Before driving■If “Key Detected in Vehicle” is shown on
the multi-information display
An attempt was made to lock the doors
using the smart access system with push-
button start while the electronic key was still
inside the vehicle. Retrieve the electronic
key from the vehicle and lock the doors
again.
■Battery-saving function
The battery-saving fu nction will be acti-
vated in order to prevent the electronic key
battery and the 12-volt battery from being
discharged while the vehicle is not in opera-
tion for a long time.
●In the following situations, the smart
access system with pu sh-button start may
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 battery-
saving mode
●When battery-saving mode is set, battery
depletion is minimized by stopping the
electronic key from receiving radio
waves.
Press twice while pressing and
holding .
Confirm that the electronic key indicator
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.
●Electronic keys that will not be used for
long periods of time can be set to the bat-
tery-saving mode in advance.
■Conditions affecting 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.403)
●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

inside
• Metallic wallets or bags
•Coins
• Hand warmers made of metal
• Media such as CDs and DVDs
●When other wireless ke ys (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

●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 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
conditions, 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 electron ic 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.
●Even if the electronic
key is not inside the
vehicle, it may be po ssible to start the
hybrid system if the el ectronic 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 effective
range. (The doors wi ll automatically be
locked after approximately 60 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 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.
●When the lock operation is performed
using the lock sensor, recognition signals
will be shown up to two consecutive
times. After this, no recognition signals
will be given.
●If the door handle becomes wet while the
electronic key is within the effective
range, the door may lock and unlock
repeatedly. In that case, follow the follow-
ing 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.125)
●If the electronic key is inside the vehicle
and a door handle becomes wet during a
car wash, a buzzer may sound outside the
vehicle and “Key Detected in Vehicle”
may be shown on the multi-information
display. 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.
●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 longer
to unlock the doors after the door handle
is gripped.
■When the vehicle is not driven for
extended periods
●To prevent theft of the vehicle, do not
leave the electronic key within 6 ft. (2 m)
of the vehicle.
●The smart access syst em with push-but-
ton start can be deactivated in advance.
●Setting the electronic key to battery-sav-
ing mode helps to reduce key battery
depletion. ( P.125)
■To operate the system properly
Make sure to carry the electronic key when
operating the system. Do not get the elec-
tronic 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 preven-
tion may not operate.)

■Recall procedure
1
Make sure that the doors are
locked before recalling the driving
position. Carry the electronic key
that has been registered to the driv-
ing position, and then unlock and
open the driver’s door using the
smart access system with push-but-
ton start or wireless remote control.
The driving position will move to the
recorded position (not including the steer-
ing wheel and head-up display [if
equipped]). However, the seat will move to
a position slightly behind the recorded
position in order to make entering the vehi-
cle easier.
If the driving position is in a position that
has already been recorded, the seat and
outside rear view mirrors will not move.
2Turn the power switch to ACC or
ON, or fasten a seat belt.
The seat, steering wheel and head-up dis-
play (if equipped) will move to the
recorded position.
■Recalling the driving position using the
memory recall function
●Different driving positions can be regis-
tered for each electronic key. Therefore,
the driving position that is recalled may
be different depending on the key being
carried.
●If a door other than the driver’s door is
unlocked with the smart access system
with push-button start, the driving posi-
tion cannot be recalled. In this case, press
the driving position button which has
been set.
■Customization
The unlock door settings of the memory
recall function can be customized. (Cus-
tomizable features: P.439)

between the temperature of the outside
air and that of the windshield can cause
the outer surface of the windshield to fog
up, blocking your vision.
■When the outside rear view mirror
defoggers are operating
Do not touch the outside rear view mir-
ror surfaces, as they can become very
hot and burn you.
