dent, which could result in death or seri-
ous injury. Have the vehicle inspected by
your Lexus dealer immediately if this
occurs.

WARNING
■Cautions during setting up the dis-
play
As the hybrid system needs to be operat-
ing during setting up the display, ensure
that the vehicle is parked in a place with
adequate ventilation. In a closed area
such as a garage, ex haust gases includ-
ing harmful carbon monoxide (CO) may
collect and enter the vehicle. This may
lead to death or a serious health hazard.

1253-2. Opening, closing and locking the doors and trunk
LS500h_OM_(U)_1809

Before driving
take some time to unlock the doors.
• The electronic key has been left in an area of approximately 6 ft. (2 m) of the
outside of the vehicle for 10 minutes or
longer.
• The smart access system with push-but-
ton start has not been used for 5 days or
longer.
●If the smart access system with push-but-
ton start has not been used for 14 days or
longer, the doors cannot be unlocked at
any doors except the driver’s door. In this
case, take hold of the driver’s door han-
dle, or use the wireless remote control or
the mechanical key, to unlock the doors.
■Turning an electronic key to bat-
tery-saving mode
When battery-saving mode is set, battery
depletion is minimized by stopping the elec-
tronic key from re ceiving radio waves.
Press twice while pressing and holding . Confirm that the electronic key indica-
tor flashes 4 times.
While the battery-saving mode is set, the
smart access system with push-button start
cannot be used. To cancel the function,
press any of the electronic key buttons.
■Conditions affe cting operation
The smart access system with push-button
start uses weak radio waves. In the following
situations, the communication between the
electronic key and the vehicle may be
affected, preventing the smart access sys-
tem with push-button start, wireless remote
control and immobilizer system from oper-
ating properly. (Ways of coping: P.443)
●When the electronic key battery is
depleted
●Near a TV tower, electric power plant,
gas station, radio stat ion, large display, airport or other fac
ility 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 metal-
lic 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 other wireless keys (that emit radio
waves) are being used nearby
●When carrying the electronic key
together with the following devices that
emit radio waves
• Another vehicle’s electronic key or a wireless key that emits radio waves
• Personal computers or personal 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
●When the electronic key is placed near a
battery charger or electronic devices
●When the vehicle is parked in a pay park-
ing spot where radio waves are emitted.
■Note for the entry function
●Even when the electronic key is within the
effective range (detection areas), the sys-
tem may not operate properly in the fol-
lowing cases:
• The electronic key is too close to the win- dow or outside door handle, near the
ground, or in a high place when the doors
are locked or unlocked.
• The electronic key is near the ground or in a high place, or too close to the center
of the rear bumper when the trunk is
opened.
• The electronic key is on the instrument panel, rear package tray or floor, or in the
door pockets or glove box when the
hybrid system is started or power switch

3 Gradually release the brake pedal
and gently depress the accelerator
pedal to accelerate the vehicle.
■Stopping
1 With the shift position in D, depress
the brake pedal.
2 If necessary, set the parking brake.
If the vehicle is to be stopped for an
extended period of time, shift the shift posi-
tion to P. ( P.178)
■Parking the vehicle
1 With the shift position in D, depress
the brake pedal to stop the vehicle
completely.
2 If the parking brake is in manual
mode, set the parking brake.
(P.183)
3 Shift the shift position to P.

4
Press the power switch to stop the
hybrid system.
5 Slowly release the brake pedal.
6 Lock the door, making sure that you
have the electronic key on your
person.
If parking on a hill, block the wheels as
needed.
■Starting off on a steep uphill
1 Make sure that the parking brake is
set and shift the shift position to D.
Hill-start assist control will operate.
( P.302)
2 Gently depress the accelerator
pedal.
3 Release the parking brake.
■For fuel-efficient driving
Keep in mind that hybr id vehicles are similar
to conventional vehicles, and it is necessary
to refrain from activi ties such as sudden
acceleration. ( P.307)
■Driving in the rain
●Drive carefully when it is raining, because
visibility will be reduced, the windows
may become fogged-up, and the road
will be slippery.
●Drive carefully when it starts to rain,
because the road surface will be espe-
cially slippery.
●Refrain from high speeds when driving on
an expressway in the rain, because there
may be a layer of wa ter between the tires
and the road surface, preventing the
steering and brakes from operating prop-
erly.
■Engine speed while driving
In the following conditions, the engine
speed may become high while driving. This
is due to automatic up-shifting control or
down-shifting implementation to meet driv-
Driving the vehicle
The following procedures should be
observed to ensure safe driving:
Driving procedure

1724-2. Driving procedures
LS500h_OM_(U)_1809
1Stop the vehicle completely.
2 If the parking brake is in manual
mode, set the parking brake.
(P.183)
3 Shift the shift position to P.
(P.178)
Check that the shift position indicator
shows P and the parking brake indicator is
illuminated.

The hybrid system will stop, and the meter
display will be extinguished (the shift posi-
tion indicator will be extinguished a few
seconds after the meter display).
5 Release the brake pedal and check
that “ACCESSORY” or “IGNI-
TION ON” is not shown on the
meter.
■Automatic P position selection function
 P.179
Modes can be changed by pressing
the power switch with the brake pedal
released. (The mode changes each
time the switch is pressed.)
■Symptoms indicating a malfunction
with the power switch
If the power switch seems to be operat-
ing somewhat differently than usual, such
as the switch sticking slightly, there may
be a malfunction. Contact your Lexus

Stopping the hybrid system
WARNING
■Stopping the hybrid system in an
emergency
●If you want to stop the hybrid system in
an emergency while driving the vehi-
cle, press and hold the power switch
for more than 2 seconds, or press it
briefly 3 times or more in succession.
(  P.416)
However, do not touch the power
switch while driving except in an emer-
gency. Turning the hybrid system off
while driving will not cause loss of
steering or braking control, however,
power assist to the st eering will be lost.
This will make it more difficult to steer
smoothly, so you should pull over and
stop the vehicle as soon as it is safe to
do so.
●If the power switch is operated while
the vehicle is running, a warning mes-
sage will be shown on the multi-infor-
mation display and a buzzer sounds.
●When restarting the hybrid system
after an emergency shutdown, press
the power switch.
