Two-Wheel Drive (FWD) models
CAUTION
NEVER tow automatic transmission (DCT)
models with the front wheels on the
ground or with all four wheels on the
ground (forwards or backwards), as this
may cause serious and expensive damage
to the transmission. If it is necessary to tow
the vehicle with the rear wheels raised, al-
ways use towing dollies under the front
wheels.
Four-Wheel Drive (4WD) models
INFINITI recommends that towing dollies be
used under the front or rear wheels when
towing your vehicle or the vehicle be placed
on a flatbed tow truck as illustrated.
CAUTION
Never tow 4WD models with any of the
wheels on the ground. Doing so will cause
serious and expensive damage to the
drivetrain.
Vehicle recovery (freeing a stuck
vehicle)
WARNING
To avoid vehicle damage, serious personal
injury or death when recovering a stuck ve-
hicle:
•Contact a professional towing service to
recover the vehicle if you have any ques-
tions regarding the recovery procedure.
•Tow chains or cables must be attached
only to main structural members of the
vehicle.
•Do not use the vehicle tie downs to tow
or free a stuck vehicle.
•Only use devices specifically designed
for vehicle recovery and follow the
manufacturer's instructions.
•Always pull the recovery device straight
out from the front of the vehicle. Never
pull at an angle.
•Route recovery devices so they do not
touch any part of the vehicle except the
attachment point.

When performing any inspection or mainte-
nance work on your vehicle, always take care
to prevent serious accidental injury to your-
self or damage to the vehicle. The following
are general precautions which should be
closely observed.
WARNING
•Park the vehicle on a level surface, apply
the parking brake securely and block the
wheels to prevent the vehicle from mov-
ing. Press the P (Park) button.
•Be sure the ignition switch is in the OFF
position when performing any parts re-
placement or repairs.
•Do not work under the hood while the
engine is hot. Always turn off the engine
and wait until it cools down.
•If you must work with the engine run-
ning, keep your hands, clothing, hair and
tools away from moving fans, belts and
any other moving parts.
•It is advisable to secure or remove any
loose clothing and any jewelry, such as
rings, watches, etc. before working on
your vehicle.
•If you must run the engine in an enclosed
space such as a garage, be sure there is
proper ventilation for exhaust gases to
escape.
•Never get under the vehicle while it is
supported by a jack.
•Keep smoking materials, flame and
sparks away from fuel and the battery.
•Never connect or disconnect either the
battery or any transistorized compo-
nent connector while the ignition switch
is in the ON position.
•On gasoline engine models with the
Multiport Fuel Injection system, the fuel
filter and fuel lines should be serviced by
an INFINITI retailer or qualified work-
shop because the fuel lines are under
high pressure even when the engine is
turned off.
•Your vehicle is equipped with an auto-
matic engine cooling fan. It may come on
at any time without warning, even if the
ignition switch is in the OFF position
and the engine is not running. To avoid
injury, always disconnect the negative
battery cable before working near the
fan.
•Always wear eye protection whenever
you work on your vehicle.
•Never leave the engine or the transmis-
sion related component harness connec-
tor disconnected while the ignition
switch is in the ON position.
•Avoid direct contact with used engine oil
and coolant. Improperly disposed engine
oil, engine coolant, and/or other vehicle
fluids can hurt the environment. Always
conform to local regulations for disposal
of vehicle fluids.
This “ 8. Do-it-yourself” section provides in-
structions regarding only those items which
are relatively easy for an owner to perform.
You should be aware that incomplete or im-
proper servicing may result in operating diffi-
culties or excessive emissions, and could af-
fect your warranty coverage.If in doubt
about any servicing, it is recommended you
have it done by an INFINITI retailer.

