Toyata Hilux 2KD-FTV2494 Kun 2.5 L

How can I erase the lux after changing the belt to this car and the di -filter light

To restart the T -Belt it is the following:
- Turn the ignition key to on
- press the ODO/TRIP button and leave it in odo, then return the ignition
key to off
- keep pressing the ODO/TRIP 5 second button
- The number 15 appears on the digital odometer

.
And for the filter light it should be sufficient to drain it because if it is on it is by the presence of water and if when draining it you do not turn off the light you must change the entire full portfilter with everything and its electrical sensor.
