Battery-saving function
In the following circumstances, the entry func tion is disabled in order to prevent the
vehicle and electronic key batteries from discharging. ●
When the entry function has not been used for 2 weeks or more ●
When the electronic key has been left within approximately 3 ft. (1 m) of the
vehicle for 10 minutes or more
The system will resume operation when... ●
The vehicle is locked using th e door handle lock switch.●
The vehicle is locked/unlocked using the wireless remote control function
(  P. 48) or the mechanical key. (  P. 8 6 7 )■
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. 4 3 )●
The battery becomes depleted even if the electronic key is not used because
the key always receives radio waves. If the smart access system with push-but-
ton start or the wireless remote control function does not operate, or the detec-
tion area becomes smaller, the battery may be depleted. Replace the battery
when necessary. (  P. 7 8 0 )●
To avoid serious deterioration, do not leave the electronic key within 3 ft. (1 m) 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
• Induction cookers
• Table lamps

To operate the system properly
Make sure to carry the electronic key wh en 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 corr ectly 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 back door is locked or unlocked.
• The electronic key is on the instrument panel, floor or in the glove box when
the engine is started or “ENGINE ST ART 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 con-
ditions, it may be detected by the an tenna outside the cabin and the door will
become lockable from the outside, poss ibly 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 th e 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 60 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 electronic key
is near the vehicle, there is a possibility that the door may not be unlocked by the
entry function. (Use the wireless re mote control to unlock the doors.)●
A sudden approach to the effective range or door handle operation may pre-
vent the doors from being unlocked. In this case, return the door handle to the
original position and check that the d oors unlock before pulling the door han-
dle.
