Engine Oil Recommendation

INFOID:0000000005248711

NISSAN recommends the use of an energy conserving oil in order to improve fuel economy.
Select only engine oils that meet the American Petroleum Institute (API) certification and International Lubri-
cant Standardization and Approval Committee (ILSAC) certification and SAE viscosity standard. These oils
have the API certification mark on the front of the container. Oils which do not have the specified quality label
should not be used as they could cause engine damage.

Anti-Freeze Coolant Mixture Ratio

INFOID:0000000005248712

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 corrosion inhibitors. Therefore, additional cooling
system additives are not necessary.

CAUTION:

When adding or replacing coolant, be sure to use only Genuine
NISSAN Long Life Antifreeze/ Coolant or equivalent with the
proper mixture ratio of 50% anti-freeze and 50% demineralized
water/distilled water.
Other types of coolant solutions may damage your cooling sys-
tem.

WARNING:

Be sure to perform this step when engine is stopped.
• Check that the indicator (C) (notch on fixed side) of drive belt auto-tensioner is within the possible use range

(A).
NOTE:
• Check the drive belt auto-tensioner indication when the engine is cold.
• When new drive belt is installed, the indicator (notch on fixed side) should be within the range (B) in the fig-

ure.

• Visually check entire drive belt for wear, damage or cracks.
• If the indicator (notch on fixed side) is out of the possible use range or belt is damaged, replace drive belt.

WARNING:

• Never change engine coolant when the engine is hot to avoid being scalded.
• Wrap a thick cloth around radiator cap and carefully remove radiator cap. First, turn radiator cap a

quarter of a turn to release built-up pressure. Then turn radiator cap all the way.
