7-10 Starting and operating downshifting to a lower gear when accelerating again. This prevents repeated upshifting and downshifting resulting in a smoother operation of the vehicle. Selector lever reverse inhibiting function This function prevents accidental movement of the selector lever to the "R" position while the vehicle is moving. The function becomes operational when the vehicle reaches a speed of approximately 6 mph (10 km/h). Once operational, it prevents the selector lever from being moved from the "N" position to the "R" position. When the vehicle speed drops below 6 mph (10 km/h), the function is canceled. The selector lever can then be moved to the "R" and "P" positions. When the ignition switch has been turned to the "OFF" position, movement of the selector lever from the "N" position to the "R" position is possible for a limited time period and then becomes impossible. Also, the selector lever cannot be moved to the "R" position when it has been placed in the "P" position and then placed again in the "N" position. When movement of the selector lever from the "N" position to the "R" position has become impossible, turn the ignition switch back to the "ON" position then move the selector lever to the "P" position. Pressing the selector lever release button also makes it possible to move the selector lever to the "P" position at this time. Do not drive the vehicle with the selector lever in the "N" (neutral) position. Engine braking has no effect in this condition and the risk of an accident is consequently increased. D (Drive) This position is for normal driving. The transmission automatically shifts into a suitable gear from 1st to 5th according to the vehicle speed and the acceleration you require. When more acceleration is required in this position, press the accelerator pedal fully to the floor and hold that position. The transmission will automatically downshift to 4th, 3rd, 2nd or 1st gear. When you release the pedal, the transmission will return to the original gear position. To use the SPORT mode, move the lever from this position into the manual gate. To use the manual mode, move the lever from this position into the manual gate then move it toward the "+" and "-" ends. While climbing a grade When driving up a hill, undesired upshift to 4th or 5th gear is prevented from taking place when the accelerator is released. This minimizes the chance of subsequent NOTE The transmission may downshift to 2nd or 1st gear, depending on the way the accelerator pedal is pressed to accelerate the vehicle again. While going down a hill When you are descending a hill or any other slope while braking with the "SPORT" mode selected, the transmission may downshift to 4th or 3rd gear depending on how hard you depress the brake pedal, causing engine braking to work. Reacceleration for a short time will cause the transmission to upshift normally. NOTE A 5th-to-4th automatic downshift will not occur at speeds above 78 mph (126 km/h) and a 4th-to-3rd automatic downshift will not occur at speeds above 53 mph (86 km/h). Automatic downshifts to 4th or 3rd may occur even when driving on a level road depending on conditions, such as how hard you depress the brake pedal.
