Engine Coolant Mixture Ratio=NJMA0006S03The engine cooling system is filled at the factory with a high-quality,
year-round and extended life engine coolant. The high quality
engine coolant contains the specific solutions effective for the anti-
corrosion and the anti-freeze function. Therefore, additional cool-
ing system additives are not necessary.
CAUTION:
When adding or replacing coolant, be sure to use only Genu-
ine NISSAN Anti-freeze Coolant (L2N) or equivalent. Because
L2N is premixed type coolant.
The use of other types of engine coolant may damage your
cooling system.
+When checking the engine coolant mixture ratio by the coolant
hydrometer, use the chart below to correct your hydrometer
reading (specific gravity) according to coolant temperature.

WARNING:
Never remove the radiator cap when the engine is hot. Serious
burns could be caused by high pressure fluid escaping from
the radiator. Wait until the engine and radiator cool down.
