Page 36: Hybrid System
1-1. Hybrid system Hybrid system Your vehicle is a hybrid vehicle. It has characteristics different from conventional vehicles. Be sure you are closely familiar with the char- acteristics of your vehicle, and operate with care. The hybrid system combines the use of a gasoline engine and an elec- tric motor (traction motor) according to driving conditions, improving fuel efficiency and reducing exhaust emissions.
Page 37 1-1. Hybrid system  When stopped/during start-off The gasoline engine stops when the vehicle is stopped. During start-off, the electric motor (traction motor) drives the vehicle. At slow speeds or when traveling down a gentle slope, the engine is stopped and the motor is used. ...

Page 41: Hybrid System Precautions
1-1. Hybrid system Hybrid system precautions Take care when handling the hybrid system, as it contains a high volt- age system (about 650 V at maximum) as well as parts that become extremely hot when the hybrid system is operating. Obey the caution labels attached to the vehicle.
Page 42 If the emergency shut off system activates, your vehicle will not restart. To restart the hybrid system, contact your Lexus dealer or repairer, or another duly qualified and equipped profes- sional.
Page 43 The hybrid system may not start. In that case, try to start the system again. If the “READY” indicator does not come on, contact any authorized Lexus dealer or repairer, or another duly qualified and equipped professional.
Page 44 1-1. Hybrid system CAUTION  High voltage and high temperature precautions The vehicle has high voltage DC and AC systems as well as a 12-volt sys- tem. DC and AC high voltage is very dangerous and can cause severe burns and electric shock that may result in death or serious injury.
Page 45 Do not carry large amount of water such as an aquarium into the vehicle. If water spills onto the hybrid battery (traction battery), the battery may be damaged. Have the vehicle inspected by any authorized Lexus dealer or repairer, or another duly qualified and equipped professional.

Page 281 2-4. Using other driving systems Driving in vehicle-to-vehicle distance control mode This mode employs a radar sensor to detect the presence of vehi- cles up to approximately 120 m (400 ft.) ahead, determines the cur- rent vehicle-to-vehicle following distance, and operates to maintain a suitable following distance from the vehicle ahead.
