hold of the driver’s door handle, or use

the wireless remote control or the

mechanical key, to unlock the doors.

■

Conditions affecting operation

The smart entry & start system, wireless

remote control and engine immobilizer sys-

tem use weak radio waves. In the following

affected, preventing the smart entry & start

system, wireless remote control and engine

immobilizer system from operating prop-

erly. (Ways of coping:

■

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 compartment, 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 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 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 when

the electronic key is within the effective

range. (The door will automatically be

locked after approximately 30 seconds if

the 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. Remove the gloves and touch

the lock sensor again.

●

If the door handle becomes wet while the

electronic key is within the effective

range, the door may lock and unlock

repeatedly. In that case, follow the follow-

ing correction procedures to wash the

vehicle:

• Place the electronic key in a location 2 m

(6 ft.) 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 entry & start

system. (



P.121)

●

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 vehicle. 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 effective

range or door handle may prevent 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.

●

Fingernails may scrape against the door

during operation of the door handle. Be

careful not to injure fingernails or dam-

age the surface of the door.

■

When the vehicle is not driven for

extended periods

●

To prevent theft of the vehicle, do not

leave the electronic key within 2 m (6 ft.)

of the vehicle.

●

The smart entry & start system can be

deactivated in advance.

●

Setting the electronic key to battery-sav-

ing mode helps to reduce key battery

depletion. (

■

To operate the system properly

Make sure to carry the electronic key when

operating the system. Do not get the elec-

tronic 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 correctly and the system

may not operate properly. (The alarm may

go off accidentally, or the door lock preven-

tion may not operate.)

■

If the smart entry & start system does

not operate properly

●

If the doors cannot be locked or unlocked

and the back door cannot be opened,

perform the following.

• Bring the electronic key close to the door

handle and perform a lock or unlock

operation.

• Bring the electronic key close to the but-

ton on the back door (



P.105, 109) and

press the button.

• Use the wireless remote control.
If the doors cannot be locked or unlocked
by perform the above, use the mechanical

WARNING

■

Caution regarding interference with

electronic devices

●

People with implantable cardiac pace-

makers, cardiac resynchronization

therapy-pacemakers or implantable

cardioverter defibrillators should

maintain a reasonable distance

between themselves and the smart

entry & start system antennas.

(



P.120)

The radio waves may affect the opera-

tion of such devices. If necessary, the

entry function can be disabled. Ask

any authorized Lexus retailer or Lexus

authorized repairer, or any reliable

repairer for details, such as the fre-

quency of radio waves and timing of

the emitted radio waves. Then, consult

your doctor to see if you should disa-

ble the entry function.

●

Users of any electrical medical device

other than implantable cardiac pace-

makers, cardiac resynchronization

therapy-pacemakers or implantable

cardioverter defibrillators should con-

sult the manufacturer of the device for

information about its operation under

the influence of radio waves.

Radio waves could have unexpected

effects on the operation of such medi-

cal devices.

WARNING

■

When adjusting the seat position

●

Take care when adjusting the seat

position to ensure that other passen-

gers are not injured by the moving

seat.

●

Do not put your hands under the seat

or near the moving parts to avoid

injury. Fingers or hands may become

jammed in the seat mechanism.

stuck.

■

Seat adjustment

To reduce the risk of sliding under the lap

belt during a collision, 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.
