How can the customer be made aware that a
radar unit is damaged?
If a radar unit has been damaged, the i-ACTIVSENSE
warning light turns on, a part of the i-ACTIVSENSE does
not operate, and a message indicating the damaged
radar unit is displayed.
Is there a recording function for the operation
history? Additionally, can verification of the
operation history at a dealer be done using a
diagnostic tester?
The operation log/history is not stored. A means of
storing the conditions at the time of a malfunction is
being investigated.
HMI
Question Answer
Is there a recording function for the
operation history? Additionally, can
verification of the operation history
at a dealer be done using a
diagnostic tester?
The operation log/history is not stored. A means of storing the
conditions at the time of a malfunction is being investigated. A
message indicating the reason for canceling the operation is
displayed in the instrument cluster. The message displays the nonoperation status and the cause mutually at intervals of 5 seconds.
Because the operation history
recorded in the vehicle cannot be
verified at a dealer, what questions
should the customer be asked for a
diagnosis?
The message that is displayed in the instrument cluster, where it
occurred, and when it occurred are important questions to ask the
customer.
With the 6th generation, a DTC is
stored when the FSC is temporarily
stopped. Is this function available on
the 7th generation?
The function is not available.
For the systems related to hazard
avoidance, are they restored after
switching the ignition ON/OFF?
The systems related to hazard avoidance are restored after the
ignition is switched ON, even if the ignition was switched OFF,
however, the related warning message remains the same as
before the ignition was switched OFF.

conditions?
DAA: Aims for a timing when the vehicle speed is 40 mph (65 km/h) or more. The
system performs learning over a traveled distance applicable to this condition.
DM: Aims for a timing when the vehicle speed is about 3 mph (5 km/h) or more.
Does the
DM/DAA

mask is worn,
and with that, is
there a limit to
the type of mask
and color?
The owner’s manual indicates the following: The system may not operate normally
under the following conditions: When wearing glasses or sunglasses.
The description indicates that the system may operate, however, with regard to this
matter, it is based on the assumption of a general mask (white, square-shape).

360°VM
Question Answer
How far has the 360° degree view
monitor camera performance
improved from the 6th generation
to 7th generation vehicles?
6th generation: Video signal is analog/camera with 300,000 pixel.
7th generation: Video signal is digital/camera with 1,300,000 pixel.
The camera image is difficult to
view or it sometimes flickers. What
could be the cause of this?
The following are possible causes:
1. Flares/ghosts/halation: Highly bright light is picked up by the
camera or there is oil on the lens.
2. LED flicker: Flicker from the LED of own vehicle or other vehicles
may occur.
3. Noise: Noise which occurs during low light conditions such as at
night.
4. Other: Rain or snow on the lens, backlight.
If the tires are replaced, is camera
aiming required?
If tire replacement is required, such as changing to winter tires,
there is the possibility of the camera images deviating, therefore
aiming may be necessary. Do an inspection using the inspection
procedure and then do the aiming if necessary.
NOTE: For tire sizes other than the factory setting, it would not be
covered by the warranty.
SBS
Question Answer
Are there any differences in the functions of the
SCBS (low speed) on the 6th generation and the
SBS?
The AEB (automatic braking) function when driving in
the forward direction was standardized on the SBS.

addition to the torque control.
For inquiries concerning unintended
SBS operation, does the operation
