – Improper or poor quality trailer harness wiring may affect your vehicle’s electrical
system. Use only a Nissan approved wiring harness, or consult your dealer or a
professional supplier of towing equipment for compatible equipment.



*See the SPECIFICATIONS section of this guide for wiring harness information specific to your
vehicle.
**Armada, Frontier, Pathfinder, Titan, and Xterra vehicles are pre-wired for trailer lighting and do not

require a converter.

2006 Nissan Towing Guide 9 BRAKES
As with hitches, there are several types of braking systems available. Most states require a
separate braking system on trailers with a loaded weight above a specific amount, so
check to ensure you comply with all regulations.

NOTE – Never connect a hydraulic trailer brake system directly to the vehicle
hydraulic brake system.

Surge Brakes – The surge brake is mounted on the trailer tongue with a hydraulic line
running to each trailer wheel. Surge brakes are activated by the trailer pushing against the
hitch when the tow vehicle is braking. Hydraulic surge brakes are common on rental trailers
and some boat trailers. In this type of system, there is no hydraulic or electric connection
for brake operation between the tow vehicle and the trailer.

Electric Trailer Brakes – Electric braking systems are activated by an electronic signal
sent from a trailer brake controller (special brake-sensing module).
If electric trailer brakes are used, Nissan recommends all-electronic actuation because
with this system it will not be necessary to tap into the tow vehicle’s hydraulic system.
For your convenience, Armada, Frontier, Pathfinder, Titan, and Xterra vehicles are pre-
wired to accommodate most popular electric trailer brake controllers. A wiring harness* is
either included with your vehicle or available from your Nissan dealer. This harness
provides electric trailer brake controller input and output connections to the vehicle wiring.
See a professional supplier of towing equipment for electric trailer brake controller
availability.
NOTE – Improper or poor quality trailer harness wiring may affect your vehicle’s electrical
system. Use only a Nissan approved wiring harness, or consult your dealer or a
professional supplier of towing equipment for compatible equipment.

for your Nissan vehicle.


*See the SPECIFICATIONS section of this guide for wiring harness information specific to your
vehicle.

2006 Nissan Towing Guide 14 TIRE PRESSURE
When towing a trailer, increase tow vehicle tire pressures to the recommended cold
specifications. You’ll find these figures in the owner’s manual and on the tire pressure chart
located in the vehicle. Trailer tire condition, size, load rating, and inflation pressure should
be in accordance with the trailer and tire manufacturer’s specifications.


TOWING
SAFETY

Towing can dramatically alter the handling and performance characteristics of your vehicle.
Plus, it puts increased strain on the engine and drivetrain. Therefore, it is always a good
idea to approach towing from the standpoint of safety — whether you’re purchasing
equipment or actually pulling the trailer.
Always make sure your vehicle’s towing capacity is adequate for the trailer you intend to
tow. Buy or lease only quality equipment, and have it installed only by professionals.
In addition, be certain that you have all of the equipment needed for safe towing,
including safety chains/cables, electric trailer brakes, electric trailer brake controller,
breakaway switch, extended rear view mirrors, and so on. All of these items have been
discussed in a previous section of this guide.
With regard to vehicle maintenance, you should follow a more frequent schedule, and
check fluid levels, pressures, tire condition, etc., more often when on the road. See your
owner’s manual for details.

LOADING YOUR TRAILER
Taking the time to load and balance your trailer properly will improve overall handling and
minimize the strain on your tow vehicle. Incorrectly loaded trailers tend to sway or swing
from side to side, upsetting vehicle handling. Careful loading and balancing can help
eliminate these problems.
As mentioned earlier, conventional trailer tongue load should fall between 10-15% of
the total trailer weight, and king pin load — if using a 5th wheel or gooseneck trailer —
should be between 15-25% of the total trailer weight. Excessive tongue/king pin load can
actually push the vehicle down in back, lifting the front wheels to a point where traction,
steering response, and braking are severely reduced. Insufficient tongue/king pin load can
cause instability, which may lead to “tail wagging” or jackknifing.

2006 Nissan Towing Guide 16 VEHICLE SPEED
Some states have specific regulations and speed limits for vehicles that are towing trailers.
Always obey these ordinances. Remember to reduce your speed in unsafe or less-than-
ideal road conditions or weather. When towing a trailer, braking distances increase while
handling agility decreases. Always leave yourself an extra margin of distance to respond to
emergency situations.

PASSENGERS
Never allow passengers to ride inside a trailer while it is being towed. Not only is this
unlawful in most areas, passengers could be seriously injured during sudden trailer
movement or in an accident. In addition, trailers may allow fumes from the tow vehicle to
leak inside. This could result in carbon monoxide poisoning from the engine exhaust.

VEHICLE MODIFICATIONS
Vehicle modifications — beyond those required for proper hitch installation, wiring hook-up,
and necessary cooling system upgrading — are not recommended for any Nissan vehicle
being used for towing purposes. Changes to the drivetrain, suspension, exhaust systems,
frame structure/unibody, or other vehicle components are not necessary for towing within
the limits described in this guide. These changes may diminish the reliability and longevity
of your vehicle and possibly void warranty coverage as well.

