brake pad wear. For additional informa-
tion on wheel offset dimensions, refer to
"Wheels and Tires" in the "9. Mainte-
nance and Schedules" section.
•When a replacement tire is mounted or a
wheel is replaced, the TPMS will not
function and the low tire pressure warn-
ing light will flash for approximately 1
minute. The light will remain on after 1
minute. Contact an INFINITI retailer as
soon as possible for tire replacement
and/or system resetting.
•Replacing tires with those not originally
specified by INFINITI could affect the
proper operation of the TPMS.
•The TPMS sensor may be damaged if it
is not handled correctly. Be careful when
handling the TPMS sensor.
•When replacing the TPMS sensor, the ID
registration may be required. It is rec-
ommended that you visit an INFINITI re-
tailer for ID registration.
•Do not use a valve stem cap that is not
specified by INFINITI. The valve stem
cap may become stuck.
•Be sure that the valve stem caps are cor-
rectly fitted. Otherwise the valve may be clogged up with dirt and cause a mal-
function or loss of pressure.
•Do not install a damaged or deformed
wheel or tire even if it has been repaired.
Such wheels or tires could have struc-
tural damage and could fail without
warning.
•The use of retread tires is not recom-
mended.
•For additional information regarding
tires, refer to "Important Tire Safety In-
formation" (US) or "Tire Safety Infor-
mation" (Canada) in the Warranty In-
formation Booklet.
Care of wheels
•Wash the wheels when washing the ve-
hicle to maintain their appearance.
•Clean the inner side of the wheels when
the wheel is changed or the underside of
the vehicle is washed.
•Do not use abrasive cleaners when wash-
ing the wheels.
•Inspect wheel rims regularly for dents or
corrosion. Such damage may cause loss of
pressure or poor seal at the tire bead.
•INFINITI recommends waxing the road
wheels to protect against road salt in ar-
eas where it is used during winter.
WHEEL BALANCE
Unbalanced wheels may affect vehicle han-
dling and tire life. Even with regular use,
wheels can get out of balance. Therefore,
they should be balanced as required.
Wheel balance service should be performed
with the wheels off the vehicle. Spin balanc-
ing the wheels on the vehicle could lead to
mechanical damage.
For additional information regarding tires,
refer to "Important Tire Safety Information"
(US) or "Tire Safety Information" (Canada)
in the Warranty Information Booklet.

primary latch is released. When driving in ar-
eas using road salt or other corrosive materi-
als, check lubrication frequently.
Lights*:
Clean the headlights on a regular basis. Make
sure that the headlights, stop lights, tail lights,
turn signal lights, and other lights are all op-
erating properly and installed securely. Also
check the aim of the headlights.
Road wheel nuts (lug nuts)*:
When checking the tires, make sure no wheel
nuts are missing, and check for any loose
wheel nuts. Tighten if necessary.
Tire rotation*:
Tires should be rotated every 5,000 miles
(8,000 km). Tires marked with directional
indicators can only be rotated between front
and rear. Make sure that the directional indi-
cators point in the direction of wheel rotation
after the tire rotation is completed.
Tires*:
Check the pressure with a gauge often and
always prior to long distance trips. Adjust the
pressure in all tires to the pressure specified.
Check carefully for damage, cuts or excessive
wear.Tire Pressure Monitoring System (TPMS)
transmitter components:
Replace the TPMS transmitter grommet seal,
valve core and cap when the tires are re-
placed due to wear or age.
Wheel alignment and balance:
If the vehicle should pull to either side while
driving on a straight and level road, or if you
detect uneven or abnormal tire wear, there
may be a need for wheel alignment.
If the steering wheel or seat vibrates at nor-
mal highway speeds, wheel balancing may be
needed.
For additional information regarding tires, re-
fer to “Important Tire Safety Information”
(US) or “Tire Safety Information” (Canada) in
the INFINITI Warranty Information Booklet.
Windshield:
Clean the windshield on a regular basis.
Check the windshield at least every six
months for cracks or other damage. Have a
damaged windshield repaired by a qualified
repair facility.
Wiper blades*:
Check for cracks or wear if not functioning
correctly. Replace as necessary.Inside the vehicle
The maintenance items listed here should be
checked on a regular basis, such as when
performing scheduled maintenance, cleaning
the vehicle, etc.
Accelerator pedal:
Check the pedal for smooth operation and
make sure that the pedal does not catch or
require uneven effort. Keep the floor mat
away from the pedal.
Automatic transmission P (Park) mecha-
nism:
On a fairly steep hill, check that your vehicle is
held securely when P (Park) has been acti-
vated, without applying any brakes.
Brake pedal*:
Check the pedal for smooth operation. If the
brake pedal suddenly goes down further than
normal, the pedal feels spongy or the vehicle
seems to take longer to stop, have your ve-
hicle checked immediately. It is recommended
you visit an INFINITI retailer for this service.
Keep the floor mat away from the pedal.
Brakes:
Check that the brakes do not pull the vehicle
to one side when applied.
Maintenance and Schedules9-3

