check engine INFINITI QX60-HYBRID 2015 Repair Manual

WARNING
●To avoid the danger of being scalded,
never change the coolant when the en-
gine is hot.
● Never remove the radiator or engine
coolant reservoir cap when the engine
is hot. Serious burns could be caused by
high pressure fluid escaping from the
radiator.
● 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. 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 antifreeze and
coolant protection. The antifreeze 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.
For additional information, refer to the
INFINITI Service and Maintenance
Guide.
