■Situations in which the system may
not operate properly
●In certain situations, such as the fol-
lowing, a detectable object may not be detected by the front sensors, and the system may not operate properly:
• When a detectable object is approaching your vehicle• When your vehicle or a detectable
object is wandering • When a detectable object makes an abrupt maneuver (such as sudden
swerving, acceleration or decelera- tion)• When suddenly approaching a detect-
able object • When the detectable object is near a wall, fence, guardrail, manhole cover,
steel plate on the road surface, or another vehicle• When there is a structure above a
detectable object • When part of a detectable object is hidden by another object (large lug-
gage, umbrella, guardrail, etc.) • When multiple detectable objects are overlapping
• When a bright light, such as the sun, is reflecting off of a detectable object• When a detectable object is white and
looks extremely bright • When the color or brightness of a detectable object causes it to blend in
with its surroundings • When a detectable object cuts in front of or suddenly emerges in front of
your vehicle • When approaching a vehicle which is diagonal
• If a vehicle ahead is a child sized bicy- cle, is carrying a large load, is carrying an extra passenger, or has an unusual
shape (bicycles equipped with a child seat, tandem bicycles, etc.)• If a pedestrian or bicycle is shorter
than approximately 1 m (3.2 ft.) or taller than approximately 2 m (6.5 ft.).• When the silhouette of a pedestrian or
bicycle is unclear (such as when they are wearing a raincoat, long skirt, etc.)• When a pedestrian or bicycle is bend-
ing forward or squatting
• When a pedestrian or bicycle is mov- ing at high speed• When a pedestrian is pushing a
stroller, wheelchair, bicycle or other vehicle• When a detectable object blends in
with the surrounding area, such as when it is dim (at dawn or dusk) or dark (at night or in a tunnel)
• When the vehicle has not been driven for a certain amount of time after the EV system was started
• While turning left/right or a few sec- onds after turning left/right• While driving around a curve and a
few seconds after driving around a curve• When turning left/right and an oncom-
ing vehicle is driving in a lane 3 or more lanes from the vehicle• When turning left/right and the direc-
tion of the vehicle differs greatly from the direction traffic flows in the oncoming lane
• When turning left/right and approach- ing a pedestrian which was traveling
in the same direction as the vehicle and continues straight
●In addition to the preceding, in certain situations, such as the following, the emergency steering assist may not
operate properly:

Owners Manual_Europe_M42D76_en
5-4. Using the driving support systems
When driving on a road with
clear lane lines with the dynamic
radar cruise control operating,
lane lines and preceding and
surrounding vehicles are
detected using the front camera
and radar sensor, and the steer-
ing wheel is operated to maintain
the vehicle’s lane position.
Use the this function only on highways
and expressways.
If the dynamic radar cruise control is
not operating, the function will not oper-
ate.
In situations where the lane lines are
difficult to see or are not visible, such as
when in a traffic jam, support will be
provided using the path of preceding
and surrounding vehicles.
If the system determines that the steer-
ing wheel has not been operated for a
certain amount of time or the steering
wheel is not being firmly gripped, the
driver will be alerted via a display and
this function will be temporarily can-
celed.
If the steering wheel is firmly gripped,
the function will begin operating again.
 When the function is operating, if
the vehicle is likely to depart from
its lane, the driver will be alerted
via a display and buzzer.
When the buzzer sounds, check the
area around the vehicle and carefully
operate the steering wheel to move the
vehicle back to the center of the lane.

■Operating conditions of function
This function is operable when all of the following conditions are met:
●The LTA system detects lane lines or
the path of preceding or surrounding
vehicles (except when the preceding vehicle is small, such as a motorcy-cle).
●The dynamic radar cruise control is operating.
●The lane width is approximately 3 to 4 m (10 to 13 ft.).
●The turn signal lever is not being oper-ated.
●The vehicle is not being driven around a sharp curve.
●The vehicle is not accelerating or decelerating more than a certain
amount.
●The steering wheel is not being turned
with a large force.
●The hands off steering wheel warning
( P.296) is not operating.
●The vehicle is being driven in the
center of a lane.
■Temporary cancelation of functions
●When the operating conditions are no
longer met, a function may be tempo- rarily canceled. However, when the operation conditions are met again,
operation of the function will automati- cally be restored. ( P.295)
●If the operating conditions of a func- tion are no longer met while the func-tion is operating, a buzzer may sound
to indicate that the function has been temporarily canceled.
●The steering assist operation of the function can be overridden by the steering wheel operation of the driver.
■Lane departure warning function
when the LTA is operating
●Even if the LDA warning method is
changed to vibration of the steering wheel, if the vehicle deviates from the lane while the LTA is operating, the
warning buzzer will sound to alert the driver.
●If steering wheel operation equivalent to that necessary for a lane change is
WARNING
■Before using the LTA system
●Do not overly rely on the LTA sys-tem. The LTA system is not a sys-
tem which provides automated assistance in driving and it is not a system which reduces the amount
of attention necessary for safe driv- ing. The driver is solely responsible for paying attention to their sur-
roundings and operating the steer- ing wheel as necessary to ensure safety. Also, the driver is responsi-
ble for taking adequate breaks when fatigued, such as when driv-ing for a long time.
●Failure to perform appropriate driv-ing operations and pay careful
attention may lead to an accident.
●When not using the LTA system,
turn it off using the LTA switch.

