A: PROCEDURE
WARNING:
Observe the traffic law during driving on roads.
1) Shift the select lever to “D” range, and then drive
the vehicle with changing the gear from 1st to 5th.
2) When driving the vehicle at 5th speed of “D”
range, set the gear to manual mode and drive the
vehicle by downshifting using “–” of the select lever
from 5th → 4th, 4th → 3rd, 3rd → 2nd, and 2nd →
1st.
