restraints move up and down smoothly and that
the locks (if so equipped) hold securely in all
latched positions.
Steering wheel: Check for changes in the steer-
ing conditions, such as excessive free play,
hard steering or strange noises.
Warning lights and chimes: Make sure that all
warning lights and chimes are operating prop-
erly.
Windshield defroster: Check that the air comes
out of the defroster outlets properly and in
sufficient quantity when operating the heater or
air conditioner.
Windshield wiper and washer*: Check that the
wipers and washer operate properly and that
the wipers do not streak.
Under the hood and vehicle The maintenance items listed here should be
checked periodically (for example, each time
you check the engine oil or refuel).
Battery*: Check the fluid level in each cell. It
should be between the MAX and MIN lines.
Vehicles operated in high temperatures or un-
der severe condition require frequent checks of
the battery fluid level. Brake fluid level*: Make sure that the brake
fluid level is between the MAX and MIN lines on
the reservoir.
Engine coolant level*: Check the coolant level
when the engine is cold.
Engine drive belts*: Make sure that no belt is
frayed, worn, cracked or oily.
Engine oil level*: Check the level after parking
the vehicle on a level spot and turning off the
engine. Wait more than 15 minutes for the oil to
drain back into the oil pan.
Exhaust system: Make sure there are no loose
supports, cracks or holes. If the sound of the
exhaust seems unusual or there is a smell of
exhaust fumes, immediately have the exhaust
system inspected by an INFINITI retailer. (See
“PRECAUTIONS WHEN STARTING AND DRIVING”
in the “5. Starting and driving” section for
exhaust gas (Carbon monoxide).)
Fluid leaks: Check under the vehicle for fuel, oil,
water or other fluid leaks after the vehicle has
been parked for a while. Water dripping from
the air conditioner after use is normal. If you
should notice any leaks or if gasoline fumes are
evident, check for the cause and have it cor-
rected immediately. Power steering fluid level* and lines: Check the
level when the fluid is cold, with the engine off.
Check the lines for proper attachment, leaks,
cracks, etc.
Radiator and hoses: Check the front of the
radiator and clean off any dirt, insects, leaves,
etc., that may have accumulated. Make sure the
hoses have no cracks, deformation, rot or loose
connections.
Underbody: The underbody is frequently ex-
posed to corrosive substances such as those
used on icy roads or to control dust. It is very
important to remove these substances, other-
wise rust will form on the floor pan, frame, fuel
lines and around the exhaust system. At the
end of winter, the underbody should be thor-
oughly flushed with plain water, being careful
to clean those areas where mud and dirt may
accumulate. For additional information, see
“CLEANING EXTERIOR” in the “7. Appearance
and care” section.
Windshield washer fluid*: Check that there is
adequate fluid in the reservoir.

When performing any inspection or maintenance
work on your vehicle, always take care to prevent
serious accidental injury to yourself 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 moving. For
manual transmission models, move the shift
lever to N (Neutral). For automatic transmis-
sion models, move the selector lever to P
(Park).
● Be sure the ignition switch is in the OFF or
LOCK position when performing any parts
replacement or repairs.
● Never connect or disconnect the battery or
any transistorized component while the ig-
nition switch is in the ON position.
● Never leave the engine or automatic trans-
mission related component harnesses dis-
connected while the ignition switch is in the
ON position.
● If you must work with the engine running,
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 remove any jewelry, such as
rings, watches, etc. before working on your
vehicle.
● Always wear eye protection whenever you
work 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 sup-
ported only by a jack. If it is necessary to
work under the vehicle, support it with
safety stands.
● Keep smoking materials, flame and sparks
away from fuel tank and the battery.
● Your vehicle is equipped with an automatic
engine cooling fan. It may come on at any
time without warning, even if the ignition
key is in the OFF position and the engine is
not running. To avoid injury, always discon-
nect the negative battery cable before work-
ing near the fan.
● The fuel filter or fuel lines should be serviced
by an INFINITI retailer because the fuel lines
are under high pressure even when the en-
gine is off. CAUTION● Do not work under the hood while the engine
is hot. Turn the engine off and wait until it
cools down.
● Avoid direct contact with used engine oil and
coolant. Improperly disposed engine oil,
coolant, and/or other vehicle fluids can dam-
age the environment. Always conform to lo-
cal regulations for disposal of vehicle fluid.
This “8. Maintenance and do-it-yourself” sec-
tion gives instructions regarding only those
items which are relatively easy for an owner to
perform.
A genuine INFINITI Service Manual is also avail-
able. (See “OWNER’S MANUAL/SERVICE
MANUAL ORDER INFORMATION” in the “9. Tech-
nical and consumer information” section.)
You should be aware that incomplete or im-
proper servicing may result in operating diffi-
culties or excessive emissions, and could affect
your warranty coverage. If in doubt about any
servicing, we recommend that it be done by an
INFINITI retailer.MAINTENANCE PRECAUTIONS

●
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. ● 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.
All-Wheel Drive (AWD) 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 AWD
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 (TEMPORARY USE ONLY
(T-type) spare tire) Observe the following precautions if the T-type
spare tire must be used, otherwise your vehicle
could be damaged or involved in an accident. WARNING● The T-type spare tire should be used for
emergency use. It should be replaced with
the standard tire at the first opportunity to
avoid possible tire or differential damage.
● Drive carefully while the TEMPORARY USE
ONLY spare tire is installed. Avoid sharp
turns and abrupt braking while driving.
● Periodically check spare tire inflation pres-
sure. Always keep the pressure of the TEM-
PORARY USE ONLY spare tire at 60 psi (420
kPa, 4.2 bar). Always keep the pressure of
the full size spare tire (if so equipped) at the
recommended pressure for standard tires,
as indicated on the Tire and Loading Infor-
mation label. For Tire and Loading Informa-
tion label location, see “Tire and Loading
Information label” in the index of this
manual.
● With the TEMPORARY USE ONLY spare tire
installed do not drive your vehicle at speeds
faster than 50 MPH (80 km/h).
● When driving on roads covered with snow or
ice, the TEMPORARY USE ONLY spare tire
should be used on the front wheels and origi-
nal tire used on the rear wheels (drive
wheels). Use tire chains only on the two rear
original tires.

This vehicle is equipped with an Event Data Re-
corder (EDR). The main purpose of an EDR is to
record, in certain crash or near crash-like situa-
tions, such as an air bag deployment or hitting a
road obstacle, data that will assist in under-
standing 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; 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 situa-
tion 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 rou-
tinely 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 manu-
facturer and INFINITI retailer, other parties, such
as law enforcement, that have the special equip-
ment, can read the information if they have ac-
cess 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 per-
mitted by law. A genuine INFINITI Service Manual is the best
source of service and repair information for your
vehicle. Filled with wiring diagrams, illustra-
tions and step-by-step diagnostic and adjust-
ment procedures, this manual is the same one
used by the factory trained technicians working
at an INFINITI retailer. Also available are genu-
ine INFINITI Owner’s Manuals, and genuine
INFINITI Service and Owner’s Manuals for older
INFINITI models.
