What's wrong, in plain English

In certain cold weather driving conditions, while driving in EV Mode, the computer that controls the hybrid system in your RAV4 Prime may shut the hybrid system down if you press the accelerator quickly to speed up further. When the hybrid system shuts down like this, it results in the engine stalling.
