To return the transmission to the normal j Overdrive operation, press the transmission control switch again. The Transmission Control Indicator Light will not be illuminated when Overdrive operation resumes. This switch may be used to select O/D ON or O/D OFF any time the vehicle is being driven. When starting your vehicle, the overdrive system will automatically be in the normal overdrive mode. If the Transmission Control Indicator Light is flashing on and off steadily, a transmission system malfunction was detected. The transmission will operate in a failure management mode and may have harsh engagements, firm shift feel, or abnormal shift schedule. If this condition persists, damage to the transmission could occur. Contact your dealer as soon as possible. When to use 2 (Second) Use 2 (Second) to start-up on slippery roads or to provide additional engine braking on downgrades. This position provides 2 (Second) gear operation only. When to use 1 (Low) Use 1 (Low) to provide maximum engine braking on steep downgrades. Upshifts from 1 (Low) can be made by manually shifting to 2 (Second) or j (Overdrive). Selection of 1 (Low) gear provides only low gear operation from start-up. Selection of 1 (Low) while at higher speeds provides a shift to second gear, and a shift to first gear will occur after the vehicle decelerates to the proper speed. 178