Propeller shaft(s):
Check for damage, looseness, and grease
leakage. (4WD/AWD).
Steering gear and linkage, axle and suspen-
sion parts, drive shaft boots:
Check for damage, looseness, and leakage of
oil or grease. Under severe driving conditions,
inspect more frequently
Tire rotation:
Tires should be rotated every 5,000 miles
(8,000 km) according to the instructions un-
der "Tire rotation*" earlier in this section.
When rotating tires, check for damage and
uneven wear. Replace if necessary.
Transmission fluid/oil, differential oil,
transfer case oil:
Visually inspect for signs of leakage at speci-
fied intervals.To ensure smooth, trouble-free, safe and
economical driving, INFINITI provides two
maintenance schedules that may be used,
depending upon the conditions in which you
usually drive. These schedules contain both
distance and time intervals, up to 120,000
miles (192,000 km)/144 months. For most
people, the odometer reading will indicate
when service is needed. However, if you drive
very little, your vehicle should be serviced at
the regular time intervals shown in the sched-
ule.
After 120,000 miles (192,000 km)/144
months, continue maintenance at the same
mileage/time intervals.
ADDITIONAL MAINTENANCE
ITEMS FOR SEVERE OPERATING
SYSTEMS
Additional maintenance items for severe op-
erating conditions; should be performed on
vehicles that are driven under especially de-
manding conditions. Additional maintenance
items should be performed if you primarily
operate your vehicle under the following con-
ditions:
•Repeated short trips of less than 5 miles in
normal temperatures or less than 10 miles
in freezing temperatures.
•Stop-and-go traffic in hot weather or low
speed driving for long distances.
•Driving in dusty conditions or on rough,
muddy or salt-spread roads.
•Towing a trailer, or using a camper or car-
top carrier.
OIL CHANGE MONITOR
This vehicle is equipped with oil change moni-
tor. It calculates engine oil and filter change
interval base on driving conditions. Driving in
severe conditions will shorten the engine oil
and filter change interval. When the Engine
Oil – Service Due Now warning appears in
the vehicle information display, the engine oil
and filter need to be replaced.
NOTE
For vehicles operated in Canada, both stan-
dard and severe maintenance items should
be performed at every interval.
MAINTENANCE SERVICE
MESSAGES
The maintenance service interval display in-
forms you of the next service due date.
NOTE
The maintenance service interval display
does not show any information on the engine
oil level.
MAINTENANCE SCHEDULES
Maintenance and Schedules9-7

•For frequent operation in mountainous
terrain or on poor road surfaces
•If the engine is often left idling for long
periods
In these or similar operating conditions, have,
for example, the air filter, engine oil and oil
filter changed more frequently. The tires must
be checked more frequently if the vehicle is
operated under increased loads. Further in-
formation can be obtained at an INFINITI
retailer.

