Changing the In-cabin Microfilter

ELS001OO

Open the lower glove box and press in on the sides so that it will
open completely allowing it to hang by the cord.

Remove the screw and remove the in-cabin microfilter cover.

Remove the in-cabin microfilters from the front heater and cool-
ing unit housing.

Insert the first new in-cabin microfilter into the front heater and
cooling unit housing and slide it over to the right. Insert the sec-
ond new in-cabin microfilter into the front heater and cooling unit
housing.

NOTE:
The in-cabin microfilters are marked with air flow arrows. The
end of the microfilter with the arrow should face the rear of the
vehicle. The arrows should point downward.

Install the in-cabin microfilter cover.

Close the lower glove box completely.

Checking the Exhaust System

ELS001OP

Check exhaust pipes, muffler and mounting for improper attachment,
leaks, cracks, damage, loose connections, chafing or deterioration.

Checking the A/T Fluid (ATF)

ECS00FSK

CAUTION:

If using the vehicle for towing, the A/T fluid must be replaced as specified. Refer to

MA-7, "PERIODIC

MAINTENANCE"

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:

Park the vehicle on a level surface and set the parking brake.

Start the engine and move the selector lever through each gear
position. Shift the selector lever into the “P” position.

Check the A/T fluid level with the engine idling.

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.

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.

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.

Install the A/T fluid level gauge and the A/T fluid level gauge bolt.

Warm up the engine and transmission.

Check for any A/T fluid leaks.

Drive the vehicle to increase the A/T fluid temperature to 80

C (176

F).

Allow the A/T fluid temperature to fall to approximately 65

C (149

F). Use the CONSULT-II 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-II.

Connect CONSULT-II to data link connector.

Select “MAIN SIGNALS” in “DATA MONITOR” mode for “A/T” with CONSULT-II.

Read out the value of “ATF TEMP 1”.

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

(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
charging pipe, with the gauge reversed from the normal
inserted position as shown.

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

AT-175, "TROUBLE DIAGNOSIS FOR SYMPTOMS"

. Flush

the transmission cooling system after repairing the transmis-
sion.

●

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.

Install the A/T fluid level gauge in the A/T fluid charging pipe.

Tighten the A/T fluid level gauge bolt to specification.

Changing the A/T Fluid (ATF)

ECS00FSL

CAUTION:

If using the vehicle for towing, the A/T fluid must be replaced as specified. Refer to

MA-7, "PERIODIC

MAINTENANCE"

Drive the vehicle to warm up the A/T fluid to approximately 80

C (176

F).

Stop the engine.

Remove the A/T fluid level gauge.

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
charging pipe with the engine idling and at the same time drain the old A/T fluid from the auxiliary trans-
mission 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% of the specified capacity.

CAUTION:

●

Use only Genuine NISSAN Matic J ATF and do not mix with other fluids.

●

Using A/T 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 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.

Install the A/T fluid level gauge and tighten the A/T fluid level gauge bolt to specification.

Drive the vehicle to warm up the A/T fluid to approximately 80

C (176

F).

Check the fluid level and condition. If the A/T fluid is still dirty,
repeat steps 2 through 6.
