■Hill-start assist control buzzer
●When hill-start assist control is activated, the buzzer will sound once.
●In the following situations, hill-start assist control will be canceled and the
buzzer will sound twice.
•No attempt is made to drive the vehicle within approximately 2 seconds
of releasing the brake pedal.
•Push the P position switch.
•The parking brake is applied.
•The brake pedal is depressed again.
•The brake pedal has been depressed for more than approximately 3
minutes.
■If the slip indicator light comes on
It may indicate a malfunction in the system. Contact your Toyota dealer.
CAUTION
■Hill-start assist control
●Do not overly rely on the hill-start assist control. Hill-start assist control
may not operate effectively on extremely steep inclines or roads covered
in ice.
●Unlike the parking brake, hill-start assist control is not intended to hold the
vehicle stationary for an extended period of time. Do not attempt to use
hill-start assist control to hold the vehicle on an incline for an extended
period of time, as doing so may lead to an accident.

PCS (Pre-Collision System)

: If equipped
When the radar sensor detects possibility of a frontal collision, the
pre-collision systems such as the brakes and seat belts are automat-
ically engaged to lessen impact as well as vehicle damage.
■Pre-collision seat belts (front seat belts 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 driver makes an emergency braking or
loses control of the vehicle. (oP. 1 6 2 )
However, when the VSC system is disabled, the system will not oper-
ate in the event of skidding.
■Pre-collision brake assist
When there is a high possibility of a frontal collision, the system applies
greater braking force in relation to how strongly the brake pedal is
depressed. The system may not warn the driver using a warning light,
warning display and buzzer when the system detects and judges brak-
ing operations.
■Pre-collision braking
When there is a high possibility of a frontal collision, the system warns
the driver using a warning light, warning display and buzzer. If the sys-
tem determines that a collision is unavoidable, the brakes are automat-
ically applied to reduce the collision speed. Pre-collision braking can be
disabled using the pre-collision braking off switch.

■The pre-collision system is operational when
●Pre-collision seat belts (operating conditions A):
•Vehicle speed is greater than about 19 mph (30 km/h).
•The system detects sudden braking or skidding.
•The front occupants are wearing a seat belt.
●Pre-collision seat belts (operating conditions B):
•Vehicle speed is greater than about 4 mph (5 km/h).
•The speed at which your vehicle is approaching the obstacle or the
vehicle running ahead of you is greater than about 19 mph (30 km/h).
•The front occupants are wearing a seat belt.
●Pre-collision brake assist:
•Vehicle speed is greater than about 19 mph (30 km/h).
•The speed at which your vehicle is approaching the obstacle or the
vehicle running ahead of you is greater than about 19 mph (30 km/h).

■Conditions that may trigger the system even if there is no possibility of
a collision
●When there is an object by the roadside at the entrance to a curve
●When passing an oncoming vehicle on a curve
●When driving over a narrow iron bridge
●When there is a metal object on the road surface
●When driving on an uneven road surface (nose up, nose down)
●When passing an oncoming vehicle on a left-turn
●When your vehicle rapidly closes on the vehicle in front
●When a grade separation/interchange, sign, billboard, or other structure
appears to be directly in the vehicle’s line of travel
●When the steep angle of the road causes a metal object located beneath
the road surface to be seen ahead of the vehicle
●When an extreme change in vehicle height occurs
●When the axis of the radar is out of adjustment
●When passing through certain toll gates
●When passing through an overpass
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 may 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,
bicycles, motorcycles, trees, or snowdrifts.
■Situations in which the pre-collision 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 inter-
section
●If a vehicle suddenly cuts in front of your vehicle, such as when overtak-
ing
●In inclement weather such as heavy rain, fog, snow or sand storms
●When your vehicle is skidding with the VSC system off
●When an extreme change in vehicle height occurs
●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, or if the system is tempo-
rarily unusable
Warning lights and/or warning messages will turn on or flash. (oP. 5 4 0 , 5 5 3 )

CAUTION
■Limitations of the pre-collision system
The driver is solely responsible for safe driving. Always drive safely, taking
care to observe your surroundings.
Do not use the pre-collision system instead of normal braking operations
under any circumstances. This system will not prevent collisions or lessen
damage or injuries in all cases. Do not overly rely on this system. Failure to
do so may cause an accident, resulting in death or serious injury.
This system has been designed to help avoid and reduce the impact of colli-
sions. However, the system operates differently depending on the situation
(oP. 3 4 2 , 3 4 3 ) . A s a r e s u l t , t h e s a m e l e v e l o f p e r f o r m a n c e m a y n o t b e
expected in all cases. Also, the pre-collision brakes may not operate if the
driver is depressing the brake pedal or turning the steering wheel, as the
system will determine such conditions as collision avoidance operations.

CAUTION
■Cautions regarding the assist contents of the system
By means of alarms and brake control, the pre-collision system is intended
to assist the driver in avoiding collisions through the process of LOOK-
JUDGE-ACT. There are limits to the degree of assistance the system can
provide, so please keep in mind the following important points.
●Assisting the driver in watching the road
The pre-collision system is only able to detect obstacles directly in front of
the vehicle, and only within a limited range. It is not a mechanism that
allows careless or inattentive driving, and it is not a system that can assist
the driver in low-visibility conditions. It is still necessary for the driver to
pay close attention to the vehicle’s surroundings.
●Assisting the driver in making correct judgement
When attempting to estimate the possibility of a collision, the only data
available to the pre-collision system is that from obstacles it has detected
directly in front of the vehicle. Therefore, it is absolutely necessary for the
driver to remain vigilant and to determine whether or not there is a possi-
bility of collision in any given situation.
●Assisting the driver in taking action
The pre-collision system’s braking assist feature is designed to help
reduce the severity of a collision, and so only acts when the system has
judged that a collision is unavoidable. This system is not capable of auto-
matically avoiding a collision or bringing the vehicle to a stop safely with-
out appropriate operations performed by the driver. For this reason, when
encountering a dangerous situation the driver must take direct and imme-
diate action in order to ensure the safety of all involved.

CAUTION
■When the sensor may not be correctly detecting the vehicle ahead
Apply the brakes as necessary in any of the following situations.
●When water or snow thrown up by the surrounding vehicles hinders the
functioning of the sensor
●When your vehicle is pointing upwards (caused by a heavy load in the lug-
gage compartment etc.)
●Ve h i c l e s t h a t c u t i n s u d d e n l y
●Ve h i c l e s w i t h s m a l l r e a r e n d s ( t r a i l e r s w i t h n o l o a d o n b o a r d e t c . )
●Motorcycles traveling in the same lane
■Handling the radar sensor
Observe the following to ensure the pre-collision system can function effec-
tively:
●Keep the sensor and grille cover clean at all times.
Clean the sensor and grille cover with a soft cloth so you do not mark or
damage them.
●Do not subject the sensor or surrounding area to a strong impact.
If the sensor moves even slightly off position, the system may become
inaccurate or malfunction. If the sensor or surrounding area is subject to a
strong impact, always have the area inspected and adjusted by your
To y o t a d e a l e r .
●Do not disassemble the sensor.
●Do not attach accessories or stickers to the sensor, grille cover or sur-
rounding area.
●Do not modify or paint the sensor and grille cover.
