6. Push the ignition switch to the“ACC”
position. Then turn the compressor
switch to the ON (−) position and inflate
the tire up to the pressure that is
specified on the tire and loading
information label affixed to the driver’s
side center pillar if possible, or to the
minimum of 26 psi (180 kPa). Turn the
air compressor off briefly in order to
check the tire pressure with the pres-
sure gauge.
If the tire is inflated to higher than the
specified pressure, lower the tire pres-
sure by releasing air with the pressure
release valve. NOTE:
The compressor tire pressure gauge
may show a pressure reading of 87 psi
(600 kPa) for about 30 seconds while
inflating the tire. The pressure gauge is
indicating the pressure inside the
sealant can. When the sealant has
been injected into the tire the pressure
gauge will drop and indicate actual tire
pressure.
WARNING
.
To avoid serious personal injury while
using the emergency tire puncture repair
kit:
—Securely tighten the compressor
hose to the tire valve. Failure to do
so can cause the sealant to spray
into the air and get into your eyes or
on the skin.
. Do not stand directly beside the da-
maged tire while it is being inflated
because of the risk of the rupture. If
there are any cracks or bumps, turn the
compressor off immediately.
If the tire pressure does not increase to 26 psi (180 kPa) within 10 minutes, the
tire may be seriously damaged and
the
tire cannot be repaired with this tire
repair kit. Contact an INFINITI retailer.
7. When the tire pressure is at the
specified amount, turn the air compres-
sor off. If the pressure cannot be
inflated to the specified amount, the
air compressor can be turned off at the
minimum of 26 psi (180 kPa). Remove
the power plug from the power outlet
and quickly remove the hose from the
tire valve. Attach the protective cap and
valve cap. Properly stow the emergency
tire puncture repair kit in the trunk.
CAUTION
To avoid serious personal injury when
stowing the emergency tire puncture repair
kit:
. Keep the sealant bottle screwed into the
compressor. Failure to do so can cause
the sealant to spray into the air and get
into your eyes or on the skin.
8. Immediately drive the vehicle for 10
minutes or 2 miles (3 km) at a speed of

Tire Pressure Monitoring System
(TPMS)
GUID-92F1DBE9-C4EF-4679-8E12-AEDD5231258DThis 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.2-12),“Tire Pressure
Monitoring System (TPMS)” (P.5-4) and
“Tire Pressure Monitoring System (TPMS)”
(P.6-2).
Tire inflation pressureGUID-1E5BCB99-CF5B-436E-822C-36E9EA89ED84Check 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 whendriven 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 pressureGUID-6180484A-6593-4643-801D-6889016CD8CA1.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.
