2-1. Driving procedures CAUTION l Do not select shift position R when the vehicle is rolling forward, do not select D when moving in reverse, and do not press the P position switch before the vehicle stops fully. Doing so will cause the buzzer to sound and the shift position to change to N. In addition, excessive force will be applied to the powertrain and damage may result. l Do not change the shift position to N while the vehicle is moving. Doing so may cause insufficient engine braking, resulting in an accident. l Do not turn the hybrid system off while driving. The power steering and brake actuator will not operate properly if the hybrid system is off. l Use engine braking (shift position B) to maintain a safe speed when driving down a steep hill. Using the brakes continuously may cause the brakes to overheat and lose effectiveness. (→P. 155) l Do not adjust the positions of the steering wheel, the seat, or the inside or outside rear view mirrors while driving. Doing so may result in a loss of vehicle control that can cause accidents, resulting in death or serious injury. l Always check that all passengers' arms, heads or other parts of their body are not outside the vehicle, as this may result in death or serious injury. l Do not drive in excess of the speed limit. Even if the legal speed limit permits it, do not drive over 85 mph (140 km/h) unless your vehicle has high-speed capability tires. Driving over 85 mph (140 km/h) may result in tire failure, loss of control and possible injury. Be sure to consult a tire dealer to determine whether the tires on your vehicle are high-speed capability tires or not before driving at such speeds. n When driving on slippery road surfaces l Sudden braking, acceleration and steering may cause tire slippage and reduce your ability to control the vehicle, resulting in an accident. l Abrupt changes from shift position D to B and rapid changes in the engine speed could cause the vehicle to skid, resulting in an accident. l After driving through a puddle, lightly depress the brake pedal to make sure that the brakes are functioning properly. Wet brake pads may prevent the brakes from functioning properly. If the brakes on only one side are wet and not functioning properly, steering control may be affected, resulting in an accident. 142