WHEELS AND TIRES
10-8Technical information

Before driving a loaded vehicle, confirm that
you do not exceed the Gross Vehicle Weight
Rating (GVWR) or the Gross Axle Weight
Rating (GAWR) for your vehicle. (See "Mea-
surement of weights" later in this section.)
Also check tires for proper inflation pres-
sures. See the Tire and Loading Information
label.
LOADING TIPS
•The GVW must not exceed GVWR or
GAWR as specified on the F.M.V. S.S./
C.M.V.S.S. certification label.
•Do not load the front and rear axle to the
GAWR. Doing so will exceed the GVWR.
WARNING
•Properly secure all cargo to help prevent
it from sliding or shifting. Do not place
cargo higher than the seatbacks. In a
sudden stop or collision, unsecured
cargo could cause personal injury.
•Do not load your vehicle any heavier
than the GVWR or the maximum front
and rear GAWRs. If you do, parts of your
vehicle can break, tire damage could oc-
cur, or it can change the way your ve-
hicle handles. This could result in loss of
control and cause personal injury.
•Overloading could not only shorten the
life of your vehicle and the tires, but also
could cause unsafe vehicle handling and
longer braking distances. This may
cause a premature tire failure which
could result in a serious accident and
personal injury. Failures caused by over-
loading are not covered by the vehicle's
warranty.
MEASUREMENT OF WEIGHTS
Secure loose items to prevent weight shifts
that could affect the balance of your vehicle.
When the vehicle is loaded, drive to a scale
and weigh the front and the rear wheels
separately to determine axle loads. Individual
axle loads should not exceed either of the
gross axle weight ratings (GAWR). The total
of the axle loads should not exceed the gross
vehicle weight rating (GVWR). These ratings
are given on the vehicle certification label. If
weight ratings are exceeded, move or remove
items to bring all weights below the ratings. Your vehicle was designed to be used to carry
passengers and luggage
CAUTION
Do not tow a trailer with your vehicle.
TRAILER TOWING
10-16Technical information

DOT (Department Of Transportation) Qual-
ity Grades: All passenger car tires must con-
form to federal safety requirements in addi-
tion to these grades.
Quality grades can be found where appli-
cable on the tire sidewall between tread
shoulder and maximum section width. For
example:
Treadwear 200 Traction AA Temperature A
TREADWEAR
The treadwear grade is a comparative rating
based on the wear rate of the tire when
tested under controlled conditions on a
specified government test course. For ex-
ample, a tire graded 150 would wear one and
one-half (1 1/2) times as well on the govern-
ment course as a tire graded 100. The rela-
tive performance of tires depends upon ac-
tual conditions of their use, however, and
may depart significantly from the norm due
to variations in driving habits, service prac-
tices and differences in road characteristics
and climate.
TRACTION AA, A, B AND C
The traction grades, from highest to lowest,
are AA, A, B and C. Those grades represent
the tire’s ability to stop on wet pavement as
measured under controlled conditions on
specified government test surfaces of as-
phalt and concrete. A tire marked C may have
poor traction performance.
WARNING
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration,
cornering, hydroplaning, or peak traction
characteristics.
TEMPERATURE A, B AND C
The temperature grades A (the highest), B,
and C, representing the tire’s resistance to
the generation of heat and its ability to dissi-
pate heat when tested under controlled con-
ditions on a specified indoor laboratory test
wheel. Sustained high temperature can cause
the material of the tire to degenerate and
reduce tire life, and excessive temperature
can lead to sudden tire failure. The grade C
corresponds to a level of performance which
all passenger car tires must meet under the
Federal Motor Vehicle Safety Standard No.
109. Grades B and A represent higher levelsof performance on the laboratory test wheel
than the minimum required by law.
WARNING
The temperature grade for this tire is es-
tablished for a tire that is properly inflated
and not overloaded. Excessive speed,
under-inflation, or excessive loading, ei-
ther separately or in combination, can
cause heat build-up and possible tire
failure.
