Operation of each component
LS600hL_U(OM50E41U)
■Battery-saving function
In the following circumstances, the entry function is disabled in order to prevent the
12-volt battery from discharging and the electronic key battery from depleting.
●When the entry function has not been used for 30 days or more
●When the electronic key has been left within approximately 6 ft. (2 m) of the vehi-
cle for 10 minutes or more
The system will resume operation when
●The vehicle is locked using the door handle lock switch when carrying the elec-
tronic key on your person.
●The vehicle is locked/unlocked using the wireless remote control function.
(  P. 141)
●The vehicle is locked/unlocked using the mechanical key. ( P. 5 2 4 )

1343-2. Opening, closing and locking the doors and trunk
LS600hL_U(OM50E41U)
■Conditions affecting operation
The smart access system with push-button start uses weak radio waves. In the follow-
ing situations, the communication between the electronic key and the vehicle may be
affected, preventing the smar t access system with push-button start, wireless remote
control and immobilizer system from operating properly. (Ways of coping: P. 5 2 4 )
●When the electronic ke y battery is depleted
●Near a TV tower, electric power plant, gas station, radio station, large display, air-
port or other facility that generates strong radio waves or electrical noise
●When carrying a portable radio, cellular phone, cordless phone or other wireless
communication device
●When the electronic key is in contact with, or is covered by the following metallic
objects
• Cards to which aluminum foil is attached
• Cigarette boxes that have aluminum foil inside
• Metallic wallets or bags
•Coins
• Hand warmers made of metal
• Media such as CDs and DVDs
●When multiple electronic keys are in the vicinity
●When other wireless keys (that emit radio waves) are being used nearby
●When carrying the electronic key togeth er with the following devices that emit
radio waves
• Another vehicle’s electronic key or a wireless key that emits radio waves
• Personal computers or person al digital assistants (PDAs)
• Digital audio players
• Portable game systems
●If window tint with a metallic content or metallic objects are attached to the rear
window

■Electronic key battery depletion
●The standard battery life is 1 to 2 years. (The card key battery life is about a year and
a half.)
●If the battery is low, an alarm will sound in the cabin when the hybrid system is
started or stopped. ( P. 1 3 0 )
●The battery becomes depleted even if the electronic key is not used because the
key always receives radio waves. If the smart access system with push-button start
or the wireless remote control does not operate, or the detection area becomes
smaller, the battery may be depleted. Replace the battery when necessary.
(  P. 4 7 2 )
●To avoid serious deterioration, do not leave the electronic key within 3 ft. (1 m) of
the following electrical appliances that produce a magnetic field:
•TVs
•Personal computers
• Cellular phones, cordless phones and battery chargers
• Recharging cellular phones or cordless phones
•Table lamps
• Induction cookers
■When the electronic key battery is fully depleted

LS600hL_U(OM50E41U)
CAUTION
■Trunk easy closer
■Power trunk opener and closer
Observe the following precautions when operating the power trunk opener and
closer.
Failure to do so may cause serious injury.
●Check the safety of the surrounding area to make sure there are no obstacles or
anything that could cause any of your belongings to get caught.
●If anyone is in the vicinity, make sure they are safe and let them know that the
trunk is about to open or close.
●If the trunk closer switch is pressed whil e the trunk lid is opening during automatic
operation, the trunk lid stops opening. Take extra care when on an incline, as the
trunk lid may open or close suddenly.
●On an incline, the trunk lid may suddenly shut after it opens automatically. Make
sure the trunk lid is fully open and secure before using the trunk.
●In the following situations, the power trunk opener and closer may detect an
abnormality and automatic operation may be stopped. In this case, the trunk lid
has to be operated manually. Take extra care in this situation, as the stopped trunk
lid may suddenly shut, causing an accident.
• When the trunk lid contacts an obstacle
• When the 12-volt battery voltage suddenly drops, such as when the power switch is turned to ON mode or the hybrid system is started during automatic
operation
●Do not attach any accessories other than genuine Lexus parts to the trunk lid. The
power trunk opener and closer may not op erate, causing itself to malfunction, or
the trunk lid may suddenly shut again after it is opened.
In the event that the trunk lid is left slightly
open, the trunk easy closer will automatically
close it to the fully closed position. It takes
several seconds before the trunk easy closer
begins to operate. Be careful not to catch fin-
gers or anything else in the trunk lid, as this
may cause bone fractures or other serious
injuries.

2004-1. Before driving
LS600hL_U(OM50E41U)
■Drum-in-disc type parking brake system
Your vehicle has a drum-in-disc type parking brake system. This type of brake system
needs bedding-down of the brake shoes peri odically or whenever the parking brake
shoes and/or drum are replaced. Have your Lexus dealer perform the bedding
down operation.
■Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the availability of the
correct fuel. ( P. 5 5 0 )
■For efficient use
●Shift the shift lever to D when driving.
In the N position, the gasoline engine oper ates but electricity cannot be generated.
The hybrid battery (traction battery) will discharge, requiring unnecessary engine
power to recharge.
●Drive your vehicle smoothly.
Avoid abrupt acceleration and decelerati on. Gradual acceleration and decelera-
tion will make more effective use of the electric motor (traction motor) without hav-
ing to use gasoline engine power.
●Avoid repeated acceleration.
Repeated acceleration consumes hybrid ba ttery (traction battery) power, resulting
in poor acceleration. Battery power can be restored by driving with the accelerator
pedal slightly released.
●Shift the shift lever to P when parking.
In the N position, the hybrid battery (traction battery) does not recharge.
Leaving the shift lever in the N position for an extended period of time may dis-
charge the hybrid battery (traction batter y). The vehicle cannot run if the hybrid
battery (traction battery) is discharged.

again automatically cancels the steering lock.
■When the steering lock cannot be released
■Steering lock motor overheating prevention
To prevent the steering lock motor from ov erheating, the motor may be suspended if
the hybrid system is turned on and off repeatedly in a short period of time. In this
case, refrain from operating the hybrid sy stem. After about 10 seconds, the steering
lock motor will resume functioning. The green indicator light on the power switch
will flash and a message will be shown on the
multi-information display. Press the power
switch again while turning the steering wheel
left and right.

CAUTION
■When starting the hybrid system
Always start the hybrid system while sitting in the driver’s seat. Do not depress the
accelerator pedal while starting the hybrid system under any circumstances.
Doing so may cause an accident resulting in death or serious injury.
■Caution while driving
If hybrid system failure occurs while the vehicle is moving, do not lock or open the
doors until the vehicle reaches a safe and complete stop. Activation of the steering
lock in this circumstance may lead to an accident, resulting in death or serious
injury.
■Stopping the hybrid system in an emergency
If you want to stop the hybrid system in an emergency while driving the vehicle,
press and hold the power switch for more th an 2 seconds, or press it briefly 3 times
or more in succession. ( P. 485)
However, do not touch the power switch while driving except in an emergency.
Turning the hybrid system off while driving will not cause loss of steering or braking
control, however, power assist to the steering will be lost. This will make it more dif-
ficult to steer smoothly, so you should pull over and stop the vehicle as soon as it is
safe to do so.
