Sensors
TSS combines an in-vehicle camera mounted in front of the inside rear vi\
ew mirror and
a radar mounted in the front grill. These sensors support the driver ass\
ist systems.
The Pre-Collision System uses a radar sensor and camera sensor to help d\
etect a
vehicle or pedestrian or bicyclist in front of your vehicle.
As there is a limit to the degree of recognition accuracy and control pe\
rformance 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 n\
ot use PCS
instead of normal braking operations under any circumstances. Do not att\
empt to test
the operation of the Pre-Collision System yourself, as the system may no\
t operate or
engage, possibly leading to an accident. In some situations, such as whe\
n 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 pedes\
trian 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.
Pre-Collision Warning
When the system determines that the possibility of a frontal collision i\
s high, a buzzer
will sound and a warning message will be displayed on the Multi-Informat\
ion 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 addi\
tional 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.

TOYOTA SAFETY SENSE™
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 tha\
t the possibility
of a frontal collision with a preceding vehicle is extremely high, the s\
ystem may
automatically apply the brakes, reducing speed in order to help the driv\
er reduce the
impact and in certain cases avoid the collision.

As part of the Pre-Collision System, this function is also designed to f\
irst provide an
alert and then automatic braking if needed.
Refer to a Toyota Owner’s Manual for additional limitations and infor\
mation.Under certain conditions, the PCS system included with the TSS-P package\
may
also help to detect a pedestrian in front of your vehicle using the in-v\
ehicle camera
and front-grill mounted millimeter wave radar. The in-vehicle camera of \

Enhanced Vehicle Stability Control provides cooperative control of the A\

Toyota’s ABS sensors detect which wheels are locking up and limits wh\
eel lockup
by “pulsing” each wheel’s brakes independently. Pulsing release\
s brake pressure
repeatedly for fractions of a second. This helps the tires attain the tr\
action that
current road conditions will allow, helping you to stay in directional c\
ontrol.

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\

Smart Stop Technology automatically reduces motor power when the acceler\
ator
and brake pedals are pressed simultaneously under certain conditions.
SST engages when the accelerator is depressed first and the brakes are a\
pplied
firmly for longer than one-half second at speeds greater than five miles\
per hour.
SST doesn’t engage if the brake pedal is depressed before the acceler\
ator pedal,
allowing vehicles to start on a steep hill and safely accelerate without\
rolling
backward.

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.
• 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 Δ marks

Toyota’s TRAC sensors are activated when one of the drive wheels star\

TRAC limits Motor power output and applies the brakes to the spinning wh\
eel. This
transfers power to the wheels that still have traction to help keep you \
on track.
