wheel nuts alternately and evenly in the
sequence 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 as
illustrated. Lower the vehicle comple-
tely.
WARNING. Incorrect wheel nuts or improperly tigh-
tened 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 tightened
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

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
use. See specific instructions under the
heading “ Wheels and tires ” (P.8-33).

To start your engine with a booster battery,
the instructions and precautions below
must be followed.
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 pre-
sent 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
corrosive sulphuric acid solution which
can cause severe burns. If the fluid
should come into contact with anything,
immediately flush the contacted area
with water.
. Keep the 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. . Whenever working on or near a battery,
always wear suitable eye protectors (for
example, goggles or industrial safety
spectacles) and remove rings, metal
bands, or any other jewelry. Do not lean
over the battery when jump starting.
. Do not attempt to jump start a frozen
battery. It could explode and cause
serious injury.
. Your vehicle has an automatic engine
cooling fan. It could come on at any time.
Keep hands and other objects away from
it.

ground (if you do not use towing dollies)
or four wheels on the ground:
— Push the ignition switch to the ON
position and turn off all accessories.
— Always release the parking brake.
—
Move the transmission shift lever to
the N (Neutral) position.
— Observe the following restricted
towing speeds and distances for
manual transmission models only: .
Rear wheels on the ground:
Speed: Below 50 MPH (80 km/h)
Distance: Less than 50 miles (80
km) .
Four wheels on the ground:
Speed: Below 70 MPH (112 km/h)
Distance: Less than 500 miles

— If the speed or distance must
necessarily be greater, remove the
propeller shaft before towing to

INFINITI recommends that towing dollies be
used when towing your vehicle or the
vehicle be placed on a flat bed truck as
illustrated.
CAUTION Never tow AWD models with any of the
wheels on the ground as this may cause
serious and expensive damage to the
powertrain. VEHICLE RECOVERY (Freeing a stuck
vehicle) GUID-05991B38-9FB8-40E2-8907-B76FEB2747E1
WARNING . Stand clear of a stuck vehicle.
. Do not spin your tires at high speed. This
could cause them to explode and result
in serious injury. Parts of your vehicle
could also overheat and be damaged.

TIRE PRESSURE GUID-059CBC2D-BB1C-4DE2-B26E-A89198E003F1
Tire Pressure Monitoring System
(TPMS) GUID-54149EBD-6C2B-4EEC-AE1A-FDADBBA021B3
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 on the dot
matrix liquid crystal display, one or more
of your tires is significantly 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.2-15), “ Tire Pressure
Monitoring System (TPMS) ” (P.5-4) and
“ Tire Pressure Monitoring System (TPMS) ”
(P.6-2).
Tire inflation pressure GUID-FDC2587E-609D-4595-9387-574BE1BDEAC6
Check the pressure of the tires
(including the spare) often and al- ways prior to long distance trips. The
recommended tire pressure specifi-
cations 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
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
under 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. label. The vehicle
weight capacity is indicated on
the Tire and Loading Information
label. Do not load your vehicle
beyond this capacity. Overloading
your vehicle may result in reduced
tire life, unsafe operating condi-
tions due to premature tire failure,
or unfavorable handling character-
istics 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

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.

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
