On downhill roads TRANSMISSION TRANSAXLE 6 36 ELECTRONICALLY CONTROLLED AUTOMATIC TRANSMISSION A4Q this control ensures that moderate engine braking force is produced even if gears are shifted down to 3rd gear e The condition of an uphill or downhill road is determined by comparing the actual acceleration calculated from the vehicle speed with the vehicle acceleration on a level road calculated from the throttle opening vehicle speed and gear used e If it is determined that the road slopes up shifting up to 4th gear and locking up gears are restricted e When the brakes are applied on a road that is judged to slope down gears are shifted down to 3rd gear e To give priority to the driver s intention uphill and downhill gear shift control is exercised only when the shift lever is in the D position andjthe O D switch is set to ON O D OFF lamp Squat Control e If gears are shifted from the P to D 2 or L position to start the vehicle with the throttle fullyfclosedJand the brakes applied gears are shifted temporarily to the 2nd position N 2nd Ist to prevent the vehicle from squatting down because of an abrupt change in torque Fail Safe Function e If an error occurs in the signal input output system of the gear shift control computer the fail safe function enables the computer to con tinue control to minimize degradation in driving performance e When the system has recovered from an error the fail safe safe function is deactiv
