Driving When to use j Overdrive Overdrive is the normal driving position. When the gearshift lever is placed in j Overdrive, and the Overdrive Off button has not been pressed, the vehicle will automatically upshift to second, third and fourth gears. The transaxle will shift into the correct gear when the right speed is reached. When to use D (Drive) - with the Overdrive Off button activated You will notice that there is only one drive position on your gearshift indicator (instead of Drive and Overdrive). However, you will find a button and an indicator light located on the gearshift lever. Push in the button on the end of the lever and the OVERDRIVE OFF light on the end of the gearshift lever will illuminate. With the OVERDRIVE OFF light illuminated, the transaxle will operate in first, second and third gears and will not shift into fourth gear. Operating in Drive (OVERDRIVE OFF light illuminated) provides more engine braking than Overdrive for descending hills or city driving. Overdrive button location To return the transaxle to the normal Overdrive operation, press the OVERDRIVE ON/OFF button again. Use this button to select Overdrive or Overdrive Off whenever you drive your vehicle. The transaxle will be in the "overdrive on" mode when the vehicle is started even if the O/D OFF mode was selected when the vehicle was last shut off. 231
