Toyota parking assist-sensor
: If equipped
Toyota parking assist-sensor uses sensors in the corners and rear of
the vehicle to detect the distance between the vehicle and any obsta-
cles, and informs the driver of this distance using the warning
beeps.
Sensor types
Rear corner sensor
Back sensors
Toyota parking assist-sensor switch
Left-hand drive vehicles
On/off

LKA (Lane-Keeping Assist)
: If equipped
While driving on a freeway or motor highway that has lane markers,
this system recognizes the lanes using a camera as a sensor to
assist the driver with staying in the lane. The LKA system has two
functions.
Lane departure warning function
If the system judges that the vehicle may deviate from its lane, it
alerts the driver using rapid beeping, indications on the multi-
information display, and a sensory warning
* given via the steer-
ing wheel.
*: A slight steering torque is applied for a short period of time in
the direction of the center of the lane.
Lane keeping assist function
This function will be active when the vehicle-to-vehicle distance
control mode of the cruise control (P. 281) is set with vehicle
speed above approx. 72 km/h (approx. 45 mph) and while the
lane departure warning function is active. When the lane keep-
ing assist function is active, a slight steering torque will be
applied, to help the driver maintain the vehicle in a central posi-
tion within the lane.
While the lane keeping assist function is active, sensory warnings
will not occur.

Hands-free driving warning
If the steering wheel is not operated for about 15 seconds on a straight road
or about 5 seconds on a curve, the buzzer will beep twice, indicators on the
multi-information display will flash, and the lane keeping assist function will
be temporarily canceled. If you drive the vehicle with your hands lightly
touching the steering wheel, this may also be detected as hands-free driv-
ing.
When the vehicle has been parked in the sun
The LKA system functions may not be available for a while after driving has
started. In such cases, turn the LKA system off and turn it on again after nor-
mal temperature returns. When the temperature in the cabin decreases and
the temperature around the camera sensor becomes suitable for its opera-
tion, the functions will begin to operate.
Warning lights and messages for LKA
Warning lights and messages are used to indicate a system malfunction or
to inform the driver of the need for caution while driving. (P. 619)
CAUTION
Before using the LKA system
Do not rely on the LKA system to remain within a selected lane. The LKA
system is not designed to enable inattentive driving. The steering wheel
should be operated by the driver to maintain the vehicle in a suitable position
within its lane. Always drive carefully.

PCS (Pre-Crash Safety)
: If equipped
When the radar sensor detects possibility of a frontal collision, the
pre-crash safety systems such as the brakes and seat belts are
automatically engaged to lessen impact and injuries to occupants
as well as vehicle damage.
Pre-crash seat belts
If the pre-crash sensor detects that a collision is unavoidable,
the pre-crash safety 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. (P. 110)
However, when the VSC system is disabled, the system will not
operate in the event of skidding.
Pre-crash 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.
Pre-crash 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 system determines that a collision is unavoidable,
the brakes are automatically applied to reduce the collision
speed. Pre-crash braking can be disabled using the pre-crash
braking OFF switch.

position, speed, and heading of
the obstacles.

Situations in which the pre-crash safety 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 the axis of the radar is out of adjustment
When an extreme change in vehicle height occurs
When there is a malfunction in the system
Warning lights and/or warning messages will turn on or flash. (P. 624)
