WARNING

Observe the following precautions.

Failure to do so may result in death or 

serious injury.

■

Before driving

●

Make sure that the trunk lid is fully 

closed. If the trunk lid is not fully 

closed, it may open unexpectedly 

while driving and hit near-by objects or 

luggage in the trunk may be thrown 

out, causing an accident.

●

Do not allow children to play in the 

trunk.

If a child is accidentally locked in the 

trunk, they could suffer from heat 

exhaustion, suffocation or other inju-

ries.

●

Do not allow a child to open or close 

the trunk lid.

Doing so may cause the trunk lid to 

open unexpectedly, or cause the 

child’s hands, head, or neck to be 

caught by the closing trunk lid.

■

Important points while driving

Never let anyone sit in the trunk. In the 

event of sudden braking or a collision, 

they are susceptible to death or serious 

injury.

■

Using the trunk

3-2. Opening, closing and locking the doors and trunk

WARNING

●

Remove any heavy loads, such as snow 

and ice, from the trunk lid before 

opening it. Failure to do so may cause 

the trunk lid to suddenly shut again 

after it is opened.

●

When opening or closing the trunk lid, 

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 trunk is about to open or close.

●

Use caution when opening or closing 

the trunk lid in windy weather as it may 

move abruptly in strong wind.

●

The trunk lid may suddenly shut if it is 

not opened fully. It is more difficult to 

open or close the trunk lid on an 

incline than on a level surface, so 

beware of the trunk lid unexpectedly 

opening or closing by itself. Make sure 

that the trunk lid is fully open and 

secure before using the trunk.

●

When closing the trunk lid, take extra 

care to prevent your fingers etc. from 

being caught.

●

When closing the trunk lid, make sure 

to press it lightly on its outer surface. If 

the trunk handle is used to fully close 

the trunk lid, it may result in hands or 

arms being caught.

●

Do not attach any accessories other 

than genuine Lexus parts to the trunk 

lid. Such additional weight on the trunk 

lid may cause the lid to suddenly shut 

again after it is opened.

■

Trunk easy closer

In the event that the trunk lid is left slightly 

open, the trunk easy closer will automati-

cally close it to the fully closed position. It 

takes several seconds before the trunk 

easy closer begins to operate. Be careful 

not to catch fingers or anything else in 

the trunk lid, as this may cause bone frac-

tures or other serious injuries.

■

Power trunk lid

Observe the following precautions when 

operating the power trunk lid.

Failure to do so may cause serious injury.

●

Check the safety of the surrounding 

area to make sure there are no obsta-

cles or anything that could cause any 

of your belongings to get caught.

●

If anyone is in the vicinity, make sure 

they are safe and let them know that 

the trunk is about to open or close.

●

If the trunk closer switch is pressed 

while the trunk lid is opening during 

automatic operation, the trunk lid 

stops opening. Take extra care when 

on an incline, as the trunk lid may open 

or close suddenly.

lid. The power trunk lid may not oper-

ate, causing itself to malfunction, or the 

trunk lid may suddenly shut again after 

it is opened.

■

Hands Free Power Trunk Lid (if 

equipped)

Observe the following precautions.

Failure to do so may cause serious injury.

●

Exhaust gasses cause the exhaust 

pipes to become quite hot. When 

operating the Hands Free Power Trunk 

Lid, be careful not to touch the exhaust 

pipe.

●

Do not operate the Hands Free Power 

Trunk Lid if there is little space under 

the rear bumper.

■

Jam protection function

Observe the following precautions.

Failure to do so may cause serious injury.

●

Never use any part of your body to 

intentionally activate the jam protec-

tion function.

●

The jam protection function may not 

work if something gets caught just 

before the trunk lid fully closes. Be 

careful not to catch fingers or anything 

else in the trunk lid.

●

The jam protection function may not 

work depending on the shape of the 

object that is caught. Be careful not to 

catch fingers or anything else.

Make sure that there is no luggage or 

snow on the trunk lid before operating 

the power trunk lid. In addition, make 

sure that there is no ice between the 

trunk lid and frame that prevents 

movement of the trunk lid. Operating 

the power trunk lid when excessive

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 center 

of the rear bumper 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 

117

3-2. Opening, closing and locking the doors and trunk

Be

 driving

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 auto-

matically 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.

●

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 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.116)

●

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.

■

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. (

P.116)

■

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 operating the system from the out-

side 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 pre-
vention function may not operate.)

●

Do not leave the electronic key inside the 

trunk.

The key confinement prevention function 

may not operate, depending on the loca-

tion of the key (the inside edge of the 

118

trunk), conditions (inside a metal bag, 

close to metallic objects) and the radio

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.114)

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.

Ask any authorized Lexus retailer or 

Lexus authorized repairer, or any reliable 

repairer for details on disabling the entry 

function.

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.

●

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.

■

Operating the front passenger’s seat 

from the driver’s seat or rear seat

Do not operate the front passenger’s seat 

when a passenger is seated in it. In addi-

tion, do not let anyone sit down in the 

front passenger’s seat while the seat is 

being operated or when the head 

restraint is being folded. The front pas-

senger may catch their legs between the 

instrument panel and seat, or the head 

restraint may interfere with their head, 

resulting in injury.

■

When the front passenger’s seat is 

folded forward

If the outside rear view mirror is difficult 

to see, due to the position of the front 

passenger’s seat, move the front passen-

ger’s seat to an appropriate position.

Doing so may lead to mishandling of the 

vehicle and cause an accident, resulting 

in death or serious injury.

NOTICE

■

Operating the front passenger’s seat 

from the driver’s seat or rear seat

Before operating the front passenger’s 

seat, make sure that there is no luggage 

or any other objects on the seat or in the 

footwell that could prevent its operation.

Such items may result in excess force 

being applied, causing damage to the 

seat and/or the luggage.
