ence:
Driving assist system
WARNING
■Toyota Safety Sense 2.0
The Toyota Safety Sense 2.0 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 condi-
tions.
As there is a limit to the degree of
recognition accuracy and control
performance that this system can
provide, do not overly rely on this
system. The driver is always
responsible for paying attention to
the vehicle’s su rroundings and
driving safely.

WARNING
■Limitations of the pre-colli-
sion system
●The driver is solely responsible
for safe driving. Always drive
safely, taking care to observe
your surroundings.
Do not use the pre-collision sys-
tem instead of normal braking
operations under any circum-
stances. This system will not
prevent collisions or lessen col-
lision damage or injury in every
situation. Do not overly rely on
this system. Failure to do so
may lead to an accident, result-
ing in death or serious injury.
●Although this system is
designed to help avoid a colli-
sion or help reduce the impact
of the collision, its effectiveness
may change according to vari-
ous conditions, therefore the
system may not always be able
to achieve the same level of
performance.
Read the following conditions
carefully. Do not overly rely on
this system and always drive
carefully.
• Conditions under which the sys- tem may operate even if there is
no possibility of a collision:
P. 1 8 2
• Conditions under which the sys- tem may not operate prop-
erly:
P.183
●Do not attempt to test the oper-
ation of the pre-collision system
yourself.
Depending on the objects used
for testing (dummies, card-
board objects imitating detect-
able objects, etc.), the system
may not operate properly, possi-
bly leading to an accident.
■Pre-collision braking
●When the pre-collision braking
function is operating, a large
amount of braking force will be
applied.
●If the vehicle is stopped by the
operation of the pre-collision
braking function, the pre-colli-
sion braking function operation
will be canceled after approxi-
mately 2 seconds. Depress the
brake pedal as necessary.
●The pre-collision braking func-
tion may not operate if certain
operations are performed by the
driver. If the accelerator pedal is
being depressed strongly or the
steering wheel is being turned,
the system may determine that
the driver is taking evasive
action and possibly prevent the
pre-collision braking function
from operating.
●In some situations, while the
pre-collision brak ing function is
operating, operation of the func-
tion may be canceled if the
accelerator pedal is depressed
strongly or the steering wheel is
turned and the system deter-
mines that the driver is taking
evasive action.
●If the brake pedal is being
depressed, the system may
determine that t he driver is tak-
ing evasive action and possibly
delay the operation timing of the
pre-collision braking function.
■When to disable the pre-colli-
sion system
In the following situations, disable
the system, as it may not operate
properly, possibly leading to an
accident resulting in death or seri-
ous injury:
●When the vehicle is being towed

*: If equipped
LTA (Lane Tracing
Assist)*
When driving on highways
and freeways with white
(yellow) lane lines, this
function alerts the driver
when the vehicle might
depart from its lane or
course
* and provides assis-
tance by operating the
steering wheel to keep the
vehicle in its lane or
course
*. Furthermore, the
system provides steering
assistance when dynamic
radar cruise control with
full-speed range is operat-
ing to keep the vehicle in its
lane.
The LTA system recognizes
white (yellow) lane lines or a
course
* using the front cam-
era. 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
WARNING
■Before using LTA system
●Do not rely solely upon the LTA
system. The LTA system does
not automatically drive the vehi-
cle or reduce the amount of
attention that m ust be paid to
the area in front of the vehicle.
The driver must always assume
full responsibilit y for driving
safely by paying careful atten-
tion to the surrounding condi-
tions 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 care-
ful attention may lead to an
accident, resulting in death or
serious injury.
●When not using the LTA system,
use the LTA switch to turn the
system off.
■Situations unsuitable for LTA
system
In the following situations, use the
LTA switch to turn the system off.
Failure to do so may lead to an
accident, resulting in death or
serious injury.

