That is a safety feature and is normal.

Okay,first thank you for your patience... i know that is a normal function of the truck, but my question is, in the day must turn on the lights that are under the headlights? and in the night must be the headlights?

Thank you for your patiences. I appologize, but I'm still confused. I am unable to read what you wrote on the lights. As far as the driving lights, they should be on all of the time when the park brake is off. At night, you neet to turn the headlights on.

I am sorry if this still doesn't answer the question. Let me know.

But, when the parking brake is applied, the headlights are off. I can turn them on manually.

The headlights are the safty driving lights during the day in all Canadian made vehicles. Also several states are using them that way.
