| PS496 | 2017-08-25. Service bulletin. PITSTOP: CUSTOMER TIP: ACCELERATOR PEDAL FUNCTION/DESCRIPTION - On all K900 (KH), Cadenza (VG, YG), and Optima (JF, JFa, JF-HEV, JF-PHEV) vehicles, the accelerator pedal features a small detent with a spring to provide increased resistance to help avoid unnecessary fuel consumption when applying full throttle. 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). |
