■Hands off steering wheel warning
In the following situations, a warning
message urging the driver to hold the
steering wheel and the symbol shown in
the illustration are displayed on the
multi-information display to warn the
driver. The warning stops when the sys-
tem determines that the driver holds the
steering wheel. Always keep your hands
on the steering wheel when using this
system, regardless of warnings.
●When the system determines that the
driver is driving without holding the
steering wheel while the system is
operating
If the driver continues to keep their
hands off of the steering wheel, the
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 not turn and instead
depart from its lane on a curve while
the lane centering function is operat-
ing.
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

4-5. Using the driving support systems
This mode employs a radar to detect the presence of vehicles up to approx-
imately 100 m (328 ft.) ahead, determines the current vehicle-to-vehicle fol-
lowing distance, and operates to maintain a suitable following distance from
the vehicle ahead. The desired vehicle-to-vehicle distance can also be set
by operating the vehicle-to-vehicle distance switch.
When driving on downhill slopes, the vehicle-to-vehicle distance may become
shorter.
Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver.
Example of deceleration cruising and follow-up cruising
When a preceding vehicle driving slower than the set speed appears
When a vehicle is detected running ahead of you, the system automatically deceler-
ates your vehicle. When a greater reduction in vehicle speed is necessary, the sys-
tem applies the brakes (the stop lights will come on at this time). The system will
respond to changes in the speed of the vehicle ahead in order to maintain the vehi-
cle-to-vehicle distance set by the driver. Approach warning warns you when the sys-
tem cannot decelerate sufficiently to prevent your vehicle from closing in on the
vehicle ahead.
When the turn signal lever is operated and your vehicle moves to an overtaking lane
while driving at 80 km/h (50 mph) or more, the vehicle will accelerate to help to over-
take a passing vehicle.
The system’s identification of what is an overtaking lane may be determined solely
based on the location of the steering wheel in the vehicle (left side driver position

■Conditions under which the vehi-
cle-to-vehicle distance control
mode may not function correctly
In the case of the following conditions,
operate the brake pedal (or accelerator
pedal, depending on the situation) as
necessary.
As the sensor may not be able to cor-
rectly detect vehicles ahead, the system
may not operate properly.
●When the road curves or when the
lanes are narrow
●When steering wheel operation or
your position in the lane is unstable
●When the vehicle ahead of you decel-
erates suddenly
●When driving on a road surrounded by
a structure, such as in a tunnel or on a
bridge
●While the vehicle speed is decreasing

■The system can be operated when
●The engine switch is in ON.
●Toyota parking assist-sensor function
is on.
●The vehicle speed is less than about
10 km/h (6 mph).
●A shift lever other than P is selected.
●Steering wheel is turned approxi- mately 90° or more (Front side sen-
sors, rear side sensors) (if equipped)
■If “Clean Parking Assist Sensor” is displayed on the multi-information display
A sensor may be covered with water drops, ice, snow, dirt, etc. Remove the water drops, ice, snow, dirt, etc., from
the sensor to return the system to nor- mal.
Also, due to ice forming on a sensor at
low temperatures, a warning message may be displayed or the sensor may not
be able to detect an object. Once the ice melts, the system will return to normal.
■Sensor detection information
The following situations may occur
during use.
●The sensors may be able to only
detect objects near the front and rear bumpers.
●Depending on the shape of the object and other factors, the detection dis-tance may shorten, or detection may
be impossible.
●If an object is extremely close to a
sensor, it may not be detected.
WARNING
●The front or rear bumper or a sen- sor receives a strong impact.
●A non-genuine Toyota suspension (lowered suspension, etc.) is
installed.
●Towing eyelets are installed.
●A backlit license plate is installed.
■When using Toyota parking assist-sensor
In the following situations, the system
may not function correctly due to a sensor malfunction, etc. Have the vehicle checked by any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer.
●The Toyota parking assist-sensor operation display flashes or shows continuously, and a beep sounds
when no objects are detected.
●If the area around a sensor collides
with something, or is subjected to strong impact.
●If the bumper or grille collides with something.
●If the display flashes or is displayed continuously and a buzzer does not sound, except when the mute func-
tion has been turned on.
●If a display error occurs, first check
the sensor. If the error occurs even when there is no ice, snow or mud on the sen-
sor, it is likely that the sensor is mal- functioning.
■Notes when washing the vehicle
Do not apply intensive bursts of water or steam to the sensor area.
Doing so may result in the sensor malfunctioning.
●When using a high pressure washer to wash the vehicle, do not spray the sensors directly, as doing
so may cause a sensor to malfunc- tion.
●When using steam to clean the vehicle, do not direct steam too close to the sensors as doing so
may cause a sensor to malfunction.
