Sensors 31

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.

(1) Press “” switches and select from the MID.
(2) Press “

(3) Select “Sensitivity” and then press “

Note: PCS is enabled each time the engine switch is turned to Ignition On. The
system can be disabled/enabled and the alert timing of the system can be changed.
(Alert timing only, brake operation remains the same).

wave radar
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.

ADJUSTING DISTANCE
To change the vehicle-to-vehicle distance

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.

SAFETY & EMERGENCY FEATURES
Star Safety System™
VEHICLE STABILITY CONTROL (VSC)
VSC helps prevent loss of traction during cornering by reducing engine power and
applying brake force to selected wheels.
Toyota’s VSC monitors steering angle and the direction your vehicle is traveling.
When it senses that the front or rear wheels begin to lose traction, VSC reduces
engine power and applies braking to selected wheels. This helps restore traction
and vehicle control.
ANTI-LOCK BRAKE SYSTEM (ABS)
Toyota’s ABS sensors detect which wheels are locking up and limits wheel lockup
by “pulsing” each wheel’s brakes independently. Pulsing releases brake pressure
repeatedly for fractions of a second. This helps the tires attain the traction that
current road conditions will allow, helping you to stay in directional control.
BRAKE ASSIST (BA)
Brake Assist is designed to detect sudden or “panic” braking, and then add braking
pressure to help decrease the vehicle’s stopping distance. When there’s only a split
second to react, Brake Assist can add additional brake pressure more quickly than
just the driver alone can.
ELECTRONIC BRAKE FORCE DISTRIBUTION (EBD)
Toyota’s ABS technology has Electronic Brake-force Distribution (EBD) to help
maintain control and balance when braking. Abrupt stops can cause a vehicle to tilt
forward, reducing the braking power of the rear wheels. EBD responds to sudden
stops by redistributing brake force to enhance the braking effectiveness of all four
wheels. Your vehicle comes standard standard with the Star Safety System
TM, which
combines Anti-lock Braking System (ABS), Brake Assist (BA), Electronic Brake-force
Distribution (EBD), Smart Stop Technology (SST), Traction Control (TRAC) and
Vehicle Stability Control (VSC).

Floor mat installation
TRACTION CONTROL (TRAC)
VSC helps prevent loss of traction during cornering by reducing engine power, and
Traction Control helps maintain traction on loose gravel and wet, icy, or uneven
surfaces by applying brake force to the spinning wheel(s).
Toyota’s TRAC sensors are activated when one of the drive wheels starts to slip.
TRAC limits engine output and applies the brakes to the spinning wheel. This
transfers power to the wheels that still have traction to help keep you on track.
There are two types of Toyota floor mats: carpeted and all-weather. Each vehicle
has model-specific floor mats. Installation is easy.
To keep your floor mat properly positioned, follow these steps:
• Only use Toyota floor mats designed for your specific model.
• Use only one floor mat at a time, using the retaining hooks to keep the mat in
place.
• Install floor mats right side up.
Always align the ¨ marks
