inspected by any authorized Lexus dealer or repairer, or another duly quali-
fied and equipped professional.

The Blind Spot Monitor function uses radar sensors to detect vehicles that
are traveling in an adjacent lane in the area that is not reflected in the out-
side rear view mirror (the blind spot), and advises the driver of the vehi-
cles existence via the outside rear view mirror indicator.
The areas that vehicles can be detected in are outlined below.
The range of the detection area
extends to:
Approximately 3.5 m (11.5 ft.)
from the side of the vehicle
The first 0.5 m (1.6 ft.) from the side
of the vehicle is not in the detection
area
Approximately 3 m (9.8 ft.) from

CAUTION
Cautions regarding the use of the system
The driver is solely responsible for safe driving. Always drive safely, taking
care to observe your surroundings.
The Blind Spot Monitor function is a supplementary function which alerts the
driver that a vehicle is present in the blind spot. Do not overly rely on the Blind
Spot Monitor function. The function cannot judge if it is safe to change lanes,
therefore over reliance could cause an accident resulting in death or serious
injury.
According to conditions, the system may not function correctly. Therefore the
driver’s own visual confirmation of safety is necessary.
