position before servicing drive belts. The en-
gine could rotate unexpectedly.
1. Visually inspect each belt for signs ofunusual wear, cuts, fraying or looseness.
If the belt is in poor condition or loose,
have it replaced or adjusted by an INFINITI
retailer.
2. Have the belts checked regularly for con- dition and tension in accordance with the
maintenance schedule in your “INFINITI
Service and Maintenance Guide”.WARNING

Tire wear and damage
WARNING
●Tires should be periodically in-
spected for wear, cracking, bulging or
objects caught in the tread. If exces-
sive 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 indica-
tors 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 tech-
nician, 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 injury. If it
is necessary to repair the spare tire,
contact an INFINITI retailer.
●For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety In-
formation” (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 “SPECIFICATIONS”
in the “9. Technical and consumer information”
section for recommended types and sizes of
tires and wheels.)
WARNING
● The use of tires other than those recom-
mended or the mixed use of tires of different
brands, construction (bias, bias-belted or ra-
dial), or tread patterns can adversely affect
the ride, braking, handling, ground clear-
ance, body-to-tire clearance, tire chain
clearance, speedometer calibration, head-
light aim and bumper height. Some of these
effects may lead to accidents and could re-
sult in serious personal injury.
SDI1663
Maintenance and do-it-yourself8-37

●If the wheels are changed for any reason,
always replace with wheels which have the
same off-set dimension. Wheels of a differ-
ent off-set could cause premature tire wear,
degrade vehicle handling characteristics
and/or interference with the brake
discs/drums. Such interference can lead to
decreased braking efficiency and/or early
brake pad/shoe wear. See “WHEELS AND
TIRES” in the “9. Technical and consumer
information” section of this manual for
wheel off-set dimensions.
● 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 re-
main on after 1 minute. Contact your INFINITI
retailer as soon as possible for tire replace-
ment and/or system resetting.
● Replacing tires with those not originally
specified by INFINITI could affect the proper
operation of the TPMS.
● Do not install a damaged or deformed wheel
or tire even if it has been repaired. Such
wheels or tires could have structural damage
and could fail without warning.
● The use of retread tire is not recommended. ●
For additional information regarding tires,
refer to “Important Tire Safety Information”
(US) or “Tire Safety Information” (Canada) in
the Warranty Information Booklet.
Four-wheel Drive (4WD) models
CAUTION
● Always use tires of the same type, size,
brand, construction (bias, bias-belted or ra-
dial), and tread pattern on all four wheels.
Failure to do so may result in a circumference
difference between tires on the front and
rear axles which will cause excessive tire
wear and may damage the transmission,
transfer case and differential gears.
● ONLY use spare tires specified for the 4WD
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 nec-
essary. Contact an INFINITI retailer.
Wheel balance
Unbalanced wheels may affect vehicle handling
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 balancing 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
INFINITI Warranty Information Booklet.
Care of wheels
See “CLEANING EXTERIOR” in the “7. Appear-
ance and care” section for details about care of
the wheels.
Spare tire
When a spare tire is mounted (TEMPORARY USE
ONLY or conventional), the TPMS will not func-
tion.

INSTALLING FRONT LICENSE PLATE VEHICLE LOADING INFORMATION
9-12Technical and consumer information

This vehicle is equipped with an Event Data
Recorder (EDR). The main purpose of an EDR is
to record, in certain crash or near crash-like
situations, such as an air bag deployment or
hitting a road obstacle, data that will assist in
understanding how a vehicle’s systems per-
formed. The EDR is designed to record data
related to vehicle dynamics and safety systems
for a short period of time, typically 30 seconds
or less. The EDR in this vehicle is designed to
record such data as:
●How various systems in your vehicle were
operating;
● Whether or not the driver and passenger
safety belts were buckled/fastened;
● How far (if at all) the driver was depressing
the accelerator and/or brake pedal; and,
● How fast the vehicle was traveling.
● Sounds are not recorded.
These data can help provide a better under-
standing of the circumstances in which crashes
and injuries occur. NOTE: EDR data are recorded by your vehicle
only if a nontrivial crash situation occurs; no
data are recorded by the EDR under normal
driving conditions and no personal data (e.g.
name, gender, age and crash location) are
recorded. However, other parties, such as law
enforcement, could combine the EDR data with
the type of personally identifying data routinely
acquired during a crash investigation.
To read data recorded by an EDR, special equip-
ment is required and access to the vehicle or
the EDR is needed. In addition to the vehicle
manufacturer and INFINITI retailer, other par-
ties, such as law enforcement, that have the
special equipment, can read the information if
they have access to the vehicle or the EDR. EDR
data will only be accessed with the consent of
the vehicle owner or lessee or as otherwise
required or permitted by law.
Genuine INFINITI Service Manual for this model
and prior models can be purchased. A genuine
INFINITI Service Manual is the best source of
service and repair information for your vehicle.
This manual is the same one used by the factory
trained technicians working at an INFINITI re-
tailer. Genuine INFINITI Owner’s Manual can
also be purchased.
