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

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.
