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 FX and QX vehicles are available from your Infiniti dealer. Hitches for
the other Infiniti 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 or refer
to your owner’s manual for detailed information regarding the towing capacity of your specific
vehicle. Use this data to help select the proper Infiniti vehicle to meet your anticipated needs, and
refer to it when renting a trailer or other piece of towing equipment.
EQUIP YOUR INFINITI 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 Infiniti 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 Infiniti dealer or
professional supplier of towing equipment before you equip your Infiniti 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 Infiniti 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 Infiniti 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, tiedowns, 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 Infiniti bumpers 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 Infiniti dealer or 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.
If you are buying a travel or boat trailer, be sure that your Infiniti vehicle has the towing capacity to
pull it. See the SPECIFICATIONS section of this guide or refer to your vehicle owner’s manual for
detailed information regarding the towing capacity of your specific vehicle. Your owner’s manual
should ALWAYS be referenced before making any towing decisions.
Naturally, you’ll want to buy the highest-quality equipment you can find for maximum towing safety.
And if you plan to tow often, consider convenience. Quick-disconnect trailer light connectors and
ratchet-type tie-downs, for example, make the job go faster and easier, and are usually worth the
small extra investment.
*See the SPECIFICATIONS section of this guide for equipment class information specific to your vehicle.

WHAT’S RIGHT FOR YOU
TYPES OF EQUIPMENT
Towing requires a variety of equipment, and, depending upon the application, there can be several
types or styles of each piece of equipment. Working with your Infiniti dealer or professional supplier
of towing equipment, it should be relatively simple to determine the proper type of equipment for
your specific vehicle given the intended application. This section explains the most common pieces
of towing equipment available.
HITCHES
Whichever type of hitch you use, it should be firmly bolted to your vehicle, and should be of the
appropriate weight class for the equipment you intend to tow. In addition, keep the following in
mind:
Do not modify the vehicle’s braking or exhaust systems or its body structure/frame when
installing the hitch.
Be sure that the hitch does not interfere in any way with the vehicle’s energy-absorbing bumper.
Regularly check to see that all hitch-mounting bolts are securely fastened.
Where practical, remove the hitch when not in use. Your Infiniti dealer can assist you in hitch
removal and reinstallation. When removed, seal the bolt holes to prevent road spray, fumes,
water, and dirt from entering the vehicle.
For receiver-type hitches using a ball mount, the ball mount should be removed when not towing.
If you install a hitch yourself, remember that it must be securely attached to the frame or
underbody, according to the manufacturer’s instructions. Never attach a hitch or towing device
to the vehicle axle housing. This may damage the housing, wheel bearings, wheels, or tires.
Hitch Types
Bumper Hitch – This is a special reinforced
bumper designed to accommodate a hitch
ball.
2006 Infiniti Towing Guide

Page 5
Receiver Hitch – A receiver hitch is
bolted directly to the vehicle structure for added
strength and durability. Infiniti bolt-on receiver
hitches are designed specifically for Infiniti vehicles
and include the necessary reinforcements, with
ample clearance around bumpers, frame members,
etc. These hitches allow for the removal of the ball
mount when not towing.
Clamp-On Bumper Hitch – As the name suggests,
this type of temporary hitch clamps onto the bumper
assembly. Infiniti does not recommend the use of
this type hitch for a number of reasons. It may
interfere with performance of the energy-absorbing
bumper. And because the bumper was not designed
to carry this type of load, it could damage the
bumper and bodywork, and may possibly result in
trailer separation during towing. Therefore, tow only
with a permanent hitch.
Weight-Distributing Hitch System – This type of
system uses a “load-leveling” or “equalizing”
hitch. The weight-distributing feature helps shift
the trailer tongue weight to all trailer tires and the
tow vehicle front tires.
Purchase of a Weight-Distributing hitch ball mount
(Class IV) is STRONGLY RECOMMENDED if you own
a QX vehicle and plan to tow trailers with
maximum weight over 5,000 lbs. This ball mount
includes a
for use with the optional tow package.

