static object detection and display
(warning buzzer sounds). Even at low speeds, there is a possibility that the object will come within 30 cm (1.0 ft.)
before the display is shown and the warning buzzer sounds.• It might be difficult to hear the buzzer
due to the volume of the audio system or air flow noise of the air conditioning system.
• It may be difficult to hear the sound of this system due to the buzzers of other systems.
■Objects which the system may not
be properly detected
The shape of the object may prevent the sensor from detecting it. Pay particular
attention to the following objects:
●Wires, fences, ropes, etc.
●Cotton, snow and other materials that absorb sound waves
●Sharply-angled objects
●Low objects
●Tall objects with upper sections pro-
jecting outwards in the direction of your vehicle
■Situations in which the system may not operate properly
Certain vehicle conditions and the sur- rounding environment may affect the ability of a sensor to correctly detect
objects. Particular instances where this may occur are listed below.
●There is dirt, snow, water drops or ice on a sensor. (Cleaning the sensors will resolve this problem.)
●A sensor is frozen. (Thawing the area will resolve this problem.)
In especially cold weather, if a sensor is frozen the sensor display may be displayed abnormally, or objects, such
as a wall, may not be detected.
●When a sensor or the area around a
sensor is extremely hot or cold.
●On an extremely bumpy road, on an
incline, on gravel, or on grass.
●When vehicle horns, vehicle detec-
tors, motorcycle engines, air brakes of large vehicles, the clearance sonar of other vehicles or other devices which
produce ultrasonic waves are near the vehicle
●A sensor is coated with a sheet of spray or heavy rain.
●If objects draw too close to the sensor.
●Pedestrians that are hard to reflect
ultrasonic waves (ex. skirts with gath- ers or frills).
●When objects that are not perpendicu-lar to the ground, not perpendicular to the vehicle traveling direction,
uneven, or waving are in the detection range.
●Strong wind is blowing
●When driving in inclement weather
such as fog, snow or a sandstorm
●When an object that cannot be
detected is between the vehicle and a detected object
●If an object such as a vehicle, motor-cycle, bicycle or pedestrian cuts in front of the vehicle or runs out from
the side of the vehicle
●If the orientation of a sensor has been
changed due to a collision or other impact
●When equipment that may obstruct a sensor is installed, such as a towing eyelet, bumper protector (an addi-
tional trim strip, etc.), bicycle carrier, or snow plow
●If the front of the vehicle is raised or lowered due to the carried load

■ECB (Electronically Con-
trolled Brake System)
The electronically controlled sys-
tem generates braking force corre-
sponding to the brake operation
■ABS (Anti-lock Brake System)
Helps to prevent wheel lock when
the brakes are applied suddenly, or
if the brakes are applied while driv-
ing on a slippery road surface
■Brake assist

braking force after the brake pedal
is depressed when the system
detects a panic stop situation
■VSC (Vehicle Stability Control)
Helps the driver to control skidding
when swerving suddenly or turning
on slippery road surfaces.
■VSC+ (Vehicle Stability Con-
trol+)
Provides cooperative control of the
ABS, TRC, VSC and EPS.
Helps to maintain directional stabil-
ity when swerving on slippery road
surfaces by controlling steering per-
formance.
■TRC (Traction Control)
Helps to maintain drive power and
prevent the drive wheels from spin-
ning when starting the vehicle or
accelerating on slippery roads
■Active Cornering Assist (ACA)
Helps to prevent the vehicle from
drifting to the outer side by perform-
ing inner wheel brake control when
attempting to accelerate while turn-
ing
■Hill-start assist control
Helps to reduce the backward
movement of the vehicle when
starting on an uphill
■EPS (Electric Power Steering)

●2 seconds at maximum elapsed after the brake pedal is released
■Sounds and vibrations caused by
the ABS, brake assist, VSC, TRC and hill-start assist control sys-tems
●A sound may be heard from the engine compartment when the brake
pedal is depressed repeatedly, when the hybrid system is started or just after the vehicle begins to move. This
sound does not indicate that a mal- function has occurred in any of these systems.
●Any of the following conditions may occur when the above systems are
operating. None of these indicates that a malfunction has occurred.• Vibrations may be felt through the
vehicle body and steering. • A motor sound may be heard also after the vehicle comes to a stop.
■ECB operating sound
ECB operating sound may be heard in the following cases, but it does not indi-cate that a malfunction has occurred.
●Operating sound heard from the engine compartment when the brake
pedal is operated.
●Motor sound of the brake system
heard from the front part of the vehicle when the driver’s door is opened.
●Operating sound heard from the engine compartment when one or two minutes passed after the stop of the
hybrid system.
■Active Cornering Assist operation sounds and vibrations
When the Active Cornering Assist is
operated, operation sounds and vibra-
tions may be generated from the brake
system, but this is not a malfunction.
■EPS operation sound
When the steering wheel is operated, a motor sound (whirring sound) may be
heard. This does not indicate a malfunc- tion.
■Automatic reactivation of TRC and VSC systems
After turning the TRC and VSC systems off, the systems will be automatically re-enabled in the following situations:
●When the power switch is turned off
●If only the TRC system is turned off, the TRC will turn on when vehicle speed increases.
If both the TRC and VSC systems are turned off, automatic re-enabling will not occur when vehicle speed
increases.
■Operating conditions of Active Cor- nering Assist
The system operates when the following
occurs.
●TRC/VSC can operate
●The driver is attempting to accelerate while turning
●The system detects that the vehicle is drifting to the outer side
●The brake pedal is released
■Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from overheating when there is frequent
steering input over an extended period of time. The steering wheel may feel heavy as a result. Should this occur,
refrain from excessive steering input or stop the vehicle and turn the hybrid sys-tem off. The EPS system should return
to normal within 10 minutes.
