The engine cooling system is filled at the factory
with Genuine NISSAN Long Life Antifreeze/
Coolant to provide year-round anti-freeze and
coolant protection. The anti-freeze solution con-
tains rust and corrosion inhibitors. Additional en-
gine cooling system additives are not necessary.
WARNING
● Never remove the radiator or coolant
reservoir cap when the engine is hot.
Wait until the engine and radiator cool
down. Serious burns could be caused
by high pressure fluid escaping from
the radiator. See precautions in “If your
vehicle overheats” found in the “In case
of emergency” section of this manual.
● The radiator is equipped with a pres-
sure type radiator cap. To prevent en-
gine damage, use only a genuine
NISSAN radiator cap.
CAUTION
When adding or replacing coolant, be sure
to use only a Genuine NISSAN Long Life
Antifreeze/Coolant (green) or equivalent
with the proper mixture ratio of 50% anti-
freeze and 50% demineralized or distilled
water. The use of other types of coolant
solutions or coolant colors, such as or-
ange, may damage the engine cooling
system.
