OVERDRIVE OFF Lamp This lamp indicates the operating range of the transaxle. This lamp will illuminate when the Overdrive On/Off button is depressed. OVERDRIVE OFF lamp location With the transaxle range selector in the Overdrive j range, the OVERDRIVE OFF lamp will not be illuminated. The transaxle will be allowed to upshift and downshift from 1st through 4th gears. When the Overdrive on/off button is depressed, the OVERDRIVE OFF lamp will illuminate. The transaxle will now only upshift and downshift from 1st through 3rd gears. The vehicle will always return to the overdrive operation mode when the ignition is turned off and back on. If the lamp does not come on when the Overdrive ON/OFF button is depressed or if the lamp flashes when you are driving, have your vehicle serviced at the first opportunity. If this condition persists, damage could occur to the transaxle. Horn To sound the horn, press the center of the steering wheel. Check the horn regularly to make sure it operates properly. 134
