porarily canceled. However, when
the operation conditions are met
again, operation of the function is
automatically restored. ( P.211)
■Steering assist function
●Depending on the vehicle speed,
lane departure situation, road con-
ditions, etc., the driver may not
feel the function is operating or
the function may not operate at
all.

■Hands off steering wheel warn-
ing
In the following si tuations, a warning
message urging the driver to hold
the steering wheel and the symbol
shown in the illustration are dis-
played on the multi-information dis-
play to warn the driver. The warning
stops when the system determines
that the driver holds the steering
wheel. Always keep your hands on
the steering wheel when using this
system, regardle ss 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 small amount.
●When the system determines that
the vehicle may not turn and
instead depart from its lane while
driving around a curve
Depending on the vehicle condition
and road conditions, the warning
may not operate. Also, if the system
determines that the vehicle is driv- ing around a curve, warnings will
occur earlier than during
straight-lane driving.
●When the system determines that
the driver is driving without hold-
ing the steering wheel while the
steering wheel assist of the steer-
ing assist function is operating.
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
When the system determines that
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 simultaneously dis-
played on the multi-information dis-
play.
Depending on the vehicle and road
conditions, the warning may not
operate.
■Warning message
If the following warning message is
displayed on the multi-information
display and the LDA indicator illumi-
nates in orange, follow the appropri-
ate troubleshooting procedure. Also,
if a different warning message is
displayed, follow the instructions
displayed on the screen.

Driving
The system may not be operating
properly. Have the vehicle inspected
by your Toyota dealer.
●“LDA Unavailable”
The system is temporarily canceled
due to a malfunction in a sensor
other than the front camera. Turn
the LDA system off, wait for a little
while, and then turn the LDA system
back on.
●“LDA Unavailable at Current
Speed”
The function cannot be used as the
vehicle speed exceeds the LDA
operation range. Drive slower.
●“LDA Unavailable Below Approx.
32MPH”
The LDA system cannot be used as
the vehicle speed is less than
approximately 32 mph (50 km/h).
Drive the vehicle at approximately
32 mph (50 km/h) or more.
■If a battery terminal has been
disconnected and reconnected
The system needs to be initialized.
To initialize the system, drive the
vehicle straight ahead for 5 seconds
or more at a speed of approximately
22 mph (35 km/h) or more.

Driving
When the turn signal lever is operated and your vehicle moves to a left lane
while driving at 50 mph (8 0 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 pr eceding vehicles driving slower
than the set speed
The system accelerates until the set speed is reached. The system then
returns to constant speed cruising.
1 Press 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
again to deactivate the cruise con-
trol.
If the cruise control main switch is
pressed and held for 1.5 seconds
or more, the system turns on in
constant speed control mode.
( P.220)
2 Accelerate or decelerate,
with accelerator pedal opera-
tion, to the desired vehicle
speed (at or above approxi-
mately 20 mph [30 km/h])
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
set speed.
To change the set speed, press
the “+RES” or “-SET” switch
until the desired set speed is
displayed.

Pressing the switch changes the
vehicle-to-vehicle distance as
follows:
1 Long
2 Medium

cient automatic deceleration via
the cruise control is not possi-
ble, the display will flash and the
buzzer will sound to alert the
driver. An example of this would
be if another driver cuts in front
of you while you are following a
vehicle. Depress the brake
pedal to ensure an appropriate
vehicle-to-vehicle distance.
■Warnings may not occur
when
In the following instances, warn-
ings may not occur even when
the vehicle-to-vehicle distance is
small.
 When the speed of the pre-
ceding vehicle matches or
exceeds your vehicle speed
 When the preceding vehicle is
traveling at an extremely slow
speed
 Immediately after the cruise
control speed was set
 When depressing the acceler-
ator pedal When constant speed control
mode is selected, your vehicle
will maintain a set speed without
controlling the vehicle-to-vehi-
cle distance. Select this mode
only when vehicle-to-vehicle dis-
tance control mode does not
function correctly due to a dirty
radar, etc.

With the cruise control off,
press and hold the cruise
control main switch for 1.5
seconds or more.
Immediately after the switch is
pressed, the dynamic radar cruise
control indicator will come on. After-
wards, it switches to the cruise con-
trol indicator.
Switching to constant speed control
mode is only possible when operat-
ing the switch with the cruise con-
trol off.

with accelerator pedal opera-
tion, to the desired vehicle

If constant speed control mode is
automatically canceled for any rea-

■Brake operation
A brake operation sound may be
heard and the brake pedal response
may change, but these are not mal-
functions.
■Warning messages and buzzers
for dynamic radar cruise con-
trol with full-speed range
Warning messages and buzzers are
used to indicate a system malfunc-
tion or to inform the driver of the
need for caution while driving. If a
warning message is shown on the
multi-information display, read the
message and follow the instructions.
(  P.185, 490)
■When the sensor may not be
correctly detecting the vehicle
ahead
In the case of the following and
depending on the conditions, oper-
ate the brake pedal when decelera-
tion of the system is insufficient or
operate the accelerator pedal when
acceleration is required.
As the sensor may not be able to
correctly detect these types of vehi-
cles, the approach warning
(  P.219) may not be activated.
●Vehicles that cut in suddenly
●Vehicles traveling at low speeds
●Vehicles that are not moving in the
same lane
●Vehicles with small rear ends
(trailers with no load on board,
etc.)
●Motorcycles traveling in the same
lane
●When water or snow thrown up by
the surrounding vehicles hinders
the detecting of the sensor
●When your vehicle is pointing
upwards (caused by a heavy load
in the luggage compartment, etc.)
●Preceding vehicle has an
extremely high ground clearance
■Conditions under which the
vehicle-to-vehicle distance con-
trol mode may not function cor-
rectly
In the case of the following condi-
tions, operate the brake pedal (or
accelerator pedal, depending on the
situation) as necessary.
As the sensor may not be able to
correctly detect vehicles ahead, the
system may not operate properly.
