2008 NISSAN ALTIMA Towing Guide

2008 Nissan Towing Guide 8 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 Nissan
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 Armada and Titan vehicles. Contact
your Nissan dealer for details.

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 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,

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

2008 Nissan Towing Guide 9 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.

BRAKES
As with hitches, several types of braking systems are available. Most states require a separate
braking system on trailers with a loaded weight above a specific amount, therefore you should
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, and Titan 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.

*Armada LE, Frontier, Pathfinder, and Titan vehicles are pre-wired for trailer lighting and do not require
a converter.

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

2008 Nissan Towing Guide 10 SWAY CONTROL DEVICE
Sudden maneuvers, wind gusts, and buffeting caused by other vehicles can affect trailer
handling. Sway control devices may be used to help control these affects. If you choose to
use one, contact a reputable trailer hitch supplier to make sure the sway control device will
work with the vehicle, hitch, trailer and the trailer’s brake system. Follow the instructions
provided by the manufacturer for installing and using the sway control device.

PREPARING
YOUR VEHICLE

BREAK-IN AND MAINTENANCE SCHEDULE
Nissan recommends that you allow a sufficient “break-in” (500 miles) of both the engine and
drivetrain before towing with your new Nissan 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 Nissan 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.

MEASURING VEHICLE WEIGHT
The key to safe, efficient towing has to do with weight. Your vehicle — SUV, truck, minivan, 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

2008 Nissan Towing Guide 11 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 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.

2008 Nissan Towing Guide 12 On all Nissan 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/king pin load 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.






















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 Nissan 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.

TRAILER TONGUE/KING PIN LOAD
The amount of weight pressing down on the tow vehicle hitch is called trailer tongue load
(conventional trailer) or king pin load (5th wheel or 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. For

2008 Nissan Towing Guide 14 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.
5th wheel and gooseneck trailer king pin load must be kept between 15-25% of the actual
trailer weight, within the limits of the king pin load allowable.
See the SPECIFICATIONS section of this guide or refer to your vehicle owner’s manual to
view the maximum conventional trailer tongue load listed for your vehicle.
NOTE – The vehicle weight ratings (GVWR, GAWR, GCWR, etc.) must not be
exceeded, regardless of trailer or hitch type.

HITCH & 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 must be adjusted during the
initial vehicle/trailer fit-up to ensure a
level ride. Ball mounts are available in
different configurations to
adjust the hitch ball height.

TIRE PRESSURE
When towing a trailer, increase tow vehicle tire pressures to the recommended cold
specifications. You will find these figures in the vehicle owner’s manual and on the tire
pressure chart located in the vehicle. Trailer tire condition, size, load rating, and inflation
pressure must 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.

2008 Nissan Towing Guide 15 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
vehicle 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 must fall between 10-15% of the
total trailer weight. King pin load — if using a 5th wheel or gooseneck trailer — must be
between 15-25% of the total trailer weight.
Excessive tongue/king pin load can actually
push down the vehicle 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.
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/king pin load ratio is achieved.
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
