maged.
(2) If operating mainly in dusty conditions, more frequent maintenance may be required.
(3) Maintenance-free item. For service procedures, go to the FL section.
(4) After 60,000 miles (96,000 km) or 48 months, replace every 30,000 miles (48,000 km) or 24 months.

6. Install the lower glove box in the instrument panel and secure it
with the two hinge pins.
Checking Exhaust SystemINFOID:0000000001606180
Check exhaust pipes, muffler and mounting for improper attachment,
leaks, cracks, damage, loose connec tions, chafing or deterioration.
Checking Automatic Transmission Fluid (ATF)INFOID:0000000001606181
1. Remove the ATF level gauge bolt.
2. Before driving, the ATF level can be checked at ATF 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 shift selector through each gear position. Move the shift selector into the “P” position.
c. Check the ATF level with the engine idling.
d. Remove the ATF level gauge and wipe it clean with a lint-free paper.
CAUTION:
When wiping the ATF 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 ATF 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 ATF level. If the ATF level is at low side of range, add ATF to the transmission
through the charging pipe.
CAUTION:
Do not overfill the tr ansmission with ATF.
g. Install the ATF level gauge and the ATF level gauge bolt.
3. Warm up the engine.
4. Check for any ATF leaks.

5. Drive the vehicle to increase the ATF temperature to 80° C (176 ° F).
6. Allow the ATF temperature to fall to approximately 65 °C (149° F). Use the CONSULT-III to monitor the ATF
temperature as follows:
NOTE:
ATF level will be greatly affected by temperature as shown. Therefore monitor the ATF temperature data
using the CONSULT-III.
a. Connect CONSULT-III to data link connector.
b. Select “MAIN SIGNALS” in “DATA MONI TOR” mode for “A/T” with CONSULT-III.
c. Read out the value of “ATF TEMP 1”.
7. Re-check the ATF level at ATF temperatures of approximately 65°C (149° F) using the “HOT” range on the ATF level gauge as
shown.
CAUTION:
• When wiping the ATF from the ATF level gauge, always use lint-free paper, not a cloth.
• To check the ATF level, insert the ATF level gauge until the cap contacts the top of the ch arging pipe, with the gauge
reversed from the normal inserted position as shown.
8. Check the ATF condition. • If the ATF is very dark or has some burned smell, there may be an internal problem with the transmis-
sion. Refer to TM-178, "
Checking the A/T Fluid (ATF)". Flush the transmission cooling system after
repairing the transmission.
• If the ATF contains frictional material (clutches, bands , etc.), replace the radiator and flush the transmis-
sion cooler lines using cleaning solvent and compressed air after repairing the transmission.
9. Install the ATF level gauge in the ATF charging pipe and install the level gauge bolt.

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 aux iliary 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% of the specified capacity.
CAUTION:
• Use only the specified ATF. Do not mix with other fluids.
• Using an ATF other than the speci fied ATF will cause deterioration in driveability and automatic
transmission durability, and may damage the au tomatic 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 TM-178, "
Checking the A/T Fluid (ATF)". If the ATF is still
dirty, repeat steps 2 through 5.
