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.
● Use the correct jack-up points. Never
use any other part of the vehicle for jack
support.
● Never jack up the vehicle more than
necessary.
● Never use blocks on or under the jack. ●
Do not start or run the engine while
vehicle is on the jack. It may cause the
vehicle to move. This is especially true
for vehicles with limited slip
differentials.
● Do not allow passengers to stay in the
vehicle while it is on the jack.
● Never run the engine with a wheel(s) off
the ground. It may cause the vehicle to
move.
Always refer to the illustration for the correct
placement and jack-up points for your specific
vehicle model and jack type.
Carefully read the caution label attached to
the jack body and the following instruc-
tions. 1. Loosen each wheel nut one or two turns by turning counterclockwise with the wheel nut
wrench. Do not remove the wheel nuts
until the tire is off the ground. NOTE:
Before jacking up the vehicle, make sure
the ignition switch is placed in the OFF
position. If the vehicle is lifted up with the
ignition switch placed in the ON position
the auto-leveling suspension will become
disabled after 60 seconds. To reset the
auto-leveling suspension, cycle the igni-
tion switch ON/OFF one time.

Installing the spare tire
The spare tire is designed for emergency
use. See specific instructions under the
heading “Wheels and tires” in the “Mainte-
nance and do-it-yourself” section of this
manual.1. Clean any mud or dirt from the surface be- tween the wheel and hub.
2. Carefully put the spare tire on and tighten the wheel nuts finger tight.
3. With the wheel nut wrench, tighten wheel nuts alternately and evenly as illustrated until
they are tight. 4. Lower the vehicle slowly until the tire
touches the ground. Then, with the wheel
nut wrench, tighten the wheel nuts securely
in the sequence illustrated. Lower the ve-
hicle 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: 98 ft-lb (133 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.
After adjusting tire pressure to the COLD
tire pressure, the display of the tire pres-
sure information may show higher pres-
sure than the COLD tire pressure after the
vehicle has been driven more than 1 mile
(1.6 km) . This is because the tire pressure
increases as the tire temperature rises.
This does not indicate a system malfunc-
tion.
5. Securely store the flat tire and jacking equip- ment in the vehicle.

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. To start your engine with a booster battery, the
instructions and precautions below must be fol-
lowed.
If the battery of a vehicle equipped with
INFINITI Intelligent Key™ is discharged, the
ignition switch cannot be moved from the

cables to another vehicle, as in the case of
a discharged battery, and then the ignition
switch can be moved from the LOCK posi-
tion. Then, jump start the vehicle.
WARNING
●
If done incorrectly, jump starting can
lead to a battery explosion, resulting in
severe injury or death. It could also
damage your vehicle.
● Explosive hydrogen gas is always
present in the vicinity of the battery.
Keep all sparks and flames away from
the battery. ●
Do not allow battery fluid to come into
contact with eyes, skin, clothing or
painted surfaces. Battery fluid is a cor-
rosive sulfuric acid solution which can
cause severe burns. If the fluid should
come into contact with anything, imme-
diately flush the contacted area with
water.
● Keep battery out of the reach of
children.
● The booster battery must be rated at 12
volts. Use of an improperly rated battery
can damage your vehicle.

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, one or more of your
tires is significantly under-inflated. The
system also displays pressure 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
(26 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, “Tire pressure informa-
tion” in the “Monitor, climate, audio, phoneand voice recognition systems” section,
“Tire Pressure Monitoring System
(TPMS)” in the “Starting and driving” sec-
tion, and “Flat tire” in the “In case of emer-
gency” 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.
Incorrect tire pressure, including un-
der inflation, may adversely affect
tire life and vehicle handling.

Replacing wheels and tires
When replacing a tire, use the same size, tread
design, speed rating and load carrying capacity
as originally equipped. Recommended types and
sizes are shown in “Wheels and tires” in the
“Technical and consumer information” section of
this manual.
WARNING
●The use of tires other than those recom-
mended or the mixed use of tires of
different brands, construction (bias,
bias-belted or radial) , or tread patterns
can adversely affect the ride, braking,
handling, ground clearance, body-to-
tire clearance, tire chain clearance,
speedometer calibration, headlight aim
and bumper height. Some of these ef-
fects may lead to accidents and could
result in serious personal injury.
● 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 conditions and cause an acci-
dent and personal injury. ●
If the wheels are changed for any rea-
son, always replace with wheels which
have the same off-set dimension.
Wheels of a different off-set could
cause premature tire wear, degrade ve-
hicle handling characteristics and/or
interference with the brake
discs/drums. Such interference can
lead to decreased braking efficiency
and/or early brake pad/shoe wear. Re-
fer to “Wheels and tires” in the “Techni-
cal and consumer information” section
of this manual for wheel off-set
dimensions.
● 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 dealer 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 install a damaged or deformed
wheel or tire even if it has been re-
paired. Such wheels or tires could have
structural damage and could fail with-
out warning.
● The use of retread tires is not
recommended.
● For additional information regarding
tires, refer to “Important Tire Safety In-
formation” (US) or “Tire Safety Informa-
tion” (Canada) in the Warranty Informa-
tion Booklet.
Four-wheel drive models
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 dam-
age the transmission, transfer case and
differential gears.
