WARNING

■

Handling the radar sensor
One Blind Spot Monitor sensor is installed inside the left and right side of
the vehicle rear bumper respectively. Observe the following to ensure the
Blind Spot Monitor can function correctly.

If the warning message does not disappear, have the vehicle inspected
by your Toyota dealer.

●

Do not subject a sensor or its surrounding area on the rear bumper to a
strong impact.
If a sensor is moved even slightly off position, the system may malfunction
and vehicles may not be detected correctly.
In the following situations, have your vehicle inspected by your Toyota
dealer.
• A sensor or its surrounding area is subject to a strong impact.
• If the surrounding area of a sensor is scratched or dented, or part of

them has become disconnected.

●

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 rear bumper any color other than an official Toyota color.

●

Keep the sensor and its surrounding
area on the bumper clean at all times.
If a sensor or its surrounding area on
the rear bumper is dirty or covered
with snow, the Blind Spot Monitor may
not operate and a warning message
(

→P. 255) will be displayed.

In this situation, clear off the dirt or
snow and drive the vehicle with the
operation conditions of the BSM func-
tion (

→P. 260) satisfied for approxi-

mately 10 minutes.

4-5. Using the driving support systems

The BSM function uses radar sensors to detect the following vehicles
traveling in adjacent lanes and advises the driver of the presence of
such vehicles via the indicators on the outside rear view mirrors.

Vehicles that are traveling in areas that are not visible using the out-
side rear view mirrors (the blind spots)
Vehicles that are approaching rapidly from behind in areas that are
not visible using the outside rear view mirrors (the blind spots)

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.
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.

Differences between the screen and the actual road
The distance guide lines and the vehicle width guide lines may not
actually be parallel with the dividing lines of the parking space, even
when they appear to be so. Be sure to check visually.
The distances between the vehicle width guide lines and the left
and right dividing lines of the parking space may not be equal, even
when they appear to be so. Be sure to check visually.
The distance guide lines give a distance guide for flat road sur-
faces. In any of the following situations, there is a margin of error
between the fixed guide lines on the screen and the actual dis-
tance/course on the road.
