WARNING
■Toyota Safety Sense
The Toyota Safety Sense is designed to operate under the assumption that the driver will drive safely, and is
designed to help reduce the impact to the occupants and the vehicle in the case of a collision or assist the driver
in normal driving conditions. As there is a limit to the degree of rec-ognition accuracy and control perfor-
mance that this system can provide, do not overly rely on this system. The driver is always responsible for paying
attention to the vehicle’s surroundings and driving safely.
Sensors
WARNING
■To avoid malfunction of the radar sensor
Observe the following precautions.
Otherwise, the radar sensor may not operate properly, possibly leading to an accident resulting in death or seri-
ous injury.

4-5. Using the driving support systems
*: If equipped
While driving on a road with clear
white (yellow) lane lines, the LTA
system warns the driver if the vehi-
cle 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 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. Additionally,
it detects preceding vehicles using
the front camera and radar.
*: Boundary between asphalt and the
side of the road, such as grass, soil,
or a curb
LTA (Lane Tracing
Assist)*
Summary of functions
WARNING
■Before using LTA system
●Do not rely solely upon the LTA sys-
tem. The LTA system does not automatically 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 surrounding conditions and operating the steering wheel to cor-
rect 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 driv-
ing operations and pay careful attention may lead to an accident, resulting in death or serious injury.
■Situations unsuitable for LTA system
In the following situations, use the LTA switch to turn the system off. Fail-ure to do so may lead to an accident,
resulting in death or serious injury.
●Vehicle is driven on a road surface
which is slippery due to rainy weather, fallen snow, freezing, etc.
●Vehicle is driven on a snow-cov-ered road.
●White (yellow) lines are difficult to see due to rain, snow, fog, dust, etc.
●Vehicle is driven in a temporary lane or restricted lane due to con-
struction work.
●Vehicle is driven in a construction
zone.
●A spare tire, tire chains, etc., are
equipped.
●When the tires have been exces-
sively worn, or when the tire infla- tion pressure is low.

■Vehicle sway warning function
When the vehicle is swaying within
a lane, the warning buzzer will
sound and a message will be dis-
played on the multi-information dis-
play to alert the driver.
■Lane centering function
This function is linked with dynamic
radar cruise control and provides
the required assistance by operat-
ing the steering wheel to keep the
vehicle in its current lane.
When dynamic radar cruise control is
not operating, the lane centering func-
tion does not operate.
In situations where the white (yellow)
lane lines are difficult to see or are not
visible, such as when in a traffic jam,
this function will operate to help follow a
preceding vehicle by monitoring the
position of the preceding vehicle.

Driving
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

orange, follow the appropriate trouble-
shooting procedure. Also, if a different
warning message is displayed, follow
the instructions displayed on the screen.

erly. Have the vehicle inspected by any
authorized Toyota retailer or Toyota
authorized repairer, or any reliable
repairer.
●“LTA Unavailable”
The system is temporarily canceled due
to a malfunction in a sensor other than
the front camera. Turn the LTA system
off, wait for a little while, and then turn

The function cannot be used as the
vehicle speed exceeds the LTA opera-
tion range. Drive slower.
■Customization
Function settings can be changed. (Cus-
tomizable features: →P.361)
*: If equipped
In vehicle-to-vehicle distance con-
trol mode, the vehicle automati-
cally accelerates and decelerates
to match the speed changes of the
preceding vehicle even if the accel-
erator pedal is not depressed. In
constant speed control mode, the
vehicle runs at a fixed speed.
Use the dynamic radar cruise con-
trol on freeways and highways.

WARNING
■Before using dynamic radar cruise control
●Driving safely is the sole responsi-bility of the driver. Do not rely solely on the system, and drive safely by
always paying careful attention to your surroundings.
●The dynamic radar cruise control provides driving assistance to
reduce the driver’s burden. How- ever, there are limitations to the assistance provided.
Read the following conditions care-
fully. Do not overly rely on this system
and always drive carefully.
• When the sensor may not be cor- rectly detecting the vehicle ahead: → P. 1 9 0
• Conditions under which the vehicle- to-vehicle distance control mode may not function correctly: →P. 1 9 1
●Set the speed appropriately depending on the speed limit, traffic flow, road conditions, weather con-
ditions, etc. The driver is responsi- ble for checking the set speed.
●Even when the system is function-ing normally, the condition of the preceding vehicle as detected by
the system may differ from the con- dition 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 seri-
ous injury.
●Switch the dynamic radar cruise
control setting to off, using the cruise control main switch when not in use.
■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 fol-lowing distance
The dynamic radar cruise control 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 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 driver to pay
close attention to the vehicle’s sur-
roundings.

Driving
WARNING
●Assisting the driver to judge proper following distance
The dynamic radar cruise control
determines whether the following dis-
tance between the driver’s own vehi-
cle 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
necessary for the driver to remain vig-
ilant 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
does not include functions which will
prevent or avoid collisions with vehi-
cles ahead of your vehicle. Therefore,
if there is ever any possibility of dan-
ger, the driver must take immediate
and direct control of the vehicle and
act appropriately in order to ensure
the safety of all involved.
■Situations unsuitable for dynamic radar cruise control
Do not use dynamic radar cruise con-
trol in any of the following situations. Doing so may result in inappropriate speed control and could cause an
accident 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 high-ways
●When weather conditions are bad enough that they may prevent the sensors 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 fre-quent repeated acceleration and
deceleration
●During emergency towing
●When an approach warning buzzer is heard often
