2023 TOYOTA COROLLA CROSS brake sensor

2704-5. Using the driving support systems
If the sensors detect a static object, such as a wall, in the travelling
direction of the vehicle and the system determines that a collision
may occur due to the vehicle suddenly moving forward due to an
accidental accelerator pedal operation, the vehicle moving the unin-
tended direction due to the wrong shift position, or while park ing or
traveling at low speeds, the system will operate to lessen the impact
with the detected static object and reduce the resulting damage .
The system operates in the follow ing situations when a static object
is detected in the traveling direction of the vehicle.
■When traveling at a low speed and the brake pedal is not
depressed, or is depressed late
■When the accelerator pedal is depressed excessively

■The system will operate when
The function will operate when the
driving assist information indicator is
not illuminated or flashing ( P.74,
397) and all of the following condi-
tions are met:
●Engine output restriction control
• PKSB (Parking Support Brake)
system is enabled.
• The vehicle speed is approxi- mately 9 mph (15 km/h) or less.
• There is a static object in the trav- eling direction of the vehicle and
approximately 6 to 13 ft. (2 to 4 m)
away.
• The PKSB (Parking Support
Brake) determines that a stron-
ger-than-normal brake operation
is necessary to avoid a collision.
●Brake control
• Engine output restriction control is
operating.
• The PKSB (Parking Support Brake) determines that an imme-
diate brake operation is necessary
to avoid a collision.
■The system will stop operating
when
The function will stop operating if
any of the following conditions are
met:
●Engine output restriction control
• PKSB (Parking Support Brake) system is disabled.
• The system determines that the
collision has become avoidable
with normal brake operation.
• The static object is no longer
approximately 6 to 13 ft. (2 to 4 m)
away from the vehicle or in the
traveling direction of the vehicle.
●Brake control
• PKSB (Parking Support Brake)
system is disabled.

2724-5. Using the driving support systems
• Approximately 2 seconds have elapsed since the vehicle was
stopped by brake control.
• The brake pedal is depressed after the vehicle is stopped by
brake control.
• The static object is no longer approximately 6 to 13 ft. (2 to 4 m)
away from the vehicle or in the
traveling direction of the vehicle.
■Detection range
The detection range of the system
differs from the detection range of
the intuitive parking assist. ( P.263) Therefore, even if the intuitive park-
ing assist detects an object and pro-
vides a warning, the PKSB (Parking
Support Brake) may not start oper-
ating.
■Situations in which the system
may not operate properly
 P.261
■Situations in which the system
may operate even if there is no
possibility of a collision
 P.262
If a rear radar sensor detects a vehicle approaching from the right or
left at the rear of the vehicle and the system determines that the pos-
sibility of a collision is high, this function will perform bra ke control to
reduce the likelihood of an impact with the approaching vehicle .
This function will operate in situations such as the following if a vehi-
cle is detected in the traveling direction of the vehicle.
■When reversing, a vehicle is approaching and the brake pedal
is not depressed, or is depressed late

ing, during cornering, on a
uphill, when starting off, during
acceleration, on a slippery roads
due to snow or rain, thus con-
tributing to stable operability and
driving stability.
■The Secondary Collision
Brake
When the SRS airbag sensor
detects a collision and the sys-
tem operates, the brakes and
brake lights are automatically
controlled to reduce the vehicle
speed and help reduce the pos-
sibility of further damage due to
a secondary collision.
■When the TRAC/VSC systems
are operating
The slip indicator light will flash
while the TRAC/VSC systems are
operating.
■Disabling the TRAC system
If the vehicle gets stuck in mud, dirt
or snow, the TRAC system may
reduce power from the engine to the
wheels. Pressing to turn the
system off may mak e it easier for
you to rock the vehicle in order to
free it.
To turn the TRAC system off, quickly
press and release .
The “Traction Control Turned OFF” will be shown on the multi-informa-
tion display.
Press again to turn the system
back on.
■Turning off both TRAC and VSC
systems
To turn the TRAC and VSC systems
off, press and hold for more
than 3 seconds while the vehicle is
stopped.
The VSC OFF indicator light will
come on and the “Traction Control
Turned OFF” will be shown on the
multi-information display.
*
Press again to turn the system
back on.
*: PCS will also be disabled (only
Pre-Collision warning is avail-
able). The PCS warning light will
come on and a message will be
displayed on the multi-information
display. ( P.198)
■When the message is dis-
played on the multi-information
display showing that TRAC has
been disabled even if has
not been pressed
TRAC is temporary deactivated. If
the information continues to show,
contact your Toyota dealer.
■Operating conditions of
hill-start assist control

