During the normal day-to-day operation of
the vehicle, general maintenance should
be performed regularly as prescribed in
this section. If you detect any unusual
sounds, vibrations or smell, be sure to
check for the cause or have an INFINITI
retailer do it promptly. In addition, you
should notify an INFINITI retailer if you
think that repairs are required.
When performing any checks or mainte-
nance work, see“Maintenance precau-
tions” later in this section.
EXPLANATION OF MAINTENANCE
ITEMS
Additional information on the following
items with “*” is found later in this
section.
Outside the vehicle
The maintenance items listed here should
be performed from time to time, unless
otherwise specified.
Doors and engine hood: Check that all
doors and the engine hood, operate
properly. Also ensure that all latches lock
securely. Lubricate hinges, latches, latch
pins, rollers and links if necessary. 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 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 vehicle
The maintenance items listed here should
be checked on a regular basis, such as
when performing periodic maintenance,
cleaning the vehicle, etc.

GENERAL MAINTENANCE

8-4Maintenance and do-it-yourself
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 securely. Check the belt webbing for cuts,
fraying, wear or damage.
Seats:
Check seat position controls such as
seat adjusters, seatback recliner, etc. to
ensure they operate smoothly and that all
latches lock securely in every position.
Check that the head 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
steering 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
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). 12-volt battery*:
Check the fluid level in
each cell. It should be between the MAX
and MIN lines. Vehicles operated in high
temperatures or under severe condition
require frequent checks of the battery fluid
level.
NOTE:
Care should be taken to avoid situations
that can lead to potential 12-volt battery
discharge and potential no-start condi-
tions such as:
1. Installation or extended use of electro-
nic accessories that consume 12-volt
battery power when the engine is not
running (Phone chargers, GPS, DVD
players, etc.)
2. Vehicle is not driven regularly and/or
only driven short distances.
In these cases, the 12-volt battery may
need to be charged to maintain 12-volt
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 that no belt

ing the service plug can cause severe
burns or electric shock that may result in
serious injury or death.
. The hybrid system uses high voltage up
to 408V. The system can be hot while
and after starting. Be careful of both the
high voltage and the high temperature.
Obey the caution labels attached to the
vehicle.
. Park the vehicle on a level surface, apply
the parking brake securely and block the
wheels to prevent the vehicle from
moving. Move the shift selector to P
(Park).
. Be sure the ignition switch is in the OFF
or LOCK position when performing any
parts replacement or repairs.
. The engine can start at any time without
warning when the Hybrid System is in
the READY to drive mode. If you must
work with the Hybrid System in the
READY to drive mode, keep your hands,
clothing, hair and tools away from fans,
belts and any other parts that can move.
. 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 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.
. 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 the fuel tank and
battery.
CAUTION
.Do not work under the hood while the
engine is hot. Turn the hybrid system 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 damage the environment. Always
conform to local regulations for disposal
of vehicle fluid.
. Never leave the engine or the transmis-
sion related component harness connec-
tor 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.

TIRE PRESSURE
Tire Pressure Monitoring System
(TPMS)
This vehicle is equipped with the Tire
Pressure Monitoring System (TPMS). It
monitors tire pressure of all tires except
the spare. When the low tire pressure
warning light is lit and the CHECK TIRE
PRESSURE warning appears in the dot
matrix liquid crystal display, one or more
of your tires is significantly under-inflated.
The TPMS will activate only when the
vehicle is driven at speeds above 16 MPH
(25 km/h). Also, this system may not
detect a sudden drop in tire pressure (for
example a flat tire while driving).
For more details, see“Low tire pressure
warning light” in the“2. Instruments and
controls” section,“Tire Pressure Monitor-
ing System (TPMS) ”in the “5. Starting and
driving” section and “Tire Pressure Mon-
itoring System (TPMS) ”in the “6. In case
of emergency” section.
Tire inflation pressure
Check the pressure of the tires
(including the spare) often and al-
ways prior to long distance trips. The
recommended tire pressure specifi-
cations are shown on the Tire and
Loading Information label under the
“Cold Tire Pressure” heading. The
Tire and Loading Information label is
affixed to the driver side center pillar.
Tire pressures should be checked
regularly because:
.Most tires naturally lose air over time.
.Tires can lose air suddenly whendriven over potholes or other
objects or if the vehicle strikes a
curb while parking.
The tire pressures should be checked
when the tires are cold. The tires are
considered COLD after the vehicle
has been parked for 3 or more hours,
or driven less than 1 mile (1.6 km) at
moderate speeds.
WHEELS AND TIRES

