Driver Monitoring System
the face and the system.
. If a thick cover is attached to the
steering wheel, then depending on
the position set for the tilt/telescopic
steering wheel, the cover may block
the system's view of the face, and
the system and the Driver Monitor-
ing System may not operate cor-
rectly.
. Do not attach any stickers to the
user recognition camera or the infra-
red light source (LED). If the user
recognition camera or infrared light
source (LED) is covered by an
obstruction, it will not be possible
to correctly monitor the driver.
. If an accessory is hung from the
inside mirror, correct detection may
not be possible.
. Do not touch the user recognition
camera or the infrared light source
(LED) directly with your fingers. If
there is dirt or a fingerprint on these
parts, it will not be possible to
correctly monitor the driver. If there
is dirt or a fingerprint on these parts,
either wipe them with a soft dry
cloth, or wipe gently with a damp
cloth after first firmly wringing the
water out.
. If the surface of the user recognition
camera or the infrared light source
(LED) becomes scratched, correct
detection may not be possible. Be
careful that hard objects do not
contact these parts.
. If there is condensation on the user
recognition camera or the infrared
light source (LED), correct detection
may not be possible. If there is
condensation on these parts, wipe
it away with a soft dry cloth.
. When registering a user for user
recognition, avoid closing your eyes
as much as possible.
. If the user recognition success rate
is low, it is possible that the user is
not correctly registered. Delete the
registered data and perform regis-
tration again.
. If a user frequently drives both with
glasses and contact lenses, it is
recommended that registration be
performed both when wearing
glasses and when wearing contact
lenses.
. User recognition starts immediately
after entering the vehicle, however if
the user looks downward or at the
driver side mirror for a long time, the
user may not be recognized.
. When one person among twins or
another pair of persons with similar
facial features is registered, the
other person may be incorrectly
recognized as the registered user
when entering the vehicle.
. If the person in the passenger's seat
leans into the driver's seat, or in
other cases when there are two or
more faces near the driver's seat, the
system may not operate correctly.
. There are cases when the system
concludes that the user's eyes are
closed when the user is looking
downward during driving, such as
when checking instruments or the
navigation screen. In such cases,
the drowsy driving warning buzzer
may sound or the system may
otherwise not operate correctly.
. If the eyes are narrowed when laugh-
ing or when there is a dazzling
outside light, the system may judge
that the eyes are closed and the
drowsy driving warning buzzer may
sound or the system may otherwise
not operate correctly.
. The drowsy driving or asleep warn-
ing states are recognized from the
length of time and percentage of
time that the eyes are closed. The
drowsy driving warning buzzer will
not sound simply when the driver
feels sleepy or yawns.
. Even when the driver does not feel
sleepy, if his or her eyes are closed
or if he or she blinks frequently, the
drowsy driving warning buzzer may
