While driving on a road with clear white (yellow) lane lines, the LTA
system warns the driver if the vehicle may deviate from the current
lane or course

*

, and also can slightly operate the steering wheel to

help avoid deviation from the lane or course

*

. Also, while the dynamic

radar cruise control with full-speed range is operating, this system will
operate the steering wheel to maintain the vehicle’s lane position.
The LTA system recognizes white
(yellow) lane lines or a course

*

using the front camera. Addition-
ally, it detects preceding vehicles
using the front camera and radar.

Summary of functions

WARNING

■

Before using LTA system

●

Do not rely solely upon the LTA system. The LTA system does not auto-
matically drive the vehicle or reduce the amount of attention that must be
paid to the area in front of the vehicle. The driver must always assume full
responsibility for driving safely by paying careful attention to the surround-
ing conditions and operating the steering wheel to correct the path of the
vehicle. Also, the driver must take adequate breaks when fatigued, such
as from driving for a long period of time.

●

Failure to perform appropriate driving operations and pay careful attention
may lead to an accident, resulting in death or serious injury.

WARNING

■

Before using dynamic radar cruise control with full-speed range

●

Driving safely is the sole responsibility of the driver. Do not rely solely on
the system, and drive safely by always paying careful attention to your sur-
roundings.

●

The dynamic radar cruise control with full-speed range provides driving
assistance to reduce the driver's burden. However, there are limitations to
the assistance provided.
Read the following conditions carefully. Do not overly rely on this system
and always drive carefully.
• When the sensor may not be correctly detecting the vehicle ahead:



P. 309

• Conditions under which the vehicle-to-vehicle distance control mode

may not function correctly:



P. 310

●

Set the speed appropriately depending on the speed limit, traffic flow, road
conditions, weather conditions, etc. The driver is responsible for checking
the set speed.

●

Even when the system is functioning normally, the condition of the preced-
ing vehicle as detected by the system may differ from the condition
observed by the driver. Therefore, the driver must always remain alert,
assess the danger of each situation and drive safely. Relying solely on this
system or assuming the system ensures safety while driving can lead to
an accident, resulting in death or serious injury.

●

Switch the dynamic radar cruise control with full-speed range setting to off,
using the cruise control main switch when not in use.

WARNING

■

Cautions regarding the driving assist systems

Observe the following precautions, as there are limitations to the assistance
provided by the system.
Failure to do so may cause an accident resulting in death or serious injury.

●

Assisting the driver to measure following distance
The dynamic radar cruise control with full-speed range is only intended to
help the driver in determining the following distance between the driver’s
own vehicle and a designated vehicle traveling ahead. It is not a mecha-
nism 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 driver to pay close attention to the vehicle’s sur-
roundings.

●

Assisting the driver to judge proper following distance
The dynamic radar cruise control with full-speed range determines
whether the following distance between the driver’s own vehicle and a
designated vehicle traveling ahead is within a set range. It is not capable
of making any other type of judgement. Therefore, it is absolutely neces-
sary for the driver to remain vigilant and to determine whether or not there
is a possibility of danger in any given situation.

●

Assisting the driver to operate the vehicle
The dynamic radar cruise control with full-speed range does not include
functions which will prevent or avoid collisions with vehicles ahead of your
vehicle. Therefore, if there is ever any possibility of danger, the driver must
take immediate and direct control of the vehicle and act appropriately in
order to ensure the safety of all involved.

WARNING

■

Situations unsuitable for dynamic radar cruise control with full-speed
range

Do not use dynamic radar cruise control with full-speed range in any of the
following situations.
Doing so may result in inappropriate speed control and could cause an acci-
dent resulting in death or serious injury.

●

Roads where there are pedestrians, cyclists, etc.

●

In heavy traffic

●

On roads with sharp bends

●

On winding roads

●

On slippery roads, such as those covered with rain, ice or snow

●

On steep downhills, or where there are sudden changes between sharp up
and down gradients
Vehicle speed may exceed the set speed when driving down a steep hill.

●

At entrances to freeways and highways

●

When weather conditions are bad enough that they may prevent the sen-
sors from detecting correctly (fog, snow, sandstorm, heavy rain, etc.)

