sensor TOYOTA COROLLA 2022 (in English) Owner's Manual

2024-5. Using the driving support systems
*: If equipped
The system can detect the follow-
ing:
 Vehicles
 Bicyclists
 Pedestrians
■Pre-collision warning
When the system determines that
the possibility of a frontal collision is
high, a buzzer will sound and a
warning mess age will be displayed
on the multi-information display to
urge the driver to take evasive
action.
■Pre-collision brake assist
When the system determines that
the possibility of a frontal collision is
high, the system applies greater
braking force in relation to how
strongly the brake pedal is
depressed.
■Pre-collision braking
If the system determines that the
possibility of a frontal collision is
extremely high, the brakes are
automatically applied to help avoid
the collision or reduce the impact of
the collision.
PCS (Pre-Collision Sys-
tem)*
The pre-collision system uses
a radar sensor and front cam-
era to detect objects ( P.205)
in front of the vehicle. When
the system determines that the
possibility of a frontal collision
with an object is high, a warn-
ing operates to urge the driver
to take evasive action and the
potential brake pressure is
increased to help the driver
avoid the collision. If the sys-
tem determines that the possi-
bility of a frontal collision with
an object is extremely high, the
brakes are automatically
applied to help avoid the colli-
sion or help reduce the impact
of the collision.
The pre-collision system can
be disabled/enabled and the
warning timing can be
changed. ( P.204)

■Enabling/disabling the pre-col-
lision system
The pre-collisio n system can be
enabled/disabled on ( P.538)
of the multi-information display.
The system is auto matically enabled
each time the engine switch is turned to
ON.
If the system is disabled, the PCS
warning light will turn on and a
message will be di splayed on the
multi-information display.
■Changing the pre-collision
warning timing
The pre-collision warning timing
can be changed on ( P.538) of
the multi-information display.
The warning timing setting is retained
when the engine switch is turned off.
However, if the pr e-collision system is
disabled and re-enabled, the operation
timing will return to the default setting
(middle).

■Before using dynamic radar
cruise control with full-speed
range
●Driving safely is the sole responsi-
bility of the driver. Do not rely solely
on the system, and drive safely by always paying careful attention to
your surroundings.
●The dynamic radar cruise control
with full-speed range provides driv-
ing assistance to reduce the driver’s burden. However, there are
limitations to the assistance pro-
vided.
Read the following conditions care-
fully. Do not overly rely on this system
and always drive carefully.

■Situations unsuitable for
dynamic radar cruise control
with full-speed range
Do not use dynamic radar cruise con-
trol with full-speed range in any of the
following situations. Doing so may result in inappropriate speed control
and could cause an accident resulting
in death or serious injury.
●Roads where there are pedestrians,
cyclists, etc.
●In heavy traffic
●On roads with sharp bends
●On winding roads
●On slippery roads, such as those
covered with rain, ice or snow
●On steep downhills, or where there
are sudden changes between sharp
up and down gradients
Vehicle speed may exceed the set
speed when driving down a steep hill.
●At entrances to freeways and high-
ways
●When weather conditions are bad
enough that they may prevent the
sensors from detecting correctly (fog, snow, sandstorm, heavy rain,
etc.)
●When there is rain, snow, etc. on
the front surface of the radar or
front camera
●In traffic conditions that require fre-
quent repeated acceleration and deceleration
●When your vehicle is towing a trailer or during emergency towing
●When an approach warning buzzer is heard often

■When the vehicle stops while fol-
low-up cruising
●Pressing the “+RES” switch while the
vehicle ahead stops will resume fol- low-up cruising if the vehicle ahead
starts off within approximately 3 sec-
onds after the switch is pressed.
●If the vehicle ahead starts off within 3
seconds after your vehicle stops, fol- low-up cruising will be resumed.
■Automatic cancelation of vehi-
cle-to-vehicle distance control
mode
Vehicle-to-vehicle distance control mode
is automatically canceled in the follow-
ing situations.
●VSC is activated.
●TRC is activated for a period of time.
●When the VSC or TRC system is turned off.
●The sensor cannot detect correctly because it is covered in some way.
●Pre-collision braking is activated.
●The parking brake is operated.
●The vehicle is stopped by system con-
trol on a steep incline.
●The following are detected when the
vehicle has been st opped by system
control: • The driver is not wearing a seat belt.
• The driver’s door is opened.
• The vehicle has been stopped for about 3 minutes
If vehicle-to-vehicle distance control
mode is automatically canceled for any reasons other than the above, there
may be a malfunction in the system.

or Toyota authorized repairer, or any reli- able repairer.
■Automatic cancelation of constant
speed control mode
Constant speed control mode is auto- matically canceled in the following situa-
tions:
●Actual vehicle speed is more than
approximately 16 km/h (10 mph)
below the set vehicle speed.
●Actual vehicle speed falls below
approximately 30 km/h (20 mph).
●VSC is activated.
●TRC is activated for a period of time.
●When the VSC or TRC system is turned off.
●Pre-collision braking is activated.
If constant speed control mode is auto-
matically canceled for any reasons other
than the above, there may be a malfunc- tion in the system. Contact any author-
ized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
■The Dynamic Radar Cruise Control with Road Sign Assist may not
operate properly when
As the Dynamic Radar Cruise Control with Road Sign Assist may not operate
properly in conditions in which RSA may
not operate or detect correctly ( P.257), when using this function,

to inform the driver of the need for cau-
tion while driving. If a warning message is shown on the multi-information dis-
play, read the message and follow the
instructions. ( P.200, 480)
■When the sensor may not be cor- rectly detecting the vehicle ahead
In the case of the following and depend-
ing on the conditions, operate the brake pedal when deceleration of the system
is insufficient or operate the accelerator
pedal when acceleration is required.
As the sensor may not be able to cor-
rectly detect these types of vehicles, the
approach warning ( P.233) may not be activated.
●Vehicles that cut in suddenly
●Vehicles traveling at low speeds
●Vehicles that are not moving in the
same lane
●Vehicles with small rear ends (trailers
with no load on board, etc.)
●Motorcycles traveling in the same lane
●When water or snow thrown up by the surrounding vehicles hinders the
detecting of the sensor
●When your vehicle is pointing
upwards (caused by a heavy load in
the luggage compartment, etc.)
●Preceding vehicle has an extremely
high ground clearance
■Conditions under which the vehi-
cle-to-vehicle distance control
mode may not function correctly
In the case of the following conditions,
operate the brake pedal (or accelerator
pedal, depending on the situation) as necessary.
As the sensor may not be able to cor-
rectly detect vehicl es ahead, the system may not operate properly.
●When the road curves or when the lanes are narrow
●When steering wheel operation or your position in the lane is unstable
●When the vehicle ahead of you decel-erates suddenly
●When driving on a road surrounded by a structure, such as in a tunnel or on a
bridge
●While the vehicle speed is decreasing to the set speed after the vehicle
