When the driver depresses the pedal beyond the resistance where the detent is felt (above 85% WOT), the pedal will easily reach WOT and kickdown shift will occur accordingly. For additional information, refer to the individual vehicle?s Owner?s Manual under section ?Driving Your Vehicle? ? Automatic Transmission (Drive).
PS4812017-08-02. Service bulletin. ENGINE; POWER TRAIN.

This automatic transmission is unlike the conventional automatic transmission found in the complete line up of Kia vehicles. The new DCT improves fuel efficiency and can also provide a sportier feel. Certain aspects of this technology may lead to customer concerns if they are unfamiliar with it. To help maximize owner satisfaction on this new technology, Kia would like all dealership sales and service personnel to be familiar with the characteristics of this new transmission.
