3-1.Key information

The following keys are provided with 
the vehicle.

Electronic keys

• Operating the smart access system with 

push-button start (

■

When riding in an aircraft

When bringing an electronic key onto an 

aircraft, make sure you do not press any 

buttons on the electronic key while inside 

the aircraft cabin. If you are carrying an 

electronic key in your bag, etc., ensure that 

the buttons are not likely to be pressed acci-

dentally. Pressing a button may cause the 

electronic key to emit radio waves that 

could interfere with the operation of the air-

craft.

■

Electronic key battery depletion

●

The standard battery life is 1 to 2 years.

●

If the battery becomes low, an alarm will 

sound in the cabin when the hybrid sys-

tem is stopped.

●

To reduce key battery depletion when the 

electronic key is to not be used for long 

periods of time, set the electronic key to 

the battery-saving mode. (



P.126)

●

As the electronic key always receives 

radio waves, the battery will become 

depleted even if the electronic key is not 

used. The following symptoms indicate 

that the electronic key battery may be 

depleted. Replace the battery when nec-

essary.

• The smart access system with push-but-

ton start or the wireless remote control 

does not operate.

• The detection area becomes smaller.

• The LED indicator on the key surface 

does not turn on.

●

To avoid serious deterioration, do not 

leave the electronic key within 3 ft. (1 m) 

of the following electrical appliances that 

produce a magnetic field:

• TVs

• Personal computers

• Cellular phones, cordless phones and 

battery chargers

• Recharging cellular phones or cordless 

phones

• Table  lamps

• Induction cookers

■

■

Confirmation of the registered key 

number

The number of keys already registered to 

the vehicle can be confirmed. Ask your 

Lexus dealer for details.

■

If “A New Key has been Registered 

Contact Your Dealer for Details” is 

shown on the multi-information display

This message will be displayed each time 

the driver’s door is opened when the doors 

are unlocked from the outside for approxi-

mately one week after a new electronic key 

has been registered.

If this message is displayed but you have not 

had a new electronic key registered, ask 

your Lexus dealer to check if an unknown 

electronic key (other than those in your 

possession) has been registered.

NOTICE

■

To prevent key damage

●

Do not drop the keys, subject them to 

strong shocks or bend them.

●

Do not expose the keys to high tem-

peratures for long periods of time.

●

Do not get the keys wet or wash them 

in an ultrasonic washer, etc.

●

Do not attach metallic or magnetic 

materials to the keys or place the keys 

close to such materials.

●

Do not disassemble the keys.

●

Do not attach a sticker or anything else 

to the surface of the electronic key.

●

Do not place the keys near objects that 

produce magnetic fields, such as TVs, 

audio systems and induction cookers, 

or medical electrical equipment, such 

as low-frequency therapy equipment.

■

Carrying the electronic key on your 

person

Carry the electronic key 3.9 in. (10 cm) 

or more away from electric appliances 

that are turned on. Radio waves emitted 

from electric appliances within 3.9 in. (10 

cm) of the electronic key may interfere 

with the key, causing the key to not func-

tion properly.

incline, whether there is enough space 

for a door to open and whether a strong 

wind is blowing. When opening or clos-

ing the door, hold the door handle tightly 

to prepare for any unpredictable move-

ment.

Power back door

The power back door can be 
opened using the power back door 
opener switch, smart access system 
with push-button start or wireless 
remote control.

WARNING

Observe the following precautions.

Failure to do so may result in death or 

serious injury.

■

Before driving the vehicle

Before driving the vehicle, make sure 

that the power back door is fully closed. If 

the power back door is not fully closed, it 

may open unexpectedly while driving, 

causing an accident.

■

Caution while driving

●

Keep the power back door closed 

while driving.

If the power back door is left open, it may 

hit nearby objects while driving or lug-

gage may be unexpectedly thrown out, 

causing an accident.
In addition, exhaust gases may enter the 

vehicle, causing death or a serious health 

hazard. Make sure to close the power 

back door before driving.

●

Never let anyone sit in the luggage 

compartment. In the event of sudden 

braking, sudden swerving or a colli-

sion, they are susceptible to death or 

serious injury.

■

When children are in the vehicle

Observe the following precautions.

Failure to do so may result in death or 

serious injury.

●

Do not allow children to play in the lug-

gage compartment.

If a child is accidentally locked in the lug-

gage compartment, they could have heat 

exhaustion or other injuries.

●

Do not allow a child to open or close 

the power back door.

Doing so may cause the power back 

door to move unexpectedly, or cause the 

child’s hands, arms, head, or neck to be 

caught by the closing power back door.

■

Operating the power back door

Observe the following precautions.

Failure to do so may cause parts of the 

body to be caught, resulting in death or 

serious injury.

●

Remove any heavy loads, such as snow 

and ice, from the power back door 

before opening it. Failure to do so may 

cause the power back door to sud-

denly shut again after it is opened.

●

When opening or closing the power 

back door, thoroughly check to make 

sure the surrounding area is safe.

●

If anyone is in the vicinity, make sure 

they are safe and let them know that 

the power back door is about to open 

or close.

●

Use caution when opening or closing 

the power back door in windy weather 

as it may move abruptly in strong wind.

●

The power back door may suddenly 

shut if it is not opened fully. It is more 

difficult to open or close the back door 

on an incline than on a level surface, so 

beware of the back door unexpectedly 

opening or closing by itself. Make sure 

that the back door is fully open and 

secure before using the luggage com-

partment.

●

When closing the power back door, 

take extra care to prevent your fingers, 

etc., from being caught.

●

When closing the power back door, 

make sure to press it lightly on its outer 

surface. If the back door handle is used 

to fully close the power back door, it 

may result in hands or arms being 

caught.

●

Do not pull on the back door spindle 

(



P.122) to close the power back 

door, and do not hang on the back 

door spindle.

Doing so may cause hands to be caught 

or the back door spindle to break, caus-

ing an accident.

●

If a bicycle carrier or similar heavy 

object is attached to the power back 

door, it may suddenly shut again after 

being opened, causing someone’s 

hands, arms, head or neck to be 

caught and injured. When installing an 

accessory part to the power back 

door, using a genuine Lexus part is 

recommended.
