Conditions affecting operation

The smart key system uses weak 

radio waves. In the following situa-

tions, the communication between 

the electronic key and the vehicle 

may be affected, preventing the 

smart key system, wireless remote 

control and immobilizer system from 

operating properly. (Ways of coping: 



P.527)

●

When the electronic key battery is 

depleted

●

Near a TV tower, electric power 

plant, gas station, radio station, 

large display, airport or other facil-

ity 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 con-

tact with, or is covered by the fol-

lowing metallic objects

• Cards to which aluminum foil is 

attached

• Cigarette boxes that have alumi-

num 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 electronic key or a wire-

less key that emits radio waves

• Personal computers or personal 

digital assistants (PDAs)

• Digital audio players

• Portable game systems

●

If window tint with a metallic con-

tent or metallic objects are 

attached to the rear window

●

near a battery charger or elec-

tronic devices

●

When the vehicle is parked in a 

pay parking spot where radio 

waves are emitted.

■

Note for the entry function

●

Even when the electronic key is 

within the effective range (detec-

tion areas), the system may not 

operate properly in the following 

cases:

• The electronic key is too close to 

the window or outside door han-

dle, 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 center of the rear 

bumper.

• The electronic key is on the instru-

ment panel, or 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 out-

side the cabin and the doors 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. However, only the 

doors detecting the electronic key 

can be used to unlock the vehicle.

●

Even if the electronic key is not 

inside the vehicle, it may be possi-

ble to start the hybrid system if the 

electronic key is near the window.

●

The doors may unlock or lock if a 

large amount of water splashes on 

the door handle, such as in the 

rain or in a car wash, when the 

electronic key is within the effec-

tive range. (The doors will auto-

matically be locked after 

approximately 60 seconds if the 

131

3-2. Opening, closing and locking the doors and tailgate

Before 

driving

doors are not opened and closed.)

●

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 remote 

control to unlock the doors.)

●

Touching the door lock sensor 

while wearing gloves may delay or 

prevent lock operation.

●

When the lock operation is per-

formed using the lock sensor, rec-

ognition signals will be shown up 

to two consecutive times. After 

this, no recognition signals will be 

given.

●

If the door handle becomes wet 

while the electronic key is within 

the effective range, the door may 

lock and unlock repeatedly. In this 

case, follow the following correc-

tion procedures to wash the vehi-

cle:

• Place the electronic key in a loca-

tion 6 ft. (2 m) or more away from 

the vehicle. (Take care to ensure 

that the key is not stolen.)

• Set the electronic key to battery-

saving mode to disable the smart 

key system. (



P.129)

●

If the electronic key is inside the 

vehicle and a door handle 

becomes wet during a car wash, a 

message may be shown on the 

multi-information display and a 

buzzer will sound outside the vehi-

cle. To turn off the alarm, lock all 

the doors.

●

The lock sensor may not work 

properly if it comes into contact 

with ice, snow, mud, etc. Clean 

the lock sensor and attempt to 

operate it again.

●

A sudden approach to the effec-

tive range or door handle may pre-

vent the doors from being 

unlocked. In this case, return the 

door handle to the original position 

and check that the doors unlock 

before pulling the door handle 

again.

●

If there is another electronic key in 

the detection area, it may take 

slightly longer to unlock the doors 

after the door handle is gripped.

■

When the vehicle is not driven 

for extended periods

●

To prevent theft of the vehicle, do 

not leave the electronic key within 

6 ft. (2 m) of the vehicle.

●

The smart key system can be 

deactivated in advance.

●

Setting the electronic key to bat-

tery-saving mode helps to reduce 

key battery depletion. (



P.129)

■

To operate the system properly

●

Make sure to carry the electronic 

key when operating the system. 

Do not get the electronic key too 

close to the vehicle when operat-

ing the system from the outside of 

the vehicle.

Depending on the position and hold-
ing condition of the electronic key, 
the key may not be detected cor-
rectly and the system may not oper-
ate properly. (The alarm may go off 
accidentally, or the door lock pre-
vention function may not operate.)
