Overdrive Off Indicator (If equipped) This light tells you that the Transmission Control Switch (TCS) on the gearshift lever has been pushed. When the light is on, the transmission does not shift into overdrive. Depressing the button on the shifter once more returns the vehicle to overdrive mode. The transmission will be in the overdrive mode when the vehicle is started even if the O/D OFF mode was selected when the vehicle was last shut off. NOTE: If the light does not come on when the TCS is depressed 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 transmission. Overdrive off light (if equipped) Charging System Light This light, shown as a battery symbol on your cluster, indicates that your battery is not being charged and that you need to have the electrical system checked.
