CHANGING A FLAT TIRE
If you have a flat tire, follow the instructions
below.
Stopping the vehicle
1. Safely move the vehicle off the road andaway from traffic.
2. Turn on the hazard warning flashers.
3. Park on a level surface and apply the parking brake. Move the shift lever to the
P (Park) position.
4. Turn off the engine.
5. Raise the hood to warn other traffic, and to signal professional road assistance
personnel 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 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 traf-
fic is close to your vehicle. Wait for
professional road assistance.
MCE0001A
Blocking wheels
Place suitable blocksat both the front and
back of the wheel diagonally opposite the
flat tire to 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.

6-8In case of emergency
wheel nut wrench, tighten the wheel
nuts securely in the sequence illustrated.
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
vehicle 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: 80 ft-lb (108 N·m)
The wheel nuts must be kept tigh-
tened to specification at all times. It
is recommended that wheel nuts be
tightened to specifications at each
lubrication interval.
.Adjust tire pressure to the COLD pressure. COLD pressure:
After the 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
equipment in the vehicle.
6. Place the spare tire cover and the trunk floor carpeting over the damaged tire.
7. Close the trunk.
WARNING
. Always make sure that the spare tire
and jacking equipment are properly
secured after use. Such items can
become dangerous projectiles in an
accident or sudden stop.
. The T-type spare tire and small size
spare tire are designed for emergency

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 CHECK TIRE PRESSURE
warning appears in the vehicle information
display, one or more of your tires is sig-
nificantly under-inflated.
The TPMS will activate only when the
vehicle is driven at speeds above 16 MPH
(25 km/h). Also, this system may not detect
a sudden drop in tire pressure (for example a
flat tire while driving).
For more details, see “Low tire pressure
warning light” (P.2-14), “Tire Pressure Mon-
itoring System (TPMS)” (P.5-5) and “Tire
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 andLoading 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.
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 tire chain must be secured or removed to
prevent the possibility of whipping action
damage to the fenders or underbody. If
possible, avoid fully loading your vehicle
when using tire chains. In addition, drive at
a reduced speed. Otherwise, your vehicle
may be damaged and/or vehicle handling
and performance may be adversely affected.
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.

CHANGING WHEELS AND TIRES
Tire rotation
INFINITI recommends rotating the
tires every 5,000 miles (8,000 km).
(See “Flat tire” (P.6-3) 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 specification 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 re-
garding tires, refer to “Impor-
tant Tire Safety Information”
(US) or “Tire Safety Informa-
tion” (Canada) in the Warranty
Information Booklet.

they should be balanced as required.
Wheel balance service should be performed
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 Booklet.
Care of wheels
See “Cleaning exterior” (P.7-2) for details
about care of the wheels.
Spare tire (TEMPORARY USE
ONLY (T-type) spare tire)
Since the spare tire is not equipped with the
TPMS, when a spare tire is mounted (TEM-
PORARY USE ONLY or conventional), the
TPMS will not function.
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 possi-
ble tire or differential damage.
. Drive carefully while the TEMPOR-
ARY 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 pressure for stan-
dard tires, as indicated on the Tire
and Loading Information label. For
Tire and Loading Information label
location, see “Tire and loading infor-
mation label” (P.10-16).
. 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 appear.
. 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 a TEM-
PORARY USE ONLY spare tire. Tire
chains will not fit properly and may
cause damage to the vehicle.
. Because the TEMPORARY USE
ONLY spare tire is smaller than the
original tire, ground clearance is re-
duced. To avoid damage to the
vehicle, do not drive over obstacles.
Also do not drive the vehicle through
an automatic car wash since it may
get caught.
