The engine cooling system is filled at the factory
with a high-quality, year-round, anti-freeze cool-
ant solution. The anti-freeze solution contains
rust and corrosion inhibitors, therefore additional
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 escap-
ing from the radiator. See precau-
tions in “If your vehicle overheats”
found in the “6. In case of emer-
gency” section of this manual.
The radiator is equipped with a pres-
sure type radiator cap. To prevent
engine 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% demineral-
ized water/distilled water. The use of
other types of coolant solutions may
damage your engine cooling system.
CHECKING ENGINE COOLANT
LEVEL
Check the coolant level in the reservoir tank
when the engine is cold. If the coolant level is
below MIN
1
, add coolant up to the MAX
2
level. If the reservoir tank is empty, check the
coolant level in the radiator when the engine is
cold. If there is insufficient coolant in the radia-
tor, fill the radiator with coolant up to the filler
opening and also add it to the reservoir tank up
to the MAX
2
level.
Tighten the cap securely after adding engine
coolant.
