Checking the tire pressure GUID-CC708595-2C70-4CAE-BDC3-D716681157B7
1.Remove the valve stem cap from
the tire.
2.Press the pressure gauge
squarely onto the valve stem. Do
not press too hard or force the
valve stem sideways, or air will
escape. If the hissing sound of air
escaping from the tire is heard
while checking the pressure, re-
position the gauge to eliminate
this leakage. 3.Remove the gauge.
4.Read the tire pressure on the
gauge stem and compare it to
the specification shown on the
Tire and Loading Information la-
bel.
5.Add air to the tire as needed. If
too much air is added, press the
core of the valve stem briefly with
the tip of the gauge stem to
release pressure. Recheck the
pressure and add or release air
as needed.
6.Install the valve stem cap.
7.Check the pressure of all other
tires, including the spare.

TIRE LABELING GUID-7CDDB6DE-92AD-4E32-995B-54060312AD14
Federal law requires tire manufac-
turers to place standardized informa-
tion on the sidewall of all tires. This
information identifies and describes
the fundamental characteristics of
the tire and also provides the tire
identification number (TIN) for safety
standard certification. The TIN can be
used to identify the tire in case of a
recall.

Maximum permissible inflation
pressure
This number is the greatest
amount of air pressure that
should be put in the tire. Do
not exceed the maximum per- missible inflation pressure.
* 5
Maximum load rating
This number indicates the max-
imum load in kilograms and
pounds that can be carried by
the tire. When replacing the tires
on the vehicle, always use a tire
that has the same load rating as
the factory installed tire.
* 6
Term of “ tubeless ” or “ tube
type ”
Indicates whether the tire re-
quires an inner tube ( “ tube
type ” ) or not ( “ tubeless ” ).
* 7
The word “ radial ”
The word “ radial ” is shown, if
the tire has radial structure.
* 8

TYPES OF TIRES GUID-42D58B1A-32E5-4966-9D89-2C4B16EEE249
WARNING . When changing or replacing tires, be
sure all four tires are of the same type
(Example: Summer, All Season or Snow)
and construction. An INFINITI retailer
may be able to help you with information
about tire type, size, speed rating and
availability.
. Replacement tires may have a lower
speed rating than the factory equipped
tires, and may not match the potential
maximum vehicle speed. Never exceed
the maximum speed rating of the tire.
. Replacing tires with those not originally

fected.
Tire chains must be installed only on the
rear wheels and not on the front wheels.
Never install tire chains on a TEMPORARY
USE ONLY spare tire.
Do not use tire chains on dry roads. Driving
with tire chains in such conditions can
cause damage to the various mechanisms
of the vehicle due to some overstress. SDI1662
CHANGING WHEELS AND TIRES GUID-2274D4EA-A493-4122-8F01-70F7A39EC40C
Tire rotation (Models equipped with
same size tires on all wheels) GUID-A3A28418-DE08-410B-A7FA-043A8A0FEFF1
INFINITI recommends rotating the
tires every 7,500 miles (12,000 km).
(See “ Flat tire ” (P.6-2) for tire repla-
cing procedures.)
As soon as possible, tighten the
wheel nuts to the specified torque
with a torque wrench.
Wheel nut tightening torque:
80 ft-lb (108 N·m) The wheel nuts must be kept tigh-
tened to the specification at all
times. It is recommended that wheel
nuts be tightened to the specifica-
tion at each tire rotation interval.
WARNING . After rotating the tires, check and
adjust the tire pressure.
. Retighten the wheel nuts when
the vehicle has been driven for
600 miles (1,000 km) (also in
cases of a flat tire, etc.).
. Do not include the T-type spare
tire or any other small size spare
tire in the tire rotation.
. For additional information regard-
ing tires, refer to “ Important Tire
Safety Information ” (US) or “ Tire
Safety Information ” (Canada) in
the Warranty Information Booklet.

different size tires on front and
rear) GUID-42591FA5-788F-4ABA-B1AA-2564E2B3FCB6
Tires cannot be rotated on this
vehicle, as front tires are a different
size from rear tires.
A pin is on the front brake rotor to
prevent the rear wheels from being
installed in place of the front wheels.
The spare tire can be installed in
place of the front and rear wheels.
When installing the spare tire in the
front wheel, the hole in the spare tire
wheel must be aligned with the pin
on the brake rotor.
WARNING. Retighten the wheel nuts when
the vehicle has been driven for
600 miles (1,000 km) (also in
cases of a flat tire, etc.).

