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.
•
To start 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 extra care while driving.

Some parking attendants may not be familiar with the LS 600h L.
•
To properly 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 followingwill help keep your vehicle’s 12-volt battery fully charged:
Drivevehicle at least weekly. Operate accessories with vehicle in “READY” mode.
When parking, make sure doors and trunk are closed and lights are turned off.
Long-term parking.
•
If the vehiclehas beenparked for a long time, the 12-voltand the hybrid battery
will discharge gradually. For parking longer than about 30 days, charging of the
12-volt battery may be required. Your Lexus dealer has details. To keep the hybrid
batteryin good condition,drive the vehicleat least once every several months for at
least30minutesorten miles.If the hybrid batterybecomesfully dischargedand the
vehicle will not start, even witha jump start to the 12-volt battery, contact your
Lexus dealer.

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.

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.

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.fueleconomy.gov.
Some quick facts about EPA estimated fuel economy tests:
Federal law requires EPA estimated 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.

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 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.
• Driving at highway speeds above 60 mph.
• Driving on hilly or mountainous terrain and unpaved roads. (EPA tests
assume flat roads.)
• Short trips cause the engine to run more as a percentage of driving,
as it warms the emissions system.
• Carrying extraweight. (The EPAtest 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.
