Remove the dipstick, wipe it clean, reinsert it, then remove it again to check the fluid level.
If low, add the appropriate Toyota-approved transmission fluid until it reaches the full mark.

Turn the ignition switch to the "ON" position without starting the engine.
Press the gas pedal fully down three times within five seconds.
Turn the ignition off and then back on to check if the light has been reset.
