■Alarms and warning indicators
An alarm sounds and warning message displa ys shown on the multi-information display
are used to protect against unexpected accidents or theft of the vehicle resulting from
erroneous operation. When a warning messag e is displayed, take appropriate measures
based on the displayed message. ( →P. 509)
When only an alarm sounds, circumstances and correction procedures are as follows.
■Battery-saving function
The battery-saving function w ill be activated in order to prevent the electronic key bat-
tery and the vehicle 12-volt battery from being discharged while the vehicle is not in
operation for a long time.
●In the following situations, the smart acce ss system with push-button start may take
some time to unlock the doors.
• The electronic key has been le ft 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-button st art has not been used for 5 days or lon-
ger.
●If the smart access system with push-button start has not been used for 14 days or lon-
ger, the doors cannot be unlocked at any doors except the driver’s door. In this case,
take hold of the driver’s d oor handle, or use the wireless remote control or the mechan-
ical key, to unlock the doors.

Operation of each component
■Electronic Key Battery-Saving Function
When battery-saving mode is set, battery depletion is minimized by stopping the elec-
tronic key from receiving radio waves.
■Conditions affecting operation
The smart access system with push-button st art uses weak radio waves. In the following
situations, the communication between the electronic key and the vehicle may be
affected, preventing the smar t access system with push-but ton start, wireless remote
control and immobilizer system from operating properly. (Ways of coping: → P. 525)
●When the electronic key battery is depleted
●Near a TV tower, electric power plant, gas st ation, radio station, large display, airport or
other facility that generates strong radio wave s or electrical noise
●When carrying a portable radio, cellular phone, cordless phone or other wireless com-
munication device
●When the electronic key is in contact wi th, 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 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 person al digital assistants (PDAs)
• Digital audio players
• Portable game systems
●If window tint with a metallic content or me tallic objects are attached to the rear win-
dow
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.

ES300h_OM_OM33D45U_(U)3-2. Opening, closing and
locking the doors and trunk
■Note for the entry function
●Even when the electronic key is within the effective range (detection areas), the system
may not operate properly in the following cases:
• The electronic key is too close to the window 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 rear
bumper center when the trunk is opened.
• The electronic key is on th e instrument panel, rear pack age tray or floor, or in the
door pockets or glove box when the hybrid system is started or power switch modes
are changed.
●Do not leave the electronic key on top of th e instrument panel or near the door pockets
when exiting the vehicle. Depending on the radio wave reception conditions, it may be
detected by the antenna outside the cabin an d the doors will become lockable from the
outside, possibly trapping the electronic key inside the vehicle.
●As long as the electronic key is within th e effective range, the doors may be locked or
unlocked by anyone. However, only the door s detecting the electronic key can be used
to unlock the vehicle.
●Even if the electronic key is not inside the vehicle, it may be possible to start the hybrid
system if the electronic key is near the window.
●The doors may unlock or lock if a large amou nt of water splashes on the door handle,
such as in the rain or in a car wash when the electronic ke y is within the effective range.
(The doors will automatically be locked af ter approximately 60 seconds if the doors
are not opened and closed.)
●If the wireless remote control is used to lo ck the doors when the electronic key is near
the vehicle, there is a possibility that the d oor may not be unlocked by the entry func-
tion. (Use the wireless remote control to unlock the doors.)
●Touching the door lock or unlock sensor while wearing gloves may prevent lock or
unlock operation.
●If the door handle becomes wet while the el ectronic key is within the effective range,
the door may lock and unlock repeatedly. In that case, follow the following correction
procedures to wash the vehicle:
• Place the electronic key in a location 6 ft. (2 m) or more away from the vehicle. (Take care to ensure that the key is not stolen.)
• Set the electronic key to battery-saving mode to disable the smart access system with push-button start. ( →P. 123)
●If the electronic key is inside the vehicle and a door handle becomes wet during a car
wash, a message may be shown on the mult i-information display and a buzzer will
sound outside the vehicle. To turn off the alarm, lock all the doors.
●The lock sensor may not work properly if it comes into contact with ice, snow, mud, etc.
Clean the lock sensor and attempt to operate it again, or use the lock sensor on the
lower part of the door handle.
●A sudden approach to the effective range or door handle may prevent the doors from
being unlocked. In this case, return the door handle to the original position and check
that the doors unlock before pulling the door handle again.
●Gripping the door handle when wearing a glove may not unlock the door.
●If there is another electronic key in the de tection area, it may take slightly longer to
unlock the doors after the door handle is gripped.
