2-1. Driving procedures CAUTION n When taking a nap in the vehicle Always turn the hybrid system off. Otherwise, you may accidentally move the shift lever or depress the accelerator pedal, which could cause an accident or fire due to hybrid system overheating. Additionally, if the vehicle is parked in a poorly ventilated area, exhaust gases may collect and enter the vehicle, leading to death or a serious health hazard. n When braking the vehicle l When the brakes are wet, drive more cautiously. Braking distance increases when the brakes are wet, and may cause one side of the vehicle to brake differently than the other side. Also the parking brake may not securely hold the vehicle. l If the power brake assist function does not operate, do not follow other vehicles closely and avoid downhill or sharp turns that require braking. In this case, braking is still possible, but it will require more force on the pedal than usual. Braking distance may also increase. l The brake system consists of 2 individual hydraulic systems: if one of the systems fails, the other will still operate. In this case, the brake pedal should be depressed more firmly than usual and braking distance becomes longer. Do not drive your vehicle with only a single brake system. Have your brakes fixed immediately. 2 When driving 161 PRIUS_U (OM47685U) DVD
