Vehicles that can be detected
by the Blind Spot Monitor
The Blind Spot Monitor uses radar sensors to detect the followi ng
vehicles traveling in adjacent lanes and advises the driver of the
presence of such vehicles via the indicators on the outside rea r
view mirrors.
Vehicles that are traveling in a reas that are not visible using the
outside rear view mirrors (the blind spots)
Vehicles that are approaching rapidly from behind in areas that
are not visible using the outside rear view mirrors (the blind
spots)

r detection areas
The areas that vehicles can be detected in are outlined below.
The range of each detection area is:
Approximately 1.6 ft. (0.5 m) to 11.5 ft. (3.5 m) from either s ide 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.
Approximately 3.3 ft. (1 m) f orward of the rear bumper
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
*
*
: The greater the difference in speed between your vehicle and the
detected vehicle is, the farther away the vehicle will be detec ted, caus-
ing the outside rear view mirror indicator to illuminate or flash.
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 Blind Spot Monitor is a supplementary function which alerts the driver
that a vehicle is in a blind spot of the outside rear view mirr ors or is
approaching rapidly from behind into a blind spot. Do not overl y rely on the
Blind Spot Monitor.
As the function cannot judge if it is safe to change lanes, ove r reliance could
lead to an accident resulting in death or serious injury. As the system may
not function correctly under certain conditions, the driver’s o wn visual confir-
mation of safety is necessary.

■The Blind Spot Monitor is operational when
The Blind Spot Monitor is operational when all of the following conditions are
met:
● The engine switch is in the IGNITION ON mode.
● The Blind Spot Monitor is on.
● The shift lever is in a position other than R.
● The vehicle speed is greater than approximately 10 mph (16 km/h ).
■ The Blind Spot Monitor will detect a vehicle when
The Blind Spot Monitor will detect a vehicle present in the det ection area in
the following situations:
● A vehicle in an adjacent lane overtakes your vehicle.
● You overtake a vehicle in adjacent lane slowly.
● Another vehicle enters the detection area when it changes lanes.
■ Conditions under which the system will not detect a vehicle
The Blind Spot Monitor is not designed to detect the following types of vehi-
cles and/or objects:
● Small motorcycles, bicycles, pedestrians, etc.
*
●Vehicles traveling in the opposite direction
● Guardrails, walls, signs, parked vehicles and similar stationar y objects
*
●Following vehicles that are in the same lane*
●Vehicles traveling 2 lanes away from your vehicle*
●Vehicles which are being overtaken rapidly by your vehicle.*
*
: Depending on the conditions, detection of a vehicle and/or obj ect may
occur.

Conditions under which the system may not function correctly
●The Blind Spot Monitor may not detect vehicles correctly in the following sit-
uations:
• When the sensor is misaligned due to a strong impact to the se nsor or its
surrounding area
• When mud, snow, ice, a sticker, etc. is covering the sensor or surround-
ing area on the rear bumper
• When driving on a road surface that is wet with standing water during bad
weather, such as heavy rain, snow, or fog
• When multiple vehicles are approaching with only a small gap b etween
each vehicle
• When the distance between your vehicle and a following vehicle is short
• When there is a significant difference in speed between your v ehicle and
the vehicle that enters the detection area
• When the difference in speed between your vehicle and another vehicle
is changing
• When a vehicle enters a detection area traveling at about the same
speed as your vehicle
• As your vehicle starts from a stop, a vehicle remains in the d etection area
• When driving up and down consecutive steep inclines, such as hills, dips 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) or towing eyelet 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 Monitor is turned on
● Instances of the Blind Spot Monitor unnecessarily detecting a vehicle and/or
object may increase in the following situations:
• When the sensor is misaligned due to a strong impact to the se nsor or its
surrounding area
• When the distance between your vehicle and a guardrail, wall, etc. that
enters the detection area is short
• When driving up and down consecutive steep inclines, such as h ills, 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 vehicle and a following vehicle is short
• When an accessory (such as a bicycle carrier) or towing eyelet is
installed to the rear of the vehicle
• When the vehicle throws up water or snow behind.

Intuitive parking assist
: If equipped
The distance from your vehicle to nearby obstacles when paral-
lel parking or maneuvering into a garage is measured by the
sensors and communicated via t he multi-information display
and a buzzer. Always check the surrounding area when using
this system.

Buzzer operation and di
stance to an obstacle
A buzzer sounds when the sensors are operating.
● The buzzer sounds faster as the vehicle approaches an obstacle.
When the vehicle comes within the following distance of the
obstacle, the buzzer sounds continuously: Approximately 1.2 ft.
(35 cm).
● When 2 or more obstacles are detected simultaneously, the
buzzer system responds to the nearest obstacle. If one or both
come within the above distances , the beep will repeat a long
tone, followed by fast beeps.
Approximately 2.0 ft. (60 cm)
Approximately 4.9 ft. (150 cm)
The diagram shows the detection
range of the sensors. Note that the
sensors cannot detect obstacles
that are extremely close to the
vehicle.
The range of the sensors may
change depending on the shape of
the object etc.
