OVERVIEW FEATURES & OPERATIONS TOYOTA SAFETY SENSE SAFETY & EMERGENCY FEATURES
Quick overview-Toyota Safety Sense™ P (TSS-P)
Sensors
TSS-P combines an in-vehicle camera mounted in front of the inside rear view mirror
and a millimeter-wave radar mounted in the front grill. These sensors support the
driver assist systems.

TOYOTA SAFETY SENSE™
Toyota Safety Sense™ P (TSS-P) is a set of active safety technologies designed
to help mitigate or prevent collisions across a wide range of traffic situations, in
certain conditions. TSS-P is designed to help support the driver’s awareness,
decision making and vehicle operation contributing to a safe driving experience.

The Pre-Collision System uses a radar sensor and camera sensor to help detect a
vehicle or pedestrian in front of your vehicle.
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. This system will not
prevent collisions or lessen collision damage or injury in every situation. Do not use
PCS instead of normal braking operations under any circumstances. Do not attempt
to test the operation of the pre-collision system yourself, as the system may not
operate or engage, possibly leading to an accident. In some situations, such as
when driving in inclement weather such as heavy rain, fog, snow or a sandstorm or
while driving on a curve and for a few seconds after driving on a curve, a vehicle
may not be detected by the radar and camera sensors, preventing the system from
operating or engaging properly.
Refer to a Toyota Owner’s Manual for a list of additional situations in which the
system may not operate properly.
Refer to a Toyota Owner’s Manual for additional information on PCS w/PD operation,
settings adjustments, limitations, and precautions before attempting to use it. Pre-Collision Warning
When the system determines that the possibility of a frontal collision is high, a
buzzer will sound and a warning message will be displayed on the Multi-Information
Display (MID) to urge the driver to take evasive action.
Pre-Collision Brake Assist
If the driver notices the hazard and brakes, the system may provide additional
braking force using Brake Assist. This system may prime the brakes and may apply
greater braking force in relation to how strongly the brake pedal is depressed.
Pre-Collision Braking
If the driver does not brake in a set time and the system determines that the
possibility of a frontal collision with a preceding vehicle is extremely high, the
system may automatically apply the brakes, reducing speed in order to help the
driver reduce the impact and in certain cases avoid the collision.

As part of the Pre-Collision System, this function is also designed to first provide an
alert and then automatic braking if needed.In certain conditions, the PCS system included with the TSS-P package may also
help to detect a pedestrian in front of your vehicle. With Toyota Safety Sense™ P,
PCS uses an in-vehicle camera and front-grill mounted millimeter-wave radar to
help detect a pedestrian in front of your vehicle in certain conditions. The in-vehicle
camera of PCS detects a potential pedestrian based on size, profile, and motion of
the detected pedestrian. However, a pedestrian may not be detected depending
on the conditions, including the surrounding brightness and the motion, posture,
size, and angle of the potential detected pedestrian, preventing the system from
operating or engaging. Refer to a Toyota Owner’s Manual for additional information.

DISABLING THE PRE-COLLISION SYSTEM (PCS)
LDA in TSS-P uses an in-vehicle camera designed to detect visible white and
yellow lane markers in front of the vehicle and the vehicle’s position on the road.
If the system determines that the vehicle is starting to unintentionally deviate from
its lane, the system alerts the driver with an audio and visual alert. When the alerts
occur, the driver must check the surrounding road situation and carefully operate
the steering wheel to move the vehicle back to the center part of their lane.
LDA is designed to function at speeds of approximately 32 MPH or higher on
relatively straight roadways.
In addition to the alert function, LDA w/SA also features a steering assist
function. When enabled, if the system determines that the vehicle is on a path
to unintentionally depart from its lane, the system may provide small corrective
steering inputs to the steering wheel for a short period of time to help keep the
vehicle in its lane.

TURNING THE LDA SYSTEM ON/OFF
Press the LDA switch to turn the LDA system on. Depress again to turn it off.
Note: The system will continue in the last state it was in (ON or OFF) when the engine is
started again.
Refer to a Toyota Owner’s Manual for additional information on LDA operation,
settings adjustments, limitations, and precautions before attempting to use it.

The LDA function
displays when the Multi-Information Display (MID) is
switched to the driving assist system information screen.
(1) The system displays solid white lines on the LDA indicator when visible lane
markers on the road are detected. A side flashes orange to alert the driver when the
vehicle deviates from its lane.
(2) The system displays outlines on the LDA indicator when lane markers on the
road are not detected or the function is temporarily cancelled.
Note: When operation conditions are no longer met, a function may be temporarily
canceled. However, when the operation conditions are met again, operation of the
function is automatically restored. For example, LDA may not function on the side(s)
where white/yellow lines are not detectable.

Push the “
” button to cycle
through the settings, which will
change progressively. Preceding vehicle mark
This mode employs a radar sensor 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 following distance from the
vehicle ahead.
Note: Vehicle-to-vehicle distance will close in when traveling on long downhill slopes.
LONG
(default setting)MIDDLE SHORT
(1) Constant speed cruising when there are no vehicles ahead
The vehicle travels at the speed set by the driver. The desired vehicle-to-
vehicle distance can also be set by operating the vehicle-to-vehicle distance
control.
(2) 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 brake 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. A warning
tone warns you when the system cannot decelerate sufficiently to prevent your
vehicle from closing in on the vehicle ahead.
(3) 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.
Note: When your vehicle is too close to a vehicle ahead, and sufficient automatic
deceleration via the cruise control is not possible, the display will flash and the buzzer
will sound to alert the driver. An example of this would be if another driver cuts in
front of you while you are following a vehicle. Depress the brake pedal to ensure an
appropriate vehicle-to-vehicle distance.