●

When there is rain, snow, etc. on the front surface of the radar or front
camera

●

In traffic conditions that require frequent repeated acceleration and decel-
eration

●

During emergency towing

●

When an approach warning buzzer is heard often

This mode employs a radar to detect the presence of vehicles up to
approximately 328 ft. (100 m) ahead, determines the current vehicle-
to-vehicle following distance, and operates to maintain a suitable fol-
lowing distance from the vehicle ahead. The desired vehicle-to-vehi-
cle 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
decelerates your vehicle. When a greater reduction in vehicle speed is
necessary, the system 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 vehicle-to-vehicle distance set by the driver.
Approach warning warns you when the system cannot decelerate suffi-
ciently to prevent your vehicle from closing in on the vehicle ahead.
When the vehicle ahead of you stops, your vehicle will also stop (vehicle is
stopped by system control). After the vehicle ahead starts off, pressing the
“+ RES” switch or depressing the accelerator pedal (start-off operation) will
resume follow-up cruising. If the start-off operation is not performed, sys-
tem control continues to keep your vehicle stopped.

4-5. Using the driving support systems

When the turn signal lever is operated and your vehicle moves to an over-
taking lane while driving at 50 mph (80 km/h) or more, the vehicle will
accelerate to help to overtake a passing vehicle.
The system’s identification of what is an overtaking lane may be deter-
mined solely based on the location of the steering wheel in the vehicle (left
side driver position versus right side driver position.) If the vehicle is driven
to a region where the overtaking lane is on a different side from where the
vehicle is normally driven, the vehicle may accelerate when the turn signal
lever is operated in the opposite direction to the overtaking lane (e.g., if the
driver normally operates the vehicle in a region where the overtaking lane
is to the right but then drives to a region where the overtaking lane is to the
left, the vehicle may accelerate when the right turn signal is activated).

Example of acceleration
When there are no longer any preceding vehicles driving slower
than the set speed

The system accelerates until the set speed is reached. The system then
returns to constant speed cruising.

Press the cruise control main
switch to activate the cruise
control.

Dynamic radar cruise control indi-
cator will come on and a message
will be displayed on the multi-infor-
mation display.
Press the switch again to deacti-
vate the cruise control.
If the cruise control main switch is pressed and held for 1.5 seconds or
more, the system turns on in constant speed control mode. (

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

■

Secondary Collision Brake operating conditions

The system operates when the SRS airbag sensor detects a collision while
the vehicle is in motion.
However, the system does not operate in any of the following situations.

●

The vehicle speed is below 6 mph (10 km/h)

●

Components are damaged

■

Secondary Collision Brake automatic cancellation

The Secondary Collision Brake is automatically canceled in the following situ-
ations:

●

The vehicle speed drops below approximately 6 mph (10 km/h)

●

A certain amount of time elapses during operation

●

The accelerator pedal is depressed a large amount

■

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 EPS system should return to normal within 10 minutes.

The limits of tire gripping performance have been exceeded (such as
excessively worn tires on a snow covered road).

●

The vehicle hydroplanes while driving at high speed on wet or slick roads.

■

Stopping distance when the ABS is operating may exceed that of nor-
mal conditions

The ABS is not designed to shorten the vehicle’s stopping distance. Always
maintain a safe distance from the vehicle in front of you, especially in the
following situations:

●

When driving on dirt, gravel or snow-covered roads

●

When driving with tire chains

●

When driving over bumps on the road

●

When driving over roads with potholes or uneven surfaces

■

TRAC/VSC may not operate effectively when

Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the TRAC/VSC system is operating.
Drive the vehicle carefully in conditions where stability and power may be
lost.

■

Hill- start assist control does not operate effectively when

●

Do not overly rely on hill-start assist control. Hill-start assist control may
not operate effectively on steep inclines and roads covered with 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, as doing so may
lead to an accident.

■

When the TRAC/ABS/VSC is activated

The slip indicator light flashes. Always drive carefully. Reckless driving may
cause an accident. Exercise particular care when the indicator light flashes.

■

When the TRAC/VSC systems are turned off

Be especially careful and drive at a speed appropriate to the road condi-
tions. As these are the systems to help ensure vehicle stability and driving
force, do not turn the TRAC/VSC systems off unless necessary.

■

Secondary Collision Brake

Do not overly rely solely upon the Secondary Collision Brake. This system
is designed to help reduce the possibility of further damage due to a sec-
ondary collision, however, that effect changes according to various condi-
tions. Overly relying on the system may result in death or serious injury.