TOOL KIT
It is always a good idea to travel with a special tool kit when towing. In addition to tools, it
should contain flares, a flashlight, emergency reflectors, jumper cables, extra fuses, extra
radiator coolant, oil, and easily replaced spare parts such as taillight bulbs. You should also
carry spare tires for your tow vehicle and trailer, as well as a jack suitable for use on the
trailer. Be aware that not all automotive jacks can be used safely on a trailer.

BEFORE STARTING OUT
Before starting out on a trip, make one last inspection of the tow vehicle and the trailer. Are
the tire pressures correct? Are the safety chains/cables securely in place? Is the cargo tied
down securely? Do all the lights work? Is the coupler properly attached over the hitch ball
and secured using a locking pin? Is the breakaway switch hooked up and functioning
properly? Are vehicle and electric trailer brakes working properly?
Make a checklist of key items to be inspected, and don’t forget the basics. When
towing, vehicle engine oil, transmission oil, and coolant should always be checked before
starting out. Finding a potential problem while in your driveway is better than discovering it
miles from home.

TOWING
TIPS

If you’ve never towed a trailer before, be aware that it does take getting used to. To begin
with, towing noticeably affects your vehicle’s performance:
Š It will not accelerate as quickly — an important point to keep in mind when merging onto
a highway.
Š It will not stop as quickly. Leave more room than usual between you and the traffic
ahead, and brake sooner when coming to a stop.
Š Abrupt maneuvering can unbalance the load and reduce the handling stability of your
tow vehicle. Plan ahead and make lane changes and turns smoothly.
If possible, before you actually hit the open road, practice towing in a large, uncrowded
area such as a stadium or shopping center parking lot. Become especially familiar with
backing up a trailer — the maneuver many people find most difficult.

REDUCE SPEED
Drive your vehicle at a moderate speed, and remember to reduce your speed in unsafe or
less-than-ideal road conditions or weather. The tendency for a trailer to sway increases
with speed, and such swaying can result in a loss of control.

BRAKE SOONER
The combination of your tow vehicle and trailer obviously requires a greater distance to
stop. A good rule of thumb to remember is that for each 10 mph of speed, allow yourself
one tow vehicle and trailer length of distance between the front of your vehicle and the
vehicle ahead.
When braking, use firm but gradual pressure on the pedal rather than panic braking.
Applying the brakes abruptly or with too much force can cause the trailer to skid or
jackknife at its point of attachment with the vehicle. This, in turn, can throw the tow vehicle
out of control.
If equipped with an electric trailer brake controller, follow the recommended operational
instructions.

PASS CAREFULLY
As mentioned in the introduction to this section, because of the added weight of the trailer,
acceleration capability is reduced and you’ll require a longer distance to pass another
vehicle. Be certain you have sufficient time and space to pass safely. Obviously, never
attempt passing on hills or when going around curves.

2006 Nissan Towing Guide 18 CORNER MORE SLOWLY
Know your vehicle and trailer capabilities. Entering a sharp corner too quickly or abruptly
can “crack the whip,” whereby the trailer can actually pull the tow vehicle off the road.
Therefore, when approaching a relatively sharp corner, begin braking sooner than you
would when not towing. Do your braking in a straight line prior to the corner, and turn
smoothly into it. In addition, remember to make a wider turn than normal to ensure that the
trailer safely clears the inside of the turn.
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. 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; however, there is a “trick” that can simplify
the procedure considerably. Simply steer with one hand at the bottom of the steering
wheel. To turn the trailer to the left, first move 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:
Š Have someone block the wheels once the tow vehicle and trailer are in position and
being held by the vehicle’s brake.
Š Next, apply the parking brake, and only then move the gear lever into PARK. If you move
the lever into PARK before blocking the wheels and applying the parking brake,
transmission damage may 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’s a good idea to allow more time than
usual due to the engine’s reduced performance.

2006 Nissan Towing Guide 19 AUTOMATIC CRUISE CONTROL
Do not use cruise control while towing a trailer.

TOW MODE (IF EQUIPPED)
Tow Mode should be used when the vehicle and trailer weight is at least 75% of the
vehicle GCWR. This mode is most useful when towing a heavy trailer or hauling a heavy
load, particularly when stop-and-go traffic, rolling terrain, or a busy parking lot is involved.
Driving the vehicle in Tow Mode with minimal trailer load will not cause any damage;
however, fuel economy may be reduced, and transmission/engine driving characteristics
may feel different.

HILLS – UPGRADES
As the incline increases, shift down to a lower gear to maintain speed and prevent the
engine from lugging. However, for long and steep grades, do not stay in first gear when
driving above 35 mph or in second gear above 58 mph.* 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) very
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
While going downhill, the weight of the trailer pushing on the tow vehicle may decrease
overall stability. Therefore, to maintain adequate control, reduce your speed and shift
to a lower gear.
When descending a hill, also avoid long or repeated use of the brakes 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.

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, or 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:

1. Pull your vehicle safely over to the side of the road, out of traffic. Apply the parking
brake, and move the gearshift lever to NEUTRAL (manual) or PARK (automatic). DO
NOT STOP THE ENGINE.

*For Murano, see your owner’s manual for information applicable to your vehicle.
**See your owner’s manual for additional indications that your vehicle may be overheating.
