Default Can't accelerate with full power

Hello guys.

I'm new Lexus GS 450h (2008) owner and I have one question:

I've been trying full acceleration but in the dashboard I see that it only reaches 150kw.

Hybrid power mode is turned on.
Sport mode is turned on.
I've tried it with charged battery (green)
Any ideas why it doesn't reach 250kw? I saw many videos on youtube where they easily reach full power.

Can it depend on weather conditions? Right now it's pretty cold where I am (around -5 degrees of Celsius).

I hope you understood my question.

Thanks in advance!

Press de pedal acceleration harder(not a joke!), when the pedal is pressed all the way down, there is a button, you need to press the pedal harder to press that button to, if the pedal is not pressed hard with the button engaged, the car won't pass 150kw, but with that button pressed... magic happens.
It is like a kickdown button but in our cars it act like a full power button.
Sometimes it won't reach 250 kw, it will go to 230 if it's cold outside, because the batteries are not in temperature.