BALL MOUNT
A ball mount (also known as a drawbar or “stinger”) is a bar that holds a hitch ball and is inserted
into a receiver-type hitch. Ball mounts come in a number of weight capacities (3,500 lbs., 5,000 lbs.,
etc.) and sizes (1
1
/4”, 2”, etc.), and can
be weight-distributing or non-weight-
distributing.
HITCH BALL
A hitch ball is bolted through a ball
mount or a hitch hole in the tow vehicle’s
rear bumper. The coupler on the trailer
tongue attaches over the hitch ball.
Like ball mounts, hitch balls come in
different weight capacities and sizes.
Therefore, always make sure the hitch ball selected has the proper shank diameter and weight
rating for the ball mount as well as the coupler on your trailer. Using a 1
coupler, for example, could result in the trailer separating from the tow vehicle.
There are different diameters of hitch holes. If a hitch ball with a smaller shank is used in a larger
hole, a bushing should be used to take up the excess clearance. Bushings are often included with
Infiniti accessory hitch balls.
A simple maintenance routine for the hitch ball is recommended to keep it in top condition. Coating
it with light grease will minimize wear of both the coupler and hitch ball. Also, by removing the hitch
ball when not towing, or by protecting it with a special cover, you will help prevent rust from forming
on it.

TRAILER TONGUE
The tongue (see illustrations on page 6) is the part of the trailer that extends forward to meet the tow
vehicle, and also carries the coupler assembly. Knowledge of the trailer tongue load is critical, as it
can have a significant effect on the handling of the tow vehicle. See the SPECIFICATIONS section of
this guide or refer to your vehicle owner’s manual to view the maximum trailer tongue load listed for
your vehicle.

SAFETY CHAINS/CABLES
Always use suitable safety chains/cables between the tow vehicle and the trailer. If the hitch should
break or become disengaged for some reason, these chains/cables will provide an emergency
connection between the vehicle and the trailer.
Coupler
Trailer Tongue
OK
Not OK
The chains/cables should be crossed
under the trailer tongue and attached to
the hitch or vehicle frame. Crossing the
chains/cables under the tongue will help
prevent the tongue from hitting the
ground should the trailer become
disconnected. Also, be sure to leave
enough slack in the chains/cables to turn
corners without binding; however, note
that excessive slack will allow the
chains/cables to drag on the ground.
Do not use S-hooks for attaching, as they
may become un-hooked, and are illegal in
many states. To avoid damage to the
bumper and chains/cables when making
a sharp turn, do not attach the
chains/cables too close to the coupler.
Consult your trailer manufacturer for the proper location of the chain/cable attachment to the trailer.
REAR VIEW MIRRORS
In many cases, a trailer can block your rear vision when you’re using only the standard Infiniti rear
view mirrors. These mirrors were not designed for towing.
“Extended” mirrors specifically designed for trailer towing should be used when your rearward
vision is obstructed. Before using these mirrors, make certain that they comply with state and local
regulations. Telescoping Tow Mirrors are available as an accessory for QX vehicles. Contact your
Infiniti dealer for details.
2006 Infiniti Towing Guide

Page 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 you do 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 Infiniti
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 Infiniti 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 an Infiniti 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.
**QX vehicles are pre-wired for trailer lighting and do not require a converter.
2006 Infiniti Towing Guide

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, Infiniti 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, QX 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 Infiniti
dealer. This harness provides electric trailer brake controller input and output connections to the
vehicle wiring. See a professional supplier of towing equipment for trailer brake controller
availability.
NOTE – Improper or poor quality trailer harness wiring may affect your vehicle’s electrical system.
Use only an Infiniti approved wiring harness, or consult your dealer or professional supplier of
towing equipment for compatible equipment.

