2013 INFINITI JX flat tire

●When a spare tire is mounted or a wheel
is replaced, tire pressure will not be
indicated, 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.
Contact your INFINITI retailer as soon
as possible for tire replacement and/or
system resetting.
● Replacing tires with those not originally
specified by INFINITI could affect the
proper operation of the TPMS.
● Do not inject any tire liquid or aerosol
tire sealant into the tires, as this may
cause a malfunction of the tire pressure
sensors.
CHANGING A FLAT TIRE
If you have a flat tire, follow the instructions be-
low:
Stopping the vehicle
1. Safely move the vehicle off the road and
away from traffic.
2. Turn on the hazard warning flashers.
3. Park on a level surface and apply the parking brake. Move the shift selector to P (Park) . 4. Turn off the engine.
5. Raise the hood to warn other traffic and to
signal professional road assistance person-
nel that you need assistance.
6. Have all passengers get out of the vehicle and stand in a safe place, away from traffic
and clear of the vehicle.
WARNING
●Make sure the parking brake is securely
applied and the automatic transmission
is shifted into P (Park) .
● Never change tires when the vehicle is
on a slope, ice or slippery areas. This is
hazardous.
● Never change tires if oncoming traffic is
close to your vehicle. Wait for profes-
sional road assistance.
Blocking wheels
Place suitable blocks1at both the front and
back of the wheel diagonally opposite the flat tire
2to prevent the vehicle from moving when it is
jacked up.
WARNING
Be sure to block the wheel as the vehicle
may move and result in personal injury.

release.
● Insert the flat end of the wheel nut wrench
Finto the slot of the fastenerD, and
rotate counterclockwise to release the
jack.
5. The lowering mechanism for the spare tire is located on the passenger side of the cargo
area. Remove the cover
Gto access the
spare tire winch. 6. Insert the spare tire winch socket
Hto the
lowering mechanism nut.
7. To lower the spare tire, insert the wheel nut wrench
Fto the extensionEand insert
the T-shaped end to the winch socket
H
and rotate counterclockwise.
8. After removing the spare tire from under the vehicle, be sure to crank the cable up to
stow it.
NOTE:
Fully lower the spare tire below the vehicle
before attempting to remove the winch
from the spare tire.
CAUTION
● Make sure safety cable is coiled above
spare tire when reinstalling spare
tire/wheel.
● When re-installing the spare tire under
the vehicle after use, be sure to secure
it with the tire stem facing down toward
the ground. If the spare tire is improp-
erly secured with the tire stem facing up
towards the bottom of the vehicle, there
is an increased risk of separating from
the vehicle in the event of crash which
may pose a hazard in traffic or risk of
injury to others.
Jacking up vehicle and removing the
damaged tire
WARNING
●Never get under the vehicle while it is
supported only by the jack. If it is nec-
essary to work under the vehicle, sup-
port it with safety stands.
● Use only the jack provided with your
vehicle to lift the vehicle. Do not use the
jack provided with your vehicle on other
vehicles. The jack is designed for lifting
only your vehicle during a tire change.

4. Lower the vehicle slowly until the tiretouches the ground. Then, with the wheel
nut wrench, tighten the wheel nuts securely
in the sequence illustrated (
A,B,C,D,
E) . Lower the vehicle completely.
WARNING
●Incorrect wheel nuts or improperly
tightened wheel nuts can cause the
wheel to become loose or come off.
This could cause an accident.
● Do not use oil or grease on the wheel
studs or nuts. This could cause the nuts
to become loose.
● Retighten the wheel nuts when the ve-
hicle has been driven for 600 miles
(1,000 km) (also in cases of a flat tire,
etc.) .
As soon as possible, tighten the wheel nuts
to the specified torque with a torque
wrench.
Wheel nut tightening torque: 83 ft-lb (113 N·m)
The wheel nuts must be kept tightened to
specification at all times. It is recom-
mended that wheel nuts be tightened to
specifications at each lubrication interval. Adjust tire pressure to the COLD pressure.
COLD pressure: After vehicle has been
parked for three hours or more or driven
less than 1 mile (1.6 km) .
COLD tire pressures are shown on the tire
and loading information label affixed to the
driver side center pillar.
5. Securely store the flat tire and jacking equip- ment in the vehicle.
6. Close the liftgate.
WARNING
● Always make sure that the spare tire
and jacking equipment are properly se-
cured after use. Such items can become
dangerous projectiles in an accident or
sudden stop.
● The spare tire is designed for emer-
gency use. See specific instructions un-
der the heading “Wheels and tires” in
the “Maintenance and do-it-yourself”
section of this manual. ●
When re-installing the spare tire under
the vehicle after use, be sure to secure
it with the tire stem facing down toward
the ground. If the spare tire is improp-
erly secured with the tire stem facing up
towards the bottom of the vehicle, there
is an increased risk of separating from
the vehicle in the event of crash which
may pose a hazard in traffic or risk of
injury to others.

