178NOTEEven when the operation conditions of
the high beam assist function are met,
there may be a case in which the high
beam assist indicator does not illumi-
nate.▼ How to temporarily lower the sensi -
tivity of the high beam assist func -
tion
The sensitivity of the high beam assist
function can be lowered by using the
following operations.
1. After turning the ignition switch to the
“ON” position, set the light control switch
to the “AUTO” position and push the
signal lever forward (high beam position).
2. After the high beam assist indicator on
the combination meter will illuminate, turn
the ignition switch to the “OFF” position.
3. Turn the ignition switch to the “ON”
position and within approximately 15
seconds, press the “ ” (following
distance setting) switch more than 10
times consecutively.
When the sensitivity of the high beam
assist function is lowered, the high beam
assist indicator light “ ” on the combina-
tion meter display (col or TFT) will flash.
NOTEThe sensitivity of the high beam
assist function cannot be lowered in
the following conditions. - Cruise control or Adaptive
Cruise Control indicator is illumi-
nated.
- The EyeSight warning indicator
(yellow) is illuminated
 The sensitivity of the high beam
assist function retu rns to normal level
the next time the ignition switch is
turned to the “OFF ” position and the
engine is restarted.
▼ How to change the headlight mode
manually
Change to the low beam:
 Set the light control switch to “ ”.
 Pull the lever while the high beam is
turning on and release it.
Change to the high beam:
Push the lever forward and release it.
At this time, the high beam assist function
will turn off, the high beam assist indicator
will turn off and the high beam indicator
light will turn on.NOTE After manually changing the head-
light mode to the high beam, if you turn on the high beam assist function, push

the lever forward and release it.
 When manually changing the head-
light mode to the high beam, if you turn
the light control switch to the “ ”
position, the parking lights, side
marker lights, tail lights and license
plate lights will turn on.
▼ Tips for the high beam assist
system
The high beam assist function recog-
nizes the condition surrounding the
vehicle based on the brightness of illumi-
nation ahead of your vehicle, etc. There-
fore, the headlight mode may switch in
some situations that do not match to the
driver’s sense.
 A bicycle or cargo cycle may not be
detected.
 Under the following situations, the
brightness of ambient illumination may not
be detected correctly and the high beam
assist function may not work properly. As
a result, the glare of the high beam may
disturb the oncoming vehicle or vehicle
ahead. Also, the low beam mode may
continue although there are no oncoming
vehicles and vehicles ahead. In the such
cases, change the headlight mode manu-
ally.

vehicle or the tail lights of a vehicle
ahead are dirty or discolored, or if the
light beams are not aimed correctly.
- When a rapid change of brightness
continues while driving.
- When driving on a road with many
ups and downs or uneven surfaces.
- When driving on a road with many
curves.
- When there are some objects that

oncoming vehicle suddenly in a blind
curve.
- When another vehicle passes in
front of your vehicle.
- When an oncoming vehicle or
vehicle ahead comes in and out of view
because of continuous curves, median

 If the stereo camera detects the light of
the front fog lights of an oncoming vehicle,
the headlight mode may change from the

BSD/RCTA (If Equipped)
272It is mounted on each side of the outside
mirrors.
The indicator light will illuminate
when a
vehicle approaching from behind is
detected.
The indicator light will flash
to warn the
driver of dangers under the following
conditions.
 While the indicator light is illuminating,
if the turn signal lever is operated toward
the side in which this light turned on
 When reversing the vehicle while the
system detects a vehicle approaching
from either side
▽ BSD/RCTA approach indicator
light dimming function
When the headlights are turned on, the
brightness of the BSD/RCTA approach
indicator light will be reduced.
NOTE You may have difficulty seeing the
BSD/RCTA approach indicator light
under the following conditions. - When sunlight shines directly on
it
- When the headlight beams from
a vehicle traveling behind shines
directly on it
 While the illumination brightness
control dial is in the fully upward posi- tion, even if the headlights are turned

on, the brightness of the BSD/RCTA
approach indicator light will not be
reduced. For details about the illumina-
tion brightness control dial, refer to
"Illumination Brightness Control"
 P130.
▼ BSD/RCTA approach warning
buzzer (only when reversing)
A warning buzzer sounds along with
flashing of the BSD/RCTA approach indi-
cator light to warn the driver of dangers.
The setting of the warning buzzer volume
can be changed by operating the center
information display. For details, refer to
"Car settings"  P165.
▼ Safety tips regarding the BSD/
RCTA approach indicator light/
warning buzzer
 In the following cases, operation of the
BSD/RCTA approach indicator light and
the warning buzzer may be delayed or the
system may fail to issue these warnings.
- When a vehicle moves to the neigh-
boring lane from a lane next to the
neighboring lane
- When driving on a steep incline or
on repeated sharp uphill and downhill
grades
- When going beyond a pass - When both your vehicle and a

vehicle driving on a neighboring lane
are driving on the far side of each lane.
- When several narrowly-spaced
vehicles are approaching in a row
- In low radius bends (tight bends or
when making turns at an intersection)
- When there is a difference in height
between your lane and the neighboring
lane
- Immediately after the BSD/RCTA is
activated by touching “BSD/RCTA”
- Immediately after the shift lever/
select lever is shifted to the “R” position
- When extremely heavy cargo is
loaded in the trunk
 During reversing, operation of the BSD/
RCTA approach indicator light and the
warning buzzer may be delayed or the
system may fail to issue these warnings
under the following conditions.
- When backing out of an angled
parking space
- When a large-sized vehicle is
parked next to your vehicle (That
vehicle prevents the propagation of
radar waves.)
- When reversing on sloped roads
- When reversing at a high speedBRZ_U.book 272 ページ ２０２２年３月２９日　火曜日　午後３時５９分
