4. R: The ªRº stands for radial.
5. Two-digit number (15): This number
is the wheel or rim diameter in
inches.
6. Two- or three-digit number (95): This
number is the tire's load index. It is
a measurement of how much weight
each tire can support. You may not
find this information on all tires be-
cause it is not required by law.
7. H: Tire speed rating. You should not
drive the vehicle faster than the tire
speed rating.

TIN (Tire Identification Number) for a
new tire (example: DOT XX XX XXX
XXXX)
1. DOT: Abbreviation for the ªDepart-
ment of Transportationº. The
symbol can be placed above,
below or to the left or right of
the Tire Identification Number.
2. Two-digit code: Manufacturer's iden-
tification mark
3. Two-digit code: Tire size 4. Three-digit code: Tire type code (Op-
tional)
5. Three-digit code: Date of Manufac-
ture
6. Four numbers represent the week
and year the tire was built. For ex-
ample, the numbers 3103 mean the
31st week of 2003. If these numbers
are missing, then look on the other
sidewall of the tire.
q 3
Tire ply composition and material
The number of layers or plies of
rubber-coated fabric in the tire. Tire
manufacturers also must indicate
the materials in the tire, which in-
clude steel, nylon, polyester, and
others.
q 4
Maximum permissible inflation pres-
sure
This number is the greatest amount
of air pressure that should be put in
the tire. Do not exceed the
maximum permissible inflation pres-
sure. SDI1607

O Do not use abrasive cleaners when
washing the wheels.
O Inspect wheel rims regularly for dents or
corrosion. Such damage may cause loss
of pressure or poor seal at the tire bead.
O INFINITI recommends that the road
wheels be waxed to protect against
road salt in areas where it is used
during winter.
Spare tire (TEMPORARY USE ONLY
spare tire (T-type)) Observe the following precautions if the
T-type spare tire must be used, otherwise
your vehicle could be damaged or in-
volved in an accident.
CAUTIONO The T-type spare tire should be used only
for an emergency. It should be replaced by
a standard tire at the first opportunity.
O Drive carefully while the T-type spare tire
is installed.
Avoid sharp turns and abrupt braking
while driving. O Periodically check the T-type spare tire
inflation pressure, and always keep it at
60 psi (420 kPa, 4.2 bar).
O With the T-type spare tire installed, do
not drive your vehicle at speeds faster
than 50 MPH (80 km/h).
O When driving on roads covered with
snow or ice, the T-type spare tire should
be used on the front wheel and the origi-
nal tire used on the rear wheels (drive
wheels). Use tire chains only on the rear
two original tires (Sedan).
O
Tire tread of the T-type spare tire will wear
at a faster rate than the original tire. Re-
place the T-type spare tire as soon as the
tread wear indicators appear.
O Do not use the T-type spare tire on other
vehicles.
O Do not use more than one T-type spare
tire at the same time.
O Do not tow a trailer while the T-type
spare tire is installed. CAUTION O Do not use tire chains on a T-type spare
tire. Tire chains will not fit properly on
the T-type spare tire and may cause
damage to the vehicle.
O Because the T-type spare tire is smaller
than the original tire, ground clearance
is reduced. To avoid damage to the ve-
hicle do not drive over obstacles. Also do
not drive the vehicle through an auto-
matic car wash since it may get caught.

the vehicle. That weight may not
safely exceed the available cargo
and luggage load capacity calcu-
lated in Step 4.
6. If your vehicle will be towing a
trailer, load from your trailer will be
transferred to your vehicle. Consult
this manual to determine how this
reduces the available cargo and lug-
gage load capacity of your vehicle.
Before driving a loaded vehicle, confirm
that you do not exceed the Gross Ve-
hicle 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
pressures. See the Tire and Loading In-
formation label.
LOADING TIPS
O The GVW must not exceed GVWR or
GAWR as specified on the F.M.V.S.S./C.M.V.S.S. certification
label.
O Do not load the front and rear axle
to the GAWR. Doing so will exceed
the GVWR.
WARNINGO Properly secure all cargo with
ropes or straps to help prevent it
from sliding or shifting. Do not
place cargo higher than the seat-
backs. In a sudden stop or colli-
sion, unsecured cargo could cause
personal injury.
O 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 control and cause personal
injury. O Overloading not only can shorten
the life of your vehicle and the tire,
but can also cause unsafe vehicle
handling and longer braking dis-
tances. This may cause a prema-
ture tire failure which could result
in a serious accident and personal
injury. Failures caused by over-
loading are not covered by the ve-
hicle's warranty.
MEASUREMENT OF WEIGHTS
Secure 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 ex-
ceed the gross vehicle weight rating
(GVWR). These ratings are given on the
vehicle certification label. If weight rat-
ings are exceeded, move or remove
items to bring all weights below the rat-
ings. Technical and consumer information

CAUTIONO Do not use axle-mounted hitches.
O The hitch should not be attached to or af-
fect the operation of the impact-
absorbing bumper.
O Do not modify the vehicle exhaust
system, brake system, etc. to install a
trailer hitch.
O To reduce the possibility of additional
damage if your vehicle is struck from the
rear, where practical, remove the hitch
and/or receiver when not in use.
O After the hitch is removed, seal the bolt
holes to prevent exhaust fumes, water or
dust from entering the passenger com-
partment.
O Regularly check that all trailer hitch
mounting bolts are securely mounted. Tire pressures
O When towing a trailer, inflate the ve-
hicle tires to the recommended cold
tire pressure indicated on the Tire
and Loading Information label.
O Trailer tire condition, size, load
rating and proper inflation pressure
should be in accordance with the
trailer and tire manufacturers' speci-
fications.
Safety chains Always use a suitable chains between
your vehicle and the trailer. The safety
chains 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 chains to permit turning cor-
ners.
Trailer lights
CAUTION When splicing into the vehicle electrical sys-
tem, a commercially available power-type module/converter must be used to provide
power for all trailer lighting. This unit uses
the vehicle battery 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. See a reputable trailer
dealer to obtain the proper equipment and to
have it installed.
Trailer lights should comply with federal
and/or local regulations. For assistance in
hooking up trailer lights, contact an
INFINITI dealer or reputable trailer dealer.
Trailer brakes If your trailer is equipped with a braking
system, make sure it conforms to federal
and/or local regulations and that it is
properly installed.
