Switching the door unlock function
It is possible to set which doors the entry function unlocks.
Turn the “ENGINE START STOP” switch OFF.
Cancel the intrusion sensor of the alarm system to prevent unin-
tended triggering of the alarm during the setting change. (P. 97)
When the indicator on the key surface is turned off, push and
hold or for approximately 5 seconds while pushing
on the key.
The setting changes each time an operation is performed, as shown below.
(When changing the setting continuously, release the buttons, wait for at
least 5 seconds, and repeat step 3.)
To prevent unintended triggering of the alarm, unlock the doors using the
wireless remote control and open and close a door once after the settings
have been changed. (If a door is not opened within 30 seconds after is
pressed, the doors will be locked again and the alarm will automatically be
set.)
In case that the alarm is triggered, immediately stop the alarm. (P. 9 7 )

Battery-saving function
In the following circumstances, the entry function is disabled in order to
prevent the vehicle and electronic key batteries from discharging.
When the entry function has not been used for 30 days or more
When the electronic key has been left within approximately 1 m (3 ft.) of
the vehicle for 10 minutes or more
The system will resume operation when...
The vehicle is locked using the door handle lock switch.
The vehicle is locked/unlocked using the wireless remote control func-
tion.
(P. 52)
The vehicle is locked/unlocked using the mechanical key. (P. 458)
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
engine stops. (P. 440)
The battery becomes depleted even if the electronic key is not used
because the key always receives radio waves. If the smart entry & start
system or the wireless remote control does not operate, or the detection
area becomes smaller, the battery may be depleted. Replace the battery
when necessary.
(P. 388)
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
• Glass top ranges
• Table lamps

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
function.)
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 trunk is unlocked.
• The electronic key is on the instrument panel, rear package tray or
floor, or in the glove box when the engine is started or “ENGINE
START STOP” 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 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 engine 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. (The doors will automatically
be locked after approximately 30 seconds if the doors are not opened and
closed.)
Gripping the door handle when wearing a glove may not unlock the
door.
If the wireless remote control is used to lock the doors when the elec-
tronic 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.)
A sudden approach to the effective range or door handle operation may
prevent the doors from being unlocked. In this case, return the door han-
dle to the original position and check that the doors unlock before pulling
the door handle again.
