While driving on a road with
clear white (yellow) lane lines,
the LTA system warns the driver
if the vehicle may deviate from
the current lane or course
*, and
also can slightly operate the
steering wheel to help avoid
deviation from the lane or
course
*. Also, while the dynamic
radar cruise control with full-
speed range is operating, this
system will operate the steering
wheel to maintain the vehicle’s
lane position.
The LTA system recognizes
white (yellow) lane lines or a
course
* using the front camera.
Additionally, it detects preceding
vehicles using the front camera
and radar.

When there are no vehicles ahead
The vehicle travels at the speed set by the driver.
Example of deceleration crui sing and follow-up cruising
When a preceding vehicle driving slower than the set speed
appears
When a vehicle is detected runni ng ahead of you, the system automatically
decelerates your vehicle. When a greater reduction in vehicle s peed is nec-
essary, the system applies the brakes (the stop 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.
Approach warning warns you when the system cannot decelerate suffi-
ciently to prevent your vehicle from closing in on the vehicle ahead.
When the vehicle ahead of you st ops, your vehicle will also stop (vehicle is
stopped by system control). Afte r the vehicle ahead starts off, pressing the
“+RES” switch or depressing the accelerator pedal (start-off operation) will
resume follow-up cruising. If the start-off operation is not pe rformed, system
control continues to keep your vehicle stopped.
When the turn signal lever is ope rated and your vehicle moves to an over-
taking lane while driving at 50 mph (80 km/h) or more, the vehi cle will accel-
erate to help to overt ake a passing vehicle.
The system’s identification of what is an overtaking lane may be determined
solely based on the location of the steering wheel in the vehicle (left side
driver position versus right side driver position.) If the vehi cle is driven to a
region where the overtaking lane is on a different side from wh ere the vehi-
cle is normally driven, the vehicle may accelerate when the tur n signal lever
is operated in the opposite direction to the overtaking lane (e .g., if the driver
normally operates the vehicle in a region where the overtaking lane is to the
right but then drives to a region where the overtaking lane is to the left, the
vehicle may accelerate when the right turn signal is activated).
Example of 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 constan t speed cruising.
1Press the cruise control main
switch to activate the cruise control.
Dynamic radar cruise control indi-
cator will come on and a message
will be displayed on
the multi-infor-
mation display. Press the switch

PKSB (Parking Sup-
port Brake)*
The Parking Support Brake
system consists of the fol-
lowing functions that oper-
ate when driving at a low
speed or backing up, such
as when parking. When the
system determines that the
probability of a collision
with a detected object or
pedestrian is high, a warn-
ing operates to urge the
driver to take evasive
action. If the system deter-
mines that the possibility of
a collision with a detected
object or pedestrian is
extremely high, the brakes
are automatically applied to
help avoid the collision or
help reduce the impact of
the collision.

Driving
When exiting from a parallel
parking space, if the system
determines that exit is possible
the parallel exiting function can
be used. Also, depending on the
surrounding environment, if it is
necessary to change the direc-
tion of travel of the vehicle, the
shift position can be changed by
assistance control.
NOTICE
■When using the parallel park-
ing function
●Make sure that there are no
obstructions within the yellow
guide lines and between the
vehicle and target parking spot.
If any obstructions are detected
within the yellow guide lines or
between the vehicle and the tar-
get parking space, the parallel
parking function will be can-
celled or suspended.
●As the target parking space will
not be able to be set correctly if
the surface of the parking space
is on a slope or has differences
in height, the vehicle may stray
from the target parking space or
be slanted. Therefore, do not
use the parallel parking func-
tion for this kind of parking spot.
●If an adjacent parked vehicle is
narrow or parked extremely
close to the curb, the position at
which assistance will park the
vehicle will also be close to the
curb. If it seems likely the vehi-
cle will collide with the curb or
drive off of the road, depress
the brake pedal to stop the vehi-
cle, and then press the
Advanced Park main switch to
disable the system.
●If there is a wall or other barrier
on the inner side of the parking
space, the vehicle may stop at a
position slightly outside of the
set target par king space.

space to the memory function, if
the road surface cannot be
detected “No available parking
space to register” will be dis-
played.
●When using the memory func-
tion, make sure to stop immedi-
ately in front of the stop
position. Otherwise the parking
space may not be able to be
detected correctly or assis-
tance may not be provided to
the point that the vehicle is fully
parked.
●Do not use the memory function
if a camera has been subjected
to a strong impac t or images of
the panoramic view monitor are
misaligned.

