tronic key from re
ceiving radio waves.

holding .
Confirm that the elec tronic key indicator
flashes 4 times. While the battery-saving

■Conditions affe cting operation
The smart access system with push-button
start, wireless remote control and immobi-
lizer system use 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, wire-
less remote control and immobilizer system
from operating properly. (Ways of coping:
 P.412)
●When the electronic key battery is
depleted
●Near a TV tower, electric power plant,
gas station, radio stat ion, large display,
airport or other faci lity that generates
strong radio waves or electrical noise
●When the electronic key is in contact
with, or is covered by the following metal-
lic 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 ke ys (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
devices
• Another vehicle’s 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
■Note for the entry function
●Even when the electronic key is within the
effective range (detection areas), the sys-
tem may not operate properly in the fol-
lowing cases:
• The electronic key is too close to the win-
dow 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
opened.
• The electronic key is on the instrument panel, luggage room, 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 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 po ssible to start the
hybrid system if the el ectronic key is near
the window.
