Why is the shift light on all the time in the Teana?

[IsabelaLynn]

Teana shift light stays on because the gear is not in the parking position. Car Shift Key: Shift means gear shifting. At 15 km/h, it prompts to shift to 2nd gear; at 30 km/h, to 3rd gear; at 45 km/h, to 4th gear; and at 59 km/h, to 5th gear. If you don't shift up, it can cause the engine to run at excessively high RPM. Function of Car Gear Shifting: It allows the car to run at very low and stable RPM, which is difficult to achieve solely by the minimum stable RPM of the internal combustion engine. The reverse gear in the transmission enables the car to move backward, while the neutral gear allows the engine to be separated from the drivetrain for extended periods during engine start-up, parking, or coasting. Prolonged use of low gears is generally less fuel-efficient than high gears, so it's advisable to shift up promptly after starting.
