2-1. Driving procedures CAUTION n When taking a nap in the vehicle Always turn the hybrid system off. Otherwise, if you accidentally move the shift lever or depress the accelerator pedal, this 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 l When the brakes are wet, drive more cautiously. 2 Braking distance increases when the brakes are wet, and this 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 When driving 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 others will still operate. In this case, the brake pedal should be depressed more firmly than usual and the braking distance will increase. If this happens, do not continue to drive the vehicle. If the brake system warning light (red indicator) comes on while driving, immediately stop the vehicle in a safe place and contact your Lexus dealer. NOTICE n When driving the vehicle l Do not depress the accelerator and brake pedals at the same time during driving. If the brake pedal is depressed while driving with the accelerator pedal depressed, driving torque may be restrained. l Do not use the accelerator pedal or depress the accelerator and brake pedals at the same time to hold the vehicle on a hill. n When parking the vehicle Be sure to firmly apply the parking brake and set the shift position to P. Failure to do so may cause the vehicle to move or the vehicle may accelerate suddenly if the accelerator pedal is accidentally depressed. 145
