2184-2. Driving procedures
■When an inspection at your
Toyota dealer is necessary
When the brake hold standby indi-
cator (green) does not illuminate
even when the brake hold switch is
pressed with the brake hold system
operating conditions met, the sys-
tem may be malfunctioning. Have
the vehicle inspected at your Toyota
dealer.
■If “Brake Hold Malfunction
Press Brake to Deactivate Visit
Your Dealer” or “Brake Hold
Malfunction Visit Your Dealer”
is displayed on the multi-infor-
mation display
The system may be malfunctioning.
Have the vehicle inspected by your
Toyota dealer.
■Warning messages and buzzers
Warning messages and buzzers are
used to indicate a system malfunc-
tion or to inform the driver of the
need for caution. If a warning mes-
sage is shown on the multi-informa-
tion display, read the message and
follow the instructions.
■If the brake hold operated indi-
cator flashes
P.454
WARNING
■When the vehicle is on a
steep incline
Take care when using the brake
hold system on a steep incline,
exercise caution. The brake hold
function may not hold brakes in
such situations.
Also, the system may not activate
depending on the angle of the
slope.
■When stopped on a slippery
road
The system cannot stop the vehi-
cle when the gripping ability of the
tires has been exceeded. Do not
use the system w hen stopped on
a slippery road.
NOTICE
■When parking the vehicle
The brake hold system is not
designed for use when parking
the vehicle for a long period of
time. Turning the engine switch
off while the system is holding the
brake may release the brake,
which would cause the vehicle to
move. When operating the engine
switch, depress the brake pedal,
shift the shift lever to P and set
the parking brake.
2204-3. Operating the lights and wipers
Canada
1 The side marker, park-
ing, tail, license plate, instru-
ment panel lights, and
daytime running lights
( P.220) turn on.
2 The headlights and all
lights listed above (except
daytime running lights) turn
on.
3 The headlights, daytime
running lights ( P.220) and
all the lights listed above turn
on and off automatically.
■AUTO mode can be used when
The engine switch is in ON.
■Daytime runni ng light system
●Vehicles with multi-LED head-
lights and LED projector head-
lights with bulb type front turn
signal lights: The daytime running
lights illuminate u sing the same
lights as the low beam headlights
and illuminate d immer than the
low beam headlights.
●Vehicles with LED projector head-
lights with LED type front turn sig-nal lights: The daytime running
lights illuminate using the same
lights as the parking lights and illu-
minate brighter than the parking
lights.
●To make your vehicle more visible
to other drivers
during daytime
driving, the daytime running lights
turn on automatically when all of
the following conditions are met.
(The daytime running lights are
not designed for use at night.)
• The engine is running
• The parking brake is released
• For the U. S. A.: The headlight
switch is in the , or
*
position
• For Canada: The headlight switch
is in the or
* position
*: When the surroundings are bright
The daytime running lights remain
on after they illumi nate, even if the
parking brake is set again.
●For the U.S.A.: Daytime running
lights can be turned off by operat-
ing the switch.
●Compared to turning on the head-
lights, the daytime running light
system offers greater durability
and consumes less electricity, so
it can help improve fuel economy.
■Headlight control sensor (if
equipped)
The sensor may not function prop-
erly if an object is placed on the sen-
sor, or anything that blocks the
sensor is affixed to the windshield.
Doing so interferes with the sensor
detecting the level of ambient light
and may cause t he automatic head-
light system to malfunction.

The system can detect the fol-
lowing (The detectable objects
differs depending on the func-
tion.):
Vehicles

Pedestrians
■Pre-collision warning
When the system determines
that the possibility of a frontal
collision is high, a buzzer will
sound and a warning message
will be displayed on the multi-
information display to urge the
driver to take evasive action.
■Pre-collision brake assist
When the system determines
that the possibility of a frontal
collision is high, the system
applies greater braking force in
relation to how strongly the
brake pedal is depressed.
■Pre-collision braking
If the system determines that
the possibility of a frontal colli-
sion is extremely high, the
brakes are automatically applied
to help avoid the collision or
reduce the impact of the colli-
sion.
■Emergency steering assist
If the system determines that
the possibility of a collision with
PCS (Pre-Collision Sys-
tem)
The pre-collision system
uses a radar sensor and
front camera to detect
objects ( P.239) in front of
the vehicle. When the sys-
tem determines that the
possibility of a frontal colli-
sion with an object is high,
a warning operates to urge
the driver to take evasive
action and the potential
brake pressure is increased
to help the driver avoid the
collision. If the system
determines that the possi-
bility of a frontal collision
with an object is extremely
high, the brakes are auto-
matically applied to help
avoid the collision or help
reduce the impact of the
collision.
The pre-collision system can
be disabled/enabled and the
warning timing can be
changed. ( P.242)

