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 engine immobilizer sys-

tem from operating properly. (Ways

of coping:



P.535)

●

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

●

When the electronic key is placed

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

engine is started or engine 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 engine if the elec-

tronic 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

129

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.127)

●

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.127)

■

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.)

WARNING

■

Caution regarding interfer-

ence with electronic devices

●

People with implantable car-

diac pacemakers, cardiac

resynchronization therapy-

pacemakers or implantable car-

dioverter defibrillators should

keep away from the smart key

system antennas. (



P.126)

The radio waves may affect the

operation of such devices. If

necessary, the entry function

can be disabled. Ask your Toy-

ota dealer for details, such as

the frequency of radio waves

and timing of the emitted radio

waves. Then, consult your doc-

tor to see if you should disable

the entry function.

●

Users of any electrical medical

device other than implantable

cardiac pacemakers, cardiac

resynchronization therapy-

pacemakers or implantable car-

dioverter defibrillators should

consult the manufacturer of the

device for information about its

operation under the influence of

radio waves.

Radio waves could have unex-

pected effects on the operation

of such medical devices.

Ask your Toyota dealer for details

on disabling the entry function.

■

Seat adjustment

●

To reduce the risk of sliding

under the lap belt during a colli-

sion, do not recline the seat

more than necessary.

If the seat is too reclined, the lap

belt may slide past the hips and

apply restraint forces directly to

the abdomen, or your neck may

contact the shoulder belt,

increasing the risk of death or

serious injury in the event of an

accident.

Adjustments should not be

made while driving as the seat

may unexpectedly move and

cause the driver to lose control

of the vehicle.