3. Lift the cover up and away from the bat-
tery.
NOTE
When installing the battery cover, remem-
ber to replace cables in their original posi-
tion.
MAINTENANCE FREE BATTERY
For a maintenance free battery it is not re-
quired to check the fluid level. However,
INFINITI recommends to visually check the
status of the green indicator
A(if so
equipped) periodically. If it is not visible, re-
place the battery as soon as possible.
MODELS WITH IDLE
STOP/START SYSTEM
•Ensure that the battery fitted is the special
battery that is enhanced with regard to the
charge-discharge capacity and life perfor-
mance. Avoid using any other battery for
the Idle Stop/Start System, as this may
cause early deterioration of the battery or
a malfunction of the Idle Stop/Start Sys-
tem. It is recommended that a Genuine
INFINITI battery is fitted. For more infor-
mation, it is recommended that you con-
tact an INFINITI retailer.
•If the battery terminal is disconnected (for
battery replacement, etc.) and then recon-
nected, there may be some delay before
the Stop/Start System reactivates.
BATTERY REPLACEMENT
It is recommended that a Genuine INFINITI
battery is fitted. It is recommended that you
visit an INFINITI retailer for this service.
Protective plate for battery
WARNING
Whenever the battery is replaced, always
have the protective plate underneath the
battery also reinstalled or replaced. If this
plate is not reinstalled/replaced, in the
NDI920Z

name molding that is higher or deeper than
the same molding on the other sidewall of the
tire, or (2) the outward facing sidewall of an
asymmetrical tire that has a particular side
that must always face outward when
mounted on a vehicle.
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
construction. 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 they may not match the po-
tential maximum vehicle speed. Never
exceed the maximum speed rating of the
tire.
•Always use tires of the same type, size,
brand, construction and tread pattern
on all four wheels. Failure to do so may
result in a circumference difference be-
tween tires on the front and rear axles
which can cause the Vehicle Dynamic
Control (VDC) system to malfunctionresulting in personal injury or death, ex-
cessive tire wear and may damage the
transmission, transfer case and differ-
ential gears.
•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.
CAUTION
ONLY use spare tires specified for the
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.
All season tires
INFINITI specifies all season tires on some
models to provide good performance all year,
including snowy and icy road conditions. All
season tires are identified by ALL SEASON
and/or M&S on the tire sidewall. Snow tires
have better snow traction than all seasontires and may be more appropriate in some
areas.
Summer tires
INFINITI specifies summer tires on some
models to provide superior performance on
dry roads. Summer tire performance is sub-
stantially reduced in snow and ice. Summer
tires do not have the tire traction rating M&S
on the tire sidewall.
If you plan to operate your vehicle in snowy or
icy conditions, INFINITI recommends the use
of snow or all season tires on all four wheels.
Snow tires
If snow tires are needed, it is necessary to
select tires equivalent in size and load rating
to the original equipment tires. If you do not,
it can adversely affect the safety and han-
dling of your vehicle.
Generally, snow tires have lower speed rat-
ings than factory equipped tires and may not
match the potential maximum vehicle speed.
Never exceed the maximum speed rating of
the tire. If you install snow tires, they must be
the same size, brand, construction and tread
pattern on all four wheels.
For additional traction on icy roads, studded
tires may be used. However, some U.S. states
and Canadian provinces prohibit their use.
Check local, state and provincial laws before
8-32Do-it-yourself
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
performed. 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.
•How fast the vehicle was traveling.
•Sounds are not recorded.
This data can help provide a better under-
standing of the circumstances in which
crashes and injuries occur.
NOTE: EDR data are recorded by your ve-
hicle only if a nontrivial crash situation occurs;
no data are recorded by the EDR under nor-
mal 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 EDRdata with the type of personally identifying
data routinely acquired during a crash inves-
tigation.
To read data recorded by an EDR, special
equipment is required and access to the ve-
hicle or the EDR is needed. In addition to the
vehicle manufacturer and INFINITI retailer,
other parties, such as law enforcement, that
have the special equipment, can read the in-
formation 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 Manuals for this
model year and prior 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 work-
ing at INFINITI retailers. Genuine INFINITI
Owner’s Manuals can also be purchased.
