Overdrive OFF indicator light To return the transaxle to normal operation (1st through 4th gears) press the O/D OFF button again. The O/D OFF button may be used to cancel Overdrive any time the vehicle is being driven. Each time your vehicle is started, the Overdrive system will automatically be in the normal "overdrive on" mode and the light will not be illuminated. If the light does not illuminate when the O/D OFF button is pressed, or if the light flashes when you are driving, have your vehicle serviced at the first opportunity. If this condition persists, damage could occur to the transaxle. When to use Drive (D with Overdrive OFF) In Drive (Overdrive OFF), your vehicle automatically upshifts or downshifts from 1st through 4th gears as the vehicle speeds up or slows down. It also downshifts when you need extra acceleration to pass or when driving up a hill. Selecting Drive (Overdrive OFF) will eliminate the transaxle's tendency to "hunt" between third and fourth gears while driving over hilly terrain. It also gives your vehicle more engine braking to slow your vehicle than Overdrive does. 144
