■System maintenance
The vehicle has a maintenance-free type
engine immobilizer system <immobilizer system>.
■Conditions that may cause the system to malfunction
●If the grip portion of the key is in contact with a metallic object
●If the key is in close proximity to or touch-ing a key registered to the security sys-
tem (key with a built-in transponder chip) of another vehicle
Engine immobilizer system
<Immobilizer system>
The vehicle’s keys have built-in tran-

■Battery-saving function
The battery-saving function will be acti-
vated in order to prevent the electronic key battery and the 12-volt battery from being discharged while the vehicle is not in opera-
tion 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 within
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 the passen-ger door. In this case, push the depres-
sion on the front edge of the driver’s door handle, or use the wireless remote con-trol or mechanical key, to unlock the
doors.
■Turning an electronic key to battery- saving mode
When battery-saving mode is set, battery depletion is minimized by stopping the elec-
tronic key from receiving radio waves.
Press twice while pressing and
holding . Confirm that the elec-
tronic key indicator flashes 4 times.
While the battery-saving mode is set, the smart entry & start system cannot be used. To cancel the function, press any of the elec-
tronic key buttons.
■Conditions affecting operation
The smart entry & star t system uses weak radio waves. In the following situations, the
communication between the electronic key and the vehicle may be affected, preventing
the smart entry & start system, wireless remote control and engine immobilizer sys-tem <immobilizer syst em> from operating
properly. (Ways of coping: P.389)
●When the electronic key battery is
depleted
●Near a TV tower, electric power plant,
gas station, radio station, large display, airport or other facility that generates strong radio waves or electrical noise
●When carrying a portable radio, cellular phone, cordless phone or other wireless
communication device
●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 keys (that emit radio waves) are being used nearby
●When carrying the electronic key
together with the following devices that emit radio waves• 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.
