7Speed Mode Control

The 6-position CVT+7Speed Mode is provided with the 7Speed Mode in the D and S positions. The 7Speed Mode has two modes; the 7-speed automatic mode and 7-speed manual shifting mode. The transmission switches to the 7-speed automatic mode with pushing the 7SPEED MODE main switch. In the 7-speed automatic mode, the transmission can be shifted up and down automatically in 7-stage speeds of pulley ratios, and the steering shift switches are ready to be activated switching to 7-speed manual shifting mode. When the steering shift switch is activated, the 7-speed automatic mode will be cancelled and 7-speed manual shifting mode comes into operation. In the 7-speed manual shifting mode, the driver can shift up and down manually in 7-stage speeds with using the steering shifting switches; much like a manual transmission.
The 7Speed Mode is cancelled by pushing the 7SPEED MODE main switch or when moving the shift lever to any position other than D and S.

The 7SPEED MODE main switch (A), steering shift + (plus) switch (B), and steering shift - (minus) switch (C) are installed on the steering wheel. The driver can select the modes and speed stages with pressing the switches without taking either hand off the steering wheel.

 

SAA5ES2E15117700000CAAD03ABC

The shift indicator (A) and M indicator (B) are in the gauge assembly (C) next to the A/T gear position indicator (D).

 

SAA5ES2E15117700000CAAD04CDAB

In the 7-speed automatic mode, the shift indicator displays the number of currently-selected speed stage. The M indicator does not come on in this mode.
In the 7-speed manual shifting mode, the M indicator comes on, and the shift indicator displays the number of the selected speed stage.
