appears as if it may depart from
its lane multiple times, the
warning buzzer sounds and a

the driver.
WARNING
■Before using LDA system
Do not rely solely upon the LDA system. LDA is not a system which auto-
matically drives the vehicle or reduces 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 always paying careful attention to the sur-
rounding conditions and operate the steering wheel to correct the path of
the vehicle. Also, make sure to 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.
■ To avoid operating LDA by mistake
When not using the LDA system, use the LDA switch to turn the system off.

WARNING
■Situations unsuitable for LDA
Do not use the LDA system in the following situations.
The system may not operate properly and lead to an accident, resulting in
death or serious injury.
● A spare tire, tire chains, etc., are equipped.
● When the tires have been excessively worn, or when the tire inflation pres-
sure is low.
● Tires which differ by structure, manufacturer, brand or tread pattern are
used.
● Objects or patterns that could be mistaken for white (yellow) lines are
present on the side of the road (guardrails, curbs, reflective poles, etc.).

any dirt, rain, condensation, ice,
snow, etc., from the windshield, and
then turn the LDA system back on.
“Forward Camera

The LDA system is temporarily can-
celed because the operating condi-
tions of the camera sensor
(temperature, et c.) are not met.

WARNING
■Before using dynamic radar cruise control
Driving safely is the sole responsibility of the driver. Do not rely solely on the
system, and drive safely by always paying careful attention to your sur-
roundings.
The dynamic radar cruise control provides driving assistance to reduce the
driver's burden. However, there are limitations to the assistance provided.
Even when the system is functioning normally, the condition of the preced-
ing vehicle as detected by the system may differ from the condition
observed by the driver. Therefore, th e driver must always remain alert,
assess the danger of each situation and drive safely. Relying on this system
or assuming the system ensures safety while driving can lead to an acci-
dent, resulting in death or serious injury.
■ 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 following 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 care-
less 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 surroundings.
● Assisting the driver to judge proper following distance
The dynamic radar cruise control determines whether the following dis-
tance 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 has li mited capability to prevent or avoid
a collision with a vehicle traveling ahead. Therefore, if there is ever any
danger, the driver must take immediate and direct control of the vehicle
and act appropriately in order to ensure the safety of all involved.
■ To avoid inadvertent dynamic radar cruise control activation
Switch the dynamic radar cruise control off using the “ON-OFF” button
when not in use.

WARNING
■Situations unsuitable for dynamic radar cruise control
Do not use dynamic radar cruise control in any of the following situations.
Doing so may result in inappropriate speed control and could cause an acci-
dent resulting in death or serious injury.
● Roads where there are pedestrians, cyclers, 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 prevent the sen-
sors from detecting correctly (fog, snow, sandstorm, heavy rain, etc.)
● When there is rain, snow, etc. on the front surface of the radar sensor or
camera sensor
● In traffic conditions that require frequent repeated acceleration and decel-
eration
● When an approach warning buzzer is heard often
