alert and then automatic braking if needed.In certain conditions, the PCS system included with the TSS-P package ma\
y 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 ra\
dar 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 depen\
ding
on the conditions, including the surrounding brightness and the motion, \
posture,
size, and angle of the potential detected pedestrian, preventing the sys\
tem from
operating or engaging. Refer to a Toyota Owner’s Manual for additional information.

DISABLING PRE-COLLISION SYSTEM (PCS)
LDA in TSS-P uses an in-vehicle camera designed to detect visible white \
and
yellow lane markers in front of the vehicle and the vehicle’s positio\
n on the road.
If the system determines that the vehicle is starting to unintentionally\
deviate from
its lane, the system alerts the driver with an audio and visual alert. W\
hen the alerts
occur, the driver must check the surrounding road situation and carefull\
y operate
the steering wheel to move the vehicle back to the center part of their \
lane.
LDA is designed to function at speeds of approximately 32 MPH or higher \
on
relatively straight roadways.
In addition to the alert function, LDA w/SA also features a steering ass\
ist
function. When enabled, if the system determines that the vehicle is on \
a path
to unintentionally depart from its lane, the system may provide small co\
rrective
steering inputs to the steering wheel for a short period of time to help\
keep the
vehicle in its lane.

TURNING THE LDA SYSTEM ON/OFF
Press the LDA switch to turn the LDA system on. Depress again to turn it\
off.
Note: The system will continue in the last state it was in (ON or OFF) when the engine is
started again.
Refer to a Toyota Owner’s Manual for additional information on LDA op\
eration,
settings adjustments, limitations, and precautions before attempting to \
use it.

The LDA function
displays when the Multi-Information Display (MID) is
switched to the driving assist system information screen.
(1) The system displays solid white lines on the LDA indicator when visible lane
markers on the road are detected. A side flashes orange to alert the dri\
ver when the
vehicle deviates from its lane.
(2) The system displays outlines on the LDA indicator when lane markers on the
road are not detected or the function is temporarily cancelled.
Note: When operation conditions are no longer met, a function may be temporarily
canceled. However, when the operation conditions are met again, operation of the
function is automatically restored. For example, LDA may not function on the side(s)
where white/yellow lines are not detectable.

Automatic High Beams (AHB)
(1) With the engine switch in IGNITION ON mode and headlight switch turned to “AUTO” position, push lever away from you.
The “
” indicator will come on when the headlights are turned on
automatically to indicate that the system is active.
(2) Pull the lever back toward you to turn the AHB system off.
The “
” will turn off and the “” turns on.
When all of these conditions are met, high beams will be automatically t\
urned on
(after approximately 1 second): • Vehicle speed is above approximately 20 mph (32 km/h).
• The area ahead of the vehicle is dark.
• There are no oncoming or preceding vehicles with headlights or tail\
lights turned on.
• There are few street lights on the road ahead.
If any of these conditions occur, the system is designed to automaticall\
y turn off
high beams: • Vehicle speed drops below approximately 20 mph (32 km/h).
• The area ahead of the vehicle is not dark.
• Oncoming or preceding vehicles have headlights or tail lightsturned on.
• There are many streetlights on the road ahead.
ACTIVATING THE AHB SYSTEM
CONDITIONS WHERE AHB WILL TURN ON/OFF AUTOMATICALLY
AHB is a safety system designed to help drivers see more of what’s ah\
ead at
nighttime and reduce glare for oncoming drivers. When enabled, AHB uses \
an
in-vehicle camera to help detect the headlights of oncoming vehicles and\
tail lights
of preceding vehicles, then automatically switches between high and low \
beams
as appropriate to provide the most light possible and enhance forward vi\
sibility.
By using high beams more frequently, the system may allow earlier detect\
ion of
pedestrians and obstacles.
Refer to the Toyota Owner’s Manual for additional information on AHB \
operation,
settings adjustments, limitations, and precautions before attempting to \
use it.

SAFETY & EMERGENCY FEATURES
Star Safety System™
VEHICLE STABILITY CONTROL (VSC)
VSC helps prevent loss of traction during cornering by reducing engine p\
ower and
applying brake force to selected wheels.
Toyota’s VSC monitors steering angle and the direction your vehicle i\
s 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 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 (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 qui\
ckly 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. EBD responds to sudden stops \
by
redistributing brake force to enhance the braking effectiveness of all f\
our 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).
Refer to the Owner’s Manual for more details and important information on limitations
to these systems.
SMART STOP TECHNOLOGY (SST)
Smart Stop Technology automatically reduces engine power when the accele\
rator
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
TRACTION CONTROL (TRAC)
VSC helps prevent loss of traction during cornering by reducing engine p\
ower, and
Traction Control helps maintain traction on loose gravel and wet, icy, o\
r 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 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 Δ marks
