■If a warning message is displayed on the multi-information display
A system may be temporarily unavailable or there may be a malfu nction in the sys-
tem.
●In the following situations, perform the actions specified in t he table. When the nor-
mal operating conditions are detected, the message will disappe ar and the system will become operational.
If the message does not disappear, contact any authorized Toyot a retailer or Toyota authorized repairer, or any reliable repairer.
●In the following situations, if the situation has changed (or t he vehicle has been
driven for some time) and the normal operating conditions are d etected, the mes- sage will disappear and the system will become operational.
SituationActions
When the area around a camera is cov-
ered with dirt, moisture (fogged up, cov-
ered with condensation, ice, etc.), or
other foreign matter
Using the wiper and A/C function,
remove the dirt and other attached mat-
ter. ( P.313, 318).
When the temperature around the front
camera is outside of the operational
range, such as when the vehicle is in the
sun or in an extremely cold environment
If the front camera is hot, such as after
the vehicle had been parked in the sun,
use the air conditioning system to
decrease the temperature around the
front camera.
If a sunshade was used when the vehicle
was parked, depending on its type, the
sunlight reflected from the surface of the
sunshade may cause the temperature of
the front camera to become excessively
high.
If the front camera is cold, such after the
vehicle is parked in an extremely cold
environment, use the air conditioning
system to increase the temperature
around the front camera.
The area in front of the front camera is
obstructed, such as when the hood is
open or a sticker is attached to the part of
the windshield in front of the front cam-
era.
Close the hood, remove the sticker, etc.,
to clear the obstruction.
When “Pre-Collision System Radar In
Self Calibration Unavailable See
Owner’s Manual” is displayed.
Check whether there is attached materi-
als on the radar sensor and radar sensor
cover, and if there is, remove it.

PCS (Pre-Collision System)*
The pre-collision system uses a rad ar sensor and front camera to
detect objects ( P.217) in front of the vehicle. When the system
determines that the possibility of a frontal collision with an object is
high, a warning operates to urge the driver to take evasive act ion
and the potential brake pressure is increased to help the drive r
avoid the collision. If the syste m determines that the possibility of a
frontal collision with an object is extremely high, the brakes are
automatically applied to help avoid the collision or help reduc e the
impact of the collision.
The pre-collision system can be disabled/enabled and the warnin g timing
can be changed. ( P.221)

buzzer sounds, the driver is warned and
the function is temporarily canceled.
This warning also operates in the same
way when the driver continuously oper-
ates the steering wheel only a small
amount.
The buzzer also sounds even if the alert
type is set to steering wheel vibration.
●When the system determines that the vehicle may deviate from the lane while driving around a curve while the
lane centering function is operating.
Depending on the vehicle condition and
road conditions, the warning may not
operate. Also, if the system determines
that the vehicle is driving around a
curve, warnings will occur earlier than
during straight-lane driving.
●When the system determines that the
driver is driving without holding the steering wheel while the steering wheel assist of the steering assist
function is operating.
If the driver continues to keep their
hands off of the steering wheel and the
steering wheel assist is operating, the
buzzer sounds and the driver is warned.
Each time the buzzer sounds, the con-
tinuing time of the buzzer becomes lon-
ger.
The buzzer also sounds even if the alert
type is set to steering wheel vibration.
■Vehicle sway warning function
When the system determines that the vehicle is swaying while the vehicle
sway warning function is operating, a buzzer sounds and a warning message urging the driver to rest and the symbol
shown in the illustration are simultane- ously displayed on the multi-information display.
Depending on the vehicle and road con-
ditions, the warning may not operate.
■Warning message
