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

Observe the following precautions.

Failure to do so may cause parts of the

body to be caught, resulting in serious

injury.

●

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.

■

Power trunk opener and closer

Observe the following precautions when

operating the power trunk opener and

closer.

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.

●

On an incline, the trunk lid may sud-

denly shut after it opens automatically.

Make sure the trunk lid is fully open

and secure before using the trunk.

●

In the following situations, the power

trunk opener and closer may detect an

abnormality and automatic operation

may be stopped. In this case, the trunk

lid has to be operated manually. Take

extra care in this situation, as the

stopped trunk lid may suddenly shut,

causing an accident.

lid. The power trunk opener and closer

may not operate, causing itself to mal-

function, or the trunk lid may suddenly

shut again after it is opened.

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

hybrid system 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

60 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.

●

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 follow-

ing 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.118)

●

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 6 ft. (2 m)

of the vehicle.

●

The smart access system with push-but-

ton start can be deactivated in advance.

●

Setting the electronic key to battery-sav-

ing mode helps to reduce key battery

depletion. (

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.)
