*1: For further details, refer to MA-10, "SAE Viscosity Number" .
*2: Using automatic transmission fluid other than Genuine NISSAN Matic J ATF will cause deterioration in driveability and automatic
transmission durability, and may damage the automatic transmission, which is not covered by the INFINITI new vehicle limited warranty.
*3: For Canada, NISSAN Automatic Transmission Fluid (ATF), DEXRON
TM III or MERCONTM or equivalent ATF may also be used.
*4: Available in mainland U.S.A. through your INFINITI dealer.

*6: For hot climates, viscosity SAE 90 is suitable for ambient temperatures above 0° C (32° F).
*7: DEXRON
TM III, MERCONTM or equivalent may also be used. Outside the continental United States and Alaska contact a INFINITI
dealership for more information regarding suitable fluids, including recommended brand(s) of DEXRONTM III or MERCONTM Automatic
Transmission Fluid.
*8: For improved vehicle performance, INFINITI recommends the use of unleaded premium gasoline with an octane rating of at least 91
AKI (RON 96). For further details, refer to GI-4, "
Precaution for Fuel (Unleaded Premium Gasoline Required)" .

Changing Engine OilINFOID:0000000003533871
WARNING:
• Be careful not to burn yourself, as the engine and engine oil are hot.
• Prolonged and repeated contact with used engine oil may cause skin cancer; try to avoid direct skin
contact with used oil. If skin contact is made, wash thoroughly with soap or hand cleaner as soon as
possible.
1. Warm up the engine, and check for any oil leaks.
2. Stop the engine and wait for at least 10 minutes.
3. Remove the oil drain plug and oil filler cap to drain the old oil.
4. Install a new washer on the oil drain plug, then install the oil drain plug in the oil pan.
CAUTION:
Clean the drain plug and install with a new washer.
5. Refill the engine with new specified engine oil.
CAUTION:
The refill capacity depends on the oil temperature and drain time. Use the “Refill oil capacity” val-
ues as a reference and check the oil level using the dipstick when filling the engine with oil.
6. Warm up the engine and check the area around the drain plug and oil filter for any oil leaks.
7. Stop the engine and wait for more than 10 minutes.
8. Check the oil level using the dipstick as shown. Add oil as nec-
essary and install the oil filler cap.
CAUTION:
Do not overfill the engine with oil.

Changing Automatic Transmission Fluid (ATF)INFOID:0000000003533878
1. Drive the vehicle to warm up the ATF to 80° C (176° F).
2. Stop the engine.
3. Remove the ATF level gauge bolt.
4. Drain the ATF from the drain plug hole and then install the drain
plug with a new gasket. Refill the transmission with new ATF.
Always refill with the same volume as the drained ATF. Use the
ATF level gauge to check the ATF level as shown. Add ATF as
necessary.
• To flush out the old ATF from the coolers, pour new ATF into the charging pipe with the engine idling and
at the same time drain the old ATF from the auxiliary transmission oil cooler hose return line.
• When the color of the ATF coming out of the auxiliary transmission oil cooler hose return line is about
the same as the color of the new ATF, flushing out the old ATF is complete. The amount of new trans-
mission ATF used for flushing should be 30% to 50% increase of the specified capacity.
CAUTION:
• Use only the specified ATF. Do not mix with other fluids.
• Using an ATF other than the specified ATF will cause deterioration in driveability and automatic
transmission durability, and may damage the automatic transmission, which is not covered by
the warranty.
• When filling the transmission with ATF, do not spill the ATF on any heat generating parts such as
the exhaust manifold.
• Do not reuse the drain plug gasket.
5. Install the ATF level gauge in the ATF charging pipe and tighten the level gauge bolt to specification.
6. Drive the vehicle to warm up the ATF to 80° C (176° F).
7. Check the ATF level and condition. Refer to AT-13, "
Checking Automatic Transmission Fluid (ATF)". If the
ATF is still dirty, repeat steps 2 through 5.
