7-21. Driver Monitoring Sys-
tem (if equipped)
.
In some circumstances, the sys-
tem may not be able to correctly
detect the driver state.
Driver Monitoring System is introduced as
DriverFocus in some countries.
The Driver Monitoring System monitors
possible cases when the driver is not
paying attention to the forward direction,
and also recognizes individual users.
This system warns the driver of inattentive/
drowsy driving, and can support safe and
comfortable driving by automatically re-
trieving the following settings.
NOTE
.
The user recognition camera does
not save images, audio, or video.
The Driver Monitoring System may
not operate correctly when sunlight
is shining into the vehicle in the
following ways.
.

Camera
– Sunlight is shining directly (or
through glass) onto the user
recognition camera.
– There are shadows on the dri-
ver’s face caused by sunlight (or
any light with a strong infrared
component).
– There are large momentary fluc-
tuations in the strength of the
sunlight (or any light with a
strong infrared component) shin-
ing on the face.

When a user is registered, various settings
are automatically retrieved when the user
enters the vehicle.
The interior temperature setting can also
be changed using gesture control. Refer to
“Gesture control” �P391.

Overconfidence because you
are driving a vehicle with the
Driver Monitoring System
could easily lead to a serious
accident.

This system cannot detect if the
driver is feeling drowsy or is
concentrating on safe driving.
.
Correct detection may not be possi-
ble when a device that includes an
infrared light source (such as a
commercially available driver mon-
itoring system) is installed in the
vehicle interior.
It cannot judge if the driver is
awake or asleep, if their driving
abilities have diminished, or if
they are concentrating on safe

.
The Driver Monitoring System may
not operate correctly at the following
times when the driver is wearing
glasses or sunglasses.
– The sunglasses do not allow the
easy passage of infrared light.
– The surrounding scenery is re-
flected strongly in the lenses of
the glasses or sunglasses.
– The eyes are hidden by the frame
of the glasses and the user
recognition camera cannot de-
tect the eyes.
– The light from an infrared light
source (LED) is reflected in the
lenses of the glasses or sun-
glasses.

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
.
.
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.

– The driver is wearing an eye-
patch.
– The driver is wearing a hat set
deeply over the eyes.
.
.
Depending on the type of mask,
correct detection of inattentive/
drowsy driving may not be possible.
Correct user recognition is not pos-
sible if the eyes, nose, or mouth is
covered with a mask, muffler, sun-
glasses, or other item.
The Driver Monitoring System may
not operate correctly when the eye-
brows, eyes, nose, or mouth is

sound.
.
.
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
.
.
The inattentive driving warning buz-
zer may sound if the driver leans
forward or puts his or her head out of
the window while driving.
The inattentive driving warning buz-
zer will not sound when the vehicle
is stopped or travelling at slow
speed even if the driver is not
looking ahead.
The Driver Monitoring System col-
lects and stores data regarding
drivers’ facial features. Facial recog-
nition data is stored locally and does
not leave the vehicle. It is not
transmitted to or stored by SUBARU
or anyone else. The Driver Monitor-
ing System may be disabled and any
stored driver data may be deleted by
following the instructions below. If
the Driver Monitoring System is
disabled, it will be unable to provide
any of its safety or convenience
functions.

& Gesture control
CAUTION
Gesture control is a function that allows
you to raise or lower the set temperature
on the driver’s side by 4 steps of the
temperature dial when a specific gesture
operation is performed in the area imme-
diately in front of the navigation system
and/or audio system.
Gesture control allows you to operate the
climate control system without taking your
eyes off the road and reduces the time you
take your hand off the steering wheel.
Wait until the seat automatic retrac-
tion is fully completed before sitting
in the driver’s seat.
NOTE
.
If the seat position is not registered
in the access key fob memory, the
automatically retract seat on entry
function can be used.
Even when the automatically retract
seat on entry setting is ON, the
automatically retract seat on entry
function automatically turns OFF
when the user recognition function
is OFF.
Automatically retract seat on entry
cannot be selected when the Driver
Monitoring System OFF indicator,
Driver Monitoring System temporary
stop indicator, or Driver Monitoring
System warning is illuminated.
This function will operate if the seat
is in front of the center of the seat
sliding mechanism.

Gesture control can be used under the
following conditions:
.
.
The engine is running.
The climate control system is activated.
