For descriptions specified for all-wheel drive
models, anAWDmark is placed at the begin-
ning of the applicable sections/items.
As with other vehicles with features for off-
road use, failure to operate all-wheel drive
models correctly may result in loss of control
or an accident. For additional information,
refer to “Driving safety precautions” in the
“Starting and driving” section of this
manual.
ON-PAVEMENT AND OFF-ROAD
DRIVING
This vehicle will handle and maneuver dif-
ferently from an ordinary passenger car
because it has a higher center of gravity
for off-road use. As with other vehicles
with features of this type, failure to op-
erate this vehicle correctly may result in
loss of control or an accident.
For additional information, refer to “On-
pavement and off-road driving
precautions”, “Avoiding collision and roll-
over” and “Driving safety precautions” in
the “Starting and driving” section of this
manual.

manual.
TIRE PRESSURE
Tire Pressure Monitoring System
(TPMS)
WARNING
Radio waves could adversely affect
electric medical equipment. Those
who use a pacemaker should contact
the electric medical equipment
manufacturer for the possible influ-
ences before use.
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
“Tire Pressure Low – Add Air” warning
appears in the vehicle information dis-
play, one or more of your tires is sig-
nificantly under-inflated. If equipped,
the system also displays pressure of all
tires (except the spare tire) on the dis- play 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, refer to
“Low tire pressure warning light” in the
“Instruments and controls” section,
“Tire Pressure Monitoring System
(TPMS)” in the “Starting and driving”
section and “Flat tire” in the “In case of
emergency” section of this manual.
Tire inflation pressure
Check the tire pressures (including the
spare) often and always prior to long
distance trips. The recommended tire
pressure specifications are shown on
the F.M.V.S.S./C.M.V.S.S. certifica-
tion label or the Tire and Loading In-
formation label under the “Cold Tire
Pressure” heading. The Tire and Load-
ing Information label is affixed to thedriver 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 mod-
erate speeds.
TPMS with Tire Inflation Indicator
provides visual and audible signals
outside the vehicle for inflating the
tires to the recommended COLD tire
pressure. For additional information,
refer to “TPMS with tire inflation indi-
cator” in the “Starting and driving” sec-
tion of this manual.
Incorrect tire pressure, including un-
der inflation, may adversely affect
tire life and vehicle handling.

Checking tire pressure
1. Remove the valve stem cap fromthe 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 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.

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.

Wheel nut tightening torque:83 ft-lb (113 N·m)
The wheel nuts must be kept tight-
ened to specifications at all times. It is
recommended that wheel nuts be
tightened to 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 spare tire in the tire rotation.
∙ For additional information re- garding tires, refer to “Important
Tire Safety Information” (US) or
“Tire Safety Information”
(Canada) in the Warranty Infor-
mation Booklet.
Tire wear and damage
1. Wear indicator
2. Location mark
WARNING
∙ Tires should be periodically in- spected for wear, cracking, bulg-
ing or objects caught in the tread.
If excessive wear, cracks, bulging
or deep cuts are found, the tire(s)
should be replaced. ∙ The original tires have built-in
tread wear indicators. When the
wear indicators are visible, the
tire(s) should be replaced.
∙ Tires degrade with age and use. Have tires, including the spare,
over 6 years old checked by a
qualified technician because some
tire damage may not be obvious.
Replace the tires as necessary to
prevent tire failure and possible
personal injury.
∙ Improper service of the spare tire may result in serious personal in-
jury. If it is necessary to repair the
spare tire, it is recommended that
you visit an INFINITI retailer for
this service.
∙ For additional information re- garding tires, refer to “Important
Tire Safety Information” (US) or
“Tire Safety Information”
(Canada) in the Warranty Infor-
mation Booklet.

∙ Do not use fuel that contains the octanebooster methylcyclopentadienyl manga-
nese tricarbonyl (MMT). Using fuel con-
taining MMT may adversely affect ve-
hicle performance and vehicle emissions.
Not all fuel dispensers are labeled to indi-
cate MMT content, so you may have to
consult your gasoline retailer for more
details. Note that Federal and California
laws prohibit the use of MMT in reformu-
lated gasoline.
∙ U.S. government regulations require ethanol dispensing pumps to be identi-
fied by a small, square, orange and black
label with the common abbreviation or
the appropriate percentage for that
region.
Gasoline specifications
INFINITI recommends using gasoline that
meets the World-Wide Fuel Charter
(WWFC) specifications where it is available.
Many of the automobile manufacturers de-
veloped this specification to improve emis-
sion control system and vehicle performance.
Ask your service station manager if the gaso-
line meets the WWFC specifications.
Reformulated gasoline
Some fuel suppliers are now producing refor-
mulated gasolines. These gasolines are spe-
cially designed to reduce vehicle emissions.
INFINITI supports efforts towards cleaner air
and suggests that you use reformulated
gasoline when available.
Gasoline containing oxygenates
Some fuel suppliers sell gasoline containing
oxygenates such as ethanol, MTBE and
methanol with or without advertising their
presence. INFINITI does not recommend the
use of fuels of which the oxygenate content
and the fuel compatibility for your INFINITI
cannot be readily determined. If in doubt, ask
your service station manager.
If you use oxygenate-blend gasoline, please
take the following precautions as the usage
of such fuels may cause vehicle performance
problems and/or fuel system damage.
∙ The fuel should be unleaded and have an
octane rating no lower than that recom-
mended for unleaded gasoline. ∙
If an oxygenate-blend other than
methanol blend is used, it should contain
no more than 15% oxygenate.
∙ If a methanol blend is used, it should con-
tain no more than 5% methanol (methyl
alcohol, wood alcohol). It should also
contain a suitable amount of appropri-
ate cosolvents and corrosion inhibitors.
If not properly formulated with appro-
priate cosolvents and corrosion inhibi-
tors, such methanol blends may cause
fuel system damage and/or vehicle per-
formance problems. At this time, suffi-
cient data is not available to ensure that
all methanol blends are suitable for use in
INFINITI vehicles.
If any driveability problems such as engine
stalling and difficult hot-starting are experi-
enced after using oxygenate-blend fuels, im-
mediately change to a non-oxygenate fuel or
a fuel with a low blend of MTBE.
Take care not to spill gasoline during refuel-
ing. Gasoline containing oxygenates can
cause paint damage.
