2007 NISSAN 350Z Owner´s Manual

Total load capacity - maximum total
weight limit specified of the load (pas-
sengers and cargo) for the vehicle.
This is the maximum combined weight
of occupants and cargo that can be
loaded into the vehicle. If the vehicle is
used to tow a trailer, the trailer tongue
weight must be included as part of the
cargo load. This information is located
on the Tire and Loading Information
label.

Cargo capacity - permissible weight of
cargo, the subtracted weight of occu-
pants from the load limit.
VEHICLE LOAD CAPACITYDo not exceed the load limit of your
vehicle shown as “The combined weight
of occupants and cargo” on the Tire and
Loading Information label. Do not exceed
the number of occupants shown as
“Seating Capacity” on the Tire and Load-
ing Information label.
To get “the combined weight of occu-
pants and cargo”, add the weight of all
occupants, then add the total luggage
weight. Examples are shown in the fol-
lowing illustration.

Steps for determining correct load
limit1. Locate the statement “The combined
weight of occupants and cargo should
never exceed XXX kg or XXX lbs” onyour vehicle’s placard.
2. Determine the combined weight of the
driver and passengers that will be
riding in your vehicle.3. Subtract the combined weight of the
driver and passengers from XXX kg or
XXX lbs.
4. The resulting figure equals the avail-
able amount of cargo and luggage
load capacity. For example, if the XXX
amount equals 1400 lbs. and there will
be five 150 lb. passengers in your
vehicle, the amount of available cargo
and luggage load capacity is 650 lbs.
(1400 − 750 (5×150) = 650 lbs) or
(640 − 340 (5×70) = 300 kg)
5. Determine the combined weight of
luggage and cargo being loaded on
the vehicle. That weight may not safely
exceed the available cargo and lug-
gage load capacity calculated in Step
4.
6. If your vehicle will be towing a trailer,
load from your trailer will be trans-
ferred to your vehicle. Consult this
manual to determine how this reduces
the available cargo and luggage load
capacity of your vehicle.

Before driving a loaded vehicle, confirm
that you do not exceed the Gross Vehicle
Weight Rating (GVWR) or the Gross
Axle Weight Rating (GAWR) for your
vehicle. See “Measurement of Weights”
later in this section.
Also check tires for proper inflation pres-
sures. See the Tire and Loading Informa-
tion label.LOADING TIPS
The GVW must not exceed GVWR or
GAWR as specified on the
F.M.V.S.S./C.M.V.S.S. certification la-
bel.

Do not load the front and rear axle to
the GAWR. Doing so will exceed the
GVWR.
WARNING

Properly secure all cargo with
ropes or straps to help prevent
it from sliding or shifting. Donot place cargo higher than the
seatbacks. In a sudden stop or
collision, unsecured cargo
could cause personal injury.

Do not load your vehicle any
heavier than the GVWR or the
maximum front and rear
GAWRs. If you do, parts of your
vehicle can break, tire damage
could occur, or it can change
the way your vehicle handles.
This could result in loss of con-
trol and cause personal injury.

Overloading not only could
shorten the life of your vehicle
and the tire, but can also cause
unsafe vehicle handling and
long braking distances. This
may cause a premature tire fail-
ure, which could result in a se-
rious accident and personal in-
jury. Failures caused by over
loading are not covered by thevehicle’s warranty.
MEASUREMENT OF WEIGHTSSecure loose items to prevent weight
shifts that could affect the balance of
your vehicle. When the vehicle is loaded,
drive to a scale and weigh the front and
the rear wheels separately to determine
axle loads. Individual axle loads should
not exceed either of the gross axle weight
ratings (GAWR). The total of the axle
loads should not exceed the gross ve-
hicle weight rating (GVWR). These rat-
ings are given on the vehicle certification
label. If weight ratings are exceeded,
move or remove items to bring all weights
below the ratings.

Roadster model:
Do not tow a trailer with your vehicle.
Coupe model:
Your new vehicle was designed to be used
primarily to carry passengers and cargo. Re-
member that towing a trailer places additional
loads on your vehicle’s engine, drive train, steer-
ing, braking and other systems.
A NISSAN Towing Guide (U.S. only) is available
on the website at www.nissanusa.com. This
guide includes information on trailer towing ca-
pability and the special equipment required for
proper towing.
WARNING
Overloading or improper loading of a
trailer and its cargo can adversely affect
vehicle handling, braking and perfor-
mance and may lead to accidents.
CAUTION

Do not tow a trailer or haul a heavy
load for the first 500 miles (800 km).Your engine, axle or other parts
could be damaged.

