FEATURES & OPERATIONS
When traveling at a low
speed and the brake
pedal is not depressed,
or is depressed late.When the accelerator
pedal is depressed
excessively.
When the vehicle moves in
the unintended direction
due to the wrong shift
position being selected.
When reversing, a vehicle is
approaching and the brake pedal is
not depressed, or is depressed late. When a pedestrian is detected
behind the vehicle while backing up,
the brake pedal is not depressed or
is depressed late.
Front and Rear Parking Assist with Automated Braking consists of the fol\
lowing
functions that operate when driving at a low speed or backing up, such a\
s when
parking. When the system determines that the possibility of a collision \
with a
detected object is high, a warning operates to urge the driver to take e\
vasive
action. If the system determines that the possibility of a collision wit\
h a detected
object is extremely high, the brakes are automatically applied to help a\
void the
collision or help reduce the impact of the collision.

PRE-COLLISION SYSTEM (CONTINUED)
TOYOTA SAFETY SENSE™
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-I\
nformation
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 m\
ay apply
greater braking force in relation to how strongly the brake pedal is dep\
ressed.
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
system may automatically apply the brakes, reducing speed in order to he\
lp the
driver reduce the impact and in certain cases avoid the collision.
Refer to the Toyota Owner’s Manual for additional information on PCS \
operation,
settings adjustments, limitations, and precautions before attempting to \
use it.
Monocular camera sensorMillimeter
wave radar
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 the Toyota Owner’s Manual for additional limitations and inf\
ormation. Under certain conditions, the PCS system included with the TSS 2.5+ pack\
age
may also help to detect a pedestrian or bicyclist in front of your vehic\
le 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, profil\
e, and motion
of the detected pedestrian or bicyclist. However, a pedestrian or bicycl\
ist may not
be detected depending on the conditions, including the surrounding brigh\
tness
and the motion, posture, size, and angle of the potential detected pedes\
trian or
bicyclist, preventing the system from operating or engaging.

ADJUSTING DISTANCE
This mode employs a radar sensor to detect the presence of a preceding v\
ehicle
up to approximately 328 ft (100 m) ahead, determines the current vehic\
le-to-vehicle
following distance and operates to maintain a preset following distance \
from the
vehicle ahead. These distances vary based on vehicle speed.
(1) (2) (3)
(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 dis\
tance
control.
(2) Deceleration cruising and follow-up cruising when a preceding vehicle
driving slower than the set speed appears When a slower vehicle is detected running ahead of you, the system
automatically decelerates your vehicle. When a greater reduction in vehi\
cle
speed is necessary, the system may apply the brakes (the brake lights w\
ill
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 b\
y the
driver. A warning tone warns you when the system cannot decelerate suffi\
ciently
to prevent your vehicle from closing in on the vehicle ahead.
Note: Vehicle-to-vehicle distance will close in when traveling on long downhill
slopes.

Star Safety System™
SAFETY & EMERGENCY FEATURES
Your vehicle comes standard with the Star Safety SystemTM, 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).
Refer to the Owner’s Manual for more details and important informatio\
n on
limitations to these systems.
Enhanced Vehicle Stability Control provides cooperative control of the A\
BS, TRAC,
VSC and EPS.
Enhanced VSC helps to maintain directional stability when loss of tracti\
on occurs
during a turn.
ENHANCED VEHICLE STABILITY CONTROL (VSC)
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.
ANTI-LOCK BRAKE SYSTEM (ABS)
Toyota’s ABS technology has Electronic Brake-force Distribution (EBD\
) to help
maintain control and balance when braking. EBD responds to sudden stops \
by
redistributing brake force to enhance the braking effectiveness of all f\
our wheels.
ELECTRONIC BRAKE FORCE DISTRIBUTION (EBD)
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 qui\
ckly than
just the driver alone can.
BRAKE ASSIST (BA)
SMART STOP TECHNOLOGY (SST)
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.
VSC helps prevent loss of traction during cornering by reducing Motor po\
wer
output, 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 star\
ts to slip.
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.
