Battery-saving function
The battery-saving function will be activated in order to prevent the electronic key bat-

tery and the vehicle battery from being discharged while the vehicle is not in operation

for a long time.

●

In the following situations, the smart access system with push-button start may take

some time to unlock the doors.
• The electronic key has been left within approximately 6 ft. (2 m) of the outside of the

vehicle for 10 minutes or longer.

• The smart access system with push-button start has not been used for 5 days or lon-

ger.

Electronic Key Battery-Saving Function
When battery-saving mode is set, battery depletion is minimized by stopping the elec-

tronic key from receiving radio waves.

■

Conditions affecting operation
The smart access system with push-button start uses 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, wireless remote

control and engine immobilizer system from operating properly.

(Ways of coping:

P. 572)

●

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 com-

munication device

●

When the electronic key is in contact with, or is covered by the following metallic

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 win-

dow

Press

twice while pressing and holding

. Confirm that the electronic key indica-

tor flashes 4 times.

While the battery-saving mode is set, the smart

access system with push-button start cannot be

used. To cancel the function, press any of the

electronic key buttons.

■

Note for the entry function

●

Even when the electronic key is within the effective range (detection areas), the system

may not operate properly in the following cases:
• The electronic key is too close to the window 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 trunk is opened.

• The electronic key is on the instrument panel, rear package tray 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 outside 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 possible to start the engine

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 effective range.

(The doors 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 func-

tion. (Use the wireless remote control to unlock the doors.)

●

Touching the door lock or unlock sensor while wearing gloves may prevent lock or

unlock operation.

●

When the lock operation is performed using the lock sensor, recognition 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 correction

procedures to wash the vehicle:
• Place the electronic key in a location 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 access system

with push-button start. (

P. 137)

●

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, or use the lock sensor on the

lower part of the door handle.

●

A sudden handle operation or a handle operation immediately after entering the effec-

tive range may prevent the doors from being unlocked. Touch the door unlock sensor

and check that the doors are unlocked before pulling the door handle again.

●

Unlocking the vehicle may take more time if another electronic key is within the effec-

tive range.

■

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 prevention function may not operate.)

●

Do not leave the electronic key inside the luggage compartment.

The key confinement prevention function may not operate, depending on the location

of the key (close to a spare tire, the inside edge of the luggage compartment), condi-

tions (inside a metal bag, close to metallic objects) and the radio waves in the surround-

ing area. (

WARNING

■

Caution regarding interference with electronic devices

●

People with implantable cardiac pacemakers, cardiac resynchronization therapy-

pacemakers or implantable cardioverter defibrillators should keep away from the

smart access system with push-button start antennas. (

P. 135)

The radio waves may affect the operation of such devices. If necessary, the entry

function can be disabled. Ask your Lexus dealer for details, such as the frequency of

radio waves and timing of the emitted radio waves. Then, consult your doctor 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 cardioverter defibril-

lators should consult the manufacturer of the device for information about its opera-

tion under the influence of radio waves.

Radio waves could have unexpected effects on the operation of such medical

devices.

Ask your Lexus dealer for details on disabling the entry function.

When adjusting the seat

●

Take care when adjusting the seat so that the head restraint does not touch the ceiling.

●

When folding down a rear seatback, if it interferes with a front seatback, adjust the front

seat position so that the seats no longer interfere with each other. However, if adjusting

WARNING

■

When adjusting the seat position

●

Take care when adjusting the seat position to ensure that other passengers 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.

●

Make sure to leave enough space around the feet so they do not get 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.
