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 precau-
tions which should be closely observed.
WARNING
●Park the vehicle on a level surface, ap-
ply the parking brake securely and
block the wheels to prevent the vehicle
from moving. Move the shift lever to P
(Park) .
● Be sure the ignition switch is in the OFF
or LOCK position when performing any
parts replacement or repairs.
● 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 remove any jewelry,
such as rings, watches, etc. before
working on your vehicle.
● Always wear eye protection whenever
you work on your vehicle. ●
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 posi-
tion and the engine is not running. To
avoid injury, always disconnect the
negative battery cable before working
near the fan.
● If you must run the engine in an en-
closed 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 neces-
sary to work under the vehicle, support
it with safety stands.
● Keep smoking materials, flame and
sparks away from the fuel tank and
battery.
●
Because the fuel lines on gasoline en-
gine models are under high pressure
even when the engine is off, it is recom-
mended that you visit an INFINITI retailer
for service of the fuel filter or fuel lines.
CAUTION
● Do not work under the hood while the
engine is hot. Turn the engine off and
wait until it cools down. ●
Avoid contact with used engine oil and
coolant. Improperly disposed engine
oil, engine coolant and/or other vehicle
fluids can damage the environment. Al-
ways conform to local regulations for
disposal of vehicle fluid.
● Never leave the engine or Continuously
Variable Transmission (CVT) related
component harnesses disconnected
while the ignition switch is in the ON
position.
● Never connect or disconnect the battery
or any transistorized component while
the ignition switch is in the ON position.

DRIVE BELT
Do-it-yourself8-13
●The original tires have built-in
tread wear indicators. When the
wear indicators 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 technician because
some tire damage may not be ob-
vious. Replace the tires as neces-
sary to prevent tire failure and
possible personal injury.
● Improper service of the spare tire
may result in serious personal in-
jury. If it is necessary to repair the
spare tire, it is recommended that
you visit an INFINITI retailer for
this service.
● For additional information re-
garding tires, refer to “Important
Tire Safety Information” (US) or
“Tire Safety Information”
(Canada) in the Warranty Infor-
mation Booklet.Replacing wheels and tires
When replacing a tire, use the same size, tread
design, speed rating and load carrying capacity
as originally equipped. For additional information,
refer to “Wheels and tires” in the “Technical and
consumer information” section of this manual.
WARNING
●The use of tires other than those recom-
mended 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, VDC system, ground clear-
ance, body-to-tire clearance, tire chain
clearance, speedometer calibration,
headlight aim and bumper height.
Some of these effects may lead to acci-
dents and could result in serious per-
sonal injury.
● For 2WD models, if your vehicle was
originally equipped with four tires that
were the same size and you are only
replacing two of the four 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 rea-
son, always replace with wheels which
have the same off-set dimension.
Wheels of a different off-set could
cause premature tire wear, degrade ve-
hicle handling characteristics, affect the
VDC system and/or interference with
the brake discs. Such interference can
lead to decreased braking efficiency
and/or early brake pad wear. For addi-
tional information on wheel off-set di-
mensions, refer to “Wheels and tires” in
the “Technical and consumer informa-
tion” section of this manual.
● Since the spare tire is not equipped with
the TPMS, when a spare tire is mounted
or a wheel is replaced, tire pressure will
not be indicated, 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. Have your tires replaced
and/or TPMS system reset as soon as
possible. It is recommended that you
visit an INFINITI retailer for this service.
● Replacing tires with those not originally
specified by INFINITI could affect the
proper operation of the TPMS.
Do-it-yourself8-33
Make sure that the secondary latch keeps the
hood from opening when the primary latch 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 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*: Check the pressure with a gauge often
and always prior to long distance trips. If neces-
sary, 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 bal-
ancing 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 Booklet.
Windshield: Clean the windshield on a regular
basis. Check the windshield at least every six
months for cracks or other damage. Have a dam-
aged windshield repaired by a qualified repair
facility.
Windshield wiper blades*: Check for cracks
or wear if they do not wipe properly.
Inside the vehicle
The maintenance items listed here should be
checked on a regular basis, such as when per-
forming scheduled maintenance, cleaning the ve-
hicle, 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. Brake pedal:
Check the pedal for smooth op-
eration. 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
vehicle checked immediately. It is recommended
that 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.
Continuously Variable Transmission (CVT)
P (Park) position mechanism: On a fairly
steep hill check that the vehicle is held securely
with the shift lever in the P (Park) position without
applying any brakes.
Parking brake: Check the parking brake opera-
tion regularly. The vehicle should be securely held
on a fairly steep hill with only the parking brake
applied. If the parking brake needs adjustment, it
is recommended that you visit an INFINITI retailer
for this service.
Seat belts: Check that all parts of the seat belt
system (for example, buckles, anchors, adjusters
and retractors) operate properly and smoothly,
and are installed securely. Check the belt web-
bing for cuts, fraying, wear or damage.
Seats: Check seat position controls such as
seat adjusters, seatback recliner, etc., to ensure
they operate smoothly and all latches lock se-

curely in every position. Check that the head
restraints/headrests move up and down
smoothly and the locks (if so equipped) hold
securely in all latched positions.
Steering wheel:Check for changes in the
steering system, such as excessive free play,
hard steering or strange noises.
Warning lights and chimes: Make sure all
warning lights and chimes are operating properly.
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. The
fluid should be at the bottom of the filler opening.
Vehicles operated in high temperatures or under
severe conditions require frequent checks of the
battery fluid level. NOTE:
Care should be taken to avoid situations
that can lead to potential battery discharge
and potential no-start conditions such as:
1. Installation or extended use of elec-
tronic accessories that consume bat-
tery power when the engine is not run-
ning (Phone chargers, GPS, DVD
players, etc.) .
2. Vehicle is not driven regularly and/or
only driven short distances.
In these cases, the battery may need to be
charged to maintain battery health.
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 the drive belts
are not 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. It is recommended that you
visit an INFINITI retailer for this service. For addi-
tional information, refer to “Exhaust gas (carbon
monoxide)” in the “Starting and driving” section of
this manual.
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 fuel fumes are evident,
check for the cause and have it corrected imme-
diately.
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.
9-4Maintenance and schedules
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 may 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, refer to the “Appear-
ance and care” section of this manual.
Windshield-washer fluid*: Check that there is
adequate fluid in the reservoir. The following descriptions are provided to give
you a better understanding of the scheduled
maintenance items that should be regularly
checked or replaced. The maintenance schedule
indicates at which mileage/time intervals each
item requires service.
In addition to scheduled maintenance, your ve-
hicle requires that some items be checked during
normal day-to-day operation. For additional infor-
mation, refer to “General maintenance” in this
section.
Items marked with
“*”are recommended by
INFINITI for reliable vehicle operation. You are not
required to perform maintenance on these items
in order to maintain the warranties which come
with your INFINITI. Other maintenance items and
intervals are required.
When applicable, additional information can be
found in the “Do-it-yourself” section of this
manual. NOTE:
INFINITI does not advocate the use of non-
OEM approved aftermarket flushing sys-
tems and strongly advises against perform-
ing these services on an INFINITI product.
