4-5. Using the driving support systems
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 is a supplementary system which alerts the driver that a
vehicle is present in the blind spot. Do not overly rely on the Blind Spot Monitor
system. The system cannot judge if it is safe to change lanes, therefore over reli-
ance 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.
■Handling the radar sensor
One Blind Spot Monitor sensor is installed inside the left and right side of the vehi-
cle rear bumper respectively. Observe the following to ensure the Blind Spot
Monitor system can function correctly.
●Do not subject the sensor or surrounding area on the bumper to a strong impact.
If the sensor moves even slightly off position, the system may malfunction and
vehicles that enter the detection area may not be detected. If the sensor or sur-
rounding area is subject to a strong im pact, always have the area inspected by
your Lexus dealer.
●Do not disassemble the sensor.
●Do not attach accessories or stickers to the sensor or surrounding area on the
bumper.
●Do not modify the sensor or surrounding area on the bumper.
●Do not paint the sensor or surrounding area on the bumper.
●Keep the sensor and its surrounding area
on the bumper clean at all times.
