pedestrians nearby■Temporarily lowering sensor
sensitivity
The sensitivity of the sensor can be
temporarily lowered.
1 Turn the power s witch off while
the following conditions are met.
●The headlight switch is in or
.
●The headlight switch lever is in
low beam position.
●Automatic High Beam switch is
on.
2 Turn the power switch to ON.
3 Within 60 seconds after step 2,
repeat pushing the headlight
switch lever to the high beam
position then pulling it to the orig-
inal position quickly 10 times,
then leave the lever in the origi-
nal position.
4 If the sensitivity is changed, the
AHB indicator is turn on and off 3
times.
Automatic High Beam (headlights)
may turn on even when the vehicle
is stopped.
■Switching to the high
beams
Push the lever away from you.
The AHB indicator will turn off and

wards, the Automatic High
Beam system will be activated
again.
■Temporarily switching to the
low beams
It is recommended to switch to the
low beams when the high beam
may cause problems or distress to
other drivers or pedestrians nearby.

2384-3. Operating the lights and wipers
Owners Manual_USA_M0C043_enmode while the powe
r switch is in
ON, the wipers will operate once
to show that AUTO mode is acti-
vated.
●If the temperature of the raindrop
sensor is 185°F (85°C) or higher,
or 5°F (-15°C) or lower, automatic
operation may not occur. In this
case, operate the wipers in any
mode other than AUTO mode.
■If no windshield washer fluid
sprays
Check that the wash er nozzles are
not blocked if there is washer fluid in
the windshield washer fluid reser-
v oi r.
WARNING
■Caution regarding the use of
windshield wipers 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 any-
thing else do not become caught
in the windshield wipers.
■Caution regarding the use of
washer fluid
When it is cold, do not use the
washer fluid until 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 there is no washer fluid
spray from the nozzle
Damage to the washer fluid pump
may be caused if the lever is
pulled toward you and held con-
tinually.
■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 12-volt battery dis-
charge
Do not leave the wipers on longer
than necessary when the hybrid

WARNING
●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 accelerato r pedal is being
depressed strongly, the steering
wheel is being operated sharply,
the brake pedal is being
depressed or the turn signal
lever is being ope rated. In this
case, the system may deter-
mine that the driver is taking
evasive action and the emer-
gency steering assist may not
operate.
• The emergency steering assist will be disabled automatically
when the system judges that a
trailer is connected.
• In some situations, while the emergency steering assist is
operating, operation of the func-
tion may be canceled if the
accelerator peda l is depressed
strongly, the st eering wheel is
operated sharply or the brake
pedal is being depressed and
the system determines that the
driver is taking evasive action.
• When the emergency steering assist is operating, if the steer-
ing wheel is held firmly or is
operated in the opposite direc-
tion to that which the system is
generating torque, the function
may be canceled.
■When to disable the pre-colli-
sion system
In the following situations, disable
the system, as it may not operate
properly, possibly leading to an
accident resulting in death or seri-
ous injury:
●When the vehicle is being towed
●When your vehicles is towing a
trailer or another vehicle, except
when the followin g conditions
are all met
• When the other vehicle is a trailer properly attached and
connected to Toyota’s official
TBC ECU. ( P.198)
• When the vehicle is not being driven on a slippery surface
such as an icy road or a very
wet road.
●When transporting the vehicle
via truck, boat, train or similar
means of transportation
●When the vehicle is raised on a
lift with the hybrid system on
and the tires are allowed to
rotate freely
●When inspecting the vehicle
using a drum tester such as a
chassis dynamometer or speed-
ometer tester, or when using an
on vehicle wheel balancer
●When a strong impact is applied
to the front bumper or front
grille, due to an accident or
other reasons
●If the vehicle cannot be driven in
a stable manner, such as when
the vehicle has been in an acci-
dent or is malfunctioning
●When the vehicle is driven in a
sporty manner or off-road
●When the tires are not properly
inflated
●When the tires are very worn
●When tires of a size other than
specified are installed
●When tire chains are installed
●When a compact spare tire or
an emergency tire puncture
repair kit is used

grounds, closely following vehi-
cles such traffic jam, drive
through, parallel parking, etc.
●Do not use the lane centering
system and steering assist func-
tion when the vehicle is lifted
unless using a Toyota official lift
up kit up to 4 in. (101 mm),
including tire height. Aftermar-
ket lift kits may degrade system
performance.

met.
• When the other vehicle is a trailer properly attached and
connected to Toyota’s official
TBC ECU. ( P.198)
●When the vehicle is lifted up,
except in the following cases.
• When using a Toyota official lift kit up to 4 in. (101 mm), includ-
ing tire height. Aftermarket lift
kits may degrade system perfor-
mance.
■Preventing LTA system mal-
functions and operations per-
formed by mistake

Owners Manual_USA_M0C043_en• Steering assist function is not
operating.
• When your vehicle is not towing a
trailer or during emergency tow-
ing.
■Temporary cancelation of func-
tions
●When operation conditions are no
longer met, a function may be
temporarily canceled. However,
when the operation conditions are
met again, operation of the func-
tion is automatically restored.
( P.269)
●If the operation conditions
( P.269) are no longer met while
the lane centering function is
operating, the steering wheel may
vibrate and the buzzer may sound
to indicate that the function has
been temporarily canceled. How-
ever, if the “Alert” customization
setting is set to , the system
will notify the driver by vibrating
the steering wheel instead of
sounding the buzzer.

wheel. Always keep your hands on
the steering wheel when using this
system, regardless of warnings.
●When the system determines that
the driver is driving without hold-
ing the steering wheel while the
system is operating
If the driver continues to keep their
hands off of the steering wheel, the
buzzer sounds, the driver is warned
and the function is temporarily can-
celed. This warning also operates in
the same way when the driver con-
tinuously operates the steering
wheel only a s mall amount.
The buzzer also sounds even if the
alert type is set to .
●When the system determines that
the vehicle may deviate from the
lane while driving around a curve