trol systems
●A sound may be heard from the
fuel cell unit compartment when
the brake pedal is depressed
repeatedly, when the fuel cell sys-
tem is started or just after the vehi-
cle begins to move. This sound
does not indicate that a malfunc-
tion has occurred in any of these
systems.
●Any of the following conditions
may occur when t he above sys-
tems are operating. None of these
indicates that a malfunction has
occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard also
after the vehicle comes to a stop. • The brake pedal
may pulsate
slightly after the ABS is activated.
• The brake pedal may move down
slightly after the ABS is activated.
■ECB operating sound
ECB operating sound may be heard
in the following cases, but it does
not indicate that a malfunction has
occurred.
●Operating sound heard from the
fuel cell unit compartment when
the brake pedal is operated.
●Motor sound of the brake system
heard from the f ront part of the
vehicle when the driver’s door is
opened.
●Operating sound heard from the
fuel cell unit compartment when
one or two minutes passed after
the stop of the fuel cell system.
■Active Cornering Assist opera-
tion sounds and vibrations
When the Active Cornering Assist is
operated, operation sounds and
vibrations may be generated from
the brake system, but this is not a
malfunction.
■EPS operation sound
When the steering wheel is oper-
ated, a motor sound (whirring
sound) may be heard. This does not
indicate a malfunction.
■Automatic reactivation of TRAC
and VSC systems
After turning th e TRAC and VSC
systems off, the systems will be
automatically re-enabled in the fol-
lowing situations:
●When the power switch is turned
off
●If only the TRAC sy stem is turned
off, the TRAC will turn on when
vehicle speed increases
If both the TRAC and VSC sys-
tems are turned of f, automatic re-
enabling will not occur when vehi-
cle speed increases.

WARNING
●When Active Cornering Assist
frequently operates, Active Cor-
nering Assist may temporarily
stop operating to ensure proper
operation of the brakes, TRAC
and VSC.
■Hill-start assist control does
not operate effectively when
●Do not overly rely on hill-start
assist control. Hill-start assist
control may not operate effec-
tively on steep inclines and
roads covered with ice.
●Unlike the parking brake, hill-
start assist control is not
intended to hold the vehicle sta-
tionary for an extended period
of time. Do not attempt to use
hill-start assist control to hold
the vehicle on an incline, as
doing so may lead to an acci-
dent.
■When the TRAC/ABS/VSC is
activated
The slip indicator light flashes.
Always drive carefully. Reckless
driving may cause an accident.
Exercise particular care when the
indicator light flashes.
■When the TRAC/VSC systems
are turned off
Be especially careful and drive at
a speed appropriate to the road
conditions. As these are the sys-
tems to help ensure vehicle stabil-
ity and driving force, do not turn
the TRAC/VSC systems off
unless necessary.
■Secondary Collision Brake
Do not rely solely upon the Sec-
ondary Collision Brake. This sys-
tem is designed to help reduce
the possibility of further damage
due to a secondary collision, how-
ever, that effect changes accord-
ing to various conditions. Overly
relying on the system may result
in death or serious injury.
■Replacing tires
Make sure that all tires are of the
specified size, brand, tread pat-
tern and total load capacity. In
addition, make sure that the tires
are inflated to the recommended
tire inflation p ressure level.
The ABS, TRAC and VSC sys-
tems will not functi on correctly if
different tires are installed on the
vehicle.
Contact your Toyota dealer for fur-
ther information when replacing
tires or wheels.
■Handling of tires and the sus-
pension
Using tires with any kind of prob-
lem or modifying the suspension
will affect the driving assist sys-
tems, and may cause a system to
malfunction.

3285-6. Driving tips
Owners Manual_USA_M62064_en
Perform the following according
to the driving conditions:
Do not try to forcibly open a
window or move a wiper that
is frozen. Pour warm water
over the frozen area to melt
the ice. Wipe away the water
immediately to prevent it from
freezing.
 To ensure proper operation of
the climate control system
fan, remove any snow that
has accumulated on the air
inlet vents in front of the wind-
shield.
 Check for and remove any
excess ice or snow that may
have accumulated on the
exterior lights, outside rear
view mirrors, windows, vehi-
cle’s roof, chassis, around the
tires or on the brakes.
 Remove any snow or mud
from the bottom of your shoes
before getting in the vehicle.
Accelerate the vehicle slowly,
keep a safe distance between
you and the vehicle ahead, and
drive at a reduced speed suit-
able to road conditions. 
Turn automatic mode of the
parking brake off. Otherwise,
the parking brake may freeze
and not be able to be
released automatically.
Also, avoid using the following
as the parking brake may
operate automatically, even if
automatic mode is off.
• Brake hold system
Park the vehicle and shift the
shift position to P without set-
ting the parking brake. The
parking brake may freeze up,
preventing it from being
released. If the vehicle is
parked without setting the
parking brake, make sure to
block the wheels.
Failure to do so may be dan-
gerous because it may cause
the vehicle to move unexpect-
edly, possibly leading to an
accident.
 When the parking brake is in
automatic mode, release the
parking brake after shifting
the shift position to P.
( P.192)
 If the vehicle is parked without
setting the parking brake,
confirm that the shift position
cannot be moved out of P.
 If the vehicle is left parked
with the brakes damp in cold
temperatures, there is a pos-
sibility of the brakes freezing.
