Accelerator downshift - in D position - For passing or hill climbing, depress the accelerator pedal to the floor. This shifts the transmission down into a lower gear, depending on the vehicle speed. OFF: For driving up and down long slopes where engine braking is necessary push the Overdrive switch once. The O/D OFF indicator light in the instrument panel comes on at this time. Fail-safe When the fail-safe operation occurs, please note that the 4-speed automatic transmission will be locked in third gear. For the 5-speed automatic transmission, the transmission will be locked in any of the gears according to the condition. If the vehicle is driven under extreme conditions, such as excessive wheel spinning and subsequent hard braking, the fail-safe system may be activated. This will occur even if all electrical circuits are functioning properly. In this case, turn the ignition key OFF and wait for 3 seconds. Then turn the key back to the ON position.
