2-1. Driving procedures CAUTION l Do not under any circumstances shift the shift lever to P, R or N while the vehicle is moving. Doing so can cause significant damage to the transmission system and may result in a loss of vehicle control. l Do not shift the shift lever to N while the vehicle is moving. Doing so may cause the engine brake to not operate properly and lead to an accident. l Do not turn the engine off while driving. The power steering and brake booster systems will not operate properly if the engine is not running. l Use engine braking (downshift) 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. 171) l When stopped on an inclined surface, use the brake pedal and parking brake to prevent the vehicle from rolling backward or forward and causing an accident. l Do not adjust the position 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 that may result in death or serious injury. l Always check that all passengers' arms, heads or other parts of their bodies 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 highspeed 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. 2 When driving 159
