• When driving through steam or smoke
• When the surrounding area is dim,
such as at dawn or dusk, or while
at night or in a t unnel, making a
detectable object appear to be
nearly the same color as its sur-
roundings
• When driving in a place where the
surrounding brightness changes
suddenly, such as at the entrance
or exit of a tunnel
• After the hybrid system has started the vehicle has not been
driven for a certain amount of time
• While making a left/right turn and for a few seconds after making a
left/right turn
• While driving on a curve and for a
few seconds after driving on a
curve
• If your vehicle is skidding
• If the front of the vehicle is raised or lowered
• 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
●In some situations such as the fol-
lowing, sufficient braking force
may not be obtained, preventing
the system from performing prop-
erly:
• If the braking functions cannot operate to their full extent, such as
when the brake parts are
extremely cold, extremely 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
■If VSC is disabled
●If VSC is disabled ( P.222), the
pre-collision br ake assist and
pre-collision brakin g 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.

■Preventing LTA system mal-
functions and operations per-
formed by mistake

bars, kangaroo bar, etc.).
●If your windshield needs
repairs, contact your Toyota
dealer.
■Conditions in which functions
may not operate properly
In the following s ituations, the
functions may not operate prop-
erly and the vehicle may depart
from its lane. Drive safely by
always paying careful attention to
your surroundings and operate
the steering wheel to correct the
path of the vehicle without relying
solely on the functions.
●When the follow- up cruising dis-
play is displayed (P.187) and
the preceding vehicle changes
lanes. (Your vehicle may follow
the preceding vehicle and also
change lanes.)
●When the follow- up cruising dis-
play is displayed (
P.187) and
the preceding vehicle is sway-
ing. (Your vehicle may sway
accordingly and depart from the

If the driver continues to keep their
hands off of the steering wheel and
the steering wheel assist is operat-
ing, the buzzer sounds and the
driver is warned. Each time the
buzzer sounds, the continuing time
of the buzzer becomes longer.
■Vehicle sway warning function

the vehicle is swaying while the
vehicle sway warning function is
operating, a buzzer sounds and a
warning message urging the driver
to rest and the symbol shown in the
illustration are sim ultaneously dis-
played on the multi-information dis-
play.
Depending on the vehicle and road
conditions, the warning may not
operate.

due to a malfuncti on in a sensor
other than the front camera. Turn
the LTA system off, wait for a little
while, and then turn the LTA system
back on.

Speed”
The function cannot be used as the
vehicle speed exceeds the LTA
operation range. Drive slower.
■If a 12-volt battery terminal has
been disconnected and recon-
nected

■Before using dynamic radar
cruise control with full-speed
range
●Driving safely is the sole
responsibility of the driver. Do
not rely solely on the system,
and drive safely by always pay-
ing careful attent ion to your sur-
roundings.
●The dynamic radar cruise con-
trol with full-speed range pro-
vides driving assistance to
reduce the driver’s burden.
However, there are limitations to
the assistance provided.
Read the following conditions
carefully. Do not overly rely on this
system and always drive carefully.

1964-5. Using the driving support systems
COROLLA HV_UWhen the turn signal lever is operated and your vehicle moves t
o a left lane
while driving at 50 mph (80 km/h ) or more, the vehicle will quickly acceler-
ate to help to overtake a passing vehicle.
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-

and press the “-SET” switch
to set the speed.
Cruise control “SET” indicator will
come on.
The vehicle speed at the moment
the switch is released becomes the
