Pressure Monitoring System (TPMS)” (P.6-
3).
Tire inflation pressure
Check the pressure of the tires (in-
cluding the spare) often and always
prior to long distance trips. The
recommended tire pressure specifica-
tions are shown on the Tire and
Loading Information label under the
“Cold Tire Pressure” heading. The Tire
and Loading Information label is
affixed to the driver side center pillar.
Tire pressures should be checked
regularly because:
.Most tires naturally lose air over
time.
. Tires can lose air suddenly when
driven over potholes or other ob-
jects or if the vehicle strikes a curb
while parking.
The tire pressures should be checked
when the tires are cold. The tires are
considered COLD after the vehicle
has been parked for 3 or more hours,
or driven less than 1 mile (1.6 km) at
moderate speeds. TPMS with Tire Inflation Indicator
provides visual and audible signals
outside the vehicle for inflating the
tires to the recommended COLD tire
pressure. (See “TPMS with Tire Infla-
tion Indicator” (P.5-8) about the
TPMS with Tire Inflation Indicator.)
Incorrect tire pressure, including un-
der inflation, may adversely affect
tire life and vehicle handling.
WARNING
.
Improperly inflated tires can fail
suddenly and cause an accident.
. The Gross Vehicle Weight rat-
ing (GVWR) is located on the F.
M.V.S.S./C.M.V.S.S. label. The
vehicle weight capacity is indi-
cated on the Tire and Loading
Information label. Do not load
your vehicle beyond this capa-
city. Overloading your vehicle
may result in reduced tire life,
unsafe operating conditions
due to premature tire failure,
or unfavorable handling char- acteristics and could also lead
to a serious accident. Loading
beyond the specified capacity
may also result in failure of
other vehicle components.
. Before taking a long trip, or
whenever you heavily load your
vehicle, use a tire pressure
gauge to ensure that the tire
pressures are at the specified
level.
. For additional information re-
garding tires, refer to “Impor-
tant Tire Safety Information”
(US) or “Tire Safety Informa-
tion” (Canada) in the Warranty
Information Booklet.

Tire and Loading Information label
Seating capacity: The maximum
number of occupants that can be
seated in the vehicle.
Vehicle load limit: See “Vehicle
loading information” (P.10-17).
Original size: The size of the tires
originally installed on the vehicle
at the factory.
Cold tire pressure: Inflate the
tires to this pressure when the
tires are cold. Tires are consid-
ered COLD after the vehicle hasbeen parked for 3 or more hours,
or driven less than 1 mile (1.6 km)
at moderate speeds. The recom-
mended cold tire inflation is set
by the manufacturer to provide
the best balance of tire wear,
vehicle handling, driveability, tire
noise, etc., up to the vehicle’s
GVWR.

.The original tires have built-in
tread wear indicators. When
wear indicators are visible, the
tire(s) should be replaced.
. Tires degrade with age and use.
Have tires, including the spare,
over 6 years old checked by a
qualified technician, because
some tire damage may not be
obvious. Replace the tires as
necessary to prevent tire failure
and possible personal injury.
. Improper service of the spare
tire may result in serious perso-
nal injury. If it is necessary to
repair the spare tire, it is re-
commended you visit an
INFINITI retailer for this ser-
vice.
. For additional information re-
garding tires, refer to “Impor-
tant Tire Safety Information”
(US) or “Tire Safety Informa-
tion” (Canada) in the Warranty
Information Booklet.Replacing wheels and tires
When replacing a tire, use the same size,
tread design, speed rating and load carrying
capacity as originally equipped. (See “Speci-
fications” (P.10-8) for recommended types
and sizes of tires and wheels.)
After the ignition switch is placed in the ON
position, it may take a period of time for the
tire pressure to be displayed in the vehicle
information display while the vehicle is
driven. Depending on the radio wave circum-
stance, tire pressure may not correctly be
displayed.
WARNING
. The use of tires other than those
recommended or the mixed use of
tires of different brands, construc-
tion (bias, bias-belted, radial or run-
flat), or tread patterns can adversely
affect the ride, braking, handling,
ground clearance, body-to-tire clear-
ance, tire chain clearance, speed-
ometer calibration, headlight aim
and bumper height. Some of these
effects may lead to accidents and
could result in serious personal injury.
. For Two-Wheel Drive (2WD) models,
if your vehicle was originally equipped with 4 tires that were the
same size and you are only replacing
2 of the 4 tires, install the new tires
on the rear axle. Placing new tires on
the front axle may cause loss of
vehicle control in some driving condi-
tions and cause an accident and
personal injury.
. If the wheels are changed for any
reason, always replace with wheels
which have the same off-set dimen-
sion. Wheels of a different off-set
could cause premature tire wear,
degrade vehicle handling character-
istics and/or interference with the
brake discs/drums. Such interference
can lead to decreased braking effi-
ciency and/or early brake pad/shoe
wear. See “Wheels and tires” (P.10-
9) of this manual for wheel off-set
dimensions.
. Since the spare tire is not equipped
with the TPMS, when a spare tire is
mounted or a wheel is replaced, the
TPMS will not function and the low
tire pressure warning light will flash
for approximately 1 minute. The light
will remain on after 1 minute. Have
your tires replaced and/or TPMS
system reset as soon as possible. It
is recommended you visit an INFINITI
retailer for these services.

TERMS
It is important to familiarize yourself
with the following terms before load-
ing your vehicle:
.Curb Weight (actual weight ofyour vehicle) - vehicle weight in-
cluding: standard and optional
equipment, fluids, emergency
tools, and spare tire assembly. This
weight does not include passen- gers and cargo.
.GVW (Gross Vehicle Weight) -
curb weight plus the combined
weight of passengers and cargo.
.GVWR (Gross Vehicle Weight Rat-ing) - maximum total combined
weight of the unloaded vehicle,
passengers, luggage, hitch, trailer
tongue load and any other op-
tional equipment. This information
is located on the F.M.V.S.S./C.M.
V.S.S. label.
.GAWR (Gross Axle Weight Rating)- maximum weight (load) limit
specified for the front or rear axle.
This information is located on the
F.M.V.S.S./C.M.V.S.S. label.
.GCWR (Gross Combined Weight
Rating) - The maximum total
weight rating of the vehicle, pas-
sengers, cargo, and trailer.
.Vehicle Capacity Weight, Loadlimit, Total load capacity - max-
imum total weight limit specified
of the load (passengers and cargo)
for the vehicle. This is the max-
imum combined weight of occu- pants 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 la-
bel.
.Cargo capacity - permissible
weight of cargo, the weight of
total occupants weight subtracted
from the load limit.

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 from
XXX 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 or
640 − 340 (5 x 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 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)
