Battery-saving function
The battery-saving function will be activated in order to prevent the elec-
tronic key battery and the vehicle battery from being discharged while the
vehicle is not in operation for a long time.
In the following situations, the smart entry & start system may take some
time to unlock the doors.
• The electronic key has been left in an area of approximately 2 m (6 ft.)
of the outside of the vehicle for 10 minutes or longer.
• The smart entry & start system has not been used for 5 days or longer.
If the smart entry & start system has not been used for 14 days or longer,
the doors cannot be unlocked at any doors except the driver door. In this
case, take hold of the driver door handle, or use the wireless remote con-
trol or the mechanical key, to unlock the doors.
Electronic key battery depletion
The standard battery life is 1 to 2 years.
If the battery becomes low, an alarm will sound in the cabin when the
engine stops. (P. 46)
Since the electronic key receives radio waves all the time, the key battery
will be depleted even when the electronic key is not being used. If any of
the following problems occurs, it is assumed that the key battery has
been depleted. Replace it with a new battery.
• The smart entry & start system or wireless remote control does not
work
• The operating range has narrowed
• The electronic key LED light does not come on
To prevent the electronic key battery from being depleted significantly, do
not place the key within 1 m (3 ft.) of the following electrical appliances
that produce magnetism.
•TVs
• Personal computers
• Mobile and cordless phones, and their battery chargers
• Lamps
• Induction cookers
To operate the system properly
Make sure to carry the electronic key when operating the system.

Note for electronic key operation
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 conditions of the electronic key, the key may not be detected cor-
rectly and the system may not operate properly. (The alarm may go off
accidentally, or the door lock prevention may not function.)
Even when the electronic key is within the effective range (detection
areas), the system may not operate properly in the following cases.
• When locking or unlocking the doors, the electronic key is too close to
a door window or door handle, near the ground, or in a high place.
• The electronic key is on the instrument panel, interior floor, or in a door
pocket.
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.
Special note for smart entry & start system
When the electronic key is in the operating range, anyone can lock and
unlock the doors even without having the electronic key. However, the
unlocking operation will not be active at a door that has not detected the
electronic key.
When the electronic key is in the operating range and the door handles
get soaked with water due to car washing or heavy rain, the doors may
be locked or unlocked. If the doors are unlocked, the doors will automati-
cally be locked again when no door operations occur in approximately 30
seconds.
If the electronic key is inside or near the vehicle and if the doors are
locked using the wireless remote control, the doors may not be unlocked
with the smart entry & start system. In this case, unlock the doors using
the wireless remote control.

Note for door locking operation
When touching a lock sensor to lock the doors while wearing gloves, the
response may be slow or the doors may not be locked. In this case,
touch the lock sensor without wearing a glove.
When door handles get wet while washing the vehicle with the electronic
key on your person, the doors may be locked and unlocked repeatedly. In
this case, keep the electronic key 2 m (6 ft.) or more away from the vehi-
cle while washing (pay attention to key theft).
When the electronic key is inside the vehicle and door handles get wet
due to a car wash, interior and exterior alarms may sound. In this case,
lock the doors to stop the alarms.
A lock sensor covered with ice, snow or mud may not work properly. In
this case, remove the ice, snow or mud from the lock sensor surface and
then touch the sensor again, or unlock the doors using the lock sensor
located on the lower edge of the door handle.
Fingernails may come into contact with a door when taking hold of a door
handle. Be careful not to damage the door surface or your fingernails.
Note for door unlocking operation
The doors may not be unlocked when a door handle is operated quickly,
or if you suddenly enter the operating range of the exterior antenna and
operate a door handle. In this case, return the door handle to its original
position, unlock the doors again, and then check that the doors are
unlocked before pulling the door handle.
When taking hold of a door handle while wearing gloves, the unlocking
response may become slow or the doors may not be unlocked.
If there is another electronic key in the operating range, the response
time to unlock the doors after a door handle is taken hold of may become
longer.
When the vehicle is not driven for extended periods
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 disabled. (P. 459)
Security feature
If a door is not opened within approximately 30 seconds after the vehicle is
unlocked, the security feature automatically locks the vehicle again.

Alarms and warning indicators
A combination of exterior and interior alarms as well as warning lights are
used to prevent theft of the vehicle and unforeseeable accidents resulting
from erroneous operation. Take appropriate measures for the warning light
that comes on. (P. 401)
The following table describes circumstances and correction procedures
when only alarms are sounded.
Note for vehicle battery disconnection and reconnection
When the doors are attempted to be unlocked by means of the smart
entry & start system just after the vehicle battery has been reconnected,
it may fail. In this case, use the wireless remote control or mechanical
key to unlock and lock the doors.
The first engine start since the last time the vehicle battery was recon-
nected may fail. The engine will start from the 2nd attempt, so it is not a
malfunction.

vehicle memory. Therefore, after the vehicle battery is reconnected, the
vehicle will return to the state before the battery was disconnected. When
the battery needs to be disconnected, turn the “ENGINE START STOP”
switch OFF before disconnecting the battery.
If the “ENGINE START STOP” switch status before the vehicle battery
was disconnected is unknown, pay due attention to the vehicle when the
battery is reconnected.
