Battery-saving function

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

tery and the 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 in an area of 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.

●

If the smart access system with push-button start has not been used for 14 days or lon-

ger, the doors cannot be unlocked at any doors except the driver’s door. In this case,

take hold of the driver’s door handle, or use the wireless remote control or the mechan-

ical key, to unlock the doors.

■

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.

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. 550)

●

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

objects
• Portable radio, cellular phone, cordless phone or other wireless communication

device

• 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

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.

●

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

●

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 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 on the instrument panel, luggage cover (if equipped) 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 60 seconds if the doors

are not opened and closed.)

●

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

unlock operation.

●

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.)

●

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 electronic key to battery-saving mode to disable the smart access system with

push-button start. (

P. 140)

142

●

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.

●

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 or back door unlock switch is

pressed.

●

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.

■

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 access system with push-button start can be deactivated in advance.

(

P. 584)

■

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.)

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 antennas. (



P. 138)

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.

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.

■

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.
