Red Bull expect Sebastian Vettel to help team mate Mark Webber win the Formula One world championship should the situation arise but will not be ordering him to do so.
After Red Bull clinched the constructors' title in Brazil with a race to spare team principal Christian Horner said he trusted his drivers to act in the team's best interests.
Webber is eight points behind Ferrari's Fernando Alonso with 25 to be won in the Abu Dhabi season-ender on Sunday.
Vettel, who led a one-two finish at Interlagos, is a further seven adrift.
A repeat of the Brazil podium would gift the crown to Alonso whereas a Webber-Vettel one-two would make the Australian his country's first champion since Alan Jones 30 years ago.
