2023 TOYOTA COROLLA HATCHBACK warning

2054-5. Using the driving support systems
4
Driving
Through control state “warning
phase 1” and “warning phase 2”,
the system determines if the
driver is aware and responsive
while outputting a warning and
controlling the vehicle speed. If
the system determines the
driver is not responsive, it will
operate in control state “deceler-
ation stop phase” and “stop hold
phase” and decelerate and stop
the vehicle. It will then operate
continuously in “stop hold
phase”.
■Operating conditions
This system opera tes when all of
the following cond itions are met:
●When the LTA is on
●When the vehicle speed is
approximately 30 mph (50 km/h)
or more
■Operation cancelation condi-
tions
In the following si tuations, system
operation will be canceled:
●When LTA control has been can-
celed (the LTA switch has been
pressed, etc.)
●When the dynamic radar cruise
control has been canceled
●When driver operations are
detected (the steering wheel is
held, the brake pedal, accelerator
pedal, parking brake, hazard light
switch, or turn sig nal lever is oper-
ated)
●When the driving assist switch is
pressed while in the stop and hold
phase
●When the engine switch has been
turned from ON to off
●Situations in whic h some or all of
the functions of the system cannot operate:
P. 1 6 6
■LTA control when operation is
canceled
When emergency driving stop sys-
tem operation is canceled, LTA con-
trol may also be canceled.
If driving operations are not
detected after the hands off
steering wheel warning oper-
ates, a buzzer will sound inter-
mittently and a message will be
displayed to warn the driver, and
the system will judge if the driver
is responsive or not. If driving
operations, such as holding the
steering wheel, are not per-
formed within a certain amount
of time, the system will enter
warning phase 2.
After entering warning phase 2,
a buzzer will sound in short
intervals and a message will be
displayed to warn the driver, and
the vehicle will slowly deceler-
ate. If driving operations, such
as holding the steering wheel,
are not performed within a cer-
tain amount of time, the system
will determine that the driver is
not responsive and enter the
deceleration stop phase.
The audio system will be muted
until the driver becomes respon-
sive.
When the vehicle is decelerating,

depending on the road conditions,
etc.
After entering the deceleration
stop phase, a buzzer will sound
continuously and a message will
be displayed to warn the driver,
and the vehicle will slowly decel-
erate and stop. After the vehicle
stops, the system will enter the
stop and hold phase.
After the vehicle is stopped, the
parking brake will be applied
automatically. After entering the
stop and hold phase, the buzzer
will continue sounding continu-
ously and the emergency flash-
ers (hazard lights) will flash to
warn other drivers of the emer-
gency.

RSA (Road Sign
Assist)*
The RSA system detects
specific road signs using
the front camera and/or nav-
igation system (when speed
limit information is avail-
able) and warns the driver
via displays and buzzers.
WARNING
■For safe use
●Driving safely is solely the
responsibility of the driver. Pay
careful attent ion to the sur-
rounding conditions in order to
ensure safe driving.
●Do not rely so lely upon the
RSA. The RSA assists the
driver by providing road sign
information, but it is not a
replacement for the driver’s own
vision and awareness. Driving
safely is solely the responsibility
of the driver. Pay careful atten-
tion to the surrounding condi-
tions in order to ensure safe
driving.
■Situations in which the RSA
should not be used
●When it is necessary to disable
the system: P.161
■Situations in which the sys-
tem may not ope rate properly
●Situations in which the sensors
may not operate properly:

