DESCRIPTION

When 2nd start mode is selected with the pattern select (2ND) switch, the ECM controls the solenoid valves and the transmission starts from 2nd gear.

The 2nd mode is the system that operates the throttle motor to control engine output to reduce skidding of the driving wheels, and guarantee takeoff acceleration, driving straightness and turning stability.

When the shift lever is in D, the transmission automatically shifts up through 2nd to 5th as usual.

Tip:

  • The pattern select (2ND) switch is a momentary-type switch.

  • In order to cancel 2nd mode, push the pattern select (2ND) switch again or turn the ignition switch off.
