The overdrive function allows automatic upshifts and downshifts through
all available gears.

Deactivating overdrive

If your vehicle is equipped with a
floor-shift transmission, overdrive
can be deactivated by pressing the
Transmission Control Switch (TCS)
on the gearshift handle.
The Transmission Control Indicator
Light (TCIL) will illuminate on the

To return to normal overdrive mode, press the Transmission Control
Switch again. The TCIL will no longer be illuminated.
When you shut off and re-start your vehicle, the transmission will
automatically return to normal (Overdrive) mode.
