6. Install the lower glove box in the instrument panel and secure it
with the two hinge pins.
Checking Exhaust SystemELS001BZ
Check exhaust pipes, muffler and mounting for improper attachment,
leaks, cracks, damage, loose connections, chafing or deterioration.
Checking A/T FluidELS001C0
1. Warm up the engine.
2. Check for any fluid leaks.
3. Remove the tightening bolt for the ATF level gauge.
4. Before driving, the fluid level can be checked at fluid tempera-
tures of 30° to 50°C (86° to 122°F) using the “COLD” range on
the ATF 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 fluid level with the engine idling.
d. Remove the ATF level gauge and wipe it clean with a lint-free
paper.
CAUTION:
When wiping the fluid from the ATF level gauge, always use
a lint-free paper, not a cloth.
e. Re-insert the ATF level gauge into the charging pipe until the
cap contacts the top of the charging pipe as shown.
CAUTION:
To check fluid level, insert the ATF level gauge until the cap
contacts the top of the charging pipe, with the gauge
reversed from the normal inserted position.
f. Remove the ATF level gauge and note the fluid level. If the fluid
level is at low side of range, add fluid to the transmission
through the charging pipe.
CAUTION:
Do not overfill the transmission with fluid.
5. Drive vehicle for approximately 5 minutes in urban areas.

6. Drive the vehicle for at least five minutes or until the fluid temperature reaches approximately 65°C
(149°F).Use the CONSULT-II to monitor the fluid temperature as follows:
NOTE:
Fluid level will be greatly affected by temperature as shown. Therefore monitor the fluid temperature data
using the CONSULT-II.
a. Connect CONSULT-II to data link connector.
b. Select “MAIN SIGNALS” in “DATA MONITOR” mode for “A/T” with CONSULT-II.
c. Read out the value of “ATF TEMP 1”.
7. Re-check the fluid level at fluid temperatures of approximately
65°C (149°F) using the “HOT” range on the A/T fluid level gauge
as shown.
CAUTION:

When wiping the fluid from the ATF level gauge, always
use lint-free paper, not a cloth.

To check the fluid level, insert the ATF level gauge until
the cap contacts the top of the charging pipe, with the
gauge reversed from the normal inserted position as
shown.
8. Check the fluid condition.

If the fluid is very dark or smells burned, there may be an
internal problem with the transmission. Refer to AT - 4 1 ,
"TROUBLE DIAGNOSIS" . Flush the transmission cooling
system after repairing the transmission.

If the ATF 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.
9. Install the ATF level gauge in the fluid charging pipe and install the level gauge bolt. Tighten the level
gauge bolt to specification.

Changing A/T FluidELS001C1
1. Run the engine to warm up the ATF.
2. Stop the engine.
3. Remove the bolt for the ATF level gauge.
4. Drain the ATF from the drain plug hole and refill the transmission
with new ATF. Always refill same volume with drained fluid and
use the dipstick to check the fluid level as shown. Add fluid as
necessary.

To flush out the old fluid from the coolers, pour new fluid into the charging pipe with the engine idling
and at the same time drain the old fluid from the auxiliary transmission oil cooler hose return line.

When the color of the fluid coming out of the auxiliary transmission oil cooler hose return line is about
the same as the color of the new fluid, flushing out the old fluid is complete. The amount of new trans-
mission fluid used for flushing should be 30% to 50% of the specified capacity.
CAUTION:

Use only Genuine NISSAN ATF Matic Fluid J. Do not mix with other fluid.

Using automatic transmission fluid other than Genuine NISSAN ATF Matic Fluid J will cause
deterioration in driveability and automatic transmission durability, and may damage the auto-
matic transmission, which is not covered by the warranty.

When filling the transmission with fluid, do not spill the ATF on any heat generating parts such
as the exhaust manifold.
5. Check the fluid level and condition. Refer to MA-22, "
Checking A/T Fluid" . If the fluid is still dirty, repeat
steps 2 through 5.
6. Install the ATF level gauge in the fluid charging pipe and install the level gauge bolt. Tighten the level
gauge bolt to specification.
Changing Transfer FluidELS001H0
DRAINING
1. Stop the engine.
2. Remove the drain plug and gasket to drain the transfer fluid as
shown.
3. Install the new gasket on the drain plug and install the drain plug
in the transfer. Tighten the drain plug to specification.
CAUTION:
Do not reuse the gasket.

How to Handle BatteryEKS00B78
CAUTION:

If it becomes necessary to start the engine with a booster battery and jumper cables, use a 12-volt
booster battery.

After connecting battery cables, ensure that they are tightly clamped to battery terminals for good
contact.

Never add distilled water through the hole used to check specific gravity.
METHODS OF PREVENTING OVER-DISCHARGE
The following precautions must be taken to prevent over-discharging
a battery.

The battery surface (particularly its top) should always be kept
clean and dry.

The terminal connections should be clean and tight.

At every routine maintenance, check the electrolyte level.
This also applies to batteries designated as “low maintenance”
and “maintenance-free”.

When the vehicle is not going to be used over a long period of
time, disconnect the negative battery terminal.

Check the charge condition of the battery.
Periodically check the specific gravity of the electrolyte. Keep a
close check on charge condition to prevent over-discharge.
CHECKING ELECTROLYTE LEVEL
WAR NIN G:
Do not allow battery fluid to come in contact with skin, eyes, fabrics, or painted surfaces. After touch-
ing a battery, do not touch or rub your eyes until you have thoroughly washed your hands. If acid con-
tacts eyes, skin or clothing, immediately flush with water for 15 minutes and seek medical attention.

Remove the cell plug using a suitable tool.

Add distilled water up to the MAX level.
Sulphation
A battery will be completely discharged if it is left unattended
for a long time and the specific gravity will become less than
1.100. This may result in sulphation on the cell plates.
To determine if a battery has been “sulphated”, note its voltage
and current when charging it. As shown in the figure, less cur-
rent and higher voltage are observed in the initial stage of
charging sulphated batteries.
A sulphated battery may sometimes be brought back into ser-
vice by means of a long, slow charge, 12 hours or more, fol-
lowed by a battery capacity test.
SPECIFIC GRAVITY CHECK
1. Read hydrometer and thermometer indications at eye level.
2. Use the following chart to correct your hydrometer reading
according to electrolyte temperature.
