Giancarlo Fisichella does not expect his Force India team to run their McLaren-Mercedes kinetic energy recovery system until the Spanish Grand Prix in May.
The Italian has also come out against the KERS devices, agreeing with those who feel the systems are unsafe and too expensive.
Fisichella, who tested Force India's new VJM02 for the first time at Jerez this morning, said he had not used KERS yet and did not expect to for some time.
"We're not going to use the KERS till Barcelona so I just need to concentrate on driving the car as quick as possible," he told reporters.
He doesn't think this will be a disadvantage as he suspects few teams will use KERS in the opening four races.
"Most of the teams I think are going to run with it from the European races, so not for three or four races," said Fisichella.
He admitted that he is an opponent of KERS and had major misgivings about the system.
"I never drove with it, and I am against it because the teams are spending a lot of time and especially money to develop it. It's still not safe," Fisichella said.
"It's strange to see a driver jumping from the seat to the ground like a monkey. The safety issue is not perfect. We had some problems with the BMW mechanics (last year).
"I am against (KERS) because it's not safe and they are spending a lot of money."
