an obstacle

A buzzer sounds when the sensors are
operating.



The buzzer beeps faster as the vehi-
cle approaches an obstacle. When
the vehicle comes within the follow-
ing distance of the obstacle, the
buzzer sounds continuously:

• Front center sensors: Approximately 1.3

ft. (40 cm)

• Except front center sensor: Approxi-

mately 1.1 ft. (35 cm)



When 2 or more obstacles are
detected simultaneously, the buzzer
system responds to the nearest
obstacle. If one or both come within
the above distances, the beep will
repeat a long tone, followed by fast
beeps.

WARNING

■

Cautions regarding the use of the

function

The driver is solely responsible for safe

driving. Always drive safely, taking care

to observe your surroundings.
The BSM function is a supplementary

function which alerts the driver that a

vehicle is in a blind spot of the outside

rear view mirrors or is approaching rap-

idly from behind into a blind spot. Do not

overly rely on the BSM function. As the

function cannot judge if it is safe to

change lanes, over reliance could lead to

an accident resulting in death or serious

injury.
As the system may not function correctly

under certain conditions, the driver’s

own visual confirmation of safety is nec-

essary.
