Tire wear and damage
WARNING
.
Tires should be periodically in-
spected for wear, cracking, bul-
ging or objects caught in the
tread. If excessive wear, cracks,
bulging or deep cuts are found,
the tire(s) should be replaced.
. The original tires have built-in

the standard tire at the first oppor-
tunity to avoid possible tire or differ-
ential damage
. Drive carefully while the spare tire is
installed. Avoid sharp turns and
abrupt braking while driving. The
vehicle driving performance may be
affected when driving on wet or
snow covered roads.
. When the spare tire is installed, the
following systems may not work
correctly.
— Tire Pressure Monitoring System (TPMS)
— Vehicle Dynamic Control (VDC) System
. Periodically check spare tire inflation
pressure. Always keep the spare tire
inflated to the pressure specification
shown on the Tire and Loading
Information label. For Tire and Load-
ing Information label location, see
“Tire and Loading Information label”
in the index of this manual.
. With the spare tire installed do not
drive your vehicle at speeds faster
than 70 MPH (112 km/h).
. When driving on roads covered with
snow or ice, the spare tire should be
used on the front wheels and original tire used on the rear wheels (drive
wheels). Use tire chains only on the
two rear original tires.
. Do not use the spare tire on other
vehicles.
. Do not use more than one spare tire
at the same time.
CAUTION
Do not use tire chains on the spare tire.
Tire chains will not fit properly and may
cause damage to the vehicle.

VEHICLE LOAD CAPACITY
Do 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 Capa-
city” on the Tire and Loading Infor-
mation label.
To get “the combined weight of
occupants and cargo”, add the weight
of all occupants, then add the total
luggage weight. Examples are shown
in the illustration.
Steps For Determining Correct
Load Limit
1.Locate the statement “The com-
bined weight of occupants and
cargo should never exceed XXX
kg or XXX lbs” on your 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 fromXXX kg or XXX lbs.
4.The resulting figure equals the
available amount of cargo and
luggage load capacity. For exam-
ple, 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 x 150) = 650 lbs)
5.Determine the combined weight of
luggage and cargo being loaded on
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 luggage load capacity
of your vehicle.
Before driving a loaded vehicle, con-
firm 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” (P.10-19).)
Also check tires for proper inflation
pressures. See the Tire and Loading
Information label.
Technical and consumer information10-17

10-26Technical and consumer information
measured reference height when loaded,
the vehicle may handle unpredictably
which could cause a loss of vehicle
control and cause serious personal injury
or property damage.
Sway control device
Sudden maneuvers, wind gusts and buffet-
ing 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.
Class I hitch
Class I trailer hitch equipment (receiver, ball
mount and hitch ball) can be used to tow
trailers of a maximum weight of 2,000 lb
(907 kg).
Class II hitch
Class II trailer hitch equipment (receiver, ball
mount and hitch ball) can be used to tow
trailers of a maximum weight of 3,500 lb
(1,588 kg).
Class III hitch
Class III trailer hitch equipment (receiver, ball
mount and hitch ball) can be used to tow
trailers of a maximum weight of 5,000 lb
(2,267 kg).
Class IV hitch
Class IV trailer hitch equipment (receiver, ball
mount and hitch ball) can be used to tow
trailers of a maximum weight of 10,000 lb
(4,545 kg). A weight distributing hitch
should be used to tow trailers that weigh
over 5,000 lb (2,267 kg).
Your vehicle may be equipped with Class IV
trailer hitch equipment that has a 10,000 lb
(4,545 kg) maximum weight rating, but your
vehicle is only capable of towing the max-
imum trailer weights shown in the “Towing
Load/Specification” chart earlier in this
section.
CAUTION
.Do not use axle-mounted hitches.
. Do not modify the vehicle exhaust
system, brake system, etc.
. Do not attach any additional hitches
to your vehicle because a hitch is
already mounted to your vehicle frame.
Tire pressures
.
When towing a trailer, inflate the
vehicle tires to the recommended
cold tire pressure indicated on the
Tire and Loading Information la-
bel.
. Trailer tire condition, size, load
rating and proper inflation pres-
sure should be in accordance with
the trailer and tire manufacturers’
specifications.
Safety chains
Always use a suitable chain 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 corners.

2. When the trailer sway stops, gentlyapply the brakes and pull to the side of
the road in a safe area.
3. Try to rearrange the trailer load so it is balanced.
NOTE:
Trailer Sway Control cannot reduce trailer
sway in all situations.
FLAT TOWING
Towing your vehicle with all four wheels on
the ground is sometimes called flat towing.
This method is sometimes used when towing
a vehicle 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 back-
ward.
. DO NOT tow any automatic trans-
mission vehicle with all four wheels
on the ground (flat towing). Doing so
WILL DAMAGE internal transmis-
sion parts due to lack of transmission
lubrication. .
DO NOT tow a Four-Wheel Drive
(4WD) vehicle with any of the wheels
on the ground. Doing so may cause
serious and expensive damage to the
powertrain.
. For emergency towing procedures
refer to “Towing recommended by
INFINITI” (P.6-16).
Automatic Transmission
Four-Wheel Drive (4WD) models:
Do not tow a 4WD vehicle with any of the
wheels on the ground.
Two-Wheel Drive (2WD) models:
To tow a vehicle equipped with an automatic
transmission, an appropriate vehicle dolly
MUST be placed under the towed vehicle’s
drive wheels. Alwaysfollow the dolly man-
ufacturer’s recommendations when using
their product. DOT (Department Of Transportation) Qual-
ity Grades: All passenger car tires must
conform to federal safety requirements in
addition to these grades.
Quality grades can be found where applic-
able on the tire sidewall between tread
shoulder and maximum section width. For
example:
Treadwear 200 Traction AA Temperature A
TREADWEAR
The treadwear grade is a comparative rating
based on the wear rate of the tire when
tested under controlled conditions on a
specified government test course. For ex-
ample, a tire graded 150 would wear one
and one-half (1 1/2) times as well on the
government course as a tire graded 100.
The relative performance of tires depends
upon actual conditions of their use, however,
and may depart significantly from the norm
due to variations in driving habits, service
practices and differences in road character-
istics and climate.
Technical and consumer information10-31
UNIFORM TIRE QUALITY GRADING

10-32Technical and consumer information
TRACTION AA, A, B AND C
The traction grades, from highest to lowest,
are AA, A, B and C. Those grades represent
the tire’s ability to stop on wet pavement as
measured under controlled conditions on
specified government test surfaces of as-
phalt and concrete. A tire marked C may
have poor traction performance.
WARNING
The traction grade assigned to this tire is
based on straight-ahead braking trac-
tion tests, and does not include accel-
eration, cornering, hydroplaning, or peak
traction characteristics.
TEMPERATURE A, B AND C
The temperature grades A (the highest), B,
and C, representing the tire’s resistance to
the generation of heat and its ability to
dissipate heat when tested under controlled
conditions on a specified indoor laboratory
test wheel. Sustained high temperature can
cause the material of the tire to degenerate
and reduce tire life, and excessive tempera-
ture can lead to sudden tire failure. The
grade C corresponds to a level of perfor-
mance which all passenger car tires must
meet under the Federal Motor VehicleSafety Standard No. 109. Grades B and A
represent higher levels of performance on
the laboratory test wheel than the minimum
required by law.
WARNING
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded. Excessive
speed, under-inflation, or excessive
loading, either separately or in combina-
tion, can cause heat build-up and possi-
ble tire failure.
