LDA in TSS 2.0 uses an in-vehicle camera designed to detect visible whit\
e and
yellow lane markers or road edge in front of the vehicle and the vehicle\
’s position
on the road. If the system determines that the vehicle is starting to un\
intentionally
deviate from its lane, the system alerts the driver with an audio and vi\
sual alert.
When the alerts occur, the driver must check the surrounding road situat\
ion and
carefully operate the steering wheel to move the vehicle back to the cen\
ter part of
their lane.
LDA is designed to function at speeds of approximately 32 mph (50 km/h)\
or higher
on relatively straight roadways.
In addition to the alert function, LDA w/SA also features a steering ass\
ist
function. When enabled, if the system determines that the vehicle is on \
a path to
unintentionally depart from its lane, the system may provide small corrective steering
inputs to the steering wheel for a short period of time to help keep the\
vehicle in its
lane.
If the vehicle repeatedly deviates from the lane, the vehicle drifts wit\
hin the lane due
to inattention, or the driver abruptly operates the steering wheel after\
an inattentive
period, when enabled, the vehicle sway warning function alerts the drive\
r with an
audio and visual alert, urging them to take a break.
Lane Departure Alert with Steering Assist
(LDA w/SA)
Press the LDA switch to turn the LDA system on. Depress again to turn it\
off.
Note: Operation of the LDA system and setting adjustments continues in the
same condition regardless of Ignition cycle until changed by the driver or the
system is reset.
Refer to the Toyota Owner’s Manual for additional information on LDA \
operation,
settings adjustments, limitations, and precautions before attempting to \
use it.

To change the vehicle-to-vehicle distance

Push the “
” button to cycle
through the settings, which will
change progressively.
This mode employs a radar sensor to detect the presence of a preceding v\
ehicle
up to approximately 328 ft (100 m) ahead, determines the current vehic\
le-to-vehicle
following distance and operates to maintain a preset following distance \
from the
vehicle ahead. These distances vary based on vehicle speed.

(1) Constant speed cruising when there are no vehicles ahead
The vehicle travels at the speed set by the driver. The desired vehicle-\
to-
vehicle distance can also be set by operating the vehicle-to-vehicle dis\
tance
control.
(2) Deceleration cruising and follow-up cruising when a preceding vehicle
driving slower than the set speed appears When a vehicle is detected running ahead of you, the system automaticall\
y
decelerates your vehicle. When a greater reduction in vehicle speed is
necessary, the system applies the brakes (the brake lights will come on\
at this
time). The system will respond to changes in the speed of the vehicle a\
head
in order to maintain the vehicle-to-vehicle distance set by the driver. \
A warning
tone warns you when the system cannot decelerate sufficiently to prevent\
your
vehicle from closing in on the vehicle ahead.
Note: Vehicle-to-vehicle distance will close in when traveling on long downhill
slopes.

SWITCHING TO CONSTANT SPEED (CRUISE) CONTROL MODE
SETTING CONSTANT SPEED (CRUISE) CONTROL
Note: When your vehicle is too close to a vehicle ahead, and sufficient automatic
deceleration via the cruise control is not possible, 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.
If you are already using DRCC “”, push ON-OFF button to turn the system off
first, then push and hold ON-OFF button for at least 1.5 seconds to swit\
ch.
Note: When the engine is turned off, it will automatically default to DRCC.
Refer to the Toyota Owner’s Manual for additional information on DRCC\
operation,
settings adjustments, limitations, and precautions before attempting to \
use it.
(3) 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 constant speed cruising.
To adjust speed or cancel, see steps (2) and (3) of ADJUSTING SET SPEED on
page 37.
