The engine cooling system is filled at the
factory with a high-quality, year-round, anti-
freeze coolant solution. The anti-freeze so-
lution contains rust and corrosion inhibitors,
therefore additional engine cooling system
additives are not necessary.
CAUTION
When adding or replacing coolant, be
sure to use only a Genuine Nissan
anti-freeze coolant (green) or equiva-
lent 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
the 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, add coolant up to the MAX
level. If the reservoir tank is empty, check
the coolant level in the radiatorwhen the
engine is cold.If there is insufficient cool-
ant in the radiator, fill the radiator with
coolant up to the filler opening and also add
it to the reservoir tank up to the MAX level.

and pets.
CHECKING ENGINE OIL LEVEL
1. Park the vehicle on a level surface and
apply the parking brake.
2. Start the engine and let it idle until it
reaches operating temperature.
3. Turn the engine off.Wait a few minutes
for the oil to drain back into the oil
pan.
4. Remove the dipstick and wipe it clean.
Reinsert it all the way.5. Remove the dipstick again and check the
oil level. It should be between the H
(High) and L (Low) marks. If the oil level
is below the L (Low) mark, remove the oil
filler cap and pour recommended oil
through the opening.Do not overfill.
6. Recheck the oil level with the dipstick.
It is normal to add some oil between oil
maintenance intervals or during the
break-in period, depending on the sever-
ity of operating conditions.

TEMPERATURE CONDITIONS
FOR CHECKING
cCheck the fluid level using the HOT
range on the dipstick after the following
conditions have been met:
Ð The engine is warmed up to operating
temperature.
Ð The vehicle is driven at least 15 minutes.
Ð The automatic transmission fluid is
warmed to between 150ÉF and 170ÉF
(66ÉC and 77ÉC).
cThe fluid can be checked at fluid tem-
peratures of 70ÉF to 95ÉF (21ÉC to 35ÉC)
using the COLD range on the dipstick
after the engine is warmed up and before
driving. However, the fluid should be
re-checked using the HOT range.
