Position 1

Position 1 should be chosen on steep uphill gradients to avoid frequent upshifting and downshifting which could cause overheating of the transmission fluid. This position should also be selected when maximum engine braking is required on extremely steep downhill gradients.
If the selector lever is moved from position D to position 1, the transmission will immediately downshift to 3rd gear. Downshifting to 2nd gear occurs at about 115 km/hr and to 1st gear at about 60 km/hr. Manual downshifting must not be carried out at speeds above 150 km/hr. In position 1 all other gears are blocked.
