approaching rapidly from behind into a
blind spot, the outside rear view mirror
indicator on the detected side will illumi-
nate. If the turn signal lever is operated
toward the detected side, the outside
rear view mirror indicator flashes.

BSM (Blind Spot Moni-
tor)*
The Blind Spot Monitor is a
system that uses rear side
radar sensors installed on the
inner side of the rear bumper
on the left and right side to
assist the driver in confirming
safety when changing lanes.
WARNING
■Cautions regarding the use of
the system
●The driver is solely responsible for safe driving. Always drive safely,
taking care to observe your sur- roundings.
●The Blind Spot Monitor is a supple-mentary function which alerts the driver that a vehicle is in a blind
spot of the outside rear view mirrors or is approaching rapidly from
behind into a blind spot. Do not overly rely on the Blind Spot Moni-tor. As the function cannot judge if it
is safe to change lanes, over reli- ance could lead to an accident resulting in death or serious injury.
As the system may not function cor- rectly under certain conditions, the
driver’s own visual confirmation of safety is necessary.

in the road, etc.
• When driving on roads with sharp bends, consecutive curves, or uneven surfaces
• When vehicle lanes are wide, or when driving on the edge of a lane, and the vehicle in an adjacent lane is far away
from your vehicle • When an accessory (such as a bicycle carrier) is installed to the rear of the
vehicle • When there is a significant difference in height between your vehicle and
the vehicle that enters the detection area• Immediately after the Blind Spot Moni-
tor is turned on • When towing with the vehicle
●Instances of the Blind Spot Monitor unnecessarily detecting a vehicle and/or object may increase in the fol-
lowing situations: • When the sensor is misaligned due to a strong impact to the sensor or its
surrounding area • When the distance between your vehi-cle and a guardrail, wall, etc., that
enters the detection area is short • When driving up and down consecu-tive steep inclines, such as hills, dips
in the road, etc. • When vehicle lanes are narrow, or when driving on the edge of a lane,
and a vehicle traveling in a lane other than the adjacent lanes enters the detection area
• When driving on roads with sharp bends, consecutive curves, or uneven surfaces
• When the tires are slipping or spinning • When the distance between your vehi-cle and a following vehicle is short
• When an accessory (such as a bicycle carrier) is installed to the rear of the vehicle
• When towing with the vehicle
*: If equipped
SEA (Safe Exit Assist)*
The Safe Exit Assist is a sys-
tem that uses radar sensors
installed on the inner side of
the rear bumper to help occu-
pants judge if an approaching
vehicle or bicycle may collide
with a door to reduce the pos-
sibility of a collision.
WARNING
■Cautions regarding the use of
the system
●The driver is solely responsible for safe driving. Always drive safely,
taking care to observe your sur- roundings.
●Safe Exit Assist is a supplementary system that, when the vehicle is stopped, informs occupants of the
existence of approaching vehicles and bicycles. As this system alone cannot be used to judge safety,
over-reliance on this system may lead to an accident resulting in death or serious injury.
As the system may not function cor- rectly under certain conditions, visual confirmation of safety with
the passengers’ own eyes and mir- rors is necessary.

ing such as a rain coat, long skirt, etc.,
making their silhouette obscure • Pedestrians whose body is partially hidden by an object, such as a cart or
umbrella • Pedestrians which are obscured by darkness, such as at night
●In some situations, such as the follow-ing, pedestrians may not be detected
by the rear camera detection function, preventing the function from operating 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 vehi- cle, shines directly into the rear cam-era
• When backing up in a place where the surrounding brightness changes sud-denly, such as at the entrance or exit
of a garage or underground parking lot• When backing up in a dim environ-
ment such as during dusk or in an underground parking lot• When the camera position and direc-
tion are deviated • When a towing hook is attached• When water droplets are flowing on
the camera lens • When the vehicle height is extremely changed (nose up, nose down)
• When tire chains or an emergency tire puncture repair kit is used• When the rear washer is operating
• If the suspension has been modified or tires of a size other than specified are installed.
• 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
■Situations in which the system may
operate unexpectedly
●Even though there are no pedestrians
in the detection area, some objects,
such as the following, may be detected, possibly causing the rear camera detection function to operate.
• Three dimensional objects, such as a pole, traffic cone, fence, or parked vehicle
• Moving objects, such as a car or motorcycle• Objects moving toward your vehicle
when backing up, such as flags or puddles (or airborne matter, such as smoke, steam, rain, or snow)
• Cobblestone or gravel roads, tram rails, road repairs, white lines, pedes-trian crossings or fallen leaves on the
road • Metal covers (gratings), such as those used for drainage ditches
• Objects reflected in a puddle or on a wet road surface• Shadows on the road
●In some situations, such as the follow-ing, the rear camera detection func-
tion may operate even though there are no pedestrians in the detection area.
• When backing up toward the roadside or a bump on the road• When backing up toward an
incline/decline • If the rear of the vehicle is raised or lowered due to the carried load
• 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• If a towing eyelet is installed to the
rear of the vehicle • When water is flowing over the rear camera lens
• When the rear camera is obscured (dirt, snow, ice, etc., are attached) or scratched

WARNING
■Cautions regarding the use of
the system
Do not overly rely on the system, as doing so may lead to an accident.
Always drive while checking the safety of the surroundings of the vehi-cle.
Depending on the vehicle and road conditions, weather, etc., the system may not operate.
The detection capabilities of sensors and radars are limited. Always drive while checking the safety of the sur-
roundings of the vehicle.
●The driver is solely responsible for
safe driving. Always drive carefully, taking care to observe your sur-roundings. The Parking Support
Brake system is designed to pro- vide support to lessen the severity of collisions. However, it may not
operate in some situations.
●The Parking Support Brake system
is not designed to stop the vehicle completely. Additionally, even if the system has stopped the vehicle, it
is necessary to depress the brake pedal immediately as brake control will be canceled after approximately
2 seconds.
●It is extremely dangerous to check
the system operations by intention- ally driving the vehicle into the direction of a wall, etc. Never
attempt such actions.
■When to disable the Parking Sup- port Brake
In the following situations, disable the
Parking Support Brake as the system may operate even though there is no possibility of a collision.
●When inspecting the vehicle using a chassis roller, chassis dynamo or
free roller
●When loading the vehicle onto a
boat, truck or other transport vessel
●If the suspension has been modi-
fied or tires of a size other than specified are installed
●If the front of the vehicle is raised or lowered due to the carried load
●When equipment that may obstruct a sensor is installed, such as a tow-ing eyelet, bumper protector (an
additional trim strip, etc.), bicycle carrier, or snow plow
●When using automatic car washing devices
●If the vehicle cannot be driven in a stable manner, such as when the vehicle has been in an accident or
is malfunctioning
●When the vehicle is driven in a
sporty manner or off-road
●When the tires are not properly
inflated
●When the tires are very worn
●When a tire chains, compact spare tire or an emergency tire puncture
repair kit is used
■Precautions for the suspension
Do not modify the suspension of the vehicle. If the height or tilt of the vehi-cle is changed, the sensors may not
be able to detect detectable objects and the system may not operate cor-rectly, possibly leading to an accident.
