Speaking on Friday, Nolasco said: "One of the reasons has to do with revising our sales plans due to the negative effects of the recalls.
"The other reason is that we are getting ready to build a new hybrid vehicle in our UK plant.
"In that case it is very customary to close a plant for a few days, or even a few weeks."
In early June, Toyota also plans to halt one of its two assembly lines at its Burnaston plant in Britain for another five working days, Ririko Takeuchi, a company spokeswoman said.
Toyota currently faces 138 potential class-action lawsuits over falling vehicle values and about 97 personal injury and wrongful death cases in federal courts across the US.
The company has blamed the sudden acceleration problems on floor mats and accelerators that sometimes stick.
However, most of the lawsuits from owners trace the incidents to faulty electronic throttle controls that they say Toyota has been aware of and covered up for nearly a decade.
The car maker has repeatedly denied its electronics are the cause.
