is released.
When driving in areas using road salt or
other corrosive materials, 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 operating properly and
installed securely. Also check headlight
aim.
Road wheel nuts (lug nuts)*: When check-
ing 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 7,500 miles (12,000 km). If your
vehicle is equipped with different sized
tires in the front and rear, tires cannot be
rotated.
Tires*: Check the pressure with a gauge
often and always prior to long distance
trips. If necessary, adjust the pressure in
all tires, including the spare, 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 replaced due to
wear or age.
Tire, 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
normal highway speeds, wheel balancing
may be needed.
For additional information regarding tires,
refer to “Important Tire Safety Information”
(US) or “Tire Safety Information” (Canada)
in the INFINITI Warranty Information Book-
let.
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.
Windshield wiper blades*: Check for
cracks or wear if they do not wipe properly.
Inside the vehicleGUID-9BC72144-3F74-486E-818A-C3F8D037D67DThe maintenance items listed here should
be checked on a regular basis, such as
when performing periodic maintenance,
cleaning the vehicle, etc. Accelerator pedal:
Check the pedal for
smooth operation and make sure the pedal
does not catch or require uneven effort.
Keep the floor mat away from the pedal.
Automatic transmission P (Park) mechan-
ism: On a fairly steep hill, check that your
vehicle is held securely with the selector
lever in the P (Park) position 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, see an INFINITI retailer
immediately. Keep the floor mat away from
the pedal.
Brakes: Check that the brakes do not pull
the vehicle to one side when applied.
Parking brake: Check the parking brake
operation regularly. The vehicle should be
securely held on a fairly steep hill with only
the parking brake applied. If the parking
brake needs adjusted, see an INFINITI
retailer.
Seat belts: Check that all parts of the seat
belt system (for example, buckles, an-
chors, adjuster and retractors) operate
properly and smoothly, and are installed

8-6Maintenance and do-it-yourself
Underbody:The underbody is frequently
exposed to corrosive substances such as
those used on icy roads or to control dust.
It is very important to remove these
substances, otherwise rust will form on
the floor pan, frame, fuel lines and around
the exhaust system. At the end of winter,
the underbody should be thoroughly
flushed with plain water, being careful to
clean those areas where mud and dirt may
accumulate. For additional information,
see “Cleaning exterior” (P.7-2).
Windshield washer fluid*: Check that there
is adequate fluid in the reservoir.
GUID-DA5BC1C7-4A3F-402D-B20E-D7AF3C2C5866When performing any inspection or main-
tenance 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 mod-
els, move the shift lever to N (Neutral).
For automatic transmission 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 ignition switch is in the ON position.
. Never leave the engine or automatic
transmission related component har-
nesses disconnected 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
supported 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 auto-
matic 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 disconnect the negative
battery cable before working near the
fan.

GUID-5C044D87-071E-4DD5-85C9-155F3106646BThe engine cooling system is filled at the
factory with a pre-diluted mixture of 50%
Genuine NISSAN Long Life Antifreeze/Cool-
ant (blue) and 50% water to provide year-
round anti-freeze and coolant protection.
The antifreeze solution contains rust and
corrosion inhibitors. Additional engine
cooling system additives are not neces-
sary.
WARNING
.Never remove the radiator or coolant
reservoir cap when the engine is hot.
Wait until the engine and radiator cool
down. Serious burns could be caused by
high pressure fluid escaping from the
radiator. See precautions in “If your
vehicle overheats” (P.6-11) of this man-
ual.
. The radiator is equipped with a pressure
type radiator cap. To prevent engine
damage, use only a genuine NISSAN
radiator cap.
CAUTION
.Never use any cooling system additives
such as radiator sealer. Additives may
clog the cooling system and cause
damage to the engine, transmission
and/or cooling system.
. When adding or replacing coolant, be
sure to use only Genuine NISSAN Long
Life Antifreeze/Coolant (blue) or equiva-
lent. Genuine NISSAN Long Life Anti-
freeze/Coolant (blue) is pre-diluted to
provide antifreeze protection to −348F
(−378C). If additional freeze protection is
needed due to weather where you
operate your vehicle, add Genuine
NISSAN Long Life Antifreeze/Coolant
(blue) concentrate following the direc-
tions on the container. If an equivalent
coolant other than Genuine NISSAN Long
Life Antifreeze/Coolant (blue) is used,
follow the coolant manufacturer’s in-
structions to maintain minimum anti-
freeze protection to −348F (−378C). The
use of other types of coolant solutions
other than Genuine NISSAN Long Life
Antifreeze/Coolant (blue) or equivalent
may damage the engine cooling system. .
The life expectancy of the factory-fill
coolant is 105,000 miles (168,000 km)
or 7 years. Mixing any other type of
coolant other than Genuine NISSAN Long
Life Antifreeze/Coolant (blue), including
Genuine NISSAN Long Life Antifreeze/
Coolant (green), or the use of non-
distilled water will reduce the life
expectancy of the factory-fill coolant.
Refer to the INFINITI Service and Main-
tenance Guide for more details.

capacity depends on the oil tempera-
ture and drain time. Use these specifi-
cations for reference only. Always use
the dipstick to determine the proper
amount of oil in the engine.
10. Start the engine and check for leakage around the drain plug and the oil filter.
Correct as required.
11. Turn the engine off and wait more than 15 minutes. Check the oil level with the
dipstick. Add engine oil if necessary.

the clip in place.
d. Install the other bolts that hold the undercover in place. Be careful not
to strip the bolts or over-tighten
them. 2.
Lower the vehicle carefully to the
ground.
3. Dispose of waste oil and filter properly.
WARNING
. Prolonged and repeated contact with
used engine oil may cause skin cancer.
. Try to avoid direct skin contact with used
oil. If skin contact is made, wash
thoroughly with soap or hand cleaner
as soon as possible.
. Keep used engine oil out of reach of
children.
GUID-ABB7B99A-4CD8-484D-A111-E2B0D9730B70When checking or replacement is required,
we recommend an INFINITI retailer for
servicing.
CAUTION
.Use only Genuine NISSAN Matic S ATF.
Do not mix with other fluids.
. Using automatic transmission fluid other
than Genuine NISSAN Matic S ATF will

Replacing wheels and tiresGUID-4EF95767-87A1-46D1-823F-01023BAE60AAWhen replacing a tire, use the same size,
tread design, speed rating and load carry-
ing capacity as originally equipped. (See
“Specifications”(P.9-8) for recommended
types and sizes of tires and wheels.)
WARNING
. The use of tires other than those
recommended or the mixed use of tires
of different brands, construction (bias,
bias-belted or radial), or tread patterns
can adversely affect the ride, braking,
handling, ground clearance, body-to-tire
clearance, 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 conditions 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 dimension.
Wheels of a different off-set could cause
premature tire wear, degrade vehicle
handling characteristics and/or interfer-
ence with the brake discs/drums. Such
interference can lead to decreased brak-
ing efficiency and/or early brake pad/
shoe wear. See “Wheels and tires” (P.9-
9) 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 remain on after 1 minute.
Contact your 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.
. 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 tire is not recom-
mended.
. For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or“Tire Safety Infor-
mation” (Canada) in the Warranty Infor-
mation Booklet.All-Wheel Drive (AWD) modelsGUID-0EB56D0C-6EAC-46F4-9C56-5E4540701594
CAUTION
. Always use tires of the same type, size,
brand, construction (bias, bias-belted or
radial), 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
recommended that all four tires be re-
