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 becomes low, an alarm will sound in the cabin when the hybrid
system stops. (P. 589)

depleted even if the electronic key is not used. The following symptoms indi-
cate that the electronic key battery may be depleted. Replace the battery when
necessary. (P. 530)
• The smart entry & start system or the wireless remote control does not oper-
ate.

• The LED indicator on the key surface does not turn on.
To avoid serious deterioration, do not leave the electronic key within 1 m (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
• Induction cookers
• Table lamps
Replacing the battery

Effective range (areas within which the electronic key is detected)
Alarms and warning messages
A combination of exterior and interior alarms as well as warning messages
shown on the multi-information display are used to prevent theft of the vehicle
and accidents resulting from erroneous operation. Take appropriate measures in
response to any warning message on the multi-information display. (P. 575)
The following table describes circumstances and correction procedures when
only alarms are sounded.When locking or unlocking the doors
(vehicles with entry function)
The system can be operated when the
electronic key is within about 0.7 m
(2.3 ft.) of either of the outside front
and back door handles. (Only the doors
detecting the key can be operated.)
When starting the hybrid system or
changing power switch modes
The system can be operated when the
electronic key is inside the vehicle.

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 back door is opened.
• The electronic key is on the instrument panel, luggage room, 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 the instrument panel or near the door
pockets when exiting the vehicle. Depending on the radio wave reception con-
ditions, it may be detected by the antenna outside the cabin and the door will
become lockable from the outside, possibly trapping the electronic key inside
the vehicle.
As long as the electronic key is within the effective range, the doors may be
locked or unlocked by anyone.
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 if a large amount of water splashes on the door handle,
such as in the rain or in a car wash when the electronic key is within the effec-
tive range. (The door will automatically be locked after approximately 30 sec-
onds if the doors are not opened and closed.)
If the wireless remote control is used to lock the doors when the electronic key
is near the vehicle, there is a possibility that the door may not be unlocked by
the entry function. (Use the wireless remote control to unlock the doors.)
Touching the door lock sensor while wearing gloves may delay or prevent lock
operation. Remove the gloves and touch the lock sensor 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 vehicle is being washed.
(Take care to ensure that the key is not stolen.)
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 multi-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.
If there is another electronic key in the detection area, it may take slightly lon-
ger 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
Vehicles with entry function: 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. 650)
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 out-
side 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.)
If the smart entry & start system does not operate properly
Locking and unlocking the doors: Use the mechanical key. (P. 621)
Starting the hybrid system: P. 6 2 2
Customization
Settings (e.g. smart entry & start system) can be changed.

Limitations of the pre-crash safety system
Do not overly rely on the pre-crash safety system. Always drive safely, taking
care to observe your surroundings and checking for any obstacles or other road
hazards.
Failure to do so may cause an accident resulting in death or serious injury.
Cautions regarding the assist contents of the system
By means of alarms and brake control, the pre-crash safety system is intended
to assist the driver in avoiding collisions through the process of LOOK-
JUDGE-ACT. There are limits to the degree of assistance the system can pro-
vide, so please keep in mind the following important points.
Assisting the driver in watching the road
The pre-crash safety system is only able to detect obstacles directly in front of
the vehicle, and only within a limited range. It is not a mechanism that allows
careless or inattentive driving, and it is not a system that can assist the driver
in low-visibility conditions. It is still necessary for the driver to pay close
attention to the vehicle’s surroundings.
Assisting the driver in making correct judgement
When attempting to estimate the possibility of a collision, the only data avail-
able to the pre-crash safety system is that from obstacles it has detected
directly in front of the vehicle. Therefore, it is absolutely necessary for the
driver to remain vigilant and to determine whether or not there is a possibility
of collision in any given situation.
Assisting the driver in taking action
The pre-crash safety system’s braking assist feature is designed to help reduce
the severity of a collision, and so only acts when the system has judged that a
collision is unavoidable. This system by itself is not capable of automatically
avoiding a collision or bringing the vehicle to a stop safely. For this reason,
when encountering a dangerous situation the driver must take direct and
immediate action in order to ensure the safety of all involved.
