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.

2304-5. Using the driving support systems
●When you turn right/left,
pedestrian is detected in the
forward direction and esti-
mated to enter your vehicle’s
path (bicyclists are not
detected.)
■Suspension control (if equipped)
When the system determines that the possibility of a frontal colli-
sion is high, the Adaptive Variable Suspension System ( P. 329)
will control the damping force of the shock absorbers to help main-
tain an appropriate vehicle posture.
WARNING
■ Limitations of the pre-collision system
● The driver is solely responsible for safe driving. Always drive safely, taking
care to observe your surroundings.
Do not use the pre-collision system instead of normal braking o perations
under any circumstances. This system will not prevent collision s or lessen
collision damage or injury in every situation. Do not overly re ly on this sys-
tem. Failure to do so may lead to an accident, resulting in dea th or serious
injury.
● Although this system is designed to help avoid a collision or h elp 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 system may operate even if there is no pos- sibility of a collision: P. 237
• Conditions under which the system may not operate properly: P. 239
● Do not attempt to test the operation of the pre-collision syste m yourself.
Depending on the objects used for testing (dummies, cardboard o bjects
imitating detectable objects, etc.), the system may not operate properly,
possibly leading to an accident.

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.

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 li mitations 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 ahe ad:
P. 277
• Conditions under which the vehicle-to-vehicle distance control mode
may not function correctly: P. 278
● 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 s olely 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 s etting to off,
using the cruise control main switch when not in use.

Driving
This mode employs a radar to detect the presence of vehicles up to
approximately 328 ft. (100 m) ahead, determines the current veh icle-
to-vehicle following distance, and operates to maintain a suita ble fol-
lowing distance from the vehicle ahead. The desired vehicle-to- vehi-
cle distance can also be set by operating the vehicle-to-vehicl e
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 crui sing 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 s peed 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 su ffi-
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 o peration) will
resume follow-up cruising. If the start-off operation is not pe rformed, sys-
tem control continues to keep your vehicle stopped.

■Automatic cancelation of c onstant speed control mode
Constant speed control mode is automatically canceled in the following situa-
tions:
● Actual vehicle speed is more than approximately 10 mph (16 km/h ) below
the set vehicle speed.
● Actual vehicle speed falls below approximately 20 mph (30 km/h) .
● VSC is activated.
● TRAC is activated for a period of time.
● When the VSC or TRAC system is turned off.
● When the brake control or output restriction control of a driving support sys-
tem operates. (For example: Pre -Collision System, Drive-Start Control)
If constant speed control mode is automatically canceled for any reasons
other than the above, there may be a malfunction in the system. Contact your
Toyota dealer.
■ Situations in which the curve speed reduction function may not operate
In situations such as the following, the curve speed reduction function may
not operate:
● When the vehicle is being driven around a gentle curve
● When the accelerator pedal is being depressed
● When the vehicle is being driven around an extremely short curve
■ Brake operation
A brake operation sound may be heard and the brake pedal response may
change, but these are not malfunctions.
■ Warning messages and buzzers for d ynamic radar cruise control with
full-speed range
Warning messages and buzzers are used to indicate a system malfunction 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. 226, 465)

2824-5. Using the driving support systems
WARNING
■Handling the radar sensor
One Blind Spot Monitor sensor is installed inside the left and right side of
the vehicle rear bumper respectively. Observe the following to ensure the
Blind Spot Monitor can function correctly.
If the warning message does not disappear, have the vehicle inspected
by your Toyota dealer
● Do not subject a sensor or its surrounding area on the rear bumper to a
strong impact.
If a sensor is moved even slightly off position, the system may malfunction
and vehicles may not be detected correctly.
In the following situations, have your vehicle inspected by your Toyota
dealer.
• A sensor or its surrounding area is subject to a strong impact .
• If the surrounding area of a sensor is scratched or dented, or part of them has become disconnected.
● Do not disassemble the sensor.
● Do not attach accessories or stickers to the sensor or surrounding area on
the bumper.
● Do not modify the sensor or surrounding area on the bumper.
● Do not paint the rear bumper any color other than an official Toyota color.
●Keep the sensor and its surrounding
area on the bumper clean at all times. If
a sensor or its surrounding area on the
rear bumper is dirty or covered with
snow, the Blind Spot Monitor may not
operate and a warning message will be
displayed. ( P. 280)
In this situation, clear off the dirt or
snow and drive the vehicle with the
operation conditions of the BSM func-
tion satisfied for approximately 60 min-
utes.
