HYBRID OVERVIEW RX 400h Driving the RX 400h On the whole, driving the RX 400h is not very much different from driving a conventional vehicle. However, there are some subtle differences you will notice. • Turning the ignition key "starts" the vehicle, but may not start the engine. Like starting a regular vehicle, turn the ignition key to the "START" position and release to start the vehicle. After a few seconds, the "READY" light in the Power Gauge will come on.
HYBRID OVERVIEW RX 400h Driving the RX 400h (continued) • Some parking attendants may not be familiar with the RX 400h. To properly operate the vehicle, these basic tips are important: 1. Turn key to “START” and release. 2. Begin driving when “READY” light stays on. 3. The engine will start and stop automatically. New RX 400h vehicles come with parking attendant key ring tabs, with these tips in English and Spanish. • When refueling, the fuel door may take a few moments to open.
HYBRID OVERVIEW RX 400h The Benefits of Lexus Hybrid Technology Impressive Performance • Lexus hybrid vehicles deliver impressive throttle response, even from a standing start. This is because the electric motors deliver maximum torque instantly. • The Lexus Hybrid Drive system combined with the ECVT (Electronically controlled Continuously Variable Transmission) helps deliver smooth, seamless acceleration for excellent passing performance and drivability.
RX 400h HYBRID OVERVIEW The Benefits of Lexus Hybrid Technology (continued) Reduced Emissions • Lexus hybrid vehicles produce 70% fewer smog-forming emissions than the average new vehicle and are certified as an SULEV (Super Ultra-Low Emission Vehicle) by the California Air Resources Board. • The gasoline engine is turned off much of the time during idle and acceleration, which means that zero emissions are being produced.
RX 400h HYBRID OVERVIEW 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. Each year, the EPA provides the data to the Department of Energy, which publishes the results at www.

HYBRID OVERVIEW RX 400h Frequently Asked Questions Q: How should I choose between an RX 350 and an RX 400h hybrid? A: If most of your driving is highway cruising or you leave your vehicle parked for several weeks at a time, the RX 350 may best meet your needs. If most of your driving is stop-and-go city and you want improved acceleration and fuel economy, the RX 400h may best meet your needs.
HYBRID OVERVIEW RX 400h Frequently Asked Questions (continued) Q: Do you have to charge it/plug it in? A: Lexus Hybrid Drive automatically recharges the 12-volt and hybrid batteries using regenerative braking or by running the engine to generate electricity. However, if the vehicle has been parked for a long time, the 12-volt and the hybrid battery will discharge gradually. For parking longer than about 30 days, charging of the 12-volt battery may be required. See your dealership for details.
