Alarms and warning messages
A combination of exterior and interior alarms as well as warning messages
shown on the multi-information display is used to prevent theft of the vehi-
cle and accidents resulting from erroneous operation. Take appropriate mea-
sures in response to any warning message on the multi-information display.
(P. 565)
The following table describes circumstances and correction procedures
when only alarms are sounded.
Security feature
P. 8 1
Battery-saving function
The battery-saving function will be activated in order to prevent the elec-
tronic key battery and the 12-volt battery from being discharged while the
vehicle is not in operation for a long time.
In the following situations, the smart entry & start system may take some
time to unlock the doors.
• The electronic key has been left in an area of approximately 2 m (6 ft.)
of the outside of the vehicle for 10 minutes or longer.
• The smart entry & start system has not been used for 5 days or longer.

Note for the unlocking function
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. Remove the gloves and touch the sensor on the back of the handle
again.
If the door handle becomes wet while the electronic key is within the
effective range, the door may lock and unlock repeatedly. Place the key
in a position 2 m (6 ft.) or more separate from the vehicle while the vehi-
cle is being washed. (Take care to ensure that the key is not stolen.)
If there is another electronic key in the detection area, it may take
slightly longer to unlock the doors after the door handle is gripped.
Fingernails may scrape against the door during operation of the door
handle. Be careful not to injure fingernails or damage the surface of the
door.
When the vehicle is not driven for extended periods
To prevent theft of the vehicle, do not leave the electronic key within 2 m
(6 ft.) of the vehicle.
The smart entry & start system can be deactivated in advance. (P. 655)
Alarm
Using the smart entry & start system to lock the doors will set the alarm sys-
tem. (P. 138)
To operate the system properly
Make sure to carry the electronic key when operating the system. Do not get
the electronic key too close to the vehicle when operating the system from
the outside of the vehicle.
Depending on the position and holding condition of the electronic key, the
key may not be detected correctly and the system may not operate properly.
(The alarm may go off accidentally, or the door lock prevention may not
operate.)

cover, floor or in the glove box when the hybrid system is started or
“POWER” switch modes are changed.
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.

tem.
(P. 138)
Conditions affecting operation
The smart entry & start system, wireless remote control and immobilizer
system use weak radio waves. In the following situations, the communica-
tion between the electronic key and the vehicle may be affected, preventing
the smart entry & start system, wireless remote control and immobilizer sys-
tem from operating properly.
(Ways of coping: P. 617)
When the electronic key battery is depleted
Near a TV tower, electric power plant, gas station, radio station, large
display, airport or other facility that generates strong radio waves or elec-
trical noise
When carrying a portable radio, cellular phone, cordless phone or other
wireless communication devices
When the electronic key is in contact with, or is covered by the follow-
ing 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

about a year and a half.)
If the battery becomes low, an alarm will sound in the cabin when the
hybrid system stops. (P. 577)
As the electronic key always receives radio waves, the battery will
become depleted even if the electronic key is not used. The following
symptoms indicate that the electronic key battery may be depleted.
Replace the battery when necessary. (P. 515)
• The smart entry & start system or the wireless remote control does not
operate.
• The detection area becomes smaller.
• The LED indicator on the key surface does not turn on.

(3 ft.) 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
• Glass top ranges
• Table lamps
