Driving the LS 600h L

On the whole, driving the LS 600h L is not very much different from driving a conventional vehicle. However,there are some subtle differences you will notice.

Pressing the “POWER” button starts the vehicle, but may not start the engine.

Tostart the LS 600h L press and hold the brake pedal, then press the “POWER” button. After a few seconds, the "READY" light in the center of the instrument cluster will come on. Once the "READY" light comes on, place the transmission lever into the desired position and start driving. When accelerating slowly, the LS 600h L

can drive at low speeds on electric power alone, so the gasoline engine may not start for a while depending upon the need.

The transmission will feel different.

The LS 600h L uses an Electronically-controlled Continuously Variable Transmission (ECVT) with an advanced low and high range torque multiplication device. The transmission does not shift with fixed gear ratios like a conventional transmission, so it delivers power efficiently and smoothly.

The brakes may feel different.

The LS 600h L features an advanced, electronically-controlled brake-by-wire system. This system controls both the regenerative braking system and the conventional braking system. As a result, the brakes may feel different from a conventional vehicle.

The engine will turn off and on while you drive.

The engine will automatically turn on and off as needed. At medium or high speeds, it is normal for the engine to be on most of the time. At low speeds or when stopped, the engine may or may not be on, depending on the need.

You will notice different sounds while driving.

The engine sound will be more steady than a conventional vehicle when accelerating due to the smooth operation of the ECVT.It is also normal for the new technology of the Lexus Hybrid Drive to make a "whirring" sound while driving.

CAUTION: While driving a hybrid vehicle, pay special attention to the area around the vehicle. Because there is little vehicle noise in electric-only mode, pedestrians, people riding bicycles or other people and vehicles in the area may not be aware of the vehicle starting off or approaching them, so take extracare while driving.

Driving the LS 600h L (continued)

Some parking attendants may not be familiar with the LS 600h L.

Toproperly operate the vehicle, these basic tips are important:

1.Press and hold the brake pedal, then press the “POWER” button. 2. Begin driving when “READY” light stays on.

3. The engine will start and stop automatically.

New LS 600h L 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.

As part of emissions system operation, it may take up to 15 seconds for the fuel door to automatically release after the release button is pressed. The Multiinformation Display in the instrument cluster will display "Refuel Ready" when the door releases.

Running out of fuel.

Do not run your LS 600h L out of fuel. The LS 600h L is not designed to be operated with the fuel tank empty. If you try to start the LS 600h L with the fuel tank empty, the hybrid system may become disabled on the third attempt. If you continue to drive with the fuel tank empty, the hybrid battery will rapidly discharge and the vehicle will shut down. If you run out of fuel, immediately pull over to a safe location and turn off the vehicle. Be sure to add fuel before attempting to restart the vehicle or continuing to drive.

Hybrid Battery cooling vents.

Do not block the hybrid battery cooling vents located below the rear window with any items. Doing so could cause overheating of the hybrid battery.

Maintaining charge for your 12-volt battery.

The following will help keepyour vehicle’s 12-voltbattery fully charged:

Drive vehicle at least weekly.Operate accessorieswith vehiclein “READY”mode. When parking, make sure doors and trunk are closedand lightsare turned off.

Long-term parking.

If the vehicle has been parkedfor a long time, the 12-voltand the hybridbattery will dischargegradually.Forparking longer than about 30 days,chargingof the 12-volt battery may be required. YourLexus dealer has details. Tokeep the hybrid battery in goodcondition, drivethe vehicle at least onceeveryseveralmonthsfor at least 30 minutes or ten miles. If thehybrid battery becomesfullydischargedandthe vehicle will not start, evenwith a jump start to the 12-voltbattery,contactyour

Lexusdealer.

Driving the LS 600h L (continued)

What you can expect from your LS 600h L:

Responsive and smooth performance

The “D” transmission range is used for performance, normal, or economical driving. Only use the "S" transmission ranges if needed to help maintain vehicle speed when going down steep grades. The lower the range, the greater the engine braking force.

