SEA (Safe Exit Assist)

System components

: If equipped

The Safe Exit Assist is a

system that uses radar sen-

sors installed on the inner

side of the rear bumper to

help occupants judge if an

approaching vehicle or

bicycle may collide with a

door to reduce the possibil-

ity of a collision.

Multi-information display

Turning the Safe Exit Assist on/off

When the system determines that

the possibility of a collision with a

door is high, the target door is dis-

played on the multi-information dis-

play. Also, if the door is opened

when the outside rear view mirror

indicator is illuminated, a buzzer

will sound as a warning.

WARNING

■Cautions regarding the use of

the system

●The driver is solely responsible

for safe driving. Always drive

safely, taking care to observe

your surroundings.

●Safe Exit Assist is a supplemen-

tary system that, when the vehi-

cle is stopped, informs

Outside rear view mirror indi-

cators

occupants of the existence of

approaching vehicles and bicy-

cles. As this system alone can-

not be used to judge safety,

over-reliance on this system

may lead to an accident result-

ing in death or serious injury.

As the system may not function

correctly under certain condi-

tions, visual confirmation of

safety with the passengers’ own

eyes and mirrors is necessary.

When a vehicle or bicycle which

may collide with a door (other than

the back door) when opened is

detected, the outside rear view mir-

ror indicator on the detected side

will illuminate. If the door on the

detected side is open, the outside

rear view mirror indicator will blink.

■Outside rear view mirror indica-

tor visibility

In strong sunlight, the outside rear

view mirror indicator may be difficult

to see.

■Buzzer

If the volume setting of the audio

system is high or the surrounding

area is loud, it may be difficult to

hear the buzzer.