detected for a certain distance
●When the system determines that
the road being driven on has
changed, such as after a left or
right turn
■Situations in which the display
function may not operate prop-
erly
In the following si tuations, the RSA
system may not operate properly
and may not detect signs or may
display the incorrect sign. However,
this does not indicate a malfunction.
●When a sign is dirty, faded, tilted
or bent
●When the contrast of an electronic
sign is low
●When all or part of a sign is hidden
by a tree, ut ility pole, etc.
●When a sign is detected by the
front camera for a short amount of
time
●When the driving state (turning,
changing lanes, etc.) is judged
incorrectly
●W h e n a s i g n i s i m m e d i a t e l y a f t e r a
freeway junction or in an adjacent
lane just before merging
●When stickers are attached to the
rear of a preceding vehicle
●When a sign similar to a system
compatible sign is detected as a
system compatible sign
●When a speed limit sign for a
frontage road is within detection
range of the front camera
●When driving around a round-
about
●When a sign inte nded for trucks,
etc. is detected
●When the navigation system map
data is out of date
●When the navigation system can-
not be used
In this case, the speed limit signs
displayed on the multi-information
display and navigation system dis-
play may differ.
In the following situations, the
RSA system will output a warn-
ing to notify the driver.
 If the vehicle speed exceeds
the speed warning threshold
of the speed limit sign dis-
played on the display, the sign
display will be emphasized
and a buzzer will sound.
 When the RSA system
detects a do not enter sign
and determines that the vehi-
cle has entered a no-entry
area, the do not enter sign
displayed on the display will
flash and a buzzer will sound.

BSM (Blind Spot Moni-
tor)*
The Blind Spot Monitor is a
system that uses rear side
radar sensors installed on
the inner side of the rear
bumper on the left and right
side to assist the driver in
confirming safety when
changing lanes.
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 is a sup-
plementary function which alerts
the driver that a vehicle is in a
blind spot of the outside rear
view mirrors or is approaching
rapidly from behind into a blind
spot. Do not overly rely on the
Blind Spot Monitor. As the func-
tion cannot judge if it is safe to
change lanes, over reliance
could lead to an accident result-
ing in death or serious injury. As
the system may not function
correctly under certain condi-
tions, the driver’s own visual
confirmation of safety is neces-
sary.

WARNING
■To ensure the system can
operate properly
Blind Spot Monitor sensors are
installed behind the left and right
sides of the rear bumper respec-
tively. Observe the following to
ensure the Blind Spot Monitor can
operate correctly.
●Keep the sensors and the sur-
rounding areas on the rear
bumper clean at all times.
If a sensor or its surrounding area
on the rear bumper is dirty or cov-
ered with snow, the Blind Spot
Monitor may not operate and a
warning message will be dis-
played. In this situation, clear off
the dirt or snow and drive the
vehicle with the operation condi-
tions of the BSM function
(  P.212) satisfied for approxi-
mately 10 minutes. If the warning
message does not disappear,
have the vehicle inspected by
your Toyota dealer.
●Do not attach accessories,
stickers (including transparent
stickers), aluminum tape, etc. to
a sensor or its surrounding area
on the rear bumper.
●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 si tuations, 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 sen- sor is scratched or dented, or
part of them h as become dis-
connected.
●Do not disassemble the sensor.
●Do not modify the sensor or sur-
rounding area on the rear
bumper.

intended to assist the driver
in checking areas that are
not easily visible when
backing up.
WARNING
■Cautions regarding the use of
the system
The driver is solely responsible for
safe driving. Always drive safely,
taking care to o bserve your sur-
roundings. The RCTA function is
only a supplementary function
which alerts the driver that a vehi-
cle is approaching from the right
or left at the rear of the vehicle. As
the RCTA function may not func-
tion correctly under certain condi-
tions, the driver’s own visual
confirmation of safety is neces-
sary. Over relia nce on this func-
tion may lead to an accident
resulting death or serious injury.

Safe Exit Assist*
The safe exit assist is a sys-
tem that uses rear side
radar sensors installed on
the inner side of the rear
bumper to help occupants
judge if an approaching
vehicle or bicycle may col-
lide with a door when open-
ing it or cancel opening of
the door, to reduce the pos-
sibility of a collision.
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 safe exit assist is a supple-
mentary system that, when the
vehicle is stopped, informs
occupants of the existence of
approaching vehicles and bicy-
cles. As this system alone can-
not be used to judge safety,
over-reliance on this system
may lead to an accident result-
ing in death or serious injury.
In certain situations, this system
may not function to its fullest
extent. Therefore it is necessary
for the occupants to visually
check for safety directly and using
the mirrors.