PREPARING YOUR VEHICLE
BREAK-IN AND MAINTENANCE SCHEDULE
Infiniti recommends that you allow a sufficient “break-in” (500 miles) of both the engine and
drivetrain before towing with your new Infiniti vehicle. In addition, for the first 500 miles that you
tow a trailer, do not drive over 50 mph and do not make starts at full throttle.
Keep in mind, too, that towing places higher demands and added loads on vehicle components, so
more frequent maintenance is called for. Your service maintenance guide provides the accelerated
maintenance schedule for towing purposes. Engine oil, filter, transmission oil, and possibly other
fluids should be changed more frequently when towing.
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.
MEASURING VEHICLE WEIGHT
The key to safe, efficient towing has to do with weight. Your vehicle — SUV 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:
Gross Vehicle Weight
Gross Axle Weight (Front and Rear)
Gross Combined Weight
Trailer Tongue Load
These ratings are based upon normal highway driving and may be reduced if operating in reduced-
traction situations, e.g., slippery boat ramps.
NOTE – Attempting to tow loads greater than the GVWR, GAWR, GCWR, and the trailer tongue 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.
2006 Infiniti Towing Guide

Page 11
GROSS VEHICLE WEIGHT (GVW)
The Gross Vehicle Weight (GVW) is the total weight of the vehicle, plus passengers, cargo, fuel,
hitch, trailer tongue weight, 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 weight to determine the approximate GVW.
The GVW you come up with must not exceed the Gross
Vehicle Weight Rating (GVWR) for your vehicle.
On all Infiniti vehicles, the GVWR is shown on the
Federal Motor Vehicle Safety Standard (F.M.V.S.S.)
certification label located in the driver’s-side door
area.
To avoid overloading the vehicle, be sure to include
the trailer tongue weight as a part of the cargo when
determining how much weight can be safely carried
inside the vehicle. The weight of the roof rack cargo
should also be included.
2006 Infiniti Towing Guide
10
Page 12
GROSS AXLE WEIGHT (GAW)
The Gross Axle Weight (GAW) is the maximum weight each axle (front and rear) is designed to safely
carry.
To determine the GAW, load the vehicle as you would for towing and attach the loaded trailer. At a
public scale, with the loaded trailer attached, place only the tow vehicle front wheels on the scale to
determine the actual front axle GAW. To obtain the rear axle GAW, place all four tow vehicle wheels
on the scale. From that figure, subtract the front GAW and you’ve got the rear GAW amount.
The GAW you come up with must not exceed the Gross Axle Weight Rating (GAWR) for your vehicle.
On Infiniti vehicles, the GAWR for both axles is listed on the F.M.V.S.S. certification label.
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. See the SPECIFICATIONS section of this guide or refer to your vehicle owner’s manual to
view the GCWR listed for your vehicle.
2006 Infiniti Towing Guide

Page 13
TRAILER TONGUE LOAD
Trailer tongue load is the amount of weight pressing down on the tow vehicle hitch. To measure
trailer tongue 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 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, keep the trailer tongue load between 10 – 15% of the actual trailer weight,
within the limits of the maximum trailer tongue load allowable. For example, to determine the proper
trailer tongue load for a 1,500-lb. trailer, multiply the weight of 1,500 lbs. by 10% to arrive at a figure
of 150 lbs. See the SPECIFICATIONS section of this guide or refer to your vehicle owner’s manual to
view the maximum trailer tongue load listed for your vehicle.
NOTE – Trailer tongue load must be more than 10% but not over 15% of the total trailer weight.
HITCH AND TRAILER HEIGHT
It is important that your trailer floor
and tongue ride as level as possible.
This will help prevent over-angling,
bottoming-out, and improper load
transfer. Therefore, the hitch or
trailer tongue should be adjusted
during the initial vehicle/trailer fit-up
to ensure a level ride. Ball mounts
are available in different
configurations to adjust the ball
height.
2006 Infiniti Towing Guide

