Upshifting
In manual drive program M, the automatic
transmission does not shift up
automatically even when the engine
limiting speed for the current gear is
reached. When the engine limiting speed is
reached, the fuel supply is cut to prevent
the engine from overrevving. Always make
sure that the engine speed does not reach
the red area of the tachometer. There is
otherwise a risk of engine damage.
Pull the right-hand steering wheel paddle
shifter.
The automatic transmission shifts up to the next gear.
Before the engine speed reaches the red area, an upshift indicator appears in the multifunction display.
