adjusts to give maximum control
during the highest level of spirited
driving.
Transmission Shift Mode
Sport or Track –Dynamic
Performance Mode (DPM) allows the
transmission to hold the current gear after a quick release of a heavily
applied accelerator pedal. This
provides greater engine braking and
enhanced vehicle control without
using the paddles. DPM recognizes
aggressive cornering, heavy braking,
and high acceleration to select and