CAUTION. Always use tires of the same type, size,
brand, construction (bias, bias-belted or
radial), and tread pattern on all four
wheels. Failure to do so may result in a
circumference difference between tires
on the front and rear axles which will
cause excessive tire wear and may
damage the transmission, transfer case
and differential gears.
. ONLY use spare tires specified for the
AWD model.
If excessive tire wear is found, it is
recommended that all four tires be re-
placed with tires of the same size, brand,
construction and tread pattern. The tire
pressure and wheel alignment should also
be checked and corrected as necessary.
Contact an INFINITI retailer.
Wheel balance GUID-E8819382-6D86-409C-A6FD-5113A53508AB
Unbalanced wheels may affect vehicle
handling and tire life. Even with regular
use, wheels can get out of balance. There-
fore, they should be balanced as required. Wheel balance service should be per-
formed with the wheels off the vehicle.
Spin balancing the wheels on the vehicle
could lead to mechanical damage.
For additional information regarding tires,
refer to “ Important Tire Safety Information ”
(US) or “ Tire Safety Information ” (Canada)
in the INFINITI Warranty Information Book-
let.
Care of wheels GUID-C1AC6B0A-3969-4BA4-85FF-DEEAE1EBA8AB
See “ Cleaning exterior ” (P.7-2) for details
about care of the wheels.
Spare tire (TEMPORARY USE ONLY
(T-type) spare tire) GUID-3D33E4D2-DC59-460C-941C-8160D646B5B6
Observe the following precautions if the T-
type spare tire must be used, otherwise
your vehicle could be damaged or involved
in an accident.
WARNING . The T-type spare tire should be used for
emergency use. It should be replaced
with the standard tire at the first
opportunity to avoid possible tire or
differential damage. . Drive carefully while the TEMPORARY
USE ONLY spare tire is installed. Avoid
sharp turns and abrupt braking while
driving.
. Periodically check spare tire inflation
pressure. Always keep the pressure of
the TEMPORARY USE ONLY spare tire at
60 psi (420 kPa, 4.2 bar). Always keep
the pressure of the full size spare tire (if
so equipped) at the recommended pres-
sure for standard tires, as indicated on
the Tire and Loading Information label.
For Tire and Loading Information label
location, see “ Tire and Loading Informa-
tion label ” in the index of this manual.
. With the TEMPORARY USE ONLY spare
tire installed do not drive your vehicle at
speeds faster than 50 MPH (80 km/h).
. When driving on roads covered with
snow or ice, the TEMPORARY USE ONLY
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.
. Tire tread of the TEMPORARY USE ONLY
spare tire will wear at a faster rate than
the standard tire. Replace the spare tire
as soon as the tread wear indicators

Be sure everyone in your vehicle is
in a seat and using a seat belt
properly.
TERMS GUID-3442F756-0B54-4F09-A262-23D84A9CA9AC
It is important to familiarize yourself
with the following terms before
loading your vehicle: .
Curb Weight (actual weight of your
vehicle) - vehicle weight includ-
ing: standard and optional equip-
ment, 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 informa-
tion is located on the F.M.V.S.S./
C.M.V.S.S. label. .
GAWR (Gross Axle Weight Rating) -
maximum weight (load) limit spe-
cified 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, Load
limit, Total load capacity - max-
imum total weight limit specifiedVEHICLE LOADING INFORMATION

Black plate (472,1)
[ Edit: 2012/ 1/ 17 Model: V36-D ]9-22 Technical and consumer information3.
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 vehi-
cle, 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
calculated 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,
confirm that you do not exceed the
Gross Vehicle Weight Rating (GVWR)
or the Gross Axle Weight Rating
(GAWR) for your vehicle. (See “ Mea-
surement of weights ” (P.9-23).)
Also check tires for proper inflation
pressures. See the Tire and Loading
Information label.
LOADING TIPS GUID-E6D7CA83-EA67-4B48-B261-156FACE4D953
.
The GVW must not exceed GVWR
or GAWR as specified on the F.M.V.
S.S./C.M.V.S.S. certification label. .
Do not load the front and rear axle
to the GAWR. Doing so will exceed
the GVWR.
WARNING .
Properly secure all cargo to help
prevent it from sliding or shifting.
Do not 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 control and cause personal
injury. .
Overloading could not only short-
en the life of your vehicle and the
tires, but also could lead to
hazardous vehicle handling and
long braking distance. This may
cause a premature tire malfunc-
tion, which could result in a
serious accident and personal in-
jury. Failures caused by overload-
ing are not covered by the
vehicle ’ s warranty.
