■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 pushbutton
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 function will be activated
in order to prevent the electronic 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
access system with push-button start may
take some time to unlock the doors.
- The electronic key has been left within
approximately 6 ft. (2 m) of the outside of
the vehicle for 10 minutes or longer.
- The smart access system with push-button
start has not been used for 5 days or
longer.
- If the smart access system with push-button
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 handle,
or use the wireless remote control or
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 battery-
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 system
with push-button start, wireless remote
control and immobilizer system from operating
properly.
- 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 electrical noise
- When the electronic key is in contact
with, 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
- Portable radio, cellular phone, cordless
phone or other wireless communication
device
- Another electronic key or a wireless key
that emits radio waves
- Personal computers or personal digital
assistants (PDAs)
- Digital audio players
- Portable game systems
- 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 parking
spot where radio waves are emitted.
■Notes 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 center
of the rear bumper when the trunk is
opened.
- The electronic key is on the instrument
panel, rear package 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
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 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.
- 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
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 will 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.
- Unlocking the vehicle may take more
time if another electronic key is within the
effective range.
- 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:
- 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.
- 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.
■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 system with push-button
start can be deactivated in advance.
- Battery-saving mode can reduce the
power consumption of electronic keys.
■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 function may not operate.)
- Do not leave the electronic key inside the
trunk.
The key confinement prevention function
may not operate, depending on the location
of the key (close to a spare tire, the
inside edge of the trunk), conditions
(inside a metal bag, close to metallic
objects) and the radio waves in the surrounding
area.
■If an electronic key does not work properly
- Locking and unlocking the doors and
opening the trunk
- Starting the hybrid system
■Customization
Settings (e. g. smart access system with
push-button start) can be changed.
If the smart access system with push-button
start has been deactivated in a customized
setting, refer to the explanations for the following
operations.
- Locking and unlocking the doors and
opening the trunk:
Use the wireless remote control or
mechanical key.
- Starting the hybrid system and changing
power switch modes
- Stopping the hybrid system
