HiVec H-matic is an adaptive transmission with a manual control function, which is installed on many Hyundai models. It is based on a classic automatic gearbox with a hydraulic torque converter and 4, 5, or 6 speeds. The adaptation function allows customising the transmission operation to the maximum possible extent, which improves the vehicle dynamics, ensures quick gear shifting, increases driving safety, and reduces fuel consumption.
To switch to the manual mode, shift the gear selector into a special slot that may be marked as “Sports mode”. Push the selector to “+” for upshifting and to “-” for downshifting. A short double push of the selector to the “-” position allows the driver to skip one gear. Manual control makes the car more sportive, improves its handling and dynamics when doing certain manoeuvres, and performance on slippery roads.
