INFINITI QX60-HYBRID 2014 Repair Manual

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.

CHECKING INVERTER COOLANT
LEVEL
Check the coolant levelin the reservoir when
the engine and inverter are cold. The coolant
level should be between the MIN level
B, add
coolant to the MAX level
A.
If the inverter cooling system frequently
requires coolant, have it checked by a
INFINITI retailer.
CHANGING INVERTER COOLANT
Major cooling system repairs should be done by a
INFINITI retailer. The service procedure can be
found in the INFINITI Service Manual.
Improper servicing can result in inverter
overheating.
WARNING
● To avoid the danger of being scalded,
never change the coolant when the in-
verter is hot.
● Never remove the cap when the inverter
is hot. Serious burns could be caused by
high pressure fluid escaping from the
inverter coolant reservoir.
● Avoid direct skin contact with used
coolant. If skin contact is made, wash
thoroughly with soap or hand cleaner as
soon as possible.
● Keep coolant out of the reach of chil-
dren and pets.
Engine coolant must be disposed of properly.
Check your local regulations.
CHECKING ENGINE OIL LEVEL
1. Park the vehicle on a level surface and apply the parking brake.
2. Start the engine and let it idle until it reaches operating temperature.
3. Turn off the engine. Wait more than
10 minutes for the oil to drain back into
the oil pan.

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.