WARNING
●Although this system is
designed to help avoid a colli-
sion or help reduce the impact
of the collision, its effectiveness
may change according to vari-
ous conditions, therefore the
system may not always be able
to achieve the same level of
performance.
Read the following conditions
carefully. Do not overly rely on
this system and always drive
carefully.
• Conditions under which the sys- tem may operate even if there is
no possibility of a collision:
P.245
• Conditions under which the sys- tem may not operate properly:
P.247
●Do not attempt to test the oper-
ation of the pre-collision system
yourself.
Depending on the objects used
for testing (dummies, card-
board objects imitating detect-
able objects, etc.), the system
may not operate properly, pos-
sibly leading to an accident.
■Pre-collision braking
●When the pre-collision braking
function is operating, a large
amount of braking force will be
applied.
●If the vehicle is stopped by the
operation of the pre-collision
braking function, the pre-colli-
sion braking function operation
will be canceled after approxi-
mately 2 second s. Depress the
brake pedal as necessary.
●The pre-collision braking func-
tion may not operate if certain
operations are performed by the
driver. If the accelerator pedal is
being depressed strongly or the
steering wheel is being turned,
the system may determine that
the driver is taking evasive
action and possibly prevent the
pre-collision braking function
from operating.
●In some situations, while the
pre-collision brak ing function is
operating, operation of the func-
tion may be canceled if the
accelerator pedal is depressed
strongly or the steering wheel is
turned and the system deter-
mines that the driver is taking
evasive action.
●If the brake pedal is being
depressed, the system may
determine that t he driver is tak-
ing evasive action and possibly
delay the operation timing of the
pre-collision braking function.
■Emergency steering assist
●As emergency steering assist
operation will be canceled when
the system determines that lane
departure prevention function
has been completed.
●Emergency steering assist may
not operate or may be cancel in
the following cases as the sys-
tem may determine the driver is
taking actions.
• If the accelerator pedal is being depressed strongly, the steering
wheel is being operated
sharply, the brake pedal is
being depressed or the turn sig-
nal lever is being operated. In
this case, the system may
determine that t he driver is tak-
ing evasive action and the
emergency steering assist may
not operate.

●Pre-collision warning
While the pre-collision warning function is operating, if the steering wheel is
operated heavily or suddenly, the pre -collision warning may be canceled.
●Pre-collision brake assist
●Pre-collision braking
If either of the following occur while the pre-collision braking function is oper-
ating, it will be canceled:
• The accelerator pedal is depressed strongly.
• The steering wheel is turned sharply or abruptly.
●Emergency steering assist
When the turn signal lights are flashing, emergency steering as sist will not
operate in case of an emergency.
If any of the following occur wh ile the emergency steering assi st function is
operating, it will be canceled:

●Intersection right/left turn assistance (pre-collision warning)
When the turn signal lights are not flashing, support for turning left or right at
an intersection which targets on coming vehicles does not work.
●Intersection right/left turn assistance (pre-collision braking)
When the turn signal lights are not flashing, support for turning left or right at
an intersection which targets on coming vehicles does not work.
■Object detection function
The system detects objects based
on their size, profile, motion, etc.
However, an object may not be
detected depending on the sur-
rounding brightness and the motion,
posture, and angle of the detected
object, preventing the system from
operating properly. ( P.247)

• If the wheels are misaligned
• If a wiper blade is blocking the front camera
• The vehicle is being driven at extremely high speeds
• When driving on a hill
• If the radar sensor or front camera
is misaligned
• When driving in a traffic lane sep-
arated by more t han one lane
where oncoming vehicles are driv-
ing while making a right/left turn
• When largely out of place with the opposite facing targeted oncom-
ing vehicle during a right/left turn
• While making a right/left turn, when a pedestrian approaches
from behind or side of your vehicle
●In addition to the above, in some
situations, such as the following,
the emergency steering assist
may not operate.
• When the white (yellow) lane lines are difficult to see, such as when
they are faint, di verging/merging,
or a shadow is cast upon them • When the lane is wider or nar-
rower than normal
• When there is a light and dark pat-
tern on the road surface, such as
due to road repairs
• When a pedestrian is detected
near the centerline of the vehicle
• When the target is too close
• When there is insufficient safe or unobstructed space for the vehicle
to be steered into
• If oncoming vehicle is present
• If VSC function is operating
●In some situations such as the fol-
lowing, sufficient braking force or
steering force may not be
obtained, preventing the system
from performing properly:
• If the braking functions cannot operate to their full extent, such as
when the brake parts are
extremely cold, ext remely hot, or
wet
• If the vehicle is not properly main- tained (brakes or tires are exces-
sively worn, imprope r tire inflation
pressure, etc.)
• When the vehicle is being driven on a gravel road or other slippery
surface
• When the road surface has deep wheel tracks
• When driving on a hill road
• When driving on a road that has inclines to the left or right
■If VSC is disabled
●If VSC is disabled ( P.320), the
pre-collision brak e assist and pre-
collision braking functions are also
disabled.
●The PCS warning light will turn on
and “VSC Turned Off Pre-Colli-
sion Brake System Unavailable”
will be displayed on the multi-
information display.

Driving
This mode employs a radar 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 fol-
lowing distance from the vehicle ahead. The desired vehicle-to- vehi-
cle distance can also be set by operating the vehicle-to-vehicl e
distance switch.
When driving on downhill slopes, t he vehicle-to-vehicle distance may
become shorter.
Example of constant speed cruising
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 i n the speed of the vehicle
ahead in order to maintain the ve hicle-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 performed, system
