Toyota Safety Sense 2.5+
The Toyota Safety Sense 2.5+ c onsists of the following drive
assist systems and contributes t o a safe and comfortable driv-
ing experience:
Driving assist system
WARNING
■ Toyota Safety Sense 2.5+
The Toyota Safety Sense 2.5+ 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 recognition 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 surround-
ings and driving safely.

■Pre-collision braking
If the system determines that the possibility of a frontal collision is
extremely high, the brakes are automatically applied to help avoid
the collision or reduce th e impact of the collision.
■Emergency steering assist
If the system determines that the possibility of a frontal collision is
high and that there is sufficient space for the vehicle to be s teered
into within its lane, and the dr iver has begun evasive maneuver or
steering, emergency steering assist will assist the steering move-
ments to help enhance the vehicle stability and for lane depart ure
prevention.
During operation, the indicator
will illuminate in green.
■Intersection right/left turn assistance
If the system determines that t here is a high possibility of a collision
in the following situations, it will assist with Pre-collision warning
and, if necessary Pre-collision braking.
Depending on the configuration of the intersection, it may not be
possible to support.
● When you turn right/left at an
intersection and cross the
path of an oncoming vehicle

WARNING
■Pre-collision braking
● When the pre-collision braking function is operating, a large a mount of
braking force will be applied.
● If the vehicle is stopped by the operation of the pre-collision braking func-
tion, the pre-collision braking function operation will be canceled after
approximately 2 seconds. Depress the brake pedal as necessary.
● The pre-collision braking function 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-colli-
sion braking function from operating.
● In some situations, while the pre-collision braking function is operating,
operation of the function may be canceled if the accelerator pedal is
depressed strongly or the steering wheel is turned and the syst em deter-
mines that the driver is taking evasive action.
● If the brake pedal is being depressed, the system may determine that the
driver is taking evasive action and possibly delay the operation timing of
the pre-collision braking function.
■ Emergency steering assist
● As emergency steering assist operation will be canceled when th e system
determines that lane departure prevention function has been completed.
● Emergency steering assist may not operate or may be cancel in the follow-
ing cases as the system may determine the driver is taking acti ons.
• If the accelerator pedal is being depressed strongly, the steering wheel is being operated sharply, the brake pedal is being depressed o r the
turn signal lever is being operated. In this case, the system m ay deter-
mine that the driver is taking evasive action and the emergency steering
assist may not operate.
• In some situations, while the emergency steering assist is ope rating,
operation of the function may be canceled if the accelerator pe dal is
depressed strongly, the steeri ng wheel is operated sharply or t he brake
pedal is being depressed and the system determines that the dri ver is
taking evasive action.
• When the emergency steering assist is operating, if the steering wheel
is held firmly or is operated in the opposite direction to that which the
system is generating torque, the function may be canceled.

• If the wheels are misaligned
• If a wiper blade is blocking the front camera
• The vehicle is being driven at extremely high speeds
• When driving on a hill
• If the radar sensor or front camera is misaligned
• When driving in a traffic lane separated by more than one lane where
oncoming vehicles are driving while making a right/left turn
● In addition to the above, in some situations, such as the follo wing, the emer-
gency steering assist may not operate.
• When the white (yellow) lane lines are difficult to see, such as when they
are faint, diverging/merging, or a shadow is cast upon them
• When the lane is wider or narrower than normal
• When there is a light and dark pattern on the road surface, su ch as due to
road repairs
• When the target is too close
• When there is insufficient safe or unobstructed space for the vehicle to be
steered into
• If oncoming vehicle is present
• If VSC function is operating • If the front of the vehicle is raised or lowered
• When largely out of place with the opposite facing targeted oncoming
vehicle during a right/left turn
• While making a right/left turn, when a pedestrian approaches from behind
or side of your vehicle

Driving
While driving on a road with clear white (yellow) lane lines, the LTA
system warns the driver if the vehicle may deviate from the cur rent
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 s ystem will
operate the steering wheel to maintain the vehicle’s lane posit ion.
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.
*: 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 system. The LTA system does not auto-
matically drive the vehicle or reduce the amount of attention t hat 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.

◆Steering assist function
When the system determines
that the vehicle might depart
from its lane or course
*, the
system provides assistance as
necessary by operating the
steering wheel in small
amounts for a short period of
time to keep the vehicle in its
lane.
Vehicle with BSM: When the
system determines that the
vehicle might depart from its
lane and that the possibility of a
collision with an overtaking vehi-
cle in the adjacent lane is high,
the steering assist function will
operate even if the turn signals
are operating.
*: Boundary between asphalt and the side of the road, such as gra ss, soil,
or a curb

2684-5. Using the driving support systems
◆Vehicle sway warning function
When the vehicle is swaying
within a lane, the warning
buzzer will sound and a mes-
sage will be displayed on the
multi-information display to alert
the driver.
◆Lane centering function
This function is linked with
dynamic radar cruise control
with full-speed range and pro-
vides the required assistance
by operating the steering wheel
to keep the vehicle in its current
lane.
When dynamic radar cruise con-
trol with full-speed range is not
operating, the lane centering
function 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 func-
tion will operate to help follow a
preceding vehicle by monitoring
the position of the preceding
vehicle.