For the first 500 miles (800 km) that
you tow a trailer, do not drive over 50
mph (80 km/h) and do not make
starts at full throttle. This helps the
engine and other parts of your ve-
hicle wear in at the heavier loads.
MAXIMUM LOAD LIMITS
Maximum trailer loadsNever allow the total trailer load to exceed 1,000
lb(454 kg). The total trailer load equals trailer
weight plus its cargo weight. Towing loads
greater than 1,000 lb(454 kg) or using improper
towing equipment could adversely affect vehicle
handling, braking and performance.
The ability of a vehicle to tow a trailer is not only
related to the maximum trailer loads, but also the
places you plan to tow. Tow weights appropriate
for level highway driving may have to be reduced
on very steep grades or in low traction situations
(for example, on slippery boat ramps).
CAUTION
Vehicle damage resulting from im-
proper towing procedures are not cov-
ered by NISSAN warranties.

Tongue loadKeep the tongue load between 9 and 11% of the
total trailer load within the maximum tongue load
limits shown in the following Towing
Load/Specification chart. If the tongue load be-
comes excessive, rearrange cargo to allow for
proper tongue load.
Maximum gross vehicle weight/
maximum gross axle weightThe gross vehicle weight of the towing vehicle
must not exceed. GVWR shown on the
F.M.V.S.S./C.M.V.S.S. certification label. The
gross vehicle weight equals the combined
weight of the unloaded vehicle, passengers,
luggage, hitch, trailer tongue load and any other
optional equipment. In addition, front or rear
gross axle weight must not exceed GAWR
shown on the F.M.V.S.S./C.M.V.S.S. certifica-
tion label.

TOWING SAFETY
Trailer hitchChoose a proper hitch for a vehicle and trailer.
Make sure the trailer hitch is securely attached to
the vehicle, to help avoid personal injury or
property damage due to sway caused by cross-
winds, rough road surfaces or passing trucks.Hitch ballChoose a hitch ball of the proper size and weight
rating for your trailer:

The required hitch ball size is stamped on
most trailer couplers. Most hitch balls also
have the size printed on top of the ball.

Choose the proper class hitch ball based on
the trailer weight.

The diameter of the threaded shank of the
hitch ball must be matched to the ball mount
hole diameter. The hitch ball shank should be
TI1011M
TI1012M
9-18
Technical and consumer information


07.2.9/Z33-D/V5.0


no more than 1/16″smaller than the hole in
the ball mount.

The threaded shank of the hitch ball must be
long enough to be properly secured to the
ball mount. There should be at least 2 threads
showing beyond the lock washer and nut.
Class I hitchClass I trailer hitch equipment (receiver, ball
mount and hitch ball) can be used to tow trailers
of a maximum weight of 2,000 lb(909 kg).
You may add Class I trailer hitch equipment to
the vehicle that has a 2,000 lb(909 kg) maxi-
mum weight rating, but your vehicle is only
capable of towing the maximum trailer weights
shown in the Towing Load/Specification Chart
earlier in this section.
CAUTION

Do not use axle-mounted hitches.

The hitch should not be attached to
or affect the operation of the impact-
absorbing bumper.

Do not modify the vehicle exhaust
system, brake system, etc. to install atrailer hitch.

To reduce the possibility of addi-
tional damage if a vehicle is struck
from the rear, where practical, re-
move the hitch and/or receiver when
not in use.

After the hitch is removed, seal the
bolt holes to prevent exhaust fumes,
water or dust from entering the pas-
senger compartment.

Regularly check that all trailer hitch
mounting bolts are securely mounted.Tire pressures
When towing a trailer, inflate the ve-
hicle tires to the recommended cold
tire pressure indicated on the Tire and
Loading Information label.

Trailer tire condition, size, load rating
and proper inflation pressure should
be in accordance with the trailer and
tire manufacturers’ specifications.
Safety chainsAlways use a suitable chain between a vehicle
and the trailer. The safety chain should be
crossed and should be attached to the hitch, not
to the vehicle bumper or axle. Be sure to leave
enough slack in the chain to permit turning
corners.Trailer lights
CAUTION
When splicing into the vehicle electrical
system, a commercially available
power-type module/converter must be
used to provide power for all trailer
lighting. This unit uses the vehicle bat-
tery as a direct power source for all
trailer lights while using the vehicle tail
light, stoplight and turn signal circuits
as a signal source. The module/
converter must draw no more than 15
milliamps from the stop and tail lamp
circuits. Using a module/converter that
exceeds these power requirements may
damage the vehicle’s electrical system.

the proper equipment and to have it
installed.
Trailer lights should comply with federal and/or
local regulations. When wiring the vehicle for
towing, connect the stop and tail light pickup
into the vehicle electrical circuit at a point be-
tween the sensor and stop light or light switch.Trailer brakesIf your trailer is equipped with a braking system,
make sure it conforms to federal and/or local
regulations and that it is properly installed.
WARNING
Never connect a trailer brake system
directly to the vehicle brake system.Pre-towing tips
Be certain a vehicle maintains a level position
when a loaded and/or unloaded trailer is
hitched. Do not drive the vehicle if it has an
unusual nose-up or nose-down condition;
check for improper tongue load, overload,
worn suspension or other possible causes of
these conditions.
Always secure items in the trailer to prevent
load shifts while driving.

