Page 2: Hybrid System
4.0-liter V8 engine. • The Lexus RX 400h does not need to be plugged in like an electric car. The HSD system automatically charges itself. • The Lexus RX 400h hybrid system provides the high level of performance associated with Lexus, along with improved gas mileage and reduced emissions.

How the system works, the system’ s components and what they do. Frequently Asked Questions 21 - 22 A wide range of questions often asked about the RX 400h and hybrid technology. RX 400h Hybrid Specifications Specifications pertaining to the hybrid system.
Page 4: Driving The Rx400H
The RX 400h can drive up to 15 to 20 miles per hour on electric power alone, so the gasoline engine may not start for a while depending upon the need.
Page 5 Running out of fuel. • Do not run your RX 400h out of fuel. The RX 400h is not designed to be operated with the fuel tank empty. If you try to start the RX 400h with the fuel tank empty, the hybrid system will become disabled on the third attempt. If you continue to drive with the fuel tank empty, the hybrid battery will rapidly discharge and the hybrid system will shut down.
Page 6: Hybrid Luxury Driving Performance
V8 engine. In fact, the "400" in RX 400h stands for the power output of the 3.3 L engine and hybrid battery which, when combined, approximate the power of a 4.0 liter V8 engine.
Page 7 Traditional gasoline-powered vehicles may suffer from decreased performance at higher altitudes where there is less oxygen in the air. Because the power output of the hybrid battery is not directly affected by altitude, the RX 400h's acceleration performance can be less affected by altitude than a conventional vehicle.
Page 8: Epa Milieage Estimates & Fuel Economy
RX 400h EPA Mileage Estimates & Fuel Economy Quick Facts - EPA Mileage Estimates The EPA estimated fuel economy numbers are derived from vehicle testing conducted at the U.S. Environmental Protection Agency’ s (EPA’ s ) National Vehicle and Fuel Emissions Laboratory in Ann Arbor, Michigan. Vehicle manufacturers also submit test results based on strict EPA standardized drive patterns.
Page 9 There are many factors which may cause your actual mileage with the RX 400h, or other vehicles, to vary from the EPA estimates: • Quick acceleration and heavy braking may reduce mileage by as much as 33% in highway driving and as much as 5% in city driving.

Page 22 RX 400h Hybrid Technology ® Lexus Hybrid Synergy Drive main components (continued) Hybrid Battery – Composed of sealed nickel-metal hydride modules, the 288-volt hybrid battery is located under the rear seat. It supplies power to the electric motors during start-up, acceleration, uphill driving, and reverse.
Page 23 RX 400h Hybrid Technology ® How Lexus Hybrid Synergy Drive (HSD) works. Lexus Hybrid Synergy Drive(HSD) incorporates gas-engine power with electric motor efficiency in a seamless manner. Typically, the system works as follows: Starting from a stop The front electric motor/generator (MG2) and the rear electric motor/generator (MGR*) both drive the vehicle.
