AHB (Automatic High
Beam)
The Automatic High Beam
uses an in-vehicle front
camera to assess the bright-
ness of streetlights, the
lights of vehicles ahead etc.,
and automatically turns the
high beam on or off as nec-
essary.
WARNING
■Limitations of the Automatic
High Beam
Do not overly rely on the Auto-
matic High Beam. Always drive
safely, taking care to observe
your surroundings and turning the
high beam on or off manually if
necessary.
■To prevent incorrect opera-
tion of the Automatic High
Beam system
Do not overload the vehicle.

will not switch.)
Vehicles with rain-sensing wind-
shield wipers
With low speed windshield wiper
operation selected, wiper operation
will be switched from low speed to
intermittent wiper operation when
the vehicle is stationary. (However,
when the sensor s ensitivity is
adjusted to the highest level, the
mode will not switch.)
■Raindrop sensor (vehicles with
rain-sensing windshield wipers)
●The raindrop sensor judges the
amount of raindrops.
●If the wiper switch is turned to the
“AUTO” position while the engine
switch is in ON, the wipers will
operate once to show that “AUTO”
mode is activated.
●If the wiper sensitivity is adjusted
to higher, the wip er may operate
once to indicate the change of
sensitivity.
●If the temperature of the raindrop
sensor is 185°F (85°C) or higher,
or 5°F (-15°C) or lower, the auto-
matic operation m ay not occur. In
this case, operate the wipers in
any mode other than “AUTO”.
■If no windshield washer fluid
sprays
Check that the wash er nozzles are
not blocked if there is washer fluid in
the windshield was her fluid reser-
voir.
WARNING
■Caution regarding the use of
windshield wipe rs in “AUTO”
mode (vehicles with rain-
sensing windshield wipers)
The windshield wipers may oper-
ate unexpectedly if the sensor is
touched or the windshield is sub-
ject to vibration in “AUTO” mode.
Take care that your fingers or
anything else does not become
caught in the windshield wipers.
■Caution regarding the use of
washer fluid
When it is cold, do not use the
washer fluid unt il the windshield
becomes warm. The fluid may
freeze on the windshield and
cause low visibility. This may lead
to an accident, resulting in death
or serious injury.
NOTICE
■When the washer fluid tank is
empty
Do not operate the switch continu-
ally as the washer fluid pump may
overheat.
■When a nozzle becomes
blocked
In this case, contact your Toyota
dealer.
Do not try to clear it with a pin or
other object. The nozzle will be
damaged.
■To prevent battery discharge
Do not leave the wipers on longer
than necessary w hen the engine
is off.

driver.
When the warning buzzer sounds,
check the area around your vehicle
and carefully operate the steering
wheel to move the vehicle back to
the center of the lane.
Vehicles with BSM: When the sys-
tem determines that the vehicle
might depart from its lane and that

overtaking vehicle in the adjacent
lane is high, the lane departure
alert will operate even if the turn
signals are operating.

Driving
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
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 identifi cation of what is an overtaking lane may be deter-
mined solely based on the location of the steering wheel in the vehicle (left
side driver position versus righ t side driver position.) If the vehicle is driven
to a region where the overtaking lane is on a different side fr om where the
vehicle is normally driven, the v ehicle may accelerate when the turn signal
lever is operated in the opposite direction to the overtaking l ane (e.g., if the
driver normally operates the vehicle in a region where the over taking lane is
to the right but then drives to a region where the overtaking l ane 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.

2764-5. Using the driving support systems
■The system can be operated
when
●The engine switch is in ON.
●Intuitive parking assist function is
on.
●The vehicle speed is less than
about 6 mph (10 km/h).
●The shift lever is in a position
other than P.
■If “Parking Assist Unavailable
Clean Parking Assist Sensor” is
displayed on the multi-informa-
tion display
A sensor may be co vered with ice,
snow, dirt, etc. Remove the ice,
snow, dirt, etc., from the sensor to
return the system to normal.
Also, due to ice forming on a sensor
at low temperatures, a warning
message may be displayed or the
sensor may not be able to detect an
object. Once the ice melts, the sys-
tem will return to normal.
If a warning message is displayed
even if the sensor is clean, there
may be a sensor malfunction. Have
the vehicle inspected by your
Toyota dealer.
WARNING
■When to disable the function
In the following situations, disable
the function as it may operate
even though there is no possibility
of a collision.
●The vehicle is equipped with a
commercial fender pole, wire-
less antenna or fog lights.
●The front or rear bumper or a
sensor receives a strong
impact.
●A non-genuine Toyota suspen-
sion (lowered suspension, etc.)
is installed.
●Towing eyelets (if equipped) are
installed.
●A backlit license plate is
installed.
■When using the intuitive park-
ing assist
In the following s ituations, the
system may not function correctly
due to a sensor mal function, etc.
Have the vehicle checked by your
Toyota dealer.
●The intuitive parking assist
operation display flashes or
shows continuously, and a
buzzer sounds when no objects
are detected.
●If the area around a sensor col-
lides with something, or is sub-
jected to strong impact.
●If the bumper or grille collides
with something.
●If the display flashes or is dis-
played continuously and a
buzzer does not sound, except
when the mute function has
been turned on.
■Notes when washing the vehi-
cle
Do not apply intensive bursts of
water or steam to the sensor
area.
Doing so may result in the sensor
malfunctioning.
●When using a high pressure
washer to wash the vehicle, do
not spray the sensors directly,
as doing so may cause a sensor
to malfunction.
●When using steam to clean the
vehicle, do not direct steam too
close to the sensors as doing so
may cause a sensor to malfunc-
tion.
