TIRE PRESSURE

Tire Pressure Monitoring System
(TPMS)

WARNING

Radio waves could adversely affect electric
medical equipment. Those who use a pace-
maker should contact the electric medical
equipment manufacturer for the possible
influences before use.

This vehicle is equipped with the Tire Pres-
sure 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” warn-
ing appears in the vehicle information display,
one or more of your tires is significantly
under-inflated. If equipped, 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 (25 km/h).
Also, this system may not detect a sudden
drop in tire pressure (for example a flat tire
while driving).

For additional information, see “Low tire
pressure warning light” (P. 2-13), “Tire Pres-
sure Monitoring System (TPMS)” (P. 5-5) and
“Flat tire” (P. 6-3).

Tire inflation pressure

Check the tire pressures (including the spare)
often and always prior to long distance trips.
The recommended tire pressure specifica-
tions

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.

TPMS with Tire Inflation Indicator provides vi-
sual and audible signals outside the vehicle for
inflating the tires to the recommended COLD tire
pressure. For additional information, see “TPMS
with tire inflation indicator” (P. 5-7).

Incorrect tire pressure, including under infla-
tion, may adversely affect tire life and ve-
hicle handling.

WARNING

•

Improperly inflated tires can fail sud-
denly and cause an accident.

•

The

Gross

Vehicle

Weight

Rating

(GVWR) is located on the F.M.V.S.S./
C.M.V.S.S. certification label. The ve-
hicle weight capacity is indicated on the
Tire and Loading Information label. Do
not load your vehicle beyond this capac-
ity. Overloading your vehicle may result
in reduced tire life, unsafe operating con-
ditions due to premature tire failure, or
unfavorable

handling

characteristics

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 are at the specified level.

•

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.

Checking tire pressure

WARNING

•

Driving at high speeds, 100 mph
(160 km/h) or higher sustained
where it is legal to do so, can cause
tires to have excessive heat build
up, which may result in a tire fail-
ure causing loss of control, crash,
injuries or even death.

LDI3172

LDI0393

8-28

Do-it-yourself

•

Some high-speed rated tires re-
quire inflation pressure adjust-
ment for high-speed operation.
When speed limits and road condi-
tions allow vehicle driving at high
speeds, make sure tires are rated
to support high speed operation,
tires are in optimal conditions and
pressure is adjusted to correct
cold inflation pressure for high
speed operation.

•

If your vehicle is equipped with
P235/55RF19 or P255/45RF20
tire sizes, tires require adjustment
to the inflation pressure when
driving the vehicle at speeds of
100 mph (160 km/h) or higher
where it is legal to do so. Set the
cold inflation pressure to 36 psi
(250 kPa).

•

After vehicle high speed operation
has ended, readjust the tire pres-
sure to the recommended cold in-
flation pressure. For additional in-
formation, see "Checking tire
pressure" (P. 8-28).

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, reposition the gauge to
eliminate this leakage.

3. Remove the gauge.

4. Read the tire pressure on the

gauge stem and compare to the
specification 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 pres-
sure. 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.

8. Check the pressure when driving

the vehicle at speeds of 100 mph
(160 km/h) or higher where it is
legal to do so.

TIRE LABELING

Federal law requires tire manufactur-
ers to place standardized information
on the sidewall of all tires. This infor-
mation identifies and describes the
fundamental characteristics of the tire
and also provides the Tire Identifica-
tion Number (TIN) for safety standard
certification. The TIN can be used to
identify the tire in case of a recall.

TYPES OF TIRES

WARNING

•

When changing or replacing tires, be sure
all four tires are of the same type (i.e.,
Summer, All Season or Snow) and con-
struction. 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
specified by INFINITI could affect the
proper operation of the low tire pressure
warning system.

•

Always use tires of the same type, size,
brand, construction and tread pattern on
all four wheels. Failure to do so may re-
sult in a circumference difference be-
tween tires on the front and rear axles
which can cause the Vehicle Dynamic
Control (VDC) system to malfunction re-
sulting in personal injury or death, exces-
sive tire wear and may damage the
transmission, transfer case and differen-
tial gears.

•

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.

All-Wheel Drive (AWD) models

CAUTION

•

ONLY use spare tires specified for the
AWD model.

If excessive tire wear is found, it is recom-
mended that all four tires be replaced with
tires of the same size, brand, construction
and tread pattern. The tire pressure and
wheel alignment should also be checked and
corrected as necessary. It is recommended
that you visit an INFINITI retailer for this
service.
