When performing any inspection or mainte-
nance work on your vehicle, always take care to
prevent serious accidental injury to yourself or
damage to the vehicle. The following are gen-
eral precautions which should be closely ob-
served.
WARNING
•Park the vehicle on a level surface, apply the
parking brake securely and block the
wheels to prevent the vehicle from moving.
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 en-
gine is hot. Always turn off the engine and
wait until it cools down.
•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 any jewelry, such as rings,
watches, etc. before working on your ve-
hicle.
•If you must run the engine in an enclosed
space such as a garage, be sure there is
proper ventilation for exhaust gases to es-
cape.
•Never get under the vehicle while it is sup-
ported by a jack.
•Keep smoking materials, flame and sparks
away from fuel and the battery.
•Never connect or disconnect either the bat-
tery or any transistorized component con-
nector while the ignition switch is in the ON
position.
•On gasoline engine models with the Multi-
port Fuel Injection system, the fuel filter and
fuel lines should be serviced by an INFINITI
retailer or qualified workshop because the
fuel lines are under high pressure even
when the engine is turned off.
•Your vehicle is equipped with an automatic
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 dis-
connect 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 transmission
related component harness connector dis-
connected 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 flu-
ids can hurt the environment. Always con-
form to local regulations for disposal of ve-
hicle 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 affect
your warranty coverage. If in doubt about any
servicing, it is recommended you have it done by
an INFINITI retailer.
MAINTENANCE PRECAUTIONS
8-2Do-it-yourself

3. Fix the protective plate to the underside ofthe battery without any overlap
2.
4. Fit the replacement battery in the vehicle.
REINITIALISATION PROCEDURE AFTER
BATTERY RECONNECTION
If the battery has been reconnected, check the
following items:
•Clock setting (if so equipped). For details,
see Clock in the2. Instruments and con-
trols section, or the separately provided
navigation system Owner’s Manual, or the
audio device descriptions in Audio system
(if equipped) in the4. Display screen,
heater and air conditioner, and audio sys-
tem section.
•Reset the desired radio stations to the preset
station buttons. For details, see the audio
device descriptions in the “4. Heater and air
conditioner, and audio system”.
JUMP-STARTING
If jump-starting is necessary, see Jump
starting in the6. In case of emergency sec-
tion. If the engine does not start by jump
starting, the battery may have to be replaced. It
is recommended that you visit an INFINITI re-
tailer for this service.
WARNING
Be sure the ignition switch is in the OFF posi-
tion before servicing drive belt. The engine
could rotate unexpectedly.
1. Visually inspect each belt for signs of un- usual wear, cuts, fraying or looseness. If the
belt is in poor condition or loose, have it
replaced or adjusted. It is recommended that
you visit an INFINITI retailer for this service.
2. Have the belts checked regularly for condi- tion and tension in accordance with the
maintenance schedule as shown in a sepa-
rately provided Warranty Information and
Maintenance booklet.

Confirm the following for the TPMS:
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 af-
fect the ride, braking, handling, VDC sys-
tem, ground clearance, body-to-tire clear-
ance, tire chain clearance, speedometer
calibration, headlight aim and bumper
height. Some of these effects may lead to
accidents and could result in serious per-
sonal injury.
•For 2WD models, if your vehicle was origi-
nally 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 per-
sonal 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,
affect the VDC system and/or interference
with the brake discs. Such interference canlead to decreased braking efficiency and/or
early brake pad wear. For additional infor-
mation on wheel off-set dimensions, refer to
Wheels and Tires
in the9. Maintenance
and Schedules section.
•When a replacement tire is mounted or a
wheel is replaced, the TPMS will not func-
tion and the low tire pressure warning light
will flash for approximately 1 minute. The
light will remain on after 1 minute. Contact
an 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.
•The TPMS sensor may be damaged if it is not
handled correctly. Be careful when handling
the TPMS sensor.
•When replacing the TPMS sensor, the ID
registration may be required. It is recom-
mended that you visit an INFINITI retailer for
ID registration.
•Do not use a valve stem cap that is not speci-
fied by INFINITI. The valve stem cap may
become stuck.
•Be sure that the valve stem caps are cor-
rectly fitted. Otherwise the valve may be clogged up with dirt and cause a malfunc-
tion or loss of pressure.
•Do not install a damaged or deformed wheel
or tire even if it has been repaired. Such
wheels or tires could have structural dam-
age and could fail without warning.
•The use of retread tires is not recom-
mended.
•For additional information regarding tires,
refer to
Important Tire Safety Information
(US) or Tire Safety Information (Canada) in
the Warranty Information Booklet.
Care of wheels
•Wash the wheels when washing the vehicle
to maintain their appearance.
•Clean the inner side of the wheels when the
wheel is changed or the underside of the
vehicle is washed.
•Do not use abrasive cleaners when washing
the wheels.
•Inspect wheel rims regularly for dents or
corrosion. Such damage may cause loss of
pressure or poor seal at the tire bead.

Also make sure that the vehicle is held securely
on a fairly steep hill when only the parking
brake is applied. If the parking brake needs
adjustment, it is recommended you visit an
INFINITI retailer for this service.
Seats
:
Check seat position controls such as seat ad-
justers, 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.
Seat belts
:
Check that all parts of the seat belt system (for
example, buckles, anchors, adjusters and re-
tractors) operate properly and smoothly, and
are installed securely. Check the belt webbing
for cuts, fraying, wear or damage.

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*
:
Except for maintenance free battery, check the
fluid level in each cell. It should be between the
“UPPER” and “LOWER” lines. Vehicles operated
in high temperatures or under severe condi-
tions 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 electronic ac-
cessories that consume 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 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.
Coolant level*
:
Check the coolant level when the engine is cold.
Engine drive belt(s)*
:
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