If you have a flat tire, see “Flat tire” in the
“In case of emergency” section of this
manual.
TIRE PRESSURE
Tire Pressure Monitoring System
(TPMS)
This vehicle is equipped with the Tire
Pressure Monitoring System (TPMS) . It
monitors tire pressure of all tires except
the spare. When the low tire pressure
warning light is lit and the “Tire Pressure
Low – Add Air” warning appears in the
vehicle information display, one or more of
your tires is significantly under-inflated. If
equipped, the system also displays pres-
sure of all tires (except the spare tire) on
the display screen by sending a signal
from a sensor that is installed in each
wheel.
The TPMS will activate only when the
vehicle is driven at speeds above 16 MPH
(25 km/h). Also, this system may not de-
tect a sudden drop in tire pressure (for
example a flat tire while driving) .For more details, refer to “Low tire pres-
sure warning light” in the “Instruments and
controls” section and “Flat tire” in the “In
case of emergency” section.
Tire inflation pressure
Check the tire pressures (including the
spare) often and always prior to long dis-
tance trips. The recommended tire pres-
sure specifications are shown on the
F.M.V.S.S./C.M.V.S.S. certification label
or 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 objects
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.
The TPMS with Tire Inflation Indicator
provides visual and audible signals out-
side the vehicle for inflating the tires to the
recommended COLD tire pressure. For
more information, see “TPMS with Tire
Inflation Indicator” in the “Starting and
driving” section.
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 Rating
(GVWR) is located on the
F.M.V.S.S./C.M.V.S.S. certifica-
tion label. The vehicle weight ca-
pacity is indicated on the Tire and
Loading Information label. Do
not load your vehicle beyond this
capacity. Overloading your ve-
hicle may result in reduced tire
life, unsafe operating conditions
due to premature tire failure, or
unfavorable handling character-
istics and could also lead to a
serious accident. Loading be-
yond the specified capacity may
also result in failure of other ve-
hicle 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 “Important
Tire Safety Information” (US) or
“Tire Safety Information”
(Canada) in the Warranty Infor-
mation Booklet.

Checking tire pressure
1. Remove the valve stem cap from thetire.
2. Press the pressure gauge squarely onto the valve stem. Do not press too
hard or force the valve stem side-
ways, or air will escape. If the hissing
sound of air escaping from the tire is
heard while checking the pressure,
reposition the gauge to eliminate this
leakage.
3. Remove the gauge. 4. Read the tire pressure on the gauge
stem and compare to the specifica-
tion shown on the Tire and Loading
Information label.
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.Size Cold Tire Inflation

Federal law requires tire manufacturers to
place standardized information on the
sidewall of all tires. This information iden-
tifies and describes the fundamental
characteristics of the tire and also pro-
vides the tire identification number (TIN)
for safety standard certification. The TIN
can be used to identify the tire in case of a
recall.

2TIN (Tire Identification Number) for a
new tire (example: DOT XX XX XXX
XXXX)
1. DOT: Abbreviation for the “Depart- ment Of Transportation”. The symbol
can be placed above, below or to the
left or right of the Tire Identification
Number.
2. Two-digit code: Manufacturer’s identification mark.
3. Two-digit code: Tire size. 4. Three-digit code: Tire type code
(Optional) .
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 means the
31st week of 2003. If these numbers
are missing, then look on the other
sidewall of the tire.
3Tire ply composition and material
The number of layers or plies of rubber-
coated fabric in the tire. Tire manufactur-
ers also must indicate the materials in the
tire, which include steel, nylon, polyester,
and others.
4Maximum 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 in-
flation pressure.
5Maximum load rating
This number indicates the maximum load
in kilograms and pounds that can be car-
ried by the tire. When replacing the tires
on the vehicle, always use a tire that has
the same load rating as the factory in-
stalled tire.
6Term of “tubeless” or “tube type”
Indicates whether the tire requires an in-
ner tube (“tube type”) or not (“tubeless”) .
