34 When a collision may occur with an obstacle while parking or traveling at low
speeds, when the vehicle suddenly moves forward due to mistaken accelerator
pedal operation, or when the vehicle moves due to the wrong shift position being
selected, the sensors detect obstacles to the front or rear in the traveling direction
of the vehicle, and the system operates to lessen impact with obstacles such as
walls, and reduce resulting damage.

outside rear view side mirror indicators.
Rear Cross Traffic Alert function:
While in reverse, when a vehicle approaching from the right or left rear of the
vehicle is detected, the outside rear view mirror indicators will flash. Also, the RCTA

TOYOTA SAFETY SENSE™
Sensors
TSS 2.0 combines a forward-facing camera mounted in front of the inside rear view
mirror and a grille-mounted radar mounted in the front grille. These sensors support the
driver assist systems.
The Pre-Collision System uses a grille-mounted radar and forward-facing camera to
help detect a vehicle or pedestrian or bicyclist 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 or pedestrian or
bicyclist may not be detected by the grille-mounted radar and forward-facing camera,
preventing the system from operating or engaging properly.
Refer to the Toyota Owner’s Manual for a list of additional situations in which the
system may not operate properly.
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.

Refer to the Toyota Owner’s Manual for additional information on PCS operation,
settings adjustments, limitations, and precautions before attempting to use it. 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.

may also help to detect a pedestrian or bicyclist in front of your vehicle using the
forward-facing camera and front grille-mounted radar. The forward-facing camera
of PCS detects a potential pedestrian or bicyclist based on size, profile, and motion
of the detected pedestrian or bicyclist. However, a pedestrian or bicyclist may not
be detected depending on the conditions, including the surrounding brightness
and the motion, posture, size, and angle of the potential detected pedestrian or
bicyclist, preventing the system from operating or engaging.

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.
#3",&"44*45 #"

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.

Floor mat installation
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.

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.
