4-5. Using the driving support systems
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.
*: Boundary between asphalt and the
side of the road, such as grass, soil,
or a curb
LTA (Lane Tracing
Assist)
Summary of functions
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.

WARNING
■Before using dynamic radar cruise control
●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 provides driving assistance to
reduce the driver’s burden. How- ever, there are limitations to the assistance provided.
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:  P. 1 9 0
• Conditions under which the vehicle- to-vehicle distance control mode may not function correctly: P. 1 9 1
●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 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 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 driving, 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 vehicle’s sur-
roundings.

WARNING
●Assisting the driver to judge proper following distance
The dynamic radar cruise control
determines whether the following dis-
tance between the driver’s own vehi-
cle 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 vig-
ilant 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
does not include functions which will
prevent or avoid collisions with vehi-
cles ahead of your vehicle. Therefore,
if there is ever any possibility of dan-
ger, 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
Do not use dynamic radar cruise con-
trol 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
●During emergency towing
●When an approach warning buzzer is heard often

versus right side driver position.) If the vehicle is driven to a region where the over-
taking lane is on a different side from where the vehicle is no rmally driven, the vehi-
cle may accelerate when the turn signal lever is operated in th e 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 over-
taking lane is to the left, the vehicle may accelerate when the right turn signal is acti-
vated).
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 syst em then returns to
constant speed cruising.
