LTA (Lane Tracing
Assist)*
When driving on highways
and freeways with white
(yellow) lane lines, this
function alerts the driver
when the vehicle might
depart from its lane or
course
* and provides assis-
tance by operating the
steering wheel to keep the
vehicle in its lane or
course
*. Furthermore, the
system provides steering
assistance when dynamic
radar cruise control with
full-speed range is operat-
ing to keep the vehicle in its
lane.
The LTA system recognizes
white (yellow) lane lines or a
course
* using the front cam-
era. Additionally, it detects
preceding vehicles using
the front camera and radar.
*: Boundary between asphalt and the side of the road, such as
grass, soil, or a curb
WARNING
■Before using LTA system
●Do not rely solely upon the LTA
system. The LTA system does
not automatically drive the vehi-
cle or reduce the amount of
attention that must be paid to
the area in front of the vehicle.
The driver must always assume
full responsibility for driving
safely by paying careful atten-
tion to the surrounding condi-
tions and operating the steering
wheel to correct the path of the
vehicle. Also, the driver must
take adequate breaks when
fatigued, such as from driving
for a long period of time.
●Failure to perform appropriate
driving operations and pay care-
ful attention may lead to an
accident, resulting in death or
serious injury.
●When not using the LTA system,
use the LTA switch to turn the
system off.
■Situations unsuitable for LTA
system
In the following situations, use the
LTA switch to turn the system off.
Failure to do so may lead to an
accident, resulting in death or
serious injury.

This function is linked with
dynamic radar cruise control
with full-speed range and pro-
vides the required assistance by
operating the steering wheel to
keep the vehicle in its current
lane.
When dynamic radar cruise control
with full-speed range is not operat-
ing, the lane centering function
does not operate.
In situations where the white (yel-
low) lane lines are difficult to see or
are not visible, such as when in a
traffic jam, this function will operate
to help follow a preceding vehicle
by monitoring the position of the
preceding vehicle.
If the system detects that the steer-
ing wheel has not been operated
for a fixed amount of time or the
steering wheel is not being firmly
gripped, a warning is displayed on the multi-information display and
the function is temporarily can-
celed.
Press the LTA switch to turn the
LTA system on.

■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 attention 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.
• When the sensor may not be correctly detecting the vehicle
ahead:
P.213
• Conditions under which the vehicle-to-vehicle distance con-
trol mode may not function cor-
rectly:
P. 2 1 4
●Set the speed appropriately
depending on the speed limit,
traffic flow, road conditions,
weather conditions, etc. The
driver is responsible for check-
ing the set speed.
●Even when the system is func-
tioning normally, the condition of
the preceding vehicle as
detected by the system may dif-
fer from the condition observed
by the driver. Therefore, the
driver must always remain alert,
assess the danger of each situ-
ation and drive safely. Relying
solely on this system or assum-
ing the system ensures safety
while driving can lead to an
accident, resulting in death or
serious injury.
●Switch the dynamic radar cruise
control with full-speed range
setting to off, using the cruise
control main switch when not in
use.
■Cautions regarding the driv-
ing assist systems
Observe the following precau-
tions, as there are limitations to
the assistance provided by the
system.
Failure to do so may cause an
accident resulting in death or seri-
ous injury.

WARNING
●Assisting the driver to measure
following distance
The dynamic radar cruise control
with full-speed range is only
intended to help the driver in
determining the following distance
between the driver’s own vehicle
and a designated vehicle traveling
ahead. It is not a mechanism that
allows careless or inattentive driv-
ing, and it is not a system that can
assist the driver in low-visibility
conditions.
It is still necessary for driver to
pay close attention to the vehi-
cle’s surroundings.
●Assisting the driver to judge
proper following distance
The dynamic radar cruise control
with full-speed range determines
whether the following distance
between the driver’s own vehicle
and a designated vehicle traveling
ahead is within a set range. It is
not capable of making any other
type of judgement. Therefore, it is
absolutely necessary for the
driver to remain vigilant and to
determine whether or not there is
a possibility of danger in any
given situation.
●Assisting the driver to operate
the vehicle
The dynamic radar cruise control
with full-speed range does not
include functions which will pre-
vent or avoid collisions with vehi-
cles ahead of your vehicle.
Therefore, if there is ever any
possibility of dange r, the driver
must take immediate and direct
control of the vehicle and act
appropriately in order to ensure
the safety of all involved.
■Situations unsuitable for
dynamic radar cruise control
with full-speed range
Do not use dynamic radar cruise
control with full-speed range in
any of the following situations.
Doing so may result in inappropri-
ate speed control and could
cause an accident resulting in
death or serious injury.
●Roads where there are pedes-
trians, cyclists, etc.
●In heavy traffic
●On roads with sharp bends
●On winding roads
●On slippery roads, such as
those covered with rain, ice or
snow
●On steep downhills, or where
there are sudden changes
between sharp up and down
gradients
Vehicle speed may exceed the
set speed when driving down a
steep hill.
●At entrances to freeways and
highways
●When weather conditions are
bad enough that they may pre-
vent the sensors from detecting
correctly (fog, snow, sand-
storm, heavy rain, etc.)
●When there is rain, snow, etc.
on the front surface of the radar
or front camera
●In traffic conditions that require
frequent repeated acceleration
and deceleration
●During emergency towing
●When an approach warning
buzzer is heard often

2084-5. Using the driving support systems
COROLLA H/B_UWhen the turn signal lever is operated and your vehicle moves to an over-
taking lane while driving at 50 mph (
80 km/h) or more, the vehicle will accel-
erate to help to overtake a passing vehicle.
The system’s identification of what is an overtaking lane may be determined
solely based on the location of the steering wheel in the vehicle (left side
driver position versus right side driver position.) If the vehicle is driven to a
region where the overtaking lane is on a different side from where the vehi-
cle is normally driven, the vehicle may accelerate when the turn signal lever
is operated in the opposite direction to the overtaking lane (e.g., if the driver
normally operates the vehicle in a region where the overtaking lane is to the
right but then drives to a region where the overtaking lane is to the left, the
vehicle may accelerate when the ri ght 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 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. 2 1 1 )
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.

cancels the speed control.
The speed control is also canceled
when the brake pedal is depressed.
(When the vehicle has been
stopped by system control,
depressing the brake pedal does
not cancel the setting.)
2Pressing the “+RES” switch
resumes the cruise control
and returns vehicle speed to
the set speed.
When your vehicle is too close
to a vehicle ahead, and suffi-
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
