The engine cooling system is filled at the
factory with a high-quality, year-round,
anti-freeze coolant solution. The anti-
freeze solution contains rust and corro-
sion
inhibitors,
therefore
additional
cooling system additives are not neces-
sary.
WARNING
O
Never remove the radiator cap when the
engine is hot. Wait until the engine and
radiator cool down. Serious burns could
be caused by high pressure fluid es-
caping from the radiator. See “If your ve-
hicle overheats” in the “6. In case of
emergency” section.
O
The radiator is equipped with a pressure
type radiator cap. To prevent engine
damage, use only a genuine NISSAN ra-
diator cap.

CAUTION
When adding or replacing coolant, be sure to
use only a Genuine NISSAN Long Life Anti-
freeze 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 orange, 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 cool-
ant level is below MIN
q
2
, add coolant up
to the MAX
q
1
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 radiator, fill the
radiator with coolant up to the filler open-
ing and also add it to the reservoir tank
up to the MAX level
