ENGINE MAINTENANCE (VK56DE)
• Before starting the engine make sure the vehicle is parked on a flat
and level surface, then check the oil level. If the engine is already
running, turn it off and allow 10 minutes before checking.
• Pull out oil level gauge and wipe clean.
• Insert oil level gauge.
• Check that the oil level is within the low (L) and high (H) range as
indicated on the dipstick.
• If the engine oil level is out of range, add oil as necessary. Refer to
MA-18, "FOR USA AND CANADA : Fluids and Lubricants"
.
CAUTION:
Do not overfill the engine with oil.
ENGINE OIL : Changing Engine Oil
INFOID:0000000007347378
WARNING:
• Be careful not to burn yourself, as the engine and engine oil may be 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. Refer to
CAUTION:
Do not overfill the engine with oil.

A/T FLUID
A/T FLUID : Checking the A/T Fluid (ATF)
INFOID:0000000007347385
CAUTION:
If using the vehicle for towing, the A/T fluid must be replaced as specified. Refer to
AND CANADA : Introduction to Periodic Maintenance"
(United States and Canada) or
MEXICO : Periodic Maintenance Schedule"
(Mexico)
1. Before driving, the A/T fluid level can be checked at A/T fluid
temperatures of 30
°
to 50
°
C (86
°
to 122
°
F) using the “COLD”
range on the A/T fluid level gauge as follows:
a. Park the vehicle on a level surface and set the parking brake.
b. Start the engine and move the selector lever through each gear
position. Shift the selector lever into the “P” position.
c. Check the A/T fluid level with the engine idling.
d. Remove the A/T fluid level gauge and wipe it clean with a lint-
free paper.
CAUTION:
When wiping the A/T fluid from the A/T fluid level gauge,
always use a lint-free paper, not a cloth.
e. Re-insert the A/T fluid level gauge into the A/T fluid charging
pipe until the cap contacts the top of the A/T fluid charging pipe
as shown.
CAUTION:
To check A/T fluid level, insert the A/T fluid level gauge until
the cap contacts the top of the A/T fluid charging pipe, with
the gauge reversed from the normal inserted position.
f.
Remove the A/T fluid level gauge and note the A/T fluid level. If
the A/T fluid level is at low side of range, add A/T fluid to the
transmission through the A/T fluid charging pipe.
CAUTION:
Do not overfill the transmission with A/T fluid.
g. Install the A/T fluid level gauge and the A/T fluid level gauge bolt.
2. Warm up the engine and transmission.
3. Check for any A/T fluid leaks.
4. Drive the vehicle to increase the A/T fluid temperature to 80
°
C (176
°
F).

5. Allow the A/T fluid temperature to fall to approximately 65
°
C (149
°
F). Use the CONSULT to monitor the A/
T fluid temperature as follows:
NOTE:
The A/T fluid level will be significantly affected by the A/T fluid temperature as shown. Therefore monitor
the A/T fluid temperature data using the CONSULT.
a. Connect CONSULT to data link connector.
b. Select “MAIN SIGNALS” in “DATA MONITOR” mode for “A/T” with CONSULT.
c.
Read out the value of “ATF TEMP 1”.
6. Re-check the A/T fluid level at A/T fluid temperatures of approxi-
mately 65
°
C (149
°
F) using the “HOT” range on the A/T fluid
level gauge as shown. The HOT range is between 50
°
- 80
°
C
(122
°
- 176
°
F).
CAUTION:
• When wiping the A/T fluid from the A/T fluid level gauge,
always use lint-free paper, not a cloth.
• To check the A/T fluid level, insert the A/T fluid level
gauge until the cap contacts the top of the A/T fluid charg-
ing pipe, with the gauge reversed from the normal
inserted position as shown.
7. Check the A/T fluid condition.
• If the A/T fluid is very dark or has some burned smell, there
may be an internal problem with the transmission. Refer to
. Flush the transmission cooling system after repairing
the transmission.
• If the A/T fluid contains frictional material (clutches, bands,
etc.), replace the radiator and flush the transmission cooler
lines using cleaning solvent and compressed air after repairing
the transmission.
8. Install the A/T fluid level gauge in the A/T fluid charging pipe.
9. Tighten the A/T fluid level gauge bolt to specification.

A/T FLUID : Changing the A/T Fluid (ATF)
INFOID:0000000007347386
CAUTION:
If using the vehicle for towing, the A/T fluid must be replaced as specified. Refer to
AND CANADA : Introduction to Periodic Maintenance"
(United States and Canada) or
MEXICO : Periodic Maintenance Schedule"
(Mexico).
1. Drive the vehicle to warm up the A/T fluid to approximately 80
°
C (176
°
F).
2. Stop the engine.
3. Remove the A/T fluid level gauge.
4. Drain the A/T fluid from the drain plug hole, then install the drain
plug with a new gasket. Refill the transmission with new A/T
fluid. Always refill with the same volume as the drained A/T fluid.
Use the A/T fluid level gauge to check the A/T fluid level as
shown. Add A/T fluid as necessary.
• To flush out the old A/T fluid from the transmission oil coolers, pour new A/T fluid into the A/T fluid charg-
ing pipe with the engine idling and at the same time drain the old A/T fluid from the auxiliary transmis-
sion oil cooler hose return line.
• When the color of the A/T fluid coming out of the auxiliary transmission oil cooler hose return line is
about the same as the color of the new A/T fluid, flushing out the old A/T fluid is complete. The amount
of new A/T fluid used for flushing should be 30% to 50% increase of the specified capacity.
CAUTION:
• If Genuine NISSAN Matic S ATF is not available, Genuine NISSAN Matic J ATF may also be used.
Using automatic transmission fluid other than Genuine NISSAN Matic S or Matic J will cause
deterioration in driveability. and may damage automatic transmission, which is not covered by
the NISSAN new vehicle limited warranty.
• When filling the transmission with A/T fluid, do not spill the A/T fluid on any heat generating
parts such as the exhaust manifold.
• Do not reuse the drain plug gasket.
5. Install the A/T fluid level gauge and tighten the A/T fluid level gauge bolt to specification.
6. Drive the vehicle to warm up the A/T fluid to approximately 80
°
C (176
°
F).
7. Check the fluid level and condition. If the A/T fluid is still dirty,
repeat steps 2 through 6.