■Before using LDA system
●Do not rely solely upon the LDA
system. The LDA system does
not automatically drive the vehi-
cle 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 atten-
tion to the surrounding condi-
tions 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 care-
ful attention may lead to an
accident, resulting in death or
serious injury.
●When not using the LDA sys-
tem, use the LDA switch to turn
the system off.
■Situations unsuitable for LDA
system
In the following situations, use the
LDA switch to turn the system off.
Failure to do so may lead to an
accident, resulting in death or
serious injury.
●Vehicle is driven on a road sur-
face 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.
●A spare tire, tire chains, etc. are
equipped.
●When the tires have been
excessively worn, or when the
tire inflation p ressure is low.
●When tires of a size other than
specified are installed.
●Vehicle is driven in traffic lanes
other than that highways and
freeways.
●During emergency towing.
■Preventing LDA system mal-
functions and operations per-
formed by mistake
●Do not modify the headlights or
place stickers, etc. on the sur-
face of the lights.
●Do not modify the suspension
etc. If the suspension etc. needs
to be replaced, contact your
Toyota dealer.
●Do not install or place anything
on the hood or grille. Also, do
not install a gr ille guard (bull
bars, kangaroo bar, etc.).
●If your windshield needs
repairs, contact your Toyota
dealer.
■Conditions in which functions
may not operate properly
In the following situations, the
functions may not operate prop-
erly and the vehicle may depart
from its lane. Drive safely by
always paying careful attention to
your surroundings and operate
the steering wheel to correct the
path of the vehicle without relying
solely on the functions.

driver is responsible for check-
ing the set speed.
●Even when the system is func-
tioning normally, the condition of
the preceding vehicle as
detected by the system may dif-
fer from the condition observed
by the driver. Therefore, the
driver must always remain alert,
assess the danger of each situ-
ation and drive safely. Relying
solely on this system or assum-
ing 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

This mode employs a radar to detect the presence of vehicles up to
approximately 328 ft. (100 m) ahead, determines the current veh i-
cle-to-vehicle following distance, and operates to maintain a s uitable
following distance from the vehicle ahead. The desired vehi-
cle-to-vehicle distance can also be set by operating the vehi-
cle-to-vehicle distance switch.
When driving on downhill slopes, t he 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 crui sing and follow-up cruising
When a preceding vehicle driving slower than the set speed
appears
When a vehicle is detected runni ng ahead of you, the system automatically
decelerates your vehicle. When a greater reduction in vehicle s peed is nec-
essary, 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 st ops, your vehicle will also stop (vehicle is
stopped by system control). Afte r 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 pe rformed, system
control continues to keep your vehicle stopped.

shown correspond to a vehicle
speed of 50 mph (80 km/h).
Vehicle-to-vehicle distance
increases/decreases in accor-
dance with vehicle speed. When
the vehicle is stopped by system
control, the vehicle stops at a
certain vehicle-to-vehicle dis-
tance depending on the situa-
tion.
After the vehicle ahead of you
starts off, press the “+RES”
switch.
Your vehicle will also resume
follow-up cruising if the acceler-
ator pedal is depressed after the
vehicle ahead of you starts off.1
Pressing the cancel switch
cancels the speed control.
The speed control is also canceled
when the brake pedal is depressed.
(When the vehicle has been
stopped by system control,
depressing the br ake pedal does
not cancel the setting.)

■Warning messages and buzzers
for dynamic radar cruise con-
trol with full-speed range
Warning messages and buzzers are
used to indicate a system malfunc-
tion or to inform the driver of the
need for caution while driving. If a
warning message is shown on the
multi-information display, read the
message and follow the instructions.
(  P.172, 477)
■When the sensor may not be
correctly detecting the vehicle
ahead
In the case of the following and
depending on the conditions, oper-
ate the brake pedal when decelera-
tion of the system is insufficient or
operate the accelerator pedal when
acceleration is required.
As the sensor may not be able to
correctly detect these types of vehi-
cles, the approach warning
(  P.210) may not be activated.
●Vehicles that cut in suddenly
●Vehicles traveling at low speeds
●Vehicles that are not moving in the
same lane
●Vehicles with small rear ends
(trailers with no load on board,

●Assisting the driver to measure
following distance
The dynamic radar cruise control
is only intended to help the driver
in determining the following dis-
tance between the driver’s own
vehicle and a desi gnated vehicle
traveling ahead. It is not a mecha-
nism that allows careless or inat-
tentive driving, and it is not a
system that can a ssist the driver
in low-visibility conditions.
It is still necessa ry for driver to
pay close attenti on to the vehi-
cle’s surroundings.
