2020 TOYOTA CAMRY HYBRID brake sensor

2884-5. Using the driving support systems
◆ECB (Electronically Controlled Brake System)
The electronically controlled system generates braking force co rre-
sponding to the brake operation
◆ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenl y,
or if the brakes are applied while driving on a slippery road surface
◆Brake assist
Generates an increased level of braking force after the brake p edal
is depressed when the system de tects a panic stop situation
◆VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or
turning on slippery road surfaces.
◆Enhanced VSC (Enhanced Vehicle Stability Control)
Provides cooperative control of the ABS, TRAC, VSC and EPS.
Helps to maintain directional stability when swerving on slippe ry
road surfaces by controlling steering performance.
◆Secondary Collision Brake
When the airbag sensor detects a collision and the system oper-
ates, the brakes and stop light s are automatically controlled to
reduce the vehicle speed and hel p reduce the possibility of further
damage due to a secondary collision
◆TRAC (Traction Control)
Helps to maintain drive power and prevent the drive wheels from
spinning when starting the vehicl e or accelerating on slippery roads
Driving assist systems
To keep driving safety and perf ormance, the following systems
operate automatically in respon se to various driving situations.
Be aware, however, that these systems are supplementary and
should not be relied upon too heav ily when operating the vehi-
cle.

■Automatic reactivation of TRAC and VSC systems
After turning the TRAC and VSC systems off, the systems will be automati-
cally re-enabled in the following situations:
● When the power switch is turned off
● If only the TRAC system is turned off, the TRAC will turn on wh en vehicle
speed increases
If both the TRAC and VSC systems are turned off, automatic re-e nabling will
not occur when vehicle speed increases
■ Secondary Collision Brake operating conditions
The system operates when the SRS airbag sensor detects a collis ion while
the vehicle is in motion.
However, the system does not operate in any of the following si tuations.
● The vehicle speed is below 6 mph (10 km/h)
● Components are damaged
■ Secondary Collision Brake automatic cancellation
The Secondary Collision Brake is automatically canceled in the following situ-
ations:
●The vehicle speed drops below approximately 6 mph (10 km/h)
● A certain amount of time elapses during operation
● The accelerator pedal is depressed a large amount
■ Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the s ystem from
overheating when there is frequent steering input over an exten ded period of
time. The steering wheel may feel heavy as a result. Should thi s 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.

■Sensor detection information
●The sensor’s detection areas are limited to the areas around th e vehicle’s
bumper.
● Depending on the shape of the object and other factors, the det ection dis-
tance may shorten, or detection may be impossible.
● Objects may not be detected if they are too close to the sensor .
● There will be a short delay between object detection and displa y. Even at
slow speeds, there is a possibility that the object will come w ithin the sen-
sor’s detection areas before the display is shown and the buzze r sounds.
● Thin posts or objects lower than the sensor may not be detected when
approached, even if they have been detected once.
● It might be difficult to hear beeps due to the volume of audio system or air
flow noise of the air conditioning system.
■ If “Parking Assist Unavailable Please Clean Parking Assist Sens or” is
displayed on the multi-information display
A sensor may be dirty or covered with snow or ice. In such case s, if it is
removed from the sensor, the system should return to normal.
Also, due to the sensor being frozen at low temperatures, a mal function dis-
play may appear or an object may not be detected. If the sensor thaws out,
the system should return to normal.
■ If “Parking Assist Unavailable” is displayed on the multi-infor mation dis-
play
Water may be continuously flowing over the sensor surface, such as in a
heavy rain. When the system determines that it is normal, the system will
return to normal.

WARNING
■ When using the intuitive parking assist
Observe the following precautions.
Failing to do so may result in the vehicle being unable to be d riven safely
and possibly cause an accident.
● Do not use the sensor at speeds in excess of 6 mph (10 km/h).
● The sensors’ detection areas and reaction times are limited. When moving
forward or reversing, check the areas surrounding the vehicle ( especially
the sides of the vehicle) for safety, and drive slowly, using t he brake to
control the vehicle’s speed.
● Do not install accessories within the sensors’ detection areas.

WARNING
■Sensors
Certain vehicle conditions and the surrounding environment may affect the
ability of a sensor to correctly detect an object. Particular instances where
this may occur are listed below.
● There is dirt, snow or ice on the sensor. (Wiping the sensors w ill resolve
this problem.)
● The sensor is frozen. (Thawing the area will resolve this probl em.)
In especially cold weather, if a sensor is frozen the screen ma y show an
abnormal display, or objects may not be detected.
● The sensor is covered in any way.
● The vehicle is leaning considerably to one side.
● On an extremely bumpy road, on an incline, on gravel, or on grass.
● The vicinity of the vehicle is noisy due to vehicle horns, moto rcycle
engines, air brakes of large vehicles, or other loud noises pro ducing ultra-
sonic waves.
● There is another vehicle equipped with parking assist sensors i n the vicin-
ity.
● The sensor is coated with a sheet of spray or heavy rain.
● The sensor is drenched with water on a flooded road.
● The vehicle is equipped with a fender pole or wireless antenna.
● Towing eyelets are installed.
● The bumper or sensor receives a strong impact.
● The vehicle is approaching a tall or curved curb.
● The detection range is reduced due to an object such as a sign.
● In harsh sunlight or intense cold weather.
● The area directly under the bumpers is not detected.
● If objects draw too close to the sensor.
● A non-genuine Toyota suspension (lowered suspension, etc.) is i nstalled.
● A backlit license plate is installed.
In addition to the examples above, there are instances in which , because of
their shape, signs and other objects may be judged by a sensor to be closer
than they are.

Driving
The system will operate in situations such as the following if an 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
Intelligent Clearance Sonar (ICS)
: If equipped
If a collision with an object ma y occur due to the vehicle sud-
denly moving forward due to an accidental accelerator pedal
operation, the vehicle moving th e unintended direction due to
the wrong shift position being se lected, or while parking or trav-
eling at low speeds, the sensors detect objects, such as a wall ,
in the traveling direction of t he vehicle, and the system opera tes
to lessen an impact with an object and reduce the resulting dam -
age.

■Re-enabling the Intellig ent Clearance Sonar system
To re-enable the Intelligent Clearance Sonar system when it is disabled due
to operation of the Intelligent Clearance Sonar function, either enable the sys-
tem again (P. 320), or turn the power switch off and then back to ON mode.
Additionally, if the object becomes no longer in the traveling direction of the
vehicle or if the traveling direction of the vehicle changes (such as changing
from moving forward to backing up, or from backing up to moving forward),
the system will be re-enabled automatically.
■ Objects that the Intelligent Clearance Sonar function may not d etect
The sensors may not be able to detect certain objects, such as the following.
● Cotton cloth, snow, and other materials that are poor reflector s of ultrasonic
waves.
(People may also not be detected depending on the type of cloth ing they are
wearing.)
● Objects which are not perpendicular to the ground, are not perp endicular to
the traveling direction of the vehicle, are uneven or are wavin g.
● Low objects
● Thin objects such as wires, fences, ropes and signposts
● Objects that are extremely close to the bumper
■ Situations in which the Intelligent Clearance Sonar may not ope rate
properly
When the shift lever is in N
■ Intuitive parking assist buzzer
Regardless of whether the intuitive parking assist system is en abled or not
( P. 309), if the Intelligent Clearance Sonar system is enabled ( P. 320),
the front or rear sensors detect an object and brake control is performed, the
intuitive parking assist buzzer will sound to notify the driver of the approxi-
mate distance to the object.
