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

go back to the menu.
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.

DISABLING THE STEERING ASSIST FUNCTION
(1) Press “” switches to find and select .
(2) Press “
or ” switches to find the setting function and then press
“
”. The LDA Steering Assist system will be disabled.
(3) You can press “
” to go back to the menu.
Note: Operation of the LDA system and setting adjustments continues in the same
condition regardless of Ignition cycle until changed by the driver or the system is reset.
ADJUSTING LDA ALERT SENSITIVITY
The driver can adjust the sensitivity of the LDA (warning) function from the
Multi-Information Display (MID) customization screen.
High - Is designed to warn approximately before the front tire crosses the
lane marker.
Normal - Is designed to warn approximately when the front tire crosses
the lane marker.
(1) Press “
” switches to find and select .
(2) Press “
or ” switches to find the setting function and then press
“
”. The setting screen is displayed.
(3) Select “Sensitivity” and then press “
.” Each time “” is pressed, the
response to the LDA alert sensitivity changes. You can press “
” to go back to
the menu.
Note: Operation of the LDA system and setting adjustments continues in the
same condition regardless of Ignition cycle until changed by the driver or the
system is reset.
THE SWAY WARNING SYSTEM (SWS) FUNCTION
SWS is a function of LDA and is designed to detect swaying based on the vehicle
location in the lane and the driver’s steering wheel operation. To help prevent
swaying, the system alerts the driver using a buzzer sound and a warning displays
in the MID.
Continuous lane deviations from
swaying.
Gentle swaying from driver’s
inattentiveness.
Acute steering wheel operation after the
number of operations decrease due to driver’s
inattentiveness.

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).
