2-1. Driving procedures CAUTION l Do not drive the vehicle over or stop the vehicle near flammable materials. The exhaust system and exhaust gases can be extremely hot. This may cause a fire if there is any flammable material nearby. l Do not let the vehicle roll backwards while the shift lever is in a driving position, or roll forward while the shift lever is in R. Doing so may cause the engine to stall or lead to poor brake and steering performance, resulting in an accident or damage to the vehicle. l If the smell of exhaust is noticed inside the vehicle, open the windows and check that the back door is closed. Large amounts of exhaust in the vehicle can cause driver drowsiness and an accident, resulting in death or a serious health hazard. Have the vehicle inspected by your Toyota dealer immediately. l Do not under any circumstances shift the shift lever to P or R 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 insufficient engine braking 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. 170) 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 the vehicle off-road. This is not a AWD vehicle designed for real off-road driving. Proceed with all due caution if it becomes unavoidable to drive off-road. 2 When driving 161
