2023 TOYOTA COROLLA CROSS HYBRID warning

2744-5. Using the driving support systems
*: If equipped
The system can detect the fol-
lowing as detectable objects.
(Detectable objects differ
depending on the function.)
Static Objects Front and Rear
of the vehicle ( P.279)
 Moving Vehicles Rear of the
Vehicle ( P.281)
PKSB (Parking Sup-
por t Brake)*
The PKSB (Parking Support
Brake) consists of the fol-
lowing functions that oper-
ate when driving at a low
speed or backing up, such
as when parking. When the
system determines that the
possibility of a collision
with a detected object is
high, a warning operates to
urge the driver to take eva-
sive action. If the system
determines that the possi-
bility of a collision with a
detected object is extremely
high, the brakes are auto-
matically applied to help
avoid the collision or help
reduce the impact of the col-
lision.

Brake) system
WARNING
■Cautions regarding the use of
the system
Do not overly rely on the system,
as doing so may lead to an acci-
dent.
Always drive while checking the
safety of the surroundings of the
vehicle.
Depending on the vehicle and
road conditions, weather, etc., the
system may n ot operate.
The detection cap abilities of sen-
sors and radars are limited.
Always drive while checking the
safety of the surroundings of the
vehicle.
●The driver is solely responsible
for safe driving. Always drive
carefully, taking care to observe
your surroundings. The PKSB
(Parking Support Brake) system
is designed to provide support
to lessen the severity of colli-
sions. However, it may not oper-
ate in some situations.
●The PKSB (Parki ng Support
Brake) system is not designed
to stop the vehicle completely.
Additionally, even if the system
has stopped the vehicle, it is
necessary to depress the brake
pedal immediately as brake
control will be canceled after
approximately 2 seconds.
●It is extremely dangerous to
check the system operations by
intentionally driving the vehicle
into the direction of a wall, etc.
Never attempt such actions.

Driving
■Active Cornering Assist opera-
tion sounds and vibrations
When the Active Cornering Assist is
operated, operation sounds and
vibrations may b e generated from
the brake system, but this is not a
malfunction.
■EPS operation sound
When the steering wheel is oper-
ated, a motor sound (whirring
sound) may be heard. This does not
indicate a malfunction.
■Automatic reactivation of TRAC
and VSC systems
After turning the TRAC and VSC
systems off, the systems will be
automatically re-enabled in the fol-
lowing situations:
●When the power switch is turned
off
●If only the TRAC system is turned
off, the TRAC will turn on when
vehicle speed increases
If both the TRAC and VSC sys-
tems are turned off, automatic
re-enabling will not occur when
vehicle speed increases.
■Operating conditions of Active
Cornering Assist
The system operates when the fol-
lowing occurs.
●TRAC/VSC can operate
●The driver is at tempting to accel-
erate while turning
●The system detects that the vehi-
cle is drifting to the outer side
●The brake pedal is released
■Reduced effectiveness of the
EPS system
The effectiveness of the EPS sys-
tem is reduced to prevent the sys-
tem from overheating when there is
frequent steering input over an
extended period of time. The steer-
ing wheel may feel heavy as a
result. Should this occur, refrain
from excessive steering input or
stop the vehicle and turn the hybrid system off. The EPS system should
return 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 of 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 veh icle in front of
you, especially in the following sit-
uations:
●When driving on dirt, gravel or
snow-covered roads
●When driving with tire chains

2884-5. Using the driving support systems
WARNING
●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 Cornering 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.
■When the TRAC/ABS/VSC is
activated
The slip indicator light flashes.
Always drive carefully. Reckless
driving may cause an accident.
Exercise particula r care when the
indicator light flashes.
■When the TRAC/VSC systems
are turned off
Be especially careful and drive at
a speed appropriate to the road
conditions. As these are the sys-
tems to help ensure vehicle stabil-
ity and driving force, do not turn
the TRAC/VSC systems off
unless necessary.
■Replacing tires
Make sure that all tires are of the
specified size, brand, tread pat-
tern and total load capacity. In
addition, make sure that the tires
are inflated to the recommended
tire inflation p ressure level.
The ABS, TRAC and VSC sys-
tems will not functi on correctly if
different tires are installed on the
vehicle.
Contact your Toyota dealer for fur-
ther information when replacing
tires or wheels.
■Handling of tires and the sus-
pension
Using tires with any kind of prob-
lem or modifying the suspension
will affect the driving assist sys-
tems, and may cause a system to
malfunction.
■Secondary Collision Brake
Do not rely solely upon the Sec-
ondary Collision Brake. This sys-
tem is designed to help reduce
the possibility of further damage
due to a secondary collision, how-
ever, that effect changes accord-
ing to various conditions. Overly
relying on the system may result
in death or serious injury.
