2-1. Driving procedures CAUTION n When taking a nap in the vehicle Always turn the engine off. Otherwise, you may accidentally move the shift lever or depress the accelerator pedal, which could cause an accident or fire due to engine 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 Do not pump the brake pedal if the engine stalls. Each push on the pedal uses up the reserve for the power-assisted brakes. 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. NOTICE n While driving the vehicle Do not use the accelerator pedal or depress accelerator and brake pedals together to hold the vehicle on a hill. n When parking the vehicle Always put the shift lever in "P". Failure to do so may cause the vehicle to move or the vehicle may accelerate suddenly if the accelerator pedal is accidentally depressed. 116