SDI1575
Example
TIRE LABELING
Federal law requires tire manufac-
turers to place standardized informa-
tion on the sidewall of all tires. This
information identifies and describes
the fundamental characteristics of
the tire and also provides the tire
identification number (TIN) for safety
standard certification. The TIN can be
used to identify the tire in case of a
recall.
SDI1606
Example
*1Tire size (example: P215/60R16
94H)
1.P: The “P”indicates the tire is
designed for passenger vehicles.
(Not all tires have this informa-
tion.)
2.Three-digit number (215): This
number gives the width in milli-
meters of the tire from sidewall
edge to sidewall edge.
3.Two-digit number (60): This num-
ber, known as the aspect ratio, gives the tire’s ratio of height to
width.
4.R: The “R”stands for radial.
5.Two-digit number (16): This num-
ber is the wheel or rim diameter in
inches.
6.Two- or three-digit number (94):
This number is the tire’ s load
index. It is a measurement of
how much weight each tire can
support. You may not find this
information on all tires because it
is not required by law.
7.H: Tire speed rating. You should
not drive the vehicle faster than
the tire speed rating.

8-38Maintenance and do-it-yourself
Intended Outboard Sidewall is (1) the
sidewall that contains a whitewall,
bears white lettering or bears manu-
facturer, brand and/or model name
molding that is higher or deeper than
the same molding on the other side-
wall 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
(Example: 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 may not match the potential
maximum vehicle speed. Never exceed the maximum speed rating of the tire.
. Replacing tires with those not originally
specified by INFINITI could affect the
proper operation of the TPMS.
. For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or“Tire Safety Infor-
mation” (Canada) in the Warranty In-
formation Booklet.
All season tires
INFINITI specifies all season tires on some
models to provide good performance all
year, including snowy and icy road condi-
tions. All Season tires are identified by ALL
SEASON and/or M&S (Mud and Snow) on
the tire sidewall. Snow tires have better
snow traction than All Season tires 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
substantially 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 tires 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 handling of your vehicle.
Generally, snow tires will have lower speed
ratings 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 prohi-
bit their use. Check local, state and
provincial laws before installing studded
tires. Skid and traction capabilities of
studded snow tires, on wet or dry surfaces,
may be poorer than that of non-studded
snow tires.

TIRE CHAINS
Use of tire chains may be prohibited
according to location. Check the local laws
before installing tire chains. When instal-
ling tire chains, make sure they are the
proper size for the tires on your vehicle and
are installed according to the chain man-
ufacturer’s suggestions. Use only SAE
Class S chains. Class“S”chains are used
on vehicles with restricted tire to vehicle
clearance. Vehicles that can use Class “S”
chains are designed to meet the SAE
standard minimum clearances between
the tire and the closest vehicle suspension
or body component required to accommo-
date the use of a winter traction device (tire
chains or cables). The minimum clearances
are determined using the factory equipped
tire size. Other types may damage your
vehicle. Use chain tensioners when recom-
mended by the tire chain manufacturer to
ensure a tight fit. Loose end links of the
tire chain must be secured or removed to
prevent the possibility of whipping action
damage to the fenders or underbody. If
possible, avoid fully loading your vehicle
when using tire chains. In addition, drive at
a reduced speed. Otherwise, your vehicle
may be damaged and/or vehicle handling and performance may be adversely af-
fected.
Tire chains must be installed only on the
rear wheels and not on the front wheels.
Never install tire chains on a TEMPORARY
USE ONLY spare tire.
Do not use tire chains on dry roads. Driving
with tire chains in such conditions can
cause damage to the various mechanisms
of the vehicle due to some overstress.

WARNING
. Tires should be periodically in-
spected for wear, cracking, bul-
ging or objects caught in the
tread. If excessive 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
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
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.
