moderated. Automatic transmission
Overview
The automatic transmission adapts to your
individual driving style by continuously
adjusting its shift points. These shift point
adjustments take into account the current
operating and driving conditions. If the operating or driving conditions change, the
automatic transmission reacts by adjusting
the gearshift program.
The automatic transmission selects the
individual gears automatically. This depends
on:
R
the selector lever position D with shift
ranges 4, 3, 2 and 1(Y page 115)
R the position of the accelerator pedal
R the road speed
The selector lever
position or the current shift
range is shown in the display. Display on
vehicles with steering wheel buttons
(Y page 77) and without steering wheel
buttons ( Y page 73).
When the selector lever is in position D, you
can influence the gearshifts made by the
automatic transmission. You can restrict the
shift range or you can perform gearshifts
yourself. Automatic transmission
