Example of follow-up cruising 
When following a vehicle driving slower than the set speed 
The system continues follow-up cruising while adjusting for changes in the
speed of the vehicle ahead in order to maintain the vehicle-to-vehicle dis-
tance set by the driver. 
Example of acceleration 
When there are no longer any vehicles ahead driving slower than
the set speed 
The system accelerates until the set speed is reached. The system then
returns to constant speed cruising. 
When your vehicle is too close to a  vehicle ahead, and sufficient auto-
matic deceleration via the cruise control is not possible, the display
will flash and the buzzer will sound to alert the driver. An example of
this would be if another driver cuts in  front of you while you are follow-
ing a vehicle. Apply the brakes to ensure an appropriate vehicle-to-
vehicle distance.
■Warnings may not occur when
In the following instances, there is a possibility that the warnings will
not occur:
● When the speed of the vehicle  ahead matches or exceeds your
vehicle speed
● When the vehicle ahead is traveling at an extremely slow speed
● Immediately after the crui se control speed was set
● At the instant the accelerator is applied

Automatic cancelation of constant speed control
The cruise control will stop maintaining  the vehicle speed in the following situ-
ations:
● Actual vehicle speed is more than approximately 10 mph (16 km/h) below
the set vehicle speed.
At this time, the memorized set speed is not retained.
● Vehicle speed falls below approximately 25 mph (40 km/h).
● VSC is activated.
■ Radar sensor and grille cover
Always keep the sensor and grille cover clean to ensure that the vehicle-to-
vehicle distance control operates properly. (Some obstructions, such as
snow, ice and plastic objects, cannot be detected by the obstruction sensor.)
Dynamic radar cruise control is canceled if an obstruction is detected. 
■ Warning messages and buzzers for dynamic radar cruise control
Warning messages and buzzers are used to indicate a system malfunction or
to inform the driver of the need for caution while driving. The following actions
may solve the problem.
●When a message indicating to perform system check is displayed:
Press the “ON-OFF” button once to deactivate the system, and then press
the button again to reactivate the system.
● When a message indicating to clean the radar sensor is displayed: Dirt, ice,
etc. is on the radar sensor surface. Clean the sensor.
● When a message indicating that the cruise control is not available is dis-
played: If the wipers are operating at high speed (including when the wiper
switch is in the AUTO position), the radar cruise control is not available. Use
the cruise control when it is possible to drive without operating the wipers at
high speed.
If the warning message remains on even after the above actions have been
performed, the system may be malfunctioning. Have the vehicle inspected by
your Toyota dealer. Grille cover

The slip indicator light will flash
while the TRAC/VSC/ABS/hill-
start assist control systems are
operating.
If the vehicle gets stuck in mud, dirt or snow, the TRAC systems may
reduce power from the hybrid syst em to the wheels. Pressing the
switch to turn the system off may  make it easier for you to rock the
vehicle in order to free it.
To turn the TRAC system off,
quickly press and release the
switch.

■Turning off both TRAC/VSC systems
To turn the TRAC/VSC systems off, press and hold the switch for more than 3
seconds while the vehicle is stopped.
The VSC OFF and “TRAC OFF” indica tor lights will come on and the mes-
sage will be shown on the multi-information display.
Press the switch again to turn the systems back on.
■ When the message is displayed on th e multi-information display show-
ing that TRAC has been disabled and “TRAC OFF” indicator light comes

TRAC and hill-start assist control cannot be operated. Contact your Toyota
dealer.
■ Sounds and vibrations caused by the ABS, brake assist, TRAC, VSC
systems
●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 malfunction 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 after the vehicle comes to a stop.
■ EPS operation sound
When the steering wheel is operated, 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 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 when vehicle
speed increases
If both the TRAC and VSC systems are turned off, automatic re-enabling will
not occur when vehicle speed increases.
■ 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 system
off. The effectiveness of the EPS system  will be restored after a short while.

◆Pre-collision seat belts (front seats only)
If the pre-collision sensor detects that a collision is unavoidable, the
pre-collision system will  retract the seat belt before the collision
occurs.
The same will happen if the driv er makes an emergency braking or
loses control of the vehicle. ( P. 31) 
However, when the VSC system  is disabled, the system will not
operate in the event of skidding.
◆Pre-collision brake assist
When there is a high po ssibility of a frontal collision, the system
applies greater braking force in relation to how strongly the brake
pedal is depressed.
◆Pre-collision braking
When there is a high po ssibility of a frontal collision, the system
warns the driver using a warning light, warning display and buzzer.
If the system determines that a collision is unavoidable, the brakes
are automatically applied to  reduce the collision speed.
PCS (Pre-Collision System)
: If equipped
When the radar sensor detects pos sibility of a frontal collision,
the pre-collision system such as the brakes and seat belts are
automatically engaged to lessen impact as well as vehicle dam-
age.
The pre-collision system can be tu rned on and off as necessary by
operating the switch. ( P. 246)

2484-5. Using the driving support systems
AVALON_HV_U (OM41451U)When the system is activated in the situations described above, there is also
a possibility that the seat belts will retract quickly and the brakes will be
applied with a force greater than normal. When the seat belt is locked in the
retracted position, stop the vehicle in a safe place, release the seat belt and
refasten it.
■ Obstacles not detected
The sensor cannot detect plastic obstacles such as traffic cones. There may
also be occasions when the sensor cannot detect pedestrians, animals, bicy-
cles, motorcycles, trees, or snowdrifts. 
■ Situations in which the pre-collis ion system does not function properly
The system may not function effectively in situations such as the following:
● On roads with sharp bends or uneven surfaces
● If a vehicle suddenly moves in front of your vehicle, such as at an intersec-
tion
● If a vehicle suddenly cuts in front of your vehicle, such as when overtaking
● In inclement weather such as heavy rain, fog, snow or sand storms
● When your vehicle is skidding such as the VSC system off
● When your vehicle is steeply inclined
● When the axis of the radar is out of adjustment
■ Automatic cancelation of  the pre-collision system
When a malfunction occurs due to sensor contamination, etc. that results in
the sensors being unable to detect obstacles, the pre-collision system will be
automatically disabled. In this case, the system will not activate even if there
is a collision possibility.
■ When there is a malfunction in the system
“PCS” warning light will flash and warning messages will be displayed. 
(P. 414) Have the vehicle inspected by your Toyota dealer immediately.
