Red Bull will use KERS at next weekend’s Malaysian grand prix.
The reigning champions did not have the energy-recovery system fitted to their RB7 cars in Melbourne as Sebastian Vettel strolled to pole position and the win.
But team boss Christian Horner said: "We will run KERS in Malaysia.
"It was a very marginal decision not to run it (in Australia)," he told the Guardian. "In Malaysia there is a long run to the first turn and we are keen to get it on the car there."
Championship leader Vettel, however, has mixed thoughts. He told Bild newspaper that KERS is a "fundamental tool" this year that is worth "three to five tenths per lap".
"We’re working on having it on the car," he added.
But in Auto Motor und Sport, the 23-year-old is quoted as saying: "It’s expensive, complicated and not green."
Vettel flew to Bali for a holiday after winning on Sunday.