Load the trailer so approximately 60% of the
trailer load is in the front half and 40% is in
the back half.

Check your hitch, trailer tire pressure, vehicle
tire pressure, trailer light operation, and trailer
wheel lug nuts every time you attach a trailer
to the vehicle.

Be certain your rear view mirrors conform to
all federal, state and/or local regulations. If
not, install any mirrors required for towing
before driving the vehicle.
Trailer towing tipsIn order to gain skill and an understanding of the
vehicle’s behavior, you should practice turning,
stopping and backing up in an area which is free
from traffic. Steering stability, and braking per-
formance will be somewhat different than under
normal driving conditions.

Always secure items in the trailer to prevent
load shift while driving.

Avoid abrupt starts, acceleration or stops.

Avoid sharp turns or lane changes.

Always drive a vehicle at a moderate speed.
Some states or provinces have specificspeed limits for vehicles that are towing
trailers. Obey the local speed limits.

When backing up, hold the bottom of the
steering wheel with one hand. Move your
hand in the direction in which you want the
trailer to go. Make small corrections and back
up slowly. If possible, have someone guide
you when you are backing up.

Always block the wheels on both vehicle and
trailer when parking. Parking on a slope is not
recommended; however, if you must do so,
and if a vehicle is equipped with automatic
transmission, first apply the parking brake
and block the wheels, and then move the
transmission selector lever into the P (Park)
position. If you move the selector lever to the
P (Park) position before blocking the wheels
and applying the parking brake, the transmis-
sion may get damaged.

When going down a hill, shift into a lower
gear and use the engine braking effect.
When going up a long grade, downshift the
transmission to a lower gear and reduce
speed to reduce chances of engine overload-
ing and/or overheating.

If the engine coolant rises to an extremely
high temperature when the air conditioning
system is on, turn off the air conditioner.
Coolant heat can be additionally vented by

opening the windows, switching the fan con-
trol to high and setting the temperature con-
trol to the HOT position.

Trailer towing consumes more fuel than nor-
mal circumstances.

Avoid towing a trailer for the first 500 miles
(800 km).

Have a vehicle serviced more often than at
intervals specified in the recommended main-
tenance schedule.

When making a turn, your trailer wheels will
be closer to the inside of the turn than your
vehicle wheels. To compensate for this, make
a larger than normal turning radius during the
turn.

Crosswinds and rough roads will adversely
affect vehicle/trailer handling, possibly caus-
ing vehicle sway. When being passed by
larger vehicles, be prepared for possible
changes in crosswinds that could affect ve-
hicle handling. If swaying does occur, firmly
grip the steering wheel, steer straight ahead,
and immediately (but gradually) reduce ve-
hicle speed. This combination will help stabi-
lize the vehicle. Never increase speed.

Be careful when passing other vehicles.
Passing while towing a trailer requires con-
siderably more distance than normal passing.Remember the length of the trailer must also
pass the other vehicle before you can safely
change lanes.

To maintain engine braking efficiency and
electrical charging performance, do not use
6th gear (manual transmission) or 5th posi-
tion (automatic transmission).

Avoid holding the brake pedal down too long
or too frequently. This could cause the brakes
to overheat, resulting in reduced braking ef-
ficiency.

Increase your following distance to allow for
greater stopping distances while towing a
trailer. Anticipate stops and brake gradually.

Do not use cruise control while towing a
trailer.

Check your hitch, trailer wiring harness con-
nections, and trailer wheel lug nuts after 50
miles (80 km) of travel and at every break.

When stopped in traffic for long periods of
time in hot weather, put the vehicle in the P
(Park) position.
When towing a trailer, change transmis-
sion oil more frequently. For additional
information, see the “8. Maintenance and
do-it-yourself” section.Towing your vehicle with all four wheels on the
ground is sometimes called flat towing. This
method is sometimes used when towing a ve-
hicle behind a recreational vehicle, such as a
motor home.
CAUTION

Failure to follow these guidelines
can result in severe transmission
damage.

Whenever flat towing your vehicle,
always tow forward, never backward.

DO NOT tow any automatic transmis-
sion vehicle with all four wheels on
the ground (flat towing). Doing so
WILL DAMAGE internal transmission
parts due to lack of transmission lu-
brication.

For emergency towing procedures,
refer to “Towing recommended by
NISSAN” in the “6. In case of emer-
gency” section of this manual.FLAT TOWINGTechnical and consumer information
