Mine is a 2010 model and the mode is indicated on the dash
its on the counsel near the shift lever
On a 1998 Ford Taurus ; On the column shift the overdrive button is on the end of the gear shift lever On the console shift the overdrive button is on the drivers side of the gear selector lever below the button you have to press to shift out of PARK
It is used to force a downshift.
its on the shift lever of my dx where your thumb hits the lever
check the brake pedal switch
You can open it with a key, remote, or knob by shift lever
This unfortunatly indicates a transmission problem.
Press the shift lever detent button then lift up sharply
isn,t that the over drive button
I assume that is the button that allows you to turn off or turn on the overdrive for the transmission ( my Ford Explorer also has a button on the end of the gear shift lever for that purpose )
bad fuse or bad switch
The shift lock button is used when the battery has discharged or the ignition isn't turned on, once the button is pressed it allows the gear lever to be moved from P (parking) to N (neutral).
