To back up, lift up on the shift selector ring 1 and then move it to the R (Reverse) position after stopping the vehicle completely. The shift selector ring 1 returns to its original position when the shift selector is moved to the N (Neutral) position. If it is difficult to move the shift selector into R (Reverse) or 1 (1st), shift into N (Neutral), then release the clutch pedal. Depress the clutch pedal again and shift into R (Reverse) or 1 (1st). Suggested maximum speed in each gear Downshift to a lower gear if the engine is not running smoothly, or if you need to accelerate. Do not exceed the maximum suggested speed (shown below) in any gear. For level road driving, use the highest gear suggested for that speed. Always observe posted speed limits, and drive according to the road conditions, which will ensure safe operation. Do not over-rev the engine when shifting to a lower gear as it may cause engine damage or loss of vehicle control.
