B 2 (Second) To shift from the "3" to "2" position, push the release button. This position is for using engine braking when going down a hill or for climbing a steep grade. In this position, the transmission holds in the 2nd gear. Use this position when starting off from a standstill on slippery road surfaces such as mud or snow. It will ensure greater traction. B 1 (First) This position is for driving up or down very steep grades, or driving through mud or sand, or on slippery surfaces. In this position, the transmission holds in the 1st gear. B Maximum speeds WARNING When shifting down a gear, ensure that the vehicle is not travelling at a speed exceeding the Maximum Allowable Speed for the gear which is about to be selected. Failure to observe this precaution can lead to engine over-revving and this in turn can result in engine damage. In addition, sudden application of engine brakes when the vehicle is travelling on a slippery surface can lead to wheel locking; as a consequence, control of the vehicle may be lost and the risk of an accident increased. The following tables show the maximum speeds that are possible with each different gear. The tachometer's (if so equipped) needle will enter the red area if these speeds are exceeded. When shifting down a gear, it is important to confirm that the current vehicle speed is not in excess of the Maximum Allowable Speed of the gear which is about to be selected. Exceeding the Maximum Allowable Speeds will result in over-revving of the engine. In addition a powerful engine brake will engage and control of the vehicle may be lost. 7-18
