the radar sensor and front camera,
preventing the system from operating
properly:

object is wobbling
• If a detectable object makes an abrupt
maneuver (such as sudden swerving,
acceleration or deceleration)

detectable object rapidly
• When a detectable object is not
directly in front of your vehicle
• When a detectable object is near a
wall, fence, guardrail, manhole cover,
vehicle, steel plate on the road, etc.
• When a detectable object is under a

: If equipped
While driving on a road with clear
white (yellow) lane lines, the LTA
system warns the driver if the vehi-
cle may deviate from the current
lane or course
*
, and also can
slightly operate the steering wheel
to help avoid deviation from the
lane or course
*
. Also, while the
dynamic radar cruise control is
operating, this system will operate
the steering wheel to maintain the
vehicle’s lane position.
The LTA system recognizes white
(yellow) lane lines or a course
*
using the front camera. Additionally,
it detects preceding vehicles using
the front camera and radar.

WARNING
■
Before using LTA system
●
Do not rely solely upon the LTA sys-
tem. The LTA system does not
automatically drive the vehicle 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 attention to
the surrounding conditions and
operating the steering wheel to cor-
rect 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 driv-
ing operations and pay careful
attention may lead to an accident,
resulting in death or serious injury.
■
Situations unsuitable for LTA
system
In the following situations, use the
LTA switch to turn the system off. Fail-
ure to do so may lead to an accident,
resulting in death or serious injury.
●
Vehicle is driven on a road surface
which is slippery due to rainy
weather, fallen snow, freezing, etc.
●
Vehicle is driven on a snow-cov-
ered road.
●
White (yellow) lines are difficult to
see due to rain, snow, fog, dust,
etc.
●
Vehicle is driven in a temporary
lane or restricted lane due to con-
struction work.
●
Vehicle is driven in a construction
zone.
●
A spare tire, tire chains, etc., are
equipped.
●
When the tires have been exces-
sively worn, or when the tire infla-
tion pressure is low.
●
When your vehicle is towing a
trailer or during emergency towing.
■
Preventing LTA system malfunc-
tions and operations performed
by mistake
●
Do not modify the headlights or
place stickers, etc., on the surface
of the lights.
●
Do not modify the suspension, etc.
If the suspension, etc., needs to be
replaced, contact any authorized
Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
●
Do not install or place anything on
the hood or grille. Also, do not
install a grille guard (bull bars, kan-
garoo bar, etc.).
●
If your windshield needs repairs,
contact any authorized Toyota
retailer or Toyota authorized
repairer, or any reliable repairer.
■
Conditions in which functions
may not operate properly
In the following situations, the func-
tions may not operate properly 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.234) and the
preceding vehicle changes lanes.

WARNING
■
Before using dynamic radar
cruise control with full-speed
range
●
Driving safely is the sole responsi-
bility of the driver. Do not rely solely
on the system, and drive safely by
always paying careful attention to
your surroundings.
●
The dynamic radar cruise control
with full-speed range provides driv-
ing assistance to reduce the
driver’s burden. However, there are
limitations to the assistance pro-
vided.
Read the following conditions care-
fully. Do not overly rely on this system
and always drive carefully.
• When the sensor may not be cor-
rectly detecting the vehicle ahead:

WARNING
• Conditions under which the vehicle-
to-vehicle distance control mode
may not function correctly:
P.249
●
Set the speed appropriately
depending on the speed limit, traffic
flow, road conditions, weather con-
ditions, etc. The driver is responsi-
ble for checking the set speed.
●
Even when the system is function-
ing normally, the condition of the
preceding vehicle as detected by
the system may differ from the con-
dition observed by the driver.
Therefore, the driver must always
remain alert, assess the danger of
each situation and drive safely.
Relying solely on this system or
assuming the system ensures
safety while driving can lead to an
accident, resulting in death or seri-
ous 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 driving
assist systems
Observe the following precautions, as
there are limitations to the assistance
provided by the system. Failure to do
so may cause an accident resulting in
death or serious injury.
●
Assisting the driver to measure fol-
lowing distance
The dynamic radar cruise control with
full-speed range is only intended to
help the driver in determining the fol-
lowing distance between the driver’s
own vehicle and a designated vehicle
traveling ahead. It is not a mechanism
that allows careless or inattentive
driving, and it is not a system that can
assist the driver in low-visibility condi-
tions.
It is still necessary for driver to pay
close attention to the vehicle’s sur-
roundings.
●
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 prevent or avoid
collisions with vehicles ahead of your
vehicle. Therefore, if there is ever any
possibility of danger, the driver must
take immediate and direct control of
the vehicle and act appropriately in
order to ensure the safety of all
involved.

WARNING
■
Situations unsuitable for
dynamic radar cruise control
with full-speed range
Do not use dynamic radar cruise con-
trol with full-speed range in any of the
following situations. Doing so may
result in inappropriate speed control
and could cause an accident resulting
in death or serious injury.
●
Roads where there are pedestrians,
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 high-
ways
●
When weather conditions are bad
enough that they may prevent the
sensors from detecting correctly
(fog, snow, sandstorm, heavy rain,
etc.)
●
When there is rain, snow, etc., on
the front surface of the radar or
front camera
●
In traffic conditions that require fre-
quent repeated acceleration and
deceleration
●
When your vehicle is towing a
trailer or during emergency towing
●
When an approach warning buzzer
is heard often