lane departure alert function or lane
departure prevention function may not operate.
●The lane departure alert function or lane departure prevention function may not operate if the system judges
that the vehicle is intentionally being steered to avoid a pedestrian or parked vehicle.
●It may not be possible for the system to judge if there is danger of a collision
with a vehicle in an adjacent lane.
●The steering assist operation of the
lane departure prevention function can be overridden by the steering
wheel operation of the driver.*: Boundary between the asphalt and
grass, soil, etc., or structures, such as
a curb, guardrail, etc.
■Hands off steering wheel warning
operation
In the following situations, a message urging the driver to operate the steering
wheel and an icon will be displayed and a buzzer will sound to warn the driver. When using the system, make sure to
grip the steering wheel firmly, regardless of whether the warning is operating or not.
●When the system determines that the driver is not securely holding the
steering wheel, or the steering wheel is not being operated when the steer-ing assist operation of the lane depar-
ture prevention function is operating

When the front camera detects a
sign or information of a sign is
available from the navigation
system (if equipped), the sign will
be displayed on the display.
 Multiple signs can be displayed.
Depending on the specifications of the
vehicle, the number of displayed signs
may be limited.
■Operating conditions of sign dis- play
Signs will be displayed when the follow-
ing conditions are met:
●The system has detected a sign
In the following situations, a displayed sign may stop being displayed:
●When a new sign has not been detected for a certain distance
●When the system determines that the road being driven on has changed, such as after a left or right turn
■Situations in which the display
function may not operate properly
In the following situations, the RSA sys- tem may not operate properly and may
not detect signs or may display the incorrect sign. However, this does not indicate a malfunction.
●When a sign is dirty, faded, tilted or bent
●When the contrast of an electronic sign is low
●When all or part of a sign is hidden by a tree, utility pole, etc.
●When a sign is detected by the front
camera for a short amount of time
●When the driving state (turning,
changing lanes, etc.) is judged incor- rectly
●When a sign is immediately after a freeway junction or in an adjacent lane just before merging
●When stickers are attached to the rear of a preceding vehicle
●When a sign similar to a system com-patible sign is detected as a system
compatible sign

road is within detection range of the front camera
RSA (Road Sign Assist)
The RSA system detects spe-
cific road signs using the front
camera and/or navigation sys-
tem (if equipped) (when speed
limit information is available)
and warns the driver via dis-
plays and buzzers.
WARNING
■For safe use
●Driving safely is solely the responsi- bility of the driver. Pay careful atten-tion to the surrounding conditions in
order to ensure safe driving.
●Do not rely solely upon the RSA.
The RSA assists the driver by pro- viding road sign information, but it is not a replacement for the driver’s
own vision and awareness. Driving safely is solely the responsibility of the driver. Pay careful attention to
the surrounding conditions in order to ensure safe driving.
■Situations in which the RSA should not be used

Dynamic radar cruise
control
This dynamic radar cruise con-
trol detects the presence of
vehicles ahead, determines the
current vehicle-to -vehicle dis-
tance, and operates to main-
tain a suitable distance from
the vehicle ahead. The desired
vehicle-to-vehicle distance can
be set by operating the vehi-
cle-to-vehicle distance switch.
Use the dynamic radar cruise
control only on highways and
expressways.
WARNING
■For safe use
●Driving safely is solely the responsi- bility of the driver. Do not overly rely
on this system, and pay careful attention to the surrounding condi-tions in order to ensure safe driving.
●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 fol-
lowing items carefully. Do not overly rely on this system and always drive carefully.
Conditions under which the system may not operate correctly: P.313
●Set the speed appropriately accord- ing to the speed limit, traffic flow,
road conditions, weather condi- tions, etc. The driver is responsible for confirming the set speed.

WARNING
●Even if the system is operating cor- rectly, the condition of a preceding
vehicle as recognized by the driver and detected by the system may differ. Therefore, it is necessary for
the driver to pay attention, assess risks, and ensure safety. Over-reli-ance on this system to drive the
vehicle safely may lead to an acci- dent resulting in death or serious injury.
■Precautions for the driving assist systems
Observe the following precautions, as there are limitations to the assistance provided by the system. Over-reliance
on this system may lead to an acci- dent resulting in death or serious injury.
●Details of support provided for the driver’s vision The dynamic radar
cruise control is only intended to help the driver in determining the distance between the driver’s own
vehicle and a designated preceding vehicle. It is not a system which allows for careless or inattentive
driving, and is not a system which assists in poor visibility conditions. The driver must pay attention to
their surroundings, even when the vehicle stops.
●Details of support provided for the driver’s judgement The dynamic radar cruise control determines
whether the distance between the driver’s own vehicle and a desig-nated preceding vehicle is within a
set range. It is not capable of mak- ing any other type of judgement. Therefore, it is absolutely neces-
sary for the driver to remain vigilant and to determine whether or not there is a possibility of danger.
●Details of support provided for the driver’s operation The dynamic radar cruise control does not
include functions which will prevent or avoid collisions with vehicles 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 safety.
■Situations in which the dynamic radar cruise control should not be used
Do not use the dynamic radar cruise control in the following situations. As the system will not be able to provide
appropriate control, using it may lead to an accident resulting in death or serious injury.
●Roads where there are pedestrians, cyclists, etc.
●When driving on a highway or expressway entrance or exit
●When the approach warning sounds frequently
●Situations in which the sensors may not operate properly: P.279
●Situations in which the lane may not be detected: P. 2 8 1
