WARNING
■ 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 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 mecha-
nism 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.
● 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
4
designated vehicle traveling ahead is within a set range. It is not capable
of making 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 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 control with full-speed range 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, 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 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 or front
camera
● In traffic conditions that require frequent repeated acceleration and decel-
eration
● During emergency towing
● When an approach warning buzzer is heard often

Driving in vehicle-to-vehicle distance control mode
This mode employs a radar to detect the presence of vehicles up to
approximately 328 ft. (100 m) ahead, determines the current vehicle-
to-vehicle following distance, and operates to maintain a suitable fol-
lowing distance from the vehicle ahead. The desired vehicle-to-vehi-
cle distance can also be set by operating the vehicle-to-vehicle
distance switch.
When driving on downhill slopes, the vehicle-to-vehicle distance may
become shorter.

Example of constant speed cruising
1
When there are no vehicles ahead
The vehicle travels at the speed set by the driver.
Example of deceleration cruising and follow-up cruising
2
When a preceding vehicle driving slower than the set speed
appears
When a vehicle is detected running ahead of you, the system automatically
decelerates your vehicle. When a greater reduction in vehicle speed is
necessary, the system applies the brakes (the stop lights will come on at
this time). The system will respond to changes in the speed of the vehicle
ahead in order to maintain the vehicle-to-vehicle distance set by the driver.
Approach warning warns you when the system cannot decelerate suffi-
ciently to prevent your vehicle from closing in on the vehicle ahead.
When the vehicle ahead of you stops, your vehicle will also stop (vehicle is
stopped by system control). After the vehicle ahead starts off, pressing the
“+ RES” switch or depressing the accelerator pedal (start-off operation) will
resume follow-up cruising. If the start-off operation is not performed, sys-
tem control continues to keep your vehicle stopped.
286
4-5. Using the driving support systems
When 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
accelerate to help to overtake a passing vehicle.
The system’s identification of what is an overtaking lane may be deter-
mined 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
vehicle 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 right turn signal is activated).
Example of acceleration
3
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.

BSM function
The BSM function uses radar sensors to detect vehicles that are trav-
eling in an adjacent lane in the area that is usually not reflected in the
outside rear view mirror (the blind spot), and advises the driver of the
vehicles existence via the outside rear view mirror indicator.
BSM function detection areas
The areas that vehicles can be detected in are outlined below.
4
The range of the detection area is:
1
Approximately 1.6 ft. (0.5 m) to 11.5 ft. (3.5 m) from either side of
the vehicle
The area between the side of the vehicle and 1.6 ft. (0.5 m) from the side
of the vehicle cannot be detected.
2
Approximately 3.3 ft. (1 m) forward of the rear bumper
3
Approximately 9.8 ft. (3 m) from the rear bumper
Approximately 9.8 ft. (3 m) to 197 ft. (60 m) from the rear bumper

WARNING
■ Cautions regarding the use of the system
The driver is solely responsible for safe driving. Always drive safely, taking
care to observe your surroundings.
The BSM function is a supplementary function which alerts the driver that a
vehicle is present in the blind spot. Do not overly rely on the BSM function.
The function cannot judge if it is safe to change lanes, therefore over reli-
ance could cause an accident resulting in death or serious injury.
According to conditions, the system may not function correctly. Therefore
the driver’s own visual confirmation of safety is necessary.
■ The BSM function is operational when
● The BSM function is turned on
● Vehicle speed is greater than approximately 10 mph (16 km/h).
■ The BSM function will detect a vehicle when
● A vehicle in an adjacent lane overtakes your vehicle.

■ If “Clean dirt from lens” is displayed on the audio system screen
A rear camera lens may be dirty or covered with snow or ice. In such cases, if
it is removed from the rear camera lens, the system should return to normal.
(It may be necessary to drive the vehicle for some time before the system
returns to normal.)
■ If “RCD unavailable” is displayed on the audio system screen
● If this message is displayed after the 12-volt battery has been disconnected
and reconnected, fully turn the steering wheel to the left and then the right
on level ground.
● If this message is displayed only when the R shift position is selected, the
rear camera lens may be dirty. Clean the rear camera lens.
■ Situations in which the system may not operate properly
● Some pedestrians, such as the following, may not be detected by the rear
camera detection function, preventing the function from operating properly:
• Pedestrians who are squatting
• Pedestrians who are lying down
• Pedestrians who are running

• Pedestrians who suddenly enter the detection area
• Pedestrians riding a bicycle, skateboard, or other light vehicle
• Pedestrians wearing unusual clothing, such as a costume
• Pedestrians whose body is partially hidden by a cart or other object
• Pedestrians which are obscured by darkness, such as at night
● In some situations, such as the following, pedestrians may not be detected
by the rear camera detection function, preventing the function from operat-
ing properly:
• When backing up in inclement weather (rain, snow, fog, etc.)
• When the rear camera is obscured (dirt, snow, ice, etc. are attached) or
scratched
• When a very bright light, such as the sun, or the headlights of another
vehicle, shines directly into the rear camera
• When backing up in a place where the surrounding brightness changes
suddenly, such as at the entrance or exit of a garage or underground
parking lot

4-5. Using the driving support systems
● In some situations, such as the following, the rear camera detection function
may operate even though there are no pedestrians in the detection area.
•
When a three dimensional object, such as a pole, traffic cone, fence, or
parked vehicle, is detected
•
When a moving object, such as a car or motorcycle is detected
•
When backing up toward moving objects such as flags or puddles, or air-
borne matter, such as smoke, steam, rain, or snow
•
When there is a pattern on the road, due to the road being made of cob-
blestone or gravel or having tram rails, traces of repair, white lines,
pedestrian crossings or fallen leaves on the surface
•
When backing up on a metal cover (grating), such as those used for
drainage ditches
•
When backing up toward the roadside or a bump in the road
•
When an object is reflected in a puddle or on a wet road surface
•
When there are shadows on the road
•
When backing up over a bump in the road
•
If the vehicle is significantly tilted, such as when carrying a heavy load
•
When backing up toward an incline/decline
•
If the suspension has been modified or tires of a size other than specified
are installed
•
If the rear of the vehicle is raised or lowered due to the carried load
•
If an electronic component, such as a backlit license plate or rear fog
light, is installed near the rear camera
•
If a bumper protector, such as an additional trim strip, is installed to the
rear bumper
•
If the orientation of the rear camera has been changed due to a collision
or other impact, or removal and installation
•
If a towing eyelet is installed to the rear of the vehicle
•
When the rear camera is obscured (dirt, snow, ice, etc. are attached) or
scratched
•
When water is flowing over the rear camera lens
•
If there is a flashing light in the detection area, such as the emergency
flashers of another vehicle
■ Situations in which the rear camera detection function may be difficult to
notice
● If buzzer may be difficult to hear if the surrounding area is noisy, the volume
of the audio system volume is high, the air conditioning system is being
used, etc.
● If the temperature in the cabin is extremely high or low, the audio system
screen may not operate correctly.