to normal within 10 minutes.
■Secondary Collision Brake
operating conditions
The system operates when the SRS
airbag sensor detects a collision
while the vehicle is in motion.
However, the system does not oper-
ate when the components are dam-
aged.
■Secondary Collision Brake
automatic cancellation
The system is automatically can-
celed in any of th e following situa-
tions.
●The vehicle speed drops below
approximately 0 mph (0 km/h)
●A certain amount o f time elapses
during operation
●The accelerator pedal is
depressed a large amount
WARNING
■The ABS does not operate
effectively when
●The limits of tire gripping perfor-
mance have been exceeded
(such as excessively worn tires
on a snow covered road).
●The vehicle hydroplanes while
driving at high speed on wet or
slick roads.
■Stopping distance when the
ABS is operating may exceed
that of normal conditions
The ABS is not designed to
shorten the vehicle’s stopping dis-
tance. Always maintain a safe dis-
tance from the vehicle in front of
you, especially in the following sit-
uations:
●When driving on d irt, gravel or
snow-covered roads
●When driving with tire chains
●When driving over bumps in the
road
●When driving over roads with
potholes or uneven surfaces
■TRAC/VSC may not operate
effectively when
Directional control and power may
not be achievable while driving on
slippery road surfaces, even if the
TRAC/VSC system is operating.
Drive the vehicle carefully in con-
ditions where stability and power
may be lost.
■Active Cornering Assist does
not operate effectively when
●Do not overly rely on Active
Cornering Assist. Active Corner-
ing Assist may not operate
effectively when accelerating
down slopes or driving on slip-
pery road surfaces.
●When Active Corn ering Assist
frequently operates, Active Cor-
nering Assist may temporarily
stop operating to ensure proper
operation of the brakes, TRAC
and VSC.
■Hill-start assist control does
not operate effectively when
●Do not overly rely on hill-start
assist control. Hill-start assist
control may not operate effec-
tively on steep inclines and
roads covered with ice.
●Unlike the parking brake,
hill-start assist control is not
intended to hold the vehicle sta-
tionary for an extended period
of time. Do not attempt to use
hill-start assist control to hold
the vehicle on an incline, as
doing so may lead to an acci-
dent.

3987-2. Steps to take in an emergency
■Parking brake indicator
■Brake hold operated indicator (warning buzzer)
■Warning buzzer
In some cases, the buzzer may not
be heard due to being in a noisy
location or audio sound.
■Front passenger detection sen-
sor, seat belt reminder and
warning buzzer
●If luggage is placed on the front
passenger seat, the front passen-
ger detection sensor may cause
the warning light to flash and the
warning buzzer to sound even if a
passenger is not sitting in the
seat.
●If a cushion is placed on the seat,
the sensor may n ot detect a pas-
senger, and the warning light may
not operate properly.
■SRS warning light
This warning light indicates prob-
lems with the following:
●Airbag sensor assembly
●Front impact sensors

sun, use the air conditioning sys-
tem to decrease the temperature
around the front camera
• If a sunshade was used when the vehicle was parked, depending on
its type, the sunlight reflected from
the surface of the sunshade may
cause the temperature of the front
camera to become excessively
high
• If the front camera is cold, such after the vehicle is parked in an
extremely cold environment, use
the air conditioning system to
increase the temperature around
the front camera