Driver-adjustable performance, the “PWR-Hybrid-SNOW” switch

The "PWR-Hybrid-SNOW" switch located on the center console has three modes:

Set to "Hybrid PWR" for increased

responsiveness. Once set, it will remain in this mode. Set to "Hybrid" Normal (center position) for balanced performance and economy. Once set, it will

remain in this mode. Toggle to "Hybrid SNOW" for more controlled acceleration on slippery surfaces. It will remain in this mode until the vehicle is turned off.

Driver-selectable “EV” drive mode switch

In EV drive mode, the electric motor,powered by the hybrid battery, is used to drive the vehicle. This mode allows you to drive without concern for gas emissions. It may not be possible to select EV drive mode

in the following situations:

The temperature of the hybrid system is low or high, or if the engine is warming up.

The hybrid battery is low (level 3 or less).

Vehicle speed is about 25 mph or more.

The accelerator pedal is depressed firmly or the vehicle is on a hill, etc.

The windshield defogger is in use.

Possible driving distance is up to about 1/2 mile at low speeds. This may also depend on the hybrid battery level and driving conditions.

Notes: If “EV” mode cannot be turned on, a buzzer will sound and a message will be shown on the multi-information display. Operating the vehicle in EV mode will not increase overall fuel economy.

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.

Low Levels of Noise, Vibration and Harshness (NVH)

Since Lexus hybrid vehicles can operate on electric power only during start-up and lower speeds, the vehicle interior NVH level is about half that of conventional gasoline-powered vehicles.

The gasoline engine does not have to be turned on in order for the electric air conditioner in Lexus hybrid vehicles to operate.

The Electric Power Steering (EPS) system eliminates the hydraulic pump associated with steering noise and vibration.

The ECVT eliminates the hesitation and noise level associated with shifting between fixed gear ratios.

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.

LS 600h L

The Benefits of Lexus Hybrid Technology (continued)

The gasoline engine is turned off much of the time during idle and deceleration, which means that zero emissions are being produced.

The gasoline engine can be smaller in size than non-hybrid vehicles, producing fewer emissions without sacrificing performance.

Improved Fuel Efficiency

By combining a hybrid battery, electric motors and engine, the Lexus Hybrid Drive system is able to reduce fuel consumption, while still delivering ample power for all types of driving situations.

The LS hybrid delivers an improved city gas mileage rating.*

Fuel consumption is zero when the engine is turned off and the vehicle is operating in electric only mode.

*Actual mileage may vary.

EPAMileage

Estimates

& Fuel Economy

Quick Facts - EPA Mileage Estimates

The EPAestimated 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 EPAstandardized drive patterns. Each year,the EPAprovides the data to the Department of Energy, which publishes the results at www.fueleconomy.gov.

Some quick facts about EPA estimated fuel economy tests:

Federal law requires EPAestimated fuel economy to be provided on a fuel economy label affixed to the window of every vehicle (see Figure 1). The EPA estimates serve as a useful guide for comparing the relative fuel efficiency of various vehicles and are intended for comparison only. Fuel economy estimates are determined under ideal laboratory conditions following a standardized test determined by federal law. Each vehicle must complete tests simulating a driving routine for:

City - Low speeds in stop-and-go urban traffic.

Highway - Free-flow traffic at highway speeds.

High Speed - Higher speeds; harder acceleration and braking.

AC - Air conditioner use under hot ambient conditions.

(See www.fueleconomy.gov for further details.)

Why you may not achieve the EPA estimates

Because the EPA fuel economy estimates are derived in ideal laboratory conditions, they are just estimates, which may not reflect real world conditions. There are many factors which may cause your actual mileage with the

LS 600h L, or other vehicles, to vary from the EPAestimates:

Quick acceleration and heavy braking may reduce mileage by as much as 33% in highway driving and as much as 5% in city driving.

Driving at highway speeds above 60 mph.

Driving on hilly or mountainous terrain and unpaved roads. (EPAtests assume flat roads.)

Short trips cause the engine to run more as a percentage of driving, as it warms the emissions system.

Carrying extra weight. (The EPA test assumes only 300 lbs. of passengers and cargo.)

Cargo racks. (Vehicles are tested without cargo racks, which can increase wind drag.)

Poor maintenance. (Vehicles tested are in top condition.)

Some fuels contain less energy than others. Using oxygenated fuels or reformulated gasoline (RFG), for example, can cause a small decrease in fuel economy.