Replacing tires

Make sure that all tires are of the specified size, brand, tread pattern and
total load capacity. In addition, make sure that the tires are inflated to the
recommended tire inflation pressure level.
The ABS, TRAC and VSC systems will not function correctly if different tires
are installed on the vehicle.
Contact your Toyota dealer for further information when replacing tires or
wheels.

The BSM function uses radar sensors to detect the following vehicles
traveling in an adjacent lane in the area that is usually not reflected in
the outside rear view mirror (the blind spot), and advises the driver of
the presence of such vehicles via the indicators on the outside rear
view mirrors.

WARNING

■

Cautions regarding the use of the system

The driver is solely responsible for safe driving. Always drive safely, taking
care to observe your surroundings.
The BSM function is a supplementary function which alerts the driver that a
vehicle is present in the blind spot. Do not overly rely on the BSM function.
The function cannot judge if it is safe to change lanes, therefore over reli-
ance could cause an accident resulting in death or serious injury.
According to conditions, the system may not function correctly. Therefore
the driver’s own visual confirmation of safety is necessary.

Buzzer operation and distance to an object

A buzzer sounds when the sensors are operating.

●

The buzzer sounds faster as the vehicle approaches an object.
When the vehicle comes within the following distance of the
object, the buzzer sounds continuously: Approximately 1.2 ft. (35
cm).

●

When 2 or more objects are detected simultaneously, the buzzer
system responds to the nearest object. If one or both come within
the above distances, the beep will repeat a long tone, followed by
fast beeps.

●

Automatic buzzer mute function
After a buzzer begins sounding, if the distance between the vehi-
cle and the detected object does not become shorter, the buzzer
will be muted automatically.
(However, if the distance between the vehicle and object is 1.0 ft.
(30 cm) or less, this function will not operate.)

Approximately 3.3 ft. (100 cm)
Approximately 4.9 ft. (150 cm)

Sensor detection information

●

The sensor’s detection areas are limited to the areas around the vehicle’s
bumper.

●

Depending on the shape of the object and other factors, the detection dis-
tance may shorten, or detection may be impossible.

●

Objects may not be detected if they are too close to the sensor.

●

There will be a short delay between object detection and display. Even at
slow speeds, there is a possibility that the object will come within the sen-
sor’s detection areas before the display is shown and the buzzer sounds.

●

It might be difficult to hear beeps due to the volume of audio system or air
flow noise of the air conditioning system.

■

If “Parking Assist Unavailable Clean Parking Assist Sensor” is displayed
on the multi-information display

A sensor may be dirty or covered with snow or ice. In such cases, if it is
removed from the sensor, the system should return to normal.
Also, due to the sensor being frozen at low temperatures, a malfunction dis-
play may appear or an object may not be detected. If the sensor thaws out,
the system should return to normal.

■

If “Parking Assist Unavailable” is displayed on the multi-information dis-
play

Water may be continuously flowing over the sensor surface, such as in a
heavy rain. When the system determines that it is normal, the system will

Sensors

Certain vehicle conditions and the surrounding environment may affect the
ability of a sensor to correctly detect an object. Particular instances where
this may occur are listed below.

●

There is dirt, snow or ice on the sensor. (Wiping the sensors will resolve
this problem.)

●

The sensor is frozen. (Thawing the area will resolve this problem.)
In especially cold weather, if a sensor is frozen the screen may show an
abnormal display, or objects may not be detected.

●

The sensor is covered in any way.

●

The vehicle is leaning considerably to one side.

●

On an extremely bumpy road, on an incline, on gravel, or on grass.

●

The vicinity of the vehicle is noisy due to vehicle horns, motorcycle
engines, air brakes of large vehicles, or other loud noises producing ultra-
sonic waves.

●

There is another vehicle equipped with parking assist sensors in the vicin-
ity.

●

The sensor is coated with a sheet of spray or heavy rain.

●

The sensor is drenched with water on a flooded road.

●

The vehicle is equipped with a fender pole, wireless antenna or fog lights.

●

The bumper or sensor receives a strong impact.

●

The vehicle is approaching a tall or curved curb.

●

The detection range is reduced due to an object such as a sign.

●

In harsh sunlight or intense cold weather.

●

The area directly under the bumpers is not detected.

●

If objects draw too close to the sensor.

●

A non-genuine Toyota suspension (lowered suspension, etc.) is installed.

●

A backlit license plate is installed.

In addition to the examples above, there are instances in which, because of
their shape, signs and other objects may be judged by a sensor to be closer
than they are.
