ON-VEHICLE SERVICE
Automatic Transmission Fluid (ATF) Replacement
Draining
1. Turn off all the electrical devices and ignition switch.
2. Raise the vehicle with a lifter.
3. Place a collection vessel under the oil outlet of transmission.
4. Unscrew the drain bolt to drain ATF. After draining,
replace the drain bolt gasket and tighten the bolt.
(Tightening torque: 29 - 34 N·m)
Filling
1. Add new ATF along the oil dipstick pipe (filling quantity is
equal to that of the drained).
2. Start engine to make it run for 1 - 2 min.
3. Step on the brake pedal and move the shift lever at each
gear and place it to "N" or "P" position.
CAUTION
Replace gasket after removing drain bolt every time.
If automatic transmission fluid level is too low, add ATF until it reaches "HOT" position.

Inspection
1. After the vehicle runs for 5 min, the temperature will reach the normal working conditions (ATF temperature
60 - 80°C, and the engine coolant temperature 80 - 100°C).
2. Park the vehicle on a flat ground and pull the parking brake lever.
3. Start engine to make it run at idle speed, and then fully depress the brake pedal and move the shift lever
for five times at each gear. Finally, place the lever at "P" or "N" position.
4. Pull out the automatic transmission fluid dipstick and
clean it with a piece of non-wool paper; then insert the
dipstick into the filling pipe as much as possible and then
take out to observe whether it reaches the "HOT"
position.
