Parking brakeCheck 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,
see an INFINITI retailer.
Seats Check seat position controls such as seat
adjusters, seatback recliner, etc. to ensure they
operate smoothly and all latches lock securely 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.
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.
Steering wheel Check for changes in the steer-
ing system, such as excessive freeplay, hard
steering or strange noises.
Warning lights and chimes Make sure all
warning lights and chimes are operating properly.
Windshield wiper and washer* Check that
the wipers and washer operate properly and that
the wipers do not streak. Windshield defroster
Check that the air
comes out of the defroster outlets properly and in
sufficient quantity when operating the heater or
air conditioner.
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* Except for maintenance-free
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
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 electronic
accessories 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 MIN and MAX lines on the
reservoir.
Engine coolant level* Check the coolant level
when the engine is cold. Make sure that the
coolant level is
between the MAXandMIN lines on the reser-
voir.
Inverter coolant level* Check the coolant level
when the inverter is cold. Make sure the coolant
level is between the “MAX” and “MIN” lines on the
reservoir.
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 surface with the engine off.
Wait more than 10 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 the
carbon monoxide warning in the “Starting and
driving” section of this manual.
Maintenance and do-it-yourself8-3
Fluid leaksCheck 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 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.
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 from the
underbody, otherwise rust may form on the floor
pan, frame, fuel lines and exhaust system. At the
end of winter, the underbody should be thor-
oughly flushed with plain water, in those areas
where mud and dirt may have accumulated. See
the “Appearance and care” section of this
manual.
Windshield-washer fluid* Check that there is
adequate fluid in the reservoir.

NOTE:
Hybrid system engine compartment cov-
er(s) removed for clarity.The inverter cooling system is filled at the factory
with a pre-diluted mixture of 50% Genuine
NISSAN Long Life Antifreeze/Coolant (blue) and
50% water to provide year-round anti-freeze and
coolant protection. The anti-freeze solution con-
tains rust and corrosion inhibitors. Additional in-
verter cooling system additives are not neces-
sary.WARNING
●
Never remove the coolant reservoir cap
when the engine and inverter are hot.
Wait until the engine and inverter cool
down. Serious burns could be caused
by high pressure fluid escaping from
the reservoir.
● The inverter reservoir is equipped with a
pressure type cap. To prevent engine
and inverter damage, use only a genu-
ine NISSAN inverter reservoir cap.
CAUTION
● Never use any additives in the coolant
such as radiator sealer in the cooling
system. This may cause damage to elec-
trical equipment such as the motor and
inverter, as well as the engine and
transmission. ●
When adding or replacing coolant, be
sure to use only a Genuine NISSAN
Long Life Antifreeze/Coolant (blue) or
equivalent. Genuine NISSAN Long Life
Antifreeze/Coolant (blue) is pre-diluted
to provide antifreeze protection to -34°
F (-37° C) . If additional antifreeze pro-
tection is needed due to weather where
you operate your vehicle, add Genuine
NISSAN Long Life Antifreeze/Coolant
(blue) . The use of other types of coolant
solutions other than Genuine NISSAN
Long Life Antifreeze/Coolant (blue) or
equivalent, may damage the inverter
cooling system.
● The life expectancy of the factory-fill
coolant is 125,000 miles (200,000 km) or
15 years. Mixing any other type of cool-
ant other than Genuine NISSAN Long
Life Antifreeze/ Coolant (blue) , includ-
ing Genuine NISSAN Long Life
Antifreeze/ Coolant (green) , or the use
on non-distilled water will reduce the
life expectancy of factory-fill coolant.
Refer to the INFINITI Service and Main-
tenance Guide for more details.

CAUTION
Be careful not to burn yourself. The engine
oil may be hot.
5. Wipe the engine oil filter sealing surface with a clean rag.
CAUTION
●Be sure to remove any old gasket
material remaining on the sealing
surface of the engine. Failure to do
so could lead to an oil leak and en-
gine damage.
● The dipstick must be inserted in
place to prevent oil spillage from the
dipstick hole when filling the engine
with oil.
6. Coat the gasket on the new filter with clean engine oil.
7. Screw on the oil filter until a slight resistance is felt, then tighten an additional 2/3 turn.
8. Start the engine and check for leakage around the oil filter. Correct as required. 9. Turn the engine off and wait more than
10 minutes. Check the oil level. Add engine
oil if necessary. ●
Keep the 12–volt battery surface clean and
dry. Clean the battery with a solution of bak-
ing soda and water.
● Make certain the terminal connections are
clean and securely tightened.
● If the vehicle is not to be used for 30 days or
longer, disconnect the negative (-) battery
terminal cable to prevent discharge.
12-VOLT BATTERY
Maintenance and do-it-yourself8-9
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
accessories 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.
WARNING
●Do not expose the 12–volt battery to
flames, an electrical spark or a ciga-
rette. Hydrogen gas generated by the
12–volt battery is explosive. Explosive
gases can cause blindness or injury. Do
not allow battery fluid to contact your
skin, eyes, fabrics or painted surfaces.
Sulfuric acid can cause blindness or in-
jury. After touching a 12–volt battery or
battery cap, do not touch or rub your
eyes. Thoroughly wash your hands. If
the acid contacts your eyes, skin or
clothing, immediately flush with water
for at least 15 minutes and seek medical
attention. ●
If the 12-volt battery needs to be re-
placed, use a battery of the same de-
sign. Using the wrong battery can cause
hydrogen gas to build up in the vehicle ,
which could lead to explosion and per-
sonal injury.
● When working on or near a 12–volt bat-
tery, always wear suitable eye protec-
tion and remove all jewelry.
● Battery posts, terminals and related ac-
cessories contain lead and lead com-
pounds. Wash hands after handling.
● Keep 12–volt battery out of the reach of
children.CAUTION
● Do not ground accessories directly to
the battery terminal. Doing so will by-
pass the variable-voltage control sys-
tem and the vehicle battery may not
charge completely.
● Use electrical accessories with the en-
gine running to avoid discharging the
vehicle battery.
Your vehicle is equipped with a variable-voltage
control system. This system measures the
amount of electrical discharge from the battery
and controls voltage generated by the generator.
