tire/wheel on the front of the
vehicle. Doing so can damage
the vehicle or tire. Damage to
the tire may result in a sudden
loss of air pressure which may
cause loss of vehicle control in
some driving conditions and
cause a collision and personal
injury.
. Retighten the wheel nuts when
the vehicle has been driven for
600 miles (1,000 km) (also in
cases of a flat tire, etc.).
. For additional information re-
garding tires, refer to “Impor-
tant Tire Safety Information”
(US) or “Tire Safety Informa-
tion” (Canada) in the Warranty
Information Booklet.
After the ignition switch is placed in
the ON position, it may take a period
of time for the tire pressure to be
displayed in the vehicle information
display while the vehicle is driven.
Depending on the radio wave circum-
stance, tire pressure may not cor- rectly be displayed.

Tire wear and damage
WARNING
. Tires should be periodically in-
spected for wear, cracking, bul-
ging 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
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 perso-
nal injury. If it is necessary to
repair the spare tire, it is re-
commended you visit an
INFINITI retailer for this ser-
vice.
. For additional information re-
garding tires, refer to “Impor-
tant Tire Safety Information”
(US) or “Tire Safety Informa-
tion” (Canada) in the Warranty
Information Booklet.Replacing wheels and tires
When replacing a tire, use the same size,
tread design, speed rating and load carrying
capacity as originally equipped. (See “Speci-
fications” (P.10-11) for recommended types
and sizes of tires and wheels.)
After the ignition switch is placed in the ON
position, it may take a period of time for the
tire pressure to be displayed in the vehicle
information display while the vehicle is
driven. Depending on the radio wave circum-
stance, tire pressure may not correctly be
displayed.
WARNING
. The use of tires other than those
recommended or the mixed use of
tires of different brands, construc-
tion (bias, bias-belted, radial or run-
flat), or tread patterns can adversely
affect the ride, braking, handling,
ground clearance, body-to-tire clear-
ance, tire chain clearance, speed-
ometer calibration, headlight aim
and bumper height. Some of these
effects may lead to accidents and
could result in serious personal injury.
. For Two-Wheel Drive (2WD) models,
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 condi-
tions and cause an accident and
personal injury.
. If the wheels are changed for any
reason, always replace with wheels
which have the same off-set dimen-
sion. Wheels of a different off-set
could cause premature tire wear,
degrade vehicle handling character-
istics and/or interference with the
brake discs/drums. Such interference
can lead to decreased braking effi-
ciency and/or early brake pad/shoe
wear. See “Wheels and tires” (P.10-
12) of this manual for wheel off-set
dimensions.
. Since the spare tire is not equipped
with the TPMS, when a spare tire is
mounted or a wheel is replaced, 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. Have
your tires replaced and/or TPMS
system reset as soon as possible. It
is recommended you visit an INFINITI
retailer for these services.

.Operating in hot weather in stop-and-go
“rush hour” traffic.
. Extensive idling and/or low speed driving
for long distances, such as police, taxi or
door-to-door delivery use.
. Driving in dusty conditions.
. Driving on rough, muddy or salt spread
roads.
. Using a car-top carrier.
NOTE:
For vehicles operated in Canada, both
standard and severe maintenance items
should be performed at every interval.
OIL CONTROL SYSTEM (for
VR30DDTT engine models)
Your vehicle is equipped with oil control
system. It calculates engine oil and filter
change interval based on driving conditions.
Driving in severe conditions will shorten the
engine oil and filter change interval. When
the oil replacement indicator appears in the
vehicle information display, the engine oil
and filter need to be replaced. The following tables show the standard
maintenance schedule. Depending upon
weather and atmospheric conditions, vary-
ing road surfaces, individual driving habits
and vehicle usage, additional or more fre-
quent maintenance may be required.
After 120,000 miles (192,000 km)/144
months, continue maintenance at the same
mileage/time intervals.

NOTE:
(1) After 40,000 miles (64,000 km) or 48
months, inspect every 10,000 miles
(16,000 km) or 12 months. Replace the
drive belts if found damaged.
(2) If operating mainly in dusty conditions,
more frequent maintenance may be re-
quired.
(3) Periodic maintenance is not required.
(4) First replacement interval is 105,000
miles (168,000 km) or 84 months. After first replacement, replace every 75,000
miles (120,000 km) or 60 months.
(5) Use only Genuine NISSAN Long Life
Antifreeze/Coolant (blue) or equivalent
with proper mixture ratio of 50% anti-
freeze and 50% demineralized or distilled
water. Mixing any other type of coolant or
the use of non-distilled water may reduce
the life expectancy of the factory fill cool-
ant.
(6) If the oil replacement indicator is
displayed, change the engine oil and filteras soon as possible. After replacing the
engine oil, reset the display.
(7) Replace spark plug when the plug gap
exceeds 0.043 in (1.1 mm) even if within
specified replacement mileage.
(8) Periodic maintenance is not required.
However, if valve noise increases, inspect
valve clearance.
