■When riding in an aircraft
When bringing an electronic key onto an aircraft, make sure you do not press any but-
tons on the electronic key while inside the aircraft cabin. If you are carrying an electronic
key in your bag etc., ensure that the buttons are not likely to be pressed accidentally.
Pressing a button may cause the electronic key to emit radio waves that could interfere
with the operation of the aircraft.
■Electronic key battery depletion

half.)
●If the battery becomes low, an alarm will so und in the cabin when the hybrid system is
stopped. ( →P. 5 4 2 )
●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 elec-
tronic key battery may be depleted. Replace the battery when necessary. ( →P. 4 8 8 )
• The smart entry & start system or the wireless remote control does not operate.

In this case, the trunk lid can be opened pressing the trunk release button on the trunk
lid.
●If the spare electronic key is put in the trunk with all the doors locked, the key confine-
ment prevention function is activated so the trunk can be opened. In order to prevent
theft, take all electronic keys with you when leaving the vehicle.
●If the electronic key is put in the trunk with all the doors locked, the key may not be
detected depending on the location of the key and the surrounding radio wave condi-
tions. In this case, the key confinement prevention function cannot be activated, causing
the doors to lock when the trunk is closed. Make sure to check where the key is before

■Note for the entry function (if equipped)
●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 theground, 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.
●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 and the doors 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. However, only the doors detecting the electronic key can be used
to unlock the vehicle.
●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 key is within the effective range.
(The doors will automatically be locked af ter approximately 30 seconds 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 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 electronic key is within the effective range,
the door may lock and unlock repeatedly. In this case, follow the following correction
procedures to wash the vehicle:
• Place the electronic key in a location 2 m (6 ft.) 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 entry & start sys- tem. ( →P. 1 5 0 )
●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 handle operation or a handle operation immediately after entering the effec-
tive range may prevent the doors from being unlocked. Touch the door unlock sensor
and check that the doors are unlocked before pulling the door handle again.
●Unlocking the vehicle may take more time if another electronic key is within the effec-
tive range.

CAUTION
■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 provide, 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 th at can assist the driver in low-visibility con-
ditions. It is still necessary for the driver to pay close attention to the vehicle’s sur-
roundings.
●Assisting the driver in making correct judgment
When attempting to estimate the possibility of a collision, the only data available to
the pre-crash safety system is that from obstacles it has detected directly in front of
the vehicle. Therefore, it is absolutely nece ssary 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 is not capable of automatically avoiding a collision or bring-
ing the vehicle to a stop safely without appropriate operations performed by the
driver. 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.
