OFF

•

Transmission: Neutral <M/T>, "P" range <A/T>

•

Power steering: Static state

3. Select SPECIAL FUNCTION from the function

menu.

4. Select SMALL INJECTION QUANTITY

LEARNING from the SPECIAL FUNCTION menu
to execute learning.

CAUTION

•

If the vehicle conditions go out of the learning
conditions during idling, learning is inter-
rupted.

•

To reexecute learning, the ignition switch
must once be turned off.

5. Continue idling for about 3 minutes before