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.
We’ve already talked about trailer tongue load. It should fall between 10 – 15% of the total trailer
weight. Excessive trailer tongue 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
trailer tongue load can cause instability, which
may lead to “tail wagging” or jackknifing.
With this in mind, proper loading is extremely
important. When loading a trailer, 60% of the
total cargo weight should be positioned in the
front portion of the trailer and 40% in the back.
Then the load should be adjusted until the
proper tongue-load ratio is achieved.
2006 Infiniti Towing Guide
13
Page 15
The trailer load should be balanced equally
from side-to-side. Unequal side-to-side
loading can negatively affect handling and
braking. Once in place, all cargo should be
firmly secured to prevent shifting. If the load
should shift abruptly during braking or
cornering, it could quickly affect the handling
of your vehicle and cause a very unsafe
situation.
Finally, do not carry flammable materials, such as gasoline, in your trailer. In the event of an
accident, an explosion or fire could occur.
ENSURING VEHICLE/TRAILER STABILITY
Improper loading, excessive or insufficient trailer tongue load, overloading, excessive trailer weight,
poorly designed trailer suspensions, crosswinds, and poor maintenance are all things that can
affect the stability of your vehicle/trailer combination.
If swaying does occur, check the cargo load for proper balance and distribution to ensure proper
trailer tongue load. In addition, check the condition of the suspension and shocks, as well as the
tires, tire pressures, and wheel bearings on both the tow vehicle and trailer. If swaying occurs
because of high winds or poor weather conditions, wait until these conditions improve before
resuming your trip.
Finally, if the swaying continues and you feel your trailer is suitably balanced and within the towing
capacity limits of your vehicle, discontinue towing and consult your Infiniti dealer or trailer
manufacturer to determine the problem. Most important, do not tow until the problem is corrected.
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.
2006 Infiniti Towing Guide
14
Page 16
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 Infiniti 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.
2006 Infiniti Towing Guide

Page 17
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:
It will not accelerate as quickly — an important point to keep in mind when merging onto a
highway.
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.
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.
CORNER MORE SLOWLY
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.
2006 Infiniti Towing Guide
16
Page 18
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:
Have someone block the wheels once the tow vehicle and trailer are in position and being held
by the vehicle’s brake.
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.
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 Infiniti Towing Guide
17
Page 19
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.
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.
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.
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.

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.
2. Turn off the air conditioning and, after opening all the windows, turn the heater on to maximum
hot and the fan to its highest speed. The heater core in your vehicle is just like a miniature
engine radiator and will provide an extra cooling surface to help reduce engine temperature.
3. Run the engine at a fast idle (approximately 1,500 rpm) until the temperature gauge returns to a
normal reading. If the temperature does not drop or continues to increase, stop this step
immediately.
4. Being cautious of traffic, step out of the vehicle and, from a safe distance, look for steam
underneath the engine. If you see steam or leaking coolant, stand clear to avoid being burned.
Shut off your engine immediately and allow it to cool. If there is no steam, open the hood.
Never remove the radiator cap when the radiator is hot. If the cap is removed under these
conditions, hot water under high pressure may spurt out, possibly causing serious injury.
5. As soon as the engine has cooled to its normal operating temperature, visually inspect the
drive belts for damage or looseness. A loose belt reduces water pump efficiency. Be careful to
keep your hands, hair, jewelry, and clothing clear of the running drive belt and other moving
parts when inspecting the engine and radiator. Also check to see if the cooling fan is running,
and inspect the water pump, radiator, and radiator hoses for leaks. Keep in mind, too, that if
your vehicle is equipped with an electric fan motor, it may start without warning any time the
coolant temperature is high. If you find leaking coolant, a loose or missing drive belt, or an
inoperable fan, turn the engine off immediately.
6. If no leaks are apparent and all other components appear to be operating properly with the
engine cooled to its normal operating temperature, check the coolant level in the reservoir tank
with the engine running. Add coolant to the reservoir tank if needed. At this point, if repairs are
required, go to the nearest Infiniti dealer. Also, please see the IN CASE OF EMERGENCY section
of your owner’s manual for additional information on overheating.
NOTE – QX vehicles have an engine protection mode which helps reduce the chance of engine
damage if the engine coolant reaches a specified temperature. See your owner’s manual for details.
*See your owner’s manual for additional indications that your vehicle may be overheating.

brakes if it should accidentally become separated from the tow vehicle. A
breakaway switch may be used with both electric or surge trailer brake systems.
A reinforced bumper designed to accommodate a hitch ball.
A device that controls the 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.
